The Chernobyl accident has seriously affected development of the USSR nuclear power program. But it has not eliminated the basic prerequisites for nuclear power development in the USSR which are: - resources and consumption territorial disproportions; - large share of oil and gas in electricity generation; - negative ecological aspects of coal plants; - high power industry development rate. At the same time it has aggravated the old problems and has given rise to some new-ones of which the most important are: - increased safety requirements; rise in costs; longer construction schedules; public opinion. On the whole for further safe development of nuclear power a detailed analysis of the Chernobyl accident is required, including studies of long-term accident consequences and measures of their mitigation and elimination. A necessary condition for NPP operation to be continued would also be development and rapid implementation of technical approaches which would permit to eliminate the design shortcomings in the RBMK NPPs both operating and those under construction. At the same time we have to ensure their competitiveness with other energy sources and possibility of expansion of their applications. The problem of public opinion should be emphasised. After the Chernobyl accident we have faced a social phenomenon which is quite new in this country. There is almost no site where the population was not opposed to NPP construction. For us these problems are especially difficult as we have had no experience of this kind of interactions with the public. We are planning and begin to realize a program basing on the current world experience. This program includes primarily a wide series of publications on the problems of nuclear energy its ecologic and economic advantages as compared with conventional and alternative energy sources,, using all cur-rent media.

The accident at the Chernobyl, Ukraine, nuclear reactor on 26 April 1986 released large amounts of radiocesium and other radionuclides into the environment, contaminating much of the northern hemisphere, especially Europe. In the vicinity of Chernobyl, at least 30 people died, more than 115,000 others were evacuated, and consumption of milk and other foods was banned because of radiocontamination. At least 14,000 human cancer deaths are expected in Russia, Belarus, and the Ukraine as a direct result of Chernobyl. The most sensitive local ecosystems, as judged by survival, were the soil fauna, pine forest communities, and certain populations of rodents. Elsewhere, fallout from Chernobyl significantly contaminated freshwater and terrestrial ecosystems and flesh and milk of domestic livestock; in many cases, radionuclide concentrations in biological samples exceeded current radiation protection guidelines. Reindeer (Rangifer tarandus) in Scandinavia were among the most seriously afflicted by Chernobyl fallout, probably because their main food during winter (lichens) is an efficient absorber of airborne particles containing radiocesium. Some reindeer calves contaminated with 137Cs from Chernobyl showed 137Cs-dependent decreases in survival and increases in frequency of chromosomal aberrations. Although radiation levels in the biosphere are declining with time, latent effects of initial exposure--including an increased frequency of thyroid and other cancers--are now measurable. The full effect of the Chernobyl nuclear reactor accident on natural resources will probably not be known for at least several decades because of gaps in data on long-term genetic and reproductive effects and on radiocesium cycling and toxicokinetics.

Consequences of the nuclear power plant accident at Chernobyl

1991-01-01

The Chernobyl Nuclear Power Plant accident, in the Ukrainian Soviet Socialist Republic (SSR), on April 26, 1986, was the first major nuclear power plant accident that resulted in a large-scale fire and subsequent explosions, immediate and delayed deaths of plant operators and emergency service workers, and the radioactive contamination of a significant land area. The release of radioactive material, over a 10-day period, resulted in millions of Soviets, and other Europeans, being exposed to measurable levels of radioactive fallout. Because of the effects of wind and rain, the radioactive nuclide fallout distribution patterns are not well defined, though they appear to be focused in three contiguous Soviet Republics: the Ukrainian SSR, the Byelorussian SSR, and the Russian Soviet Federated Socialist Republic. Further, because of the many radioactive nuclides (krypton, xenon, cesium, iodine, strontium, plutonium) released by the prolonged fires at Chernobyl, the long-term medical, psychological, social, and economic effects will require careful and prolonged study. Specifically, studies on the medical (leukemia, cancers, thyroid disease) and psychological (reactive depressions, post-traumatic stress disorders, family disorganization) consequences of continued low dose radiation exposure in the affected villages and towns need to be conducted so that a coherent, comprehensive, community-oriented plan may evolve that will not cause those already affected any additional harm and confusion

Could a 'Chernobyl' nuclear disaster happen here?

1986-01-01

At 1.23 a.m. (Soviet European Time) on Saturday 26 April 1986 an accident occurred in reactor number four of the Chernobyl Nuclear Power-Station in the Ukrainian Soviet Socialist Republic. The hydrogen in the core of the reactor exploded while the reactor was being shut down for routine maintenance, and a cloud of radioactivity was blasted high into the atmosphere. The radioactive plume drifted north-westwards to Sweden where, on 28 April, a radiation detector at the Forsmark nuclear complex gave the first public warning of the Chernobyl disaster. South Africa possesses one nuclear power-station, at Koeberg some 30 kilometres north of Cape Town. Is Koeberg safe? Could a Chernobyl-style disaster occur here? The difference in design between the Chernobylsk-4 reactor and Koeberg reactor is discussed. Differences in the design of the two power-stations preclude the same type of accident from happening at Koeberg. The chances of an accident affecting the environment seriously remain remote, given a design philosophy which includes minimising the possibility of an accident, containing it should it happen, and pre-planning the emergency response in case it cannot be contained. That, in a nutshell, is why we believe Koeberg will never become a 'Chernobyl'

The problems of nuclear safety as a complex system are considered. It is shown that the reliability and safety of a nuclear power plant determined does not only reliable structures of the main equipment and qualification of the staff, but especially strict compliance with the priorities of the Security over the economic, political and other factors. Failure to observe this principle has become a real cause of several accidents in the global nuclear power industry, accompanied by the release of radionuclides into the environment. The lessons of Chernobyl remain unlearned, what confirmed the accident at the Fukushima-1 in Japan. The most important of these is the readiness to respond and protect the public, not only from radiation, but also from a psychological stress.

1987-12-01

This report presents the compilation of information obtained by various organizations regarding the accident (and the consequences of the accident) that occurred at Unit 4 of the nuclear power station at Chernobyl in the USSR on April 26, 1986. Each organization has independently accepted responsibility for one or more chapters. The specific responsibility of each organization is indicated. The various authors are identified in a footnote to each chapter. Very briefly the other chapters cover: the design of the Chernobyl nuclear station Unit 4; safety analyses for Unit 4; the accident scenario; the role of the operator; an assessment of the radioactive release, dispersion, and transport; the activities associated with emergency actions; and information on the health and environmental consequences from the accident. These subjects cover the major aspects of the accident that have the potential to present new information and lessons for the nuclear industry in general. The task of evaluating the information obtained in these various areas and the assessment of the potential implications has been left to each organization to pursue according to the relevance of the subject to their organization. Those findings will be issued separately by the cognizant organizations. The basic purpose of this report is to provide the information upon which such assessments can be made

Chernobyl coverage: how the US media treated the nuclear industry

This study attempted to uncover whether enough background information about nuclear power and the nuclear industries in the USA, USSR and Eastern and Western Europe had been included during the first two weeks of US coverage of the Chernobyl accident so that Americans would not be misled in their understanding of and attitudes toward nuclear power in general. It also sought to determine if reporters took advantage of the Chernobyl accident to attack nuclear technology or the nuclear industry in general. Coverage was analysed in five US newspapers and on the evening newscasts of the three major US television networks. Despite heavy coverage of the accident, no more than 25% of the coverage was devoted to information on safety records, history of accidents and current status of nuclear industries. Not enough information was provided to help the public's level of understanding of nuclear power or to put the Chernobyl accident in context. However, articles and newscasts generally balanced use of pro- and anti-nuclear statements, and did not include excessive amounts of fear-inducing and negative information. (author)

Cardiovascular system state was assessed in rescuers of various age groups (107 men 44% - 24-39 years old, 39% - 40-49 years old, 17% - 50-63 years old) at the Chernobyl Nuclear Power Plant. All the rescuers were subjected to external uniform low dose γ-radiation (up to 50 rem). A high percent of hyperternsion was detected in rescuers aged up to 39 years old resulting from strong psychoemotional tension and radiophobia in the course of the Chernobyl accident response. Data on the affect of external low dose γ-radiation on cardiovascular system were not established

Sweden received about 5 % of the total release of (137)Cs from the Chernobyl nuclear power plant accident in 1986. The distribution of the fallout mainly affected northern Sweden, where some parts of the population could have received an estimated annual effective dose of 1-2 mSv per year. It is disputed whether an increased incidence of cancer can be detected in epidemiological studies after the Chernobyl nuclear power plant accident outside the former Union of Soviet Socialist Republics. In the present paper, a possible exposure-response pattern between deposition of (137)Cs and cancer incidence after the Chernobyl nuclear power plant accident was investigated in the nine northernmost counties of Sweden (2.2 million inhabitants in 1986). The activity of (137)Cs from the fallout maps at 1986 was used as a proxy for the received dose of ionizing radiation. Diagnoses of cancer (ICD-7 code 140-209) from 1980 to 2009 were received from the Swedish Cancer Registry (273,222 cases). Age-adjusted incidence rate ratios, stratified by gender, were calculated with Poisson regression in two closed cohorts of the population in the nine counties 1980 and 1986, respectively. The follow-up periods were 1980-1985 and 1986-2009, respectively. The average surface-weighted deposition of (137)Cs at three geographical levels; county (n = 9), municipality (n = 95) and parish level (n = 612) was applied for the two cohorts to study the pre- and the post-Chernobyl periods separately. To analyze time trends, the age-standardized total cancer incidence was calculated for the general Swedish population and the population in the nine counties. Joinpoint regression was used to compare the average annual percent change in the general population and the study population within each gender. No obvious exposure-response pattern was seen in the age-adjusted total cancer incidence rate ratios. A spurious association between fallout and cancer incidence was present, where areas with the

This leaflet has been prepared by the Central Electricity Generating Board. Following the accident at Chernobyl nuclear power station in the Soviet Union people are concerned about the safety of the UK's nuclear power stations. This leaflet explains that Chernobyl is unlike any nuclear station operating or planned in the UK and under the CEGB's stringent safety rules it could not have been built in the UK. The leaflet explains what happened at Chernobyl and compares the RBMK design and British reactors. The bodies concerned with reactor safety are noted. The containment of radioactivity and emergency procedures are explained. The PWR design for Sizewell-B is stated to be much safer than the RBMK Chernobyl design. (UK)

A visit to Chernobyl by Western experts was organized within the 1995 Nuclear Technology Conference. The region, which had been evacuated after the reactor accident in the Chernobyl-4 nuclear generating unit on April 26, 1986, now again offers employment to some 15,000 people. 120 scientific organizations are conducting studies in the protected zone. No indications of any consequences of the accident can be seen in the natural environment. As the manager of the power plant put it: 'This is a good region to live in.' In order to maintain this standard of living, the agencies responsible in Ukraine plan to repair unit 2, which has been down because of a fire in the turbine building since 1991, resynchronize it with the power grid, and run it up until 2002. Unit 1 is to be decommissioned in 1998; unit 3, in 2001. The biggest problem on site is the stability of the sarcophagus around unit 4. (orig./UA) [de

The accident at the Nuclear Power Plant in Chernobyl create a new problem for health professionals in Latvia due to the fact that 6475 inhabitants (mainly healthy and men of reproductive age) of Latvia took part in clear-up works in Chernobyl within the period 1986-1991. Chernobyl clear-up workers were exposed γ-radiation and they also incorporated radionuclides. The doses documented for the clear-up workers are variable; they are estimated to be between 0.01-0.5 Gy although the specialists working on the precision of received doses think that they could be even 2 or 3 times higher. The aim of this work is to evaluate the health status of liquidators investigating them on a long-term basis: to create the correct system of health status evaluation of Chernobyl clear-up workers, to improve the register of Chernobyl clear-up workers and of their children, to analyze the data about the incidence of different diseases and mortality gained from follow-ups, to evaluate health status and clinical picture within the period of time, to work out and use adequate methods of treatment. Chernobyl clear-up workers more often than the control group suffer from diseases of the nervous, the endocrine and the metabolic and immune system. They also have higher rate of incidence for diseases of digestive and respiratory system and for diseases of bones, muscles and connective tissue higher rates of accidents and suicides. Now, ten years after the accident there are Chernobyl clear-up workers who are chronically ill and their health status is expected to be worse in the next few years. Regular follow-up and medical examination of Chernobyl clear-up workers and their children should be carried out every year. Regular rehabilitation of Chernobyl clear-up workers should be provided by the government

Nuclear power production in the Ukraine started in 1977 with the startup of the first 1000-MW power-generating unit at the Chernobyl nuclear power plant. During the period from 1977 to 1989 sixteen power-generating units with a total electric capacity of 14,880 MW were put into operation at five nuclear power plants: ten VVER-1000, two VVER-440, and four RBMK-1000. As a result of the accident in 1986 in the fourth power-generating unit and the fire in 1991 in the second power-generating unit of the Chernobyl nuclear power plant, these units are no longer operating. Therefore the total installed nuclear power plant capacity is 12,880 MW. Moreover, the construction of three more power-generating units with VVER-1000 reactors is almost completed at three nuclear power plants - Zaporozh'e, Roven, and Khmel'nitsk. These units are not in operation because of the moratorium announced by the Supreme Council of Ukraine. In connection with the Council's decision, the Chernobyl nuclear power plant should have been shut down in 1993

Gale, R.P.

1987-01-01

The immediate medical response to the nuclear accident at the Chernobyl nuclear power station involved containment of the radioactivity and evacuation of the nearby population. The next step consisted of assessment of the radiation dose received by individuals, based on biological dosimetry, and treatment of those exposed. Medical care involved treatment of skin burns; measures to support bone marrow failure, gastrointestinal tract injury, and other organ damage (i.e., infection prophylaxis and transfusions) for those with lower radiation dose exposure; and bone marrow transplantation for those exposed to a high dose of radiation. At Chernobyl, two victims died immediately and 29 died of radiation or thermal injuries in the next three months. The remaining victims of the accident are currently well. A nuclear accident anywhere is a nuclear accident everywhere. Prevention and cooperation in response to these accidents are essential goals

On the morning of April 26, 1986, Unit 4 of the Chernobyl Nuclear Power Plant (Ukraine, USSR) suffered an accident of the greatest magnitude among those which have taken place in nuclear energy installations employed for peaceful uses. The accident reached a degree of severity unknown up to now in nuclear energy generating plants, both with respect to the loss of human lives and the effects caused to the neighboring population (as well as to other nations within a wide radius of radioactivity dispersal), and also with respect to the damage caused in the nuclear plant itself. In the light of the anxiety created internationally, the USSR State Committee for the Utilization of Atomic Energy prepared a report (1), based on the conclusions of the Governmental Commission entrusted to study the causes of the accident, which was presented at the international meeting of experts held at the International Atomic Energy Agency (IAEA) headquarters in Vienna from August 25 to 29, 1986. The present technical report has been prepared by the Spanish nuclear power plants within the framework of UNIDAD ELECTRICA, S.A.

The Chernobyl accident and the Spanish nuclear power plants. Technical report

International Nuclear Information System (INIS)

1986-11-01

On the morning of April 26, 1986, Unit 4 of the Chernobyl Nuclear Power Plant (Ukraine, USSR) suffered an accident of the greatest magnitude among those which have taken place in nuclear energy installations employed for peaceful uses. The accident reached a degree of severity unknown up to now in nuclear energy generating plants, both with respect to the loss of human lives and the effects caused to the neighboring population (as well as to other nations within a wide radius of radioactivity dispersal), and also with respect to the damage caused in the nuclear plant itself. In the light of the anxiety created internationally, the USSR State Committee for the Utilization of Atomic Energy prepared a report (1), based on the conclusions of the Governmental Commission entrusted to study the causes of the accident, which was presented at the international meeting of experts held at the International Atomic Energy Agency (IAEA) headquarters in Vienna from August 25 to 29, 1986. The present technical report has been prepared by the Spanish nuclear power plants within the framework of UNIDAD ELECTRICA, S.A. (UNESA) - the Association of Spanish electric utilities - in collaboration with EMPRESARIOS AGRUPADOS, S.A. The report reflects the utilities' analyses of the causes and consequences of the accident and, based on similarities and differences with Spanish plants under construction and in operation, intends to: a. Evaluate the possibility of an accident with similar consequences occurring in a Spanish plant b. Identify possible design and operation modifications indicated by the lessons learned from this accident

This report discusses a number of effects of the Chernobyl-accident on public opinion about nuclear power. The analysis is based on a comparison of a survey conducted shortly after Chernobyl and a number of measurements in the Netherlands between 1982 and 1986. The conclusions can be summarized as follows: Attitudes towards nuclear power and especially towards building new stations have become much more negative after the disaster in Chernobyl. Although a majority of the population now wants to close existing nuclear power stations, there appears strong support for continuation of nuclear research. The structure of the nuclear debate has not changed fundamentally. Supporters and opponents have kept the same demographic characteristics. The arguments which distinguish them have not changed, except that the expectation of a serious accident has an increased impact on attitudes. A majority of the population felt the information after the accident not sufficient. Since 1982 attitudes towards coal also have become more negative, mainly as a consequence of the higher visibility of effects of acid rain. (Auth.)

After Chernobyl - Consequences for energy policy, nuclear safety, radiation and environmental protection. Report of the Expert Group for Nuclear Safety and the environment

Energy Technology Data Exchange (ETDEWEB)

1986-01-01

Chapter B contains a report on the current situation with regard to international nuclear power development, nuclear safety programmes. Swedish emergency preparedness planning, and the phasing out of nuclear power. Chapter C explains the causes of the Chernobyl accident and its course and effects in the Soviet Union. The chapter also contains a summary of earlier reactor accidents, a comparison between the Chernobyl reactor and Swedish reactors, and a discussion of the conclustions that can be drawn with respect to the Swedish reactor safety programme. Chapter D begins with an account of certain basic concepts related to radioactive substances and radiation, our radiological environment, and the effects of radiation. Then follows an account of the risks of nuclear power, and in particular the effects of the Chernobyl accident in Sweden. The Expert Group urges that careful consideration be given to the question of further reinforcement of and other measures concerning preparedness for nuclear power accidents on the basis of the material now available, including the evaluation of emergency operations after the Chernobyl accident. Twelve nuclear power blocks now in operation may be used insofar as safety criteria permit. The Expert Group presents the conditions for and consequences of some alternative, faster phase-out schedules. Chapter E begins with an account of the available substitutes for nuclear power. Different phase-out schedules are then presented. The chapter closes with an estimate of the consequences for the national economy. In Chapter F the Expert Group present a description of risks and environmental problems in relation to the alternative phase-out schedules. (authors).

Nuclear power in Japan

The Japanese movement against nuclear energy reached a climax in its upsurge in 1988 two years after the Chernobyl accident. At the outset of that year, this trend was triggered by the government acknowledgement that the Tokyo market was open to foods contaminated by the fallout from Chernobyl. Anti-nuclear activists played an agitating role and many housewives were persuaded to join them. Among many public opinion surveys conducted at that time by newspapers and broadcasting networks, I would like to give you some figures of results from the poll carried out by NHK: Sixty percent of respondents said that nuclear power 'should be promoted', either 'vigorously' 7 or 'carefully' 53%). Sixty-six percent doubted the 'safety of nuclear power', describing it as either 'very dangerous' 20%) or 'rather dangerous' (46%). Only 27% said it was 'safe'. In other words, those who acknowledged the need for nuclear power were almost equal in number with those who found it dangerous. What should these figures be taken to mean? I would take note of the fact that nearly two-thirds of valid responses were in favor of nuclear power even at the time when public opinion reacted most strongly to the impact of the Chernobyl accident. This apparently indicates that the majority of the Japanese people are of the opinion that they would 'promote nuclear power though it is dangerous' or that they would 'promote it, but with the understanding that it is dangerous'. But the anti-nuclear movement is continuing. It remains a headache for both the government and the electric utilities. But we can regard the anti-nuclear movement in Japan as not so serious as that faced by other industrial nations

Analysis of changes in public opinion during the period after the Chernobyl accident is given. It is noted that under the conditions of economical crisis the ecological problems were set aside to the periphery of the public attention in Russia. However in view of some specialists certain positive changes in nuclear power developments took place. Decisions on construction of new power units, completion of conserved NPPs, etc. started to be realized. It is noted that establishment of relations between nuclear specialists and journalists, parliament members and representatives of regional public organizations is most important at the current stage

The issue of safety of Ukraine's Nuclear Power Plants attracts a particular attention world-wide, and the reasons for that are clearly understood: the memories of the Chernobyl tragedy happened in 1986 will possess the minds of people of the world for years. The international community is aware that the political changes and transient economy crisis the former Soviet Union States are facing today, make the resolution of nuclear facilities safety problems less possible. Nevertheless, the understanding and perception of safety policy in Ukraine underwent drastic changes after the Chernobyl accident, and the policy pursued by the Ukraine's safety authority contributes to turning the changes into good practices

The nuclear accident at Chernobyl was the worst in the history of nuclear power. It tested the organized medical response to mass radiation casualties. This article reviews the Soviet response as reported at the 1986 postaccident review meeting in Vienna and as determined from interviews. The Soviets used three levels of care: rescue and first aid at the plant site; emergency treatment at regional hospitals; and definitive evaluation and treatment in Moscow. Diagnosis, triage, patient disposition, attendant exposure, and preventive actions are detailed. The United States would be well advised to organize its resources definitively to cope with future nonmilitary nuclear accidents

The report contains a presentation of the Chernobyl' nuclear power station and of the RBMK-1000 reactor, including its principal physical characteristics, the safety systems and a description of the site and of the surrounding region. After a chronological account of the events which led to the accident and an analysis of the accident using a mathematical model it is concluded that the prime cause of the accident was an extremely improbable combination of violations of instructions and operating rules committed by the staff of the unit. Technical and organizational measures for improving the safety of nuclear power plants with RBMK reactors have been taken. A detailed description of the actions taken to contain the accident and to alleviate its consequences is given and includes the fire fighting at the nuclear power station, the evaluation of the state of the fuel after the accident, the actions taken to limit the consequences of the accident in the core, the measures taken at units 1, 2 and 3 of the nuclear power station, the monitoring and diagnosis of the state of the damaged unit, the decontamination of the site and of the 30 km zone and the long-term entombment of the damaged unit. The measures taken for environmental radioactive contamination monitoring, starting by the assessment of the quantity, composition and dynamics of fission products release from the damaged reactor are described, including the main characteristics of the radioactive contamination of the atmosphere and of the ground, the possible ecological consequences and data on the exposure of plant and emergency service personnel and of the population in the 30 km zone around the plant. The last part of the report presents some recommendations for improving nuclear power safety, including scientific, technical and organizational aspects and international measures. Finally, an overview of the development of nuclear power in the USSR is given

Decommissioning of nuclear power plants and other nuclear fuel cycle facilities has been an imperative issue lately. There exist significant experience and generally accepted recommendations on remediation of lands with residual radioactive contamination; however, there are hardly any such recommendations on remediation of cooling ponds that, in most cases, are fairly large water reservoirs. The literature only describes remediation of minor reservoirs containing radioactive silt (a complete closure followed by preservation) or small water reservoirs resulting in reestablishing natural water flows. Problems associated with remediation of river reservoirs resulting in flooding of vast agricultural areas also have been described. In addition, the severity of environmental and economic problems related to the remedial activities is shown to exceed any potential benefits of these activities. One of the large, highly contaminated water reservoirs that require either remediation or closure is Karachay Lake near the MAYAK Production Association in the Chelyabinsk Region of Russia where liquid radioactive waste had been deep well injected for a long period of time. Backfilling of Karachay Lake is currently in progress. It should be noted that secondary environmental problems associated with its closure are considered to be of less importance since sustaining Karachay Lake would have presented a much higher radiological risk. Another well-known highly contaminated water reservoir is the Chernobyl Nuclear Power Plant (ChNPP) Cooling Pond, decommissioning of which is planned for the near future. This study summarizes the environmental problems associated with the ChNPP Cooling Pond decommissioning

Nuclear power and public opinion in Russia

The attitude of the Russian (Soviet) society towards nuclear power and nuclear technology has changed over the years, depending on political, social and economic processes. Three periods of the relationship between the Russian society and nuclear power can be distinguished. The first period began in the early 1940s and finished in April 1986, when the Chernobyl disaster occurred. It was the period of vigorous development of the nuclear industry in the USSR. During this period the population unconditionally supported the development of this branch of the industry. The second period lasted from 1986 to 1991. The paper analyses the attitude towards nuclear power of the Soviet society as a whole and of separate social groups during the period of 'glasnost' (openness) and during the disintegration period. It is pointed out that the Chernobyl syndrome and the consequent anti-nuclear trends were used in the struggle for power. The third period extends from 1991 to the present. The paper analyses the causes of the positive changes in the public towards nuclear power which have been evident from sociological surveys. (author)

The Chernobyl syndrome

The nuclear industry has failed in its communication with the public in the past. This failure has affected public reaction to the Chernobyl disaster. It has also alerted the nuclear industry to this failure and it will concentrate efforts to get the nuclear message over more effectively. At the moment the nuclear industry and the public interpret the same statements in different ways. This was evident after the Chernobyl accident. The author explains that the industry can only restore public confidence in nuclear power by being open, honest and speaking in terms that lay people can understand. (UK)

International nuclear law in the 25 years between Chernobyl and Fukushima and beyond

International Nuclear Information System (INIS)

Selma Kus

2011-01-01

This paper is dedicated both to legal developments since the accident at the Chernobyl nuclear power plant 25 years ago and possible legal implications of the accidents at Fukushima Daiichi which occurred after Japan was struck by a devastating earthquake on 11 March 2011. Following the accident at Three Mile Island in 1979 and at Chernobyl in 1986, Fukushima will be remembered as the third major accident in the history of civilian nuclear power reactors. Yet Chernobyl was and remains the worst trauma in this history as a result of which nuclear developments slowed down significantly. Eventually, the industry emerged as a safer and stronger technology, particularly because the 25 years between Chernobyl and Fukushima were marked by an exceptional national and international commitment to nuclear safety and emergency preparedness so as to prevent accidents and minimise potential damages, if such occur. From a legal point of view it is safe to say that the nuclear industry is one of the most strictly regulated. However, it is equally safe to say that there is no zero risk technology and that accidents can happen. For several weeks after the tragic events in Japan the world's focus turned - justifiably so - to the Fukushima Daiichi nuclear power units. It was nevertheless astonishing to observe that the real tragedy, the terrible loss of lives, swept away villages, and the chaos following the breakdown of all kinds of infrastructure were treated as a sideshow compared with the dramatic images of explosions at the Fukushima Daiichi units and helicopters trying to drop seawater into the spent fuel pools. The live broadcasting of accidents might present one of the first lessons to be learnt in our Internet and 24-hour news channel era which did not exist at the time of Chernobyl. The international legal community will also face challenges as the accident has put 25 years of international co-operation and international nuclear law-making to its first serious test. The

Chernobyl dumped significant quantities of radioactive fallout as far as 1,300 miles away, causing severe economic loss in nations stretching from Sweden to Greece. It cost innocent sheep growers in Wales, fishermen in Switzerland, reindeer-dependent Laplanders in Norway, dairymen in Sweden and Austria, and cheese makers in Greece. European nations have calculated costs from deposition of nuclear materials in the hundreds of millions report the authors. The accident at chernobyl and the European experience with the consequences can offer several insights relevant to the US commercial nuclear industry, the authors note: (1) the aggregate effect of such an accident is extremely large and unpredictable; (2) adequate disaster planning can significantly reduce costs and ease the disruption; and (3) the experience raises questions about the adequacy of the nation's nuclear insurance and liability programs. given the number of commissioned nuclear reactors today, the present scheme would provide financial compensation of approximately $7 billion per incident. Depending on the circumstances, the authors say this may not be sufficient

The disaster had an poisonous impact on people's health and ambitions, it also gave birth to a new vision on the impact of the human factor on the universe. The post Chernobyl society is an alarming sign as regarding the human surviving perspectives, and a violent lesson on the 'global biography'. (author)

Radioactive release during nuclear accidents in Chernobyl and Fukushima

Science.gov (United States)

Nur Ain Sulaiman, Siti; Mohamed, Faizal; Rahim, Ahmad Nabil Ab

2018-01-01

Nuclear accidents that occurred in Chernobyl and Fukushima have initiated many research interests to understand the cause and mechanism of radioactive release within reactor compound and to the environment. Common types of radionuclide release are the fission products from the irradiated fuel rod itself. In case of nuclear accident, the focus of monitoring will be mostly on the release of noble gases, I-131 and Cs-137. As these are the only accidents have been rated within International Nuclear Events Scale (INES) Level 7, the radioactive release to the environment was one of the critical insights to be monitored. It was estimated that the release of radioactive material to the atmosphere due to Fukushima accident was approximately 10% of the Chernobyl accident. By referring to the previous reports using computational code systems to model the release rate, the release activity of I-131 and Cs-137 in Chernobyl was significantly higher compare to Fukushima. The simulation code also showed that Chernobyl had higher release rate of both radionuclides on the day of accident. Other factors affecting the radioactive release for Fukushima and Chernobyl accidents such as the current reactor technology and safety measures are also compared for discussion.

