  3. The North Korean nuclear dilemma

    2004-01-01

    The current nuclear crisis, the second one in ten years, erupted when North Korea expelled international nuclear inspectors in December 2002, then withdrew from the Nuclear Nonproliferation Treaty (NPT), and claimed to be building more nuclear weapons with the plutonium extracted from the spent fuel rods heretofore stored under international inspection. These actions were triggered by a disagreement over U.S. assertions that North Korea had violated the Agreed Framework (which froze the plutonium path to nuclear weapons to end the first crisis in 1994) by clandestinely developing uranium enrichment capabilities providing an alternative path to nuclear weapons. With Stanford University Professor John Lewis and three other Americans, I was allowed to visit the Yongbyon Nuclear Center on Jan. 8, 2004. We toured the 5 MWe reactor, the 50 MWe reactor construction site, the spent fuel pool storage building, and the radiochemical laboratory. We concluded that North Korea has restarted its 5 MWe reactor (which produces roughly 6 kg of plutonium annually), it removed the 8000 spent fuel rods that were previously stored under IAEA safeguards from the spent fuel pool, and that it most likely extracted the 25 to 30 kg of plutonium contained in these fuel rods. Although North Korean officials showed us what they claimed was their plutonium metal product from this reprocessing campaign, we were not able to conclude definitively that it was in fact plutonium metal and that it came from the most recent reprocessing campaign. Nevertheless, our North Korean hosts demonstrated that they had the capability, the facility and requisite capacity, and the technical expertise to produce plutonium metal. On the basis of our visit, we were not able to address the issue of whether or not North Korea had a 'deterrent' as claimed - that is, we were not able to conclude that North Korea can build a nuclear device and that it can integrate nuclear devices into suitable delivery systems. However

    2017-01-01

    As North Korea performed new ballistic missile tests in February 2017, and thus violated UN resolutions, this article proposes an overview of the evolutions from nuclear sanctions to economic sanctions. Initially, UN sanctions aimed at struggling against nuclear programmes and proliferation through embargo on arms and materials. After a nuclear test in 2016, South Korea withdrew from a North Korean industrial complex. International sanctions now aim at economically isolating North Korea, at increasing its trade deficit, and at reducing the sending of currencies by North-Korean expatriates. The author notices that these sanctions do not alter manufacturing activities, and that North Korea thus keeps on developing and being integrated into the international division of labour. The last part briefly discusses how North Korea could be able to get around sanctions

    This paper focuses on the North Korean nuclear crisis and how to find the best method of dismantling the North's nuclear facilities. From empirical studies of North Korean negotiating behavior, strategy, intentions and future of the regime, North Korea seems unlikely to abandon its nuclear program, if left unconstrained. This paper analyzes North Korean nuclear strategy and discusses problems concerned with the North Korean nuclear issues. It will propose some resolutions for a comprehensive approach in order to find a solution to the North Korean nuclear threat: restarting the six-party talks; preparation of a sophisticated nuclear elimination road-map; encouraging the gradual transformation of North Korea and its integration into the international community. In the long run, when North Korean nuclear strategy is considered, dialogue and engagement combined with international pressure or proper sanctions is needed

  8. Seismological analysis of the fourth North Korean nuclear test

    2016-04-01

    The Democratic People's Republic of Korea has conducted its fourth underground nuclear explosions on 06.01.2016 at 01:30 (UTC). The explosion was clearly detected and located by the seismic network of the International Monitoring System (IMS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Additional seismic stations of international earthquake monitoring networks at regional distances, which are not part of the IMS, are used to precisely estimate the epicenter of the event in the North Hamgyong province (41.38°N / 129.05°E). It is located in the area of the North Korean Punggye-ri nuclear test site, where the verified nuclear tests from 2006, 2009, and 2013 were conducted as well. The analysis of the recorded seismic signals provides the evidence, that the event was originated by an explosive source. The amplitudes as well as the spectral characteristics of the signals were examined. Furthermore, the similarity of the signals with those from the three former nuclear tests suggests very similar source type. The seismograms at the 8,200 km distant IMS station GERES in Germany, for example, show the same P phase signal for all four explosions, differing in the amplitude only. The comparison of the measured amplitudes results in the increasing magnitude with the chronology of the explosions from 2006 (mb 4.2), 2009 (mb 4.8) until 2013 (mb 5.1), whereas the explosion in 2016 had approximately the same magnitude as that one three years before. Derived from the magnitude, a yield of 14 kt TNT equivalents was estimated for both explosions in 2013 and 2016; in 2006 and 2009 yields were 0.7 kt and 5.4 kt, respectively. However, a large inherent uncertainty for these values has to be taken into account. The estimation of the absolute yield of the explosions depends very much on the local geological situation and the degree of decoupling of the explosive from the surrounding rock. Due to the missing corresponding information, reliable magnitude-yield estimation for the

  9. Third North Korean nuclear test: what is the state of the North's programme?

    2013-02-01

    Two months ago, following North Korea's Unha-3 launch, which put a small satellite into orbit, this publication discussed the possibility of a third North Korean nuclear test. As expected, Pyongyang remained true to its traditional policy of provocation. With carefully calculated timing, it carried out a third nuclear test on 12 February, just hours after Barack Obama's State of the Union address, four days before former leader Kim Jong-il's birthday, and on the eve of the investiture of the new South Korean president on the 25 February. Moreover, the North Korean regime is billing this test as a riposte to the new round of sanctions adopted on by the Security Council on 22 January following the Unha-3 launch in December, as it announced on the 24 January. Yet, aside from the associated posturing, this test confirms, if more confirmation were needed, the North's determination to develop an effective nuclear deterrent. The use of the term miniaturisation is certainly in part a propaganda exercise (can actual miniaturisation be achieved after three nuclear tests, one or two of whose success is highly doubtful?). Nonetheless, North Korea has clearly made progress in developing a nuclear weapon and an intercontinental ballistic missile derived from the Taepodong-2, and has promised to carry out further ballistic launches. Without a doubt, even if the North is a long way from possessing what we would consider an operational nuclear capability, its determination has helped it to make progress, and the country shows no signs of wanting to change course. In light of this fact, what can the international community do beyond existing and future sanctions regimes? Doubtless very little. China, which continues to support the North and which has been known in the past to exert influence on Pyongyang, has expressed its firm displeasure as to the North's activities but appears to have no leverage over Kim Jong-un. The Six-Party talks have little chance of being revived, as North

The author analyzes the influence of the American nuclear spectrum in East Asia and the interactions with the nuclear spectra of North Korea and Japan. He shows that the American nuclear umbrella deeply influences the inter-state relations between the two Korea and Japan

  11. Implications of a North Korean Nuclear Weapons Program

    1993-07-01

    The Democratic People`s Republic of Korea (DPRK) is one of the Cold War`s last remaining totalitarian regimes. Rarely has any society been as closed to outside influences and so distant from political, economic, and military developments around the globe. In 1991 and in 1992, however, this dictatorship took a number of political steps which increased Pyongyang`s interaction with the outside world. Although North Korea`s style of engagement with the broader international community involved frequent pauses and numerous steps backward, many observers believed that North Korea was finally moving to end its isolated, outlaw status. As the end of 1992 approached, however, delay and obstruction by Pyongyang became intense as accumulating evidence suggested that the DPRK, in violation of the nuclear Non-Proliferation Treaty (NPT), was seeking to develop nuclear weapons. On March 12, 1993, North Korea announced that it would not accept additional inspections proposed by the International Atomic Energy Agency (IAEA) to resolve concerns about possible violations and instead would withdraw from the Treaty. Pyongyang`s action raised the specter that, instead of a last act of the Cold War, North Korea`s diplomatic maneuvering would unravel the international norms that were to be the basis of stability and peace in the post-Cold War era. Indeed, the discovery that North Korea was approaching the capability to produce nuclear weapons suggested that the nuclear threat, which had been successfully managed throughout the Cold War era, could increase in the post-Cold War era.

  12. IAEA team to visit North Korean nuclear facilities

    2002-01-01

    A technical team from the IAEA will visit nuclear facilities in the Nyongbyon area of the Democratic People's Republic of Korea (DPRK) from 15-19 January. The visit will include the Isotope Production Laboratory, an installation that the DPRK has stated was involved in the early stages of development of their nuclear programme. Since 1993, the IAEA has been unable to fully implement its comprehensive safeguards agreement with the DPRK, and has been therefore unable to verify the completeness and correctness of the DPRK's initial 1992 declaration of its nuclear inventory. In May 2001, the IAEA proposed to the DPRK concrete steps that need to be carried out in that verification process, and indicated its readiness to start implementing these measures immediately. At a technical meeting between the DPRK and the IAEA in November 2001, the DPRK did not agree to promptly start to implement those proposals, citing the delay in implementation of the USA/DPRK Agreed Framework as the principal reason for declining. However, the DPRK did agree to a visit, not an inspection, by IAEA inspectors to the Isotope Production Laboratory. The DPRK withdrew its membership from the Agency in June 1994. The Director General encourages the DPRK to normalize its relations with the IAEA including resumption of full safeguards inspections

    Underground nuclear explosions (UNEs) can induce acoustic-gravity waves, which disturb the ionosphere and initiate traveling ionospheric disturbances (TIDs). In this paper, we employ a multi-step and multi-order numerical difference method with dual-frequency GPS data to detect ionospheric disturbances triggered by the North Korean UNE on 25 May 2009. Several International GNSS Service (IGS) stations with different distances (400 to 1200 km) from the epicenter were chosen for the experiment. The results show that there are two types of disturbances in the ionospheric disturbance series: high-frequency TIDs with periods of approximately 1 to 2 min and low-frequency waves with period spectrums of 2 to 5 min. The observed TIDs are situated around the epicenter of the UNE, and show similar features, indicating the origin of the observed disturbances is the UNE event. According to the amplitudes, periods and average propagation velocities, the high-frequency and low-frequency TIDs can be attributed to the acoustic waves in the lower ionosphere and higher ionosphere, respectively.

    Since the first nuclear test on 15 July 1945 , there have been over 2,051 other weapon tests around the world . The waveforms of a natural earthquake which generates strong S waves and an underground explosion which is dominated by P waves were distinguished from the analysis of data corresponding to a 2005 M5.0 Earthquake and a 2016 North Korean nuclear test , both at similar distances from seismometer . Further differences between the seismograms were evaluated and successfully distinguished between the origins of the elastic waves through the data using Moment Tensor Solution using stations BJT , HIA and INCN . North Korea has developed a nuclear fuel cycle capability and has both plutonium and enriched uranium programs at Pyongyang . Seismic recordings of vertical ground motion at Global Seismographic Network station IC.MDJ of the 4 seismic events at Punggye-ri , North Korea , which occurred on the 9th of October 2006 , 25th of May 2009, 12th of February 2013 and on the 6th of January and 9th of September , 2016 were examined and the P waves of these seismic waves , which show very similar wave form , were inspected and compared to the seismic data of the latest underground nuclear test on the 3rd of September 2017 at 03:30 UTC at the same site which is many times more powerful than the previous tests . The country , which is the only nation to have tested nuclear weapons in this millennium , has successfully prevented the release of radioactive isotopes and hampered data collection but further studies were done using acoustic data which was analysed from sonograms of the 4 North Korean tests at station MDJ. The latest explosion data from 3rd September was also compared to 42 presumed underground explosions which occurred in China , India , the U.S.S.R , Iran , Turkey and recorded at Arkansas Seismic Network.

  16. Accurate relative location estimates for the North Korean nuclear tests using empirical slowness corrections

    Declared North Korean nuclear tests in 2006, 2009, 2013 and 2016 were observed seismically at regional and teleseismic distances. Waveform similarity allows the events to be located relatively with far greater accuracy than the absolute locations can be determined from seismic data alone. There is now significant redundancy in the data given the large number of regional and teleseismic stations that have recorded multiple events, and relative location estimates can be confirmed independently by performing calculations on many mutually exclusive sets of measurements. Using a 1-D global velocity model, the distances between the events estimated using teleseismic P phases are found to be approximately 25 per cent shorter than the distances between events estimated using regional Pn phases. The 2009, 2013 and 2016 events all take place within 1 km of each other and the discrepancy between the regional and teleseismic relative location estimates is no more than about 150 m. The discrepancy is much more significant when estimating the location of the more distant 2006 event relative to the later explosions with regional and teleseismic estimates varying by many hundreds of metres. The relative location of the 2006 event is challenging given the smaller number of observing stations, the lower signal-to-noise ratio and significant waveform dissimilarity at some regional stations. The 2006 event is however highly significant in constraining the absolute locations in the terrain at the Punggye-ri test-site in relation to observed surface infrastructure. For each seismic arrival used to estimate the relative locations, we define a slowness scaling factor which multiplies the gradient of seismic traveltime versus distance, evaluated at the source, relative to the applied 1-D velocity model. A procedure for estimating correction terms which reduce the double-difference time residual vector norms is presented together with a discussion of the associated uncertainty. The modified

    The world today is confronted by North Korea that has apparently acquired successfully nuclear weapons, and by Iran that seems bent on acquiring, at a minimum, a virtual nuclear weapons capability. This trend suggests that prospects for freezing, if not rolling back, both Iran's and North Korea's programs are becoming increasingly difficult prospects. While President George W. Bush came under attack for going to war with Iraq based on faulty intelligence assessments and also for labeling Iran, Iraq and North Korea as part of the 'axis of evil', it cannot be denied that the world's 'most dangerous states with the most dangerous weapons' remain one of the defining security challenges of the post-9/11 era. Nevertheless, the Bush Administration's efforts to prevent, and failing that, to minimize the fallout from a nuclearized North Korea and a potentially nuclear capable Iran, have been decidedly mixed. Although North Korea maintained nuclear ambiguity for two decades, it finally gave up the pretense of having a 'virtual nuclear weapons program' in October 2006 whereas Iran continues on the path of nuclear brinkmanship. Whether Iran is going to cross the nuclear Rubicon remains uncertain but the fact that it has the requisite technologies and the political will to cross the nuclear threshold if it chose to do so remains unchanged. Regardless of Tehran's ultimate choice and attendant strategic consequences, Iran cannot but have gained key glimpses and insights from North Korea's decades-long pursuit of nuclear weapons. While Iran and North Korea have vastly different political histories and national ideologies, their paths have criss-crossed on the road towards nuclearization. Tehran and Pyongyang are not 'natural' allies although Iran has benefited from North Korea's ballistic missile sales (such as the Shahab-3 long-range missile). For its part, Pyongyang has gained not only from missile exports to Iran, but perhaps more significantly, by Iran's own nuclear challenge

    On 13 February, the Third Session of the Fifth Round of the Six-Party Talks ended with the adoption of the 'Action Plan' for the implementation of the September 2005 Joint Statement.2 The Action Plan has two phases - the initial phase and the 'next' phase - but the core of the deal lies in the initial stage in which the parties agreed to exchange the nuclear freeze and the provision of energy. In the initial phase, North Korea will 'shut down and seal' the Yongbyon nuclear facility, including the reprocessing facility, and invite back International Atomic Energy Agency (IAEA) personnel to conduct monitoring and verifications within 60 days. In return, the other parties of the talks will provide emergency energy assistance equivalent to 50,000 tons of heavy fuel oil (HFO) to North Korea. There are other items in the initial stage such as North Korea discussing a list of all its nuclear programs with other parties, and the United States and North Korea starting bilateral talks toward full diplomatic relations. However, these items are rather nominal and symbolic in nature and will not likely produce meaningful results in a short period of time. The second phase is even more open-ended. In the second phase, North Korea will provide a complete declaration of all nuclear programs and disable all existing nuclear facilities. In return, the other parties will provide economic, energy and humanitarian assistance up to the equivalent of 950,000 tons of HFO. However, the timing and the details of the nuclear 'disablement' and the provision of assistance are not specified, making it likely that the parties will disagree over how to interpret the words in the Action Plan. The Action Plan provides that five Working Groups (WG) on different topics will be established in order to discuss the details, but the effectiveness of the WG remains to be seen. The Action Plan, therefore, represents the lowest common denominator for the parties involved. In agreeing to the plan, all

    Full Text Available This paper aims to explain the adaptation of North Korean elite defectors who fled from North Korea. Data used for the purpose of this article came from surveys of North Korean defectors conducted in the late 2000’s. Findings of the realized research indicate that the majority of senior defectors are experiencing less psychological and material issues when adjusting to society than regular North Korean defectors. The paper will proceed in three steps: explaining the notion of defectors, outlining their background, and focusing on their adaptation in South. Although defectors as a whole has emerged as of the most research group as a minority in South Korea, the so-called senior defectors have hardly been spotlighted. Basically North Korean senior defectors are supposed to strengthen the anti-Kim movement and legitimize the power of the South Korean government and the image of South Korea abroad. What has to be enlightened upon is the fact that North Korean senior defectors partially disagree with the integration policy of South Korean authorities. A major research question emerges: How are the experience of elite defectors localized in South Korea? How do their specific identities impact their opinion within the South Korean society? The aim of the article is also to categorize senior defectors and to provide in a single document a list of senior North Korea defectors based abroad. This kind of information is only available for Korean speaking readers. I wanted to make it accessible to the Englishspeaking community.

  5. Infrasound Observation of the Apparent North Korean Nuclear Test of 25 May 2009

    On 25 May 2009, a seismic event (mb 4.6) was recorded from a source in northeastern North Korea, close to the location of a previous seismic event on 9 October 2006. Both events have been declared to be nuclear tests. Five seismo-acoustic arrays in South Korea recorded epicentral infrasonic signals for the more recent test following the strong seismic waves from the explosion. This study describes the characteristics of the nuclear test-generated infrasound signals observed at infrasound arrays located from 304 to 528 km from the source. The signals were characterized by stratospheric returns with amplitudes from 0.16 to 0.35 microbar and dominant frequencies between 1.0 and 4.3 Hz. Celerities determined for the arrivals suggest that most of the infrasonic energy travelled as a stratospheric phase. The inferred infrasonic location was offset about 15.7 km from the reference seismic location. On the basis of observed amplitudes of the stratospheric phases and corrections based on prevailing winds, the epicentral infrasonic energy was estimated to be equivalent to that expected from about 2.2 ton surface detonation of conventional explosives. We conclude that this small energy estimate is related to the partitioning of the contained explosive energy resulting from the interaction of strong ground motion at the surface with the atmosphere rather than the direct transfer of explosion energy to the air. This relatively small energy ratio between the infrasonic energy and the seismic energy could be used to distinguish the event from a common surface explosion.

Esta posición contrastaba con su pasada oposición a las sanciones a Corea del Norte. China no cambiaría sus principios en las relaciones con Corea del Norte debido a sus propios intereses de seguridad en la península coreana. No obstante, China se vio obligada a asumir un papel de mediadora en la comunidad internacional y dar una lección a su problemático aliado norcoreano.

    Under new circumstances, that is after the end of the Cold War, the current security situation in Northeast Asia and Korean peninsula is reviewed. The South Korean Non-proliferation policy and its strong commitment to the NPT is embodied in the following: treaty commitments; government officials' statements; presidential declarations; North/South joint declarations; and domestic laws and regulations.Korea has made efforts towards denuclearisation of Korean peninsula. Its nuclear policy is based on peaceful uses of nuclear energy and on maintaining a strong commitment to the NPT. The ultimate goal of its policy is to deter North Korea from developing nuclear weapons and thus secure a nuclear-free Korean peninsula. This could lay foundation for the ultimate creation of region-wide nuclear-free zone in Northeast Asia

    After the cold war, the North Korea nuclear problem become the dominant problem between U.S. - North Korean relationship, and became the profoundest factor to the regional security in the Korean Peninsula and Northeast A-sia. North Korea nuclear crisis is caused by complex and profound historical and realistic background. After World War I-I, the Korean Peninsula was split into two parts, the North and the South. Korean War in the 1950s’ and “cold peace”between the South and the North in the past forty years are the main causes of nuclear crisis in North Korea. Superfi-cially, North Korean nuclear crisis is the result of “nuclear proliferation”. However, if we probe into this problem further, we may find that the core reason of the North Korean nuclear crisis is the Korea Peninsula security pattern changes in the relations between DPRK rigid contradictions after the cold war.%  朝鲜核危机是冷战后主导美朝关系,并深刻影响朝鲜半岛安全和东北亚地区稳定局势的最大因素。朝鲜核危机有着复杂而深刻的历史与现实背景,朝鲜半岛在二战后的南北分裂,上世纪50年代的朝鲜战争以及战后南北双方持续四十几年的“冷和平”状态,是朝核危机的深层次背景因素。表面上看,朝鲜核危机是由于“核扩散”而引发的,但是,透过朝核危机的表象,朝鲜核危机爆发的根本原因是冷战后朝鲜半岛安全格局发生的变化与朝美关系僵化不变的矛盾对立,是“此变”与“彼不变”对立冲突的结果。

    2012-01-01

    Korean nuclear Official Development Assistance (ODA) is established with support from institutes such as the Korea International Cooperation Agency (KOICA) and the Korea Atomic Energy Research Institute (KAERI). KOICA's grant aid mainly made through the activities including IAEA's training program, and KAERI currently runs the inter-regional education and training cooperation called Asian Network for Education in Nuclear Technology(ANENT) which aimed to achieve the goal of encouraging web based education training network via cooperation with IAEA. Yet now these programs are focusing more on assisting nuclear infrastructure rather than highlighting nuclear education and training. This paper aims to, first, do a self-evaluation about the Korean ODA policy; second, to study the transition of the international nuclear atmosphere; and third, by apprehending the trend of the subjects of Korean nuclear ODA policy, to discuss the overall appropriate trajectory of Korean nuclear ODA

    We investigated the performance of North Korean refugees on attention tasks, and the relationship between that performance and psychiatric symptoms. Sustained and divided attention was assessed using the computerized Comprehensive Attention Test in North Korean refugees and in South Koreans. All participants also completed the Beck Depression Inventory, the Beck Anxiety Inventory, the Impact of Event Scale-Revised and the Dissociative Experiences Scale-II (DES-II). The North Korean refugees showed slower reaction times (RTs) on the visual sustained attention task compared to the South Koreans after controlling for age and sex. North Korean refugees had a greater number of omission errors (OEs) on the divided attention task and a higher standard deviation (SD) of RT. Total DES-II scores of the North Korean refugees were associated with the number of OEs and the SD of RT on the sustained attention task, and with the number of OEs on the divided attention task. North Korean refugees showed poorer performance on computerized attention tasks. In addition, attention deficit among North Korean refugees was associated with their dissociative experiences. Our results suggest that refugees may have attention deficits, which may be related to their psychiatric symptoms, particularly dissociation.

    On 6 January 2016, the Democratic People's Republic of Korea announced to have conducted its fourth nuclear test. Analysis of the corresponding seismic waves from the Punggye-ri nuclear test site showed indeed that an underground man-made explosion took place, although the nuclear origin of the explosion needs confirmation. Seven weeks after the announced nuclear test, radioactive xenon was observed in Japan by a noble gas measurement station of the International Monitoring System. In this paper, atmospheric transport modelling is used to show that the measured radioactive xenon is compatible with a delayed release from the Punggye-ri nuclear test site. An uncertainty quantification on the modelling results is given by using the ensemble method. The latter is important for policy makers and helps advance data fusion, where different nuclear Test-Ban-Treaty monitoring techniques are combined.

    Full Text Available Purpose Although there have been studies emphasizing the re-education of North Korean (NK doctors for post-unification of the Korean Peninsula, study on the content and scope of such re-education has yet to be conducted. Researchers intended to set the content and scope of re-education by a comparative analysis for the scores of the preliminary examination, which is comparable to the Korean Medical Licensing Examination (KMLE. Methods The scores of the first and second preliminary exams were analyzed by subject using the Wilcoxon signed rank test. The passing status of the group of NK doctors for KMLE in recent 3 years were investigated. The multiple-choice-question (MCQ items of which difficulty indexes of NK doctors were lower than those of South Korean (SK medical students by two times of the standard deviation of the scores of SK medical students were selected to investigate the relevant reasons. Results The average scores of nearly all subjects were improved in the second exam compared with the first exam. The passing rate of the group of NK doctors was 75%. The number of MCQ items of which difficulty indexes of NK doctors were lower than those of SK medical students was 51 (6.38%. NK doctors’ lack of understandings for Diagnostic Techniques and Procedures, Therapeutics, Prenatal Care, and Managed Care Programs was suggested as the possible reason. Conclusion The education of integrated courses focusing on Diagnostic Techniques and Procedures and Therapeutics, and apprenticeship-style training for clinical practice of core subjects are needed. Special lectures on the Preventive Medicine are likely to be required also.

    2017-12-01

    We use constraints on the location of the January 6, 2016 DPRK announced nuclear test (2016_01) and differential travel times for Pn, Pg, and teleseismic P-waves to estimate the absolute locations of the 6 announced DPRK nuclear tests, as well as other nearby events. Absolute location constraints are based on the fit of commercial InSAR-derived ground displacement and predictions of elastic displacement from an isotropic source including topographic effects. Results show that the announced tests in January and September of 2016 are under the crest of highest local topography (Mt. Mantap), while the 2009 and 2013 events are south of the topographic crest at a similar contour in local topography. The first announced test in 2006 was located near the crest of a separate topographic high approximately 2.75 km east of the 2016_01 test. The September 3, 2017 event is approximately between the two 2016 tests, under the crest of the mountain ridge. Constraints from seismic data put the events within 1 km of the surface and depths may be inferred, with caution, by differencing the elevation of tunnel entrances and the topographic surface and accounting for the rise in a tunnel elevation from the entrance to facilitate drainage. Depths for the 2006_10, 2009_05, 2013_02, 2016_01, 2016_09, and 2017_09 tests are estimated to be 500 m, 530 m, 530 m, 740 m, 750 m, and 750 m, respectively. Other nearby events are considerably lower in magnitude, resulting in location estimates that are not as well constrained as the announced nuclear tests. Analysis of all events provides a bulletin of events that may occur in the future. Prepared by LLNL under Contract DE-AC52-07NA27344.

    Korean atomic energy activities have been the vigorous and ever expanding in the peaceful use of atomic energy. However for the last ten-year period, the new recruitments have been drastically reduced. The paper presents the nuclear manpower status in each nuclear related institute, which was surveyed in 2002. The ageing problem appears but is not very serious as a whole. The research institutes show more serious ageing problems compared to the industries. The paper also summarises the initiatives taken by Korean institutes related to the nuclear knowledge management activities with focus on the NtUss (Nuclear Technology Undergraduate Student Society) programme.

    2017-10-01

    Full Text Available Discourse on the Six Party Talks has focused solely on denuclearisation. Through the power struggles of the members and the refusal of the People’s Democratic Republic of Korea (DPRK to return to negotiations, the Six Party Talks have been stalled since 2008. Due to current increased tensions and the use of brinkmanship tactics the Talks must be restarted, albeit under a reformed shape. This paper analyses the potential role of the EU in furthering the peace process in Northeast Asia. This paper suggests that the EU needs to be more assertive and the Talks should focus on building trust and cooperation, not on the DPRK’s nuclear program. With its impartiality, experience in integration and use of soft power, the EU can act as an effective mediator building trust.

  4. How to realize a nuclear-free Korean peninsula

    Yun, Duk-min

    1992-01-01

    It is certain that, unless the nuclear issue is solved, there can be no progress in inter-Korean relations. To this end, comprehensive and intrusive mutual inspections of any suspicious sites, as well as IAEA inspections, should certainly be implemented. Once international and bilateral arrangements for nuclear inspection are agreed and implemented to the satisfaction of the parties concerned, this will not only solve the problem of nuclear proliferation, but also lay a firm foundation for greater confidence-building measures on the Korean peninsula. This could also be a valuable example for future arms control in Korea. However, even mutual inspection between the two Koreas cannot necessarily guarantee a nuclear-free Korea. The most effective way to ensure the denuclearization of Korea may be to remove elements that the two Koreas perceive as incentives to go nuclear, in parallel with operating a tight and stable verification regime based on mutual and international inspections. Since the major reasons to go nuclear in Korea are military threats and mutual distrust between the two Koreas, no efforts should be spared to rectify these situations. Therefore, confidence- and security-building measures, including full-scale arms control, must be carried out in order to realize and preserve a nuclear-free Korea. In the long run, the greatest contribution to reducing the threat of nuclear proliferation in the Korean peninsula will be through improving overall relations between South and North Korea

    The smoking rates and patterns in the North Korean population are not well known. More than 20,000 North Korean defectors have settled in South Korea; thus, we can estimate the current North Korean smoking situation using this group. All North Korean defectors spend their first 3 months in a South Korean facility learning to adapt to their new home. We retrospectively analyzed the results from a questionnaire conducted among North Korean male defectors in this facility from August 2012 to February 2014. Of 272 men, 84.2% were current smokers, 12.5% were ex-smokers, and 3.3% were non-smokers. The mean age of this group was 35.9 ± 11.3 years, and smoking initiation occurred at a mean age of 18.2 ± 4.7 years. Among the subjects, 78.1% had a family member who smoked. Of the 221 current smokers, 67.4% responded that they intended to quit smoking. Fagerström test and Kano test for social nicotine dependence (KTSND) results for current smokers were 3.35 ± 2.26 and 13.76 ± 4.87, respectively. Question 9 on the KTSND (doctors exaggerate the ill effects of smoking) earned a significantly higher score relative to the other questions and a significantly higher score in current smokers compared with non-smokers. The smoking rate in North Korean male defectors was higher than that indicated previously. However, interest in smoking cessation was high and nicotine dependence was less severe than expected. Further investigation is needed to identify an efficient method for North Korean smokers to stop smoking.

  15. The North-Korean-Syrian Connection: Take It Seriously But Address It Wisely

    2008-01-01

    The release of photographs of what U.S. officials say was a Syrian nuclear reactor built with North Korean assistance (and destroyed by Israel in September 2007) could undermine the success of ongoing negotiations with Pyongyang about its nuclear weapons activities. In addition to pressing Syria to admit its nuclear ambitions, the Bush Administration argues that the disclosure of these photographs will pressure Pyongyang to honor its lagging non-proliferation commitments laid out in a six-party agreement reached in February 2007. The problem is that this could also bring current negotiations to a breakdown. In other words, in the face of U.S. confrontation, North Korean officials could simply decide to walk out of the negotiating table altogether. In the recent past, the absence of a negotiating process with Pyongyang had dramatic consequences. Following the collapse of negotiations in 2002 (when Washington confronted Pyongyang with an alleged clandestine uranium enrichment program), North Korea moved swiftly to unfreeze its plutonium production facilities, expel international inspectors, withdraw from the Nuclear Non-Proliferation Treaty (NPT), restart its reprocessing activities and, finally, conduct a nuclear test in October 2006. During this period, the possibility of war and regional proliferation increased and many proliferation experts worried that the financially strapped Communist regime would attempt to sell its nuclear technology to anyone willing to buy it, including terrorist groups. A negotiating process was finally restored with the February 2007 agreement, which the Bush Administration hailed as a major breakthrough. Nearly fifteen months down the track, Pyongyang has closed and almost entirely disabled its main nuclear reactor (Yongbyon). But it has missed key deadlines to provide detailed information on its stocks of plutonium and nuclear weapons, its uranium enrichment program as well as a complete accounting of its past proliferation activities

    This paper is aiming at finding out an authentic meaning of implementation of the IAEA Strengthened Safeguards System (SSS) in South Korea, and also the implementation of the joint agreement in North Korea concluded among the six nations on Feb. 13, 2007. The approach for development of the paper would be limited to the dimension of nuclear control. The actual implementation of the Additional Protocol (AP) and the entry into force of the Integrated Safeguards System in a near future in South Korea have passed a few of technical and diplomatic complications. Specially the past mistakes related to declaration to IAEA made by researchers resulted in a more strengthened transparency policy in South Korea, which was announced as a form of four-point statement reassuring the international community of its commitment to a nuclear-free policy on the Korean peninsula in 2004. North Korea rejected special inspection demanded by IAEA in 1992 related to its initial declaration to apply the IAEA INFCIRC/153 type of safeguards system. The rejection had consisted of the base line of diplomatic conflict between North Korea and international community. However, change of position of North Korea, even being uncertain still as of today, arrived at the joint declaration of '9-19' among 6 nations of Six-Party Talks in 2005, which developed into the conclusion of joint agreement for the implementation of the '9-19' principles on Feb. 13, 2007

    Many countries have decided nuclear power for next energy resources as one of the long-term energy supply options. IAEA projected nuclear power expansion up to 2030 reaching between 447 GWe and 691 GWe compared to 370 GWe and 2660 TWh at the end of 2006. Both low and high projection is accompanied with new nuclear power plant constructions respectively 178 and 357, about 11 units per year, and most new construction is in North America, the Far East, Eastern Europe, the Middle East, and Southeast Asia. During the last forty years, thirty three countries have established commercial nuclear power programs but only some of them have developed comprehensive and large scale peaceful nuclear power infrastructure. Although various cooperation and guidance program of nuclear power infrastructure, developing appropriate environment and infrastructure of nuclear power plant is still challenging problems for developing countries launching nuclear power program. With increasing the demand of safety and safeguard from international society, creating appropriate infrastructure becomes essential requirements in national nuclear power program. In the viewpoint of developing countries, without sufficient explanation and proper guidance, infrastructure could be seen only as another barrier in its nuclear power program. The importance of infrastructure development would be obscured by ostensible business and infrastructure program can result in increasing entering barriers to peaceful nuclear power application field without benefits to developing countries and international community. To avoid this situation by providing enough explanation and realistic case example and cooperate with the countries wanting to establish comprehensive nuclear power infrastructure in the peaceful applications, we are creating the education program of infrastructure development with basic guidelines of the IAEA infrastructure series and Korean experiences from least developed country to advanced country

    North Korean refugees in South Korea are at high risk of depression, but there are few studies exploring protective factors in this population. We hypothesized that family functioning (family adaptability and cohesion) and resilience would protect North Korean refugees from developing depressive symptoms. A subsample of 304 adult North Korean refugees drawn from the cross-sectional 2010 Nationwide Survey of Domestic Violence in South Korea was analyzed. Approximately 44% of respondents were identified as having depression, using scores on the Center for Epidemiological Studies Depression scale. In models capturing the full spectrum of depressive symptoms (continuous), family cohesion was significantly associated with depression, and the relationship was partially mediated by resilience. In models predicting clinical depression (dichotomous), resilience fully mediated the relationship between family cohesion and clinical depression. In contrast, family adaptability was not associated with depression or resilience in this sample. These findings suggest that assessing and enhancing family cohesion and resilience may be essential for professionals working with refugees, and that refugees without family support may be at particularly high risk for depression.

    This thesis argues that the North Korean model of government is a unique model that is influenced, to varying degrees, by extreme leftist and rightist doctrines, including Marxism-Leninism, Stalinism, Maoism, fascism, and Nazism; and shares at least some similarities with all these established models. Rather than being a mere political model, the North Korean model is a political religion that incorporates traits of each of the above-noted models with Korean mythology, Confucianism, extreme ...

  4. North Korea's nuclear weapons development. Implications for future policy

    International Nuclear Information System (INIS)

    Pollack, J.D.

    2010-01-01

    This essay assesses North Korea's long-standing quest for nuclear weapons; alternative strategies for inhibiting Pyongyang's weapons development; and the potential implications for regional security and nonproliferation should the Democratic People's Republic of Korea (DPRK) retain and enhance its weapons programs. North Korea's pursuit of a nuclear weapons capability has long provoked heated debate among policy makers and research analysts about the purposes of engagement with the North, reflecting the repeated frustrations in efforts to negotiate Korean denuclearization. These debates reflect widely divergent views of the North Korean regime; its sustainability as an autonomous political, economic, and military system; and the potential consequences of continued nuclear development in this isolated, highly idiosyncratic state. These questions assume additional salience as North Korea approaches a leadership succession for only the second time in its six-decade history. The effort to inhibit North Korea's pursuit of nuclear weapons is among the longest running and least successful sagas in international security and non-proliferation policy of the past quarter century. In early 2010, Pyongyang claims a rudimentary nuclear capability by possession of weaponized plutonium, the conduct of two nuclear tests, and advances in the production of enriched uranium as an alternative means of fissile material production, though the latter step is nominally justified as a source for reactor fuel. North Korea defends its pursuit of a nuclear deterrent to counter what Pyongyang deems existential threats posed by the United States.Despite the resumption of high-level diplomatic contact between Washington and Pyongyang in late 2009, realization of a non-nuclear Korean Peninsula remains a very remote prospect. The DPRK insists that a peace agreement between the U.S. and North Korea and hence the cessation of 'hostile DPRK-U.S. relations' are necessary before any consideration of

    2017-11-01

    North Korean adolescent defectors experience adaptation difficulties along with a wide range of psychosocial problems, but no study has yet examined their Internet addiction symptoms. We compared early traumatic experiences, self-esteem, negative cognition, and Internet addiction symptoms, as well as the relationships between these variables, between North Korean adolescent defectors and South Korean adolescents. Fifty-six North Korean adolescent defectors and 112 age- and sex- matched South Korean adolescents participated. The analyses examined the relationship between traumatic experiences and Internet addiction symptoms, with negative automatic thoughts or low self-esteem as mediators of these relations. North Korean adolescent defectors tended to have higher levels of negative automatic thoughts and more severe Internet addiction symptoms, as well as better self-esteem, than did South Korean adolescents. Furthermore, only among North Korean adolescent defectors, traumatic experiences were positively associated with Internet addition symptoms via increasing negative automatic thoughts. North Korean adolescent defectors are more susceptible to Internet addiction, negative cognitions, and early traumatic experiences compared to South Korean adolescents. However, the cross-sectional design of this study precludes consideration of the causality of these relationships. Interventions aiming to correct negative cognitions and increase self-esteem may be helpful for North Korean adolescent defectors with problematic Internet use. Copyright © 2017 Elsevier B.V.

  10. Construction Improvement for the Korean Nuclear Program

    International Nuclear Information System (INIS)

    Yang, T. E.

    1992-01-01

    Construction of the nine Nuclear plants requires an enormous financial investment. The decision to build a nuclear unit is based on both economic and resource requirements. Korea has few natural resources to use for power generation so the use of diversified fuel sources is a part of the planning process. Nuclear has historically had economic advantages over the fossil fueled plant, however, this advantage has been reduced. This is mainly due to increasing decommissioning and waste disposal costs plus the financial outlays associated with gaining public acceptance of new nuclear units. One of the principal means to recover the economic advantage of a nuclear plant is to shorten the time needed for construction. Every extra day of construction costs large sums of money in interest and escalation expenses alone. The challenge is to shorten the construction period to the minimum feasible time and thereby reduce the financing costs. The methods that have to be employed to achieve this goal require the total commitment from the management of all entities involved in the program. Through the application of advanced management and construction techniques a new era in the construction of nuclear plants in Korea will occur. This will include changes to the methods used for managing, planning, licensing, designing and constructing the new plants. The ability to meet the aggressive plan for the construction of new nuclear power plants in Korea rests in the hands of the managers of all the parties involved. These men set all the rules by which the new plants will be constructed. It is their responsibility to tackle the current problems and develop the solutions to enable the plan to be realized. The changes suggested within this paper are major, but the potential benefits will allow the Korean Nuclear Industry to advance into the twenty first Century as a leader. The number of fully trained specialists needed to make this happen will not appear overnight. They will have to be

    Sunghoon Han

    2015-03-01

    Full Text Available This essay analyzes the Sinch’ŏn Massacre and its memorialization at the Sinch’ŏn Museum of American War Atrocities in North Korea by placing the massacre within the context of North Korea’s political history. The museum illustrates Pyongyang’s perspective on the Korean War as a “war of liberation” and the museum’s role in the political education of the North Korean people, not simply as victims of American war atrocities but as “martyrs” and model citizens. Within the geopolitics of confrontation between North Korea and the United States since the Korean War, the Sinch’ŏn Museum has served to foster anti-American nationalism in North Korea. While the museum has served this specific purpose within the North Korean context, it should be compared with other examples of war memorialization that serve the function of identity formation for a sense of national unity.

    1999-07-24

    A deteriorating economy, coupled with a series of natural disasters in 1995-97, led to a severe food crisis in North Korea. Although the country has received substantial international aid since 1996, demographic assessments of crisis impact have been limited. We assessed mortality trends in North Korea since 1995. At 15 randomly selected sites in China, 440 North Korean adult migrants were interviewed during July-September, 1998. Respondents were asked about births, deaths, and migration patterns in their households between mid-1994 and mid-1998, and about household food sources. The respondents also provided basic demographic information about the households of their relatives. We compared mortality rates from migrant households with data from the 1993 census and with data about households of non-migrant relatives. Households that included a recent migrant to China showed increasing mortality: crude death rates rose from 28.9 per 1000 in 1995, to 45.6 per 1000 in 1996, and to 56.0 per 1000 in 1997 (p=0.0001), with a 3-year average rate of 42.8 per 1000. The crude 3-year birth rate was 11.0 per 1000. Average household size declined from 4.0 at the beginning of 1995 to 3.4 at the end of 1997 (p=0.0002). Among 259 households of non-migrant relatives, the crude death rate was 43.2 per 1000 and the crude birth rate was 8.8 per 1000. In these households, the 3-year trend of increasing mortality was significant (p=0.001), as was the decline in average household size from 4.3 at the beginning of 1995 to 3.7 at the end of 1997 (p=0.0001). Among North Korean households that include a recent migrant to China, mortality has increased and household size has declined since 1995. This trend raises concern about the state of the general population, at least in the province of North Hamkyong, from where most of the migrants originated.

  15. Language and Family Dispersion: North Korean Linguist Kim Su-gyŏng and the Korean War

    Directory of Open Access Journals (Sweden)

    Ryuta Itagaki

    2017-03-01

    Full Text Available This article analyzes the unpublished memoir of Kim Su-gyŏng (1918–2000, a linguist who was active in North Korea from the mid-1940s until the late 1960s, and situates his account of his experience of the Korean War within the context of his linguistic essays and correspondence. In doing so, the article considers the role that the personal and the social play in language, utilizing Saussure’s theoretical framework, with which Kim himself was well versed. Kim wrote his memoirs in the 1990s to his family, from whom he had become separated during the Korean War and who now lived in Toronto. In this text, he writes in “personal” language that reveals his uncertainty and his feelings for his family, but then immediately negates these feelings through the use of “social” language, which resonates with his interpretation of the linguistic thesis that Josef Stalin developed during the Korean War on language and national identity. For Kim, the relationship between language and nation was not at all self-evident, but something that he idealized in response to the dispersal of his family. By offering a reflexive reading of a memoir written by a North Korean linguist, this article makes a breakthrough in the investigation of North Korean wartime academic history, which has not risen above the level of analyzing articles in the field of linguistics that were published at the time.

    The number of North Korean refugees entering South Korea has increased recently. The health status of refugees is a significant factor in determining their success in resettlement; therefore, this study examined both the self-rated health status of North Korean defectors who have settled in South Korea and the factors associated with their self-rated health status. This study utilized data gained from face-to-face interviews with 500 North Korean defectors who arrived in South Korea in 2007. The interviews were structured and conducted by 'Yonsei University Research Team for North Korean defectors'. A stepwise multivariable linear regression was performed to determine the factors associated with their self-rated health status. North Korean defectors who were female, elderly, or had low annual household income, disability or chronic diseases reported lower health status. However, self-rated health status was higher among those who had settled in South Korea for 18 months or more, who were satisfied with government support or their current life, and who had experienced more traumatic events in North Korea. Government policies and refugee assistance programs should consider and reflect the factors relevant to the health status of North Korean defectors.

    This study aimed to investigate North Korean refugees' knowledge of mental illnesses and treatments and analyze the factors affecting this knowledge. Subjects were selected via a snowball sampling method, and the survey outcomes of 152 North Korean refugee participants were analyzed. The factors affecting knowledge of mental illnesses were analyzed via a regression analysis by constructing a multivariate model with mental illness knowledge score as the dependent variable. The North Korean refugees' mental illness scores ranged from 3 to 24 points, with an average score of 13.0. Regarding the factors that influence mental illness knowledge, the subjects with South Korean spouses and those who had spent more time in South Korea had higher knowledge scores. Furthermore, the subjects who considered the mental health of North Korean refugees to be a serious issue revealed lower knowledge scores than those who did not believe it was a serious issue. The subjects who visit psychiatric clinics showed higher knowledge scores than those who do not. The South Korean subjects who had at least a college education exhibited higher scores than did those without advanced education. The subjects who are satisfied with life in South Korea manifested a higher mental illness knowledge score than those who are not. This study is significant as being the first study to ever measure and evaluate the level of North Korean refugees' knowledge of mental illnesses. In addition, the evaluations of North Korean refugees' mental illness knowledge and influencing factors while residing in South Korea created basic data that formed the foundation of an effort to enhance mental health literacy and provide proper mental health services. The results of this study can be utilized to solve mental health problems that might frequently occur during the unification process of North and South Korea in the future.

    Schwekendiek, Daniel J

    2017-04-01

    This paper investigates the trend in height among adult Korean orphans who were adopted in early life into affluent Western nations. Final heights of 148 females were analyzed based on a Korean government survey conducted in 2008. Height of the orphans was descriptively compared against final heights of South and North Koreans. Furthermore, statistical determinants of orphan height were investigated in multivariate regressions. Mean height of Korean orphans was 160.44 cm (SD 5.89), which was higher than that of South Koreans at 158.83 cm (SD 5.01). Both Korean orphans and South Koreans were taller than North Koreans at 155.30 cm (SD 4.94). However, height of Korean orphans stagnated at around 160-161 cm while those of North and South Koreans improved over time. In the regression analysis, the socioeconomic status of the adoptive family was statistically significant in all models, while dummies for the adoptive nations and age at adoption were insignificant. This study shows that the mean final height of women experiencing extreme environmental improvements in early-life is capped at 160-161 cm, tentatively suggesting that social stress factors in the host nation or early-life factors in the birth nation might have offset some of the environmental enrichment effects achieved through intercountry adoption.

    2007-10-01

    North Korea's nuclear weapon development is a serious threat to South Korea's national security and can become a trigger to change the status quo in the Korean peninsula. Having prevailed security dynamics in Northeast Asia last 20 years, the North Korea's nuclear problem faced a key turning point when Pyongyang tested its first nuclear weapon on October 9, 2006. Despite this test, however, diplomatic efforts to resolve the nuclear issue were never given up, resulting in a so-called, initial agreement signed at the Six-Party Talks in February 2007. With the Six-Party Talks being held more than four years, the six countries have had sufficient time to discuss principal and political matters regarding the dismantlement of North Korea's nuclear weapons. Under the circumstances, this report is going to study practical and detail issues related with dismantling the North's nuclear weapons. Specifically, in light of historical experiences, the report will investigate possible problems to be faced in the course of dismantlement and propose policy measures to overcome these problems

    Lack of medical care in North Korea and vulnerability to human trafficking during their migration increase risks of cervical cancer among North Korean refugees. To better understand factors influencing Pap test use, we conducted a qualitative study of eight North Korean refugees in South Korea. Individual barriers were limited knowledge, lack of perceived need for preventive services, and concerns about costs. Environmental facilitators included having female providers, receiving family support, and free screenings. Refugees' health outlook, including viewing cancers as fatal diseases, hindered seeking Pap tests. Multi-faceted approaches to address individual and environmental factors in promoting Pap tests are warranted.

The study examines as an indicator the number of papers in the JKNS and NET that have been cited by KAERI researchers in the SCI Source Journal (to the end of August 2006). This paper also gives a review of the statistics provided by the Institute for Scientific Information (ISI), as an authoritative source for an evaluation of a global cataloguing of scientific and technical journals, and suggests a view for a listing of the Korean nuclear journals in the SCI by a review of associated selection criteria and methods. It concludes there is a need to increase the number of citations in the SCI source journals of the NET papers to be published from the most recent previous two years

    This paper describes the outstanding performance of the indigenous development program of nuclear power technology such as the design and fabrication of both CANDU and PWR fuel and in the design and construction of nuclear steam supply system in Korea. The success has been accomplished through the successful technology transfer from foreign suppliers and efficient utilization of R and D manpower in the design and engineering of nuclear power projects. In order to implement the technology transfer successfully, the joint design concept has been introduced along with effective on-the-job training and the transfer of design documents and computer codes. Korea's successful development of nuclear power program has resulted in rapid expansion of nuclear power generation capacity in a short time, and the nuclear power has contributed to the national economy through lowering electricity price by about 50 % as well as stabilizing electricity supply in 1980s. The nuclear power is expected to play a key role in the future electricity supply in Korea. Now Korea is under way of taking a step toward advanced nuclear technology. The national electricity system expansion plan includes 18 more units of NPPs to be constructed by the year 2006. In this circumstance, the country has fixed the national long-term nuclear R and D program (lgg2-2001) to enhance the national capability of nuclear technology. This paper also briefly describes future prospects of nuclear technology development program in Korea

    Many studies on refugees suggested that refugees' traumatic events associated with post-traumatic stress disorder (PTSD). However, it is unknown whether refugees' PTSD was caused by their negative experience before or after the entry of their destination country. Thus, a separation of refugees' pre-migration from their post-migration experience is particularly important in understanding the causal impact of trauma. Using a sample from North Korean refugees, this study investigates the prevalence of PTSD symptoms, the impact of tortured trauma, repatriation experiences, on PTSD among North Korean refugees (n = 698). We found that North Korean refugees in our sample (a) demonstrated a high rate of current probable PTSD; (b) were demonstrated a higher frequency of repatriation experiences with a greater risk for PTSD symptoms. The findings suggest that particular types of trauma for populations with particular socio-demographic characteristics may be at a greater risk of PTSD.

    The system analysis for Korean nuclear power reactor option is made on the basis of reliability, cost minimization, finite uranium resource availability and nuclear engineering manpower supply constraints. The reference reactor scenarios are developed considering the future electricity demand, nuclear share, current nuclear power plant standardization program and manufacturing capacity. The levelized power generation cost, uranium requirement and nuclear engineering professionals demand are estimated for each reference reactor scenarios and nuclear fuel cycle options from the year 1990 up to the year 2030. Based on the outcomes of the analysis, uranium resource utilization, reliability and nuclear engineering manpower requirements are sensitive to the nuclear reactor strategy and associated fuel cycle whereas the system cost is not. APWR, CANDU: FBR strategy is to be the best option for Korea. However, APWR, CANDU: Passive Safe Reactor (PSR) vFBR strategy should be also considered as a contingency for growing national concerns on nuclear safety and public acceptance deterioration in the future. FBR development and establishment of related fuel cycle should be started as soon as possible considering the uranium shortage anticipated between 2007 and 2032. It should be noted that the increasing use of nuclear energy to minimize the greenhouse effects in the early 21st century would accelerate the uranium resource depletion. The study also concludes that the current level of nuclear engineering professionals employment is not sufficient until 2010 for the establishment of nuclear infrastructure. (Author)

    Given previous research on depression, history of physical abuse, family order, attachment, and parenting, we hypothesized that the physical abuse-depression relationship would be moderated by (a) family order and (b) attachment, and that (c) attachment and family order would interact significantly in predicting depression. Hypotheses were tested in South Korea in a random cluster sample of 82 youth aged 15-25 who were either themselves North Korean refugees (n=39) or who were born to North Korean refugee mothers in China (n=43). A qualitative interview was used to shed further light on the findings. Family order appears to be a protective factor against depression in that more order is associated with a weakened past abuse-depression relationship. Copyright © 2015 Elsevier Ltd.

    1997-01-01

    Korea has carried out a very ambitious nuclear power program since the 1970's as part of the nation's industrialization policy. Ever since, Korea has also maintained a strong commitment to nuclear power development as an integral part of the national energy policy which aims at reducing external vulnerability and ensuring against a global fossil fuel shortage. The introduction of nuclear power into Korea has progressed through three stages: the first was a turn-key package supplied by the manufacturer; the second involved a major contractor who was responsible for project management, and design and construction was contracted out, with Korean industry becoming more involved; the third stage has seen Korean industries involved as main contractors based on experience gained from earlier plants. The success of Korea's nuclear power program depends in large part on how to insure safety. Safety has the highest priority in nuclear energy development. Public acceptance has been the most critical problem faced by the nuclear industry in Korea. The public demands the highest level of safety all through the design, construction, and operation of nuclear power plants. Korea has learned that a nuclear plant designed with well addressed safety, implementation of a well grounded QA program during construction, and operated with a proven record of safety, are the only ways to earn public support. Competent and efficient regulation with a strong safety culture and openness in all issues is the most desirable image for regulators to strive for. Korea established a ten year R ampersand D program to obtain self-reliance in nuclear technology and international competitiveness by the early 2000's in 1992. It has actively participated in coordinated research programs in safety issues with bodies including the USNRC, AECB of Canada, IAEA, and OECD/NEA

    Post-traumatic stress disorder is common among North Korean refugees who have fled their country for economic, financial and humanitarian reasons. Co-morbid depression and anxiety are also common among North Korean refugees, due to the difficulties they have faced within their country and during their escape journey. Depression and anxiety complicate treatment for post-traumatic stress disorder, and lead to poorer outcomes. Thus, the aim of the present study was to provide a meta-analysis of studies investigating post-traumatic stress disorder, depression, and anxiety among North Korean refugees. Selected articles were published in English, and included measures of post-traumatic stress, and/or depression and anxiety. 10 studies were included in the depression meta-analysis, and 6 in the anxiety meta-analysis. A random-effects model revealed strong, significant associations between post-traumatic stress and depression, r=0.63, 95% CI (0.51, 0.72), pstress, depression and anxiety were higher among adults and those with more than five years outside of North Korea. Depression appears to be an important treatment focus for North Korean refugees with post-traumatic stress.

    Full Text Available As a result of conducting a 45 minute-long seminar on the principles, state of use, advantages, and disadvantages of nuclear power generation for Korean elementary, middle, and high school students, the levels of perception including the necessity (p<0.017, safety (p<0.000, information acquisition (p<0.000, and subjective knowledge (p<0.000, objective knowledge (p<0.000, attitude (p<0.000, and behavior (p<0.000 were all significantly higher. This indicates that education can be effective in promoting widespread social acceptance of nuclear power and its continued use. In order to induce behavior change toward positive judgments on nuclear power generation, it is necessary to focus on attitude improvement while providing the information in all areas related to the perception, knowledge, attitude, and behavior. Here, the positive message on the convenience and the safety of nuclear power generation should be highlighted.

    While literature on elder abuse has expanded, elder abuse by intimate partners has been less investigated. Even less is known about intimate partner violence among older Koreans living in North America. This article identifies important cultural considerations for individuals helping the Korean older adult community, beginning with the definition of intimate partner violence in this community and barriers to leaving that include traditional views of the East Asian self. Current practice interventions are discussed and recommendations for future practice such as healing han, the accumulated suffering from years of abuse, are suggested. The ultimate goal of this paper is to expand awareness in order to develop the best culturally competent prevention and intervention practice for Korean older intimate partner violence survivors in North America.

    As the application of nuclear medicine to clinics became generalized and it held an important position, the Korean Society of Nuclear Medicine was founded in 1961, and today it has become known as one of the oldest nuclear medicine societies not only to Asian nations but also to other advanced countries all over the world. Now it has 100 or so regular members composed of students of each medicine filed unlike other medical societies. Only nuclear medicine research workers are eligible for its membership. The Korean Society of Nuclear Medicine holds its regular general meeting and symposium twice per annom respectively in addition to occasional group gatherings and provincial lectures on nuclear medicine. With an eye to exchanging information on symposium, research and know-how, KSNM issued its initial magazine in 1967. Every year two editions are published. Year after year the contents of treatises are getting elevated with researches on each field including the early study on morphology-greatly improved both in quality and quantity. Of late, a minute and fixed quantity of various matters by dynamical research and radioimmunoassay of every kind has become visibly active. In particular, since KSNM, unlike other local societies, keeps close and frequent contact with the nuclear medicine researchers of world-wide fame, monographs by eminent scholars of the world are carried in its magazine now internationally and well received in foreign countries. Now the magazine has been improved to such an extent that foreign authors quote its contents. KSNM invited many a foreign scholar with a view to exchanging the knowledge of nuclear medicine. Sponsored by nuclear energy institute, the nuclear medicine symposium held in Seoul in October of 1966 was a success with Dr. Wagner participating, a great scholar of world wide fame: It was the first international symposium ever held in Korea, and the Korea Japan symposium held in Seoul 1971 was attended by all distinguished nuclear

    Korea began to nurture its nuclear energy pioneers in the 1950s when the government dispatched personnel in research and policy-making areas to foreign institutions. Then in 1959, KAERI was established and now plays a leading role in nuclear technology R and D. In addition, Korea's first research reactor, TRIGA Mark-II, was built and put into operation in 1962. This paved the way for advancements in operation and technical development of nuclear reactors. In turn, these accomplishments led to the birth of Korea's first commercial reactor, Kori Unit 1, in the 1970s, and HRD in the nuclear industry was put on the right track. However, the Korean nuclear industry remained heavily dependent on nuclear exporting countries such as the US, Canada, and France. Already confident in construction, Korea took the lead in building Kori Units 3 and 4 and Ulchin Units 1 and 2 in the 1980s, but the country was still in need of technological self-reliance. In order to achieve this, Korea proactively launched systematic HRD programs and dispatched nuclear professionals to overseas nuclear facilities to secure individuals competent in the areas of NPP operations, plant design, and major equipment manufacturing. Thanks to its diligent endeavors, Korea's nuclear entities established independent nuclear training institutes in the 1990s and began producing a large number of competent personnel. This allowed the country to ensure not only the best operation and maintenance engineers but also the essential nuclear technology required for plant design and equipment manufacturing. Since the beginning of the 21{sup st} century, Korea has been producing its nuclear personnel on its own and exchanging nuclear training instructors and trainees with other organizations in fields where specialized knowledge is needed. Furthermore, Korea is taking comprehensive nuclear HRD measures in response to the rising demand for human resources that result from ongoing construction of NPPs in

    Successful adaptation of refugees to a new society can be hindered by traumatic experiences and psychiatric symptoms. This study aims to examine the relationship between trauma, psychiatric symptoms and life satisfaction of North Korean refugees resettled in South Korea. A total of 211 North Korean refugees living in South Korea completed a series of questionnaires on the history of their previous traumatic experiences, life satisfaction in South Korea, depression, anxiety, somatization and post-traumatic stress disorder (PTSD) symptoms. North Korean refugees who had experienced more traumatic events were less satisfied with their economic status in South Korea. Severe depression, anxiety, somatization or PTSD symptoms negatively correlated with their overall satisfaction in South Korea. In the stepwise regression model including all psychiatric symptoms and the number of traumatic experiences as dependent variables, only anxiety, but not trauma, predicted lower life satisfaction in South Korea. Traumatic experiences of North Korean refugees negatively affected the life satisfaction, especially the economic satisfaction, in South Korea. Since the negative effect of trauma was mainly mediated by psychiatric symptoms, the strategy of relieving psychiatric symptoms of traumatized refugees may help the adaptation of refugees. © 2017 S.

    Full Text Available North Korean refugees experience adaptation difficulties, along with a wide range of psychological problems. Accordingly, this study examined the associations between early traumatic experiences, negative automatic thoughts, and depression among young North Korean refugees living in South Korea. Specifically, we examined how different factors of negative automatic thoughts would mediate the relationship between early trauma and depressive symptoms. A total of 109 North Korean refugees aged 13–29 years were recruited from two alternative schools. Our path analysis indicated that early trauma was positively linked with thoughts of personal failure, physical threat, and hostility, but not with thoughts of social threat. The link with depressive symptoms was only significant for thoughts of personal failure. After removing all non-significant pathways, the model revealed that early traumatic experiences were positively associated with depressive symptoms (ß = 0.61, 95% CI = 0.48–0.73 via thoughts of personal failure (ß = 0.17, 95% CI = 0.08–0.28, as well as directly (ß = 0.44, 95% CI = 0.27–0.59. Interventions that target negative cognitions of personal failure may be helpful for North Korean refugees at risk of depression.

    This study investigated the mediation effect of stress between the experience of discrimination and life satisfaction among North Korean refugees who resettled in South Korea. The findings of the current study provide empirical evidence for the need of social interventions to mitigate adverse effects of stress on North Korean refugees who are subject to social discrimination on a daily basis. In this study, we included 500 subjects among 2,138 North Korean refugees who took refuge in South Korea in 2007. The interview started from April 6th 2009 and finished on May 25th 2009. We conducted moderator effect analysis with Path analysis was conducted because we confirm the experience of discrimination was affected by life satisfaction and stress can affected life satisfaction as a moderator. The experience of discrimination significantly affects stress and stress significantly affects life satisfaction. However, the experience of discrimination was not directly related to life satisfaction. The more stress the study respondents experienced, the lower the life satisfaction they reported. The present finding suggests that the effects of discriminating experiences on the life satisfaction of North Korean refugees in South Korea were mediated by their own perceived stress.

    This study examined the heterogeneity in the Minnesota Multiphasic Personality Inventory-2nd Edition (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) profiles of North Korean female refugee population (N = 2,163) using latent profile analysis (LPA). The North Korean female refugee sample arrived at Hanawon, South Korea's resettlement center for North Korean refugees in 2008 and 2009 and took the MMPI-2 as part of an initial psychological screen. The analysis, which included the T scores of the 6 validity scales and the 10 standard clinical scales, identified 4 classes with distinctive psychological features: Class 1 (nonclinical), Class 2 (demoralized), Class 3 (somatized), and Class 4 (detached). The 4 covariates entered into the model (age, education, affiliation with a religion, and the number of forced repatriations) impacted the likelihood of belonging to certain classes. As hypothesized, older age, fewer years of education, and more incidents of forced repatriation predicted higher proneness to psychopathology. However, contrary to our expectation, having a religious faith did not emerge as a salient protective factor. The current LPA results revealed distinct heterogeneous subgroups that previous research on the MMPI and MMPI-2 profiles of refugee populations overlooked with the assumption of a homogeneous sample. Clinical implications for the treatment of North Korean female refugees and the limitations of the study are discussed. (c) 2013 APA, all rights reserved.

    Although the prevalence of depressive disorders among North Korean (NK) refugees living in South Korea has been reported to be twice the rate of their South Korean counterparts, little is known about the correlates of depressive symptoms among this population. Despite their escape from a politically and economically repressive setting, NK refugees continue to face multidimensional hardships during their adaptation process in South Korea, which can adversely affect their mental health. However, to our knowledge, no empirical research exists to date on depressive symptoms in the context of adaptation or perceived discrimination among NK refugees. To fill this gap, this study used a sample of 261 NK refugees in South Korea from the 2010 National Survey on Family Violence to examine associations between sociocultural adaptation, perceived discrimination, and depressive symptoms, as well as the moderation effect of discrimination on adaptation to depressive symptoms. We found that poor sociocultural adaptation and perception of discrimination were associated with increased levels of depressive symptoms. Perception of discrimination attenuated the association between better adaptation and fewer depressive symptoms, when compared to no perception of discrimination. These findings highlight the need to improve NK refugees' adaptation and integration as well as their psychological well-being in a culturally sensitive and comprehensive manner. They also underscore the importance of educating South Koreans to become accepting hosts who value diversity, yet in a homogeneous society. Copyright © 2015 Elsevier Ltd. All rights reserved.

    theory is that depreciation in the value of the Canadian dollar relative to the U.S. dollar should cause some migrants to substitute Canada for the United States as their destination of choice. Using data on Korean immigration to Canada and the United States, we estimate a regression model to test this hypothesis. The statistical evidence strongly supports a conclusion that exchange rate movements can cause some migrants to substitute destinations.

    Korea Institute of Nuclear Nonproliferation and Control (KINAC) has prepared the regulatory standard RS-015 based on RG 5.71. RS-015 defines the elements of a cyber security program to be established in nuclear facilities and describes the security control items and relevant requirements. Cyber security assessments are important initial activities in a cyber security program for NPPs. Cyber security assessments can be performed in the following key steps: 1) Formation of a cyber security assessment team (CSAT); 2) Identification of critical systems and critical digital assets (CDAs); 3) Plant compliance checks with the security control requirements in RS-015. Through the assessments, the current status of security controls applied to NPPs can be found out. The assessments provide baseline data for remedial activities. Additional analyses with the results from the assessments should be performed before the implementation of remedial security controls. The cyber security team at the Korea Atomic Energy Research Institute (KAERI) has studied how to perform cyber security assessments for NPPs based on the regulatory requirements. Recently, KAERI's cyber security team has performed pilot cyber security assessments of a Korean NPP. Based on this assessment experience, considerations and checkpoints which would be helpful for full-scale cyber security assessments of Korean NPPs and the implementation of remedial security controls are discussed in this paper. Cyber security assessment is one of important and immediate activities for NPP cyber security. The quality of the first assessment will be a barometer for NPP cyber security. Hence cyber security assessments of Korean NPPs should be performed elaborately

The cyber security team at the Korea Atomic Energy Research Institute (KAERI) has studied how to perform cyber security assessments for NPPs based on the regulatory requirements. Recently, KAERI's cyber security team has performed pilot cyber security assessments of a Korean NPP. Based on this assessment experience, considerations and checkpoints which would be helpful for full-scale cyber security assessments of Korean NPPs and the implementation of remedial security controls are discussed in this paper. Cyber security assessment is one of important and immediate activities for NPP cyber security. The quality of the first assessment will be a barometer for NPP cyber security. Hence cyber security assessments of Korean NPPs should be performed elaborately.

    The rapid climate changes and the heavy reliance on imported fuel in Korea have motivated interest in the hydrogen economy. The Korean government has set up a long-term vision for transition to the hydrogen economy. To meet the expected demand of hydrogen as a fuel, hydrogen production using nuclear energy was also discussed. Recently the Korean Atomic Energy Committee has approved nuclear hydrogen production development and demonstration which will lead to commercialisation in late 2030's. An extensive research and development programme for the production of hydrogen using nuclear power has been underway since 2004 in Korea. During the first three years, a technological area was identified for the economic and efficient production of hydrogen using a VHTR. A pre-conceptual design of the commercial nuclear hydrogen production plant was also performed. As a result, the key technology area in the core design, the hydrogen production process, the coupling between reactor and chemical side, and the coated fuel were identified. During last three years, research activities have been focused on the key technology areas. A nuclear hydrogen production demonstration plant (NHDD) consisting of a 200 MWth capacity VHTR and five trains of water-splitting plants was proposed for demonstration of the performance and the economics of nuclear hydrogen. The computer tools for the VHTR and the water-splitting process were created and validated to some extent. The TRISO-coated particle fuel was fabricated and qualified. The properties of high temperature materials, including nuclear graphite, were studied. The sulphur-iodine thermochemical process was proved on a 3 litre/ hour scale. A small gas loop with practical pressure and temperature with the secondary sulphur acid loop was successfully built and commissioned. The results of the first phase research increased the confidence in the nuclear hydrogen technology. From 2009, the government decided to support further key technology

    Korea has been maintaining efficient and systematic State System for Accounting and Control of nuclear materials (SSAC) for elevation of our nuclear transparency and reliability to international society. So far, Korean SSAC had been considered as a good example of SSAC together with Euratom, Japan, ABACC. But, owing to changing environment such as a series trial due to the KAERI's past nuclear material experiments, strengthened international nonproliferation scheme, advent of integrated safeguards and technology development in nuclear fields, voices of demand for changes in Korean SSAC are being brought up. Therefore, this study grasped and analyzed international nuclear environment and direction of changes in nuclear control regime, besides re-examine the roles of Korean SSAC and proposed the direction where Korean SSAC should be shifted

    Childhood immunization rates are at an all-time high globally, and national data for China suggests close to universal coverage. Refugees from North Korea and their children may have more limited health care access in China due to their legal status. However, there is no data on immunization rates or barriers to coverage in this population. This study was conducted to determine the rates and correlates of immunizations in children (≥1 year) born to North Korean refugees in Yanbien, China. Child immunization data was obtained from vaccination cards and caregiver self-report for 7 vaccines and 1:3:3:3:1 series. Age-appropriate vaccination rates of refugee children were compared to Chinese and migrant children using a goodness-of-fit test. Logistic regression was used to determine correlates of immunization coverage for each vaccine and the 1:3:3:3:1 series. Age-appropriate immunization coverage rates were significantly lower in children born to North Korean refugees (12.1-97.8 %), compared to Chinese (99 %) and migrant (95 %) children. Increased father's age and having a sibling predicted significantly lower vaccination rates. Children born to North Korean refugees had significantly lower immunization rates, compared to Chinese or migrant children. Further research is needed to examine barriers of health care access in this high-risk population.

    The Korean government promulgated the 4th Comprehensive Nuclear Energy Promotion Plan (CNEPP) in November 2011, which included the objectives and strategies with the overriding priority that the Korean government and nuclear institutes should carry forward to achieve over next 5 years. Since 1997, when the first CNEPP was promulgated, the Korean government has modified and supplemented the CNEPP every 5 years based on an analysis of the outcomes of the previous CNEPP as well as the outlook on the future nuclear energy uses and developments in domestic and foreign countries. This paper reviews the history of the CNEPP and gives a general idea of the 4th CNEPP. (orig.)

    The current study investigated the burnout and secondary traumatic stress of service providers for North Korean (NK) refugees based on the conceptual framework of theJob Demands-Resources (JD-R) model of workplace burnout. A cross-sectional self-administered survey was conducted with a national sample consisting of all 63 organizations in direct services to North Korean refugees. Of the estimated total number of 230 service providers comprising of social workers, psychotherapists, job counselors and paraprofessional counselors, 179 completed the survey, a 77.8% return rate. While job resources such as personal commitment to work and organizational support indicated inverse relations to burnout, job demands such as workload, work environment and secondary traumatic stress (STS) showed a positive relationship to worker burnout. The STS were present in more than half of the respondents (51.3%), of which 20.7% of them indicating a severe level of STS. The STS proved to be the most significant risk to worker burnout as it showed strong relations to all three dimensions of burnout. Structural issues of chronic work overload and poor work environment need to be addressed to reduce staff burnout. STS is a serious occupational hazard in working with North Korean refugees.

    After having recalled the various resolutions issued by the UN Security Council to implement sanctions against North Korea after its nuclear and ballistic tests, the author comments the content of the last report issued by the group in charge of the implementation of resolutions number 1718 (of 2006) and 1874 (of 2009). The report first highlights the continuing efforts of North Korea in the nuclear and ballistic fields. These efforts are institutional and legal as well as practical with the construction of new installations and test sites as revealed by satellite images. They also have been studied with the examination of debris of a North-Korean rocket. Apart from that, the report described and outlined how North Korea remains an important actor of the trade of proliferation equipment. Recommendations made by the expert group are commented: they notably outline that the implementation of sanctions is complex and incomplete for various reasons related either to North Korean actions and behaviours, or to the process itself

  7. Savage Nature and Noble Spirit in Han Sorya's Wolves: A North Korean Morality Tale

    2012-05-01

    Full Text Available Peer reviewed article. This paper is a narratological study of Han Sorya's Wolves, a canonical novelette in the tradition of North Korean socialist realism that has been adjudicated outside North Korea as anti-American, anti-Christian, and extremely racist. The novelette, however, is a more metaphorical, hybrid, and complicated piece of writing than has previously been assumed. Descriptive and interpretative narratological analysis reveals that Wolves is a patriotic-proletarian morality tale against colonialism, imperialism, racism, and war. The story also reveals grand metaphysical and normative Neo-Confucian imperatives, which operate as moral shaping principles that are interwoven into character, plot, and theme.

    A comprehensive settlement of the North Korean nuclear issue may involve military, economic, political, and diplomatic components, many of which will require verification to ensure reciprocal implementation. This paper sets out potential verification methodologies that might address a wide range of objectives. The inspection requirements set by the International Atomic Energy Agency form the foundation, first as defined at the time of the Agreed Framework in 1994, and now as modified by the events since revelation of the North Korean uranium enrichment program in October 2002. In addition, refreezing the reprocessing facility and 5 MWe reactor, taking possession of possible weapons components and destroying weaponization capabilities add many new verification tasks. The paper also considers several measures for the short-term freezing of the North's nuclear weapon program during the process of negotiations, should that process be protracted. New inspection technologies and monitoring tools are applicable to North Korean facilities and may offer improved approaches over those envisioned just a few years ago. These are noted, and potential bilateral and regional verification regimes are examined.