The Chernobyl nuclear disaster resulted in contamination of vast areas in Europe. To date, there is little knowledge about the effects of radioactive contamination on tick species. We sampled ticks from vegetation and large-sized wild mammals belonging to orders Carnivora and Artiodactyla at sites with 0.76, 1.91, and 4.50 mSv/hr ionizing radiation background values in the Polesky State Radio-Ecological Reserve of the Chernobyl nuclear disaster zone in spring 2010. Altogether, 122 questing ticks were collected from vegetation. Among collected ticks, Dermacentor reticulatus (Fabricius) was, by far, the most abundant species (99.2%), followed by Ixodes ricnus (L.) (0.8%), which was collected only at the 0.76 mSv/hr site. The average sex ratio female∶male was 2.9∶1.0. In parallel with the present study, we examined 3 Sus scrofa (L.), 2 Nyctereutes procyonoides (Gray), and 1 Alces alces (L.) at the 4.50 mSv/hr site; 96 D. reticulatus ticks were found on 2 N. procyonoides specimens. The mean density and the intensity of infestation were 16 ticks per animal and 48 ticks per infested animal, respectively. Future investigations are warranted to further characterize the role of various tick vectors, vertebrate reservoirs, and diversity of tick-borne pathogens in the Chernobyl exclusion zone.

Debate on the Chernobyl disaster: on the causes of Chernobyl overestimation.

Science.gov (United States)

Jargin, Sergei V

2012-01-01

After the Chernobyl accident, many publications appeared that overestimated its medical consequences. Some of them are discussed in this article. Among the motives for the overestimation were anti-nuclear sentiments, widespread among some adherents of the Green movement; however, their attitude has not been wrong: nuclear facilities should have been prevented from spreading to overpopulated countries governed by unstable regimes and regions where conflicts and terrorism cannot be excluded. The Chernobyl accident has hindered worldwide development of atomic industry. Today, there are no alternatives to nuclear power: nonrenewable fossil fuels will become more and more expensive, contributing to affluence in the oil-producing countries and poverty in the rest of the world. Worldwide introduction of nuclear energy will become possible only after a concentration of authority within an efficient international executive. This will enable construction of nuclear power plants in optimally suitable places, considering all sociopolitical, geographic, geologic, and other preconditions. In this way, accidents such as that in Japan in 2011 will be prevented.

Nuclear power - the Hydra's head

Following the accident at Chernobyl, the nuclear policies of many governments have been reconsidered and restated. Those in favour of nuclear power are those with highly centralised state bureaucracies, such as France and the USSR, where public opinion is disregarded. In more democratic countries, where referenda are held, such as Austria and Sweden, the people have chosen to do away with nuclear power. Indeed, the author states that nuclear power represents the State against the people, the State against democracy. Reference is made to the IAEA Reactor Safety Conference held in September, 1986, in Vienna, and the declaration sent to it by AntiAtom International. This called for the United Nations to promote the phasing out of nuclear power facilities throughout the world. It also called on the IAEA to support the phasing out of nuclear power and promote benign energy forms instead.

Disaster policy and nuclear liability: insights from post-Chernobyl agriculture in the United Kingdom

The recent events at Chernobyl have again brought the issues of nuclear safety to the forefront of the nuclear power debate. Fortunately, our experience with such incidents has been very limited, but it is important to learn as much as possible from such events so as to minimize the cost and effect of any other nuclear incidents, be they small or large. Much of the discussion about the possible effects of nuclear incidents has centered around the human cost in terms of health. While this is undoubtedly of paramount concern, the effect of the release of radiation from Chernobyl on the agricultural resource base in Europe can provide valuable insights on how to reduce the costs associated with the contamination of agricultural areas. This article outlines some of the lessons that can be learned using the livestock-raising industry in northern Wales as an example

Chernobyl's other legacy

International Nuclear Information System (INIS)

Hohenemser, C.; Renn, O.

1988-01-01

A number of accounts of the Chernobyl accident argue that governments and the public were overwhelmed by the transnational impact of the accident, and that their response was in some sense irrational or exaggerated. This article describes the essential features of what is now known about the radiation release at Chernobyl, its world-wide dispersion, the resulting exposures, and the expected health consequences. With this basis the fallout exposure is related to changes in public attitudes about nuclear power, to the extent of protective action achieved, and to the level commitment to nuclear power in several countries. This analysis allows a number of questions to be posed, as follows: 1. Were shifts in public opinion related to the level of exposure, and if so, what does this suggest? 2. Were protective actions, as measured by radiation exposure averted (dose savings), proportional to the danger posed? 3. Were protective actions related to the change in public attitudes toward nuclear power? 4. Was a country's degree of commitment to nuclear energy, as measured by the nuclear share of electricity generation, a factor in its response to the Chernobyl accident? Analysis of these questions, which is largely based on data for the Western democracies, suggests that, with some significant exceptions, both public and government responses were surprisingly rational in that they were proportional to the public's level of exposure. This finding speaks in turn to the central importance of public information in fashioning a response to risky technology. 41 notes, 6 figures, 4 tables

Real and mythical consequences of Chernobyl accident

Osmachkin, V.S.

1999-01-01

This presentation describes the public Unacceptance of Nuclear Power as a consequence of Chernobyl Accident, an accident which was a severest event in the history of the nuclear industry. It was a shock for everybody, who has been involved in nuclear power programs. But nobody could expect that it was also the end romantic page in the nuclear story. The scale of the detriment was a great, and it could be compared with other big technological man-made catastrophes. But immediately after an accident mass media and news agencies started to transmit an information with a great exaggerations of the consequences of the event. In a report on the Seminar T he lessons of the Chernobyl - 1' in 1996 examples of such incorrect information, were cited. Particularly, in the mass media it was declared that consequences of the accident could be compared with a results of the second world war, the number of victims were more than hundred thousand people, more than million of children have the serious health detriments. Such and other cases of the misconstruction have been called as myths. The real consequences of Chernobyl disaster have been summed on the International Conference 'One decade after Chernobyl' - 2, in April 1996. A very important result of the Chernobyl accident was a dissemination of stable unacceptance of the everything connected with 'the atom'. A mystic horror from invisible mortal radiation has been inspired in the masses. And from such public attitude the Nuclear Power Programs in many countries have changed dramatically. A new more pragmatic and more careful atomic era started with a slogan: 'Kernkraftwerk ? Nein, danke'. No doubt, a Chernobyl accident was a serious technical catastrophe in atomic industry. The scale of detriment is connected with a number of involved peoples, not with a number of real victims. In comparison with Bhopal case, earthquakes, crashes of the airplanes, floods, traffic accidents and other risky events of our life - the Chernobyl is

Public and media attitudes to nuclear power in Italy

Belelli, U.

1988-01-01

A study carried out by the Italian Electricity Board on the public acceptability of nuclear power, is reported. The question was examined in two ways. A sociological analysis was carried out with the aim of understanding the behaviour of public opinion. The results revealed that individual attitudes towards nuclear power are based on cost-benefit evaluations assessed in terms of social parameters by an instinctive rather than a rational process. Secondly press articles before and after the Chernobyl accident were analysed in terms of both the message being communicated and the quality of the technical content. Characteristics of the press coverage were more stress on nuclear safety after Chernobyl leading to greater opposition to nuclear power in general, a tendency for comment to dominate over factual information and no proper evaluation of the technical content. The major overall conclusions drawn are the need for international cooperation to address the social implications of the nuclear question, and for effective communication of information on power plant safety both to expert social and political bodies and, in a popular version, to the general public.

On Saturday 26 April 1986, an accident which was to have global repercussions occurred at Unit 4 of the Chernobyl nuclear power plant in Ukraine. The accident involved the largest short term release from a single source of radioactive materials to the atmosphere ever recorded. The debate about the consequences of the accident of Chernobyl became a real saga, probably one of the most extensive controversial history of the modern technological era. There was a general concern among the population regarding the health consequences of such releases and the safety of nuclear facilities. (author)

Radiation Exposure and Thyroid Cancer Risk After the Fukushima Nuclear Power Plant Accident in Comparison with the Chernobyl Accident

Yamashita, S.; Takamura, N.; Ohtsuru, A.; Suzuki, S.

2016-01-01

The actual implementation of the epidemiological study on human health risk from low dose and low-dose rate radiation exposure and the comprehensive long-term radiation health effects survey are important especially after radiological and nuclear accidents because of public fear and concern about the long-term health effects of low-dose radiation exposure have increased considerably. Since the Great East Japan earthquake and the Fukushima Daiichi Nuclear Power Plant accident in Japan, Fukushima Prefecture has started the Fukushima Health Management Survey Project for the purpose of long-term health care administration and medical early diagnosis/treatment for the prefectural residents. Especially on a basis of the lessons learned from the Chernobyl accident, both thyroid examination and mental health care are critically important irrespective of the level of radiation exposure. There are considerable differences between Chernobyl and Fukushima regarding radiation dose to the public, and it is very difficult to estimate retrospectively internal exposure dose from the short-lived radioactive iodines. Therefore, the necessity of thyroid ultrasound examination in Fukushima and the intermediate results of this survey targeting children will be reviewed and discussed in order to avoid any misunderstanding or misinterpretation of the high detection rate of childhood thyroid cancer.

The International Atomic Energy Agency (IAEA) introduced the concept of safety culture when analyzing the Chernobyl accident. Safety culture has now been widely accepted and practiced by nuclear enterprise in the world. As an important safeguard for nuclear safety, safety culture has become the core of nuclear power enterprise and entitled as the soul of nuclear enterprise. This paper analyzes the three levels of safety culture and describes its three developing phases. (authors)

Present state of things relating to the nuclear power generation are described first, focusing on the Chernobyl accident, power control test, old-wave and new-wave antinuclear movements, move toward elimination of nuclear power plants, and trend in government-level argument concerning nuclear power generation. Then the importance of public relations activities for nuclear power generation is emphasized. It is stressed that information should be supplied positively to the public to obtain public understanding and confidence. Various activities currently made to promote public relations for nuclear power generation are also outlined, focusing on the improvement in the nuclear power public relations system and practical plans for these activities. Activities for improvement in the public relations system include the organization of public relations groups, establishment and effective implementation of an overall public relations plan, training of core workers for public relations, and management of the public relations system. Other practical activities include the encouragement of the public to come and see the power generation facilities and distribution of pamphlets, and use of the media. (N.K.)

Chernobyl: the Long Shadow offers a balanced review of what happened there, why and how it happened, and what the main lessons and implications of the accident are. It looks back on events during and after the disaster, in particular reviewing how it and the radiation fallout were dealt with in different countries, and looks forward to how the incident might affect the nuclear power industry around the world. The book explores the significance of the accident within the Soviet Union, considers its impact on public confidence in nuclear power, and reviews what improvements are necessary in emergency planning throughout the rest of the world. It is written from an inter-disciplinary perspective; based on detailed scientific research, which is described in non-specialist terms, it considers themes like attitudes to nuclear power and political reactions to the accident itself. It sets the Chernobyl accident into a proper context, and will appeal to students and teachers of geography, environmental science, international politics, nuclear physics, and to anyone interested in current affairs and environmental problems.

Following the accident at the Soviet nuclear power station at Chernobyl in April 1986, the CEGB produced this video which has now been updated in the light of the information provided by the Soviets at the International Atomic Energy Agency Conference in Vienna. At this conference it was made clear that the Chernobyl accident would have been impossible in any nuclear reactor operational outside the USSR. This video explains why. It examines the main reasons for the failure of the reactor at Chernobyl and the two fundamental design flaws which resulted in the sequence of events leading up to the accident. It shows how British reactors have built-in protection to compensate for failure in any part of the system, and how the reactors are tolerant to operator error. The programme also explains the safety standards and regulations which are enforced in CEGB nuclear power stations and the rigorous training that reactor operators have to undergo.

The article summarizes the current controversial discussions in the public about the utilisation of nuclear energy in the F.R.G., which has gained so much emotional impetus after the Chernobyl reactor accident. The accident scenario and the causes of the disaster are outlined in order to show the difference between facts and conditions there, and design and conditions in our country, especially with regard to the LWRs. The main reason launching the disaster, it is said, lies in non-observance of orders and operating instructions; the article underlines the system of design features and instructions that has been established, and multiply checked, for reactor stations in the F.R.G., in order to prevent undue interference with the design-based safety equipment. Due to the high safety standard of the nuclear power plants in the F.R.G., Chernobyl cannot be used as an argument against further utilisation of nuclear energy in the F.R.G. (HSCH) [de

The Chernobyl disaster has been a terrible confirmation of all warnings and worries spoken out by anti-nuclear groups of the population. Their core statement in debates on nuclear power already before the Chernobyl accident has been: Nuclear power has reached the end of the rope, for ecological reasons and for reasons of energy policy. This argument is now shown to be true by the analyses and research results presented by the book. Nuclear hazards will remain non-managable, and there is enough reason to doubt the economic efficiency of nuclear electricity. Nuclear power subsists by the sheer political and economic power of the nuclear lobby. The book in hand is the third revised and enlarged edition, presenting topical information on the Chernobyl MCA collected by scientists and journalists who are engaged in the anti-nuclear movement. Basic and exciting facts are given of topics such as: Worldwide crisis of the nuclear industry; history of the German nuclear power programme; the power of the electric utilities; Harrisburg and the latest safety studies; hazards of 'normal operation'; the big risk of the Wackersdorf plant and the illusion of 'ultimate disposal'.

This book evolves a number of theses on these questions dealing above all with the determinants of political protest. Two investigations are presented in order to verify those theses: in 1982 and 1987 (some nine months after the Chernobyl reactor accident), the same persons were interviewed. In addition, representative surveys in the Federal Republic of Germany are analysed, in order to assess in general the impact of Chernobyl. From the contents: explanation model for political protest; Chernobyl effect: effect of critical events on the mobilization of political protest; discontent with nuclear energy use, political alienation and protest; internal incentives for protest: norms, readiness for aggression, and entertainment quality of protest; resources as determinants of political protest; sanctions and protest; social nets and political protest; verification of a central model of political protest, and problems encountered by research.

Fukushima Nuclear Accident, the Third International Severe Nuclear Power Plant Accident

Japan is the world's third largest power user. Japan's last remaining nuclear reactor shutdown on Saturday 4 Th of May 2012 leaving the country entirely nuclear free. All of 50 of the nation's operable reactors (not counting for the four crippled reactors at Fukushima) are now offline. Before last year's Fukushima nuclear disaster, the country obtained 30% of its energy from nuclear plants, and had planned to produce up to 50% of its power from nuclear sources by 2030. Japan declared states of emergency for five nuclear reactors at two power plants after the units lost cooling ability in the aftermath of Friday 11 March 2011 powerful earthquake. Thousands of (14000) residents were immediately evacuated as workers struggled to get the reactors under control to prevent meltdowns. On March 11 Th, 2011, Japan experienced a sever earthquake resulting in the shutdown of multiple reactors. At Fukushima Daiichi site, the earthquake caused the loss of normal Ac power. In addition it appeals that the ensuing tsunami caused the loss of emergency Ac power at the site. Subsequent events caused damage to fuel and radiological releases offsite. The spent fuel problem is a wild card in the potentially catastrophic failure of Fukushima power plant. Since the Friday's 9.0 earthquake, the plant has been wracked by repeated explosions in three different reactors. Nuclear experts emphasized there are significant differences between the unfolding nuclear crisis at Fukushima and the events leading up to the Chernobyl disaster in 1986. The Chernobyl reactor exploded during a power surge while it was in operation and released a major cloud of radiation because the reactor had no containment structure around to. At Fukushima, each reactor has shutdown and is inside a 20 cm-thick steel pressure vessel that is designed to contain a meltdown. The pressure vessels themselves are surrounded by steel-lined, reinforced concrete shells. Chernobyl disaster was classified 7 on the International

Efforts to integrate the Washington meetings of the American Nuclear Society and the Atomic Industrial Forum included joint plenary sessions and combined criticism of DOE actions regarding the selection of a second repository for radioactive wastes. The meetings also looked beyond the Chernobyl accident to point out that some countries can no longer reject nuclear power, but the industry must develop post-accident plans for plants in order to reduce risks. Speakers warned against over-reacting and the need to keep emergency planning flexible. Other speakers concluded that the Chernobyl design was not so much at fault as the decision to build larger versions of the standardized design. The pursuit of excellence in plant design and performance, the need to resolve regulatory problems involving the inclusion of nuclear plants in utility rate bases, and the economics of low-level waste disposal, were other topics covered

The world's most severe nuclear accident destroyed the fourth unit at the Chernobyl nuclear power plant in 1986. In the six months following the accident, a localizing building was erected over the unit to contain the nuclear materials and provide support services for managing the destroyed reactor. Since 1997, an international project which includes both urgent measures for stabilization and safety upgrading as well as long-term measures for transforming the facility into an ecologically safe system has been under way. This paper discusses an important aspect of this project which has been the cooperation amongst the technical support organizations of the Ukrainian regulatory authorities and the technical support from international organizations.

Oil and nuclear power: the dynamic interrelationship

International Nuclear Information System (INIS)

Stauffer, T.

1987-01-01

The impact of changing oil prices on the economic case for nuclear power and the political viability of the nuclear industry is reviewed. The case for nuclear energy is less obvious currently on the grounds of safety (following the Chernobyl accident), need (because of slower economic growth and energy conservation) and rationale (the cost advantage is no longer obvious). Nuclear power and oil prices are shown to be interrelated because the competitive economics of each is affected by the other. The competitive balance between the two changes. The use of nuclear power helps to keep oil prices down. However, if oil is cheap, nuclear power is less favourable economically. Some facts and figures are used to illustrate this paradox. (U.K.)

Chernobyl - once the name of an obscure Soviet nuclear plant in the Ukraine - has become a global household word because of the April 1986 explosion that destroyed one of its reactors and spread radioactive fallout over most of the northern hemisphere. A September 1986 study from the Lawrence Livermore Laboratory revealed that this disaster released as much radioactivity into the soil, air, and water as all the nuclear tests and bombs exploded since the 1940s. In this book by a team of correspondents from the London Observer, all the essential information is given: a description of Chernobyl town and its nuclear plant; a vivid account of the events surrounding the accident, in which many people acted heroically; the delays in reporting the disaster; the problems of evacuating people and of coping with the injured; the reactions in the Soviet Union and around the world; and the immediate and possible longterm effects of the release of so much radioactivity

This paper reports that since the Chernobyl nuclear plant accident in 1986, over 70 of the International Atomic Energy Agency's 112 member states have adopted two conventions to enhance international cooperation by providing timely notification of an accident and emergency assistance. The Agency and other international organizations also developed programs to improve nuclear power plant safety and minimize dangers from radioactive contamination. Despite meaningful improvements, some of the measures have limitations, and serious nuclear safety problems remain in the design and operation of the older, Soviet-designed nuclear power plants. The Agency's ability to select reactors under its operational safety review program is limited. Also, information on the extent and seriousness of safety-related incidents at reactors in foreign countries is not publicly available. No agreements exist among nuclear power countries to make compliance with an nuclear safety standards or principles mandatory. Currently, adherence to international safety standards or principles is voluntary and nonbinding. Some states support the concept of mandatory compliance, but others, including the United States, believe that mandatory compliance infringes on national sovereignty and that the responsibility for nuclear reactor safety remains with each nation

Implications of the accident at Chernobyl for safety regulation of commercial nuclear power plants in the United States: Volume 1, Main report: Final report

International Nuclear Information System (INIS)

1989-04-01

This report was prepared by the Nuclear Regulatory Commission (NRC) staff to assess the implications of the accident at the Chernobyl nuclear power plant as they relate to reactor safety regulation for commercial nuclear power plants in the United States. The facts used in this assessment have been drawn from the US fact-finding report (NUREG-1250) and its sources. The general conclusions of the document are that there are generic lessons to be learned but that no changes in regulations are needed due to the substantial differences in the design, safety features and operation of US plants as compared to those in the USSR. Given these general conclusions, further consideration of certain specific areas is recommended by the report. These include: administrative controls over reactor regulation, reactivity accidents, accidents at low or zero power, multi-unit protection, fires, containment, emergency planning, severe accident phenomena, and graphite-moderated reactors

[Aspects of aetiology of neuro-psychic disorders in male liquidators of Chernobyl nuclear power accident consequences].

Science.gov (United States)

Skavysh, V A

2009-01-01

The author considered aetiology of neuro-psychic disorders in liquidators of Chernobyl nuclear power accident consequences, demonstrated scientific value of studying the liquidators cohort, as they were protected from internal radiation factors and reside on radiation "pure" territories. External radiation doses in those liquidators vary from 16 cGy to 18.7 +/- 10.8 cGy, according to the author. Catamnesis enabled to doubt radiation aetiology of psychic organic syndrome revealed in 1991-1994 by clinical and instrumental studies among 53.6% of 213 male examinees. According to the author, prolonged over 1-2 months external radiation of low dose could not cause health deterioration in adult males. Diagnosed psychic organic syndrome and vascular encephalopathy in some cases could have alcohol aetiology. This conclusion is not extrapolated to the whole liquidators cohort.

Environmental hazards and nuclear power phaseout

The paper analyses the radiation exposure of the population during normal operation and in the wake of accidents at nuclear power plants, and discusses hypothetic accidents. It also judges the additional radiation exposure of the population from nuclear energy, investigates forest decline and radioactivity, as well as radioactive waste disposal and underground storage. In the upshot, nuclear power after and in spite of Chernobyl still remains an important option and an ecologically reasonable possibility for safeguarding the fundamental needs of the five billion people now living, and those further billions to be added in the decades to come.

Radiation Exposure and Thyroid Cancer Risk After the Fukushima Nuclear Power Plant Accident in Comparison with the Chernobyl Accident.

Science.gov (United States)

Yamashita, S; Takamura, N; Ohtsuru, A; Suzuki, S

2016-09-01

The actual implementation of the epidemiological study on human health risk from low dose and low-dose rate radiation exposure and the comprehensive long-term radiation health effects survey are important especially after radiological and nuclear accidents because of public fear and concern about the long-term health effects of low-dose radiation exposure have increased considerably. Since the Great East Japan earthquake and the Fukushima Daiichi Nuclear Power Plant accident in Japan, Fukushima Prefecture has started the Fukushima Health Management Survey Project for the purpose of long-term health care administration and medical early diagnosis/treatment for the prefectural residents. Especially on a basis of the lessons learned from the Chernobyl accident, both thyroid examination and mental health care are critically important irrespective of the level of radiation exposure. There are considerable differences between Chernobyl and Fukushima regarding radiation dose to the public, and it is very difficult to estimate retrospectively internal exposure dose from the short-lived radioactive iodines. Therefore, the necessity of thyroid ultrasound examination in Fukushima and the intermediate results of this survey targeting children will be reviewed and discussed in order to avoid any misunderstanding or misinterpretation of the high detection rate of childhood thyroid cancer. © World Health Organisation 2016.

Full Text Available In the article the peculiarities of ideas about the catastrophe at the Chernobyl nuclear power plant disaster at the persons who have suffered from radiation during liquidation of the accident’s consequences. View of the accident was considered as a key element of a person’s mind, in particular the adaptive. There were 30 persons, who took part in the research – participants of Chernobyl disaster’s liquidation, veterans of division of an extra risk. The subjective assessment of mental health at persons who survived in Chernobyl disaster was defined; personal properties of victims were revealed; interrelations between personal properties and subjective assessment of mental health were established. It is possible to assume that in process of moving away from the moment of the accident the content of view of Chernobyl disaster shows concentration of the person on experience of mental health and the personal potential.