    Nuclear energy has been a backbone for Korea's remarkable economic growth, and will continue its essential role with 18 nuclear power plants in operation, 2 more units under construction, 6 more units in planning. Korea is operating its own designed nuclear power plants, such as KSNP, 1400, as well as self-design and operation of 30 MW Hanaro research reactor. Korea makes strong efforts to develop future nuclear technology. They are the System-Integrated Modular Advanced Reactor, SMART, Korea Advanced Liquid Metal reactor, KALIMER, Hydrogen Production reactor, and Proliferation-resistant Nuclear Fuel Cycle. In parallel, Korea is establishing an Advanced Radiation Technology R and D Center and a High Power Proton Accelerator Center. International, next generation nuclear power technologies are being developed through projects such as the IAEA Innovative Nuclear Reactors and Fuel Cycle, INPRO, Generation IV International Forum, GIF, and International thermonuclear Experimental reactor, ITER. In the new millennium, Korea expects that radiation technology combined with bio, nano, and space technology will sustain our civilization. About 21,000 qualified nuclear human resources are engaged in power and non-power fields such as design and manufacturing of equipment, plant operation and maintenance, safety, RI production, R and D, etc. However, it is recognized that the first generation of nuclear work force is getting older and retired, less of our youth are studying nuclear science and engineering. Korean Government has established a promotion program on nuclear human resources development, which is needed until 2010. For the sustainable development of nuclear science and technology, it calls for more qualified human resources. We ought to encourage our youth to become more interested in nuclear studies and careers. Korea is making strong efforts to support nuclear education and training for young generations. It is believed that internationally accepted advanced

    For Korea, it is essential to participate in the decommissioning of North Korean nuclear facilities for Pu-based weapon program and to lead the project for the protection of the environments from the possible spread of nuclear contamination. Before, the studies for the verification of the North Korea nuclear facilities and for the technical preparation of the decommissioning of north Korea were conducted but the depth of the studies was not reached to the evaluation of the decommissioning project by the documentation of a decommissioning plan to the provision of the technical information to the policy decision makers. It is very helpful for understanding the characteristics of the decommissioning projects to formulate a possible dismantling scenario and to make a decommissioning plan. The cost and the periods estimated on the base of this scenario is more exact and the analysis for the selection of different policies will be possible

  15. Reconstructing the public in old and new governance: a Korean case of nuclear energy policy.

    2014-04-01

    Korean nuclear energy regulatory policies started to change from earlier exclusively technocratic policies into open dialogues after several anti-nuclear protests in the 1990s. However, technocratic policies still coexist with the new regulatory orientation towards openness, participation and institutional accountability. This paper analyzes Korean nuclear regulatory policies since approximately 2005 as a blend of old and new governance. The aim of the paper is not to decide whether new nuclear governance is deliberative or not by completely reviewing Korean nuclear policies after the 2000s. Instead, it provides an empirical account of how seemingly more participatory processes in decision-making entail new problems while they work with and reproduce social assumptions of different groups of the public.

    The number of North Korean adolescent defectors entering South Korea has been increasing. The health behavior, including mental health-related behavior, and factors associated with depression in North Korean adolescent defectors residing in South Korea were investigated. Data obtained from the Korea Youth Risk Behavior Web-Based Survey (2011-2014) dataset were utilized. In total, 206 North Korean adolescent defectors were selected, and for the control group, 618 matched South Korean adolescents were selected. Frequency analysis was used to determine the place of birth and nationality of the parents, chi-square tests were used to compare the general characteristics of the North and South Korean subjects, and multivariate logistic regressions were conducted to compare the health behavior of the two sets of subjects. To determine the factors associated with depression in the North Korean subjects, a logistic regression was performed. The North Korean adolescents reported higher current smoking (adjusted odds ratio [aOR], 2.54; 95% confidence interval [CI], 1.48 to 4.35), current drinking (aOR, 1.85; 95% CI, 1.15 to 2.99), and drug use rates (aOR, 10.99; 95% CI, 4.04 to 29.88) than did the South Korean adolescents. The factors associated with depression in the North Korean adolescents were current smoking (aOR, 6.99; 95% CI, 1.62 to 30.06), lifetime drinking experience (aOR, 5.32; 95% CI, 1.51 to 18.75), and perceived stress (aOR, 4.74; 95% CI, 1.74 to 12.90). There were differences in health behavior between the North and South Korean adolescents. A specialized approach for North Korean adolescent defectors is required to promote proper health behavior and adaptation to South Korean society.

Unfortunately, wireless technologies are not currently installed in any Korean NPPs because it is difficult to solve the negative impact of unexpected outcomes or failures from the influence of the wireless technologies, which is electromagnetic interference and radio-frequency interference (EMI/RFI). Moreover, a lack of desire on the part of Korean nuclear industry to implement it leads to give up benefit from the wireless technologies. To install the wireless technologies with maximum benefit and minimum risk, a systematic approach, which quantify the negative impact and prevent the influence, is essential; therefore, this paper describes an applicable research result on the wireless technology for Korean NPPs based on regulatory guides and current wireless hardware and software technologies. Also, survey on the needs for the wireless technology for Korean nuclear power plants was conducted, because the level of awareness of workers in NPPs regarding wireless technologies is very important issue. In this paper, we propose an applicable system to enhance the applicability for the wireless technology for Korean NPPs. The result based on proposed applicable system shows that wireless local area network (WLAN) is the representative candidate for Korean NPPs, which can be applied to the specific fields of radiation monitoring, voice and data communication, component monitoring and instrumentation, and wireless cameras

    2016-01-01

    As North Korea announced a successful test for its first hydrogen nuclear bomb, the author first recalls the origins of the Korean conflict, and then presents the North Korean nuclear weapon programme as a result of a sense of insecurity for the North Korean regime, notably after the collapse of USSR. The nuclear weapon then became a priority and the programme has been rather quickly developed, probably with the help of the father of the Pakistani bomb. A first and second plutonium-based bombs have been tested, and then an enriched uranium-based bomb, and lastly, in January 2016, a hydrogen bomb. Doubts about this achievement are evoked. Then, the author proposes a brief overview of negotiations with the USA, and outlines the problematic behaviour of North Korea regarding the regional situation in an evolving context: a stronger Chinese economy, change in China's position towards North Korea, and Japan re-militarization

    Full Text Available This paper examines the problem of the intentional fallacy in the North Korean short story 'First Meeting' by Kim Hye-yong. Serially published in Korea Today in 2007, the nationalist allegory centres on Shin Ch'ong-mi, a young female journalist in Pyongyang, who falls in love with her penfriend Song-u, a soldier in the Korean People's Army, and struggles to remain devoted to him when he suddenly stops writing. With the literary-critical method of counterintuitive reading, the inquiry analyses the structural relations of the narrative, its discourse on desire, its apparent intentions, and its contravening elements, revealing an incidental unstable narrative that is symbolically protesting of the moral of the story to affectionately embrace the political authority of the North Korean party-army regime in the military-first (songun era.

    The energy supply optimization model MESSAGE-III is improved to evaluate the role of nuclear energy system in Korean long-term energy supply strategy. Emphasis is placed on the potential contribution of nuclear energy in case of environmental constraints and energy resource limitation. The time horizon is 1993-2040. A program to forecast useful energy demand is developed, and optimization is performed from the overall energy system to the nuclear energy system. Reactor and fuel cycle strategy and the expanded utilization options for nuclear energy system are suggested. FBRs, HTGRs and thorium fuel cycle would play key roles in the long run. The most important factors for nuclear energy in Korean energy supply strategy would be the availability of fossil fuels, CO 2 reduction regulation, and the supply capability of nuclear energy.

    A realistic approach to North-South arms control and disarmament would require a step-by-step formula encompassing measures for political and military confidence building, arms limitation and reduction. The most fundamental and important condition for achieving meaningful results in disarmament talks is securing political and military confidence. The problem which arose on the Korean peninsula originates from relations of North Korea and IAEA. North Korean position poses a serious threat to the Non-proliferation Treaty, in particular to the IAEA Safeguards regime. Nuclear non-proliferation and the ultimate elimination of nuclear weapons are the primary concerns of the post-cold war era. The Government of South Korea hopes that this issue can be solved through dialogue and negotiations

    In complex emergencies, especially those involving famine and/or widespread food insecurity, assessments of malnutrition are critical to understanding the population's health status and to assessing the effectiveness of relief interventions. Although the Democratic People's Republic of Korea (DPRK) has benefited from some of the largest, most sustained appeals in the history of the World Food Program (WFP), the government in Pyongyang has placed restrictions on international efforts to gather data on the health and nutritional status of the affected population. Lacking direct means to assess the nutritional status of the North Korean populace, what other methodologies could be employed to measure the public health impacts of chronic food shortage? The paper begins with a review of methods for assessing nutritional status, particularly in emergencies; a brief history of the North Korean food crisis (1995-2001), and a review of the available nutritional and health data on the DPRK. The main focus of the paper is on the results of a survey of 2,692 North Korean adult migrants in China. Recognizing certain biases and limitations, the study suggests that sample households have experienced an overall decline in food security, as evidenced by both the decline in government rations from an average of 120 grams per person per day to less than 60 grams per day, and by the increase in the percentage of households relying on foraging or bartering of assets as their principal source of food. It also is apparent that the period 1995-1998 has been marked by elevated household mortality, declining fertility, and steadily rising out-migration. Taken together, the signs point toward famine, whether that is defined as a discrete event--that is, as a regional failure in food production or distribution leading to elevated mortality from starvation and associated disease--or as a more complex social process whose sub-states include not only elevated mortality, but declining fertility

    Scattered waves generated near the source contains energy converted from the near-field waves to the far-field propagating waves, which can be used to achieve location accuracy beyond the diffraction limit. In this work, we apply a novel full-wave location method that combines a grid-search algorithm with the 3D Green's tensor database to locate the Non-Proliferation Experiment (NPE) at the Nevada test site and the North Korean nuclear tests. We use the first arrivals (Pn/Pg) and their immediate codas, which are likely dominated by waves scattered at the surface topography near the source, to determine the source location. We investigate seismograms in the frequency of [1.0 2.0] Hz to reduce noises in the data and highlight topography scattered waves. High resolution topographic models constructed from 10 and 90 m grids are used for Nevada and North Korea, respectively. The reference velocity model is based on CRUST 1.0. We use the collocated-grid finite difference method on curvilinear grids to calculate the strain Green's tensor and obtain synthetic waveforms using source-receiver reciprocity. The `best' solution is found based on the least-square misfit between the observed and synthetic waveforms. To suppress random noises, an optimal weighting method for three-component seismograms is applied in misfit calculation. Our results show that the scattered waves are crucial in improving resolution and allow us to obtain accurate solutions with a small number of stations. Since the scattered waves depends on topography, which is known at the wavelengths of regional seismic waves, our approach yields absolute, instead of relative, source locations. We compare our solutions with those of USGS and other studies. Moreover, we use differential waveforms to locate pairs of the North Korea tests from years 2006, 2009, 2013 and 2016 to further reduce the effects of unmodeled heterogeneities and errors in the reference velocity model.

    In an analysis of probabilistic risk, safety, and reliability of a nuclear power plant, the reliability data base (DB) must be established first. As the importance of the reliability data base increases, event reporting systems such as the US Nuclear Regulatory Commission's Licensee Event Report and the International Atomic Energy Agency's Incident Reporting System have been developed. In Korea, however, the systematic reliability data base is not yet available. Therefore, foreign data bases have been directly quoted in reliability analyses of Korean plants. In order to develop a reliability data base for Korean plants, the problem is which methodology is to be used, and the application limits of the selected method must be solved and clarified. After starting the commercial operation of Korea Nuclear Unit-1 (KNU-1) in 1978, six nuclear power plants have begun operation. Of these, only KNU-3 is a Canada Deuterium Uranium pressurized heavy-water reactor, and the others are all pressurized water reactors. This paper describes the proposed reliability data-base network (KNRDS) for Korean nuclear power plants in the context of two-stage Bayesian (TSB) procedure of Kaplan. It describes the concept of TSB to obtain the Korean-specific plant reliability data base, which is updated with the incorporation of both the reported generic reliability data and the operation experiences of similar plants

    The Kyoto Protocol on climate change has urged the world to explore ways of cutting down the greenhouse emissions, and it also boosted a number of nuclear power projects that is so-called the renaissance of nuclear power. Nuclear power has proven to be the cleanest energy source and one of the cheapest types of energies, compared with other energy sources. Korea began developing its nuclear power projects from the early 1970's. Since the first nuclear power plant Kori Unit 1, started commercial operation in 1978, Korea has continuously promoted the development of nuclear power projects, and today it operates 20 nuclear power units (17,716 MW), including 4 units of CANDU plants. Korea ranked No. 6 in the world in terms of installed capacity of nuclear power plants, and 40% of its domestic electricity generation comes from nuclear power plants. The average plant capacity factor was 95.5% in 2005, which is about 16% than the world average of around 79%. All the Korean nuclear power projects are led and implemented by Korea Hydro and Nuclear Power Co. (KHNP) which is the sole state-owned nuclear power project company spun off from Korea Electric Power Corporation (KEPCO) in 2001 as part of the government's program for electric industry restructuring. The cooperation between Romania and Korea in the nuclear power field began in March 2001. At industrial level a technical agreement between the Romanian Company Nuclearelectrica S.A. (SNN) and KHNP was signed in July 2003 for cooperation in Cernavoda NPP projects. The joint development of the Cernavoda NPP unit 3 was one of the major topics. Heavy water produced by Romanian Heavy Water plant at Drobeta Turnu Severin was supplied to KHNP (16 tones in 2001 and another 16 tones in 2004). The feasibility study for units 3 and 4 is being performed in two phases under leadership of SNN in cooperation with KHNP, AECL, ANSALDO and Deloitte and Touche as a financial advisor in Phase 2. It is expected that the appropriate securities

    This study examined the healthcare experiences of Korean immigrants aged 40-64 living in the North Carolina Triangle area of the Southeastern United States. Using a mixed methods design, we collected quantitative data via a questionnaire from 125 participants and conducted a focus group with 10 interviewees from December 2010 to February 2011. The quantitative data were analysed using t-tests and chi-square tests, and a thematic analysis was used for the focus group study. Questionnaire findings showed that only 27.2% had sufficient English skills to communicate adequately. Participants with insurance were significantly more likely to be employed (P tourism (22.6%) and lack of information or knowledge (6.5%). The following themes emerged from the data collected during the focus group: (i) barriers to utilisation of healthcare services; (ii) facilitators of utilisation of healthcare services; and (iii) social support seeking for health management. Our mixed methods study findings indicate that healthcare disparities exist among Korean immigrants and that a number of factors, including health literacy, may contribute to their poor health outcomes. Continued collaboration among community members, healthcare professionals and academicians is needed to discuss the community's health concerns and to develop sustainable programmes that will ensure meaningful access to care for those with limited English proficiency and medically underserved populations. © 2014 John Wiley & Sons Ltd.

    We examined factors affecting the depressive symptoms and the relationship between depression and quality of life among 131 North Korean adolescent refugees aged 12-24 years. We compared sociodemographic, social, and individual characteristics and perceived the quality of life between participants with and without depression. Thirty-seven refugees (28.2%) had clinically significant depressive symptoms. The refugees with depression were younger ( t = 2.67; p = 0.009), more likely to be male (χ² = 6.98; p = 0.009), and more likely to have a Chinese father (χ² = 9.05; p = 0.003) than those without depression. The refugees with depression had lower levels of psychological social support ( t = 2.96; p = 0.004) and resilience ( t = 4.24; p refugees at risk of depression.

    Current status of electric power in Korea is characterized by the end of August 2004 by a total installed capacity of about 62,000 MW while the total electricity generation is about 342,000 GWh. The installed capacity of nuclear power is 17,716 MW, sharing 29% of total installed capacity and presenting 38% of total electricity generation in Korea. In accordance with the provisions of the Long Term Energy Plan during the past 40 years, the installed capacity in Korea has been drastically increased. In the 1960's, major sources of electricity generation were locally-mined anthracite coal and hydro, but in the 1970's it was the imported oil. However, through diversification policy the dependence of the imported oil has been rapidly reduced and the share of coal , gas and nuclear generation has been steadily increased. According to the long-term power development plan updated last year, which is extended to 2017, the installed capacity in the year 2017 will be about 88,000 MW. At that time nuclear power will become the largest, sharing 30% and the shares of coal and gas fired power will be steadily decreased. Concerning the Nuclear Power Projects, there are four different nuclear power sites along the coast of Korean peninsula, Yonggwang, Kori, Wolsong and Ulchin. In addition to the currently operating 20 nuclear power plants, there are 6 more nuclear power plants under construction at Shin-Wolsong and Shin-Kori sites. Our efforts to enhance the technology, economy and safety of the nuclear power plants will be continuously pursued. Wolsong unclear power units 1, 2, 3 and 4 are CANDU type reactors which are same type as Romanian Cernavoda nuclear power plants. Operational performance, in terms of capacity factor of NPPs, has remained well above the world average and recorded 91.4% last year. Also, last year, the frequency of unplanned trip was 0.6 time per reactor. In 2004, ten NPPs achieved OCTF, which stands for One Cycle Trouble Free in 2004. Wolsong unit 1

    Accurate analysis of the operating characteristics of Nuclear Power Plants provides valuable information for both norman and abnormal operation. The information can be used for the enhancement of plant performance and safety. Usually, such analysis is performed using computer codes used for plant design or simulators. However, their usages are limited because special expertise is required to use the computer codes and simulators are not portable. Therefore, it deemed necessary to develop an NPA which minimizes those limitations and can be used for the analysis and simulation of Nuclear Power Plants. The purpose of this study is to develop a real-time best-estimate NPA for the Korean Nuclear Power Plants(KSNP). The NPA is an interactive, high fidelity engineering simulator. NPA combines the process model simulating the plant behavior with the latest computer technology such as Graphical User Interface(GUI) and simulation executive for enhanced user interface. The process model includes models for a three-dimensional reactor core, the NSSS, secondary system including turbine and feedtrain, safety auxiliary systems, and various control systems. Through the verification and validation of the NPA, it was demonstrated that the NPA can realistically simulate the plant behaviors during transient and accident conditions

    Site-specific atmospheric dispersion characteristics have been analyzed. The northwest and the southwest wind prevail on nuclear sites of Korea. The annual isobaric surface averaged for twenty years around Korean peninsula shows that west wind prevails. The prevailing west wind is profitable in the viewpoint of radiation protection because three of four nuclear sites are located in the east side. Large scale field tracer experiments over nuclear sites have been conducted for the purpose of analyzing the atmospheric dispersion characteristics and validating a real-time atmospheric dispersion and dose assessment system FADAS. To analyze the site-specific atmospheric dispersion characteristics is essential for making effective countermeasures against a nuclear emergency

  16. War Remembered, Revolution Forgotten: Recasting the Sino-North Korean Alliance in China’s Post-Socialist Media State

    2017-03-01

    Full Text Available From October 1950 to July 1953, the nascent Chinese state entered into a strategic alliance with North Korea; hundreds of thousands of Chinese soldiers shed blood on the Korean peninsula in defense of the socialist homeland and advancing Communist internationalism. But since the end of the Korean War, China has moved from revolutionary idealism and political radicalism in Mao’s era to the current post-socialist pragmatism and materialism. As the ideological winds shift, China’s contemporary propaganda apparatus must redefine the Korean War in order to reconcile the complexity of the war and wartime alliance with contemporary political concerns and popular views. By focusing on a documentary film, The Unforgettable Victory, produced by China’s leading state-run film studio in 2013, this article explores the ways in which the official media of the post-socialist era presents the past revolutionary war. The new film celebrates the splendid valor of Chinese soldiers, civilians’ heroic sacrifices, and the war’s nationalist legacy; however, it purposefully forgets the revolutionary fervor and internationalist sentiments that once forged the Sino–North Korean alliance and empowered wartime mobilization. This article examines the process of remembering and forgetting, and reveals government propaganda’s latest efforts to demobilize contemporary viewers while infusing the past revolutionary war with ideological clarity and political certainty in post-socialist China.

    Full Text Available The purpose of this paper is to challenge the dominant narrative of Christian service providers working for North Korean refugees’ welfare, and to articulate the perspectives of non-Christian aid recipients, especially North Korean refugees in China and South Korea. Drawing upon postcolonialism, I will unpack dysfunctions of Christian missions and ministries while relating them to anthropological insights and ethnographic research data. As a Christian scholar, I attempt to invite Christian leaders and field workers to engage in critical reflections on their goals, dispositions, and strategies in relating to the culturally, politically, and economically marginalized. This paper is aimed to offer opportunities for Christian missionaries to critique their colonial models and to reclaim their missions that decolonize both missionaries and the missionized.

    The Korean government plans to increase strategically focused R and D investment in some promising nuclear technology areas to create export opportunities of technology in a global nuclear market. The purpose of this paper is to present a decision support process for selecting promising nuclear technology with the perspective of exportability by using the AHP based on extensive data gathered from nuclear experts in Korea. In this study, the decision criteria for evaluating the export competitiveness of nuclear technologies were determined, and a hierarchical structure for the decision-making process was systematically developed. Subsequently relative weights of decision criteria were derived using AHP methodology and the export competitiveness of nuclear technology alternatives was quantified to prioritize them. We discuss the implications of our results with a viewpoint toward national nuclear technology policy.

    In December 2009, the Republic of Korea won the contract to build 4 1,400 MW nuclear power reactors worth USD 20 billion in the UAE. The states-owned KEPCO will complete the turnkey project to the UAE including design, engineering, construction, nuclear fuel, operations, maintenance and technical support. Since sensitive nuclear technologies convertible to military purpose can be spread by the transfer of commercial nuclear power plant, it is essential prerequisite to implement nuclear export control tenaciously and effectively. About twenty years have passed since the Republic of Korea introduced export control system in domestic laws and regulations. Marking a major historical milestone in 2009 by ranking among global nuclear suppliers, the Korean government made a major step forward in export control framework to support its next nuclear export goal.

    Full Text Available Objectives: The present study aimed to analyze the factors that could affect the health-promoting behaviors of North Korean adolescent refugees residing in South Korea. Methods: Questions about their sociodemographic variables, subjective health status, healthy living habits, and health-promoting behaviors were asked. Results: Statistically significant differences were found in religion (t=2.30, p<0.05, having family members in South Korea (t=2.02, p<0.05, and subjective health status (t=4.96, p<0.01. Scores on health-responsible behaviors were higher with higher age (t=2.90, p<0.01 and for subjects without family or friends (t=2.43, p<0.05. Higher physical-activity behaviors were observed in males (t=3.32, p<0.01, in those with better subjective health status (t=3.46, p<0.05 and lower body mas index (t=3.48, p<0.05, and in smokers (t=3.17, p<0.01. Nutritional behaviors were higher in those who followed a religion (t=2.17, p<0.05. Spiritual growth behaviors were higher in those who followed a religion (t=4.21, p<0.001, had no family in South Korea (t=2.04, p<0.05, and had higher subjective health status (t=5.74, p<0.01. Scores on interpersonal relationships and stress-management behaviors were higher for those with higher subjective health status. A multiple regression analysis showed greater effects on health-promoting behaviors when subjective health status was better. Older people and non-smokers exhibited more health-responsible behaviors, while more physical-activity behaviors and spiritual growth activities were observed when subjective health status was better. Interpersonal relationship behaviors had positive effects on those with good subjective heath status and on non-smokers. Conclusions: Based on the results of the current study, an alternative was suggested for promoting health in North Korean adolescent refugees.

    The objective of this paper is to establish Containment spray operational technical bases for the typical Korean Standard Nuclear Power plants (Ulchin units 3 and 4) by modeling the plant, and analyzing a loss of coolant accident (LOCA) using the MAAP code. The severe accident phenomena at nuclear power plants have large uncertainties. For the integrity of the reactor vessel and containment safety against severe accidents, it is essential to understand severe accident sequences and to assess the accident progression accurately by computer codes. Furthermore, it is important to attain the capability to analyze a advanced nuclear reactor design for a severe accident prevention and mitigation.

    Increasing awareness on environmental damage and climate change has induced many nations to engage in green growth. South Korea, as one of the largest consumers of energy, is no exception and has shown its determination to pursue green growth in the future. In order to do so, South Korea plans to substitute fossil fuel with alternative sources in electricity generation. However, the key constraint to green growth is the high cost faced by renewable electricity generation. Fortunately, nuclear energy can serve as an economic alternative to fossil fuel. To achieve CO 2 emission reduction and faster economic growth, it is wise to analyze prospects of alternatives using experience curve framework. The results and industry background are consistent for nuclear technology, and the results suggest that nuclear should serve as the main substitute. Consideration of policy risk inherent in renewable also strengthens the argument. Renewable technologies, on the other hand, showed overstated learning capacity that is partially inconsistent with technological background. Nevertheless, the renewable (photovoltaic and fuel cell) should help nuclear marginally in substituting fossil fuel in South Korea's Electricity Generation. - Highlights: ► Progress ratios of renewable energy show great prospect. ► The policy risk is inherent in renewable and may overestimate its prospect. ► Nuclear sources are economic and less affected by policy risk. ► Fuel cell and photovoltaic should help nuclear marginally in green growth.

    North Korea has chosen nuclear weapons as the means to protect its sovereignty. Despite international society's endeavors and sanctions to encourage North Korea to abandon its nuclear ambition, North Korea has repeatedly conducted nuclear testing. In this paper, the reason for North Korea's addiction to a nuclear arsenal is addressed within the framework of cognitive psychology. The prospect theory addresses an epistemological approach usually overlooked in rational choice theories. It provides useful implications why North Korea, being under a crisis situation has thrown out a stable choice but taken on a risky one such as nuclear testing. Under the viewpoint of prospect theory, nuclear tests by North Korea can be understood as follows: The first nuclear test in 2006 is seen as a trial to escape from loss areas such as financial sanctions and regime threats; the second test in 2009 was interpreted as a consequence of the strategy to recover losses by making a direct confrontation against the United States; and the third test in 2013 was understood as an attempt to strengthen internal solidarity after Kim Jong-eun inherited the dynasty, as well as to enhance bargaining power against the United States. Thus, it can be summarized that Pyongyang repeated its nuclear tests to escape from a negative domain and to settle into a positive one. In addition, in the future, North Korea may not be willing to readily give up its nuclear capabilities to ensure the survival of its own regime

  5. The improvement of nuclear safety regulation : American, European, Japanese, and South Korean experiences

    International Nuclear Information System (INIS)

    Cho, Byung Sun

    2005-01-01

    Key concepts in South Korean nuclear safety regulation are safety and risk. Nuclear regulation in South Korea has required reactor designs and safeguards that reduce the risk of a major accident to less than one in a million reactor-years-a risk supposedly low enough to be acceptable. To data, in South Korean nuclear safety regulation has involved the establishment of many technical standards to enable administration enforcement. In scientific lawsuits in which the legal issue is the validity of specialized technical standards that are used for judge whether a particular nuclear power plant is to be licensed, the concept of uncertainty law is often raised with regard to what extent the examination and judgement by the judicial power affects a discretion made by the administrative office. In other words, the safety standards for nuclear power plants has been adapted as a form of the scientific technical standards widely under the idea of uncertainty law. Thus, the improvement of nuclear safety regulation in South Korea seems to depend on the rational lawmaking and a reasonable, judicial examination of the scientific standards on nuclear safety

    The meltdowns of the Chernobyl and Fukushima I nuclear reactors are fundamentally linked to their organizational characteristics, as they caused severe social and economic disruptions with equally significant environmental and health related impacts. This shows that we have to find practical solutions to reactor safety from various organizational standpoints by introducing a systematic approach to the issue of organizational deficiencies and human errors. We posit that one of the fundamental causes of organizational deficiencies can be derived from an organizational culture. An organizational culture has both formal and informal types. Generally, organizational culture refers to the common beliefs, values, norms, symbols, and language systems that organizational members use when they add meaning to their organizational behavior within their specific organizations. The purpose of this study is threefold. First, we are interested in finding internal contradictions between Korean organizational culture and U.S.-derived organizational safety mechanisms applied to the operation of Korean NPPs (Nuclear Power Plants). We want to discern safety related problems that are thought to have occurred routinely within the parameters of Korean NPPs owing to the use of U.S. safety mechanisms. Second, we compare the Korean and Japanese organizational culture in NPP mainly on safety and comfort cultures in order to cope with the cultural problems. Third, we want to propose an alternative model of safety mechanisms that are more appropriate for Korean organizational culture, using a system dynamic model that we devised based on empirical observations from the NPPs and factors drawn from the extant literature as compared with Japanese organizational culture.

    We have developed a four-dimensional variation data assimilation technique (4D-var) and utilized it to reconstruct three-dimensional images of the ionospheric hole created during Kwangmyongsong-4 rocket launch. Kwangmyongsong-4 was launched southward from North Korea Sohae space center (124.7°E, 39.6°N) at 00:30 UT on 7 February 2016. The data assimilated were Global Positioning System total electron content from the South Korean Global Positioning System-receiver network. Due to lack of publicized information about Kwangmyongsong-4, the rocket was assumed to inherit its technology from previous launches (Taepodong-2). The created ionospheric hole was assumed to be made by neutral molecules, water (H2O) and hydrogen (H2), deposited in exhaust plumes. The dispersion model was developed based on advection and diffusion equation, and a simple asymmetric diffusion model assumed. From the analysis, using the adjoint technique, we estimated an ionospheric hole with the largest depletion existing around 6-7 min after launch and gradually recovering within 30 min. These results are in agreement with temporal total electron content analyses of the same event from previous studies. Furthermore, Kwangmyongsong-4 second stage exhaust emissions were estimated as 1.9 × 1026 s-1 of which 40% was H2 and the rest H2O.

    Although many North Korean (NK) refugee women are victims of domestic violence (DV) in North Korea, face sexual exploitation during migration, and remain at risk of DV while adapting to life in South Korea, there is no empirical evidence about risk factors for DV in this population. To fill this gap, this study examined whether gender role beliefs, child abuse history, and sociocultural adaptation were associated with past-year physical, emotional, sexual, and economic abuse, and whether they were associated with multiple forms of abuse. We also explored whether these associations were similar or different across different types of DV among NK refugee women. A sample of 180 ever-married NK refugee women in South Korea from the 2010 National Survey on Family Violence was used for analysis. Physical abuse was associated with more traditional gender role beliefs; emotional abuse and multiple forms of abuse were associated with lower levels of sociocultural adaptation; and sexual and economic abuse were associated with an increased likelihood of childhood abuse and poor sociocultural adaptation. Our study findings underscore the importance of assisting NK refugee women to be better adapted to the new culture in a practical way, because better sociocultural adaptation might protect them from experiencing various types of abuse. At the same time, findings of this study highlight the need for empowering NK refugee women who report physical abuse by educating their rights and altering their traditional beliefs of gender roles, and screening of childhood abuse and providing culturally sensitive psychotherapy to those who report sexual or economic abuse. Moreover, we suggest future studies to examine correlates of different forms of abuse separately because they can inform culturally tailored interventions for abused NK refugee women. To prevent further victimization, educational programs should be provided to NK refugee women at an early stage of resettlement in South Korea.

    Full Text Available After confronting each other as enemies during the Korean War, South Korea and China established diplomatic relations in 1992, forty years after fighting had ended. Around this time, the Chinese city of Dandong near the northern border of the Korean peninsula erected a memorial to observe the fortieth anniversary of the Korean War. In the twenty years since, China has become South Korea’s primary economic partner and its largest market for exports. In effect, the memory of wartime hostility has coexisted with the reality of economic cooperation. This article examines how the Korean War, known in China as the “War to Resist U.S. Aggression and Aid Korea,” is commemorated by the war memorials in China, with a specific focus on the memorial in Dandong. It also discusses how North and South Korea have responded to the contrasting perspectives on the war embodied by these memorials, and it concludes with some reflections about how the memory of war can be restructured to convey a message of peace for the future.

    For a certain period following the establishment of diplomatic relations between China and South Korea after the end of the Cold War, relations between China and North Korea deteriorated enormously. Amid escalating tensions due to North Korea's development of nuclear weapons, President Kim Il-Sung died suddenly. Sensing an impeding crisis due to North Korea's destabilized regime, China began providing North Korea with aid, and this marked a move aimed at restoring the China-North Korean relat...

    The disposal facility of the spent nuclear fuel will be operated from 2051. This paper presents the ENVI code developed by GoldSim Software to simulate options for managing spent nuclear fuel (SNF) in South Korea. The ENVI is a simulator to allow decision-makers to assist to evaluate the performance for spent nuclear fuel management. The multiple options for managing the spent nuclear fuel including the storage and transportation are investigated into interim storage, permanent disposal in geological repositories and overseas and domestic reprocessing. The ENVI code uses the GoldSim software to simulate the logistics of the associated activities. The result by the ENVI model not only produces the total cost to compare among the multiple options but also predict the sizes and timings of different facilities required. In order to decide the policy for spent nuclear management this purpose of this paper is to draw the optimum management plan to solve the nuclear spent fuel issue in the economical aspects. This paper is focused on the development of the ENVI's logic and calculations to simulate four options(No Reprocessing, Overseas Reprocessing, Domestic Reprocessing, and Overseas and Domestic Reprocessing) for managing the spent nuclear fuel in South Korea. The time history of the spent nuclear fuel produced from both the existing and future NPP's can be predicted, based on the Goldsim software made available very user friendly model. The simulation result will be used to suggest the strategic plans for the spent nuclear fuel management.

    The view is given that the US government financed South Korea's nuclear program at taxpayer expense. Westinghouse Electric Co., which supplied the equipment for Korea's reactors, was said to be the taxpayers' beneficiary. US participation was justified on grounds of commercial benefits to US companies, fuel suppliers, and world prestige as a promoter of peaceful nuclear applications and assistance to developing countries. The Export-Import Bank provided funding after strong urging by the US Embassy in Korea and Westinghouse. The author states that pressure was also put on the Korean government to award contracts to US suppliers. The negotiations have spanned periods of unrest in Korea

    For the Korean Standard Nuclear Power Plant (KSNPP) designed based on Combustion Engineering (CE) System 80, the Westinghouse nuclear design code system ALPHA/PHOENIX/ANC was applied to the follow-up design of initial and reload core of KSNPP. The follow-up design results of Yonggwang Unit 3 Cycle 1, 2 and Yonggwang Unit 4 Cycle 1 have shown good agreements with the measured data. The assemblywise power distributions have shown less than 2% average differences and critical boron concentrations have shown less than 20 ppm differences. All the low power physics test parameters are in good agreement. Consequently, APA design code system can be applied to KNSPP cores. (author)

  18. Imaginary Savior: the image of the nuclear bomb in Korea, 1945-1960.

    2009-01-01

    Two atomic bombs dropped on Hiroshima and Nagasaki in August 1945 brought the unexpected liberation of Korea from the 35-year Japanese occupation. Koreans therefore had a very favorable and positive image of the nuclear bomb and nuclear energy from the beginning. The image of the nuclear bomb as "savior" was strengthened during the Korean War when the United States openly mentioned the possible use of the nuclear bomb against North Korean and Chinese military. After the end of the Korean War in July 1953 South Koreans strongly supported the development of the nuclear bomb in order to deter another North Korean invasion. When the US government provided South Korea with a research nuclear reactor in the late 1950s, most South Koreans hailed it as the first step to developing their own nuclear bomb. This paper will analyze how and why the savior image of the nuclear bomb originated and spread in Korea during the 1950s.

    As a result of conducting a 45 minute-long seminar on the principles, state of use, advantages, and disadvantages of nuclear power generation for Korean elementary, middle, and high school students, the levels of perception including the necessity (p<0.017), safety (p<0.000), information acquisition (p<0.000), and subjective knowledge (p<0.000), objective knowledge (p<0.000), attitude (p<0.000), and behavior (p<0.000) were all significantly higher. This indicates that education can be effective in promoting widespread social acceptance of nuclear power and its continued use. In order to induce behavior change toward positive judgments on nuclear power generation, it is necessary to focus on attitude improvement while providing the information in all areas related to the perception, knowledge, attitude, and behavior. Here, the positive message on the convenience and the safety of nuclear power generation should be highlighted.

    2005-01-01

    Korea Electric Power Industry Code (KEPIC), a set of integrated standards applicable to the design, construction and operation of electric power facilities including nuclear power plants, has been developed on the basis of referring to the prevailing U.S. codes and standards which had been applied to the electric power facilities in Korea. Being the developing and managing organization of KEPIC, Korea Electric Association (KEA) published its first edition in 1995, the second in 200,0 and is expected to publish the 2005 edition. KEPIC was applied to the construction of Ulchin Nuclear Units 5 and 6 in 1997, and will be applicable to the construction of forthcoming nuclear power plants in Korea. Along with the effectuation of the Agreement on Technical Barriers to Trade (TBT) in 1995, the international trend related to codes and standards is changing rapidly. The KEA is, therefore, making its utmost efforts so as for KEPIC to keep abreast with the changing environment in international arena. KEA notified ISO/IEC Information Centre of its acceptance of the Code of Good Practice in the Agreement on TBT. The 2005 KEPIC edition will be retrofitted according to the ISO/IEC Guide 21- Adoption of International Standards as regional or national standards. KEA's efforts will help KEPIC correspond with international standards such as ISO/IEC standards, and internationally recognized standards such as ASME codes and standards. (authors)

  2. Seismological investigation of September 09 2016, North Korea underground nuclear test

    Full Text Available On Sep. 9, 2016, a seismic event of mb 5.3 took place in North Korea. This event was reported as a nuclear test. In this study, we applied a number of discriminant techniques that facilitate the ability to distinguish between explosions and earthquakes on the Korean Peninsula. The differences between explosions and earthquakes are due to variation in source dimension, epicenter depth and source mechanism, or a collection of them. There are many seismological differences between nuclear explosions and earthquakes, but not all of them are detectable at large distances or are appropriate to each earthquake and explosion. The discrimination methods used in the current study include the seismic source location, source depth, the differences in the frequency contents, complexity versus spectral ratio and Ms-mb differences for both earthquakes and explosions. Sep. 9, 2016, event is located in the region of North Korea nuclear test site at a zero depth, which is likely to be a nuclear explosion. Comparison between the P wave spectra of the nuclear test and the Sep. 8, 2000, North Korea earthquake, mb 4.9 shows that the spectrum of both events is nearly the same. The results of applying the theoretical model of Brune to P wave spectra of both explosion and earthquake show that the explosion manifests larger corner frequency than the earthquake, reflecting the nature of the different sources. The complexity and spectral ratio were also calculated from the waveform data recorded at a number of stations in order to investigate the relation between them. The observed classification percentage of this method is about 81%. Finally, the mb:Ms method is also investigated. We calculate mb and Ms for the Sep. 9, 2016, explosion and compare the result with the mb: Ms chart obtained from the previous studies. This method is working well with the explosion. Keywords: Discrimination, Seismic source location, Brune model, Spectral parameters, Complexity method, Mb: Ms

    Korean fast reactor scenarios have been analyzed for various kinds of conversion ratio (CR) by the DANESS system dynamic analysis code. The once-through fuel cycle analysis was modeled based on the Korean 'National Energy Basic Plan' up to 2030 and a postulated nuclear demand growth rate until 2150. The fast reactor scenario analysis has been performed for three kinds of conversion ratios such as 0.3, 0.61 and 1.0. Through the calculations, the nuclear reactor deployment scenario, front-end cycle, back-end cycle, and long-term heat load have been investigated. From the once-through results, it is shown that the nuclear power demand would be ∼70 GWe and the total amount of the spent fuel accumulated by 2150 would be ∼168000 t. The fast reactor (FR) scenario analysis results show that the spent fuel inventory and out-pile transuranic element (TRU) can be reduced by increasing the fast reactor conversion ratio. Furthermore, the long-term heat load of spent fuel decreases with increasing the conversion ratio. However, it is known that the deployment of a fast reactor of low conversion ratio does not much reduce the spent fuel and out-pile TRU inventory due to the fast reactor deployment limitation which is related to the availability of TRU

    The post-LOCA long term cooling (LTC) performance of the Korean Standard Nuclear Power Plant (KSNPP) is analyzed for both small break loss-of-coolant accidents (LOCA) and large break LOCA at cold leg. The RELAP5/MOD3.2.2 beta code is used to calculate the LTC sequences based on the LTC plan of the Korean Standard Nuclear Power Plants (KSNPP). A standard input model is developed such that LOCA and the followed LTC sequence can be calculated in a single run for both small break LOCA and large break LOCA. A spectrum of small break LOCA ranging from 0.02 to 0.5 ft 2 of break area and a double-ended guillotine break are analyzed. Through the code calculations, the thermal-hydraulic behavior and the boron behavior are evaluated and the effect of the important action including the safety injection tank (SIT) isolation and the simultaneous injection in LTC procedure is investigated. As a result, it is found that the sufficient margin is available in avoiding the boron precipitation in the core. It is also found that a further specific condition for the SIT isolation action need to be setup and it is recommended that the early initiation of the simultaneous injection be taken for larger break LTC sequences.

    In Korea, 17 nuclear power plants composed of 13 pressurized water reactors and 4 CANDU reactors are currently in operation. The cumulative amounts of low and intermediate level radioactive waste in nuclear power plant reached 58,718 drums (unit: 200 liter) in 2001. Efforts to construct LILW disposal facility are continued and its first operation is planned in the year 2008. Its first stage capacity is assumed to be 100,000 drums and total capacity will reach to 800,000 drums. Radwaste disposal site selection is an urgent national project at present time. Regulations and guidelines require detailed information about the radioactive waste package and its contents prior to the transport to the disposal sites. The Enforcement Decree of the Korean Atomic Energy Act (articles 234-17) requires the Minister of Science and Technology (MOST) of Korea to establish regulation for the waste acceptance (MOST notice. 1196-10). It requires detailed information about the radioactive waste package and its contents such as activity of radionuclides, total activities, types and characteristics of waste. For the measurement of the concentrations and activities of radionuclides in radwaste drum, a radionuclides assay system is installed at Korean nuclear power plant (KORI site) in 1996. The waste drum can be measured in the vertical direction with eight vertical segments while in the radial direction also with eight segments. Using this measurement method, homogeneous and non-homogeneous waste drum can be measured. Scaling factor methods have been played a dominant role in the determination of the radionuclides concentration in this system. For corrosion product, generic scaling factors were used due to the similarity and better-characterized properties of Korean analyzed data as compared with the worldwide data base of PWR industry. For fission product and TRU nuclides, it is not easy to determine the generic scaling factors. Thus simple model reflecting the operation history of power

    Hyper duplex stainless steels have been developed in Korea for the purpose of application to the seawater system of Korean nuclear power plants. This system supplies seawater to cooling water heat exchanger tubes, related pipes and chlorine injection system. In normal operation, seawater is supplied to heat exchanger through the exit of circulating water pump headers, and the heat exchanged sea water is extracted to the discharge pipes in circulating water system connected to the circulating water discharge lines. The high flow velocity of some part of seawater system in nuclear power plants accelerates damages of components. Therefore, high strength and high corrosion resistant steels need to be applied for this environment. Hyper duplex stainless steel (27Cr-7.0Ni-2.5Mo-3.2W-0.35N) has been newly developed in Korea and is being improved for applying to nuclear power plants. In this study, the physical and mechanical properties and corrosion resistance of newly developed materials are quantitatively evaluated in comparative to commercial stainless steels in other countries. The properties of weld and HAZ (heat affected zone) are analyzed and the best compositions are suggested. The optimum conditions in welding process are derived for ensuring the volume fraction of ferrite(α) and austenite(γ) in HAZ and controlling weld cracks. For applying these materials to the seawater heat exchanger, CCT and CPT in weldments are measured. As a result of all experiments, it was found that the newly developed hyper duplex stainless steel WREMBA has higher corrosion resistance and mechanical properties than those of super austenitic stainless steels including welded area. It is expected to be a promising material for seawater systems of Korean nuclear power plants

    Despite the pressure from Scandinavian and other European countries it is not realistic to expect Russia to abandon its nuclear energy projects, which are badly required for the power starved Northwest region of the country. Russia will probably continue to use and develop nuclear technology because of its huge infrastructure and enormous manpower. In this regard Russia needs help from Western countries to fund a solution to the problem. One of the most important concerns of Norway is related to the naval shipyards in the Kola peninsula and Archangelsk region which include nuclear-powered submarines and about 5000 tons of solid waste generated annually by the Northern Fleet nuclear reactors and at the two shipyards. Norway has taken the lead in co-operating with Russia in working out solutions, but there is no help from the Russian authorities

    Jeong, Chang Joon

    2004-12-01

    The Korean nuclear fuel cycle scenario was analyzed by the dynamic analysis method, including Pressurized Water Reactor (PWR), Canadian Deuterium Uranium (CANDU) and fast reactor systems. For the once-through fuel cycle model, the existing nuclear power plant construction plan was considered up to 2016, while the nuclear demand growth rate from the year 2016 was assumed to be 1%. After setting up the once-through fuel cycle model, the Korea Advanced Liquid Metal Reactor (KALIMER) scenario was modeled to investigate the fuel cycle parameters. For the analysis of the fast reactor fuel cycle, both KAILMER-150 and KALIMER-600 reactors were considered. In this analysis, the spent fuel inventory as well as the amount of plutonium, Minor Actinides (MA) and Fission Products (FP) of the recycling fuel cycle was estimated and compared to that of the once-through fuel cycle. Results of the once-through fuel cycle calculation showed that the demand grows up to 64 GWe and total amount of spent fuel would be ∼102 kt in 2100. If the KALIMER scenario is implemented, the total spent fuel inventory can be reduced by ∼80%. However it was found that the KALIMER scenario does not contribute to reduce the amount of MA and FP, which is important when designing a repository. For the further destruction of MA, an actinide burner can be considered in the future nuclear fuel cycle

    This report describes various factors on the IASCC of reactor internals in terms of fluence, stress, water chemistries and materials. Materials of each components of Korean nuclear power plants have been surveyed. A technical report for a management of reactor internals issued by EPRI was reviewed for a selection of most susceptible area among many components. Baffle former bolts are considered to be the most susceptible parts due to high irradiation level(fluence) and high tensile stress. Neutron fluence of Kori-1 and Kori-2 was calculated based on fuel exchange history, fuel performance and plant operation history. This report will be used for more advanced inspection and maintenance guidelines development by supplying inspection intervals and components (most susceptible regions) for the long term operation plants

    The post-LOCA long term cooling (LTC) performance of the Korean Standard Nuclear Power Plant (KSNPP) is analyzed for both small break LOCA and large break LOCA. The RELAP5/MOD3.2.2 code is used to calculate the LTC sequences based on the LTC plan of the KSNPP. A standard input model is developed such that LOCA and the followed LTC sequence can be calculated in a single run for both small break LOCA and large break LOCA. A spectrum of small break LOCA ranging from 0.02 to 0.5 ft 2 of break area and a double-ended guillotine break are analyzed. Through the code calculations, the thermal-hydraulic behavior and the boron behavior are evaluated and the effect of the important manual action including the safety injection tank isolation in LTC procedure is investigated

    This study aims to introduce the current role of nuclear power of Korea as the economic and low carbon emitter in the long term expansion planning and to improve the public acceptance of nuclear as the environmentally friendliness energy source. Nuclear and coal have been selected as the major electricity sources due to the insufficient domestic energy resources, and will provide more than 60% of total electricity generation in Korea for quite some time. National energy policy addressing environmental friendliness, stable supply and least cost has made it difficult to decide which energy resource is the best for the long term energy planning. Climate change regime will diminish the coal power plants in generation amount, the public still keeps nuclear at a distance and insists to replace nuclear by renewable and renewable doesn't any guarantee of stable supply although its economics is fast being improved. Therefore, it is necessary to analyze the long-term power expansion planning in various points of view such as environmental friendliness, benefit of carbon reduction and system reliability as well as least cost operation. The objective and approach of this study are to analyze the proper role of nuclear power by comparing the different types of scenarios in terms of the system cost changes, CO 2 emission reduction and system reliability. The results from this analysis are useful for the Korean government in charge of long-term energy policy to go over what kinds of role can each electric resources play and what are the best way to solve the triangular dilemma as economics, environmental friendliness, stable supply of the electricity

    Full text: Synopsis. The prospects for growth for the nuclear power industry in the Republic of Korea, have improved notably in last few years, as the need for generating capacity grows to meet burgeoning energy demand and developmental needs, and as environment, climate change and energy supply security continue become matters of rising concern. Nuclear technology itself has also changed, with evolutionary and innovative changes in reactor design and safety measures. Nuclear technology development both requires and fosters human resource development (HRD). A continuous, consistent and well-managed programme of HRD is crucial to assure continuity over time in the needed capacities, skills and knowledge, and to establish and maintain a cadre of manpower variously trained in different nuclear-related skills and educated in nuclear relevant fields. It also fosters the development of spin-off industries and synergies. Productive and goal-oriented HRD and M is a dynamic long-term process that balances the dynamics of supply and demand of human resources with respect to the education, recruitment, maintenance and proper training of the human resources needed for industry operations as well as innovation. Such a programme in fact was the foundation for the birth of the Korean nuclear industry, with the government sponsoring nuclear-related- training and education for hundreds of persons under the tutelage of companies and countries overseas having experience with nuclear and related sciences and technology. This cadre, once repatriated, formed the nucleus for domestic training and education programmes as an integral part of nuclear energy development and consistent with national policies. HRD and M in Korea today comprises an educational network among academic and research institutes, government and industry. Forming such a cadre is not the result of a one-off training process, but must be planned and sustained consistently over time and its talents regularly applied

    Recently, countries all over the world are becoming aware of the values and importance of nuclear energy which can help respond to energy crises caused by a sharp rise in oil prices and protect the earth from global warming. Since 1978, when Kori Unit 1(587MW), opened the nuclear generation era as a semi-domestic energy resource in Korea which is absolutely in short supply of energy, nuclear power generation in Korea has developed continuously for the past 28 years. Four new units including the Yonggwang 5 and 6 and Ulchin 5 and 6 have been successfully completed, raising the total nuclear installed capacity to 17,716MW from 20 units. At present, the nuclear generation in Korea is stably supplying about 40% of total electric generation, which is the fundamental energy of the nation, supporting the dynamic economic growth of Korea. In particular, Korean nuclear industry has been achieving excellent performance in nuclear power plant operation. The average capacity factor in 2005 hit the record of 95.5%, surpassing the previous record of 94.2% in 2003 in two years. Kori Unit 4 and another four units were listed at the top five in the capacity factor rating list of 2005 released by Nucleonics Week. In 2005, the site for radioactive waste disposal, which had been a long-cherished hope and the largest pending issue of the nuclear industry, was successfully selected in Korea through resident ballot as the first case of a national policy project, and as such, a national agenda was solved after 19 long years. Such a method in site selection has a significant meaning and establishes an excellent precedence; a large national policy project was decided upon by the residents themselves. As one of the model countries of building and operating nuclear power plants and technological independence, Korea is willing to contribute to the common goals of the world nuclear circle which can be summarized into energy security and environment preservation, by sharing accumulated

    Full text of publication follows: POSCO has developed duplex stainless steel (S32750) and hyper super duplex stainless steels for the purpose of using them in the secondary circulation cooling water system in Korean nuclear power plants. This system supplies seawater to cooling water heat exchanger tubes, related pipes and chlorine injection system. In normal operation, seawater is supplied to heat exchanger through the exit of circulation pump headers and the heat exchanged sea water is extracted to the discharge pipes in circulation cooling water system connected to the circulation water discharge lines. The flow velocity of circulation cooling water system in nuclear power plants is high and damages of components from corrosion are severe. Therefore, this environment makes requiring of using high strength and high corrosion resistant steels. Hyper duplex stainless steel (27Cr-7.0Ni-2.5Mo-3.2W-0.35N) has been newly developed in Korea and is being improved for applying to nuclear power plants. In this study, the physical and mechanical properties and corrosion resistance of currently producing stainless steels and newly developed materials are qualitatively evaluated in comparative to commercial stainless steels in other countries. The properties of weld are analyzed and the best compositions of welding rod are suggested. The optimum weld condition is derived for ensuring HAZ phase ratios and controlling weld cracks. For applying these materials to the seawater heat exchanger, CCT and CPT in weldments are measured using mock-up tube testers that are newly designed for this study. Coupons of candidate materials are introduced in the real system and corrosion resistance of them are analyzed. As results of all experiments, the current CCT and CPT criteria in Korean nuclear power plants are reviewed, and the more actual and strengthened criteria will be suggested. The real scale components made of newly developed hyper super duplex stainless steel will be applied to

    Full Text Available This study aimed at analyzing the bibliometric characteristics and content of medical articles from North Korea in PubMed and characterizing the patterns of international cooperation of medical researchers in North Korea. We hypothesized that the number of publications from North Korea in PubMed has increased recently as a result of active cooperation with foreign researchers. PubMed was searched on July 19, 2017 using the search term “(North Korea [Affiliation] OR Democratic People’s Republic of Korea [Affiliation] OR DPRK [Affiliation].” The content of medical articles was analyzed and cooperative work with foreign researchers was noted. The number of medical articles in PubMed through July 2017 was 16, of which 2 were by North Korean authors only. From the content of these articles, it was found that researchers in top-notch institutions, including Kim Il Sung University, can access the internet, and that a dental caries prevention program supported by Finland has been in place for more than 10 years. The number of publications from North Korea in PubMed has increased recently, although the amount is still very small. Providing internet access to North Korean researchers will accelerate their submissions to international journals.

    Nuclear power facilities and policies are based upon their acceptability to local residents and citizens. In Korea, where nuclear power should be consistently used for national energy security and economic growth, it is important to enhance the social acceptability of nuclear power. To do so, it is necessary to relieve the minds of the Korean people and global nuclear power communities regarding safety. However, there is sharp division on the perception of nuclear power safety between the expert group of operators, philosophers, and regulators, and ordinary citizens, local residents, media, and anti-nuclear groups. This study designed an experiment on knowledge change as part of an educational strategy to enhance public understanding and develop extensive bonds of sympathy for nuclear power generation adequate for Korean society. In order to provide fundamental evidence for planning an educational intervention strategy, this study analyzed the knowledge change of elementary, middle, and high school students, who are then expected to impact education of the general population. As a result of conducting a 45 minute-long education on the principles, state of use, advantages, and disadvantages of nuclear power generation for Korean elementary, middle, and high school students, the levels of objective knowledge (p<0.000) was significantly higher. This indicates that if education for enhancing social acceptance in Korea argued nuclear power should be constantly used, an education effect could be anticipated. Although objective knowledge does not have any direct influence on behavior change, it is an important variable for attitude change, and thus information on objective knowledge should be offered as well. Here, the contents preferred by the education subjects should also be considered.

    Job stress is a harmful physical and emotional response that occurs when there is a poor match between job demands and the capabilities, resources, or needs of the worker. Stress-related disorders encompass a broad array of conditions, including psychological disorders (e.g., depression, anxiety, posttraumatic stress disorder) and other types of emotional strain (e.g., dissatisfaction, fatigue, tension, etc.), maladaptive behaviors (e.g., aggression, substance abuse), and cognitive impairment (e.g., concentration and memory problems). In turn, these conditions may lead to poor work performance or even injury. Job stress is also associated with various biological reactions that may lead ultimately to compromised health, such as cardiovascular disease or in extreme cases, death. In Korea, organizational job stress factors were investigated for the jobs in nuclear power plants that are operated based on procedures. Especially, the occupational stress scale for Korean employees (KOSS) was developed. The KOSS has 8 subscales by using a factor analysis and validation process in order to measure stress at work and to find methods for the prevention of stressors. In this point of view, the RHRI (Radiation Health Research Institute of KHNP (Korea Hydro and Nuclear Power) assessed how wellsuited employees were for their job during their health examination in 2009. In this study the present condition of employee's stress level is investigated to find a way to manage their stressors

    The usage of digital Instrumentation and Control (I and C) in a nuclear power plant becomes more extensive, including safety related systems. The PSA application of these new designs are very important in order to evaluate their reliability. In particular, Korean Standard Nuclear Power Plants (KSNPPs), typically Ulchin 5 and 6 (UCN 5 and 6) reactor units, adopted the digital safety-critical systems such as Digital Plant Protection System (DPPS) and Digital Engineered Safety Feature Actuation System (DESFAS). In this research, we developed fault tree models for assessing the unavailability of the DESFAS functions. We also performed an analysis of the quantification results. The unavailability results of different DESFAS functions showed that their values are comprised from 5.461E-5 to 3.14E-4. The system unavailability of DESFAS AFAS-1 is estimated as 5.461E-5, which is about 27% less than that of analog system if we consider the difference of human failure probability estimation between both analyses. The results of this study could be utilized in risk-effect analysis of KSNPP. We expect that the safety analysis result will contribute to design feedback

    The transition temperature shift (TTS) of the reactor pressure vessel materials is an important factor that determines the lifetime of a nuclear power plant. The prediction of the TTS at the end of a plant’s lifespan is calculated based on the equation of Regulatory Guide 1.99 revision 2 (RG1.99/2) from the US. The fluence factor in the equation was expressed as a power function, and the exponent value was determined by the early surveillance data in the US. Recently, an advanced approach to estimate the TTS was proposed in various countries for nuclear power plants, and Korea is considering the development of a new TTS model. In this study, the TTS trend of the Korean surveillance test results was analyzed using a nonlinear regression model and a mixed-effect model based on the power function. The nonlinear regression model yielded a similar exponent as the power function in the fluence compared with RG1.99/2. The mixed-effect model had a higher value of the exponent and showed superior goodness of fit compared with the nonlinear regression model. Compared with RG1.99/2 and RG1.99/3, the mixed-effect model provided a more accurate prediction of the TTS.

    International Nuclear Information System (INIS)

    2009-01-01

    The primary objective of the Republic of Korea's energy policy has been to secure an economical and stable supply of energy by diversifying energy sources. At present, environment-friendly energy policies have gained ground due largely to a progress in climate change convention negotiations. The impact of the two oil crises in the 1970s on the Korean economy was severe. In response, the government tried to limit the annual increase in energy consumption to about 7∼8%. By the 1990s, however, consumption was growing at more than 10% annually. The total primary energy consumption increased from 12.0 million TOE in 1965 to 233.4 million TOE in 2006. Due to the scarcity of indigenous energy resources, the Republic of Korea is heavily dependent upon imported energy. The overseas energy dependence continuously rises from 47.5% in 1970 to 96.5% in 2006. As in many other countries that are not endowed with fossil fuel reserves, nuclear power is considered to be the most reliable energy source capable of meeting the soaring energy demand necessary for economic development (i.e. an economic growth rate of some 10% per year). The Republic of Korea has consequently chosen nuclear power as one of its major energy sources

    With the soaring oil price and worsening global warming, nuclear power has attracted considerable attention on a global scale and a new large market of nuclear power plants (NPPs) is expected. The Korean government aims to export up to 10 NPPs by 2012, based on the successful export of 2 NPPs to the UAE in 2009. It is also going to develop a follow-up model of the Advanced Power Reactor (APR) 1400, and join the world's NPP market under the banner of Korea's original reactor type. For this, it promulgated the strategic plan, NuTech 2012, a technology development plan intended for the early acquisition of core technologies for the Korean advanced NPP design and domestic production of the main components in NPP. This paper introduces the strategic plan of NuTech 2012. (orig.)

    We investigated the cross-cultural factorial validity of the three Higher-Order (H-O) scales in the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) among a sample of North Korean female refugees (N = 2,732). Given the importance of the H-O scales in the overall structure of the MMPI-2-RF scales and in interpretation, we were interested in exploring their cross-cultural validity. We conducted an exploratory factor analysis (EFA) on the nine Restructured Clinical (RC) scale raw scores and fitted and compared one- to three-factor models. The three-factor model, akin to the model in Tellegen and Ben-Porath, demonstrated the best fit to the data. Furthermore, the pattern matrices of loadings across the current sample and the U.S. samples were comparable despite some differences, such as the RC2 scale's salient, negative loading on a factor analogous to the Behavioral/Externalizing Dysfunction scale. We also investigated the unique psychological characteristics of the refugees, possibly resulting from the arduous, perilous journeys out of North Korea taken by this group of female refugees and discussed the results of EFA in light of those singular psychological traits and experiences. Overall, the three H-O scales of the Korean MMPI-2-RF evidenced reasonable cross-cultural factorial validity among the sample of North Korean female refugees. © The Author(s) 2014.

    Highlights: • The cyber terror modeling is made by the social networking algorithm. • This is applicable by the social networking service (SNS). • Security of nuclear industry could be controlled by the network theory. • Newly developed complex algorithm can be introduced. • Simplified graphics show the operator easily. - Abstract: Nuclear energy has been studied for the secure power productions, which is based on the simulation study following the incident of nuclear cyber terror attack on South Korean nuclear power plants (NPPs). The social networking is used for the terror incident modeling and its prevention strategies. The nuclear industry could be investigated in the aspect of minimizing the dangerous situations caused by possible terror attacks which are considered by the society oriented connectivity among the related people or groups. The social networking circle by system dynamics diagram (SNCSD) is constructed, where the configuration of a model social networking example by system dynamics (SD) is applied. From A to H regions, the values are obtained by the random numbers incorporated with the designed algorithms. The results show the comparative values of terror possibilities which are based on the proposed social networking algorithm. It is possible to prepare for potential terrorism in the nuclear industry

    The Korean Yonggwang Nuclear Power Plants 3 ampersand 4(YGN 3 ampersand 4) are the two-loop pressurized water reactor (PWR) nuclear steam supply systems, rated at 2,815 MW(thermal). They incorporate the safety injection system (SIS) consisting of the two high pressure (HPSI) pumps, two low pressure safety injection (LPSI) pumps, and four accumulators. The SIS is two headered arrangements, each to four cold legs injection (CLI) type which provides cooling to the core in the highly unlikely event of a loss-of-coolant accident (LOCA). In the current SIS, the LPSI pumps automatically start during a LOCA, and also provide the residual heat removal capability during the shutdown cooling. This paper presents the feasibility of the removal of the LPSI from the existing SIS with minor system changes, including the increase up to four in the HPSI pumps, direct vessel injection(DVI), and the flow-controllable accumulators. A double-ended rupture of one of the four cold legs in the YGN 3 ampersand 4 was simulated using RELAP5/MOD3.1 to determine the feasibility of the application of this new SIS design to the current nuclear power plants. As a result, the calculated reflooding peak cladding surface temperature(PCT) was comparable to that of original base calculation, and the downcomer and the core collapsed liquid level during reflooding were also comparable to those in the current safety system design. This large break, cold-leg LOCA analysis addresses the reflooding capability without credit for a LPSI pump system and the applicability of the new flow-controllable accumulator. Also this analysis confirms that the combination of new flow-controllable accumulators, DVI and the increased HPSI pumps maintain the peak cladding temperature below the prescribed limits. 14 refs., 4 figs., 3 tabs

  17. Introduction of virtual detectors for core monitoring system of korean standard nuclear power plant

    2000-01-01

    A novel algorithm known as the virtual detector method (VDM) is introduced to reconstruct the axial power shape (APS) for the on-line core monitoring system of the Korean Standard Nuclear Power Plant (KSNP). A pure statistical method (SM) is also introduced and the results are compared with the currently implemented five-mode Fourier fitting method (FFM). VDM adopts nine virtual detector informations coupled with a regression model based on the Alternating Conditional Expectation (ACE) algorithm. VDM uses Fourier fitting with the information of nine virtual detectors expanded from the currently implemented FFM, which uses five-level detector information. By introducing virtual detectors, we can increase the number of axial detectors, and thus expect the computational errors of APS to be reduced. The two methods (SM and VDM) are applied to in-core mapping data from six cycles of Yong Gwang nuclear power plant Units 3 and 4. For ∼ 3500 cases of APSs extracted from a cycle of operation which is simulated by a three-dimensional nodal code, the accuracy of the three methods (SM, VDM, FFM) is compared. The average root mean square (RMS) error and average of axial peaking error of SM and VDM resulted in reduction of more than 50 % and 70 %, respectively, relative to FFM. VDM and SM also show more realistic axial profiles and predict more accurate axial peaking than FFM. These improvements can contribute to a larger thermal margin. SM shows the most accurate results for all cases. VDM can almost obtain the same results as SM, and using far fewer computation steps. VDM can be a useful tool for precisely reconstructing axial power shapes in a core monitoring system. (authors)

    Nitschke, J.M.

    1993-05-01

    In 1989 this author proposed the construction of a dedicated, flexible, radioactive nuclear beams facility that would provide intense beams of nearly all elements for a program of scientific studies in nuclear structure, nuclear reaction dynamics, astrophysics, high-spin physics, nuclei far from stability, material- and surface science, and atomic- and hyperfine-interaction physics. The initial name proposed for the new facility was ''IsoSpin Factory'' to underscore the key feature of this new physics tool; it was later changed to ''IsoSpin Laboratory'' (ISL). The ISL is now supported by a broad base of nuclear scientists and has been identified in the US Long Range Plan on Nuclear Science as one of the new potential construction projects for the second part of this decade. Since 1989 a number of conferences and workshops has been held in which the scientific and technical case for RNB facilities has been made. The purpose of this paper is to focus on the North American plan for the ISL, which was initially summarized in a ''White Paper'' but has since evolved in its scientific and technical scop

  19. Korea nuclear exports: Why did the Koreans win the UAE tender? Will Korea achieve its goal of exporting 80 nuclear reactors by 2030?

    Berthelemy, Michel; Leveque, Francois

    2011-01-01

    The success of Korea in winning, in December 2009, a USD 18.6 billion nuclear tender in the United Arab Emirates (UAE) has led to a growing interest in the organization and strengths of the Korean nuclear industry. In this paper, we present the main economic and political factors that explain the success of the Korean consortium. In particular, thanks to an active national program of Nuclear Power Plant (NPP) construction, Korea has developed distinct competitive advantages in terms of low cost, high credibility and high performance. At the same time, due to the important barriers to enter into the nuclear export market in the UAE, Korea has had to sacrifice its profit margin and has benefited from a strong political support from its government through export financing. More importantly, Korea's success is also due to its alliance with Westinghouse and the support of the US diplomacy. Subsequently, we show that while Korea has recently experienced setbacks in nuclear tenders, it will most certainly try to win in the short run a second nuclear tender with another aggressive price. In the longer run, Korea could take a growing share of the international market for NPPs. However, the extent to which Korea can achieve its long term export target will depend upon its capacity to finance nuclear export through export credits and upon the development of its alliance with Westinghouse. It is important to note that this paper was written before the Fukushima nuclear disaster. The scale of the human and environmental consequences of this accident are still unknown, and will undoubtedly have short and long term consequences on nuclear safety requirements and public attitude toward nuclear energy, which will most certainly impact the outlooks for nuclear new-builds.

    This paper describes the work covered and experience gained in the first two years of operation of DERC, a Centre for Decommissioning and Environmental Remediation in the Highlands of Scotland. The Centre is a unique development which was set up to teach nuclear decommissioning as a separate discipline, address the problem of a declining skills base in the field of nuclear technologies and to take advantage of the unique and exceptional innovative, technical and research opportunities offered through the decommissioning of Britain's fast reactor site at Dounreay. The Centre is an offshoot from North Highland College which is a member of UHI, the University in embryo of the Highlands and Islands. The Centre currently supports ten PhD students completing various diverse projects mainly in the field of nuclear environmental remediation. In addition there area number of full and part time MSc students who participate in NTEC (Nuclear Technology Education Consortium) a consortium of British Universities set up specifically to engender interest and skills in nuclear technology at postgraduate level. At undergraduate level, courses are offered in Nuclear Decommissioning and related subjects as part of Electrical and Mechanical degree courses. In addition to our relationship with the United Kingdom Atomic Energy Authority (UKAEA) the Dounreay site licensee, we have links with Rolls-Royce and the Ministry of Defence who also share the Dounreay site and with other stakeholders such as, the UK regulator (HSE/NII), the Scottish Environmental Protection Agency (SEPA), local and international contractors and we liaise with the newly formed Nuclear Decommissioning Authority (NDA), who provide some sponsorship and support. We possess our own equipment and laboratories for taking and analysing soil samples and for conducting environmental surveys. Recently we commissioned an aerial survey of contamination in the locality from natural sources, other background levels such as

    Full Text Available The importance of Korean Peninsula in Russian foreign strategy is based on the need to preserve peace and stability in the Russia's Far East "soft underbelly" and to be a part of international efforts to solve the Korean problem, as well as to promote regional economic cooperation. In 1990-s Russia's position on the peninsula weakened, mainly because of the rupture of ties with North Korea, while relations with South Korea were reactive in nature. Rebalancing relations with the two Koreas in 2000-s increased Russia's involvement into Korean settlement, including the 6- party format. Russia/s relations with North Korea are now based on good neighborhood principle, however, they are far from idyllic as Russia disapproves of Pyongyang's behavior, especially its nuclear and missile activities. However to influence the situation more Russia should deepen its ties with the current Pyongyang leadership regardless of how irritating its behavior might be. Relations with the ROK are aimed at becoming strategic, but in reality are limited due to ROK's alliance with the USA. However South Korea has become the third most important economic partner in Asia. Russia is especially interested in three- party projects, such as Trans-Korean railroad (linked to Transsiberan transit way, gas pipeline and electricity grid. However implementation of these project is negatively influenced by the tensions in Korean peninsula. It can be solved only by multilateral efforts for comprehensive solution combining security guarantees for North Korea and its abandonment of nuclear option.

    Westinghouse developed and connected emergency operating procedures into a set of FLEX Support Guidelines(FSGs). This paper explains that Korean WH(Westinghouse) type nuclear power plants develop emergency operating strategies for ELAP(extended loss of all AC power), which include guidelines to use permanent and portable equipment as necessary to prevent core damage until AC power is restored from a reliable alternate source of AC power. The Korean emergency operating response strategies were developed to cope with a ELAP such as Fukushima event. The strategies include guidelines to prevent fuel damage using the FLEX equipment. Operators should take actions to prepare FLEX equipment within license basis SBO coping time. The loss of all AC power has been analyzed to identify the behavior of major NSSS process variables using RELAP computer code. The accident analysis showed that the plant does not result in fuel damage in 72 hours after an ELAP if operators take actions to cool RCS with opening of SG ADV in 5 gpm seal leak case. In this scenario, because ELAP is in process and all power cannot be used, operator should operate the FLEX equipment in order to actuate active equipment using the EOP fo SBO response. This strategy will prevent entering SAMG because this actions result in core cooling and stay in core exit temperature less than 650 .deg. C. Korean emergency operating guidelines(EOGs) will be developed using this strategies for response to the BDBEE.