Ten years ago, on April 26, 1986 the most serious accident ever in the history of nuclear tgechnology worldwide happened in unit 4 of the nuclear power plant in Chernobyl in the Ukraine, this accident unveiling to the world at large that the Soviet reactor design lines are bearing unthought of safety engineering deficits. The dimensions of this reactor accident on site, and the radioactive fallout spreading far and wide to many countries in Europe, vividly nourished the concern of great parts of the population in the Western world about the safety of nuclear technology, and re-instigated debates about the risks involved and their justification. Now that ten years have elapsed since the accident, it is appropriate to strike a balance and analyse the situation today. The number of nuclear power plants operating worldwide has been growing in the last few years and this trend will continue, primarily due to developments in Asia. The Chernobyl reactor accident has pushed the international dimension of reactor safety to the foreground. Thus the Western world had reason enough to commit itself to enhancing the engineered safety of reactors in East Europe. The article analyses some of the major developments and activities to date and shows future perspectives. (orig.) [de

The Chernobyl Nuclear Power Plant (CNPP) accident occurred on April 26 of 1986, it is still an episode of interest, due to the large amount of radionuclides dispersed in the atmosphere. Caesium-137 ({sup 137}Cs) is one of the main radionuclides emitted during the Chernobyl accident, with a half-life of 30 years, which can be accumulated in humans and animals, and for this reason the impacts on population are still monitored today. One of the main parameters in order to estimate the exposure of population to {sup 137}Cs is the concentration in the air, during the days after the accident, and the deposition at surface. The transport and deposition of {sup 137}Cs over Europe occurred after the CNPP accident has been simulated using the WRF-HYSPLIT modeling system. Four different vertical and temporal emission rate profiles have been simulated, as well as two different dry deposition velocities. The model simulations could reproduce fairly well the observations of {sup 137}Cs concentrations and deposition, which were used to generate the ‘Atlas of Caesium deposition on Europe after the Chernobyl accident’ and published in 1998. An additional focus was given on {sup 137}Cs deposition and air concentrations over Turkey, which was one of the main affected countries, but not included in the results of the Atlas. We estimated a total deposition of 2–3.5 PBq over Turkey, with 2 main regions affected, East Turkey and Central Black Sea coast until Central Anatolia, with values between 10 kBq m{sup −2} and 100 kBq m{sup −2}. Mean radiological effective doses from simulated air concentrations and deposition has been estimated for Turkey reaching 0.15 mSv/year in the North Eastern part of Turkey, even if the contribution from ingestion of contaminated food and water is not considered, the estimated levels are largely below the 1 mSv limit indicated by the International Commission on Radiological Protection. - Highlights: • Chernobyl Nuclear Power Plant accident

27 June 1954 saw the birth of nuclear power in the Soviet Union when a 5 MWe plant went into operation. The second reference point falls on 26 April 1986. Since then the fate of nuclear energy in the Soviet Union has been transformed once again: ft is now clear the Chernobyl did not entirely bury the notion of building nuclear p0wer stations. There are even signs that the leaders of the new states, as well as the general public, are beginning to see some of benefits of continuing with nuclear power programmes

Nuclear power and the private sector

International Nuclear Information System (INIS)

Miller, D.J.

1989-01-01

The world scene is sketched in which nuclear power already contributes 600 Mtce/year to world energy but where public attitudes in the developed world have become largely hostile. This is despite the proven technology of nuclear power, its safety record (Chernobyl notwithstanding) and its environmentally benign aspects. The United Kingdom government's determination to ensure a continuing role for nuclear power in a privatized electricity supply industry is seen against this background. The structure of the British nuclear power industry undoubtedly presents difficulties for privatization but solutions are available and precedents for private sector nuclear power exist in other countries. Private sector operators will be required to meet the exacting standards set by the independent licensing authority but in view of the public concern redoubled efforts and new approaches will be necessary in public persuasion. Waste disposal is another issue which may have implications for the acceptability of nuclear power in the public sector. Finally, the prospects for investment in new nuclear plant by private generation companies are examined. (U.K.)

10th anniversary of Chernobyl

International Nuclear Information System (INIS)

Hayes, Roger

1995-01-01

Every issue has its defining event. There is no doubt that the single word which now embodies that difficult-to express unease felt by many people about nuclear power is Chernobyl. In this sense, April 26 1996 will be far more than an anniversary, just as Chernobyl was far more than a very serious accident which was nonetheless largely localised in its effects. It will be used by those who wish to the industry - the professional campaigners in the Green movement - and those who see an opportunity to sell newspapers or TV programmes - the professional exaggerators - to spread that unease as far as possible. The British Nuclear Industry Forum, which consists of seventy member companies at the heart of nuclear power in the UK, has convened a Task Force, with an international membership, in an attempt to make sure that we are ready for the anniversary, and to respond to the tactics of the opposition in as effective a way as possible. This paper outlines the general principles which have so far emerged from our discussions. There are two guiding principles to our approach. The first is that no matter how good a story is about Chernobyl, it is still a bad story. But secondly, this anniversary will be big news whether we like it or not, so we must make the best of it. In this sense the event brings with it opportunities to remind people of positive messages, on fuel diversity, on environment, and on Western efforts to help to improve the safety standards of the nuclear industry in the region, and the health of the people near Chernobyl. This leads to a position for the campaign which might appear paradoxical. We must be proactive but low-profile. We simply cannot afford to keep quiet and let the wildest claims about the effects of Chernobyl be spouted unchallenged. This does not simply mean generating responses to stories once they have been published. It means analysing press coverage of previous anniversaries to understand how the media are likely to treat it; it means

Response to the Chernobyl accident in Japan

The worst nuclear accident in history happened at No.4 unit of the Chernobyl Atomic Power Station in USSR. Since the Chernobyl accident, a number of measures have been introduced in many countries, including the reconsideration of programs for construction and operation of nuclear power plants. In Japan, the press and television first reported the accident on April 29. The next day, all the relevant governmental agencies began to collect and analyze information in order to prepare possible countermeasures. The Nuclear Safety Commission issued a statement covering three points: 1) the radioactive substances released by the accident will have virtually no influence on the health of people in Japan, 2) a Special Committee on the Chernobyl Atomic Power Station Accident will be established, and 3) the Soviet government must provide all detailed information about the accident as soon as it is available. On April 30, the Committee on Radioactivity decided to increase radioactivity observations by the Science and Technology Agency, the Defence Agency, and the Meteorological Agency. On the same day, the Ministry of International Trade and Industry set up a survey committee for the Chernobyl accident with the responsibility of collecting and analyzing information about the accident. A review is also made in this article as to how the Japanese media reported the accident and how people reacted on reading the newspapers and watching TV on the accident. (Nogami, K.)

On April 26, 1986, the Unit 4 of the RBMK nuclear power plant of Chernobyl, in Ukraine, went out of control during a test at low-power, leading to an explosion and fire. The reactor building was totally demolished and very large amounts of radiation were released into the atmosphere for several hundred kilometres around the site including the nearby town of Pripyat. The explosion leaving tons of nuclear waste and spent fuel residues without any protection and control totally contaminating the entire area. Several hundred thousand people were affected by the radiation fall out. The radioactive cloud spread across Europe affecting most of the Northern, Central and Eastern European countries. Some areas of southern Switzerland, of northern Italy as well as western France were subject to radioactive contamination. The initiative of the G7 countries to launch and important programme for the closure of some Soviet built nuclear plants was accepted by several donor countries. A team of engineers was established wi...

Comparison of the Chernobyl and Fukushima nuclear accidents: A review of the environmental impacts

Steinhauser, Georg, E-mail: georg.steinhauser@colostate.edu; Brandl, Alexander; Johnson, Thomas E.

2014-02-01

The environmental impacts of the nuclear accidents of Chernobyl and Fukushima are compared. In almost every respect, the consequences of the Chernobyl accident clearly exceeded those of the Fukushima accident. In both accidents, most of the radioactivity released was due to volatile radionuclides (noble gases, iodine, cesium, tellurium). However, the amount of refractory elements (including actinides) emitted in the course of the Chernobyl accident was approximately four orders of magnitude higher than during the Fukushima accident. For Chernobyl, a total release of 5300 PBq (excluding noble gases) has been established as the most cited source term. For Fukushima, we estimated a total source term of 520 (340–800) PBq. In the course of the Fukushima accident, the majority of the radionuclides (more than 80%) was transported offshore and deposited in the Pacific Ocean. Monitoring campaigns after both accidents reveal that the environmental impact of the Chernobyl accident was much greater than of the Fukushima accident. Both the highly contaminated areas and the evacuated areas are smaller around Fukushima and the projected health effects in Japan are significantly lower than after the Chernobyl accident. This is mainly due to the fact that food safety campaigns and evacuations worked quickly and efficiently after the Fukushima accident. In contrast to Chernobyl, no fatalities due to acute radiation effects occurred in Fukushima. - Highlights: • The environmental effects of Chernobyl and Fukushima are compared. • Releases of radionuclides from Chernobyl exceeded Fukushima by an order of magnitude. • Chernobyl caused more severe radiation-related health effects. • Overall, Chernobyl was a much more severe nuclear accident than Fukushima. • Psychological effects are neglected but important consequences of nuclear accidents.

Why Russia still wants nuclear power

International Nuclear Information System (INIS)

Perera, J.

1993-01-01

Despite a recent explosion at the Tomsk uranium reprocessing plant in Siberia, and the aftermath of the Chernobyl accident, support for nuclear power is still firm in Russia. The Russian nuclear industry employs around two million people and their employment security is one of the chief factors in support of the nuclear power industry despite its safety record. The other major reason is energy shortages. Despite huge natural deposits of petroleum and gas, electric power shortages are widespread. Eighty per cent of Russia's electric power comes from oil-fired power stations, but oil supplies are unreliable. Production is dropping and, at the same time, an increasing proportion of the oil produced is exported to earn foreign currency. The concerns of environmental groups may have to be shelved, until Russia's infrastructure is efficient enough to maintain power supplies reliably. (UK)

Nuclear power in Italy

As is known to most of this audience in November of 1987 a referendum determined a rejection of nuclear power in Italy. The referendum may be taken into consideration here as a large scale experiment which offers points of interest to this conference and problems to be aware of, in approaching a severe confrontation with the public. To give a synopsis of the Italian perspective I will examine: first the public acceptance in the situation before Chernobyl, then the most disturbing and sensitive factors of Chernobyl's consequences; how the opposition to nuclear energy worked with the support of most media and the strong pressures of an anti-nuclear political party, the syllogism of the opponents and the arguments used, the causes of major weakness of the defenders and how a new perception of nuclear risk was generated in the public. I will come to the topic of utility acceptance by mentioning that ENEL, as the National Utility, in its role is bound to a policy of compliance with Government decisions. It is oriented today to performance of feasibility studies and development of requirements for the next generation of reactors in order to maintain an updated proposal for a future recovery of the nuclear option. I will then try to identify in general terms the factors determining the future acceptance of nuclear power. They will be determined in the interdisciplinary area of politics, media and public interactions with the utilities the uses of the technology are forced to follow, by political constraints, two main directives: working only in new projects to achieve, if possible, new safety goals

The Chernobyl disaster in 1986 involved the largest airborne release of radioactivity in history, more than 100 times as much radioactivity as the Hiroshima and Nagasaki atomic bombs together. The resulting emergency response, administrative blunders, and subsequent patient outcomes from this large-scale radiological disaster provide a wealth of information and valuable lessons for those who may find themselves having to deal with the staggering consequences of nuclear war. Research findings, administrative strategies (successful and otherwise), and resulting clinical procedures from the Chernobyl experience are reviewed to determine a current utility in addressing the appropriate protocols for a medical response to nuclear war. As various myths are still widely associated with radiation exposure, attention is given to the realities of a mass casualty medical response as it would occur with a nuclear detonation.

The operational safety of nuclear power plants has become an important safety issue since the Chernobyl accident. A description is given of the various aspects of operational safety, including the importance of human factors, responsibility, the role and training of the operator, the operator-machine interface, commissioning and operating procedures, experience feedback, and maintenance. The lessons to be learnt from Chernobyl are considered with respect to operator errors and the management of severe accidents. Training of personnel, operating experience feedback, actions to be taken in case of severe accidents, and international cooperation in the field of operational safety, are also discussed. (U.K.)

What is nuclear power in Japan?

Science.gov (United States)

Suzuki, Toshikazu

2011-03-01

The aggressive use of such non-fossil energy as the atomic energy with high power density and energy production efficiency is an indispensable choice aiming at the low-carbon society. There is a trial calculation that the carbon dioxide emission of 40000 ton can be suppressed by nuclear power generation by one ton of uranium. The basis of nuclear research after the Second World War in Japan was established by the researchers learnt in Argonne National Laboratory. In 2010, NPPs under operation are 54 units and the total electric generating power is 48.85GW. The amount of nuclear power generation per person of the people is 0.38kW in Japan, and it is near 0.34kW of the United States. However, the TMI accident and the Chernobyl disaster should have greatly stagnated the nuclear industry of Japan although it is not more serious than the United States. A lot of Japanese unconsciously associate a nuclear accident with the atomic bomb. According to the investigation which Science and Technology Agency carried out to the specialist in 1999, ``What will be the field where talent should be emphatically sent in the future?'' the rank of nuclear technology was the lowest in 32 fields. The influence of the nuclear industry stagnation was remarkable in the education. The subject related to the atomic energy of a university existed 19 in 1985 that was the previous year of the Chernobyl disaster decreased to 7 in 2003. In such a situation, we have to rely on the atomic energy because Japan depends for 96% of energy resources on import. The development of the fuel reprocessing and the fast breeder reactor has been continued in spite of a heavy failure. That is the only means left behind for Japan to be released from both fossil fuel and carbon dioxide.

Prospects of nuclear power in the USSR after the Chernobyl accident

Ponomarev-Stepnoj, N.; Asmolov, V.

1993-01-01

Nuclear power is an integral part of the USSR power industry. At present, about 12% of the country's electricity is produced by nuclear power plants, saving about 70 million tons per year of equivalent fossil fuel. The FEC analysis reveals that any acceptable solution of the energy supply problem and limitation hazardous ecological effects cannot be achieved without appropriate development of nuclear energy capacities, with the necessary safety levels ensured. The thorough comparative analysis of nuclear power development in the USSR, taking into account the economic factors and ecological consequences of power development shows that nuclear power capacity has to be systematically increased - up to 56 million kW by the year 2000, and 95-150 million kW by 2010. The main condition for this expansion is the enhanced nuclear power safety. This development has to be competitive with the ecologically acceptable coal power plants operating in the european part of the country. (authors)

Nuclear power safety

1988-01-01

The International Atomic Energy Agency, the organization concerned with worldwide nuclear safety has produced two international conventions to provide (1) prompt notification of nuclear accidents and (2) procedures to facilitate mutual assistance during an emergency. IAEA has also expanded operational safety review team missions, enhanced information exchange on operational safety events at nuclear power plants, and planned a review of its nuclear safety standards to ensure that they include the lessons learned from the Chernobyl nuclear plant accident. However, there appears to be a nearly unanimous belief among IAEA members that may attempt to impose international safety standards verified by an international inspection program would infringe on national sovereignty. Although several Western European countries have proposed establishing binding safety standards and inspections, no specific plant have been made; IAEA's member states are unlikely to adopt such standards and an inspection program

Fuel-containing materials sampled from within the Chernobyl Nuclear Power Plant (ChNPP) Unit 4 Confinement Shelter were spectroscopically studied for gamma and alpha content. Isotopic ratios for cesium, europium, plutonium, americium, and curium were identified, and the fuel burn-up in these samples was determined. A systematic deviation in the burn-up values based on the cesium isotopes in comparison with other radionuclides was observed. The studies conducted were the first ever performed to demonstrate the presence of significant quantities of 242Cm and 243Cm. It was determined that there was a systematic underestimation of activities of transuranic radionuclides in fuel samples from inside of the ChNPP Confinement Shelter, starting from 241Am (and going higher) in comparison with the theoretical calculations.

The public perception of the risks associated with nuclear power plants was profoundly influenced by the accidents at Three Mile Island and Chernobyl Power Plants which also served to exacerbate in the last decades the growing mistrust on the 'nuclear industry'. Part of the mistrust had its origin in the arrogance of nuclear spokesmen and in the secretiveness of nuclear programs. However, press agencies have an important role in shaping and upsizing the public awareness against nuclear energy. In this paper we present the results of a survey in reports of some Brazilian popular newspapers on Chernobyl consequences, as measured by the total death toll of the accident, to show the up and down dance of large numbers without any serious judgment.

The attitude to nuclear power of the major political parties in the United Kingdom is examined following the reactor accident at Chernobyl. In particular the Government policy, which is to reaffirm its commitment to nuclear energy, and that of the Labour opposition policy, which may be not to build any more nuclear power stations, are discussed. However, the Labour party policy is still open to debate and may be changed before the next general election. The Scottish and Welsh Nationalist parties and the Greens are all anti-nuclear. (U.K.)

French lessons in nuclear power

In stark contrast to the American atomic power experience is that of the French. Even the disaster at Chernobyl in 1986, which chilled nuclear programs throughout Western Europe, did not slow the pace of the nuclear program of the state-owned Electricite de France (EDF), based in Paris. Another five units are under construction and are scheduled to be connected to the French national power grid before the end of 1993. In 1989, the EDF's 58 nuclear reactors supplied 73 percent of French electrical needs, a higher percentage than any other country. In the United States, for example, only about 18 percent of electrical power is derived from the atom. Underpinning the success of nuclear energy in France is its use of standardized plant design and technology. This has been an imperative for the French nuclear power industry since 1974, when an intensive program of nuclear power plant construction began. It was then, in the aftermath of the first oil embargo, that the French government decided to reduce its dependence on imported oil by substituting atomic power sources for hydrocarbons. Other pillars supporting French nuclear success include retrofitting older plants with technological or design advances, intensive training of personnel, using robotic and computer aids to reduce downtime, controlling the entire nuclear fuel cycle, and maintaining a comprehensive public information effort about the nuclear program

Following the accident at the Chernobyl nuclear reactor power station in the USSR on April 26, 1986, the Environmental Measurements Laboratory (EML) initiated a number of research projects as follows: (1) selected sites in both the Deposition and Surface Air networks were alerted and their sampling protocols adjusted to accommodate the anticipated arrival times and activity concentrations of the Chernobyl debris; (2) a number of cooperative programs involving field work, sampling, analysis and data interpretation were set up with institutions and scientists in other countries; (3) EML's Regional Baseline Station at Chester, NJ, as well as the roof of the Laboratory in New York City, provided bases for sampling and measurements to study the radionuclide concentrations, radiation levels, physical characteristics and potential biological implications of the Chernobyl fallout on the northeastern United States; and (4) the resulting fallout from the Chernobyl accident provided an 'experiment of opportunity' in that it enabled us to study fresh fission product deposition using collection systems resurrected from the 1950's and 1960's for comparison with current state-of-the-art methodology. The 13 reports of this volume have been entered separately into the data base.

There was stated total content of radionuclide pollution, rejected to the environment in consequence of the accident at the Chernobyl nuclear power station, specifics of qualitative and quantitative change which supposes the division of post-accident period into five conventional post-accident periods. There were given the data about the levels of main fragmentation radionuclide activity in river water, atmospheric precipitation and sewage of the objects of sanitary treatment in May 1986. According to these data there were estimated the volumes of radioactive pollution rejection to the Kiev basins of water (1.56 centre dot 10 10 Ku, that is equal to 144,57 kg of radionuclides or 3,67 % of their mass in reactor) and their going into the Dnieper river. There was shown an interconnection of all season state of water basins which are near to Chernobyl nuclear power station, with specific development of radiation situation in them after the accident. There was proposed a probated variant of improvement of the traditional technology of drinking water preparation from the open water source within 1-2 post-accident periods

In the second of two linked articles on the aftermath of the Chernobyl nuclear reactor accident of 1986, the author explores the effects on local agriculture and the health of populations affected by the contamination from the fall-out, especially children. Agriculture around Chernobyl has resumed, with workers moving back from the cities to areas where radiation doses are similar to parts of Cornwall. Concern continues about the safety of milk from cows grazing contaminated grass and eating local mushrooms. The largest risk to children's health is not birth deformaties, but leukaemia, possibly in part due to iodine deficiency in their diet prior to contamination. Concern also continues about keeping power supplies going in areas heavily dependent on nuclear power. Reactor safety issues remaining operational RBMK reactors and the sarcophagus around Chernobyl-4 itself have yet to be resolved. (UK)

Nuclear power in our societies

Hiroshima, Chernobyl, Fukushima Daiichi are the well known sad milestones on the path toward a broad development of nuclear energy. They are so well known that they have blurred certainly for long in a very unfair way the positive image of nuclear energy in the public eye. The impact of the media appetite for disasters favours the fear and puts aside all the achievements of nuclear sciences like nuclear medicine for instance and all the assets of nuclear power like the quasi absence of greenhouse gas emission or its massive capacity to produce electricity or heat. The unique solution to enhance nuclear acceptance is the reduction of the fear through a better understanding of nuclear sciences by the public. (A.C.)

We compared the two worst nuclear accidents rated INES 7, which occurred at the Chernobyl and the Fukushima Daiichi Nuclear Power Plants. Although the human errors underlie both accidents, the respective causes differed. The accident at Chernobyl was caused by the experiment which resulted in increase in criticality and activity leading to a powerful steam explosion and fire that released a significant fraction of core material into the environment, while that at Fukushima Daiichi was due to the damage to the backup power and containment systems caused by the destructive tsunami waves triggered by the 2011 earthquake off the Pacific coast of Tohoku. The physical health effects of the Chernobyl accident demonstrated so far in general population around Chernobyl are thyroid diseases including cancer in those exposed to the accident in their childhood. The long-term program monitoring for at least 30 years the health conditions of all Fukushima residents will be introduced. (author)

Results of the environmental programmes monitoring radioactivity around the Finnish nuclear power stations in 1986 are reported. After the end of April the fallout nuclides from the Chernobyl accident predominated in all samples taken from the environs of the two power stations Loviisa and Olkiluoto. Radionuclides originating from the Finnish power stations were detected mainly in samples taken from the aquatic environment. The concentrations of the locally discharged nuclides were very low in comparison with the fallout nuclides and their impact on the radiation doses of the population was insignificant. Both nuclear power stations are situated in the main fallout area in Finland. The results of these large monitoring programmes give a good picture of the behaviour of the Chernobyl fallout in the specific areas in Finland

Full text of publication follows: Italy entered with enthusiasm into the production of nuclear energy for civil use at the end of 50. By 1966 - with an overall output of 3.9 billions kWh - Italy had become the fourth world producer of electricity generated by nuclear reactions, the second one in Europe after Great Britain. Chernobyl's 1986 disaster, which so much shook public opinion all over Europe, had particularly important economic and political consequences in Italy. In a controversial referendum, held in November 1987, Italian citizens voted for the repeal of three laws which promoted the installation of nuclear power plants on the Italian soil and the participation of ENEL (National Institution for the Electrical Energy) to plant constructions abroad. The 1987 referendum was interpreted by the Italian government as an opposition to nuclear power generation - the following year, the four Italian plants (Garigliano, Latina, Trino Vercellese, Caorso) ceased their activity and plans to build new plants were abandoned. This decision marked the ruin of Italian research on nuclear energy, that in the 30 had known a glorious era thanks to Enrico Fermi works. As the 20. Anniversary of Chernobyl's accident is drawing near, the University of Milan and ICS-research group (Innovations in Communication of Science) at SISSA, Trieste, have decided to analyse jointly the reasons which brought Italy to give up its nuclear energy production. In the present scenario of controversies concerning the development of science and technology, in which European countries exchange experiences of best practice to involve the public in decision making processes, Italy reaction to Chernobyl accident can indeed be considered paradigmatic in that it anticipated crucial risks governance issues in today relationship between science and society. The research project draws on methodologies used in media studies and on socio linguistic analysis, as developed by risk perception and risk

The Chernobyl disaster has intensified the whole debate on the nuclear power industry. There is currently great public concern about the way the industry is regulated, about the siting of nuclear facilities, including the dumping of nuclear waste, and about the alleged secretiveness of the industry. This book examines these and many other important aspects of the industry worldwide and provides much important original research. It focuses in particular on the political processes which control the industry, on waste disposal and on the social impact

It has been 30 years since the worst accident in the history of the nuclear era occurred at the Chernobyl power plant in Ukraine close to densely populated urban areas. To date, epidemiological studies reported increased long-term risks of leukemia, cardiovascular diseases, and cataracts among cleanup workers and of thyroid cancer and non-malignant diseases in those exposed as children and adolescents. Mental health effects were the most significant public health consequence of the accident in the three most contaminated countries of Ukraine, Belarus, and the Russian Federation. Timely and clear communication with affected populations emerged as one of the main lessons in the aftermath of the Chernobyl nuclear accident.

Nuclear power's burdened future

Flavin, C.

Although governments of the world's leading nations are reiterating their faith in nuclear power, Chernobyl has brought into focus the public's overwhelming feeling that the current generation of nuclear technology is simple not working. Despite the drastic slowdown, however, the global nuclear enterprise is large. As of mid-1986, the world had 366 nuclear power plants in operation, with a generating capacity of 255,670 MW. These facilities generate about 15% of the world's electricity, ranging from 65% in France to 31% in West Germany, 23% in Japan, 16% in the United States, 10% in the Soviet Union, and non in most developing nations. Nuclear development is clearly dominated by the most economically powerful and technologically advanced nations. The United States, France, the Soviet Union, Japan, and West Germany has 72% of the world's generating capacity and set the international nuclear pace. The reasons for scaling back nuclear programs are almost as diverse as the countries themselves. High costs, slowing electricity demand growth, technical problems, mismanagement, and political opposition have all had an effect. Yet these various factors actually form a complex web of inter-related problems. For example, rising costs usually represent some combination of technical problems and mismanagement, and political opposition often occurs because of safety concerns or rising costs. 13 references

On April 26, 1986, an accident at the fourth power unit of the Chernobyl NPS (ChNPS) destroyed the reactor core and part of the power unit building, whereby sizeable amounts of radioactive materials, stored in reactor at operation, were released into the environment, and there were also highly active fragments of fuel elements and pieces of graphite from reactor spread on ChNPS site near to safety block. Information on the accident at ChNPS, including its cause and consequences, was considered at special meeting, conducted by IAEA on August 25-29, 1986, in Vienna. In final report of International Advisory Group for Nuclear Safety (IAGNS), prepared by results of meeting activities, the main stages of the accident effects elimination (AEE) immediately on the station site according to the data, received before August 1, 1986, were discussed. In 1987-1990 the published materials on the later period of AEE, completed by building ''Ukrytie'' installation at the fourth power unit of ChNPS

Chernobyl reactor transient simulation study

Gaber, F.A.; El Messiry, A.M.

This paper deals with the Chernobyl nuclear power station transient simulation study. The Chernobyl (RBMK) reactor is a graphite moderated pressure tube type reactor. It is cooled by circulating light water that boils in the upper parts of vertical pressure tubes to produce steam. At equilibrium fuel irradiation, the RBMK reactor has a positive void reactivity coefficient. However, the fuel temperature coefficient is negative and the net effect of a power change depends upon the power level. Under normal operating conditions the net effect (power coefficient) is negative at full power and becomes positive under certain transient conditions. A series of dynamic performance transient analysis for RBMK reactor, pressurized water reactor (PWR) and fast breeder reactor (FBR) have been performed using digital simulator codes, the purpose of this transient study is to show that an accident of Chernobyl's severity does not occur in PWR or FBR nuclear power reactors. This appears from the study of the inherent, stability of RBMK, PWR and FBR under certain transient conditions. This inherent stability is related to the effect of the feed back reactivity. The power distribution stability in the graphite RBMK reactor is difficult to maintain throughout its entire life, so the reactor has an inherent instability. PWR has larger negative temperature coefficient of reactivity, therefore, the PWR by itself has a large amount of natural stability, so PWR is inherently safe. FBR has positive sodium expansion coefficient, therefore it has insufficient stability it has been concluded that PWR has safe operation than FBR and RBMK reactors

Nuclear power and health. The implications for health of nuclear power production

International Nuclear Information System (INIS)

1994-01-01

Nuclear power production is, in principle, a safe technology when practised in accordance with the well established and very strict national and international rules and regulations. Yet management failures have occurred, resulting in injuries to personnel and, occasionally, escape of radioactive material. Such events may cause potential health problems, affecting physical, mental and social well-being. Public concern still tends to concentrate on nuclear-power-related facilities, yet the public's desire for a reduction in environmental pollution has led to increased demand for the development and use of low-waste or non-waste energy technologies. Nuclear energy production is one such technology, which has become established and well developed, particularly in highly industrialized countries. This was recognized by the WHO Regional Office for Europe as early as the 1970s, and led to a series of scientific working groups to discuss the most urgent issues related to the impact on health of the generation of electrical power by means of nuclear energy. Five major meetings took place between 1975 and 1985, resulting in five publications (1 - 5) covering various aspects of particular concern to the general public (and thus also to national authorities) such as handling plutonium, managing high-level radioactive waste, and preparing for accidental releases of radioactive material. The first such publication was issued in 1977. All five books were based on the collective knowledge and experience of groups of experts, and were published following the meetings of the respective working groups. The project was initiated at the request and with the support of the Government of Belgium, to study and discuss the effects of the nuclear power industry on people and the environment. The project served two objectives. First, it assisted Member States in developing the capacity to understand the public health implications of the widespread use of nuclear power. Second, it

The April 1986 Chernobyl Nuclear Power Plant accident caused ecological changes in the Ovruch State forests in the Zhytomir oblast in the Ukraine. The highest radioactivity existed in moss, followed by the pine-forest substrate and soil. During 1984-1985, the pine needles were primarily surface contaminated, whereas during 1986-1988, they were contaminated secondarily. Radioactivity in air was highest (1.07+/-0.185 Bq/l) during dry and sunny weather and when trees were felled; the lowest levels (0.196+/-0.044 Bq/l) occurred during periods of stable snow coverage. Between 1987 and 1989 (i.e., after the Chernobyl accident), the caesium levels in forestry employees exceeded by 13.9-fold the average levels found in the Ukrainian Polessje population. Ovruch forest guards and woodcutters had the highest effective equivalent doses of radiation, and they therefore exhibited the highest carcinogenic risk.

The disaster in Unit 4 of the nuclear power plant of Chernobyl, now Ukraine, occurred fourteen years ago. Although much has been written about the accident, the public still has no proper yardstick by which to assess realistically the risk involved. This is true not only with respect to nuclear power plants of the type found in Germany and almost anywhere in the western world, but also in relation to non-nuclear disasters, which tend to be accepted by the public much more readily. As far as the number of persons killed or injured is concerned, the scope of the Chernobyl disaster turned out to be smaller than, or at least comparable to, other disasters. This is true even in comparison with other power generation technologies, for instance, accidents in coal mining or dam bursts. Even major railway accidents, airplane crashes, or the large number of people regularly killed in road traffic, are soon forgotten by the media. (orig.) [de

The lessons learned from the Chernobyl disaster have become increasingly important after the second anniversary of the Fukushima, Japan nuclear accident. Historically, data from the Chernobyl reactor accident 27 years ago demonstrated a strong correlation with thyroid cancer, but data on the radiation effects of Chernobyl on breast cancer incidence have remained inconclusive. We reviewed the published literature on the effects of the Chernobyl disaster on breast cancer incidence, using Medline and Scopus from the time of the accident to December of 2010. Our findings indicate limited data and statistical flaws. Other confounding factors, such as discrepancies in data collection, make interpretation of the results from the published literature difficult. Re-analyzing the data reveals that the incidence of breast cancer in Chernobyl-disaster-exposed women could be higher than previously thought. We have learned little of the consequences of radiation exposure at Chernobyl except for its effects on thyroid cancer incidence. Marking the 27th year after the Chernobyl event, this report sheds light on a specific, crucial and understudied aspect of the results of radiation from a gruesome nuclear power plant disaster.

The Chernobyl reactor accident was just the last but not the only occasion that threw out the question of whether nuclear power generation has reached its peak, or probably already is on the decline, or whether there will be new chances for nuclear energy on the power market. The answer to these questions depends on a variety of factors, among which the development of demand for energy, and especially electrical energy, certainly is the decisive factor. The summarizing statements published in the proceedings in hand have been written in January 1986, i.e. before the Chernobyl reactor accident; but they still are relevant, as the long-term problems of energy policy persist, and nuclear energy has to tackle the same problems as before.

To understand the current situation of internal radiation exposure in the population around the Chernobyl Nuclear Power Plant (CNPP), we examined the 137 Cs body burden in six residents of Belarus, Ukraine and Russia in 2002 and 2004 using the whole-body counter (WBC) at Nagasaki Univ. (Japan). The data were compared with those of our previous study performed in 1993-1994 using the same method. In 2002 and 2004, peaks of 137 Cs were detected in two residents from Gomel, which was heavily contaminated by the CNPP accident, one from Minsk (Belarus) and one from Kiev (Ukraine), but another resident from Minsk showed no 137 Cs peaks. The results of the present study suggests that residents around the CNPP are still exposed to chronic 137 Cs internal irradiation, probably due to the daily consumption of contaminated domestic foods, but the risk of any disease by the irradiation is quite low. Long-term follow-up of WBC around the CNPP is useful and may contribute to radiation safety regulation together with a reduction of unnecessary radio-phobia for the residents. (authors)

The 1986 Challenger accident coupled with the Chernobyl nuclear reactor accident increased public concern about the safety of spacecraft using nuclear technology. While three nuclear powered spacecraft had been launched before 1986 with little public interest, future nuclear powered missions would see significantly more public concern and require NASA to increase its efforts to communicate mission risks to the public. In 1987 a separate risk communication area within the Launch Approval Planning Group of the Jet Propulsion Laboratory was created to address public concern about the health, environmental, and safety risks of NASA missions. The lessons learned from the risk communication strategies developed for the nuclear powered Galileo, Ulysses, and Cassini missions are reviewed in this paper and recommendations are given as to how these lessons can be applied to future NASA missions that may use nuclear power systems and other potentially controversial NASA missions.

Chernobyl nuclear catastrophe and the high risk potential for mental retardation

The nuclear explosion at Chernobyl nuclear reactor on April 26, 1986, continues to have wide political, social, and medical ramifications. Hot debris from the Chernobyl reactor covered an area of more than 5,000 square kilometers with nearly 20 million curies of radionuclides. Eleven regions with a population of nearly 17 million people, of whom 2.5 million were children below the age of 5 years, suffered some degree of radioactive contamination. These children are currently of elementary school age. One of the tragedies of the explosion is that thousands of these children are at high risk for mental retardation and learning disorders

The Belarus-American (BelAm) thyroid study cohort consists of persons who were 0-18 years of age at the time of exposure to radioactive iodine fallout from the 1986 Chernobyl nuclear power plant accident and who have undergone serial thyroid screenings with referral for fine-needle aspiration biopsy (FNAB) using standardized criteria. We investigated thyrocyte nuclear abnormalities in cytological samples from FNABs in 75 BelAm subjects with single and multiple thyroid nodules and 47 nodular goiter patients from Leningrad, Russia, unexposed to Chernobyl fallout. Nuclear abnormalities examined included internuclear chromosome bridges and derivative nuclei with broken bridges (i.e., ''tailed'' nuclei), which are formed from dicentric and ring chromosomes and thus may be cellular markers of radiation exposure. Among subjects with single-nodular goiter, thyrocytes with bridges were present in 86.8% of the exposed BelAm cohort compared with 27.0% of unexposed controls. The average frequency of thyrocytes with bridges and with tailed nuclei was also significantly higher in the BelAm subjects than in controls. Among subjects with multinodular goiters, thyrocytes with bridges were present in 75.7% of exposed BelAm patients compared with 16.7% of unexposed controls; thyrocytes with tailed nuclei were observed in all of the BelAm subjects but in only 40% of controls, and the mean frequencies of bridges and tailed nuclei were significantly higher in the exposed group. Unusually, long bridges were detected in 29% of BelAm patients with single-nodular goiters and 35% of those with multinodular goiters, while no such abnormalities were observed among patients from the Leningrad region. In the exposed subjects from BelAm, we also found positive correlations between their estimated dose of Iodine-131 from Chernobyl fallout and the frequency of tailed nuclei (p = 0.008) and bridges (p = 0.09). Further study is needed to confirm that these phenomena represent

Some of the territories have naturally increased level of radiation as areas of native radioecological anomalies, but others were polluted as a result of nuclear weapon testing, nuclear waste leakage, and nuclear power plants disasters, such as Chernobyl nuclear power plant (CNPP) and Fukushima. Eventually, the large areas have been strong contaminated with radioactivity isotopes for long term. Despite more than thirty years aftermath the explosion of the CNPP accident, the problems coming from the high radionuclide contamination of the environment and the effects of chronic radiation on living organisms still remain relevant. Because the recent tragedy at the Fukushima Nuclear Power Plant in Japan is chillingly reminiscent of the world's worst nuclear disaster at Chernobyl, Ukraine in 1986. Our research addressing the effects of chronic ionizing radiation on plants, the ongoing success of plants adaptation and transgeneration changes in radio-contaminated Chernobyl area was revealed. The focus our investigation is on a role of the small dose chronic radiation due to plant biodiversity processes because it is a common adverse environmental toxicology factor. In order to characterize proteomes of plants adapting to biodiversity at radio-contaminated Chernobyl area we established non-radioactive and radio-contaminated experimental fields.

This report was prepared by the Nuclear Regulatory Commission (NRC) staff to assess the implications of the accident at the Chernobyl nuclear power plant as they relate to reactor safety regulation for commercial nuclear power plants in the United States. The facts used in this assessment have been drawn from the US fact-finding report(NUREG-1250) and its sources. The general conclusions of the document are that there are generic lessons to be learned but that no changes in regulations are needed due to the substantial differences in the design, safety features and operation of US plants as compared to those in the USSR. Given these general conclusions, further consideration of certain specific areas is recommended by the report. These include: administrative controls over reactor regulation, reactivity accidents, accidents at low or zero power, multi-unit protection, fires, containment, emergency planning, severe accident phenomena, and graphite-moderated reactors

The Chernobyl accident has produced calls for a moratorium on further nuclear power development and construction in the UK or, in the extreme, a phasing out of existing nuclear power stations. Some suggestions as to how to counteract these demands have been collected using published information wherever possible. (author)

Public and political attitudes to nuclear power in Sweden

Wikdahl, C.-E.; Swedish Atomic Forum)

1988-01-01

The first important decisions about a large nuclear programme in Sweden were taken in the early 1960s without any political opposition at all. The first signs of an anti-nuclear movement were seen in 1972, and at the general election in 1976 nuclear power was for the first time the main political issue. It remained so until 1980, when Parliament, after a referendum, decided to phase out nuclear power not later than the year 2010. After that decision, political interest in nuclear power evaporated, but returned again after the Chernobyl accident in April 1986. Both the decision in Parliament in 1980 and the Government's bill of May 1987 put Sweden in an unique position. Public attitudes and the political situation in Sweden are examined. (author)

Chernobyl: exclusive investigation. How the French nuclear lobby buries the truth in contaminated areas. The After-Chernobyl or 'Living happy' in contaminated area

International Nuclear Information System (INIS)

2006-01-01

According to the results of this inquiry, the CEPN (study centre on assessment of protection in the nuclear sector) has been created by the main actors of the nuclear industrial sector (EFG, Cogema, CEA and IRSN) and is at the origin of the ETHOS and CORE projects. Moreover, these projects have been financed by public funds. It also shows that the FNSEA (farmer trade union) has been allied to the French nuclear lobby for the distribution probably contaminated and radioactive foodstuff. It evokes the case of Belarus researcher who denounced such contamination and the misappropriation of international funds, and who was sent to jail. It comments the collaboration between the French nuclear sector and the Belarus regime, denounces how the truth about Chernobyl has been hidden, the cynical results of the ETOS program which would imply the consumption of contaminated foodstuff in France in case of nuclear accident. Some proposals are made: to dismantle the CEPN, to stop the participation of French organisations to the CORE and FARMING programs, creation of an independent commission on the consequences of the Chernobyl accident, and so on. For the authors, phasing out nuclear is the only solution o avoid a new Chernobyl

Finland has achieved some remarkable achievements in nuclear power production. Existing four plants have some of the best operating records in the world - high capacity factors, low occupational doses and short refuelling outages. Although public opinion was strongly turned against nuclear power after Chernobyl accident, and no decisions for new nuclear plants can be made before next elections in 1991, the nuclear option is still open. Utility companies are maintaining readiness to start new construction immediately after a positive political decision is made. One important component of the good operation history of the Finnish nuclear power plants is connected to the continuous research, development, modification and upgrading work, which is proceeding in Finland. In the following a short description is given on recent activities related to the I and C-systems of the nuclear power plants. (author). 2 tabs

The worldwide future of nuclear power as seen about 25 years ago is presented based on a literature search in the INIS database. The role of nuclear power today, after TMI and Chernobyl, in energy supplies and in combating the greehouse effect is evaluated by literature searches in STN databases (e.g. INIS, ETDE, COMPENDEX, CA, ULIDAT, INSPEC). An evaluation is given of the different information contents of bibliographic databases such as INIS and pure information databases such as NLDB. (orig./HP)

Chernobyl and its consequences

Ettemeyer, R.

1986-01-01

The accident of 26 April 1986 in Chernobyl with the immense activity release was a catastrophe which took many victims and will still take many. This fact should not be hidden. This brochure represents an attempt to reflect the poor information from Chernobyl in a generally understandable manner and to assess them. Its goal is especially to make clear why even in maximum accidents in German nuclear power plants there is no danger to the population. The effects of the radioactive substances released after the accident in Chernobyl on Germany are described and put into relation. All presentations and descriptions were kept as models and were simplified and are therefore incomplete. This brochure was not meant to be an educational book; it only tries to respond to the questions raised by the accident in Chernobyl in the minds of non-professionals thus taking away the fear and strengthening the confidence in the safety of German reactors.

Safety in nuclear power plants

International Nuclear Information System (INIS)

Koeberlein, K.

1987-01-01

In nuclear power plants large amounts of radioactive fission products ensue from the fission of uranium. In order to protect the environment, the radioactive material is confined in multiple 'activity barriers' (crystal matrix of the fuel, fuel cladding, coolant boundary, safety containment, reactor building). These barriers are protected by applying a defense-in-depth concept (high quality requirements, protection systems which recognize and terminate operational incidents, safety systems to cope with accidents). In spite of a favorable safety record of German nuclear power plants it is obvious - and became most evident by the Chernobyl accident - that absolute safety is not achievable. At Chernobyl, however, design disadvantages of that reactor type (like positive reactivity feedback of coolant voiding, missing safety containment) played an important role in accident initiation and progression. Such features of the Russian 'graphite-moderated pressure tube boiling water reactor' are different from those of light water reactors operating in western countries. The essential steps of the waste management of the nuclear fuel cycle ('Entsorgung') are the interim storage, the shipment, and the reprocessing of the spent fuel and the final repository of radioactive waste. Reprocessing means the separation of fossil material (uranium, plutonium) from radioactive waste. Legal requirements for radiological protection of the environment, which are identical for nuclear power plants and reprocessing plant, are complied with by means of comprehensive filter systems. Safety problems of a reprocessing plant are eased considerably by the fact that system pressures, process temperatures and energy densities are low. In order to confine the radioactive waste from the biosphere for a very long period of time, it is to be discarded after appropriate treatment into the deep geological underground of salt domes.

Psychological lessons of Chernobyl

International Nuclear Information System (INIS)

Abramova, V.N.

1989-01-01

Up to the time of the disaster, the Chernobyl Nuclear Power Plant was regarded as one of the best in the USSR, and the city of Pripyat, housing the plant's staff, was rightly called one of the most comfortable. Also, the psychological climate of the plant provided no causes for worry. This was a worked-in team, composed of seasoned and knowledgeable experts. How can one then explain the events that happened in such an unlikely place. Isn't there a danger that the situation will repeat itself? The author considers the question and other psychological aspects of the Chernobyl incident

Chernobyl versus Basic Law

The author discusses the terms 'remaining risk to be accepted' and 'remainder of the aggregate risk', and explains the line of action to be adopted in compliance with the Constitution in order to respond to the event at Chernobyl: The Constitution demands maximum acceptable limits to be defined as low as possible. The author discusses the various dose estimations and the contradictions to be observed in this context. He states that the Chernobyl accident has done most harm to our legal system, as the basic right of freedom from injury has been ploughed under with the radioactivity that covered the soil after the Chernobyl accident. But, he says, a positive effect is that the idea of abandoning nuclear power as too dangerous a technology has gained more widespread acceptance. (HSCH).

Nuclear power: safety and prospects

Miniere, D.

Despite the Fukushima accident new countries are willing to use nuclear power and as a nuclear accident somewhere is a nuclear accident everywhere, all countries are concerned with nuclear safety. A big association that would gather all the national Safety Authorities would be an efficient tool to promote and improve safety at the world scale and may be the unique available tool as no country would let a foreign authority to drive its own nuclear industry. An important lesson from Fukushima and Chernobyl accidents is that the signature of a big nuclear accident is not the number of casualties (it will always be limited) but the importance of the radioactive contamination. The question is how to make this long-term and long-range contamination impossible to happen, it is the mission of nuclear safety. (A.C.)

Despite the catastrophic accident at the Chernobylsk 4 reactor in 1986, the Ukraine is currently expanding its nuclear industry. The government is committed to increasing the share of nuclear output to 40% of the country`s electric power and the Chernobyl plant is included in this plan. All the Chernobyl reactors were closed down at the time of the accident, but units 1, 2 and 3 had all been restarted after safety modifications by December 1987. A fire in the turbine hall of unit 2 in 1991 resulted in the closure of that reactor and precipitated a political decision to close the entire plant by 1993. The economic consequences of such action and the safe operation of the remaining two reactors led, however, to the reversal of that decision. Work is now far advanced on unit 2 for a restart in 1996 and the management wants to upgrade all three reactors according to IAEA guidelines. Nevertheless, the question of closure of the Chernobyl plant remains in the air. A conditional acceptance of closure by 2000 has been made by the Ukraine provided the shortfall in power is taken up by a new gas-fired station. International finance is being sought for decommissioning, for urgent action on the decaying sarcophagus of unit 4, and for the gas-fired plant. Closure of the plant, given the social upheaval of the accident and recent political events, could contribute to the health of the Ukrainian national psyche. (UK).

Nuclear power and the environment

International Nuclear Information System (INIS)

Mackerron, Gordon; Berkhout, Frans

1990-01-01

The environmental effects of nuclear power discussed in this paper are specifically the effects of radiation on human populations, either directly or through the food chain. Controlling the environmental effects of nuclear power has two dimensions, waste management and safety. Regulatory controls aim to keep the risk of death due to man-made radiation down to what is thought to be an acceptable level; the background to the establishing of such levels is examined. The scale of the nuclear industry is outlined. In industrial countries with nuclear power, with the possible exception of the USA and USSR which have extensive nuclear weapons programmes, most radioactive wastes arise in the civil nuclear fuel cycle; medical, research and industrial users of nuclear materials produce the rest. The extreme variety of materials included in radioactive wastes is highlighted. Approaches to the management of different kinds of radioactive waste are discussed; the particular problems associated with reactor decommissioning are considered. The enormous potential harm of serious accidents at nuclear power plants through a release of large quantities of radionuclides into the environment has been a dominant influence in the design of reactors. The accidents at Three Mile Island and Chernobyl underline the need for careful examination of management issues as well as design and operational failures. Finally, the catastrophic effects of a full scale nuclear war are briefly considered within the context of nuclear proliferation and international security. (UK)

Swiss operating experience: availability and post-Chernobyl upgrading

International Nuclear Information System (INIS)

Wenger, H.

1988-01-01

Switzerland started its era of nuclear power with the foundation stone for the country's first nuclear power unit (Beznau-1) onSeptember 6, 1965. Up to that date, Switzerland was the classic country for hydropower, negligible amounts of electricity being produced by fossil-fuelled plants. Today, nuclear accounts for close to 40 % of Swiss total electricity generation. Whwn credits for lifetime capacity factors of each individual plant are combined, Switzerland tops the world list for light water reactor performance over many years. The Chernobyl reactor type RBMK-1000 has very little in common with the light water reactors operating in Switzerland, so one would certainly not expect any direct influence on Swiss plant design, operation or maintenance as an immediate consequence of the accident. Some important safety measures against severe accidents are currently being implemented. These measures were not a direct outcome of the Chernobyl accident and were already in discussion quite some time before. With this action, the proper position of nuclear power to meet the ever increasing demand for electricity in Switzerland will hopefully again find greater public acceptance. 1 tab

Tracking the cloud from Chernobyl

ApSimon, Helen; Wilson, Julian

1986-01-01

In the aftermath of the accident at Chernobul nuclear power station, many scientists are studying how the radionuclides from the reactor's core dispersed across Europe and became deposited on the ground. A group in the Department of Mechanical Engineering at Imperial College have developed a computer model, MESOS, specifically to study the transport of pollutants in the atmosphere over very large distances. In the past, this model has been used to study the potential consequences of hypothetical accidents at nuclear power plants in neighbouring countries. Now it has been used to estimate where the radioactivity from Chernobyl went. The Chernobyl model is explained and some estimates from the MESOS model are presented. By comparing the model estimates with observations a full assessment of the environmental consequences of the accident will be possible. It should be possible to find out the way in which pollutants travel long distances, how they are deposited on the ground and their transport through food chains. (U.K.)

It is suggested that the explosion at the Chernobyl-4 reactor in April 1986 was a nuclear explosion. The evidence for this is examined. The sequence of events at Chernobyl is looked at to see if the effects were like those from a nuclear explosion. The question of whether a United Kingdom reactor could go prompt critical is discussed. It is concluded that prompt criticality excursions are possible, but the specific Chernobyl sequence is impossible. (UK)

Process of public attitudes toward nuclear power generation

Shimooka, Hiroshi

1993-01-01

The Japanese public attitudes toward nuclear power generation had become negative year by year. After the Chernobyl accident, a percentage of the unfavorable respondent toward nuclear power generation has dramatically increased, and a new type of anti-nuclear movement has been observed. On the basis of our public opinion polls, the reason for this increase was found to be primarily decrease of sense of usefulness rather than increase of sense of nueasiness about nuclear safety. Particularly, social factors (change of life style, progress of civilian consciousness, credibility of the existing institutional system etc.) have influence on the attitude of either pro or anti-nuclear. Based on the above observation, we have inferred that process of the public attitudes has two flows arising from the above social factors, one is the usefulness and the other is the easiness about nuclear safety, and have formulated a model representing the process of public attitudes toward nuclear power.

Safety policy for nuclear power development

International Nuclear Information System (INIS)

Uchida, Hideo

1987-01-01

The report discusses various aspects of the safety policy for nuclear power development in Japan. Nuclear power development over three decades in Japan has led to operating performance which is highly safe and reliable. This has been appreciated internationally. Discussed here is the Japanese basic safety policy for nuclear power development that is essential first to design, manufacture and construction using high technology. The current careful quality assurance and reliable operation management by skilled operators are relied upon, on the basis of the fact that measures to prevent abnormal events are given first priority rather than those to mitigate consequences of abnormal events or accidents. Lessons learned from accidents and failures within or outside Japan such as the TMI accident and Chernobyl accident have been reflected in the improvement of safety through careful and thorough examinations of them. For further improvement in nuclear safety, deliberate studies and investigations on severe accidents and probabilistic safety assessment are considered to be important. Such efforts are currently being promoted. For this purpose, it is important to advance international cooperation and continue technical exchanges, based on operation experience in nuclear power stations in Japan. (Nogami, K.)