    Democratic People's Republic of Korea(DPRK) carried out 6th nuclear test on 3 Sep. 2017 at 03:30 UTC. Korea Meteorological Administration(KMA) announced to the public that the event took place in the DPRK's test site, Punggye-ri with the magnitude 5.7. This event is larger than previous one in terms of magnitude and showed that measured magnitude strongly depends on the frequency band of data. After we applied several magnitude scales such as Everdon(1967), Nuttli(1967), and Hong & Lee(2012) to this event, we found that magnitude ranges from 5.3 to 6.7 which depends on frequency band and epicentral distance of signal. 6th DPRK test experiment indicated that spectral amplitude ratio of 6th/5th near 2.37 Hz shows similar amplification compatible to relative spectral magnitude 5.7, while spectral amplitude ratio of 6th/5th near 1.0 Hz marks relative spectral magnitude about 6.1. Relative spectral magnitude varies with frequencies and decreases as frequency increase. We found that systematic non-linearity exists for spectral amplitude ratio of 6th/5th from 1.0 to 10.0 Hz, while it's characteristic is not found at 5th/4th and 4th/3th. A methodology is presented for determining mb(Pn) magnitude of underground nuclear explosions from local Pn phase. 582 waveforms from vertical component of broadband and acceleration seismographs at 120 stations in the epicenter distance from 340 to 800 km are used to calibrate mb(Pn) magnitude scaling for DPRK's nuclear tests. The mb(Pn) estimates of regional events for Korean Peninsula are determined to be mb(Pn) ? = log10(A) + 2.1164×log10(d) - 0.2721, where A is the peak-to-peak Pn amplitude in μm and d is the epicentral distance in km. Systematic non-linearity does not observed at frequency band from 0.1 to 1.0 Hz. The magnitude of 6th event is mb(Pn) 6.08 and mb(Pn) 4.52, 4.92, 4.84 and 5.03 for 2nd, 3rd, 4th and 5th respectively. Further research of applicable mb(Pn) magnitude scaling is required for all frequency band and

  5. A study on the food consumption rates for off-site radiological dose assessment around Korean Nuclear Power Plants

    The internal dose by food consumption mostly accounts for radiological dose of public around Nuclear Power Plants (NPPs). But, food consumption rates applied to off-site dose calculation in Korea which are the result of field investigation around Kori NPP by the KAERI (Korea Atomic Energy Research Institute) in 1988, are not able to reflect the latest dietary characteristics of Korean. The food consumption rates to be used for radiological dose assessment in Korea are based on the maximum individual of US NRC (Nuclear Regulatory Commission) Regulatory Guide 1.109. However, the representative individual of the critical group is considered in the recent ICRP (International Commission on Radiological Protection) recommendation and European nations' practice. Therefore, the study on the re-establishment of the food consumption rates for individual around nuclear power plant sites in Korea was carried out to reflect on the recent change of the Korean dietary characteristics and to apply the representative individual of critical group to domestic regulations. The ministry of Health and Welfare Affairs has investigated the food and nutrition of nations every 3 years based on the Law of National Health Improvement. The statistical data such as mean, standard deviation, various percentile values about food consumption rates to be used for the representative individual of the critical group were analyzed by using the raw data of the national food consumption survey in 2001∼2002. Also, the food consumption rates for maximum individual are re-estimated

    Cytogenetic and hematological analysis was performed on the peripheral blood lymphocytes (PBLs) obtained from Korean native goats bred in two nuclear power plants (Wolsong and Uljin) and a control area. The frequencies of gamma-ray-induced micronuclei (MN) in the cytokinesis-blocked (CB) lymphocytes at several doses were measured in three Korean native goats. The measurements performed after irradiation showed dose-related increases in the MN frequency in each of the donors. The results were analyzed using a linear-quadratic model with a line of best fit of y=0.1019D+0.0045D 2 +0.0093 (y=number of MN/GB cells and D=irradiation dose in Gy). The MN rates in the goats from the Wolsong and Uljin nuclear power plant, and the control area were 9.60±2.88, 6.83±1.47 and 9.88±4.32 per 1,000 CB lymphocytes, respectively. The apparent difference is not statistically significant. The MN frequencies of PBLs from goats bred in three areas means that the values are within the background variation in this experiment. The MN frequencies and hematological values were similar regardless of whether the goats were bred in the nuclear power plant or the control area. (author)

  7. The role of nuclear energy for Korean long-term energy supply strategy : application of energy demand-supply model

    An energy demand and supply analysis is carried out to establish the future nuclear energy system of Korea in the situation of environmental restriction and resource depletion. Based on the useful energy intensity concept, a long-term energy demand forecasting model FIN2USE is developed to integrate with a supply model. The energy supply optimization model MESSAGE is improved to evaluate the role of nuclear energy system in Korean long-term energy supply strategy. Long-term demand for useful energy used as an exogeneous input of the energy supply model is derived from the trend of useful energy intensity by sectors and energy carriers. Supply-side optimization is performed for the overall energy system linked with the reactor and nuclear fuel cycle strategy. The limitation of fossil fuel resources and the CO 2 emission constraints are reflected as determinants of the future energy system. As a result of optimization of energy system using linear programming with the objective of total discounted system cost, the optimal energy system is obtained with detailed results on the nuclear sector for various scenarios. It is shown that the relative importance of nuclear energy would increase especially in the cases of CO 2 emission constraint. It is concluded that nuclear reactor strategy and fuel cycle strategy should be incorporated with national energy strategy and be changed according to environmental restriction and energy demand scenarios. It is shown that this modelling approach is suitable for a decision support system of nuclear energy policy

    The structure of the US utility industry is in transition. Political, social, and economic factors are contributing to a rapid shift from a monopoly structure (captive markets, cost-plus prices, negotiated rate of return on capital) to a highly competitive one (choices for customers, prices determined by the market place, earnings based on market price less cost). The rate of change has been accelerating. For example, what just two years ago would have been thought of as highly unlikely -- competition for the individual electric customer -- is now part of the plan in California and other states. In our view, technology is at the root of many of these structural changes with more to come. Yet another round of technological change is afoot, involving even more efficient gas turbines, new methods of utilizing transmission lines, distributed generation, and new opportunities for electricity use and service. It can be argued that the restructuring of the marketplace reflects, in some measure, anticipation for these advances. For the foreseeable future, nuclear energy will continue to play a significant role in the generating grid of North America. However, new nuclear generation will be held to standards of competition that are dictated by market forces, and by advances in competing technologies for base load generation. It is important to understand these forces, and devise a response which ensures that nuclear energy will continue to provide a viable, competitive, and environmentally superior option for generating electricity in the 21st century. The EPRI Nuclear Power program is focused on achieving these goals. (author)

    Calculations have been made to estimate the generation of SNF including Plutonium (Pu) and minor actinides (MAs) from PWR and PHWR NPPs by using the IAEA code Nuclear Fuel Cycle Simulation System (NFCSS) for the period of 2016, 2030 as 12 more NPPs will be added by the year 2029. In order to find the optimize option for SNF management through sustainable use of nuclear energy system and reduce the associated radiological risk, 4 scenarios to burnout the Pu and MAs are analyzed. Estimation for the amount of SNF including major radionuclides has made for the year of 2016, 2030, 2089 and 2109 with an approximate amount of 148,19.65MT, 248,34.6 MT, 41572.23 MT and 61272.24 MT of SNF will be generated respectively. Radioactivity and radiotoxicity is calculated in order to access the radiological risk in terms of ingestion. Four Transmutation strategies is predicted to make Korean NPPs sustainable by incorporating KALIMER-600 (Burner) reactor in Korean nuclear fleet with an approximate transmutation rate of 99.77%, 96.57%, 95.34% and 97.58% for MA only (scenario-1), (MA & Pu) scenario-2, scenario-3 (MA only till the year 2125) and scenario-4 MA & Pu till the year 2148) respectively.

    North Korea has chosen nuclear weapons as the means to protect its sovereignty. Despite international society's endeavors and sanctions to encourage North Korea to abandon its nuclear ambition, North Korea has repeatedly conducted nuclear testing. In this paper, the reason for North Korea's addiction to a nuclear arsenal is addressed within the framework of cognitive psychology. The prospect theory addresses an epistemological approach usually overlooked in rational choice theories. It provides useful implications why North Korea, being under a crisis situation has thrown out a stable choice but taken on a risky one such as nuclear testing. Under the viewpoint of prospect theory, nuclear tests by North Korea can be understood as follows: The first nuclear test in 2006 is seen as a trial to escape from loss areas such as financial sanctions and regime threats; the second test in 2009 was interpreted as a consequence of the strategy to recover losses by making a direct confrontation against the United States; and the third test in 2013 was understood as an attempt to strengthen internal solidarity after Kim Jong-eun inherited the dynasty, as well as to enhance bargaining power against the United States. Thus, it can be summarized that Pyongyang repeated its nuclear tests to escape from a negative domain and to settle into a positive one. In addition, in the future, North Korea may not be willing to readily give up its nuclear capabilities to ensure the survival of its own regime.

    The prime ministers of North Korea and South Korea adopted 'Joint Declaration of the Denuclearization of the Korean Peninsular' (Joint Declaration) on December 31, 1991. Unprecedented as an agreement between two political powers of a divided country, this Joint Declaration is important for its historical significance. To analyze the denuclearization policy in the Korean peninsular, this dissertation suggests a framework which can be established on the factors facilitating the denuclearization both on the level of international politics and on the politics of a divided country. A substantial nuclear proliferation theory should be based on the study in detail of the nuclear proliferation cases of about 40 individual countries. This dissertation may be meaningful as a concrete study of the denuclearzation in the Korean peninsular on theoretical and practical basis

    Colors are widely used to warn risk levels and to attract attention of the public. Korea Standard Nuclear Reactor Control Room (KSNRCR) also uses several colors to differentiate warnings, priorities, status, borders, and messages based on the HF010 guideline. However the previous studies showed that the general public not engaged in a specific job domain had different associations of colors as regulated in the standards or the guidelines. It is also expected that the general public not engaged in nuclear power plant industry will have different color association system from the color coding system applied to the KSNRCR. So, this study was performed to show whether there is any difference between color association of a sample Korean group and the color meanings specified in the HF010 guideline. The general public not engaged in the nuclear power plant industry have no idea of the color usage in the nuclear control room. So we converted the specific color usage situation into similar but general situations. In questionnaire, we gave subjects the general situation where color coding is appled and alternative colors which were applied to the HF010 guidelines. And we asked the subjects to choose the colors proper to the situation and to rank the colors according to the degree of suitability. A hundred college students participated in the experiment. 10 refs., 7 tabs. (Author)

South Korea, rather than pursuing nuclear weapons capability like North Korea, has worked hard to produce a rapidly expanding nuclear powered electricity supply industry, which is described. Government targets which aim to meet predicted increases in demand for electricity are noted, but the problems of waste management and reprocessing have yet to be solved. (UK)

    The author discusses the frustrations of the international community in dealing with North Korea after negotiation of the Nuclear Non-proliferation treaty. In the past, the international community has not been well prepared to deal with the North Korean obstinacy. It has repeatedly misjudged North Korean goals, South Korean Interests, and Japanese reactions. A new approach is proposed for the long run, that avoids coercion or appeasement. Economic incentives are suggested as the means to bring about changes in North Korean attitudes that will ultimately foster the desire for maintaining economic stability and well being rather than warlike independence. China and the former Soviet Union are not considered supportive of a warlike posture in North Korean but are making economic overtures to South Korea themselves. If the economic approach proves successful, it will enhance the chances of Korean unification by peaceful means and under democratic rule because time is on the side of democracy. In the long run nonproliferation will be achieved through unification.

    Full-scale use of a microprocessor-based digital instrumentation and control (I and C) system for the control of nuclear power plants (NPPs) in Korea has spanned >14 yr and has covered eight plants. Experience gained from these applications is substantial. In this paper, the discussion centers on the design experience of the data communication portion of the digital I and C system along with the associated nuclear licensing issues. The data communication designs of the eight plants (four operating and four under construction) have changed from project to project and from supplier to supplier. The first two of the eight plants, Yonggwang NPP (YGN) Units 3 and 4 (YGN-3 and 4) included only the on/off (binary) controls in the digital I and C system. The subsequent six plants had a fully expanded scope of plant controls including both on/off controls as well as continuous (analog) controls. These latter six plants are Ulchin NPP (UCN) Units 3 and 4 (UCN 3 and 4), YGN Units 5 and 6 (YGN 5 and 6), and UCN Units 5 and 6 (UCN 5 and 6) in the order of their construction start dates. The digital system suppliers are Forney for YGN 3 and 4 and UCN 5 and 6; and Eaton for UCN 3 and 4 and YGN 5 and 6. The Forney system uses bus network architecture, while the Eaton system is based on a ring network configuration. The design differences, advantages, disadvantages, and specific licensing issues of these two configurations unique to the NPP operating environment are discussed in the abstract. The discussions are organized into two parts: the Forney system of YGN 3 and 4 and the Eaton system of YGN 5 and 6. The Forney system of UCN 5 and 6 is still in its early stage of design and manufacture, and it is basically similar to the design of YGN 3 and 4 except for the system upgrade from a 16- to a 32-bit system and the addition of an analog plant monitoring and control function. The Eaton system of UCN 3 and 4 is essentially identical to that of YGN 5 and 6 except that the YGN 5 and 6

    Questions of whether past nuclear regulatory body of Korea is not a proper system to monitor and check the country's nuclear energy policy and utilization have been raised. Moreover, a feeling of insecurity regarding nuclear safety after the nuclear accident in Japan has spread across the public. This has stimulated a renovation of the nuclear safety regime in Korea. The Nuclear Safety and Security Commission (NSSC) was launched on October 26, 2011 as a regulatory body directly under the President in charge of strengthening independence and nuclear safety. This was a meaningful event as the NSSC it is a much more independent regulatory system for Korea. However, the NSSC itself does not guarantee an enhanced public acceptance of the nuclear policy and stable use nuclear energy. This study introduces the new NSSC system and its details in terms of organization structure, appropriateness of specialty, budget stability, and management system. (authors)

    The precise prediction of radiation embrittlement of aged reactor pressure vessels (RPVs) is a prerequisite for the long-term operation of nuclear power plants beyond their original design life. The expiration of the operation licenses for Korean reactors the RPVs of which are made from SA533B-1 plates and welds is imminent. Korean regulatory rules have adopted the US Nuclear Regulatory Commission's transition temperature shift (TTS) models to the prediction of the embrittlement of Korean reactor pressure vessels. The applicability of the TTS model to predict the embrittlement of Korean RPVs made of SA533B-1 plates and welds was investigated in this study. It was concluded that the TTS model of 10 CFR 50.61a matched the trends of the radiation embrittlement in the SA533B-1 plates and welds better than did that of Regulatory Guide (RG) 1.99 Rev. 2. This is attributed to the fact that the prediction performance of 10 CFR 50.61a was enhanced by considering the difference in radiation embrittlement sensitivity among the different types of RPV materials.

    In severe accident, the molten corium would discharge into the reactor cavity and interact with water and concrete of cavity. Molten corium includes non-oxidation metals such as Zr, Fe and Cr. These metal species reacted with water emit hydrogen gas. In addition to this, a mount of steam can be emitted to the containment such as steam line break accident. As a result, steam and hydrogen gas can pressurize containment over the design pressure and threaten its integrity. For this reasons, a concept equipped with finned on the containment building was proposed for coping with prolonged accident. Finned containment can enhance heat transfer to the ambient, and the building itself is working as a heat sink. Multiple metal fins and metal rod are penetrated into containment wall, and the rods are working as an additional path of heat removal. To be accepted in the nuclear power plants, this configuration should satisfy the requirement of heat removal and follow all regulations related with containment also. For applying to Korean nuclear power plants, the finned containment should follow all regulations specialized in Korea such as Nuclear regulatory criteria for light water reactor and Guidelines of nuclear safety examination for light water reactor. A concept of containment as a passive cooling system has been proposed. Furthermore, the new containment concept can be applied on the real containment which satisfies the various regulations. Finned containment would be expected positive effects on heat removal from the containment. If the fins are properly welded to the liner, finned containment could satisfy the leak tightness and prevention of external influences. Finned containment could be favorable to protect external impact like aircraft crash because of the additional structural integrity by the fins

    A Korean radioecology model to simulate radionuclide behavior in agricultural ecosystems has been developed as a module for evaluating the ingestion dose in a Korean real-time dose assessment system FADAS, which evaluates the comprehensive radiological consequences in an accidental release of radionuclides to the environment. Using the predictive results of a Korean radioecology model, a methodology for the optimization of countermeasures has been designed based on a cost-benefit analysis. In this manuscript, a Korean radioecology model including agricultural countermeasures was introduced, and discussed with the sample calculations for the postulated accidental release of radionuclides to the environment.

    Today, policies relating to nuclear power generation face a myriad of issues regarding the aspects of understanding, sympathy, acceptance, and satisfaction by policy consumers. This study has provided education on nuclear power for elementary, middle, and high school students who are expected to have high ripple effects of communication and education, and organized a mock referendum on nuclear power generation to observe the results of the referendum. Based on the results of this study, it is important to provide sufficient information on the dangers of nuclear power to the future generation in order to enable them to participate in policies with the right value judgments. Both before and after the educational program, all of elementary, middle, and high school students overwhelmingly indicated that nuclear power was dangerous in presenting their disagreement. The expert groups must consider that students are concerned about the risks of nuclear power generation, despite the explanations from experts on the safety of nuclear power.

    South Korea is an important case study for understanding the future role of nuclear power in countries with on-going economic growth, and limited renewable energy resources. We compared quantitatively the sustainability of two ‘future-mapping’ exercises (the ‘Governmental’ scenario, which relies on fossil fuels, and the Greenpeace scenario, which emphasises renewable energy and excludes nuclear power). The comparison was based on a range of environmental and technological perspectives, and contrasted against two additional nuclear scenarios that instead envisage a dominant role for nuclear energy. Sustainability metrics included energy costs, external costs (greenhouse-gas emissions, air pollutants, land transformation, water consumption and discharge, and safety) and additional costs. The nuclear-centred scenarios yielded the lowest total cost per unit of final energy consumption by 2050 ($14.37 GJ −1 ), whereas the Greenpeace scenario has the highest ($25.36 GJ −1 ). We used probabilistic simulations based on multi-factor distributional sampling of impact and cost metrics to estimate the overlapping likelihoods among scenarios to understand the effect of parameter uncertainty on the integrated recommendations. Our simulation modelling implies that, despite inherent uncertainties, pursuing a large-scale expansion of nuclear-power capacity offers the most sustainable pathway for South Korea, and that adopting a nuclear-free pathway will be more costly and produce more greenhouse-gas emissions. - Highlights: • Nuclear power has a key role to play in mitigating greenhouse-gas emissions. • The Greenpeace scenario has higher total external cost than the nuclear scenarios. • The nuclear-centred scenarios offer the most sustainable option for South Korea. • The similar conclusions are likely to apply to other Asian countries

I argue that if he experiences fear and believes that he has some...... control over whether these extreme events actually happen, he will moderate his nuclear threats and behave more like other experienced nuclear powers. But if he experiences fear and believes that he has no control, he will likely pursue policies that could cause nuclear war. I use this insight...

    China, India and USA (nuclear adopted countries) are planning tremendous number of NPPs to meet their increasing electricity demand and Saudi Arabia, Vietnam (nuclear adopting countries) are also planning to include nuclear power in their energy mix as a long-term plan. Korea has exported 4 units of APR1400 to the UAE in December, 2009. Korea became sixth NPP supplier country and our economic feasibility and safety features were started to evaluate worldwide. Nuclear industries became a new driver of Korea’s export and nuclear industries in Korea are now expecting another NPP export to Middle-eastern countries, including UAE and Saudi Arabia, based on the first-mover’s advantage at the UAE. In 2000s, five countries (Japan, USA, France, Russia and Korea), which are able to build NPP, focused on NPP export more than domestic construction. Global trend of world nuclear market changed rapidly, especially after NPP export to the UAE. By the global trend, hegemony of nuclear market migrated from supplier country to buyer country. Nuclear companies started cooperating rather than competing. Financing to developing countries become more important. In general, one of the considerable combinations is Korea-Japan-USA alliance. Korea is in charge of EPC, Japan supports financing and deficient technology (with USA partner), and Japan-USA handles fuel supply and back-end fuel cycle based on new agreed terms of ROK-US Nuclear Cooperation Agreement. This combination was judged to best way to collaborate with global companies. Paying attention to many delayed (or potentially delayed) constructions from Russia, intercepting the construction work will be available in case of contracted countries. Korea can emphasize the short construction time, high responsiveness and mild/equal diplomatic position to the target countries

    Full Text Available To identify the feasibility of disposing of spent activated carbon as a clearance level waste, we performed characterization of radioactive pollution for spent activated carbon through radioisotope analysis; results showed that the C-14 concentrations of about half of the spent activated carbon samples taken from Korean NPPs exceeded the clearance level limit. In this situation, we selected thermal treatment technology to remove C-14 and analyzed the moisture content and thermal characteristics. The results of the moisture content analysis showed that the moisture content of the spent activated carbon is in the range of 1.2–23.9 wt% depending on the operation and storage conditions. The results of TGA indicated that most of the spent activated carbon lost weight in 3 temperature ranges. Through py-GC/MS analysis based on the result of TGA, we found that activated carbon loses weight rapidly with moisture desorption reaching to 100°C and desorbs various organic and inorganic carbon compounds reaching to 200°C. The result of pyrolysis analysis showed that the experiment of C-14 desorption using thermal treatment technology requires at least 3 steps of heat treatment, including a heat treatment at high temperature over 850°C, in order to reduce the C-14 concentration below the clearance level.

These statements have special significance if applied to the situation in North-East Asia and particularly Korean Peninsula. Even under the circumstances of the continued existence of the United States Nuclear Threat, the Government of North Korea has concluded a safeguards agreement and has been inspected by IAEA, thus indicating constant effort to denuclearize the Korean peninsula

    Full Text Available North Korean politics appears neither irrational nor unpredictable: the logic of its actions may at first seem opaque, but it nonetheless displays its own rationale and patterns. – North Korea: a ruthless political actor, now under the leadership of Kim Jong-Un who inherited the regime’s leadership from his father and "Supreme Leader", Kim Jong-Il, in 2011. The country’s policy is based on its ongoing political agenda of (nuclear brinkmanship, a true threat to the world – or at least that's how the Western hemisphere sees it. Yet our factual knowledge of this post-Leninist and totalitarian regime is extremely limited and relatively distorted; it is largely circumstantial evidence and judgmental speculation that accounts for our perception of this East Asian state. Northeast Asia (China, Japan, South and North Korea, Taiwan is a region dominated by the legacy of the Cold War. The North Korean leadership has indeed established its priorities, primarily its isolationist orientation, but in the long term the regime cannot survive without external stimulus. Most importantly, even in a long-term, non-violent and gradual transformation of North Korea considerable danger can ultimately result in the demise of the regime. Apart from few signs of a North Korean "civil society", currently only the army might have the resources to see through a regime change. In the meantime, the strategies of isolationism as well as tight control of the media remain as fundamental cornerstones of the regime. A close-knit network of social control has been established and access to the internet for the most part is limited to the regime’s entrusted cadre.

  20. Development of new NSSS thermal-hydraulic model for Korean standard nuclear power plant(UCN-3/4) simulator

    2001-09-01

    The NSSS thermal-hydraulic programs installed in the domestic full-scope power plant simulators were provided in early 1980s by foreign vendors. Because of limited computational capability at that time, they usually adopt very simplified physical models for a real-time simulation of NSSS thermal-hydraulic phenomena, which entails inaccurate results and the possibility of so-called 'negative training', especially for complicated two-phase flows in the reactor coolant system. To resolve the problem, we developed a realistic NSSS T/H program (named 'ARTS-UCN' code) for the improvement of the Korean Standard Nuclear Power Plant full-scope simulator. ARTS Code, developed as an NSSS T/H model for the KNPEC no. 2 simulator using the RETRAN03 code, was selected as a reference code for ARTS-UCN code development. For the development of ARTS, the followings have been performed: - Improvement of the robustness of RETRAN - Improvement of the real-time simulation capability of RETRAN - Optimum input data generation for the NSSS simulation - New model development that cannot be efficiently modeled by RETRAN - Assessment of the ARTS code. The systematic assessment of ARTS has been conducted in both personal computers (Windows 98, Visual fortran) and the simulator development environment (Windows NT, GSE simulator development tool). The results were resonable in terms of accuracy, real-time simulation and robustness

  1. Rogue proliferator? North Korea's nuclear fuel cycle and its relationship to regime perpetuation

    International Nuclear Information System (INIS)

    Habib, Benjamin

    2010-01-01

    North Korea is unlikely to relinquish its nuclear program because of its importance to the perpetuation of the Kim regime. This conclusion arises from the observation that the nuclear program has been a long-term project spanning several decades, culminating in denuclearisation negotiations, which have followed a cyclical pattern in which the North has provoked crises to extract concessions and gain leverage vis-a-vis regional states. It is clear that the nuclear program has great intrinsic value to Pyongyang. First, this paper argues that the sunk costs of previous investment in the nuclear program, as evidenced by the infrastructure for the country's nuclear fuel cycle, create forward momentum favouring continuation of the nuclear program. Second, it argues that the nuclear program solidifies Kim regime rule as an institutional buttress, as a prop for the domestic economy, and as a vehicle for ideological legitimation. The paper is a unique contribution, which explicitly links the Kim regime's proliferation calculus to the economic and bureaucratic imperatives of regime perpetuation, as well as the sunk cost of previous investment in the nuclear program. It provides a coherent explanation for North Korea's consistent unreliability in negotiations, and offers insights into future prospects of the denuclearisation process.

It includes two nuclear powers recognised by the Non-Proliferation Treaty (Russia and China), a proliferating state (North Korea) and three countries that could very quickly complete nuclear programmes (Japan, South Korea and Taiwan). Now that the question of nuclear proliferation has again surfaced on the international strategic scene, and that North Korea's test of October 2006 has introduced a new security paradigm into the region, how real is the risk of nuclear proliferation in North-East Asia?

    Tensions on the Korean Peninsula remain high despite a long-term strategy by South Korea to increase inter-Korean exchanges in economics, culture, sports, and other topics. This is because the process of reconciliation has rarely extended to military and security topics and those initiatives that were negotiated have been ineffective. Bilateral interactions must include actions to reduce threats and improve confidence associated with conventional military forces (land, sea, and air) as well as nuclear, chemical, and biological activities that are applicable to developing and producing weapons of mass destruction (WMD). The purpose of this project is to develop concepts for inter-Korean confidence building measures (CBMs) for military and WMD topics that South Korea could propose to the North when conditions are right. This report describes the historical and policy context for developing security-related CBMs and presents an array of bilateral options for conventional military and WMD topics within a consistent framework. The conceptual CBMs address two scenarios: (1) improved relations where construction of a peace regime becomes a full agenda item in inter-Korean dialogue, and (2) continued tense inter-Korean relations. Some measures could be proposed in the short term under current conditions, others might be implemented in a series of steps, while some require a higher level of cooperation than currently exists. To support decision making by political leaders, this research focuses on strategies and policy options and does not include technical details.

    Through benchmarking using the excellent record of the nuclear power plants under operation in the United States and Europe and with the continuous development of nuclear-related technology, the Korea Hydro and Nuclear Power Co., LTD (KHNP) reached an average planned preventive maintenance period of 29.6 days in 2009. In addition, KHNP plans to reduce the planned preventive maintenance period at Korea standard nuclear plants (KSNPs) from 29.6 days to less than 21 days by 2014 through a combination of domestic research and development (R and D) and the introduction of the technical know-how applied in the very best overseas nuclear power plants (NPPs). Accordingly, it is necessary to reduce the inspection and maintenance periods of an emergency diesel generator (EDG), which are currently set in the planned preventive maintenance period. If the condition-based predictive maintenance (CBM) technology is applied to EDG engines, the maintenance period of an EDG will be shortened because engine maintenance is accomplished according to the engine condition under this plan. In this study, in the series of CBM program developments which will be applied to EDG engines, the development results of condition diagnosis logic to be applied to EDG engines for exiting domestic NPPs are introduced

    Full Text Available This paper, mainly based on literature and documents from North Korea and Russia, described how health care system had been formulated during the period of between liberation from Japanese Occupation and formation of its own government in North Korea, which is so-called 'the Period of People's Democracy'.North Korea authorities, by themselves, address that their health care system is characterized by state medicine, universal free medical care, emphasis on preventive medicine, community(ho doctors in charge, provisions of modern medical services in parallel with traditional ones, imposed high value on ideologies of medical personnel, and mass participation of health programs so on, taken rise since this period.Under North Korea's socialistic regime, authorities started to restructure health care system through national health care organizations and institutes, which partially provided medical service free. Also, they emphasized preventive medicine against 'capitalistic' treatment-oriented medicine, and community(ho doctor in-charge was derived from this period.It showed that the mass participation on health program was equal hereafter and they had under bias toward more emphasis on ideology of medical personnel rather than their professionalism. The attempt to develop traditional medicine had been made during this period, however, much funding and support was not observed.In this period, it showed that a series of action to restructure health care system had been gradually carried out.

    Care system; Radiological Emergency Supporting System. Environmental radiology level is the main aspect that should be concerned deal with the utilization of nuclear energy. The usage of informational technology in nuclear area gives significant contribution to anticipate and to protect human and environment. Since 1960, South Korea has developed environment monitoring system as the effort to protect the human and environment in the radiological emergency condition. Indonesia has possessed several nuclear installations and planned to build and operate nuclear power plants (PLTN) in the future. Therefore, Indonesia has to prepare the integrated system, technically enables to overcome the radiological emergency. Learning from the practice in South Korea, the system on the radiological emergency should be prepared and applied in Indonesia. However, the government regulation draft on National Radiological Emergency System, under construction, only touches the management aspect, not the technical matters. Consequently, when the regulation is implemented, it will need an additional regulation on technical aspect including the consideration on the system (TSS), the organization of operator and the preparation of human resources development of involved institution. For that purpose, BAPETEN should have a typical independence system in regulatory frame work. (author)

    According to the Operational Performance Information System (OPIS) which has been operated to improve the public understanding by the KINS (Korea Institute of Nuclear Safety), unintended trip events by mainly human errors counted up to 38 cases (18.7%) from 2000 to 2011. Although the Nuclear Power Plant (NPP) industry in Korea has been making efforts to reduce the human errors which have largely contributed to trip events, the human error rate might keep increasing. Interestingly, digital based I and C systems is the one of the reduction factors of unintended reactor trips. Human errors, however, have occurred due to the digital based I and C systems because those systems require new or changed behaviors to the NPP operators. Therefore, it is necessary that the investigations of human errors consider a new methodology to find not only tangible behavior but also intangible behavior such as organizational behaviors. In this study we investigated human errors to find latent factors such as decisions and conditions in the all of the unintended reactor trip events during last dozen years. To find them, we applied the HFACS (Human Factors Analysis and Classification System) which is a commonly utilized tool for investigating human contributions to aviation accidents under a widespread evaluation scheme. The objective of this study is to find latent factors behind of human errors in nuclear reactor trip events. Therefore, a method to investigate unintended trip events by human errors and the results will be discussed in more detail.

    The progress regarding weapons of mass destruction (WMD) programmes in North Korea and the instability on the Korean Peninsula have taken a back seat in the international community's analysis and perhaps its concerns for more than a year. The last event to provoke a wave of protest and tangible renewed interest occurred on 12 February 2013 when Pyongyang carried out its third nuclear test with an estimated yield of 6 to 8 kilo-tonnes. The United Nations Security Council condemned the test on 7 March (Resolution 2094). With the exception of several recent Security Council declarations, it is clear that activity on the part of the international community has been sparse. The same can be said with regard to the European Union and the United States. This state of affairs is not surprising. The analysis takes note of it by ceasing, there or thereabouts, to produce new material. Firstly, the North Korean crisis is a long-term one and the diplomatic process that is meant to lead to its resolution has been interrupted; the Six-Party Talks have been at a standstill since the end of 2008. A agreement between the United States and North Korea, concluded on 29 February 2012 under which the North Korean regime accepted the principle of a moratorium on long-range missile tests, nuclear tests, and all activity at the Yongbyon nuclear complex lastly barely a few days. Many actors involved in the management of this crisis are suffering from a weariness whose acknowledgement is politically incorrect: with regard to Pyongyang's launch of missiles and rockets last spring, the U.S. admiral Samuel Locklear told the Associated Press in July 'you become somewhat numb, you start to say, well, it's not so much of a big deal'. Moreover, since 2013, the focus of international security with regard to WMD and beyond has also largely shifted from North-East Asia to the Middle East and Eastern Europe. Pell-mell, the worsening and broadening of the war in Syria, the terrorist surge in Iraq, the

    The conventional approach for monetary valuation of NPP accident consequence consists of calculating the expected value of various accident scenarios. However, the main criticism of the conventional approach is that there is a discrepancy between the social acceptability of the risk and the estimated expected value of NPP accident. Therefore, an integrated framework for the estimation of the external cost associated with an NPP accident considering the public risk aversion behavior was proposed in this study based on the constructed theoretical framework for estimating both the value of statistical life (VSL) and the risk aversion coefficient associated with an NPP accident to take account of the accident cost into the unit electricity generation cost of NPP. To estimate both parameters, an individual-level survey was conducted on a sample of 1,364 participants in Korea. Based on the collected survey responses, both parameters were estimated based on the proposed framework and the external cost of NPP accident was estimated based on the consequence analysis and considering the direct cost factors for NPP accident. Internalization of external costs into the comprehensive energy production cost has been considered as a potentially efficient policy instrument for a more sustainable energy supply and use. However, the internalization of externalities, such as public health damage, have raised a number of generic policy issues in a nuclear energy sector, with specific challenges resulting from the distinct characteristics of external cost estimation. Especially, the major challenge remained to address the public safety concerns regarding a nuclear accident, which can be specified as low-probability high-consequence accident, driven by the aspects of public risk aversion.

    In order to decide an optimum countermeasure against farmland contaminations following a severe NPP accident, it is necessary to have a reliable tool for predicting the concentrations of radiocesium in crop plants. For the estimation of radionuclide concentrations in crop plants, various transfer parameters, which quantify the radionuclide transfer from one compartment to the next, are used in general. Some amount of transfer parameter data has been produced at the Korea Atomic Energy Research Institute (KAERI) over the last 30 years. The present work was conducted to collate the KAERI data on radiocesium in staple food crops and to suggest effective ways of using them for assessing the environmental impact of a nuclear accident. The transfer parameter values of radiocesium for rice, Chinese cabbage and radish varied considerably with soils and times of its deposition. The proposed representative values were mostly based on a limited amount of data so they cannot be considered to have a high representativeness. Accordingly, they are intended for provisional use and a continuous improvement should be made. It is necessary to produce a sufficient amount of additional domestic data on the indirect pathway by conducting root-uptake experiments with as many types of soil as possible

    2011-01-01

    Addressing issues of renewable energy in North Africa must incorporate concerns regarding the compatibility of energy mixes with the nature of political regimes, their geopolitical relevance, and their socio-economic effects, in addition to economic cost-benefit deliberations. One important and under-researched aspect of nuclear energy refers to the trade-off between socio-economic development and political power conservation. Competing interests in North Africa's energy market as well as aspects of regional cooperation capacity are important when assessing the choice between renewable and nuclear energy. Therefore, the future course of meeting North Africa's energy needs is subject to a complex political and economic interplay between domestic and geopolitical development interests. The objective of this paper is to explore this complexity in more detail. We argue that the identification of any energy alternative as superior is hardly convincing unless certain standards of inclusive governance are met. We also find that it is important to highlight political-economic differences between energy importers like Morocco and Tunisia and energy exporters like Algeria, Libya, and Egypt. - Research highlights: → North Africa confronted with severe energy supply challenges in near future. → Trade-off between socio-economic development and political power conservation matters. → Economic and geopolitical dimensions of trade-off heterogeneous across North Africa.

    2013-01-01

    The author first recalls the background of nuclear deterrence and the history of the French nuclear arsenal within the Cold War context. He comments the evolution of this arsenal after the US initiatives during the 1980's, and then analyses the situation at the beginning of the 21. century: end of the East-West confrontation, increase of NATO's interventions abroad, war against terrorism by the USA. But the Iranian and North-Korean nuclear programs gave a new momentum to the nuclear. The author discusses the various concepts and approaches of nuclear doctrines and deterrence, and wanders whether France still needs a doctrine relying on nuclear weapons as nuclear weapons are actually present, as the French deterrence doctrine is put in question again, and as some countries seem to be an actual nuclear threat (North Korea, Iran)

  8. A nuclear-powered North Africa: Just a desert mirage or is there something on the horizon?

    2011-01-01

    All of the North African countries have plans to develop nuclear power. If successful, nuclear energy could supply up to 9-15% of all electricity consumption in the region by 2030. How realistic are these plans and under what conditions can they be implemented? This paper seeks to answer this question by analyzing the motivations and capacities for deploying nuclear energy in the five North African countries by examining both regional and national factors. These factors are compared to similar characteristics of the countries with existing nuclear power programs using a series of quantitative indicators. While all five countries have strong motivations to develop nuclear power, which result from the high growth rates in demand for electricity and energy security concerns, their financial and institutional capacities to deploy nuclear energy vary and are generally lower than in those countries which already operate nuclear power plants. Most likely, North Africa will need to rely on external assistance to implement its nuclear energy plans. The article identifies three scenarios of nuclear power development from the interplay between internal and external factors, particularly the success of renewable energy projects and the ability to attract international investment in nuclear power. - Research Highlights: → Nuclear power is an option to diversify electricity and meet demand in N. Africa. → With current plans, nuclear power could generate up to 15% of electricity by 2030. → Capacities in N. Africa are insufficient to launch nuclear power programs. → Deployment of nuclear power in N. Africa depends on external assistance and investment.