The radioactive substances released following the accident at the Chernobyl nuclear power plant were distributed by atmospheric transport over large parts of Europe. Due to dry and wet deposition processes, soil and Plants were contaminated. The ''radioactive cloud'' was first monitored on the 29th of April by near surface measurement stations; by the 30th of April the whole of southern Germany was affected. The contaminated air then spread out in both westerly and northerly directions, resulting in increased airborne radioactivity over the entire country within the following days. Airborne radionuclides were deposited on soil and plants in dry form as well as by precipitation. Locally varying deposits resulted from different activity concentrations in aerosols and very large differences in the intensity of precipitation during the passage of contaminated air masses. Rain fails were particularly heavy in Germany during the time the cloud was passing, especially south of the Danube where on average 2,000 to 50,000 Bq of Cs-137 was deposited per square meter on soil, and in some cases even as much as 100,000 Bq per square meter

1993-11-01

The breakup of the former Soviet Union and other political changes in eastern and central Europe have opened up the area to closer scrutiny than was previously possible. Because of the accident at Chernobyl, nuclear power is one of the subjects that western nations have had a great deal of interest in exploring. The former Soviet Union designed and/or helped build more than 60 civilian reactors in the region. Most of these reactors follow one of two distinctly different designs: the VVER, or pressurized water reactor series; and the RBMK, which is a graphite-moderated, multi-channel reactor (the so-called Chernobyl type). In addition, there are two fast-breeder reactors and four graphite-moderated boiling water reactors for combined heat and power in operation in Russia. These last two designs are not widely distributed and so are not discussed in detail in this report. As noted above, the safety of Soviet-designed reactors has been of great concern around the world since the catastrophic events at Chernobyl in 1986. This paper will briefly describe the technology involved. It will also examine the main safety concerns, both technical and organizational, associated with each reactor type. In addition, the paper will review the nuclear power programs in the new countries emerging from the former Soviet Union and its satellites and discuss the international efforts underway to address the most pressing problems.

Nuclear power in Germany

Schaefer, A.

1990-01-01

I want to give some ideas on the situation of public and utility acceptance of nuclear power in the Federal Republic of Germany and perhaps a little bit on Europe. Let me start with public perception. I think in Germany we have a general trend in the public perception of technology during the last decade that has been investigated in a systematic manner in a recent study. It is clear that the general acceptance of technology decreased substantially during the last twenty years. We can also observe during this time that aspects of the benefits of technology are much less reported in the media, that most reporting by the media now is related to the consequences of technologies, such as negative environmental consequences. hat development has led to a general opposition against new technological projects, in particular unusual and large. That trend is related not only to nuclear power, we see it also for new airports, trains, coal-fired plants. here is almost no new technological project in Germany where there is not very strong opposition against it, at least locally. What is the current public opinion concerning nuclear power? Nuclear power certainly received a big shock after Chernobyl, but actually, about two thirds of the German population wants to keep the operating plants running. Some people want to phase the plants out as they reach the end-of-life, some want to substitute newer nuclear technology, and a smaller part want to increase the use of nuclear power. But only a minority of the German public would really like to abandon nuclear energy

Full Text Available This paper describes the use of a photostimulable phosphor screen imaging technique to detect radioactive contamination in the leaves of wormwood (Artemisia vulgaris L and fern (Dryopteris filix-max CL. Schoff plants affected by the Chernobyl nuclear power plant accident. The imaging plate technology is well known for many striking performances in two-dimensional radiation detection. Since imaging plate comprises an integrated detection system, it has been extensively applied to surface contamination distribution studies. In this study, plant samples were collected from high- and low-contaminated areas of Ukraine and Belarus, which were affected due to the Chernobyl accident and exposed to imaging technique. Samples from the highly contaminated areas revealed the highest photo-stimulated luminescence on the imaging plate. Moreover, the radio nuclides detected in the leaves by gamma and beta ray spectroscopy were 137Cs and 90Sr, respectively. Additionally, in order to assess contamination, a comparison was also made with leaves of plants affected during the JCO criticality accident in Japan. Based on the results obtained, the importance of imaging plate technology in environmental radiation monitoring has been suggested.

The future of nuclear power

Energy production and use will contribute to global warming through greenhouse gas emissions in the next 50 years. Although nuclear power is faced with a lot of problems to be accepted by the public, it is still a significant option for the world to meet future needs without emitting carbon dioxide (CO 2 ) and other atmospheric pollutants. In 2002, nuclear power provided approximately 17% of world energy consumption. There is belief that worldwide electricity consumption will increase in the next few years, especially in the developing countries followed by economic growth and social progress. Official forecasts shows that there will be a mere increase of 5% in nuclear electricity worldwide by 2020. There are also predictions that electricity use may increase at 75%. These predictions require a necessity for construction of new nuclear power plants. There are only a few realistic options for reducing carbon dioxide emissions from electricity generation: Increase efficiency in electricity generation and use; Expand use of renewable energy sources such as wind, solar, biomass and geothermal; Capture carbon dioxide emissions at fossil-fuelled electric generating plants and permanently sequester the carbon; Increase use of nuclear power. In spite of the advantages that nuclear power has, it is faced with stagnation and decline today. Nuclear power is faced with four critical problems that must be successfully defeat for the large expansion of nuclear power to succeed. Those problems are cost, safety, waste and proliferation. Disapproval of nuclear power is strengthened by accidents that occurred at Three Mile Island in 1979, at Chernobyl in 1986 and by accidents at fuel cycle facilities in Japan, Russia and in the United States of America. There is also great concern about the safety and security of transportation of nuclear materials and the security of nuclear facilities from terrorist attack. The paper will provide summarized review regarding cost, safety, waste and

A review of events which have led to the public opposition to nuclear power is given. Arguments of 'Greens' and social structure of this movement are exposed. INIS Database was used for finding the main directions of works in nuclear power in the World and for their comparison with such directions in thermal power field. The results obtained demonstrate that the 'Greens' strongly exaggerate the nuclear hazards and do not pay due attention to environmental pollution from fossil-fuel power plants. Attitude of the population in Ukraine to nuclear power after Chernobyl accident is analysed and actions for public opinion balancing are proposed

For the current on-site evaluation of the environmental contamination and contributory external exposure after the accident at the Chernobyl Nuclear Power Plant (CNPP) and the nuclear tests at the Semipalatinsk Nuclear Testing Site (SNTS), the concentrations of artificial radionuclides in soil samples from each area were analyzed by gamma spectrometry. Four artificial radionuclides (241Am, 134Cs, 137Cs, and 60Co) were detected in surface soil around CNPP, whereas seven artificial radionuclides (241Am, 57Co, 137Cs, 95Zr, 95Nb, 58Co, and 60Co) were detected in surface soil around SNTS. Effective doses around CNPP were over the public dose limit of 1 mSv/y (International Commission on Radiological Protection, 1991). These levels in a contaminated area 12 km from Unit 4 were high, whereas levels in a decontaminated area 12 km from Unit 4 and another contaminated area 15 km from Unit 4 were comparatively low. On the other hand, the effective doses around SNTS were below the public dose limit. These findings suggest that the environmental contamination and effective doses on the ground definitely decrease with decontamination such as removing surface soil, although the effective doses of the sampling points around CNPP in the present study were all over the public dose limit. Thus, the remediation of soil as a countermeasure could be an extremely effective method not only for areas around CNPP and SNTS but also for areas around the Fukushima Dai-ichi Nuclear Power Plant (FNPP), and external exposure levels will be certainly reduced. Long-term follow-up of environmental monitoring around CNPP, SNTS, and FNPP, as well as evaluation of the health effects in the population residing around these areas, could contribute to radiation safety and reduce unnecessary exposure to the public.

After Chernobyl. Possibilities of phasing out nuclear power in Sweden

International Nuclear Information System (INIS)

1987-01-01

According to the currently applicable Parliamentary decision, the phasing out of nuclear power in Sweden must be completed by the year 2010. The National Energy Administration has analyzed the following questions. If it were to become evident that operating several or all of the Swedish nuclear power plants entailed serious risks, what possibilities would there be of phasing them out in the short term or over a longer period. And what would the consequences be with regard to the national economy and the environment? First we report the consequences of a rapid phase-out. Here, it is assumed that several or all nuclear plants would be taken out of operation within a period of two years. Available compensatory resources would be limited to more intensive utilization of existing hydropower, back-pressure plants, combined power and heating plants and oil-fired plants. The second alternative is a phase-out in ten years. Moreover, a case is discussed in which phase-out is planned and implemented from 1987 to 2005. Such a plan would provide industry more time to adjust, while a number of alternative techniques and fuels could be used to replace nuclear power. The consequences of the different phase-out alternatives can be described only within a framework of certain assumptions regarding the worldwide development. Important factors here include fuel prices and economic trends. Environmental restrictions comprise another important prerequisite

The report describes how the different parties of the nuclear debate react to, and deal with, the information that arises on the issue, i.e. the process that leads to decision making. After the Chernobyl accident, a public enquiry was made, to form a base for decisions regarding the future energy policy of Sweden, including the phasing-out of nuclear power. The differing interpretations and uses of the results of this enquiry are studied, in the hope to clarify and separate factual and value-based appreciations of different energy policy alternatives

The health status of some 6,000 workers from Latvia who went to clean-up the Chernobyl Nuclear Power Plant (CNPP) site following the explosion on 26 April 1986 has been analyzed. The data on these workers have been recorded in the Latvian State Register of Occupational disease patients and people exposed to ionizing radiation due to Chernobyl NPP accident (Latvian State Register) that was established in 1994. From these data, estimates have been made of external ionizing radiation to which these workers were exposed together with observations on the impact of exposure to heavy metals (especially lead and zinc) and radioactive isotopes released during the reactor 'meltdown'. These factors along with psycho-emotional and social-economic stresses account for a marked excess of mortality and morbidity in the group of CNPP accident clean-up workers compared with that of the non-exposed normal Latvian population adjusted for age and sex. The number of diseases or conditions in the CNPP accident clean-up workers has progressively risen from an average of 1.3 in 1986 to 10.9 in 2007. This exceeds for the Latvian population when adjusted for age and sex. The most serious conditions affect the nervous, digestive, respiratory, cardiovascular, endocrine (especially thyroid) and immunological systems. While the morbidity associated with diseases of the respiratory and digestive systems has decreased in recent years that in the other systems is increasing. In recent years, there has been an increased occurrence of cancers affecting the thyroid, prostate and stomach. Clinical and laboratory investigations suggest that surviving CNPP accident clean-up workers exhibit signs of immuno-inflammatory reactions causing premature aging with evidence of autoimmune diseases and immunological deficiencies or abnormalities. It is suggested that the CNPP accident clean-up workers may have a specific syndrome, the 'Chernobyl post-radiation neurosomatic polypathy', due to sustained oxidant

Nuclear Power after Fukushima

2011-01-01

On 11 March 2011 Japan suffered an earthquake of very high magnitude, followed by a tsunami that left thousands dead in the Sendai region, the main consequence of which was a major nuclear disaster at the Fukushima power station. The accident ranked at the highest level of severity on the international scale of nuclear events, making it the biggest since Chernobyl in 1986. It is still impossible to gauge the precise scope of the consequences of the disaster, but it has clearly given rise to the most intense renewed debates on the nuclear issue. Futuribles echoes this in the 'Forum' feature of this summer issue which is entirely devoted to energy questions. Bernard Bigot, chief executive officer of the technological research organization CEA, looks back on the Fukushima disaster and what it changes (or does not change) so far as the use of nuclear power is concerned, particularly in France. After recalling the lessons of earlier nuclear disasters, which led to the development of the third generation of power stations, he reminds us of the currently uncontested need to free ourselves from dependence on fossil fuels, which admittedly involves increased use of renewables, but can scarcely be envisaged without nuclear power. Lastly, where the Fukushima disaster is concerned, Bernard Bigot shows how it was, in his view, predominantly the product of a management error, from which lessons must be drawn to improve the safety conditions of existing or projected power stations and enable the staff responsible to deliver the right response as quickly as possible when an accident occurs. In this context and given France's high level of dependence on nuclear power, the level of use of this energy source ought not to be reduced on account of the events of March 2011. (author)

About 1500 people were involved in emergency operations on 26-27 April 1986 at the site of the Chernobyl Nuclear Power Plant. They worked in different working conditions and were exposed to aerosols of different characteristics. The Chernobyl accident was the first accident in which, when the reactor core was destroyed, aerosol of the dispersed spent nuclear fuel became a significant source of internal and external exposure for a large group of people. Detailed information on the properties of the Chernobyl aerosol for the first post-accident period is absent. Therefore, results of in vivo monitoring of the witnesses of the Chernobyl accident can be an important source of information for assessing the radiological properties of the Chernobyl aerosol.

On nuclear development, it is natural that safety is the most important condition. However, when occurring an accident in spite of earnest efforts on safety pursuit, it is essential for a technical developer to absorb some lessons from its contents as much as possible and show an attitude to use thereafter. The Chernobyl accident brought extraordinarily large damage in the history of nuclear technology development. Therefore, the edition group of the Japan Society of Atomic Energy introduced opinions of three groups of the Society (that is, groups on reactor physics, nuclear power generation, and human-machine system research) with some description on cause analysis of the accident and its result and effect. And, here was also shown four basic difference on design between RMBK type reactor in Chernobyl and LWR type reactor supplied in Japan. (G.K.)

Nuclear power of Ukraine commenced from Chernobyl NPP, where the first unit was put into operation at 1977. At present in Ukraine there are 4 running NPPs with a total installed capacity 11880 MW where more than 40 % of electricity is generated. Elaborated Atomic Energy Strategy Development for the period till 2030 after the commissioning of two new units in 2004 foresees to keep the total installed capacity around 14000 MW. Analysis on the maintenance of such level and the solution of other problems, related to nuclear energy is carried out. Among them: nuclear fuel cycle, handling of radioactive wastes, decommissioning and others. Thus nuclear energy plays and will play the important role to ensure the electricity generation in Ukraine

To solve the problem of atomic bomb, a powerful nuclear industrial complex has been established in the Soviet Union. This complex has developed a high scientific and engineering potential and enlisted the best science and engineering experts. Strict administration, rigid discipline in execution and operation, to secrecy limiting both internal and external interactions were typical of the complex which presented a state within the state with the inside divide by rigid barriers and protected from the outside by iron curtain. When the atomic bomb was designed and tested the search for a field of application for the nuclear potential available was started: nuclear power plants, nuclear power facilities for submarines and ships, nuclear aircraft and rocket engines, space nuclear facilities. Such were the conditions of forming the nuclear power in USSR. But this nuclear military complex has failed to prevent the Chelyabinsk accident which involved considerable radiological effects. The national industry could not adopt quickly the work style established in a nuclear complex and relative high technologies because of low educational and technical level and poor technological discipline. The results are known: the Chernobyl accident coincided in time with the beginning of the reconstruction of the System, the result of which was this accident. This paper describes the current status of the nuclear park, shows the problems of safety, maintenance, retrofitting, reconstruction or decommissioning. Statistical data on nuclear power in the power production program are also given

The safety of nuclear power plants

Energy Technology Data Exchange (ETDEWEB)

1988-01-01

Do nuclear power plants present an unjustifiable risk Can there be confidence in their safety The Uranium Institute invited a group of senior safety experts from eight different Western countries operating different types of reactors to provide an authoritative explanation for non-specialists of the basic principles of reactor safety, their application and their implications. The report presents the group's opinion on the level of safety achieved in the Western nuclear power plants with which the authors are directly familiar. Although many of the points made may well also be true for non-Western reactors, the report does not cover them except where specifically stated. It does describe and discuss the causes of the Chernobyl disaster. It does not compare nuclear power with other fuels, nor does it deal with its benefits, since however great the benefits from the peaceful use of nuclear power, and its own advantages over other fuels, they could not compensate for lack of safety. The conclusion reached is that the risk associated with electricity production at nuclear power plants can be kept very low. Proper use of the extensive knowledge available today can guarantee operation of nuclear power plants at very high safety levels, carrying very low risks, both to health and of contamination of the environment: risks that are continually lowered by upgrading existing plants and their operation, and by the design of future power plants.

Problems discussed at the IAEA International Conference on nuclear power indices and safety held in Vienna from 28 September to 2 October, 1987 are considered. Representatives from 40 countries and 12 international organizations participated in the conference. It is marked that by the end of this century nuclear power plant capacities in developing countries will increase by more than twice. In developed countries increase of installed capacity by 65 % is forecasted. It is stressed that competently constructed and operated NPPs will be successfully competing with coal-fueled power plants in the majority of the world regions. Much attention was paid to reports on measures taken after Chernobyl' accident and its radiation effects on people helth. It is shown that parallel with fundamental theoretical studies on NPP safety as a complex engineering system much attention is paid to some problems of designing and operation of such facilities. Fuel cycle problems, radioactive waste and spent fuel storage and disposal in particular, are considered

To present previously unavailable data on the use of stem cell administration to aid recovery of victims of the Chernobyl disaster. On 26 April 1986, an accident at Unit 4 of the Chernobyl Nuclear Power Plant took place during the planned test of one of the safety systems. The diagnosis of acute radiation syndrome (ARS) was confirmed in 134 individuals exposed to high levels of radiation. There were nine patients heretofore unreported in the scientific literature who underwent intraosseous injections of allogeneic bone marrow cells in Kyiv. Transplantation was associated with significantly shortened time to recovery of granulocyte and platelet counts in these patients. While current guidelines would certainly include the use of cytokines, these data provide an indication of the effectiveness of stem cell transplant to treat victims of radiation exposure.

Nuclear power for sustainable development. Current status and future prospects

Interest in nuclear power has been revived as a result of volatile fossil fuel prices, concerns about the security of energy supplies, and global climate change. This paper describes the current status and future plans for expansion of nuclear power, the advances in nuclear reactor technology, and their impacts on the associated risks and performance of nuclear power. Advanced nuclear reactors have been designed to be simpler and safer, and to have lower costs than currently operating reactors. By addressing many of the public health and safety risks that plagued the industry since the accidents at Three Mile Island and Chernobyl, these reactors may help break the current deadlock over nuclear power. In that case, nuclear power could make a significant contribution towards reducing greenhouse gas emissions. However, significant issues persist, fueling reservations among the public and many decision makers. Nuclear safety, disposal of radioactive wastes, and proliferation of nuclear explosives need to be addressed in an effective and credible way if the necessary public support is to be obtained.

It was shocking not just because of the technical failure - unfortunately such things happen from time to time - but as a social and political failure. The Chernobyl catastrophe undermined and exposed the false, vicious and inhumane Soviet totalitarian system. The Chernobyl explosion initiated the disintegration of the corrupt Communist regime - a regime which had been deemed unshakeable in the USSR. (author)

Investigations on Health Conditions of Chernobyl Nuclear Power Plant Accident Recovery Workers from Latvia in Late Period after Disaster

Reste Jeļena

2016-10-01

Full Text Available The paper summarises the main findings on Chernobyl Nuclear Power Plant (CNPP accident recovery workers from Latvia and their health disturbances, which have been studied by the authors during the last two decades. Approximately 6000 persons from Latvia participated in CNPP clean-up works in 1986–1991. During their work period in Chernobyl they were exposed to external as well as to internal irradiation, but since their return to Latvia they were living in a relatively uncontaminated area. Regular careful medical examinations and clinical studies of CNPP clean-up workers have been conducted during the 25 years after disaster, gathering knowledge on radiation late effects. The aim of the present review is to summarise the most important information about Latvian CNPP clean-up worker health revealed by thorough follow-up and research conducted in the period of 25 years after the accident. This paper reviews data of the Latvian State Register of Persons Exposed to Radiation due to CNPP Accident and gives insight in main health effects found by the researchers from the Centre of Occupational and Radiological Medicine (Pauls Stradiņš Clinical University Hospital and Rīga Stradiņš University in a number of epidemiological, clinical, biochemical, immunological, and physiological studies. Latvian research data on health condition of CNPP clean-up workers in the late period after disaster indicate that ionising radiation might cause premature ageing and severe polymorbidity in humans.

Effects of the Chernobyl accident on public perceptions of nuclear plant accident risks

1990-01-01

Assessments of public perceptions of the characteristics of a nuclear power plant accident and affective responses to its likelihood were conducted 5 months before and 1 month after the Chernobyl accident. Analyses of data from 69 residents of southwestern Washington showed significant test-retest correlations for only 10 of 18 variables--accident likelihood, three measures of impact characteristics, three measures of affective reactions, and hazard knowledge by governmental sources. Of these variables, only two had significant changes in mean ratings; frequency of thought and frequency of discussion about a nearby nuclear power plant both increased. While there were significant changes only for two personal consequences (expectations of cancer and genetic effects), both of these decreased. The results of this study indicate that more attention should be given to assessing the stability of risk perceptions over time. Moreover, the data demonstrate that experience with a major accident can actually decrease rather than increase perceptions of threat

Materials and methods. Three groups of persons evacuated from Chernobyl zone of alienation were researched: persons aged 10-17 (6517 persons, 18-39 (496 persons, 40-60 (458 persons. The data on the individual radiation doses which affected thyroid gland were selected at the State Register of Ukraine on persons affected by the Chernobyl disaster. Morbidity rate was estimated per 103 man-year for 5-years periods of monitoring. The main results: Time from the moment of Chernobyl accident affected the formation of morbidity structure of evacuated population. It was fixed two peaks of morbidity incidence - initial and in 12 years. The most essential changes in CS morbidity of evacuated population were fixed 26 years later mainly in cere¬brovascular diseases. The coronary artery disease takes the first place in the morbidity structure. Significant dif¬ferences were detected at age-specific aspect. The evacuated adult population aged 18-39 years was the most vulnerable for the development of CS diseases. Adverse health effects confirmed the necessity of further research of CS morbidity with the differentiation of doses affected thyroid gland.

Discussions on the future of the Chernobyl nuclear plant between the Ukrainian government, the Group of Seven Industrial nations (GT) and the European Union (EU) are summarized. At the G7 meeting, a timetable for the closure of the entire station by 2000 was presented by Ukrainian officials. The timetable depends on financial commitments from Western governments. Without these, the project would take 10 to 15 years. Following this meeting, which took place on 16-17th May 1995. EU finance ministers authorized release of a ECU 85 million loan. On 23 May, the European Parliament's Committee on Research, Technology and Energy held a public hearing on the Chernobyl station. The primary topic was a feasibility study on the clean-up of Chernobyl 4 and plans for the sarcophagus. Other matters discussed included the effect of the delays and indecision in settling the plants's future. Safety improvements being made to other RBMKs were not being carried out at Chernobyl because of the expected closure. The replacement of the power now supplied to the Ukraine by the Chernobyl reactors is also an issue. The solution favoured by the Ukraine is to being on-line three VVER-1000s that are currently close to completion. Western governments find this solution difficult to accept, however. (UK)

Implications of the Chernobyl accident for Protective Action Guidance

Miller, Charles W.; Pepper, Andrea J.

The accident that occurred at Unit 4 of the nuclear power station at Chernobyl in the Union of Soviet Socialist Republics on April 26, 1986, was the worst accident in the history of nuclear power. Thirty-one workers and emergency personnel died and more than 200 site personnel were hospitalized as a result of this event Approximately 135,000 persons within 30 km around the reactor were evacuated, and radioactive debris was spread throughout the Northern Hemisphere. There was much public concern generated around the world, and an increased risk of fatal cancel in the world's population is possible as a result of exposure to Chernobyl fallout (USNRC, 1987a). Since the time the Chernobyl accident occurred, many authoritative studies have been published, e.g. USNRC, 1987a. In these studies, differences in design between commercial U.S. reactors and the RBMK pressure-tube reactor at Chernobyl have been emphasized, e.g. USNRC, 1987b. While significant differences in design do exist between these reactors, we believe there are still significant lessons to be learned from the Chernobyl accident for U.S. reactors. The purpose of this paper is to summarize some of the major lessons to be learned related to protective action guidance. The Illinois Department of Nuclear Safety (IDNS) has identified three areas related to protective action guidance for food and water where implications can be drawn from Chernobyl for the U.S.: (1) uniformity of Protective Action Guides (PAGs), (2) incompleteness of U.S. PAGs, and (3) international communications. Following the Chernobyl accident, a variety of protective actions were undertaken by various nations. Furthermore, these actions were initiated, modified, and terminated at different times in different places and, in some instances, were applied on a local or regional basis rather than a national basis (Goldman et al., 1987). One result of this differing application of PAGs was the generation of considerable confusion among decision

Experience from the MTO program at the Forsmark nuclear power plant

Within the nuclear industry there are two events which have had a significant impact on the way of thinking and attitudes to safety, although in different ways. The TMI accident at Harrisburg, USA put the focus on the man-machine interface, the way of working and attitudes to safety. The accident at Chernobyl focused on safety management and safety culture. After the Chernobyl accident, safety culture (IAEA INSAG-4) became a commonly used concept which included an overall perspective on safety and an understanding of the interaction between man, technology and organizational matters (MTO). As a result of this understanding, the MTO concept was introduced at the Forsmark nuclear power plant already in 1988 and is today a conceptual way of thinking which is well integrated in the line organization. One of the purposes of this paper is to present some of the work that has been done at Forsmark nuclear power plant under the heading of MTO, both in the past and more recently.

The accident at the Chernobyl Nuclear Power Plant in 1986 led to a high level of radioactive contamination over wide area in Europe. High radiation-dose exposure to 134 power plant staff and emergency personnel resulted in acute radiation syndrome. The internal radiation exposure by radioactive iodine-131 caused operated thyroid cancer among more than 6000 children at the time of the accident until 2010. The low dose irradiation by radioactive cesium-137 continues even today, and evacuation and relocation proved a deeply traumatic experience to many people. Since the Chernobyl accident, WHO and IAEA have established a global assistance system to strengthen the activities related to radiation emergency medical preparedness and response network. Fukushima Daiichi Nuclear Power Plant accident in 2011 has also caused many people to evacuate, and great suffering, hardship, and anxiety to the residents of Fukushima Prefecture. Therefore the Fukushima Prefectural Government is now conducting the 'The Fukushima Health Management Survey' to alleviate residents' concerns about radiation and to facilitate suitable healthcare in the future. It is necessary to continue scientific research around Chernobyl and provide accurate information on radiation health effects not only to the Fukushima residents but also toward all over the world.

Youngen, G.

1988-10-01

The role of responding to emergencies at nuclear power plants is often considered the responsibility of the personnel onsite. This is true for most, if not all, of the incidents that may happen during the course of the plant's operating lifetime. There is however, the possibility of a major accident occurring at anytime. Major nuclear accidents at Chernobyl and Three Mile Island have taught their respective countries and communities a significant lesson in local emergency preparedness and response. Through these accidents, the rest of the world can also learn a great deal about planning, preparing and responding to the emergencies unique to nuclear power. This bibliography contains books, journal articles, conference papers and government reports on emergency response to nuclear power plant accidents. It does not contain citations for ''onsite'' response or planning, nor does it cover the areas of radiation releases from transportation accidents. The compiler has attempted to bring together a sampling of the world's collective written experience on dealing with nuclear reactor accidents on the sate, local and community levels. Since the accidents at Three Mile Island and Chernobyl, that written experience has grown enormously

Accident at the Chernobyl nuclear power plant, october 1991: facts and causes

Ptashkin, A.V.; Fedorenko, G.M.

2006-01-01

An account is given of the unique accident caused by a spontaneous switching of a 330 kV breaker and a full voltage energizing of the practically stand-still non-excited 500 MW turbine generator N 4 at Chernobyl NPP. The subsequent asynchronous mode of operation resulted in a severe non-reparable damage, hydrogen explosion, fault at the terminals and a fire induced collapse of a machine-hall roof. The analysis has shown that, although the accident was aggravated by a number of casual factors, the main cause of its gravity stems from the ignorance of the probability of a non-sanctioned regime of the asynchronous run of the generator, a mistake committed at the stage of the conceptual development of the typical projects of relay and protection systems of large power blocs

The genetic effects and efficiency of repair of single-stranded DNA breaks in natural populations of Arabidopsis growing within a thirty-kilometer zone of the Chernobyl Nuclear Power Station were studied. A direct relationship was found between the level of radioactive contamination and the frequency of embryonal lethal mutations in the Arabidopsis populations studied. A decrease in the efficiency of reparation of single-stranded DNA breaks was found in Arabidopsis plants growing in the contaminated sites. The level of efficiency of DNA reparation was dependent on the duration for which the Arabidopsis population had been growing in the contaminated sites and on the degree of radioactive contamination of the sites. 9 refs., 4 tabs

After briefly describing the Chernobyl reactor accident and its consequences in Western Europe, especially its psychological effects, the French nuclear energy programme is presented in detail. The role of standardization and education as well as of construction time and cost is pointed out. Moreover, the results of the programme are given including extension of the capable French nuclear power industry, economical and ecological benefits. Future measures such as increase of the flexibility of nuclear power plants, improved fuel management, reduction of personnel radiation doses and employment of advanced reactors (the reactor system N4) will facilitate French efforts to free the country from mineral oil and coal imports.

On April 26th 1986, the worst accident in the history of commercial nuclear power generation occurred at the Chernobyl Nuclear Power Station some 60 miles north of Kiev in the Ukraine. This article describes the sequence of events that occurred and the consequences of the accident. There was extensive damage to the Unit 4 reactor and the building which housed it. Some 31 people have died as a result of the accident either directly or as a result of receiving lethal radiation doses. A significant release of fission products occurred, contaminating land around the station and requiring the evacuation of around 135,000 people from their homes. The radioactive cloud generated over many days was carried by winds to all parts of Europe where there was a varying degree of public concern. The contamination resulted in restrictions on the consumption of meat and vegetables. The latent health effects may not be statistically significant when viewed against the normal mortality rate over the next 40 years. (author)

The Electricity Generating Authority of Thailand (EGAT), the main power producer in Thailand, was first interested in nuclear power as an electricity option in 1967 when the electricity demand increased considerably for the first time as a result of the economic and industrial growth. Its viability had been assessed several times during the early seventies in relation to the changing factors. Finally in the late 1970s, the proceeding with nuclear option was suspended for a variety of reasons, for instance, public opposition, economic repercussion and the uncovering of the indigenous petroleum resources. Nonetheless, EGAT continued to maintain a core of nuclear expertise. During 1980s, faced with dwindling indigenous fossil fuel resources and restrictions on the use of further hydro as an energy source, EGAT had essentially reconsidered introducing nuclear power plants to provide a significant fraction to the long term future electricity demand. The studies on feasibility, siting and environmental impacts were conducted. However, the project was never implemented due to economics crisis in 1999 and strong opposition by environmentalists and activists groups. The 1986 Chernobyl disaster was an important cause. After a long dormant period, the nuclear power is now reviewed as one part of the solution for future energy supply in the country. Thailand currently relies on natural gas for 70 percent of its electricity, with the rest coming from oil, coal and hydro-power. One-third of the natural gas consumed in Thailand is imported, mainly from neighbouring Myanmar. According to Power Development Plan (PDP) 2007 rev.2, the total installed electricity capacity will increase from 28,530.3 MW in 2007 to 44,281 MW by the end of plan in 2021. Significantly increasing energy demand, concerns over climate change and dependence on overseas supplies of fossil fuels, all turn out in a favor of nuclear power. Under the current PDP (as revised in 2009), two 1,000- megawatt nuclear

On April 26, 1986, the Number 4 reactor at the Chernobyl Nuclear Power Station in the Soviet Union suffered a severe accident which destroyed the reactor core and led to a loss of life. The four reactors at this station are of the RBMK-1000 type - boiling-light-water cooled, graphite moderated, vertical pressure-tube reactors, each generating 1000 MW of electricity through two turbines. AECL has carefully studied the accident, and the design of Chernobyl, to see if anything has been overlooked in the CANDU design. This report reviews the results of that study, in particular the relevant features of the Chernobyl design which exacerbated the accident, and compares them to the CANDU 600 design. A number of issues (the sign of the void coefficent and the pressure-tube design) have also been given some international prominence in the post-Chernobyl analysis; these are discussed in this report and shown to be irrelevant to the CANDU design. Finally this report describes the subjects identified for further design follow-up in Canada

The author, living in Moscow at the time, was traveling by night train to visit family in Kiev at the time of the chernobyl accident. He recalls a passenger in his compartment asking if anyone had noticed in the morning press about the explosion in Chernobyl. In Kiev, about 50 mi from Chernobyl by air, he noted on arrival that everyone was calm - the city quiet with no rumors or gossip. He contrasts this with the world being alert, in despair, full of alarm. On failure to reach old friends by phone, he thought they had left the city for at least 4-day vacations - May 1 and 2 holidays plus Saturday and Sunday. He continues to recount the life as usual situation aided and abetted by the governments lack of information and misinformation on the perilously dangerous radioactivity and extent of the disaster. He notes friends showing him a January 1986 copy of Izvestia with an article about the Chernobyl unit, several months before, being named winner in a competition among all nuclear power stations in the USSR

The book is addressed to a wide range of readers, particularly those with a role in ensuring prevention and overcoming consequences of technological and natural disasters. It may be specially useful to those having a connection with the nuclear power industry.

Emotional consequences of nuclear power plant disasters.

Science.gov (United States)

Bromet, Evelyn J

2014-02-01

The emotional consequences of nuclear power plant disasters include depression, anxiety, post-traumatic stress disorder, and medically unexplained somatic symptoms. These effects are often long term and associated with fears about developing cancer. Research on disasters involving radiation, particularly evidence from Chernobyl, indicates that mothers of young children and cleanup workers are the highest risk groups. The emotional consequences occur independently of the actual exposure received. In contrast, studies of children raised in the shadows of the Three Mile Island (TMI) and Chernobyl accidents suggest that although their self-rated health is less satisfactory than that of their peers, their emotional, academic, and psychosocial development is comparable. The importance of the psychological impact is underscored by its chronicity and by several studies showing that poor mental health is associated with physical health conditions, early mortality, disability, and overuse of medical services. Given the established increase in mental health problems following TMI and Chernobyl, it is likely that the same pattern will occur in residents and evacuees affected by the Fukushima meltdowns. Preliminary data from Fukushima indeed suggest that workers and mothers of young children are at risk of depression, anxiety, psychosomatic, and post-traumatic symptoms both as a direct result of their fears about radiation exposure and an indirect result of societal stigma. Thus, it is important that non-mental health providers learn to recognize and manage psychological symptoms and that medical programs be designed to reduce stigma and alleviate psychological suffering by integrating psychiatric and medical treatment within the walls of their clinics.Introduction of Emotional Consequences of Nuclear Power Plant Disasters (Video 2:15, http://links.lww.com/HP/A34).

The contents of Chernobyl Record have taken 14 years to compile and this period of time was necessary to enable information to be released from Soviet sources, measurements to be made in the environment, for estimation of radiation doses and for follow-up of the health of population groups which had been exposed. This time frame also includes the 10th anniversary conferences and the completion of joint projects of the European Commission, Ukraine, Belarus and the Russian Federation. It has also enabled me to visit the power plant site, Chernobyl town and Pripyat relatively soon after the accident and also some 10 years later: December 1987 and June 1998. Without such visits some of the photographs in this Record could not have been obtained. Information is also contained in these pages of comparisons of various aspects of the Chernobyl accident with data from the Three Mile Island accident in the USA in 1979, the Hiroshima and Nagasaki atomic bombs, the highly contaminated Techa river area in the Urals in Russia and the accident in Tokaimura, Japan in 1999. The first two chapters are introductory in that they describe terminology which is necessary for an understanding of the remaining chapters. Chapters 3-6 describes the early events: including those leading up to the explosion and then what followed in the immediate aftermath. Chapters 7-8 describe the Sarcophagus and the past and future of nuclear power for electricity generation, including the future of the Chernobyl power station. Chapters 9-11 consider the radiation doses received by various populations, including liquidators, evacuees and those living on contaminated territories: and the contamination of milk by 131 I, and the contamination of other parts of the food chain by 137 Cs. Chapters 12-14 describe the environmental impact of the accident, as does chapter 11. Chapters 15-18 detail the long-term effects on health, including not only the incidence of cancer, but also of non-malignant diseases and

In April 1986 the Unit 4 of Chernobyl NPP was destroyed in the worst accident in history of commercial nuclear power. Unit 4 started operation in 1983 and was a RBMK nuclear power plant (NPP). Over the years, three generations of reactors have emerged which have significant differences, particularly with respect to the safety provisions built into their design. The electric power of the RBMK reactors is 1000 MW(e) except for Ignalina whose power is 1500 MW(e). development of the Kursk Unit 5, currently under construction, has led to many design changes hence it can be thought of as a fourth generation. The first generation units (Leningrad-l and -2, Kursk-1 and Chernobyl-l and -2) designed and built before 1982 when new standards on the design and construction of Nuclear Power Plants (NPPs) OPB-82 were introduced in the Soviet Union. Since then other units have designed and constructed in accordance to these requirements. The safety standards in the U were revised again in 1988 (OPB-88). Since the Chernobyl accident a considerable amount of work has been carried out by Ru designers and PTSMK operators to improve RBMK reactor safety and to eliminate the causes o accident. As a result, major design modifications and operational changes have been implemented. However, safety concerns remain, particularly related to first generation units. In the framework of a Programme on PTSMK safety initiated by the IAEA in 1992, a total of 58 safety issues related to seven topical areas were identified. The issues related to the six design areas were further ranked according to their perceived impact on plant safety. Safety issues connected to operational areas, particularly those related to ensuring that a high safety culture is an underlying basis for operation, were considered very important. It was stressed that all efforts should be made to implement the related recommendations along with d modifications (author)

Chernobyl has become the catchword that reveals the profound difference of opinions among experts and the population on the issue of nuclear energy. In the many discussions in the public media and elsewhere after the Chernobyl accident, technical terms and scientific terminology and analytic data have been used that induced a feeling of helplessness in the general public, simply because people are not familiar with this terminology and subject. What does 'radioactivity' really mean. What damage to health is done by ionizing radiation. Who finds his way through the muddle of measuring units for radiation, such as rem, Becquerel, or Curie. How does a nuclear power plant work. What kind of reactors are operating in Europe. How safe are they. Where are they. What is a reprocessing plant. These are only a few of the many questions the book answers. The information is intended for the general reader, and supplemented by numerous illustrations, maps, tables and graphs.

On april 26, 1986 a major nuclear disaster took place at 1 h 24 min local time, destroying the fourth reactor of the Chernobyl plant. Five years later the consequences of the disaster are still not fully known. Nevertheless the long term future of nuclear energy in the world is uncertain. Questions need to be answered by observing hard facts if emotional attitudes are not to prevail over reality. The reactor and its core were destroyed by an explosion, causing two radioactive jet emissions of iodine 131, followed by caesium 137. Both elements are mainly incorporated in the body via food. The Chernobyl disaster was a consequence of inadequate safety regulations and human error. Enforcement of strict regulations are likely to be highly effective in preventing a further catastrophe. However, governments should consider another possibility. What would be the consequences for public health if a terroristic act deliberately destroyed a nuclear power station

The threat of a major accidental or deliberate event that would lead to hazardous materials emission in the atmosphere is a great cause of concern to societies. This is due to the potential large scale of casualties and damages that could result from the release of explosive, flammable or toxic gases from industrial plants or transport accidents, radioactive material from nuclear power plants (NPPs), and chemical, biological, radiological or nuclear (CBRN) terrorist attacks. In order to respond efficiently to such events, emergency services and authorities resort to appropriate planning and organizational patterns. This paper focuses on the use of atmospheric dispersion modeling (ADM) as a support tool for emergency planning and response, to assess the propagation of the hazardous cloud and thereby, take adequate counter measures. This paper intends to illustrate the noticeable evolution in the operational use of ADM tools over 25 y and especially in emergency situations. This study is based on data available in scientific publications and exemplified using the two most severe nuclear accidents: Chernobyl (1986) and Fukushima (2011). It appears that during the Chernobyl accident, ADM were used few days after the beginning of the accident mainly in a diagnosis approach trying to reconstruct what happened, whereas 25 y later, ADM was also used during the first days and weeks of the Fukushima accident to anticipate the potentially threatened areas. We argue that the recent developments in ADM tools play an increasing role in emergencies and crises management, by supporting stakeholders in anticipating, monitoring and assessing post-event damages. However, despite technological evolutions, its prognostic and diagnostic use in emergency situations still arise many issues. -- Highlights: • Study of atmospheric dispersion modeling use during nuclear accidents. • ADM tools were mainly used in a diagnosis approach during Chernobyl accident. • ADM tools were also used

Eastern Europe's nuclear power. Buying peace of mind

The use of nuclear power to generate electricity is much more widely used in Eastern Europe than it is generally in the West. When these countries were part of the centrally planned economies of the former Soviet Union, many vast reactors were constructed and commissioned. Since the Chernobyl accident in 1986, and following political independence from Russia, many of these huge reactors are under threat of closure. The energy situation in Eastern Europe is acute. The break down of the old order has left individual countries struggling to maintain a power supply. While the debate over the safety, or otherwise, of these giant nuclear power plants continues, there is a continuing dialogue in the West about how to pay for safety improvements to bring these reactors up to international standards of safety.

Since the Chernobyl accident in April 1986, public opinion in France has changed considerably. Four national surveys carried out over the last two-and-a-half years have shown significant decreases in public approval of nuclear energy (43 percent in October 1988). However, there is no current structured opposition to nuclear power plants. The French public takes nuclear power for granted, but prefers solar energy. It is aware that nuclear power will play an important role in energy supply and that EDF did not build more plants than necessary. It has confidence in the French technique (75 percent), in EDF ability to operate nuclear power plants without serious incidents (55 percent), and in the ability of EDF engineers to deal with a serious accident (50 percent) even though they believe a serious accident could occur (75 percent). However, the situation created by the Chernobyl accident resulted in changes to the EDF information policy. EDF undertook extensive information programs on nuclear power and energy matters during the first years of the program 1975 to 1983), and followed them by a period of less extensive information focussed on electricity. Relations around the nuclear power plant sites between EDF and the public, elected representatives and the media, which had always been close, were reinforced. Information packages were prepared and distributed. Contacts with Textbook Publishers have enabled fruitful exchanges of information, especially during visits to nuclear facilities (power plants, fuel enrichment plants, operating simulators). Remarkable results have been seen in the textbooks concerned. Films, usually videocassettes, are loaned out free of charge. Lectures are a channel of information frequently used by schools since they are free, fit well into the program of some grades, and do not take up too much of the students' time.

A Comparative Analysis of the Impact of the IAEA Cooperation Instruments in the Field of Nuclear Safety to Deal with the Fukushima Daiichi Accident vis-a-vis the Chernobyl Accident

On 26 April 1986, an explosion at Unit 4 at the Chernobyl nuclear power plant released a very large amount of radioactive material into the atmosphere. According to the conclusions raised at the “International Forum on Chernobyl´s Nuclear Safety Aspects” held in Vienna from 1 to 3 April 1996, two important causes of the accident were that: “there were significant deficiencies in the design of the reactor – in particular of its shutdown system – and operating procedures were severely violated at the time of the accident” and “there was a lack of safety culture in the organizations responsible for operation and for control: important safety weaknesses had been recognized long before the accident occurred but were not remedied.” Only thanks to the discovery of an increase in environmental radioactivity in Nordic countries the international community was informed about the accident. On 11 March 2011, as one of the consequences of the tsunami waves generated by the Great East Japan Earthquake off the Pacific coast of Japan, the Fukushima Daiichi nuclear power plant accident took place. In his statement to the “International Conference on Chernobyl: Twenty-Five Years On - Safety for the Future” the International Atomic Energy Agency Director General, Mr. Yukiya Amano, pointed out “Chernobyl led to a great step forward in international cooperation in the field of nuclear safety. We now have four safety conventions, two Codes of Conduct, fundamental safety principles and a body of globally recognised IAEA Safety Standards.” [ ] “An international coordinated response system, with the IAEA's Incident and Emergency Centre at its heart, is now in place.” [ ] “We also have an IAEA peer review system, based on the Agency's Safety Standards.” But Mr. Amano also recognized that “despite the great progress made in the last 25 years, more needs to be done to ensure that a ''Safety First'' approach becomes fully

The Chernobyl NPP decommissioning: Current status and alternatives

Mikolaitchouk, H.; Steinberg, N.

1996-01-01

After the Chernobyl accident of April 26, 1986, many contradictory decisions were taken concerning the Chernobyl nuclear power plant (NPP) future. The principal source of contradictions was a deadline for a final shutdown of the Chernobyl NPP units. Alterations in a political and socioeconomic environment resulted in the latest decision of the Ukrainian Authorities about 2000 as a deadline for a beginning of the Chernobyl NPP decommissioning. The date seems a sound compromise among the parties concerned. However, in order to meet the data a lot of work should be done. First of all, a decommissioning strategy has to be established. The problem is complicated due to both site-specific aspects and an absence of proven solutions for the RBMK-type reactor decommissioning. In the paper the problem of decommissioning option selection is considered taking into account an influence of the following factors: relevant legislative and regulatory requirements; resources required to carry out decommissioning (man-power, equipment, technologies, waste management infrastructure, etc.); radiological and physical status of the plant, including structural integrity and predictable age and weather effects; impact of planned activities at the destroyed unit 4 and within the 30-km exclusion zone of the Chernobyl NPP; planed use of the site; socio-economic considerations

Nuclear power: Public opinion in social crisis

International Nuclear Information System (INIS)

Nuclear power in Russia found itself in new conditions, if compared with first five years after Chernobyl. It is coming out of the technology crisis from 1986 and the political crisis of 1991, going deeper and deeper in the hard economic crisis, when the nuclear power plants receive about 10 percent of payments for electricity, produced and supplied to the customers. Economic crisis forms the public attitude about nuclear power under conditions, different from opinion formed during the previous decades, when energy supply was considered practically free of charge. These realities have moved ecological problems to the periphery of public conscience. This was, in particular, shown with all evidence during the parliamentary elections in Russia in 1993, when the Russian 'Green Party' had not achieved any seats in the State Duma. This is also confirmed by sociological polls of Russians done in the last two years. It seems, however, that change of priorities in public opinion had increased attention to the problems of environment in the nearest future are as inevitable, as the forthcoming Russia's and Its nearest neighbours getting out of the state of economic fail down. In these conditions the possibility of nuclear power development will be determined not only by economic factors, but also by the factor of public confidence. The progress in the development of public information programme in the field of nuclear power, if compared with the first years after Chernobyl, is evident. Several governing and coordinating structures exist and work in Russia (Department of Minatom, Inter-departmental Council for information and public relations, similar Department in Rosenergoatom Concern), regional public information centres, special services at many nuclear science and industry enterprises. Similar system works in Ukraine and is being established in Kazakhstan. In antinuclear Belarus, where, nevertheless, the objective need of nuclear power is already reflected in the national

Nuclear power - economics and safety

Jones, P.

The market for steam coal is largely related to its use in electricity production and here it has to compete with hydrocarbon fuels, renewable sources and nuclear power. The criteria for fuel choice by utilities are partly economic, partly environmental, partly questions of convenience and fuel supply diversity, and partly a reaction to public and political pressures. The relative importance attached to these factors and even perceptions of the factors themselves differ from country to country and utility to utility so that there is no universal consensus on the ''right balance'' of alternative means of generation. Some countries like France and Belgium are heavily committed to nuclear power while others like Australia are committed to coal. Most have no overwhelming commitment to any one source and operate a mixture of plants, although some like Sweden and Austria have decided either to phase out or not to operate nuclear plants. The net result is that there are now some 400 nuclear reactors in operation in 26 countries with over 200 under construction or planned. However, nuclear power's future prospects were not helped by the Three Mile Island and Chernobyl accidents. Coal has also suffered over concerns about gaseous emissions, acid rain and the effects of mining operations. Nuclear critics worry about the disposal of radioactive wastes whilst critics of coal use (and fossil/wood-fuel) worry about global climatic effects of carbon dioxide and nitrogen oxides. This paper looks at some of the facts about nuclear power and its future prospects and how they are likely to affect coal demand. It is concluded that coal does not face an easy future. (author)

The enduring lessons of Chernobyl

The major impacts of the Chernobyl accident fall into three categories: the physical impacts, in terms of health and environmental effects; the psycho-social impacts on the affected populations; and the influence of the accident on the nuclear industry worldwide. The physical impacts mark Chernobyl as the site of the most serious nuclear accident in history. The explosions that destroyed the Unit 4 reactor core released a cloud of radionuclides that contaminated large areas of Belarus, Russia and Ukraine. Hundreds of thousands of workers participated in efforts to mitigate the consequences of the accident, and many of these individuals were exposed to substantial radiation doses. The psycho-social impacts were also devastating. Over 100 000 people were evacuated immediately after the accident, and the total number of evacuees from severely contaminated areas eventually reached 350 000 people. While these resettlements helped to reduce the collective dose of radiation, it was deeply traumatic for those involved. The third impact I mentioned is the enormous influence of the Chernobyl accident on the nuclear industry. A decade earlier, the accident at Three Mile Island had already cast doubt on the ability of nuclear power plant operators to prevent severe accidents. Chernobyl had far greater impact; the accident emblazoned itself on public consciousness as proof positive that nuclear safety was an oxymoron. Some countries decided to reduce or terminate further construction of nuclear facilities, and the expansion of nuclear capacity came to a near standstill. It has taken nearly two decades of strong safety performance to repair the industry's reputation. From the time of the accident, the IAEA has been continuously involved in technical assistance and research projects to mitigate the environmental and health consequences in affected areas. Since 1990, more than $15 million has been disbursed through the IAEA technical cooperation programme on a broad range of these

Study of radioactive aerosols in the relocation zone and in the populated areas have been carried out for a number of years. The experiments on modelling resuspension were performed while conducting agricultural work. Nuclear track radiography and alpha spectrometry with radiochemical extraction of plutonium were used as analytical methods for the determination of the transuranium elements contents. The distributions of radioactive particles were obtained as to activity and sizes. Specific activity of 'hot particles' increases with decreasing diameter. In aerosols selected at a distance of more than 10 km from the Chernobyl NPP pure fuel particles with sizes of more than 5 μm were not found. The activity of the finely dispersed fraction of aerosols, which is more dangerous when inhaled by the organism, is comparable with a total activity of large particles

The USSR nuclear power: Expectation of renaissance

When the Soviet specialists presented the data on the causes and consequences of the largest world nuclear accident to the world community in 1986 and even in a year after the Chernobyl catastrophe, they kept certain optimism concerning continuous steady implementation of the nuclear power projects in this country. However five post Chernobyl years have shown that the installed capacities of the Soviet NPPs increased only by 5GW. Basing on the most optimistic current estimations it can be said that by the turn of the century the total NPP capacity will not have reached even a third of 190 GW to which the Soviet nuclear program, adopted in the beginning of the 80s, was oriented. It should be pointed out that the cause of reduction in the program was not only canceling of the orders for new NPP construction but also stopped construction works even at the final stage of NPP erection. In the whole, research works, construction and extension of NPP were interrupted on 39 sites of total capacity 109 GW. Not going into a detailed analysis of the causes of this situation, it should be pointed out that deep economical and ecological prerequisites for maintenance and further development of the nuclear component in the fuel and energy balance of this country not only did not vanish but rather are growing in time in the forecasted economic situation

Last year, 2000, nuclear power plants were available for energy supply, respectively, in 18 countries all over Europe. In eight of the fifteen member countries of the European Union nuclear power plants have been in operation. A total of 218 plants with an aggregate net capacity of 172 259 MWe and an aggregate gross capacity of 181 642 MWe were in operation (31.12.2000; 215 plants, 180 067 MWe (gross), 172 259 MWe (net)). One unit, i.e. Temelin in the Czech Republic went critical for the first time and started test operation after having been connected to the grid. Temelin adds about 981 MWe (gross) and 912 MWe (net) to the electricity production capacity. Three units, Hinkley Point A1 and A2 in United Kingdom, and Chernobyl 3 in the Ukraine have been shut down during the year 2000. This means a loss of 1534 MWe gross capacity and 1420 MWe net capacity. Last year, 12 plants (31.12.2000: 11 plants) were under construction in Romania, Russia, Slovakia, the Czech Republic and the Ukraine, that is only in east european countries. In eight countries of the European Union 146 nuclear power plants have been operated with an aggregate gross capacity of 129 188 MWe and an aggregate net capacity of 123 061 MWe (31.12.2000: 144 plants, 128 613 MWe (gross), 122 627 MWe (net)). Net electricity production in 2000 in the EU amounts to approx. 818.8 TWh, which means a share of 35 per cent of the total production in the whole EU. Shares of nuclear power differ widely among the operator countries. The reach 76 per cent in France, 74 per cent in Lithuania, 57 per cent in Belgium and 47 per cent in the Ukraine. Nuclear power also provides an noticeable share in the electricity supply of countries, which operate no own nuclear power plants, e. g. Italy, Portugal and Austria. (orig.) [de

Mulching as a countermeasure for crop contamination within the 30 km zone of Chernobyl Nuclear Power Plant

The effect of mulch soil cover on crop contamination by 137 Cs was studied within the 30 km zone of Chernobyl Nuclear Power Plant. Experiments were performed with oats (Avena sativa) over a three year period. In 1992 soil surface was covered by a plastic net. In 1993 two straw mulch treatments were applied at a dose rate of 200 g m -2 using 137 Cs contaminated and clean straw, respectively. A similar mulch treatment was applied in 1994, and two mulch doses of clean straw were tested. Protection of the soil with a plastic net significantly increased crop yield and reduced crop contamination. When clean straw was used as a mulch layer, a significant decrease of about 30--40% in 137 Cs activity concentration was observed. Mulching with 137 Cs contaminated straw did not reduce crop contamination, probably due to an increase in soil available 137 Cs released from the contaminated mulch. Mulching has been shown to be an effective treatment both for reducing 137 Cs plant contamination and improving crop yield. Therefore, it can be considered as a potential countermeasure in a post-accident situation

Composition of Radioactive Aerosols in the Shelter Construction of the Chernobyl Nuclear Power Plant in 2000-2015

The results of the physicochemical studies of radioactive aerosols inside and outside the Shelter construction at the Arch construction stage of the Chernobyl Nuclear Power Plant (ChNPP) in 2000-2015 were presented. The dominant isotopes were shown to be cesium, strontium, americium, plutonium, and uranium. They are carried by disperse particles of 2-7 μm. In subreactor rooms, in particular, 012/7, the composition of aerosols is affected by the erosion of the fuel-containing mass formed in 1986. Submicron cesium carrier aerosols appear as a result of evaporation and condensation during fires and welding works. Radiocesium is a well-soluble component of aerosols, while plutonium isotopes are not readily soluble components. In several rooms, the contents of radon, thoron, and their daughter products exceeded the permissible values. In April-June 2011, the intake of radionuclides from the accident at the Japanese Fukushima-1 NPP, which had AMAD of 0.5 μm, was detected and tracked using Petryanov multilayer filters. The productivity of filtration units under the dusty conditions in the exclusion zone of ChNPP and in fogs and haze was investigated. Hydrophilic prefilters with 7-10 μm fibers were recommended.

Is the nuclear power an ethic alternative for the development?

Is the nuclear power an ethical alternative for the development of the energy sector? This is the question the authors try to answer. Nuclear power is subject to constant attacks from different opponent groups. They have managed to make negative public opinion, especially after the Chernobyl accident, which tends to minimise the important of that alternative. Unfortunately, nuclear professionals are also the subjects of that propaganda and even some of us are pessimistic about the future of our sector. The public will accept nuclear power if the producer guarantees that he is able to meet three conditions for the electricity supply: generation without risks for public or the environment, as cost-effective as possible and with high availability. In order to keep the confidence of general public for nuclear power, the authors, with total openness, compared the up-to-date power alternatives. The conclusion is, that for the next future, to avoid the global heating effect and to meet the constrains for a 'cleaner world', the humanity must to rely on nuclear power, besides other cleaner conventional alternatives, as ethical sources of energy.

Economic aspects of the social rehabilitation of nuclear power

1992-01-01

This article highlights the state of affairs regarding nuclear power in Russia at this time in the post-Chernobyl era. environmentalists and others are leveling criticisms at nuclear power stating that nuclear plants should be shutdown and preservation can offset the demands for electricity. The authors are advised to examine a new consensus for developing nuclear power, which could form the basis of a new program of social rehabilitation, and not a singular rejection of constructing new nuclear power plants. Public acceptance of nuclear power can be obtained only by resolving contradictions and by harmonizing the interests of all social groups and of all subjects of economic relationships, which in one way or another are connected to the financing and functioning of nuclear power plants (the local population, personnel, energy users, regional energy organizations, and local government). A strategy oriented to overall acceptance of nuclear power should consider intra area factors and also external economic environments: the choice of nuclear power plant location on the basis of careful and independent expertise with the use of rigid social-economic criteria and a sharp increase in the attention to human factors. Important features in changes in the economic environments are the transition to a marketplace economy, the reorientation of budget expenditures to social goals, and the expansion of regional economic independence. This requires a significant strengthening of the regional control of electrification and the creation of corresponding economic mechanisms

The nuclear power industry, when considered via statistical arguments, is far less dangerous than the average 'man in the street' in the UK perceives it to be. To support this assertion, an elementary analysis of the risk factors associated with commonplace hazards (e.g. road accidents and smoking) is presented. The radiological risks resulting from the Chernobyl nuclear power station accident, even in the most badly affected areas of the UK and at the times of highest intensity, were much less than those due to natural background radiation. Radioactive elements occur naturally in coal and are released as a result of combustion into the UK environment via flue gases and ash in significantly greater amounts than those from nuclear power stations.

Emergency preparedness lessons from Chernobyl

Emergency preparedness at nuclear power plants in the US has been considerably enhanced since the Three Mile Island accident. The Chernobyl accident has provided valuable data that can be used to evaluate the merit of some of these enhancements and to determine the need for additional improvements. For example, the USSR intervention levels of 25 rem and 75 rem for evacuation are contrasted with US Environmental Protection Agency protective action guides. The manner in which 135,000 persons were evacuated from the 30-km zone around Chernobyl is constrasted with typical US evacuation plans. Meteorological conditions and particulate deposition patterns were studied to infer characteristics of the radioactive plume from Chernobyl. Typical plume monitoring techniques are examined in light of lessons learned by the Soviets about plume behavior. This review has indicated a need for additional improvements in utility and government emergency plans, procedures, equipment, and training. 12 refs., 1 fig., 2 tabs

Finland has remarkable achievements in nuclear power. The existing four plants have some of the best operating records in the world - high capacity factors, low occupational doses and short refuelling outages. Public opinion was strongly turned against nuclear power after Chernobyl accident, and the previous government decided not to allow for the construction of a fifth nuclear unit during its period of reign. The opposition has however slowly been diminishing. According to the latest polls the opinion is almost balanced. Finnish power companies are going to file an application for a decision-in-principle to build a new plant to the new government appointed in April 1991. A readiness to start new construction project immediately after a positive political decision is made has been maintained during the intermediate period. Continuous research, development, modification and upgrading work provide important components of the good operational history of the Finnish nuclear power plants. Efforts have also been devoted to identifying possible new problems arising from the use of distributed digital C and I technology. The following a short description is summarizing recent activities related to the C and I-systems of the nuclear power plants. (author). 3 tab

The Nuclear Power Revival in Eastern Europe

International Nuclear Information System (INIS)

Bayou, Celine

2007-01-01

Far from traumatized by the April 1986 Chernobyl accident, the Central and Eastern European countries as well as the CIS are showing a growing interest in nuclear energy: this choice may be explained by increased energy demands and safer supply requirements but also by the battle against global warming. In effect, commitments made on limiting greenhouse gas emissions (particularly for the EU new member states) are becoming increasingly important as these countries return to growth. Thus, nuclear power seems to be a partial but secure means of not endangering the latter while adopting a more respectful stance vis-a-vis the environment. Thus, each country is coming out in favour of the civilian use of nuclear power: Russia has been reviving its nuclear program over the last few years, while countries obliged to close their decrepit or Soviet style power stations (Bulgaria, Slovakia, Lithuania, Slovenia, Armenia) have projects to build new ones. Those who possess reactors (the Czech Republic, Hungary, Romania, the Ukraine) are endeavouring to increase their potential, those which had hitherto no civilian nuclear facilities are now planning to build them (Belarus, Albania) or are contributing to projects in neighbouring countries (Estonia, Latvia, Poland). Within this context, the anti-nuclear argument has difficulty in finding a voice in the East

Attitudes towards nuclear power in Sweden: a history of ups and downs

Sokolowski, E.

1994-01-01

A brief description of Swedish nuclear program is given. The emphasis is stressed on the controversy aspects which haunted and paralyzed Swedish energy policy since early seventies. The political polarization and the TMI core-melt accident created instability in public opinion which led to announcing an advisory referendum in early 1980. The outcome of the referendum was 38.7% for the anti-nuclear line, 58.0% for a long term phase-out, and 3.3% blanks. After the referendum the energy issue faded into the background until the Chernobyl accident in April 1986 when a new wave of anti-nuclear sentiment swept over the country. But now public opinion recovered much faster than the politician had foreseen. The following facts contributed to that: electricity costs and unemployment had risen dramatically; the Chernobyl reactor had no relevance for the Swedish nuclear plants; nuclear power had met competition as a risk factor in opinion polls -only natural gas got a lower ranking. The politicians responded to the opinion change with a compromise: the early phase-out proposal was withdrawn in return for a development fund for renewable energy sources (bio-mass). Public acceptance of nuclear power culminated in 1990. After that there has again been a steady decline. As a whole, the future of the Swedish nuclear power program is uncertain. Yet in favour of it are the following: the new burdens on the economy due to the present recession; the lack of environmentally and economically acceptable alternatives; continued familiarization and education, together with improvement of safety.

Medical and radioecological consequences of the Chernobyl catastrophe in Western Europe

Full text: The catastrophe at the unit 4 of the Chernobyl Nuclear Power Plant in the Ukrainian SSR which occurred on 26 April 1986, was the most serious accident in the history of nuclear industry and the civil use of nuclear energy until this time. Initial explosions destroyed the reactor completely. During about 10 days, large amounts of radioactive material were released to the western part of Soviet Union as well as to all European countries. 25 years later in March 2011, the next nuclear disaster at a level of INES 7 occurred at the Fukushima Daiichi Site in Japan, where 4 reactor units were destroyed by explosions and nuclear melt down processes. Compared with Chernobyl, a larger amount of radioactivity was released in Fukushima. After Chernobyl, the majority of the radionuclide depositions affected the CIS countries. Due to continuously changing of wind directions and weather conditions during the 10 days of release of radioactivity, the radionuclide distribution and deposition was very inhomogeneous not only in the CIS countries, but even at far distances as in Germany, Scandinavia , the north of Scotland and many other countries. The former Secretary-General of the United Nations, Kofi Annan, has repeatedly placed particular emphasis on the fact that millions of people continue to be directly affected by the consequences of the Chernobyl accident, including acute suffering and continuing health disorders, and that this disaster is a matter of global concern. The most affected countries by the extent of radionuclide deposition show since years the incidence of cancer and other disorders of thyroid as well as many other serious health effects. After Chernobyl, nuclear disasters will happen again – as has been verified in Fukushima - in one of the more than 440 nuclear power stations worldwide. Most of them are located in areas with a population density several fold greater than in the case of Chernobyl. If we do not know the past, we will not be able to

As of August 1992 there were 433 power reactors operating in 35 countries and accounting for more than 15% of the world's production of electricity. In 1992, thirteen countries derived at least 25% of their electricity from nuclear units, with France leading at nearly 70%. In the same year, Canada produced about 16% of its electricity from nuclear units. Some 68 power reactors are under construction in 16 countries, enough to expand present generating capacity by close to 20%. No human endeavour carries the guarantee of perfect safety and the question of whether or not nuclear-electric generation represents an 'acceptable' risk to society has long been vigorously debated. Until the events of late April 1986, nuclear safety had indeed been an issue for discussion, for some concern, but not for alarm. The accident at the Chernobyl reactor in the USSR has irrevocably changed all that. This disaster brought the matter of nuclear safety back into the public mind in a dramatic fashion. This paper discusses the issue of safety in complex energy systems and provides brief accounts of some of the most serious reactor accidents which have occurred to date. (author). 7 refs

Chernobyl record. The definitive history of the Chernobyl catastrophe

Energy Technology Data Exchange (ETDEWEB)

Mould, R.F

2000-07-01

The contents of Chernobyl Record have taken 14 years to compile and this period of time was necessary to enable information to be released from Soviet sources, measurements to be made in the environment, for estimation of radiation doses and for follow-up of the health of population groups which had been exposed. This time frame also includes the 10th anniversary conferences and the completion of joint projects of the European Commission, Ukraine, Belarus and the Russian Federation. It has also enabled me to visit the power plant site, Chernobyl town and Pripyat relatively soon after the accident and also some 10 years later: December 1987 and June 1998. Without such visits some of the photographs in this Record could not have been obtained. Information is also contained in these pages of comparisons of various aspects of the Chernobyl accident with data from the Three Mile Island accident in the USA in 1979, the Hiroshima and Nagasaki atomic bombs, the highly contaminated Techa river area in the Urals in Russia and the accident in Tokaimura, Japan in 1999. The first two chapters are introductory in that they describe terminology which is necessary for an understanding of the remaining chapters. Chapters 3-6 describes the early events: including those leading up to the explosion and then what followed in the immediate aftermath. Chapters 7-8 describe the Sarcophagus and the past and future of nuclear power for electricity generation, including the future of the Chernobyl power station. Chapters 9-11 consider the radiation doses received by various populations, including liquidators, evacuees and those living on contaminated territories: and the contamination of milk by {sup 131}I, and the contamination of other parts of the food chain by {sup 137}Cs. Chapters 12-14 describe the environmental impact of the accident, as does chapter 11. Chapters 15-18 detail the long-term effects on health, including not only the incidence of cancer, but also of non

In the thesis the impact of the Chernobyl nuclear reactor accident on Finland was studied in three aspects: (1) the areal distribution of Chernobyl fallout in Finland was determined by measuring peat samples, (2) the behaviour of fallout radionuclides was investigated in the combustion of peat in power plants, and (3) the removal rates of fallout radionuclides on urban surfaces were resolved

Nuclear Power Project in Thailand

The Electricity Generating Authority of Thailand (EGAT), the main power producer in Thailand, was first interested in nuclear power as an electricity option in 1967 when the electricity demand increased considerably for the first time as a result of the economic and industrial growth. Its viability had been assessed several times during the early seventies in relation to the changing factors. Finally in the late 1970s, the proceeding with nuclear option was suspended for a variety of reasons, for instance, public opposition, economic repercussion and the uncovering of the indigenous petroleum resources. Nonetheless, EGAT continued to maintain a core of nuclear expertise. During 1980s, faced with dwindling indigenous fossil fuel resources and restrictions on the use of further hydro as an energy source, EGAT had essentially reconsidered introducing nuclear power plants to provide a significant fraction to the long term future electricity demand. The studies on feasibility, siting and environmental impacts were conducted. However, the project was never implemented due to economics crisis in 1999 and strong opposition by environmentalists and activists groups. The 1986 Chernobyl disaster was an important cause. After a long dormant period, the nuclear power is now reviewed as one part of the solution for future energy supply in the country. Thailand currently relies on natural gas for 70 percent of its electricity, with the rest coming from oil, coal and hydro-power. One-third of the natural gas consumed in Thailand is imported, mainly from neighbouring Myanmar. According to Power Development Plan (PDP) 2007 rev.2, the total installed electricity capacity will increase from 28,530.3 MW in 2007 to 44,281 MW by the end of plan in 2021. Significantly increasing energy demand, concerns over climate change and dependence on overseas supplies of fossil fuels, all turn out in a favor of nuclear power. Under the current PDP (as revised in 2009), two 1,000- megawatt nuclear

Nuclear power in societal flux. The renewal of nuclear power in Finland in the context of global concern over energy security

Litmanen, Tapio

2010-01-01

This paper will address nuclear power's relationship with societal flux. The history of nuclear power indicates that this type of technology is unusually to societal flux. Instability in nuclear power's societal status is created by the ambiguous nature of the technology itself, changing public opinion, the fluidity of political judgments, the flow of cultural meanings attaching to nuclear power and the unpredictability of media processing. Even though the risks of nuclear technology are highly regulated by the companies themselves and by the state and public administration, it remains capable of inflaming political debate and igniting controversy. One public opinion survey after another reveals how divisive nuclear power is. Unlike most other industrial activities nuclear power decision-making involves extraordinary levels of political consideration, societal processing and cultural valuation by stakeholders and the media. In order to illustrate the idea of societal flux, the paper will deal with major shifts in Finnish nuclear power policy since the 1950s, focusing particularly, however, on changes between 1986-2010. The recent changes in the country's nuclear power policy prove interesting having proceeded from a phase of rejection during the period 1986-1993, to a revival between 1994-2002 and renewal between 2002-2009. The rejection period ended in 1993 during which time the Parliament of Finland had rejected the further construction of nuclear power plants in the wake of the Chernobyl accident. In less than a decade, however, nuclear power policy changed. The revival period ended in 2001 as Parliament ratified a Decision in Principle for the final disposal of spent nuclear fuel and in 2002 for the construction of a new nuclear power plant unit, Olkiluoto 3. Characteristic of the ongoing renewal period is that in 2008-2009 the nuclear industry submitted three further applications for the construction of new NPP units. Thus Finland today has acquired a

The renaissance of Italian nuclear power

In the fifties Italy was an advanced country in terms of nuclear electricity but as a consequence of the Chernobyl accident Italy changed drastically its energy policy and closed definitely all its nuclear plants. Now in order to be less dependent on energy imports and to reduce its CO 2 emission, Italy has changed its mind and welcomes nuclear power in its future energy mix. The aim is to reach the following contributions for the production of electricity in 2030: 50% from fossil fuels, 25% from renewable energies and 25% from nuclear energy (13.000 MWe) and with a first reactor operating in 2020. The main actors of the renaissance of nuclear power in Italy are: -) ENEL (the second electricity producer in Europe), -) SOGIN, a company that is mainly in charge of the dismantling of nuclear plants, -) ENEA a state agency for the development of new technologies, energy and sustainable development, and -) companies working in the nuclear industry like ANSALDO. Various collaboration agreements have been signed between ENEL and EDF or between ENEA and CEA concerning staff training, nuclear safety or radioactive waste management. The main difficulties of this renaissance of the nuclear energy are to get the agreement of the national and local populations as well as that of the political class that is strongly marked by a division in 2 wings.

This report is an evaluation of the attitude of the Dutch government in response to the Chernobyl accident. It deals with measures taken by the government in order to minimize the (possible) effects, apparent shortcomings and how one has dealt with them, measures which can be taken at least by the Netherlands in case of a reactor accident given the presence of dozens of nuclear power plants in Europe. Good and less good aspects of the temporary organization are noted and some general recommendations are given. (Auth.)

Study of radioactive aerosols in the relocation zone and in the populated areas have been carried out for a number of years. The experiments on modelling resuspension were performed while conducting agricultural work. Nuclear track radiography and alpha spectrometry with radiochemical extraction of plutonium were used as analytical methods for the determination of the transuranium elements contents. The distributions of radioactive particles were obtained as to activity and sizes. Specific activity of 'hot particles' increases with decreasing diameter. In aerosols selected at a distance of more than 10 km from the Chernobyl NPP pure fuel particles with sizes of more than 5 {mu}m were not found. The activity of the finely dispersed fraction of aerosols, which is more dangerous when inhaled by the organism, is comparable with a total activity of large particles.

The Importance of Reliable Nuclear Power For Energy Supply

International Nuclear Information System (INIS)

Blix, Hans

1989-01-01

The severe accident at Chernobyl in 1986 caused a setback in public acceptance of nuclear power practically everywhere in the world. In some countries, the media even give the impression that nuclear power is on the way out worldwide, because of concerns about safety, radioactive waste disposal, and the risk of proliferation of nuclear weapons. Let me give you a more accurate picture of the situation. At the beginning of this year there were about 430 nuclear power reactors in operation in 26 countries around the world and they produced more than 16% of the world's electric energy. That amount of electricity is equal to the total amount of electric energy that was produced in the world in 1956. I mention this because, when we concentrate on the problems which nuclear power is facing, we tend to forget that among all the major energy sources? coal, oil, gas, hydro and nuclear- it is nuclear which has experienced the fastest rise in relative importance for the global energy supply. Its contribution to global energy supply has increased from just under 1% in 1974 to about 5% in 1987. On the positive side we can note the continuation of strong nuclear power programmes with construction starts in France and Japan, the start of construction at Sizewell B, which marks a new departure for nuclear power in the United Kingdom, and the orders for the Korean units 11 and 12

Twenty years of providing information on nuclear power. The experience of EDF

In France, the anti-nuclear protest movement became a real problem after 1968, as new sites were sought. Initially, information on nuclear power involved communication by the entities responsible for building the plants. Once Government officials and politicians overcame their initial hesitation, their support, which underscores the continuity of France's energy policy, came to play a major role in the public acceptance of nuclear power. Electricite de France (EDF) then had to master the art of informing and communicating with the public. The change in the parliamentary majority in 1981 did not call into question the nuclear programme, and new plants were commissioned with relative ease. The situation changed dramatically with the Chernobyl disaster. It therefore became vital to establish an efficient structure for crisis communications, and transparency became crucial. The focus shifted from launching new plants to operating existing facilities and restoring public confidence. While not neglecting the general public, the emphasis was on certain strategic segments of the population, notably teachers and health care professionals. Advertising campaigns are today aimed at certain segments of the public, whose opinion could well shift in favour of nuclear power. Lastly, EDF, as power plant operator, has to realize the importance of providing information on nuclear waste. Starting from a strategic policy of informing politicians and senior decision makers, in 1974 EDF began to focus on providing information that would 'educate' the public. This information was issued via technicians who had no specific training in communications techniques. In addition to the need to explain and justify its projects, EDF had to adopt a policy of transparency, and to dispense with the esoteric language of specialists and their preference for secrecy. After Chernobyl, EDF's managers made communications with the 'outside world' an integral part of their jobs. Nuclear information became a

Fire protection in nuclear power plants

International Nuclear Information System (INIS)

1992-01-01

The Code on Design (Safety Series 50-C-D (Rev. 1)) within the NUSS (Nuclear Safety Standards) programme of the IAEA points out the necessity of measures for protecting plant items which are important to safety against fires of internal and external origin. Experience of the past two decades in the operation of nuclear power plants and modern analysis techniques confirm that fire may be a real threat to nuclear safety and should receive adequate attention from the beginning of the design process throughout the life of the plant. Within the framework of the NUSS programme, a Safety Guide on fire protection had therefore been developed to enlarge on the general requirements given in the Code. Since its first publication in 1979, there has been considerable development in protection technology and analysis methods and after the Chernobyl accident it was decided to revise the existing Guide. The present Safety Guide is intended to advise designers, safety assessors and regulators on the concept of fire protection in the design of nuclear power plants and on recommended ways of implementing the concept in some detail in practice.

Innovative Modelling Approach of Safety Culture Assessment in Nuclear Power Plant

International Nuclear Information System (INIS)

Ahn, N.

2016-01-01

A culture is commonly defined as the shared set of norms and values that govern appropriate individual behavior. Safety culture is the subset of organizational culture that reflects the general attitude and approaches to safety and risk management. While safety is sometimes narrowly defined in terms of human death and injury, we use a more inclusive definition that also considers mission loss as a safety problem and is thus applicable to nuclear power plants and missions. The recent accident reports and investigations of the nuclear power plant mission failures (i.e., TMI, Chernobyl, and Fukushima) point to safety cultural problems in nuclear power plants. Many assessment approaches have been developed by organizations such as IAEA and INPO based on the assessment of parameters at separate levels — individuals, groups, and organizations.

Comparison of the Chernobyl and Fukushima nuclear accidents: a review of the environmental impacts.

The environmental impacts of the nuclear accidents of Chernobyl and Fukushima are compared. In almost every respect, the consequences of the Chernobyl accident clearly exceeded those of the Fukushima accident. In both accidents, most of the radioactivity released was due to volatile radionuclides (noble gases, iodine, cesium, tellurium). However, the amount of refractory elements (including actinides) emitted in the course of the Chernobyl accident was approximately four orders of magnitude higher than during the Fukushima accident. For Chernobyl, a total release of 5,300 PBq (excluding noble gases) has been established as the most cited source term. For Fukushima, we estimated a total source term of 520 (340-800) PBq. In the course of the Fukushima accident, the majority of the radionuclides (more than 80%) was transported offshore and deposited in the Pacific Ocean. Monitoring campaigns after both accidents reveal that the environmental impact of the Chernobyl accident was much greater than of the Fukushima accident. Both the highly contaminated areas and the evacuated areas are smaller around Fukushima and the projected health effects in Japan are significantly lower than after the Chernobyl accident. This is mainly due to the fact that food safety campaigns and evacuations worked quickly and efficiently after the Fukushima accident. In contrast to Chernobyl, no fatalities due to acute radiation effects occurred in Fukushima. © 2013.

Results of the environmental programmes for monitoring radioactive contamination around Finnish nuclear power plants in 1987 are reported. Fallout from the Chernobyl accident, which took place in April 1986, was still dominating the artificial radiation situation in Finland. Thus, large amounts of 137 Cs and other long-lived fallout nuclides predominated in the environmental samples taken in the vicinity of nuclear power plants. The extremely small airborne releases from Finnish nuclear power plants were almost totally covered by fallout nuclides. The somewhat higher aquatic releases were easier to distinguish, and it was possible to follow their spread in the marine environment. The contribution of locally discharged nuclides to radiation doses of the population was insignificant

The present study entitled ''Emergency Response and Nuclear Risk Governance: nuclear safety at nuclear power plant accidents'' deals with issues of the protection of the population and the environment against hazardous radiation (the hazards of nuclear energy) and the harmful effects of radioactivity during nuclear power plant accidents. The aim of this study is to contribute to both the identification and remediation of shortcomings and deficits in the management of severe nuclear accidents like those that occurred at Chernobyl in 1986 and at Fukushima in 2011 as well as to the improvement and harmonization of plans and measures taken on an international level in nuclear emergency management. This thesis is divided into a theoretical part and an empirical part. The theoretical part focuses on embedding the subject in a specifically global governance concept, which includes, as far as Nuclear Risk Governance is concerned, the global governance of nuclear risks. Due to their characteristic features the following governance concepts can be assigned to these risks: Nuclear Safety Governance is related to safety, Nuclear Security Governance to security and NonProliferation Governance to safeguards. The subject of investigation of the present study is as a special case of the Nuclear Safety Governance, the Nuclear Emergency governance, which refers to off-site emergency response. The global impact of nuclear accidents and the concepts of security, safety culture and residual risk are contemplated in this context. The findings (accident sequences, their consequences and implications) from the analyses of two reactor accidents prior to Fukushima (Three Mile Iceland in 1979, Chernobyl in 1986) are examined from a historical analytical perspective and the state of the Nuclear Emergency governance and international cooperation aimed at improving nuclear safety after Chernobyl is portrayed by discussing, among other topics, examples of &apos

Hiroshima, Chernobyl, Fukushima Daiichi are the well known sad milestones on the path toward a broad development of nuclear energy. They are so well known that they have blurred certainly for long in a very unfair way the positive image of nuclear energy in the public eye. The impact of the media appetite for disasters favours the fear and puts aside all the achievements of nuclear sciences like nuclear medicine for instance and all the assets of nuclear power like the quasi absence of greenhouse gas emission or its massive capacity to produce electricity or heat. The unique solution to enhance nuclear acceptance is the reduction of the fear through a better understanding of nuclear sciences by the public. (A.C.)