  9. Ionospheric hole made by a North Korean rocket launched in 2012 December: Observation with the Russian GNSS

    The Unha-3 rocket was launched due southward at 00:49:46UT on Dec. 12, 2012, from the Tongchang-ri.launch pad on the Yellow Sea side of North Korea. We converted the RINEX format GPS data of the launch day to TEC, and looked for the ionospheric hole signatures. We could not find clear electron depletion signals simply because no GPS satellites were available in the northwestern skies. GPS is the American GNSS system, and other systems are becoming operational. GEONET receivers have been replaced with the new models capable of receiving multiple GNSS, and about 10 percent of them could observe GLONASS and QZSS, the Russian and the Japanese GNSS, respectively, at the time of the Unha-3 launch. More than 20 GLONASS satellites are already in operation, and we used the number 13 satellite to detect the ionospheric hole formation above the Yellow Sea (see Figure). We modified the software to convert RINEX file into TEC time series [Heki et al., JGSJ 2010] in order to handle RINEX v.2.12 files including GLONASS/QZSS data. The broadcast orbits of the GLONASS satellites are given in the geocentric Cartesian coordinates instead of the Keplerian elements like GPS and QZSS. GLONASS uses different microwave frequencies for different satellites, which also required the modification for the original software to calculate TEC. Ozeki & Heki [2010] compared the thrust of the 1998 and 2009 Taepodong missiles by comparing the sizes/depths of the ionospheric holes, and here we compare the hole made by the 2012 December Unha-3 launch with the past cases. The onset times of the depletion are the same, suggesting similar ascending speeds of the three rockets (missiles). Depth of the hole depends both on the amount of water vapor in the exhaust and the background TEC. The hole of the Unha-3 is similar to the 2009 case (or somewhat deeper/larger), which would reflect the vertical TEC in the 2012 case about 1/3 larger than that in 2009. The hole seems to last longer in the 2012 case possibly

    An exceptional number of Middle Eastern and North African nations have recently expressed interest in developing nuclear energy for peaceful purposes. Many of these countries have explored nuclear research in limited ways in the past, but the current focused interest and application of resources towards developing nuclear-generated electricity and nuclear-powered desalination plants is unprecedented. Consequently, questions arise in response to this emerging trend: What instigated this interest? To what end(s) will a nuclear program be applied? Does the country have adequate technical, political, legislative, nonproliferation, and safety infrastructure required for the capability desired? If so, what are the next steps for a country in preparation for a future nuclear program? And if not, what collaboration efforts are possible with the United States or others? This report provides information on the capabilities and interests of 13 countries in the region in nuclear energy programs in light of safety, nonproliferation and security concerns. It also provides information useful for determining potential for offering technical collaboration, financial aid, and/or political support.

    The purpose of this paper is to compare the best practices in North America concerning Preventive Maintenance, Predictive Maintenance and Reliability Centered Maintenance (RCM) or Preventive Maintenance Optimization (PMO) with the time-directed maintenance philosophies utilized by Japanese utilities, and how the Japanese utilities are considering (and some have begun) adopting North American ways of doing business. Preventive Maintenance Living Programs are also discussed, along with the Institute of Nuclear Power Operations AP-913 process, Equipment Reliability Process. Also, a cost benefit analysis will be demonstrated showing how major cost savings can be achieved by shifting from a predominantly time-directed maintenance philosophy to a predominantly predictive strategy utilizing vibration analysis, lubricating oil analysis, thermography and other predictive technologies to better utilize resources, reduce spare part consumption and to minimize maintenance induced errors. As a result of the strides made while incorporating these new philosophies, we no longer advocate tearing apart perfectly good equipment. (author)

    A number of tests were performed in the North area of the SPS in view of investigating crystal-particles interactions for future application in hadron colliders. The rate of nuclear interactions was measured with 400 GeV proton beams directed into a silicon bent crystal. In this way the background induced by the crystal either in amorphous or in channeling orientation was revealed. The results provide fundamental information to put in perspective the use of silicon crystals to assist halo collimation in hadron colliders, whilst minimizing the induced loss.

    This presentation will examine the direct application of nuclear energy solutions in the north, and remote areas of Canada. Further it will challenge the existing energy network based on the shipment of fossil fuels to remote areas, and examine the use of small, modular, and/or deployable nuclear plants in these communities. The use of these small reactors and some newly emerging technologies will likely provide a near total energy supply for these communities. In particular low grade heat processes, district heating, the 'local' production of motive fuels, and local food production will be examined. Additionally the economic and social impact of moving the value added side of many of these processes to the local communities will also be briefly discussed.

    The settlement of nuclear power plants in the North and Northeast Regions Interconnected System, taking into consideration merely economic analysis, is studied. Assuming that the system isn't connected with the Southeast Region, expansion alternatives were defined supported by an optimization model which mathematical formulation was based on a Linear Programming. The main model conditioning was the eletric energy market requirements evolution of the mentioned regions, estimated up to 2010, regarding tendencies presented by forecast elaborated by ELETROBRAS. The system was designed to assure its continuously attendance, even in the case of occurrence of a critical hidrological period, employing as generation sources hidroeletric plants and PWR nuclear power plants of 1245 MWe, similar to ANGRA II.

    1993-01-01

    Results of an empirical survey, one of the first to deal with the Role of the Operator in nuclear power plants in North America, are presented. The survey showed that the theoretical match between operators' responsibility and control (written definition of ''role'') is not supported by the numerical evaluations of these two concepts. Across a dimension from existing to advanced reactors, there is increasingly a shift from hands-on manipulation and readout-by-readout information integration by the operators to a role in which the operator is a passive monitor whose primary task is to give permissives to the automated control system. There is a decreasing degree of control for operators, while responsibility remains high. Decreased control coupled with high responsibility may create shift operating staff problems

    The North African countries Morocco, Algeria, Tunisia, Libya and Egypt have been and are currently experiencing rapid growth in energy demand. This development confronts their political leaders with the question of how to expand or diversify their countries' generation capacities. In this context, renewable energies and nuclear power constitute options that have rarely been exploited so far in the region. This article analyzes the drawbacks and benefits of both alternatives, with a special focus on import and export dynamics. When attempting to make the strategic decision between renewables and atomic power, North African regional specifics and circumstances have to be taken into account. Hence, in a first step, the article characterizes the energy systems of the North African countries and presents scenarios for their future development. In a second step, it scrutinizes the energy challenges these states face in terms of domestic concerns and foreign affairs. Finally, a case study of Algeria is used to demonstrate how renewable energies, but not nuclear power, are able to respond to North African energy challenges. - Research highlights: → Using nuclear power would require fuel imports over the entire operation time. → Hence, energy exporters (Algeria, Libya) would become dependent on fuel imports. → Renewable energies can make North African countries less fuel import dependent. → Nuclear technologies would have to be imported over the whole life cycle of plants. → Domestic production for renewables technologies could be established after a first phase of technology imports.

    We used remote sensing data to detect the changes on surface and ionosphere due to the North Korea nuclear test. To analyze the surface deformation before and after the 6th North Korea (NK) nuclear test, we used Satellite Aperture Radar (SAR) images. It was reported that there were some surface deformation with about 10 cm by the 4th test (Wei, 2017) and the 5th test (Jo, 2017) using Interferometric SAR (InSAR) technique. However we could not obtain surface deformation by the 6th test using InSAR with Advanced Land Observation Satellite 2 (ALOS-2) data because of low coherence in the area close to the epicenter. Although the low coherence can be occurred due to several reasons, the main reason may be large deformation in this particular case. Therefore we applied pixel offset method to measure the amount of surface deformation in the area with low coherence. Pixel offset method calculates the deformation in the directions along track and Line-of-Sight (LOS) using cross correlation of intensity of two SAR images before and after the event for a pixel and is used frequently to obtain large deformation of glacier (e.g. Lee et al., 2015). Applying pixel offset method to the area of the 6th NK nuclear test, we obtained about 3 m surface deformation in maximum. It seems that the larger deformation occurs as the mountain slope is steeper.We then analyzed ionospheric perturbation using Global Navigation Satellite System (GNSS) data. If acoustic wave by a nuclear test goes up to the ionosphere and disturbs electron density, then the changes in slant total electron content (STEC) may be detected by GNSS satellites. STEC perturbation has been reported in the previous NK nuclear tests (e.g. Park et al., 2011). We analyzed the third order derivatives of STEC for 51 GNSS stations in South Korea and found that some perturbation were appeared at 4 stations about 20 40 minutes after the test.

    This paper identifies opportunities for co-operation on regional development and security in the North Pacific region. The Korean Peninsula Energy Development Organization (KEDO) was created in 1993 during bilateral negotiations between the United States and the Democratic People's Republic of Korea (US-DPRK) over North Korea's alleged nuclear weapons program. The negotiations resulted in an agreement to freeze North Korea's known nuclear weapons program in return for the construction of two proliferation-resistant 100 MWe light water reactors (LWR) in North Korea, and the provision of 500,000 tons of heavy fuel oil per year until the completion of the LWR construction as compensation for lost energy production capacity resulting from the shutting down of North Korea's nuclear reactors. The author described the activities of KEDO and examined its internal dynamics. The unique circumstances that produced the Agreed Framework and KEDO in response to a major international crisis of the nuclear program in the DPRK were also highlighted along with the US-DPRK bilateral agreement and the multilateral institution involving the United States, South Korea, Japan and the European Union. Financial support from Australia and Canada was discussed along with the mechanism for engaging North Korea in regularized interaction and technical cooperation. It was concluded that KEDO's record of successes and failures is mixed. The energy security issue has been identified as an area that could result in conflict among Northeast Asian countries which are increasingly dependent on oil supplies from the Middle East. In response, numerous multilateral financing mechanisms have been developed to promote joint business opportunities that exploit natural gas resources in the Russian Far East to address Japanese, Korean and Chinese energy needs. 35 refs

    In 1978, Korea introduced the first nuclear power plant, Kori-1 unit, in parallel with the nation's industrialization policy. Thereafter, Korea has carried out a very ambitious nuclear power program and sustained a strong commitment to nuclear power development. Thus, nuclear is a prime energy source which presently meets about 30 percent of Korea's power demands. Also, Korea won a contract for APR-1400 NPPs to the UAE in 2009 which led to Korea as a significant exporter in the world nuclear market. Recently, the new government of Korea has been launching 'Creative Economy', from this perspective, the quantitative contributions of nuclear sector to the national economic growth are required to be estimated. This paper is to estimate quantitatively the economic values created by nuclear power industry in the framework of national economy. The total economic values created by nuclear power industry are estimated to be 63.6 trillion won for the study period.

    In a study sponsored by the US Nuclear regulatory Commission (NRC), Pacific Northwest Laboratory has developed and applied a methodology for deriving plant-specific risk-based inspection guidance for the auxiliary feedwater (AFW) system at pressurized water reactors that have not undergone probabilistic risk assessment (PRA). This methodology uses existing PRA results and plant operating experience information. Existing PRA-based inspection guidance information recently developed for the NRC for various plants was used to identify generic component failure modes. This information was then combined with plant-specific and industry-wide component information and failure data to identify failure modes and failure mechanisms for the AFW system at the selected plants. North Anna was selected as a plant for study. The product of this effort is a prioritized listing of AFW failures which have occurred at the plant and at other PWRs. This listing is intended for use by the NRC inspectors in preparation of inspection plans addressing AFW risk important components at the North Anna plant

    China, India and USA (nuclear adopted countries) are planning tremendous number of NPPs to meet their increasing electricity demand and Saudi Arabia, Vietnam (nuclear adopting countries) are also planning to include nuclear power in their energy mix as a long-term plan. Korea has exported 4 units of APR1400 to the UAE in December, 2009. Korea became sixth NPP supplier country and our economic feasibility and safety features were started to evaluate worldwide. Nuclear industries became a new driver of Korea’s export and nuclear industries in Korea are now expecting another NPP export to Middle-eastern countries, including UAE and Saudi Arabia, based on the first-mover’s advantage at the UAE. In 2000s, five countries (Japan, USA, France, Russia and Korea), which are able to build NPP, focused on NPP export more than domestic construction. Global trend of world nuclear market changed rapidly, especially after NPP export to the UAE. By the global trend, hegemony of nuclear market migrated from supplier country to buyer country. Nuclear companies started cooperating rather than competing. Financing to developing countries become more important. In general, one of the considerable combinations is Korea-Japan-USA alliance. Korea is in charge of EPC, Japan supports financing and deficient technology (with USA partner), and Japan-USA handles fuel supply and back-end fuel cycle based on new agreed terms of ROK-US Nuclear Cooperation Agreement. This combination was judged to best way to collaborate with global companies. Paying attention to many delayed (or potentially delayed) constructions from Russia, intercepting the construction work will be available in case of contracted countries. Korea can emphasize the short construction time, high responsiveness and mild/equal diplomatic position to the target countries.

    Full text: Full text: Korean Standard Nuclear Plant uses Self Powered Neutron Detectors (SPNDs) to measure the neutron flux in the reactor core. The SPND's height is 40 cm and is located axially at the five different positions and 45 radial places. The design code simulated a reactor core is calculated by segmentation of the core. The segmentation is called as 'node', of which size is normally 20 cm. The axial height of the detector is larger than that of the node, and the larger detector's height maybe product some error on the axially complex shape. The analysis with the detector's signals showed some errors at the non-cosine axial flux shape. In order to reduce the errors for the shape, we tried to divide the detector by introducing the virtual boundary in the detector. Then, each axially 5 detectors had two virtual segmentations respectively and the detector's signal was divided by the inputs. So the more virtual detector's signals were gotten, the more accurate axial shape was produced. The result with virtual segmentations in a detector gave less deviation than the case without virtual segmentation (the current model). After the middle of cycle at the initial core specially, the axial neutron flux shape is changed to the saddle type one. The current model gave some error in Root Mean Square (RMS) between the measured value and the calculated one. The virtual segmentation model gave the better agreement at that time

    Cisplatin is an effective anti-cancer drug; however, one of its side effects is irreversible sensorineural hearing damage. Korean Red Ginseng (KRG) has been used clinically for the treatment of various diseases; however, the underlying mechanism of KRG treatment of ototoxicity has not been studied extensively. The present study aimed to further investigate the mechanism of KRG on cisplatin-induced toxicity in auditory HEI-OC1 cells in vitro, as well as in vivo. The pharmacological effects of KRG on cisplatin-induced changes in the hearing threshold of mice were determined, as well as the effect on the impairment of hair cell arrays. In addition, in order to elucidate the protective mechanisms of KRG, the regulatory effects of KRG on cisplatin-induced apoptosis-associated gene levels and nuclear factor-κB (NF-κB) activation were investigated in auditory cells. The results revealed that KRG prevented cisplatin-induced alterations in the hearing threshold of mice as well as the destruction of hair cell arrays in rat organ of Corti primary explants. In addition, KRG inhibited cisplatin-mediated cell toxicity, reactive oxygen species generation, interleukin-6 production, cytochrome c release and activation of caspases-3 in the HEI-OC1 auditory cell line. Furthermore, the results demonstrated that KRG inhibited the activation of NF-κB and caspase-1. In conclusion, these results provided a model for the pharmacological mechanism of KRG and provided evidence for potential therapies against ototoxicity.

    Safety feature is also needed to more effectively cope with site-wide events affecting multiple units. In this study, the accident mitigation approaches in US are reviewed. The most effective ways to strengthen the defense-in-depth of nuclear power installations are presented as EDMG(Extensive Damage Mitigation Guideline) and FLEX against extreme hazards such as a beyond-design-basis external event (BDBEE) that took place at Fukushima. A combination of the US EDMG and FLEX is applied to develop Korean EDMG, which will be developed to have two different types of EDMGs : 'Site EDMG' to be used for effective technical support to activated TSCs and management of corporate emergency response resources in coordination with the EOF as necessary; and 'Plant-Specific EDMG (for Extreme Event)' to be used by the Technical Support Center (TSC) of a unit where a total loss of control has occurred or plant control cannot be established from the Control Room and Remote Shutdown Panel. The development of Korean EDMG is expected to further enhance mitigation and coping capabilities against site-wide extreme hazard in Korea where a relatively large number of units are assembled on each nuclear power plant site.

    For the decentralization of the North Korea, the decommissioning of the weapon related facilities should be dismantled and the site be decontaminated and restored to the green field. To achieve this final target, Korea should lead the dismantlement projects of the North Korea facilities, sharing work scopes with the member countries of 6 member talks. Many essential technologies for decommissioning of nuclear facilities was acquired and it was concluded that Korean industries could carry out the decommissioning of the North Korea facilities by the some modification or development of the current existing technologies and sharing some tasks for decommissioning of the NK facilities with member countries of 6 member talk

  2. Calculation of risk-based detection limits for radionuclides in the liquid effluents from Korean nuclear power plants

    2017-01-01

    In order to review if present detection limits of radionuclides in liquid effluent from nuclear power plants are effective enough to warrant compliance with regulatory discharge limits, a risk-based approach is developed to derive a new detection limit for each radionuclide based on radiological criteria. Equations and adjustment factors are also proposed to discriminate the validity of the detection limits for multiple radionuclides in the liquid effluent with or without consideration of the nuclide composition. From case studies to three nuclear power plants in Korea with actual operation data from 2006 to 2015, the present detection limits have turned out to be effective for Hanul Unit 1 but may not be sensitive enough for Kori Unit 1 (8 out of 14 radionuclides) and Wolsong Unit 1 (9 out of 42 radionuclides). However, it is shown that the present detection limits for the latter two nuclear power plants can be justified, if credit is given to the radionuclide composition. Otherwise, consideration should be given to adjustment of the present detection limits. The risk-based approach of this study can be used to determine the validity of established detection limits of a specific nuclear power plant. (author)

    The field of nuclear safeguards has received increasing amounts of public attention since the events of the Iraq-UN conflict over Kuwait, the dismantlement of the former Soviet Union, and more recently, the North Korean resistance to nuclear facility inspections by the International Atomic Energy Agency (IAEA). The role of nuclear safeguards in these and other events relating to the world's nuclear material inventory is to assure safekeeping of these materials and to verify the inventory and use of nuclear materials as reported by states that have signed the nuclear Nonproliferation Treaty throughout the world. Nuclear safeguards are measures prescribed by domestic and international regulatory bodies such as DOE, NRC, IAEA, and EURATOM and implemented by the nuclear facility or the regulatory body. These measures include destructive and non destructive analysis of product materials/process by-products for materials control and accountancy purposes, physical protection for domestic safeguards, and containment and surveillance for international safeguards

    The international acceptance of South Korea`s nuclear fuel cycle technology as a peaceful use of nuclear energy needs peaceful relations between South and North Korea. Thus, this study examines the current North Korea`s policy toward South Korea as a part of North Korea`s three-fold survival strategy in the post-cold war period and also forecasts future relations between two countries on the Korean peninsula. To cope with nuclear= nonproliferation policy of the United Sates successfully, which does not allow South Korea`s autonomous nuclear fuel cycle, this study reviews the history of Washington`s nuclear nonproliferation policy with case studies of South Korea`s reprocessing plant project in the 1970`s, US-Japan Nuclear Cooperation Agreement in the 1980`s, and North Korea`s nuclear program in the 1990`s, and for casts the future on nuclear nonproliferation policy of the United States. In conclusion, this analysis tries to develop new approaches to solve two major problems of Korean situation and nuclear nonproliferation policy of the United Sates for the autonomous nuclear fuel cycle in South Korea.

    2008-01-01

    In Korean Nuclear Power Plants (NPPs), two ThermoLuminescent Dosimeters (TLD) were provided to workers who work in an inhomogeneous radiation field; one on the chest and the other on the head. In this way, the effective dose for radiation workers at NPPs was determined by the high deep dose between two radiation dose from these TLDs. This represented a conservative method of evaluating the degree of exposure to radiation. In this study, to prevent the overestimation of the effective dose, field application experiments were implemented using two-dosimeter algorithms developed by several international institutes for the selection of an optimal algorithm. The algorithms used by the Canadian Ontario Power Generation (OPG) and American ANSI HPS N13.41, NCRP (55/50), NCRP (70/30), EPRI (NRC), Lakshmanan, and Kim (Texas A and M University) were extensively analyzed as two-dosimeter algorithms. In particular, three additional TLDs were provided to radiation workers who wore them on the head, chest, and back during maintenance periods, and the measured value were analyzed. The results found no significant differences among the calculated effective doses, apart from Lakshmanan's algorithm. Thus, this paper recommends the NCRP(55/50) algorithm as an optimal two-dosimeter algorithm in consideration of the solid technical background of NCRP and the convenience of radiation works. In addition, it was determined that a two-dosimeter is provided to a single task which is expected to produce a dose rate of more than 1 mSv/hr, a difference of dose rates depending on specific parts of the body of more than 30%, and an exposure dose of more than 2 mSv

    The year 2012 was the 50th anniversary of the Korean Neurosurgical Society, and in 2013, the 15th World Congress of Neurosurgery took place in Seoul, Korea. Thus, it is an appropriate occasion to introduce the world to the history of the Korean Neurosurgical Society and the foundation, development, and growth of Korean neurosurgery. Historical materials and pictures were collected and reviewed from the history book and photo albums of the Korean Neurosurgical Society. During the last 50 years, the Korean Neurosurgical Society and Korean neurosurgery have developed and grown enormously not only in quantity but also in quality. In every aspect, the turning point from the old to the new era of the Korean Neurosurgical Society and Korean neurosurgery was the year 1980. Copyright © 2015. Published by Elsevier Inc.

    Estimated radiation dose is important for assessing and communicating the risks and benefits of pediatric nuclear medicine studies. Radiation dose depends on the radiopharmaceutical, the administered activity, and patient factors such as age and size. Most radiation dose estimates for pediatric nuclear medicine have not been based on administered activities of radiopharmaceuticals recommended by established practice guidelines. The dosage card of the European Association of Nuclear Medicine (EANM) and the North American consensus guidelines each provide recommendations of administered activities of radiopharmaceuticals in children, but there are substantial differences between these two guidelines. For 12 commonly performed pediatric nuclear medicine studies, two established pediatric radiopharmaceutical administration guidelines were used to calculate updated radiation dose estimates and to compare the radiation exposure resulting from the recommendations of each of the guidelines. Estimated radiation doses were calculated for 12 common procedures in pediatric nuclear medicine using administered activities recommended by the dosage card of the EANM (version 1.5.2008) and the 2010 North American consensus guidelines for radiopharmaceutical administered activities in pediatrics. Based on standard models and nominal age-based weights, radiation dose was estimated for typical patients at ages 1, 5, 10 and 15 years and adult. The resulting effective doses were compared, with differences greater than 20% considered significant. Following either the EANM dosage card or the 2010 North American guidelines, the highest effective doses occur with radiopharmaceuticals labeled with fluorine-18 and iodine-123. In 24% of cases, following the North American consensus guidelines would result in a substantially higher radiation dose. The guidelines of the EANM dosage card would lead to a substantially higher radiation dose in 39% of all cases, and in 62% of cases in which patients

    Highlights: • A methodology to identify human error hazards has been established. • The proposed methodology is a preventive approach to identify not only human error causes but also its hazards. • Using the HFACS framework we tried to find out not causations but all of the hazards and relationships among them. • We determined countermeasures against human errors through dealing with latent factors such as organizational influences. - Abstract: A new approach for finding the hazards of human errors, and not just their causes, in the nuclear industry is currently required. This is because finding causes of human errors is really impossible owing to the multiplicity of causes in each case. Thus, this study aims at identifying the relationships among human error hazards and determining the strategies for preventing human error events by means of a reanalysis of the reactor trip events in Korea NPPs. We investigated human errors to find latent factors such as decisions and conditions in all of the unintended reactor trip events during the last dozen years. In this study, we applied the HFACS (Human Factors Analysis and Classification System), which is a commonly utilized tool for investigating human contributions to aviation accidents under a widespread evaluation scheme. Using the HFACS framework, we tried to find out not the causations but all of the hazards and their relationships in terms of organizational factors. Through the trial, we proposed not only meaningful frequencies of each hazards also correlations of them. Also, considering the correlations of each hazards, we suggested useful strategies to prevent human error event. A method to investigate unintended nuclear reactor trips by human errors and the results will be discussed in more detail

    2007-09-11

    An exceptional number of Middle Eastern and North African nations have recently expressed interest in developing nuclear energy for peaceful purposes. Many of these countries have explored nuclear research in limited ways in the past, but the current focused interest and application of resources towards developing nuclear-generated electricity and nuclear-powered desalination plants is unprecedented. Consequently, questions arise in response to this emerging trend: What instigated this interest? To what end(s) will a nuclear program be applied? Does the country have adequate technical, political, legislative, nonproliferation, and safety infrastructure required for the capability desired? If so, what are the next steps for a country in preparation for a future nuclear program? And if not, what collaboration efforts are possible with the United States or others? This report provides information on the capabilities and interests of 13 countries in the region in nuclear energy programs in light of safety, nonproliferation and security concerns. It also provides information useful for determining potential for offering technical collaboration, financial aid, and/or political support.

  13. Pu isotopes in the western North Pacific Ocean before the accident at Fukushima Dai-ichi Nuclear Power Station

    Yamada, M.; Zheng, J.; Aono, T.

    2011-12-01

    Anthropogenic radionuclides such as Pu-239 (half-life: 24100 yr), Pu-240 (half-life: 6560 yr) and Pu-241 (half-life: 14.325 yr) mainly have been released into the environment as the result of atmospheric nuclear weapons testing. In the North Pacific Ocean, two distinct sources of Pu isotopes can be identified; i.e., the global stratospheric fallout and close-in tropospheric fallout from nuclear weapons testing at the Pacific Proving Grounds in the Marshall Islands. The atom ratio of Pu-240/Pu-239 is a powerful fingerprint to identify the sources of Pu in the ocean. The Pu-240/Pu-239 atom ratios in seawater and marine sediment samples collected in the western North Pacific before the accident at Fukushima Dai-ichi Nuclear Power Station will provide useful background data for understanding the process controlling Pu transport and for distinguishing future Pu sources. The atom ratios of Pu-240/Pu-239 in water columns from the Yamato and Tsushima Basins in the Japan Sea were significantly higher than the mean global fallout ratio of 0.18; however, there were no temporal variation of atom ratios during the period from 1984 to 1993 in the Japan Sea. The total Pu-239+240 inventories in the whole water columns were approximately doubled during the period from 1984 to 1993 in the two basins. The atom ratio of Pu-240/Pu-239 in surface water from Sagami Bay, western North Pacific Ocean, was 0.224 and showed no notable variation from the surface to the bottom with the mean atom ratio being 0.234. The atom ratios for the Pacific coast, near the Rokkasho nuclear fuel reprocessing plant, were approximately the same as the 0.224 ratio obtained from Sagami Bay, western North Pacific margin. The atom ratios in the surficial sediments from Sagami Bay ranged from 0.229 to 0.247. The mean atom ratio in the sediment columns in the East China Sea ranged from 0.248 for the Changjiang estuary to 0.268 for the shelf edge. The observed atom ratios were significantly higher than the mean

  14. Integrated framework for the external cost assessment of nuclear power plant accident considering risk aversion: The Korean case

    2016-01-01

    Recently, the estimation of accident costs within the social costs of nuclear power plants (NPPs) has garnered substantial interest. In particular, the risk aversion behavior of the public toward an NPP accident is considered an important factor when integrating risk aversion into NPP accident cost. In this study, an integrated framework for the external cost assessment of NPP accident that measures the value of statistical life (VSL) and the relative risk aversion (RRA) coefficient for NPP accident based on an individual-level survey is proposed. To derive the willingness to pay and the RRA coefficient for NPP accident risks, a survey was conducted on a sample of 1550 individuals in Korea. The estimation obtained a mean VSL of USD 2.78 million and an RRA coefficient of 1.315. Based on the estimation results in which various cost factors were considered, a multiplication factor of 5.16 and an external cost of NPP accidents of 4.39E−03 USD-cents/kW h were estimated. This study is expected to provide insight to energy policy decision-makers on analyzing the economic validity of NPP compared to other energy sources by reflecting the estimated external cost of NPP accident into the unit electricity generation cost of NPP. - Highlights: •External cost assessment framework for NPP is proposed considering risk aversion. •VSL was derived from WTP for mortality risk reduction from hypothetical NPP accident. •RRA was derived to integrate public risk aversion into external cost of NPP accident. •Individual-level survey was conducted to derive WTP and RRA for NPP accident risk. •The external cost was estimated considering the direct cost factors of NPP accident.

    In 1985, the population of the Democratic People's Republic of Korea (North Korea) stood at 20 million, with an annual growth rate of 2.3%. The infant mortality rate was 30/1000 live births and life expectancy was 66 years. The gross national product (GNP) was US$23 billion in 1984, with a per capita GNP of $1175. Both North Korea's labor force and natural resources have been concentrated in recent years on an effort to achieve rapid economic development. During the early 1970s, a large-scale modernization program involving the importation of Western technology, primarily in the heavy industiral sectors of the economy, was attempted and resulted in a massive foreign debt. North Korea has a strongly centralized government under the control of the communist Korean Workers' Party. Literacy in the country is at the 99% level. Medical treatment is free. There is 1 physician/600 population and 1 hospital bed/350 inhabitants.

    For technological reasons, but more importantly political ones, the spread of nuclear weapons is foreseen as inevitable especially with the multiplication of so-called 'threshold states'. On the one hand, technological barriers will gradually disappear with globalization and information sharing in our societies. Furthermore, becoming a threshold power appears today as key to get freedom of action, a tool of counter-deterrence or blackmail according to the camp you belong to, like in the Iranian and north Korean cases. For proliferant countries, it will now consist in an enforcement of an embryonic, even though rather deterrent or even threatening, nuclear program thanks to new technologies, reducing completion times and even allowing to skip the final nuclear test

    This observation implies that the popular view on nuclear weapons amongst Korean public is in part due to lack of knowledge about overall implications of possessing nuclear weapons. In this regard, pros and cons of nuclear weapons development need to be better characterized and understood by the public to support nuclear nonproliferation culture development. Noting lack of literature on characterizing the economics of nuclear weapons development, this study aims at performing economic feasibility analysis of nuclear weapons development in the ROK. For this purpose, an approach called Index technique based on the US experiences was applied to Korean historical data along with cost-benefit analysis and Multi-Criteria Decision Making Analysis. In this study, the scenario of nuclear weapons development against North Korean nuclear threat was compared with conventional weapons-based defense strategy. The comparison was based on cost benefit analysis and qualitative multi-criteria decision analysis. Results indicate that nuclear weapons development is not a desirable option. However, as this work was a rather simplistic academic exercise, further work is needed to support the outcome of the study. Outcome of these investigations would be useful for communication with the public regarding the need for nuclear weapons for national defense and to develop nuclear nonproliferation culture in the ROK

    1999-01-01

    The Republic of Korea started the LAMA full-scope safeguards inspection with the TRIGA research reactor in 1976 when the nuclear industry was at its infancy. Over two decades of rapid economic growth was propelled by stable supply of electricity, substantially from nuclear energy. Today nearly half of the nations electricity comes from sixteen operating nuclear power plants (12 LWRs + 4 OLRs). Total number of facilities under IAEA inspection reaches 30 where the Agency conducts about 400 PDIs annually. Within the last decade, nuclear transparency in Korea has transformed into the international norm primarily from the needs of rapidly expanding domestic nuclear program. In addition, possibility of North/South mutual inspection helped initiate the national inspection regime in addition to the IAEA inspection. The Technology Center for Nuclear Control was established at KAERI in 1994 in order to maintain the nation's nuclear verification expertise in support of the Korean government. National inspections have been carried out simultaneously with the IAEA inspection since 1997 with trial facilities, and all domestic facilities are being inspected from this year. Necessary legal framework and working procedures were developed and field-tried for LWRs, OLRs, fuel fabrication plants and research reactor facilities. Although the inspection equipment and technology along with the safeguards criteria are quite similar to those of the Agency, it is essential to maintain the independent conclusion capabilities between IAEA and the national authority. Substantial improvements in the IAEA safeguards inspection goal attainments since 1997 are credited to the increasing safeguards awareness among operators and SSAC. Further work is necessary to develop the evaluation criteria based on the field inspection results to meet the national inspection goals. The Korean Government signed the Additional Protocol with IAEA on June, 1999 after much deliberation since it involves facilities

  20. Approaches to regional security and arms control in North-East Asia: Tasks ahead

    In order to pave the way towards regional security and arms control in North-East Asia, one of the outstanding issues left over from the cold war, that is, the question of a divided Korea-must be solved first. In settling the Korean problem, the importance of the bilateral negotiation between the parties in direct conflict can never be overemphasized. Over the past few years, fortunately, there has been an accumulation of developments that would have a positive effect on the improvement of inter-Korean relations and peaceful unification of the peninsula. In this sense, the first challenge for the two Koreas is to fulfil the pledges that they committed in the agreements. Concluding agreements is only a first step. They must be implemented fully both in letter and in spirit. Only upon the sincere and complete translation of the agreements into action can the two Koreas establish a solid peace system and move towards unification. This fulfilment will eventually contribute to security and stability in North-East Asia. To emphasize the importance of bilateral negotiation between the two Koreas is not necessarily to exclude the role of external Powers. The four major Powers in North-East Asia-China, Japan, Russia and the United States - could support the South-North dialogue, help ease tensions, facilitate discussion of common security concerns and possibly guarantee the outcomes negotiated between the two Koreas. By fostering bilateral negotiation between the parties to the conflict, they could contribute to enhancing security, confidence and disarmament in the region. At this moment, the most urgent task in the Korean peninsula relates to the problem of Pyongyang's nuclear weapons programme. To solve the nuclear problem, a significant progress on mutual reciprocal inspections must be made immediately in accordance with the wordings of the Declaration. Mutual inspection will test whether Pyongyang intends to go towards nuclear weapons, or away from them and towards

    The consumption of commercial energy in China in 1980 amounted to 603 million tonnes of coal equivalent (tce). By the end of this century, according to preliminary forecasting, it will reach some 1200 million tce at least, but there may still be some gaps in the energy supply. Within the structure of China's current energy supply, coal is the dominating fuel, most of which is burned directly, thus causing serious air pollution particularly in urban areas during the winter season. To take into consideration the environmental impacts in formulating appropriate energy policies and carrying out rational energy planning, a practical regional energy system model in connection with environment impacts has been developed. It is essentially a linear programme model. The model has already been used to evaluate the role of alternative energies and technologies including the nuclear option in North China's future urban energy system. The preliminary results thus obtained have shown that nuclear energy, particularly low-temperature nuclear heat, must be introduced to reduce air pollution and fill the gaps in the energy supply. Since small- or medium-sized heat-only reactors have already been reported to be economical, safe and non-polluting, that will be developed in urban areas in North China to a certain extent by the end of this century.

    For a half century, the nuclear conflict represents a permanent menace for the whole humanity. Through the crisis of Cuba rockets, Israel weapons, Indian explosion, Pakistan equipment, the dismantling of South Africa weapons, the discovery of the clandestine program of Iraq or the North Korean crisis, we understand nuclear threat. 178 countries decided to extend the non proliferation treaty for an indefinite period. But some questions are still to be studied: how it is possible to avoid the clandestine making of nuclear weapons, or if it is possible to convince recalcitrant countries to adhere to a treaty and only when all the questions will find an answer, the nuclear threat will be eliminated.

    Dreicer, J.S.

    1997-01-01

    In a previous study, as part of the Global Nuclear Material Control Model effort, the author estimated the maximum quantity of plutonium that could be produced in thermal research reactors in the potential nuclear weapon states (including North Korea), based on their declared power level. D. Albright has estimated the amount of plutonium the North Koreans may have produced since 1986 in the 5-megawatt-electric power reactor at Yongbon. Albright provided an upper-bound estimate of 53 kilograms of weapon-grade plutonium produced cumulatively if the gas-graphite (magnox) reactor had achieved a load factor of 0.80. This cumulative estimate of 53 kilograms ignores the potential plutonium production in the 8-megawatt-thermal research reactor, IRT-DPRK. To better quantify the cumulative North Korean production, the author conducted a study to estimate the amount of plutonium that could have been produced in the IRT-DPRK research reactor operating at the declared power level during the entire period it has operated, including a period it was not safeguarded. The author estimates that, at most, an additional 6 to 33 kilograms of plutonium could have been produced cumulatively in the research reactor operating at the declared power level during the entire period it has operated, including a 12-year period it was not safeguarded, resulting in a total of 13 to 47 kilograms of plutonium possibly produced in both the research and power reactors

    1998-01-01

    Between the end of the second world war and the collapse of the Berlin wall, the French diplomacy was based on the nuclear policy in a solid and coherent way. This nuclear policy was an 'incarnation' of the national security conception, allowing France to recover its political, military and economical rank on the international scene. The most important characteristic of the French nuclear policy concerns the commercialization of the nuclear energy which aims to ensuring the national security through the building up of a financial, technological and political 'reserve'. In front of the domination of the USA and USSR during the cold war era, NE Asia had a similar geostrategic configuration as Western Europe. It concerns in particular the massive application of nuclear energy for both military and industrial purposes. The bases of the security policy in this region refers to the real use of the nuclear weapon by the USA against Japan in 1945. The French nuclear policy may be considered as a model for the building of the security policy of NE Asia, in particular through the commercialization of the nuclear technology between the countries in concern. This nuclear approach would allow the countries of these region to change their present day national defense policy into an economical and military cooperation. (J.S.)

    Bogazici University and Kandilli Observatory and Earthquake Research Institute (KOERI) is acting as the Turkish National Data Center (NDC) and responsible for the operation of the International Monitoring System (IMS) Primary Seismic Station (PS-43) under Belbasi Nuclear Tests Monitoring Center for the verification of compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT) since February 2000. The NDC is responsible for operating two arrays which are part of the IMS, as well as for transmitting data from these stations to the International Data Centre (IDC) in Vienna. The Belbasi array was established in 1951, as a four-element (Benioff 1051) seismic array as part of the United States Atomic Energy Detection System (USAEDS). Turkish General Staff (TGS) and U.S. Air Force Technical Application Center (AFTAC) under the Defense and Economic Cooperation Agreement (DECA) jointly operated this short period array. The station was upgraded and several seismometers were added to array during 1951 and 1994 and the station code was changed from BSRS (Belbasi Seismic Research Station) to BRTR-PS43 later on. PS-43 is composed of two sub-arrays (Ankara and Keskin): the medium-period array with a ~40 km radius located in Ankara and the short-period array with a ~3 km radius located in Keskin. Each array has a broadband element located at the middle of the circular geometry. Short period instruments are installed at depth 30 meters from the surface while medium and broadband instruments are installed at depth 60 meters from surface. On 25 May 2009, The Democratic People’s Republic of Korea (DPRK) claimed that it had conducted a nuclear test. Corresponding seismic event was recorded by IMS and IDC released first automatic estimation of time (00:54:43 GMT), location (41.2896°N and 129.0480°E) and the magnitude (4.52 mb) of the event in less than two hours time (USGS: 00:54:43 GMT; 41.306°N, 129.029°E; 4.7 mb) During our preliminary analysis of the 25th May 2009 DPRK

    In an uncertain energy international context, the Arab States as of many emergent countries have to face human and economic development critical challenges with limited natural resources. Because of lacks of oil and gas resources, or-for others-demonstrating their will to put more oil on the market, these countries officially stated that they are interested in acquiring nuclear power plants and know-how to ensure a sufficient and quite cheap electricity production. Therefore, although progress as regards renewable energies was carried out, nuclear energy appears to be an interesting alternative in this relative instable energy market framework. To handle successfully their nuclear development project, these States must, however, carry on their current efforts regarding training, industrial co-operation with the major nuclear powers, and collaboration with the specialized international institutions. This cooperation gives to these major actors (the United States, France, Russia and China), a room for implementation of a 'nuclear diplomacy' as means to capture these emerging markets, and so beyond the traditional friendships

Despite focusing on different eras of history, I argue that they rewrite dominant narratives of the Korean War (Cold War logics of anticommunism v. communism and instead focus on North Korean- South Korean friendships/collaborations. Each film also presents similar situations in which a group of disparate “heroes” (made up of unified Koreans band together to circumvent the circumstances of division. This article analyzes historical conditions that influence the emergence of these similarly-themed films as well as film content in order to further think through memorial legacies of the Korean War, as well as to take seriously the radical possibilities of a different future that each film presents.

    Democratic People's Republic of Korea(DPRK) carried out 6th nuclear test on 3 Sep. 2017 at 03:30 UTC. Seismic and infrasound network operated by Korea Meteorological Administration(KMA) successfully detected signals took place in the DPRK's test site, Punggye-ri. First, we checked that Pg/Lg spectral amplitude ratio greater than 1 in the frequency range from 1.0 to 10.0 Hz is useful to discriminate between DPRK test signals and natural earthquakes. KMA's infrasound stations of Cheorwon(CW) and Yanggu(YG) successfully monitored the azimuth direction of the arrival of the infrasound signals generated from DPRK underground nuclear explosions, including the recent test on September 03, 2017. The azimuthal direction of 210(CW) and 130 (YG) point out Punggye-ri test site. Complete waveforms at stations MDJ, CHC2, YNCB in long period(0.05 to 0.1 HZ) are jointly inverted with local P-wave polarities to generate moment tensor inversion result of the explosive moment 1.20e+24 dyne cm(Mw 5.31) and 65% of ISO. The moment magnitude of 5th, 4th and 3rd are 4.61, 4.69 and 4.46 respectively. Source type moment tensor inversion result of DPRK nuclear tests show that the event is significantly away from the deviatoric line of the Hudson et at. (1989) source-type diagram and identifies as having a significant explosive component. Analysis results using seismic and infrasound network verify that the DPRK's explosion tests classified as nuclear test.

    2016-01-01

    This research discusses the design of nuclear research centers to help architects and engineers who will design these centers. Also, the research covers the site characteristics which are used in site selection of nuclear research centers. It covers the principles and standards used in design and planning of nuclear research centers. The master plan of a nuclear research center should be designed based on the system of segregation according to the level of radioactivity. Radiation safety is an important aspect in the design of nuclear research centers. The Egyptian Atomic Energy Authority consists of three nuclear research centers, namely, the Nuclear Research Center in Inshas (Grid Planning Concept), the Hot Laboratories and Waste Management Center in Inshas (Grid Planning Concept) and The National Center for Radiation Research and Technology in Nasr City (Linear Planning Concept). The Radial Planning Concept is the best among all the Planning Concepts as regard radiation safety considerations. Therefore, an architectural design of a new nuclear research center was proposed in a suitable site in North Western Coast of Egypt (Radial Planning Concept) using Auto CAD and 3ds Max programs. This site is suitable and satisfies many of the site requirements. It is recommended that the architectural design of nuclear research centers should be supervised by an architectural engineer experienced in architectural design of nuclear facilities

  9. Security environment and nuclear proliferation problems in East Asia

    Suh, Mark Byung-Moon

    1997-01-01

    East Asia was and still is divided into two conflicting ideological blocs. Because of the Cold War between these two blocs, two international wars were fought and tensions limited interactions among these countries. Despite these political constraints, in recent years East Asia has become economically one of the most dynamic regions in the world. Now that the Cold War between the USA and the Soviet Union is over, the danger of global nuclear war involving the nuclear powers in the region has been practically eliminated. Nonetheless, security has become more complex and demands a whole new set of arrangements. Yet the region lacks a cohesive multilateral framework for conflict resolution, and only recently have various attempts been made to create a political forum for the countries in the region. The problem and the danger of nuclear proliferation was vividly shown by the North Korean nuclear crisis in the last years. This issue not only halted the fragile process of normalization between the two Koreas, which started in 1988, but almost led to a new military conflict on the peninsula involving the two Koreas and the USA. It was defused only after the USA proved willing to offer security guarantees to North Korea. This problem still needs to be resolved, and it demands radical changes in the overall political environment in the region. Needless to say, proliferation in North Korea would have entailed grave consequences for the security of the region as well as for the international non-proliferation regime. This paper reviews the issue of nuclear proliferation of the three non-nuclear states in the region and deals with the non-introduction of nuclear weapons in the region by the nuclear powers. It discusses the prospects for a nuclear-weapon-free zone on the Korean peninsula. Perspectives of a sustainable security environment in East Asia will be briefly discussed

    2013-01-01

    The impact of the Fukushima nuclear accident in north–western Greece was assessed through an environmental monitoring programme activated by the Nuclear Physics Laboratory of the University of Ioannina. Measurements of 131 I were carried out in atmospheric particulate, ovine milk and grass samples. In daily aerosol samplings, radioiodine was first detected on March 25-26, 2011 and reached maximum levels, up to 294 μBq m -3 , between April 2 and April 4, 2011. In ovine milk samples, 131 I concentrations ranged from 2.0 to 2.7 Bq L -1 between April 2 and April 6, 2011, while an average activity of 2.7 Bq kg -1 was measured in grass samples on April 4, 2011. The 134,137 Cs isotopes were below detection limits in all samples and could only be determined in the air, by analysis of multiple daily filters. A maximum average activity concentration of 137 Cs amounting to 24 μBq m -3 was measured during the period from April 5 to April 9, 2011, with the 134 Cs/ 137 Cs activity ratio being close to unity. Activity concentrations were consistent with measurements conducted in other parts of the country and were well below those reported in May 1986 after the Chernobyl accident. The committed effective dose to the whole body and to the thyroid gland from inhalation of 131 I was estimated for the adult and infant population and was found to be of no concern for the public health.

    1999-01-01

    In order to meet national needs for increasing electric power generation in the Republic of Korea in the 2000s, the Korean nuclear development group (KNDG) is developing a standardized evolutionary advanced light water reactor (ALWR), the Korean Next Generation Reactor (KNGR). It is an advanced version of the successful Korean Standard Nuclear Power Plant (KSNP) design, which meets utility needs for safety enhancement, performance improvement and ease of operation and maintenance. The KNGR design starts fro the proven design concept of the currently operating KSNPs with uprated power and advanced design features required by the utility. The KNGR design is currently in the final stage of the basic design, and the paper describes the major nuclear steam supply system (NSSS) design features of the KNGR together with introduction of the KNGR development program.

    As a method of designing and evaluating arms control measures, this study takes a combined approach of qualitative analysis and military simulation. Three qualitative criteria derived from the case studies on the Korean and European arms control are used to examine whether these measures are legally binding, verifiable, and negotiable. One quantifiable criterion is used to test against the base case scenario (a one-day surprise attach by North Korea) whether arms control measures will stabilize or destabilize the military status quo on the Peninsula in terms of North Korea's extent of penetration in the actual war situations. Four alternative measures are derived from the analysis: (1) Confidence and Security Building Measures (CSBMs); (2) Establishment of Asymmetric Non-Deployment Zone (NDZ); (3) Reduction of the joint US-South Korean 'Team Spirit' exercises and North Korea's Forward Deployed Forces; and, (4) Reduction of South Korean and US forces and North Korean Forces. Findings indicate that establishment of the NDZ and a North Korean unilateral reduction are estimated to best achieve the goal of South Korean arms control

    2013-01-01

    Andreeva Bay is located near Murmansk in the Russian Federation close to the Norwegian border. The ex-naval site was used to de-fuel nuclear-powered submarines and icebreakers during the Cold War. Approximately 22,000 fuel assemblies remain in three Dry Storage Units (DSUs) which means that Andreeva Bay has one of the largest stockpiles of highly enriched spent nuclear fuel (SNF) in the world. The high contamination and deteriorating condition of the SNF canisters has made improvements to the management of the SNF a high priority for the international community for safety, security and environmental reasons. International Donors have, since 2002, provided support to projects at Andreeva concerned with improving the management of the SNF. This long-term programme of work has been coordinated between the International Donors and responsible bodies within the Russian Federation. Options for the safe and secure management of SNF at Andreeva Bay were considered in 2004 and developed by a number of Russian Institutes with international participation. This consisted of site investigations, surveys and studies to understand the technical challenges. A principal agreement was reached that the SNF would be removed from the site altogether and transported to Russia's reprocessing facility at Mayak in the Urals. The analytical studies provided the information necessary to develop the construction plan for the site. Following design and regulatory processes, stakeholders endorsed the technical solution in April 2007. This detailed the processes, facilities and equipment required to safely remove the SNF and identified other site services and support facilities required on the site. Implementation of this strategy is now well underway with the facilities in various states of construction. Physical works have been performed to address the most urgent tasks including weather protection over one of the DSUs, installation of shielding over the cells, provision of radiation

    2018-03-01

    A method is outlined and tested to detect low level nuclear or chemical sources from time series of concentration measurements. The method uses a mesoscale atmospheric model to simulate the concentration signature from a known or suspected source at a receptor which is then regressed successively against segments of the measurement series to create time series of metrics that measure the goodness of fit between the signatures and the measurement segments. The method was applied to radioxenon data from the Comprehensive Test Ban Treaty (CTBT) collection site in Ussuriysk, Russia (RN58) after the Democratic People's Republic of Korea (North Korea) underground nuclear test on February 12, 2013 near Punggye. The metrics were found to be a good screening tool to locate data segments with a strong likelihood of origin from Punggye, especially when multiplied together to a determine the joint probability. Metrics from RN58 were also used to find the probability that activity measured in February and April of 2013 originated from the Feb 12 test. A detailed analysis of an RN58 data segment from April 3/4, 2013 was also carried out for a grid of source locations around Punggye and identified Punggye as the most likely point of origin. Thus, the results support the strong possibility that radioxenon was emitted from the test site at various times in April and was detected intermittently at RN58, depending on the wind direction. The method does not locate unsuspected sources, but instead, evaluates the probability of a source at a specified location. However, it can be extended to include a set of suspected sources. Extension of the method to higher resolution data sets, arbitrary sampling, and time-varying sources is discussed along with a path to evaluate uncertainty in the calculated probabilities.

  18. The impact of the multilateral approach to the nuclear fuel cycle in Malaysia's nuclear fuel cycle policy

    International Nuclear Information System (INIS)

    Baharuddin, B.; Ferdinand, P.

    2014-01-01

    Since the Pakistan-India nuclear weapon race, the North Korean nuclear test and the September 11 attack revealed Abdul Qadeer Khan's clandestine nuclear black market and the fear that Iran's nuclear program may be used for nuclear weapon development, scrutiny of activities related to nuclear technologies, especially technology transfer has become more stringent. The nuclear supplier group has initiated a multilateral nuclear fuel cycle regime with the purpose of guaranteeing nuclear fuel supply and at the same time preventing the spread of nuclear proliferation. Malaysia wants to develop a programme for the peaceful use of nuclear energy and it needs to accommodate itself to this policy. When considering developing a nuclear fuel cycle policy, the key elements that Malaysia needs to consider are the extent of the fuel cycle technologies that it intends to acquire and the costs (financial and political) of acquiring them. Therefore, this paper will examine how the multilateral approach to the nuclear fuel cycle may influence Malaysia's nuclear fuel cycle policy, without jeopardising the country's rights and sovereignty as stipulated under the NPT.

    The author considers the impact of leader Kim Jong Il's death on 6-party talks surrounding the nuclear issue. Firstly, the history of these 6-party talks has to be reexamined to ensure an accurate understanding of their 'objectives and limitations' because the author believes that there are 3 'unpleasant truths' behind these talks, held 6 times since the summer of 2003, that no one wants to talk about. 1. North Korea has no interest in abandoning nuclear weapons; 2. Japan, the U.S., China, and South Korea do not want war; 3. The nuclear issue will not be resolved by 6-party talks. In fact, there is little potential that 6-party talks which aim to resolve the North Korean nuclear issue will move towards a new substantive agreement

    Full Text Available This article covers the changes that have taken place in inter-Korean relations since the fall of the Soviet regimes. In the first few years following the fall of the iron curtain, the Korean perimeter became a scenario of confrontation that seemed to perpetuate theproblem. However, in the second half of the ‘90s, north-east Asia began to undergo a real change that resulted in public contacts between the two Koreas. The new game that was officially opened by the “Sunshine policy” led to a deep-seated rethinking of foreignpolicy by both states, and opened a new chapter in inter-Korean relations that has clearly demonstrated the important dimension and repercussions of the conflict in the geo-strategic framework of the entire East Asian area, as well as in international politics.

    Renewable energy (RE) is the best sustainable energy solution South Korea can provide to assist North Korea in overcoming its chronic energy shortage. Designed as a follow-on research to Sin et al., a survey was conducted with a panel of experts consisting of various disciplines and affiliations using the analytic hierarchy process (AHP) with benefit, opportunity, cost, and risk (BOCR). The results showed the panel viewed security as the most important factor among the strategic criteria. For the level 1 attributes, the panel showed no significant differences of opinion among the different alternatives; however, cost showed to be the most important factor for the panel. The panel chose wind power as the best alternative source of energy for North Korea; however, there were some differences in opinion among the sub-groups of the panel depending on the composition and the expertise of the sub-group. Compared to other studies on the similar topic, this research stands out in that the research results were derived using AHP and BOCR and that the panel was composed of both Korean and foreign experts on North Korea affiliated with state-run research organizations, armed forces, non-governmental organizations, academic research organizations, private consulting firms, and journalism. The research arrived at the conclusion that the following factors must be considered as South Korea designs its future North Korean energy assistance policy: (1) RE assistance for North Korea can take on various forms; hence, experts consulted during the design, writing, and implementation phases of the policy in question must possess knowledge and expertise in the appropriate technology and methodology being considered; (2) possibility of a sudden destabilization of the Northeast Asian security paradigm due to the collapse of North Korea; and (3) continued nuclearization of North Korea.

    In the post-Cold War era, the threats of horizontal nuclear proliferation emerge as the forefront security issue while the nuclear arms races among existing nuclear weapon states reduce to a remarkable extent. In this context, there arises lots of research attention to the IAEA nuclear safeguards which have been viewed as the core of international monitoring on the clandestine nuclear activities of potential proliferators. However, previous attention tended to highlight the political aspects of the IAEA nuclear safeguards, centering on the possibilities and limitations of the IAEA's inspection authority. In contrast, this paper purports to focus on the technical aspects of the IAEA nuclear safeguards, so it can show the intrinsic problems of those safeguards in stemming the proliferation of nuclear weapons. This paper mainly deals with the technical objectives and options of the IAEA nuclear safeguards, the technical indices of clandestine nuclear activities, and some measures to improve the efficacy of the IAEA nuclear safeguards. Hopefully, this paper is expected to lead us to approach the issue of the North Korean nuclear transparency from the technical perspective as well as the political one

  12. Inter-Korean Forest Cooperation 1998–2012: A Policy Arrangement Approach

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Despite political obstacles, South and North Korea have a history of conducting cooperative forest activities. Since 1999, the two Koreas have taken part in implementing cooperative forest projects, including reforestation, construction of tree nurseries, and control of insect pests, to achieve sustainability of the forests on the Korean Peninsula. This paper analyzes South Korean policies for inter-Korean forest cooperation, using a policy arrangement approach (PAA with four dimensions: discourse, actors, rules of the game, and power. Policy changes by three South Korean administrations are analyzed: that of Kim Dae Jung (1998–2002, Roh Moo Hyun (2003–2007 and Lee Myoung Bak (2008–2012. The analysis focuses on an examination of the interactions among the four dimensions of policy arrangement and the policies of the administrations. This research indicates that change of the South Korean policy discourse to North Korea by the various administrations has fundamentally influenced actors and their resources, as well as the rules, in the field of inter-Korean forest cooperation. Insights from this analysis can contribute to the design of bilateral forest cooperation policies on the Korean Peninsula.

    The purpose of the present study was to examine the validity and reliability of the Korean version of the Eating Disorder Inventory-2 (EDI-2) in Korean patients with eating disorders and healthy controls, and to investigate cultural differences of EDI-2 between a Korean group and a North American standardization sample. The Korean version of the EDI-2 was prepared after comprehensive clinical assessment of Korean patients with eating disorders (n=327) as well as female undergraduates (n=176). Results were compared between eating disorder subgroups (anorexia nervosa, bulimia nervosa and eating disorders not otherwise specified) and those of a North American standardization sample and healthy controls. The results showed that the Korean EDI-2 had adequate internal consistency (0.77-0.93) and discriminated well between patients with eating disorders and healthy controls on all subscales. Significant differences in EDI-2 subscale scores between the eating disorder groups and the healthy control group were observed; however, there was no discernible difference among the eating disorder subgroups. When compared with a North American standardization sample, the Korean control group showed significantly higher scores for drive for thinness and asceticism. When patient groups were compared, the Korean group showed significantly lower scores for perfectionism. As expected, the results accurately reflected psychometric properties of the Korean version of EDI-2 for eating disorder patients in Korea. These findings also suggest that common characteristics for the eating disorder exist as a whole rather than with significant difference between each subgroup. In addition, significant differences between the Korean and the North American groups for both patients and controls also demonstrated specific cultural differences.

    2017-03-01

    The present study examines a climate regime shift in the time series of the number of rainy days during August in the Korean Peninsula. The statistical change-point analysis indicates that a significant shift occurred in the time series around 1998, providing a rationale to divide it into two parts: 1975-1997 for the shorter rainy-day period and 1998-2012 for the longer rainy-day period. To examine the cause of recent rapid increases in the number of days with precipitation in August in the Korean Peninsula, differences in the averages of large-scale environments between the 1998-2012 period and the 1975-1997 period were analyzed. The differences in stream flows showed that anomalous cyclones were reinforced in the East Asian continent while anomalous anticyclones were reinforced in the western North Pacific at all layers of the troposphere. The anomalous anticyclones reinforced in the western North Pacific were associated with the western North Pacific subtropical high (WNPSH) developed a little more toward the Korean Peninsula recently. Consequently, the Korean Peninsula has been affected by anomalous south westerlies that supplied warm and humid airs from low tropical regions to the Korean Peninsula. The vertical thermal instability (warm anomaly at lower-level and cold anomaly at middle and upper-level) developed near the Korean Peninsula. In addition, upper tropospheric jets were reinforced further recently near the Korean Peninsula to provide good environments for development of upward flows. The frequency of TCs that affect the Korean Peninsula in August also increased rapidly since 1998.

    Human errors can occur during the test and maintenance of steam generator, safety injection system and other various systems and devices in nuclear power plants (NPPs). Most of human errors can be improved by the human error prevention techniques such as self-check, peer-check, concurrent verification and etc. Another important technique is to share work information among main control room (MCR) operators and field workers. Various field service automation tools have been developed with recent information technology in many countries. APR1400 computerized procedure system (CPS) has been developed for the MCR operators of Shin-Kori 3 and 4 units. Especially, the concurrent verification support design is applied in the construction project of Shin-Hanul 1 and 2 CPS. It is expected that the proposed mobile CPS can enhance the reduction of human errors by supporting human error prevention techniques and information sharing. This paper describes the technical issues of the mobile CPS (mobile CPS) in the initial development stage. Based on the design of APR1400, CRI CPS has been developed and operated for SKN 3 and 4 HFE V and V and license test for the MCR operating staff. Therefore the mobile CPS will be developed by upgrading the CRI CPS with improved features

    Impingement of a large amount of gelatinous plankton, Salpa fusiformis on the seawater intake system-screens in a nuclear power plant at Uljin was firstly recorded on 18th June 2003. Whole amount of the clogged animals was estimated were presumptively at 295 tons and the shortage of cooling seawater supply by the animal clogging caused 38% of decrease in generation capability of the power plant. Zooplankton collection with a multiple towing net during the day and at night from 5 to 6 June 2003 included various gelatinous zooplanktons known to be warm water species such as salps and siphonophores. Comparatively larger species, Salpa fusiformis occupied 25.4% in individual density among the gelatinous plankton and showed surface distribution in the depth shallower than thermocline, performing little diel vertical migration. Temperature, salinity and satellite data also showed warm surface current predominated over the southern coastal region near the power plant in June. The results suggested that warm surface current occasionally extended into the neritic region may transfer S. fusiformis, to the waters off the power plant. The environmental factors and their relation to ecobiology of the large quantity of salpa population that are being sucked into the intake channel of the power plant are discussed.

    The loss of steam due to valve leakage leads to the inefficiency of power generation at the nuclear power plants. Under the normal conditions of plant operation, it is difficult to detect valve leaks early enough to prevent consequential damages and losses. The capability of timely detection allows the plant adequate time to prepare repair plans, which would ultimately result in efficient power production. Therefore, timing of detection is one of the most important factors in dealing with valve leakage problems. The VLMS has been developed to meet such an industrial demand. It provides early detection of valve leakage by real-time monitoring through the acoustic sensors installed on the inlet and the outlet of the valve. The KSNP+ utilizes the VLMS to enhance the performance and maintenance of major valves at plants. The VLMS will enable the plant to detect the leakage of valve at an early stage. It can reduce the steam losses and save related valve maintenance cost by performing fast diagnosis of valve leakage. (authors)

    Fires in NPPs are unfortunately not avoidable and to consider during the planning and operation period of the plants. The multitude of combustible materials which are used especially cables, oils and other building materials describe a potential source of danger. In Germany recently a new planning guideline for the fire protection field in NPPs has been adopted: the nuclear guideline KTA 1401. This document certainly is one of the most progressive guidelines for the fire protection field and has united · structural engineering elements of fire protection · electrotechnical and machine components · as well as questions of fire alarm and organisation measures. Passive and active fire protection measures are explained and layed down in their complexity within this document. Our group of companies has realised quit a lot of fire protection projects in Europe during the last years, especially within retrofitting measures for NPPs in Germany, Switzerland, Russia, the Ukraine and Lithuania, the Czech and Slovak Republic as well as within decommissioning projects of NPPs. We have carried out international fire protection projects of the EBRD, London, and within the framework of TACIS projects of the European Commission, i. a. linked with the working out of fire protection analyses for NPPs realised in close co-operation with the Germanischer Lloyd, Hamburg. We especially have wide experiences in improving the fire protection of cable installations where a 100% separation of the different safety systems is not any longer possible

  8. Improved management of SG BD demineralizer for reduced generation of low-level radioactive spent resin in Korean nuclear power plants

    Rhee, I.; Cho, D.; Yeon, J.

    2003-01-01

    Most nuclear power plants in Korea have adopted Ethanolamine(ETA) as a secondary pH control agent to increase the pH at the liquid phase, which may reduce the corrosion in steam generator tubes and moisture separator/reheat system. Along with its beneficial effect of SG protection from corrosion and degradation, the replacement of ammonia with ETA causes the increased generation of spent resin and the reduced run time of demineralizer in steam generator blowdown(SG BD) system. The composition ratio of cation- to anion- exchange resin in SG BD mixed bed should be increased in the ETA chemistry environment to meet the ratio of cation to anion in the aqueous solution, which results in the simultaneous exhaustion of cation and anion exchange resins. The utilization rate of mixed bed is greatest at the cation-to-anion ratio of 95:1 on the theoretical equivalent basis in the solution, but practically highest at that of 22:1 due to the possible inhomogeneous distribution of cation and anion exchange resins in SG BD bed. The run time of the bed could be extended by 30% such that, at that much, the purchase cost of new resin is saved and the production rate of spent resin is reduced. The guideline on the replacement of resin in SG BD bed is not necessary to secure the removal of radioactive particles without the leakage of the primary coolant into the secondary side since all the radioactive ions can be eliminated by SG BD bed with the sufficient time. They are retained during more than one month after their ingress into the SG BD bed without leakage. With the reduced replacement, thus, the SG BD spent resin that comprises 65% of low-level radioactive solid waste can be much cut down

    Before addressing the issue of public and utility acceptance of nuclear power in Korea, let me briefly explain the Korean nuclear power program and development plan for a passively safe nuclear power plant in Korea. At present, there are eight PWRs and one CANDU in operation; two PWRs are under construction, and contract negotiations are underway for one more CANDU and two more PWRs, which are scheduled to be completed by 1997,1998 and 1999, respectively. According to a recent forecast for electricity demand in Korea, about fifty additional nuclear power plants with a generating capacity of 1000MWe are required by the year 2030. Until around 2006, Korean standardized nuclear power plants with evolutionary features such as those in the ALWR program are to be built, and a new type of nuclear power plant with passive safety features is expected to be constructed after 2006. The Korean government is making a serious effort to increase public understanding of the safety of nuclear power plants and radioactive waste storage and disposal. In addition, the Korean government has recently introduced a program of benefits for residents near nuclear power plants. By this program, common facilities such as community centers and new roads are constructed, and scholarships are given to the local students. Nuclear power is accepted positively by the utility and reasonably well by the public in Korea

    Full Text Available Understanding the genetics of a population is a critical component of developing conservation strategies. We used archived tissue samples from golden eagles (Aquila chrysaetos canadensis in three geographic regions of western North America to conduct a preliminary study of the genetics of the North American subspecies, and to provide data for United States Fish and Wildlife Service (USFWS decision-making for golden eagle management. We used a combination of mitochondrial DNA (mtDNA D-loop sequences and 16 nuclear DNA (nDNA microsatellite loci to investigate the extent of gene flow among our sampling areas in Idaho, California and Alaska and to determine if we could distinguish birds from the different geographic regions based on their genetic profiles. Our results indicate high genetic diversity, low genetic structure and high connectivity. Nuclear DNA Fst values between Idaho and California were low but significantly different from zero (0.026. Bayesian clustering methods indicated a single population, and we were unable to distinguish summer breeding residents from different regions. Results of the mtDNA AMOVA showed that most of the haplotype variation (97% was within the geographic populations while 3% variation was partitioned among them. One haplotype was common to all three areas. One region-specific haplotype was detected in California and one in Idaho, but additional sampling is required to determine if these haplotypes are unique to those geographic areas or a sampling artifact. We discuss potential sources of the high gene flow for this species including natal and breeding dispersal, floaters, and changes in migratory behavior as a result of environmental factors such as climate change and habitat alteration. Our preliminary findings can help inform the USFWS in development of golden eagle management strategies and provide a basis for additional research into the complex dynamics of the North American subspecies.

    Understanding the genetics of a population is a critical component of developing conservation strategies. We used archived tissue samples from golden eagles (Aquila chrysaetos canadensis) in three geographic regions of western North America to conduct a preliminary study of the genetics of the North American subspecies, and to provide data for United States Fish and Wildlife Service (USFWS) decision-making for golden eagle management. We used a combination of mitochondrial DNA (mtDNA) D-loop sequences and 16 nuclear DNA (nDNA) microsatellite loci to investigate the extent of gene flow among our sampling areas in Idaho, California and Alaska and to determine if we could distinguish birds from the different geographic regions based on their genetic profiles. Our results indicate high genetic diversity, low genetic structure and high connectivity. Nuclear DNA Fst values between Idaho and California were low but significantly different from zero (0.026). Bayesian clustering methods indicated a single population, and we were unable to distinguish summer breeding residents from different regions. Results of the mtDNA AMOVA showed that most of the haplotype variation (97%) was within the geographic populations while 3% variation was partitioned among them. One haplotype was common to all three areas. One region-specific haplotype was detected in California and one in Idaho, but additional sampling is required to determine if these haplotypes are unique to those geographic areas or a sampling artifact. We discuss potential sources of the high gene flow for this species including natal and breeding dispersal, floaters, and changes in migratory behavior as a result of environmental factors such as climate change and habitat alteration. Our preliminary findings can help inform the USFWS in development of golden eagle management strategies and provide a basis for additional research into the complex dynamics of the North American subspecies.

    The Korean Peninsula is one of the world`s most tense military confrontational sites. Nearly 2 million North Korean, South Korean, and U.S. troops face each other along the 255-km long military demarcation line. Confidence building measures (CBMs), particularly military ones, that address the security needs of both countries could decrease the danger of conflict and help create an environment where a peace regime might be negotiated. In spite of the present high level of mutual distrust, steps can still be taken to prepare for future development and implementation of CBMs. This paper defines some simple and specific first steps toward CBMs that might be useful on the Korean Peninsula.

    The objective of this project is to analyze a nuclear performance of the Korean HCML(Helium Cooled Molten Lithium) TBM(Test Blanket Module) which will be installed in ITER(International Thermonuclear Experimental Reactor). This project is intended to analyze a neutronic design and nuclear performances of the Korean HCML ITER TBM through the transport calculation of MCCARD. In detail, we will conduct numerical experiments for analyzing the neutronic design of the Korean HCML TBM and the DEMO fusion blanket, and improving the nuclear performances. The results of the numerical experiments performed in this project will be utilized further for a design optimization of the Korean HCML TBM. In this project, Monte Carlo transport calculations for evaluating TBR (Tritium Breeding Ratio) and EMF (Energy Multiplication factor) were conducted to analyze a nuclear performance of the Korean HCML TBM. The activation characteristics and shielding performances for the Korean HCML TBM were analyzed using ORIGEN and MCCARD. We proposed the neutronic methodologies for analyzing the nuclear characteristics of the fusion blanket, which was applied to the blanket analysis of a DEMO fusion reactor. In the results, the TBR of the Korean HCML ITER TBM is 0.1352 and the EMF is 1.362. Taking into account a limitation for the Li amount in ITER TBM, it is expected that tritium self-sufficiency condition can be satisfied through a change of the Li quantity and enrichment. In the results of activation and shielding analysis, the activity drops to 1.5% of the initial value and the decay heat drops to 0.02% of the initial amount after 10 years from plasma shutdown.

    This chapter elaborates on the major factors contributing to the development of the South Korean nuclear energy program during the last three decades. The history of Korean nuclear development followed three phases: (1) early nuclear developments (1954-1961); (2) the beginning of a nuclear power program (1962-1971); and (3) the development of a nuclear power program (1972-1981). Factors which could interrupt nuclear development are the risk of proliferation, national security, and reversals in the nuclear programs of Japan, France, and West Germany. 66 references, 1 figure, 3 tables

    The author illustrates how the evolution of technologies of information and communication (TICs), notably because of the ease and rate of information exchange, has also effects on studies on nuclear proliferation information and their validity. He first describes the case of information about North-Korean missile launchers: information released about the modification of Chinese trucks, use of images published on YouTube and exploitation of Google Earth to actually prove that this information was true. Secondly, he comments the case of the Matiran Iranian complex (an underground nuclear site): questions related to the validity of some photos issued by an Iranian dissident group, use of meta data to check it, use of GPS records to reconstruct the way followed by a European who visited the site. The third case concerns the claim of the launching of ballistic missiles from a submarine by North Korea in January 2016: release of a North Korean video, identification of the location, and frame-by-frame analysis of the video which revealed that the missile actually exploded

    An aerial radiological survey was conducted over the Perry Nuclear Power Plant, North Perry, Ohio. The purpose of the 234-square-kilometer (91-square-mile) survey was to document the terrestrial gamma environment of the plant and surrounding area. An exposure rate contour map at 1 meter above ground level was constructed from the gamma data and overlaid on an aerial photograph and map of the area. Exposure rates increased from 0 microroentgens per hour (μR/h) over Lake Erie to 9 μR/h as the distance from Lake Erie increased. Only one anomalous area appears on the map, which is due to an excess of Bi-214 in a landfill area. Ground-based exposure rate measurements and soil samples were obtained to support the aerial data. Oblique aerial photographs of the plant were also acquired during the survey. 6 refs., 6 figs., 1 tab

    It is necessary for the Korean government and the atomic energy industry to grasp the current image of the Korean people on nuclear energy and to consider policy measures for enhancing the acceptance of nuclear energy over other agenda. In order to improve image of the nuclear energy and the contents analyzed in the previous section, we provide the following suggestions on the policy formulation of the government and the nuclear energy industry. The first is the expansion of related technology research to expand the safety of non-power generation and radioactive waste management in nuclear power generation. The second is building a new PR strategy for the nuclear power generation process and operation. This means that the nuclear industry needs to focus more on detailed information from the basic theory of nuclear power generation to the whole development process. It is necessary to establish a marketing strategy so that the site can be easily retrieved from internet portals such as Naver, Daum, and Google, portals most widely used by Internet users. Disaster response to nuclear power plant accident should be taught to the public by the government and the industry. After the screening of the Pandora movie, the Korean people became more interested in how to cope with serious accidents at nuclear power plants. Therefore, the government and the nuclear industry need to be more active in spreading to the public on the existing public evacuation tips.