The accident at the Chernobyl NPP (nuclear power plant) was the most serious ever to have occurred in the history of nuclear energy. The consumption of contaminated foodstuffs in affected areas was a significant source of irradiation for the population. A wide range of different countermeasures have been used to reduce exposure of people and to mitigate the consequences of the Chernobyl accident for agriculture in affected regions in Belarus, Russia and Ukraine. This paper for the first time summarises key data on countermeasure application over twenty years for all three countries and describes key lessons learnt from this experience. (review)

Exploding Chernobyl myths

Arnott, D.

1991-01-01

Misconceptions about the way thermal reactors really work, and the use of misleading terminology, have allowed the western nuclear industry to claim that the accident at the RBMK (water cooled, graphite moderated) type reactor at Chernobyl would not be possible in western type pressurized water reactors. The author contends that control of thermal reactors is only possible because a small but consistent fraction of the secondary neutrons are delayed. If the delayed neutron reaction is overridden by the prompt neutron reaction, control is irretrievably lost and a nuclear explosion, such as at Chernobyl, results. Parallels between the PWR and RBMK are drawn. The consequences of the Chernobyl explosion are discussed and the question is asked: can any combination of circumstances, however improbable, produce a prompt neutron explosion in any western reactors?

1991-01-01

The Chernobyl accident has greatly intensified the readiness for international cooperation on problems of reactor safety and for exchanges of operating experience. That accident was more than a regional event. If all psychological and political consequences are taken into account, its international significance is apparent. In principle, it demonstrated not the lack of safety of nuclear power plants generally, but rather that of the Soviet RBMK reactor line, which would not have been licensed in any Western country because of its inherent unsafety. In the long run, the worldwide acceptance of nuclear power can be regained and stabilized only by an open dialog and by international exchanges of experience. The pronounced growth of the world's population requires energy policy to think beyond national frontiers. The rising energy requirement permits of no other decision than to exploit all technically feasible and economically viable as well as ecologically tolerable sources of energy. This includes nuclear power as well as solar energy. (orig.) [de

Nuclear power: An evolving scenario

ElBaradei, Mohamed

2004-01-01

The past two years have found the IAEA often in the spotlight - primarily because of our role as the world's 'nuclear watchdog', as we are sometimes referred to on the evening news. The most visible, and often controversial, peaceful nuclear application is the generation of electricity, the focus of this article largely from a European perspective. At the end of last year there were 440 nuclear power units operating worldwide. Together, they supply about 16% of the world's electricity. That percentage has remained relatively steady for almost 20 years. Expansion and growth prospects for nuclear power are centred in Asia. Of the 31 units under construction worldwide, 18 are located in India, Japan, South Korea and China, including Taiwan. Twenty of the last 29 reactors to be connected to the grid are also in the Far East and South Asia. That is probably more active construction than most Europeans would guess, given how little recent growth has occurred in the West. For Western Europe and North America, nuclear construction has been a frozen playing field - the last plant to be completed being Civaux-2 in France in 1999. That should raise a question: with little to no new construction, how has nuclear power been able to keep up with other energy sources, to maintain its share of electricity generation? Interestingly enough, the answer is tied directly to efforts to improve safety performance. The accident at Chernobyl in 1986 prompted the creation of the World Association of Nuclear Operators (WANO), and revolutionized the IAEA approach to nuclear power plant safety. Some analysts believe the case for new nuclear construction in Europe is gaining new ground, for a number of reasons: efforts to limit greenhouse gas emissions and reduce the risk of climate change; security of energy supply; Comparative Public Health Risk; different set of variables when choosing Each country's and region energy strategy. Looking to the future, certain key challenges are, of direct

The advantages of nuclear power and the mistakes that cause the opposition against it on the example of the history of the Bulgarian nuclear power sector are considered in a polemical manner. Four WWER 440/230 and two WWER 1000 units have been put into operation in Kozloduj NPP in the period 1974 - 1993. Before 1991, however, safety operation criteria were compromised numerous times and the atmosphere of secrecy, self-complacency and the series of absurdities about the Chernobyl accident were clearly used by the opponents of nuclear energy. Now the attitude towards nuclear power is changing for the better. Much progress has been made in recovering the nuclear power sector under complicated economic and political conditions. The role of NPP as an anti-inflation factor, an element providing the national security, a stimulator of industry and infrastructure, and an ecological salvation factor, is stressed. (I.M.)

The role of NPP as an anti-inflation factor, an element providing the national security, a stimulator of industry and infrastructure, and an ecological salvation factor, is stressed. (I.M.).

Observations on the Chernobyl Disaster and LNT.

The Chernobyl accident was probably the worst possible catastrophe of a nuclear power station. It was the only such catastrophe since the advent of nuclear power 55 years ago. It resulted in a total meltdown of the reactor core, a vast emission of radionuclides, and early deaths of only 31 persons. Its enormous political, economic, social and psychological impact was mainly due to deeply rooted fear of radiation induced by the linear non-threshold hypothesis (LNT) assumption. It was a historic event that provided invaluable lessons for nuclear industry and risk philosophy. One of them is demonstration that counted per electricity units produced, early Chernobyl fatalities amounted to 0.86 death/GWe-year), and they were 47 times lower than from hydroelectric stations ( approximately 40 deaths/GWe-year). The accident demonstrated that using the LNT assumption as a basis for protection measures and radiation dose limitations was counterproductive, and lead to sufferings and pauperization of millions of inhabitants of contaminated areas. The projections of thousands of late cancer deaths based on LNT, are in conflict with observations that in comparison with general population of Russia, a 15% to 30% deficit of solid cancer mortality was found among the Russian emergency workers, and a 5% deficit solid cancer incidence among the population of most contaminated areas.

Generic implications of the Chernobyl accident

Sege, G.

1989-01-01

The US Nuclear Regulatory Commission (NRC) staff's assessment of the generic implications of the Chernobyl accident led to the conclusion that no immediate changes in the NRC's regulations regarding design or operation of US commercial reactors are needed. However, further consideration of certain issues was recommended. This paper discusses those issues and the studies being addressed to them. Although 24 tasks relating to light water reactor issues are identified in the Chernobyl follow-up research program, only four are new initiatives originating from Chernobyl implications. The remainder are limited modifications of ongoing programs designed to ensure that those programs duly reflect any lessons that may be drawn from the Chernobyl experience. The four new study tasks discussed include a study of reactivity transients, to reconfirm or bring into question the adequacy of potential reactivity accident sequences hitherto selected as a basis for design approvals; analysis of risk at low power and shutdown; a study of procedure violations; and a review of current NRC testing requirements for balance of benefits and risks. Also discussed, briefly, are adjustments to ongoing studies in the areas of operational controls, design, containment, emergency planning, and severe accident phenomena

In the aftermath of the accident at the Chernobyl nuclear power station in the Soviet Union, nuclear power plant operators throughout the world came together in May 1989 to form the World Association of Nuclear Operators (WANO). When it became clear that the operators of plants of an early design supplied by the USSR needed assistance in the upgrading of the safety of these units, WANO was uniquely placed to assist and facilitate in this. In July 1990, WANO took the decision to form a special project to assist the operators of the VVER 440/230 plants in their efforts to increase the safety standards for these units. The work performed by this special project team is described

Photography and nuclear catastrophe. The visual representation of the occurrences in Hiroshima/Nagasaki and Chernobyl

The dissertation project seeks to analyse the photographic positions that deal with the atomic bomb attacks on Hiroshima and Nagasaki and the accident of the nuclear power plant in Chernobyl. This focus includes press photographs of the events as well as artistic, documentary and touristic images that take an approach towards the disasters often years after and hereby form iconographic or material references to the events. The study reveals central strategies for photographic images of atomic catastrophes, be they of military or civil nature. It is the inability to visualize non-visible nuclear rays or the complexity of processes on an atomic level that has turned out to be crucial. This incapacity of making images, a paradigm of invisibility, substantially coins the cultural role of the events. The question of how a society deals with these abstract potentials of nuclear technology has turned out to be always anew of high relevance in regard to ecological, social and technological policies of images.

Health consequences of Chernobyl: the New York Academy of Sciences publishes an antidote to the nuclear establishment's pseudo-science.

2010-01-01

In February 2010, the New York Academy of Sciences published the most complete and up-to-date collection of evidence, from independent, scientific sources all over the world, on the health and environmental consequences of the Chernobyl accident. For 24 years, through a high-level, internationally coordinated cover-up of the world's most serious industrial accident, the nuclear lobby has deprived the world of a unique and critically important source of scientific information. The International Atomic Energy Agency (IAEA), mouthpiece of the nuclear establishment, has coordinated the cover-up through the dissemination and imposition of crude pseudo-science. Regrettably, the World Health Organization, a U.N. agency on which the world's people rely for guidance, is subordinate to the IAEA in matters of radiation and health, has participated in the cover-up, and stands accused of non-assistance to populations in danger. The new book on Chernobyl makes available huge amounts of evidence from independent studies undertaken in the affected countries, unique and valuable data that have been ignored by the international health establishment. This comprehensive account of the full dimensions of the catastrophe reveals the shameful inadequacy of current international assistance to the affected populations. It also demonstrates, once more, that future energy options cannot include nuclear power.

The long-term effects of the ionizing radiation on the bioelectric brain activity in the Chernobyl nuclear disaster liquidators with discirculatory encephalopathy and arterial hypertension were studied. We examined 195 male patients, aged from 30 to 65 years, with the clinical presentations of discirculatory encephalopathy, using electroencephalography: 105 patients were liquidators of the Chernobyl nuclear disaster (the main group) and 90 patients had no radiation anamnesis (the comparison group). It has been found that the development of discirculatory encephalopathy in liquidators of the Chernobyl nuclear disaster is mainly associated with the dysfunction of diencephalic and cortical structures. The specificity of the neurofunctional brain abnormalities in liquidators with discirculatory encephalopathy is characterized by the predominance of the low-amplitude and low-frequency alpha-activity or by the lack of alpha-rhythm and by its substitution for the high-frequency beta-rhythm with the presence of theta- and delta-activity and by the more significant flatness of the alpha-rhythm zonation. The presence of the radiation factor in the past history is correlated with the failure of the bioelectric brain activity in the alpha band (r=0.42) that increases risk of abnormal changes by a factor of 10 (pChernobyl nuclear disaster in the post-radiation period during the development of discirculatory encephalopathy and arterial hypertension.

The accident at the Chernobyl NPP (nuclear power plant) was the most serious ever to have occurred in the history of nuclear energy. The consumption of contaminated foodstuffs in affected areas was a significant source of irradiation for the population. A wide range of different countermeasures have been used to reduce exposure of people and to mitigate the consequences of the Chernobyl accident for agriculture in affected regions in Belarus, Russia and Ukraine. This paper for the first time summarises key data on countermeasure application over twenty years for all three countries and describes key lessons learnt from this experience. (review)

The enduring lessons of Chernobyl. International conference of the Chernobyl Forum, 6 September 2005, Vienna, Austria

The April 1986 accident at the Chernobyl nuclear power plant remains a defining moment in the history of nuclear energy. The lessons of this tragedy are interwoven with a recurrent theme: namely, the importance of international cooperation. With its recently released document - entitled 'Chernobyl's Legacy' - the Chernobyl Forum has solidly reinforced that theme. The major impacts of Chernobyl fall into three categories: the physical impacts, in terms of health and environmental effects; the psychological and social impacts on the affected populations; and the influence of the accident on the nuclear industry worldwide. The physical impacts mark Chernobyl as the site of the most serious nuclear accident in history. The explosions that destroyed the Unit 4 reactor core released a cloud of radionuclides that contaminated large areas of Europe and, in particular, Belarus, the Russian Federation and Ukraine. Hundreds of thousands of people were exposed to substantial radiation doses, including workers from all three of these countries who participated in efforts to mitigate the consequences of the accident. The definitive numbers compiled in the Chernobyl Forum report are sobering: the 50 emergency rescue workers who died from acute radiation syndrome and related illnesses; the 4000 children and adolescents who contracted thyroid cancer - 9 of whom also died; and the hundreds of thousands of hectares of cropland, forests, rivers and urban centres that were contaminated by environmental fallout. But as severe as these impacts were, the situation was made even worse by conflicting information and vast exaggerations - in press coverage and pseudo-scientific accounts of the accident - reporting, for example, fatalities in the tens or hundreds of thousands. The psychological and social impacts were also devastating. Over 100 000 people were immediately evacuated, and the total number of evacuees from contaminated areas eventually reached 350 000. While some of these

Nearly 20 years after the Chernobyl nuclear power plant (NPP) accident, many questions remained unanswered regarding the health, environmental, and socio-economic consequences of the disaster. The individuals and countries most affected had yet to obtain a clear scientific consensus on the impact of the accident and authoritative answers to outstanding questions. To fill this void and to promote better understanding and improved measures to deal with the impacts of the accident, the Chernobyl Forum was established in 2003. The Chernobyl Forum is an initiative of the IAEA, in cooperation with the WHO, UNDP, FAO, UNEP, UN-OCHA, UNSCEAR, the World Bank and the governments of Belarus, the Russian Federation and the Ukraine. The Forum was created as a contribution to the United Nations' ten-year strategy for Chernobyl, launched in 2002 with the publication of Human Consequences of the Chernobyl Nuclear Accident - A Strategy for Recovery. To provide a basis for achieving the goal of the Forum, the IAEA convened an expert working group of scientists to summarize the environmental effects, and the WHO convened an expert group to summarize the health effects and medical care programmes in the three most affected countries. The information presented in this document and in the two full expert group reports has been drawn from scientific studies undertaken by the IAEA, WHO, UNSCEAR and numerous other authoritative bodies. In addition, UNDP has drawn on the work of eminent economists and policy specialists to assess the socio-economic impact of the Chernobyl accident, based largely on the 2002 UN study as above

The distribution of iodine in the vicinity of nuclear power plants: the impossibility of ''banalizing'' nuclear power

Duchene, F.; Ferrand, V.

Despite the controversial dimension of civilian nuclear facilities, the recent distribution of iodine in the vicinity of nuclear power plants in France brought little response from the populations concerned. Could it be that nuclear power plants today are looked upon as ordinary factories by those who live near them? Could it be that the risks they incur have become 'banal'? A qualitative survey conducted in the area around the Bugey nuclear power plant, near Lyons, has provided food for further thought on the matter. The building of the plant in 1965 brought about profound changes in the host territory which has gone from a rural way of life to the era of industry and peri-urbanization. Yet the isolation in which employees of the facility were long seen to live, or the considerable amounts of tax it provides, particularly to the village which hosted it, have meant that the nuclear site has always kept its own particular status, despite the creation of chemicals industries in the surrounding area. The Chernobyl accident was a blow to the reassuring discourse thus for exuded by the EDF The testimony of the local people reveals the construction of different forms of 'symbolic protection', which were themselves to be shattered by the iodine distribution operation. By 'backing' focused communication rather than information, EDF merely sustained the confusion surrounding an industrial facility that remains somewhat out of the ordinary. (authors)

First steps of Poland in the nuclear power industry

Poland appears as a new-comer in the domain of nuclear power but in fact previous projects of nuclear power plants existed but were abruptly stopped in the afterwards of Chernobyl. Today almost 90% of the electricity produced in Poland comes from the combustion of coal and lignite. In january 2009 the Polish government decided to include nuclear power in the energy mix with an aim of a 15% share of the electricity production in 2030 and with the first nuclear plant operating in 2020. The path toward this aim is marked out as following. 2009-2010: drawing up of the legal frame, creation of the nuclear safety authority, drawing up of the list of potential sites, and launching of the public debate. 2011-2013: selection of the first site, of the pool of investors, of the reactor technology and the signature of the contract for the first plant. 2014-2015: obtention of the administrative agreements, elaboration of the technical project. 2016-2020: construction of the plant. The polish public opinion favours nuclear energy and there is a kind of competition between different regions to home nuclear power plants. In 2010 Poland signed various collaboration agreements with the Usa, France and South-Korea. Polish authorities are studying the pros and cons of the EPR (EDF - Areva), ABWR (GE/Hitachi) and AP1000 (Westinghouse) reactors. (A.C.)

FAPIG organizes a visit to nuclear power station in every November. It is an object that visitors acquire the correct knowledge of nuclear power by looking at the various facilities in the nuclear power stations. The paper showed the analytical results of questionnaire executed at organized visits to the Kashiwazaki-Kariwa nuclear power station. The visitors were 18 women. The questionnaire was carried out by the same problems before and after seminar and a conducted tour. Their impressions and opinions and the changes are analyzed. The speakers used easy words, video, OHP, pamphlet and experimental equipment. These means showed very good results to visitors. The seminar had very large effect on just recognition of safety and need of it. The change of answer proved from 3 to 6 of need and from 0 to 7 of safety of it. Nine members indicated good understanding of seminar content. The interested items in the seminar were measurement of radiation, effects of radiation, reason of decreasing average life, Chernobyl accident, difference between nuclear power and atomic bomb and nuclear power dose not generate carbon dioxide and recycle plutonium after nuclear fission of uranium.

1995-01-01

The dynamics of radioactive contamination of aquatic ecosystems (1986-1990) is considered on the basis of observational data in the near and distant zones of the Chernobyl fallout (the Chernobyl Nuclear Power Plant (CNPP) cooling pond, the Pripyat River, the Dnieper reservoirs, and the Kopor inlet of the Gulf of Finland). Radionuclide accumulation in aquatic biota is analyzed. The results obtained indicate that the radioecological conditions in the water bodies under investigation were in a state of non-equilibrium over a long period of time following the Chernobyl accident. Reduction in the 137 Cs concentration proceeded slowly in most of the aquatic ecosystems. The effect of trophic levels which consisted of increased accumulation of radiocaesium by predatory fish was observed in various parts of the contaminated area. (author)

1997-01-01

Following numerous national and international studies conducted on the overall impact of the 1986 Chernobyl nuclear power plant disaster, decision-makers of the affected countries have oriented their efforts on environmental clean-up and population safety. They have focused on activities leading to a better understanding of radionuclide contamination and to the development of effective environmental rehabilitation programs. Initial developments involved the use of domestic USSR technologies consisting of mainframe IBM computers and DEC minicomputers. Later, personal computers with imported software packages were introduced into the decision-making process. Following the breakup of the former USSR, the Ministry of Chernobyl was created in Ukraine in 1991. One of the Ministry's mandate was the elimination of the environmental after-effects of the Chernobyl disaster

Alvarenga, Marco Antonio Bayout; Rabello, Sidney Luiz

2011-01-01

Severe accidents are the result of multiple faults that occur in nuclear power plants as a consequence from the combination of latent failures and active faults, such as equipment, procedures and operator failures, which leads to partial or total melting of the reactor core. Regardless of active and latent failures related to the plant management and maintenance, aspects of the latent failures related to the plant design still remain. The lessons learned from the TMI accident in the U.S.A., Chernobyl in the former Soviet Union and, more recently, in Fukushima, Japan, suggest that severe accidents must necessarily be part of design-basis of nuclear power plants. This paper reviews the normative basis of the licensing of nuclear power plants concerning to severe accidents in countries having nuclear power plants under construction or in operation. It was addressed not only the new designs of nuclear power plants in the world, but also the design changes in plants that are in operation for decades. Included in this list are the Brazilian nuclear power plants, Angra-1, Angra-2, and Angra-3. This paper also reviews the current status of licensing in Brazil and Brazilian standards related to severe accidents. It also discusses the impact of severe accidents in the emergency plans of nuclear power plants. (author)

Since the worlds first nuclear reactor major breakthrough in December 02, 1942, the nuclear power industry has undergone tremendous development and evolution for more than half a century. After surpassing moratorium of nuclear power plant construction caused by catastrophic accidents at Three-mile island (1979) and Chernobyl (1986), today, nuclear energy is back on the policy agendas of many countries, both developed and developing, signaling nuclear revival or nuclear renaissance. Selection of suitable nuclear power technology has thus been subjected to primary attention. This short paper attempts to draw preliminary technology assessment for the first nuclear power reactor technology for Malaysia. Methodology employed is qualitative analysis collating recent finding of tnb-kepco preliminary feasibility study for nuclear power program in peninsular malaysia and other published presentations and/or papers by multiple experts. The results suggested that pressurized water reactor (PWR) is the prevailing technology in terms of numbers and plant performances, and while the commercialization of generation IV reactors is remote (e.g. Not until 2030), generation III/ III+ NPP models are commercially available on the market today. Five (5) major steps involved in reactor technology selection were introduced with a focus on introducing important aspects of selection criteria. Three (3) categories for the of reactor technology selection were used for the cursory evaluation. The outcome of these analyses shall lead to deeper and full analyses of the recommended reactor technologies for a comprehensive feasibility study in the near future. Recommendations for reactor technology option were also provided for both strategic and technical recommendations. The paper shall also implore the best way to select systematically the first civilian nuclear power reactor. (Author)

Environmental assessment of the Chernobyl releases in China

Since Chernobyl accident, China has rapidly developed a program of emergency preparedness for nuclear accidents that the institute of radiation protection assumes the responsibility together with other institutions. For the nuclear power plants in Qinshan and in Daya Bay, a series of emergency preparedness, including the investigation of conditions and feasibility of some principal protective measures are being carried out. The research program includes atmospheric transfer and dispersion, modelling analysis of accident consequence assessment and development of a computer software system for accident consequence prediction. The strategy of China is to well organize all resources and to broaden the international cooperation. The drafting of national emergency regulations and technical guides and the establishment of specialized technical teams are in progress. In China, the accident consequence assessment is based on the specialist experiences from transfer of radioactive effluents in the atmosphere, in water and in ecological system. On May 1986 environmental assessment of the Chernobyl releases in China and environmental monitoring were carried out. Radio-nuclides released from the Chernobyl accident were detectable in all parts of country but the concentrations were very low. The results of the environmental monitoring have been presented. 7 figs., 11 tabs. (author)

On symbiotic nuclear power: a test for feasibility of comprehensive national energy policy of Japan

This paper examines ambivalent attitudes of the Japanese toward nuclear power and shows that despite great benefits nuclear power plants may bring to local governments and people, the Japanese have become more sensitive to risks of nuclear related facilities than to their benefits in a post Chernobyl period. In this light, the usefulness and limitations of economic incentives are analyzed. Third, the importance of particular institutional arrangements is discussed with respect to development 'symbiotic' schemes for nuclear power plants and people in neighboring communities. These 'symbiotic' schemes have dual purposes: to make a wider and more flexible use of the site space for developing local industries, and to raise the quality of life by improving the socio-economic infrastructure and social welfare. 6 refs., 1 fig

Nuclear Issues in a Non-nuclear Country Media

The absence of nuclear power program in a given country does not mean that the nuclear option is not discussed. Greenhouse effect is a global phenomenon, thus each and every factor enabling the reduction of CO 2 emissions has to be examined. Not a single NPP is in operation in Poland and this will be so for the nearest dozen years. But the discussion over political decisions to delay the possible NPP construction beyond 2020 continues. In the country whose electricity in 95% comes from coal, the clean (from the greenhouse effect viewpoint) nuclear power makes an attractive solution for many experts. This paper presents Polish debates on the electricity production environmental impacts, which are followed by the media. Unfortunately, a favorite subject of Polish media is still Chernobyl accident, but presented in an exaggerated and often untrue way. This one-sided fear campaign has been interrupted recently by a publication calling the reports on Chernobyl victims a biggest bluff of XX century. This paper presents some examples of nuclear campaigns in the media, e.g. the issues of depleted uranium ammunition, Temelin NPP commissioning and the transit of fresh nuclear fuel for this facility through Poland, radiation accident in one of Polish hospitals, possible terrorist attacks on nuclear facilities, UNSCEAR report on Chernobyl accident health impacts. It remains to be seen how the hundreds of publications appearing each week will shape public attitudes towards nuclear power in Poland. (author)

Public Acceptance on Nuclear Power: A Strategic Need to Shift to 5Ps (Politicians, Policy Makers, Professionals, Public and Press) Acceptance on Nuclear Power

Business should not be as usual in formulating strategies and plans to enhance awareness regarding the benefits of nuclear power as an option for energy mix. Although, presently 435 nuclear power reactors in operation in 30 countries are delivering cost competitive electricity to consumers, creating significant job, investment and business opportunities, supporting enterprises, contributing significantly to these nations economic growth, however these positive impacts and benefits have not be sufficiently transmitted to the various stakeholders and population, who have until recently only received unbalanced views and news from an uninformed press. Negative and generally unbalanced press coverage of isolated nuclear incidents and accidents such as TMI, Chernobyl and most recently Fukushima has resulted in public protests to nuclear power, contributing to several nuclear power programmes being delayed or not able to take off. This situation is further exacerbated by uninformed politicians and policy makers who have the influence but were not able to harness their positions to assure the public due to lack of knowledge regarding the economic and social benefits of nuclear power. As the challenges to the nuclear industry presently also include ageing nuclear professionals, lack of updates regarding business and financing opportunities to business and financing professionals, thus the benefits of career, business and financing opportunities must also be disseminated to these Professionals. This paper aims to highlight the fundamental need to expand present