    Full Text Available Surface seawater 134Cs and 137Cs samples were collected in the central and western North Pacific Ocean during the 2 yr after the Fukushima Dai-ichi Nuclear Power Plant accident to monitor dispersion patterns of these radioisotopes towards the Hawaiian Islands. In the absence of other recent sources and due to its short half-life, only those parts of the Pacific Ocean would have detectable 134Cs values that were impacted by Fukushima releases. Between March and May 2011, 134Cs was not detected around the Hawaiian Islands and Guam. Here, most 137Cs activities (1.2–1.5 Bq m–3 were in the range of expected preexisting levels. Some samples north of the Hawaiian Islands (1.6–1.8 Bq m–3 were elevated above the 23-month baseline established in surface seawater in Hawaii indicating that those might carry atmospheric fallout. The 23-month time-series analysis of surface seawater from Hawaii did not reveal any seasonal variability or trends, with an average activity of 1.46 ± 0.06 Bq m–3 (Station Aloha, 18 values. In contrast, samples collected between Japan and Hawaii contained 134Cs activities in the range of 1–4 Bq m–3, and 137Cs levels were about 2–3 times above the preexisting activities. We found that the southern boundary of the Kuroshio and Kuroshio extension currents represented a boundary for radiation dispersion with higher activities detected within and north of the major currents. The radiation plume has not been detected over the past 2 yr at the main Hawaiian Islands due to the transport patterns across the Kuroshio and Kuroshio extension currents.

    An aerial radiological survey was performed from 13 to 24 April 1981 over a 235 square kilometer area centered on the William B. McGuire Nuclear Station at Cowans Ford Dam, North Carolina. All gamma-photon data were collected by flying North-South lines spaced 228 meters apart at an altitude of 122 meters above ground level. Processed data showed that all gamma-photons detected within the survey area were those expected from naturally occurring terrestrial background emitters. Count rates obtained from the aerial platform were converted to exposure rates at 1 meter above the ground and are presented in the form of an isoradiation contour map. The observed exposure rates were between 5 and 22 microroentgens per hour (μR/h), with most of the area ranging from 5 to 9 μR/h. These values include an estimated cosmic ray contribution of 4.0 μR/h. The exposure rate obtained from soil samples taken from within the survey site displayed positive agreement with the aerial data

    The characteristics of disease in North Korea, including severe malnutrition and infectious disease risks, have not been openly and widely analyzed. This study was performed to estimate the risks of infectious diseases among refugees from North Korea. A literature review of clinical studies among North Korean defectors was conducted to statistically estimate the risks of infectious diseases among North Korean subjects. A total of six groups of data from five publications covering the years 2004 to 2014 were identified. Tuberculosis and viral hepatitis appeared to be the two most common infectious diseases, especially among adult refugees. When comparing the risks of infectious diseases between North Korean and Syrian refugees, it is critical to remember that Plasmodium vivax malaria has been endemic in North Korea, while cutaneous leishmaniasis has frequently been seen among Syrian migrants. Valuable datasets from health surveys of defectors were reviewed. In addition to tuberculosis and viral hepatitis, which were found to be the two most common infectious diseases, a special characteristic of North Korean defectors was Plasmodium vivax malaria. This needs to be added to the list of differential diagnoses for pyretic patients. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    2015-03-01

    Full Text Available Recently, I had the opportunity to discuss the liberation period and the Korean War with a PBS team that hopes to produce a documentary on this war. When I mentioned the Korean Truth and Reconciliation Commission and its painstaking work in documenting the myriad of massacres that occurred, they asked me, “What about North Korea? What about their massacres? Doesn’t this end up making the North look better than the South?” The implication was that political massacres, like everything else about the two Koreas, had to be molded in the vice of national division—and that if the North didn’t come off worse, as it always does in the American media, trouble might lie ahead. I said that the North did not have the imprimatur of the United Nations, or cardinal membership in the “free world,” or the continuous support of the United States. Someday, what the North has done will see the light of day, and then we can examine its record. Until then, one should not feel responsible for North Korean behavior, which is almost universally taken to be the worst in the world (whether true or not. Whatever blood is on North Korea’s hands is just that, on its hands. But as Americans we bear a deep responsibility for bringing into being and then supporting to the hilt a murderous regime. The easiest thing in the world is to denounce this or that North Korean crime. What is hard is to scrupulously examine a sordid history, with clear eyes and sincerity. In that way, the scholars in this special issue finally pay the occluded memories of thousands of victims and survivors what is simply their due.

  20. North Korea's satellite launch: provocation and ballistic progress

    International Nuclear Information System (INIS)

    2013-12-01

    North Korea's putting into orbit of a small meteorological satellite using an Unha-3 launcher on the 13 December 2013, a year on from Kim Jong-il's passing, smacks of provocation. The launch of an SLV that is closely related to the Taepodong-2 and that has numerous characteristics in common with a long-range ballistic missile contravened Security Council Resolutions 1695 (2006), 1718 (2006), and 1874 (2009), adopted in response to nuclear and ballistic tests carried out by Pyongyang. These resolutions implemented a progressively more strenuous regime of sanctions, which cannot fail to have marked the North Korean dictatorship, at least in economic and financial terms. The provisional successes and failures of the Six-party talks, mediated by China, which have been at a dead-end since 2009 bear witness to the unpredictability of the North's reactions. Pyongyang's double-agenda is, nonetheless, relatively easily to discern. Firstly, with this successful launch, North Korea has redeemed the failure of the first Unha-3 launch on the 13 April 2012, at the same time as Kim Jong-un took power and the country was celebrating the centenary of the birth of its founder, Kim Il-sung. This success evidently helps to bolster both the young leader's prestige on the domestic front and his sway over the army. Simultaneously, and beyond any symbolic value, North Korea's development of long-range ballistic capabilities constitutes veritable progress, on the back of a series of failures since 2006. Naturally, the reliability of the Unha-3 launcher (or of an improved Taepodong-2) is by no means guaranteed. Moreover, its payload is limited, since it can presently only launch small satellites, and thus well below the capacity needed to carry a nuclear weapon. If this is indeed North Korea's objective in years to come, it will need to make considerable technological progress, including the development of sufficiently small nuclear devices, which would necessitate further nuclear tests.

    Humanitarian agencies in North Korea operate within a complex sociopolitical environment historically characterized by a baseline of mistrust. As a result of operating within such a heated environment, health sector collaborations between such agencies and the North Korean government have followed unpredictable courses. The factors that have contributed to successful programmatic collaborations, as perceived by United States non-governmental organizations (NGOs) and North Korean officials were investigated. A qualitative, multi-case, comparative, research design using semistructured interviews was used. Expert North Korean informants were interviewed to generate a list of factors contributing to programmatic success, defined as fulfilling mutually established objectives through collaboration. The North Korean informants were asked to identify US NGOs that fulfill these criteria ("mission-compatible NGOs"). Representatives from all of the mission compatible NGOs were interviewed. All informants provided their perspectives on the factors that contributed to successful programmatic collaborations. The interviews were recorded, transcribed, and analyzed for thematic content. North Korean informants identified six mission-compatible US NGOs. The North Korean and US NGO informants provided a number of factors that contributed to successful programs. These factors were grouped into the following themes: (1) responsiveness to North Korean requests; (2) resident status; (3) program monitoring; (4) sincerity (apolitical objectives); (5) information gathering; and (6) interagency collaboration. Some US NGOs have devised innovative measures to work within a unique set of parameters in North Korea. Both US NGOs and North Korean authorities have made significant concessions to maintain their programmatic partnerships. In this manner, seasoned collaborators have employed creative strategies and a form of health diplomacy to facilitate programmatic success in North Korea by

    It is essential for Korea to enlarge nuclear energy utilization and development and to develop nuclear fuel cycle technology. However some domestic and international restraints are existing to achieve above goals. Therefore, the consideration for the environmental prospect of nuclear energy development is needed to solve those restraints. The current North Korea's policies and future relations between two countries in Korean peninsular in respect to domestic restraints are examined and forecasted in Chapter 2. This analysis tries to develop new approaches to solve internal and external major problems through forecasting the future on nuclear nonproliferation policy of U. S. An in-depth study on resolving international and inter-Korean restrictions in political and strategic perspectives is carried out in Chapter 3. The various policy alternatives to adjust the constraints of the joint declaration are proposed and analysed in Chapter. It contains also the national commitments that are suggested as ideas on how to advance the long-term nuclear research and development under the present situation. (author). 100 refs

  4. Intelligence and Nuclear Proliferation: Lessons Learned

    Hansen, Keith A.

    2011-09-01

    Intelligence agencies play a fundamental role in the prevention of nuclear proliferation, as they help to understand other countries' intentions and assess their technical capabilities and the nature of their nuclear activities. The challenges in this area remain, however, formidable. Past experiences and the discoveries of Iraq's WMD programs, of North Korean nuclear weapon program, and of Iranian activities, have put into question the ability of intelligence to monitor small, clandestine proliferation activities from either states or non-state entities. This Proliferation Paper analyzes the complex challenges intelligence faces and the various roles it plays in supporting national and international nuclear non-proliferation efforts, and reviews its track record. In an effort to shed light on the role and contribution of intelligence in national and international efforts to halt, if not prevent, further nuclear weapon proliferation, this paper first analyzes the challenges intelligence faces in monitoring small, clandestine proliferation activities and the role it plays in supporting non-proliferation efforts. It then reviews the intelligence track record in monitoring proliferation including the lessons learned from Iraq. Finally, it addresses whether it is possible for intelligence to accurately monitor future clandestine proliferation efforts. (author)

    A methodology of tsunami PSA was developed in this study. A tsunami PSA consists of tsunami hazard analysis, tsunami fragility analysis and system analysis. In the case of tsunami hazard analysis, evaluation of tsunami return period is major task. For the evaluation of tsunami return period, numerical analysis and empirical method can be applied. The application of this method was applied to a nuclear power plant, Ulchin 56 NPP, which is located in the east coast of Korean peninsula. Through this study, whole tsunami PSA working procedure was established and example calculation was performed for one of real nuclear power plant in Korea

    2003-01-01

    In 1991, the G. Bush administration decided to remove away all US surface tactic nuclear weapons everywhere in the world in order to reduce the nuclear warfare risk. This decision has led to the ratification by both Northern Korea and Southern Korea of the declaration on the denuclearization of the Korean peninsula, followed the same year by Mongolia which has become nuclear weapons free. As a consequence of these initiatives, the Center for international strategy, technology and policy (CISTP) of the Georgia institute of technology (Atlanta, USA) has decided the creation of a 'limited nuclear weapons free zone North-East Asia'(LNWFZ), based on cooperation, arms control and non-proliferation. This article describes the genesis of this inter-governmental process of informal diplomacy: proposal of creation of a league for non-nuclear states for North-East Asia, of implementation of an inspection regime and of a cooperative security community, of establishment of confidence building measures and of economic incentives. Then it describes the main components of the LNWFZ project and the obstacles that must be cleared away before its official implementation. (J.S.)

  9. Study on the Correlation between PSR and Korean Stress Test for Continued Operation of Aging NPP

    International Nuclear Information System (INIS)

    Chung, June Ho; Kim, Tae Ryong

    2013-01-01

    Nuclear Safety and Security Commission (NSSC), Korean nuclear regulatory authority established the stress test guideline based on the EU stress test, and KHNP prepared the execution plan in response to the guideline for the CO of Kori Unit 1 and Wolsong Unit 1. PSR is a comprehensive safety review program for long term operation of NPP, which was developed by IAEA. Korea adopted PSR in 1999 as the regulatory requirement for CO of NPP. The IAEA standard guideline for PSR program was updated in 2003. However, the Korean PSR has not been revised yet to apply the new IAEA guidelines. Additionally, national legal systems and guidelines associated with the adoption of stress tests are urgently required as well. These revisions are imperative in order to ensure the reliability of NPPs, and to promote public acceptance and understanding. This study presents the technical basis and proposals for review actions necessary to address the issues and controversies surrounding the continued operation and decommissioning of aging NPPs in Korea. As discussed earlier in characteristics of Korean Stress Test, it is more comprehensive than the EU Stress Test in terms of its multilateral evaluation which includes equipment durability, plant operation, human factors, and safety margins, hence substantially raising the significance and value of the evaluation process. Thus, the addition of Korean Stress Test to the existing Korean Evaluation of CO is expected to greatly increase the quality of safety assessment of aging NPPs in Korea due to its stricter safety policies, hence providing a more meaningful evaluation process. However, a one-time application of the Korean Stress Test to only Kori Unit 1 and Wolsong Unit 1 would be a waste of the great effort that has been done thus far to improve the Korean Evaluation of CO and develop the Korean Stress Test. By extending the Korean Stress Test to all NPPs in Korea would maintain and ensure the reliability of NPPs as well as public

  10. Nuclear Option in Korea

    2002-01-01

    With sixteen(16) operating nuclear units in Korea, the share of nuclear power generation reached 41% of the total electric power generation as of December 2000. A prediction is that it would further increase to 44.5% by year 2015 according to the national long term power development plan. Four units are currently under construction with 6 more units in order. With little domestic energy resource and increasing energy demand to support national economic growth, Korea has chosen nuclear power as one of the major energy sources to ensure stable power supply and to promote energy self-sufficiency. It has been recognized that nuclear power in Korea is not a selective option but rather a necessity. The Korean nuclear power development started with construction of a 600 MWe size reactor that was designed and constructed by foreign vendors. As the national grid capacity became larger, the size of nuclear units increased to 1000 MWe class. In the mean time, the need for nuclear technology self-reliance grew not only in operation and maintenance but also in construction, manufacturing and design. For this, a nuclear technology self-reliance program has been embarked with the support of the Government and utility, and the 1000 MWe class KSNP(Korean Standard Nuclear Power Plant) has been developed. The KSNPs are currently being designed, manufactured, constructed and operated by relevant Korean entities themselves. To fit into a larger capacity national grid and also to improve nuclear economic competitiveness, the 1400 MWe class KNGR(Korean Next Generation Reactor) design has been developed uprating the 1000 MWe KSNP design. Its construction project is currently under contract negotiation, and is planned to be finished by 2010. In the mean time, to be ready for future electric power market deregulation, the 600 MWe class small KSNP design is being developed downsizing the KSNP. A modular small size reactor, SMART(System Integrated Modular Advanced Reactor) is also being

    2009-01-01

    Periodic Safety Review (PSR) is a comprehensive study on a nuclear power plant safety, taking into account aspects such as operational history, ageing, safety analyses and advances in code and standards since the time of construction. In Korea, PSRs have been performed for 20 units and have been effectively used to obtain an overall view of actual plant safety to determine reasonable and practical modifications that should be made in order to obtain a higher level of safety approaching that of modern plants. Among many safety enhancements achieved from Korean PSRs, new safety analyses are the important methods to confirm plant safety by increasing safety margin for specific safety issues. Methods and effects of safety enhancements applied in Korean PSRs are reviewed in this paper in light of new safety analyses to obtain additional safety margins

    2006-01-01

    The purpose of this paper is to update the flooding PSA with Korean plant specific operating experience data and the appropriate estimation method for the flooding frequency to improve the PSA quality. The existing flooding PSA used the NPE (Nuclear Power Experience) database up to 1985 for the flooding frequency. They are all USA plant operating experiences. So an upgraded flooding frequency with Korean specific plant operation experience is required. We also propose a method of only using the PWR (Pressurized Water Reactor) data for the flooding frequency estimation in the case of the flooding area in the primary building even though the existing flooding PSA used both PWR and BWR (Boiled Water Reactor) data for all kinds of plant areas. We evaluate the CDF (Core Damage Frequency) with the modified flooding frequency and compare the results with that of the existing flooding PSA method

    The tritium concentrations of urine samples and the effective dose of the general Korean public were evaluated. To achieve accurate HTO analysis of urine samples, we established the optimal conditions for measuring the HTO content of urine samples. Urine samples from 50 Koreans who do not work at a nuclear facility were analyzed on the basis of the results. The average urine analysis result was 2.8 ±1 .4 Bq/L, and the range was 1.8-5.6 Bq/L. The measured values were lower than those reported for other countries. These results show that environmental factors and lifestyle differences are the main factors affecting the tritium level of the general public. © 2013 Elsevier Ltd. All rights reserved.

    The 3-D subsurface structure beneath the southern Korean Peninsula is poorly known, even though such information could be key in verifying or rejecting several competing models of the tectonic evolution of East Asia. We constructed a 3-D velocity model of the upper crust beneath the southern Korean Peninsula using 19 935 P-wave arrivals from 747 earthquakes recorded by high-density local seismic networks. Results show significant lateral and vertical variations: velocity increases from northwest to southeast at shallow depths, and significant velocity variations are observed across the South Korea Tectonic Line between the Okcheon Fold Belt and the Youngnam Massif. Collision between the North and South China blocks during the Early Cretaceous might have caused extensive deformation and the observed negative velocity anomalies in the region. The results of the tomographic inversion, combined with the findings of previous studies of Bouguer and isostatic gravity anomalies, indicate the presence of high-density material in the upper and middle crust beneath the Gyeongsang Basin in the southeastern Korean Peninsula. Although our results partially support the indentation tectonic model, it is still premature to discard other tectonic evolution models because our study only covers the southern half of the peninsula.

    The west coast of the Korean Peninsula is bounded by the Korean Bay to the north and the Yellow Sea to the south; the east coast is bounded by the East Sea. Two hundred kilometers separate the peninsula from eastern China. The Japanese islands of Honshu and Kyushu are located 206 kilometers to the southeast, just across the Korea Strait. Because of its unique geographical location, Chinese culture filtered into Japan through Korea; a common cultural sphere of Buddhism and Confucianism was thus established between the three countries. The total area of the peninsula, including the islands, is 222,154 square kilometers of which about 45 percent, excluding the area in the Demilitarized Zone, constitutes the territory of South Korea. There are about 3,000 islands belonging to Korea. The islands are located mostly around the Yellow Sea; Ulleungdo, the largest island in the East Sea, serves as a major fishery base as does Dokdo island. Important islands within South Korea territory include Jejudo, the largest island, which lies off the southwest corner of the peninsula, Geojedo, Ganghwado, and Namhaedo. Nearly 70 percent of the Korean Peninsula is covered by mountains and hills. Located mostly in the southern and the western regions, these hills give way gradually to increasingly higher mountains toward the eastern and the northern end. On the whole, the western and southern slopes of the peninsula are wide with some plains and basins along rivers, while the eastern slope is very narrow because the high mountains hug the East Sea coastline

  18. Aesthetics of Korean foods: The symbol of Korean culture

    Full Text Available Advances in transportation and communication have broken down critical barriers within the global economy, pushing us towards a more unified world. In keeping with this trend, processes of communication, transportation, and production are becoming increasingly standardized, mechanized, and automated. Yet as this global era of uniformity progresses, people and individuals will inevitably encounter identity confusion. Numerous individuals, ethnicities, nationalities, and countries around the world are working to counteract such identity confusion. As globalization progresses, groups and nationalities that fail to preserve their identities will dwindle and become absorbed by stronger entities. Therefore, many societies are investing great efforts into rediscovering and revamping their indigenous traditions, cultures, and customs. When travelers visit another country, one of the simplest avenues for them to experience the local culture is food. Unlike other cultural elements, many of which have become diluted because of globalization, native cuisines are still perceived as retaining the traditions, uniqueness, and diversity of individual cultures. It is more important than ever for people and countries to expand and preserve their respective cultural currencies. In this respect, taking a cultural approach to Korean cuisine is a fascinating and meaningful endeavor. In light of the recent publication of a few articles dealing with the symbolic significance and meaning behind Korean cuisine, an effort to compile a list of the distinctive cultural properties of Korean food seems vital. Furthermore, presenting the aesthetics of Korean food through a method that integrates science and culture is a very significant task. The authors of this paper firmly believe in its potential to advance the globalization of Korean food.

  19. A framework for verifying the dismantlement and abandonment of nuclear weapons. A policy implication for the denuclearization of Korea Peninsula

    2011-01-01

    Denuclearization of Korean Peninsula has been a serious security issue in the North East Asian region. Although the Six-Party Talks has been suspended since North Korea declared a boycott in 2008, aims of denuclearizing North Korea has still been discussed. For instance, the recent Japan and the U.S. '2+2' dialogue affirmed its importance to achieve complete and verifiable denuclearization of North Korea, including scrutinizing its uranium enrichment program, through irreversible steps under the Six Party process. In order to identify effective and efficient framework for denuclearization of North Korea, this paper examines 5 major denuclearization methods including (1) the Nunn-Luger Method, (2) the Iraqi Method, (3) the South African Method, (4) the Libyan Method and (5) the denuclearization method shown in the Nuclear Weapons Convention (NWC), while referring to the recent developments of the verification studies for nuclear disarmament, such as a joint research conducted by the United Kingdom and Norway and any other arguments made by disarmament experts. Moreover, this paper argues what political and security conditions will be required to make North Korea to accept intrusive verification for its denuclearization. Conditions for successful denuclearization talks among the Six-Party member states and a realistic approach of verifiable denuclearization will be also examined. (author)

    With rapidly changing dietary environment, dietary guidelines for Koreans were revised and relevant action guides were developed. First, the Dietary Guidelines Advisory Committee was established with experts and government officials from the fields of nutrition, preventive medicine, health promotion, agriculture, education and environment. The Committee set dietary goals for Koreans aiming for a better nutrition state of all after a thorough review and analysis of recent information related to nutritional status and/or problems of Korean population, changes in food production/supply, disease pattern, health policy and agricultural policy. Then, the revised dietary guidelines were proposed to accomplish these goals in addition to 6 different sets of dietary action guides to accommodate specific nutrition and health problems of respective age groups. Subsequently, these guidelines and guides were subjected to the focus group review, consumer perception surveys, and a public hearing for general and professional comments. Lastly, the language was clarified in terms of public understanding and phraseology. The revised Dietary guidelines for Koreans are as follows: eat a variety of grains, vegetables, fruits, fish, meat, poultry and dairy products; choose salt-preserved foods less, and use less salt when you prepare foods; increase physical activity for a healthy weight, and balance what you eat with your activity; enjoy every meal, and do not skip breakfast; if you drink alcoholic beverages, do so in moderation; prepare foods properly, and order sensible amounts; enjoy our rice-based diet.

    The results of our study revealed a local biologically relevant surface water contamination in the radionuclide anomaly in the north of Russia (Perm region) by means of Allium schoenoprasum L. anaphase-telophase chromosome aberration assay. This radionuclide anomaly was formed in 1971 as a result of an underground nuclear explosion with soil excavation. Specific activities of main dose-forming radionuclides in all examined reservoirs are below intervention levels officially adopted in Russia for drinking water. We found that {sup 90}Sr significantly contributes to induction of cytogenetic disturbances. Our previous data and the data described here suggest that metal and radionuclide combined exposure (with the dose below permissible exposure limits for human) may cause substantial biological effects. These effects are in part due to synergic response. The findings described here indicated that development of a new concept of radiation protection for humans and biota should be based on the clear understanding of biological effects of low doses of radiation in chronic exposure to multi-pollutant mixtures.

    The objective of this study was to determine if any excess of childhood leukaemia and non-Hodgkin's lymphoma was associated with certain striking examples of population mixing in rural Scotland produced by the North Sea oil industry. Details were traced for over 30 000 workers (25 yrs old) involved in the construction of the large oil terminals in the Shetland and Orkney islands in northern Scotland or employed offshore. Home addresses of the 17160 Scottish residents were postcoded, integrated with census data, and then classified as urban or rural. Rural postcode sectors, ranked by proportion of oil workers, were grouped into three categories with similar numbers of children but contrasting densities of oil workers. The incidence of leukaemia and non-Hodgkin's lymphoma was examined in these rural (and also in urban) categories in the periods 1974-8, 1979-83 and 1984-8. A significant excess of leukaemia and non-Hodgkin's lymphoma was found in 1979-83 in the group of rural home areas with the largest proportion of oil workers, following closely on large increases in the workforce. The area near the Dounreay nuclear installation, where an excess of leukaemia is already well known, was within the rural high oil category. (Author)

    Document available in abstract form only. Full text of publication follows: In the framework of the G8 Global Partnership the French Commission on Atomic Energy (CEA) is in charge of the French funded projects aimed to secure the materials susceptible to be a subject of the proliferation or a malicious use. The securing of the Spent Nuclear Fuel (SNF) from the former soviet submarines is of a special importance for CEA and the Russian Rosatom. Our main bilateral project has focused on two kinds of the SNF (alpha cores and VVR assemblies) stored at Gremikha, the former submarine base in the North-West of Russia. As of 2011 a significant results have been achieved: 2/3 of VVR type assemblies have been removed from Gremikha and reprocessed at PO Mayak. Nine alpha cores are unloaded and stored on at Gremikha. The main task now is to prepare the removal from Gremikha of all the remaining SNF and also to set up the needed infrastructure at the sites where this SNF will be moved. Substantial funding and technical assistance both from France and Russia will be required for that. Beyond the operator of the Gremikha site (SevRAO), the CEA and Rosatom involve many expert organizations from both countries such as AREVA, Kurchatov Institute and many others. Their contribution is one of the key elements of the success. (authors)

    To understand Korean immigrant women's common experiences and practices of utilizing health care services in the United States during childbirth. A qualitative interpretive phenomenological research design. Recruitment was conducted through advertisement on the MissyUSA.com website, which is the largest online community for married Korean women who live in North America. A purposive sample of 15 Korean immigrant women who experienced childbirth in the United States within the past 5 years was recruited. Data were collected using semistructured telephone interviews and were analyzed using the Heideggerian hermeneutical methodology. During childbirth in the United States, participants faced multifaceted barriers in unfamiliar sociocultural contexts yet maintained their own cultural heritages. They navigated the unfamiliar health care system and developed their own strategies to overcome barriers to health care access. Korean immigrant women actively sought health information on the Internet and through social networking during childbirth. Korean immigrant women selectively accepted new cultural beliefs with some modifications from their own cultural contexts and developed their own distinct birth cultures. Understanding a particular culture and respecting women's traditions, beliefs, and practices about their childbirth could help nurses to provide culturally sensitive care. © 2014 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Little is known about interest in faith-based health promotion programs among Asian American populations. Among the Christian denominations, the Seventh-day Adventist (SDA) church is known to place a strong doctrinal emphasis on health. To understand appropriate ways to develop and implement health promotion programs and to conduct research among Korean American SDAs. We collaborated with the North American Division of Korean SDA Churches which sponsors annual week-long religious retreats for their church members. We developed and administered a 10-page questionnaire at their 2009 retreat in order to assess socio-demographic and church characteristics, religiosity, perceived relationship between health and religion, and interest and preferences for church-based health promotion programs. Overall, 223 participants completed our survey (123 in Korean and 100 in English). The sample consisted of regular churchgoers who were involved in a variety of helping activities, and many holding leadership positions in their home churches. The vast majority was interested in receiving health information at church (80%) in the form of seminars, cooking classes and workshops (50-60%). Fewer respondents were interested in support groups (27%). Some interests and preferences differed between English and Korean language groups. Korean American SDA church retreat participants from a large geographic area are very interested in receiving health information and promoting health at their churches and can potentially serve as "agents of influence" in their respective communities.

    The energy supply in the countries, which have abundant energy resources, may not be affected by accepting the assertion of anti-nuclear and environment groups. Anti-nuclear movements in the countries which have little energy resources may cause serious problem in securing energy supply. Especially, it is distinct in Korea because she heavily depends on nuclear energy in electricity supply(nuclear share in total electricity supply is about 40%).The cause of social trouble surrounding nuclear energy is being involved with various circumstances. However, it is very important that we are not aware of the importance of information access and prepared for such a situation from the early stage of nuclear energy's development. In those matter, this paper analyzes the contents of nuclear information access system in France and Japan which have dynamic nuclear development program and presents the direction of the nuclear access regime through comparing Korean status and referring to progresses of the regime

    Organizational factors are referred to as the factors that influence the achievement of a goal of an organization. Latent problems of an organization could contribute to causing human errors in such stages as design, operation and maintenance, and furthermore, leading to an severe accident. In order to evaluate an organization from the safety viewpoint, it is necessary to identify the organizational factors in a systematic fashion. In this paper, some efforts to identify the organizational factors in Korean NPPs are presented. The study was performed in the following steps: 1) Reviewing the definitions and range of the organizational factors used by the previous 13 researches, 2) Structuring the organizational factors by screening and collating factors, 3) Analysing the organizational factors that is considered to have contributed to the trip events based on the trip report of Korean NPPs, 4) Suggesting a more reliable taxonomy of organizational factors for event analysis by applying the Onion Structure Model to the selected factors

    1996-01-01

    After the decision of extension of the Non Proliferation Treaty (NPT) in May 1995, the author first discusses strengths and weaknesses of the non proliferation regime. On the one side, the five nuclear powers are tight by international commitments, the number of proliferating countries has not increased, some countries have willingly decided to give up their military nuclear programme, ex-USSR republics have joined the NPT, the Israel-PLO agreement of 1993 initiated a new era, potentially proliferating countries do not have very significant nuclear programmes, shortcomings of international controls have been identified, international cooperation has improved, and control techniques are available. On the other hand, some matters of concern remain: lessons from the Gulf War, an apparently easier access to nuclear weapons, new opportunities of regional domination, a weaker American guarantee, the North-Korean problem, new exporters of nuclear and ballistic goods and technologies. In the next part, the author discusses the conditions of the agreement for an undefined extension of the NPT, and notably outlines what made this success possible. Then, she addresses political issues related to the universal character of the NPT and to nuclear disarmament. She also discusses the responsibility of the Five nuclear powers, the role of nuclear weapons, and the implication of the extension of the Treaty for the European Union

    It is hard to sum up Korean Shamanism in a few sentences but, in short, it could be described as the traditional syncretic folk religion of Korea. It mixes together ritual practices, beliefs, symbols and myths from Buddhism, Taoism, and folklore and adds elements commonly associated with nature religions and shamanism – including the use of techniques such as divination, trance, and mediumship. As with many other syncretic folk religions around the globe, there is very little in the way o...

    Highlights: • Dispersion of 129 I released from nuclear facilities evaluated by numerical modelling in the Atlantic. • Model validated through comparisons with field measurements. • 5.1 and 16.6 TBq of 129 I have been introduced in the Arctic from Sellafield and La Hague. • The distribution of 129 I among several shelf seas and regions has been evaluated. • Mean ages of tracers obtained: about 3.5 year larger for Sellafield than for La Hague releases. - Abstract: A quantitative evaluation of the fate of 129 I, released from the European reprocessing plants of Sellafield (UK) and La Hague (France), has been made by means of a Lagrangian dispersion model. Transport of radionuclides to the Arctic Ocean has been determined. Thus, 5.1 and 16.6 TBq of 129 I have been introduced in the Arctic from Sellafield and La Hague respectively from 1966 to 2012. These figures represent, respectively, 48% and 55% of the cumulative discharge to that time. Inventories in the North Atlantic, including shelf seas, are 4.4 and 13.8 TBq coming from Sellafield and La Hague respectively. These figures are significantly different from previous estimations based on field data. The distribution of these inventories among several shelf seas and regions has been evaluated as well. Mean ages of tracers have been finally obtained, making use of the age-averaging hypothesis. It has been found that mean ages for Sellafield releases are about 3.5 year larger than for La Hague releases

    Korea is no longer a safety area from nuclear terrorism. The reality of the Korean Peninsula requires a big change such as Korean mind, nuclear policy or international cooperative relationships. Therefore, there is a need to intensify military defense. To protect activation of nuclear terrorists, ROK special force who trained nuclear terror to suppress terror activists and fire fighters are well-educated to decontaminate are stationed near nuclear facilities. North Korea and terrorist groups are closed societies. Exact activity or aim is hard to acquire to analyze. Monitoring system is reinforced with high technology to deter their intention, Anti-nuclear movement is spread out across the world. They mostly use the peaceful demonstration, but extreme activists try to sabotage into the nuclear facilities. The government officials watch radical antinuclear and malicious groups. Nuclear facilities are very well installed security system. It is very difficult to sabotage without Insider support. The law makers have to make strong policy and for more effective prevention, Last but not least, authority should build the good relationship through education.

    U-Pb analyses were carried out on detrital zircon grains from major river-mouth sediments draining South Korea to infer provenance characteristics and the crustal growth history of the southern Korean Peninsula, using a laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS). The Korean Peninsula is located in the East Asian continental margin and mainly comprises three Precambrian massifs and two metamorphic belts in between them. We obtained 515 concordant to slightly discordant zircon ages ranging from ca. 3566 to ca. 48 Ma. Regardless of river-mouth location, predominance of Mesozoic (249e79 Ma) and Paleoproterozoic (2491e1691 Ma) ages with subordinate Archean ages in-dicates that the zircon ages reflect present exposures of plutonic/metamorphic rocks in the drainage basins of the South Korean rivers and the crustal growth of the southern Korean Peninsula was focused in these two periods. Comparison of detrital zircon-age data between the North and South Korean river sediments reveals that the Paleoproterozoic zircon age distributions of both regions are nearly identical, while the NeoproterozoicePaleozoic ages exist and the Mesozoic ages are dominant in southern Korean Peninsula. This result suggests that Precambrian terrains in Korea record the similar pre-Mesozoic magmatic history and that the influence of Mesozoic magmatism was mainly focused in South Korea.

    We used community-based participatory research (CBPR) to explore barriers to healthcare access and utilization and identify potentially effective intervention strategies to increase access among members of the Korean community in North Carolina (NC). Our CBPR partnership conducted 8 focus groups with 63 adult Korean immigrants in northwest NC and 15 individual in-depth interviews and conducted an empowerment-based community forum. We identified 20 themes that we organized into four domains, including practical barriers to health care, negative perceptions about care, contingencies for care, and provider misconceptions about local needs. Forum attendees identified four strategies to improve Korean community health. Despite the implementation of the Patient Protection and Affordable Care Act (ACA), many Korean community members will continue to remain uninsured, and among those who obtain insurance, many barriers will remain. It is imperative to ensure the health of this highly neglected and vulnerable community. Potential strategies include the development of (1) low-literacy materials to educate members of the Korean community about how to access healthcare services, (2) lay health advisor programs to support navigation of service access and utilization, (3) church-based programming, and (4) provider education to reduce misconceptions about Korean community needs.

    2001-01-01

    The purpose of this study is to compare the difference in health status between South Koreans and North Koreans and to identify factors responsible for the remarkable improvements in the health status of South Koreans. In order to examine the causes of the difference in health level, the health indices and their determinants of two Koreas were analyzed in time order. As of the year 2000, the average life expectancy at birth is 71.0 years for men and 78.6 years for women in South Korea, which is longer than that of North Korea by 8.1 for men and 11.2 for women. Infant mortality rate in 1998 was 9.0 per 1,000 live births in South Korea and 54.0 in North Korea. Since being liberated from Japanese ruling in 1945, South Korea has achieved remarkable economic growth under democracy and a market economy system. On the other hand, North Korea has maintained a socialistic system. North Korea has suffered from economic crisis since the 1990s. From this point it could be said that economic status is the major factor for the differences in health level between the two Koreas. Economic status not only directly influences health level but also indirectly affects it through influences on nutrition, hygiene, health resources, and other intervening factors. The South Korean government has concentrated its limited resources on public health activities such as tuberculosis control, family planning (FP), and maternal and child health (MCH) programmes whereas the private sector has taken charge of constructing the health delivery system including health facilities and human resources. In order to solve the problem, which might occur in the private-oriented medical care system, the South Korean government has introduced the national health insurance programme and enforced regulation policies. Many developing countries which are suffering from poverty and disease, can learn from the experience of Korea that had suffered from similar problems up to the early 1970s.

    2014-07-01

    Increasing cultural diversity in the United States and significant health disparities among immigrant populations make acculturation an important concept to measure in health research. The purpose of this cross-sectional, descriptive study was to examine acculturation and health of Korean American adults. A convenience sample of 517 Korean American adults in a Midwestern city completed a survey in either English or Korean. All four groups of Berry's acculturation model were identified using cluster analysis with Lee's Acculturation Scale. Assimilation, integration, and separation were found in the English survey sample, whereas integration, separation, and marginalization were found in the Korean survey sample. Moreover, the findings revealed that acculturation is a bidimensional process, and the unique nature of samples may determine acculturation groups. Physical health and mental health were significantly related to acculturation in the English survey sample. However, there was not a significant relationship between health and acculturation in the Korean survey sample. © The Author(s) 2014.
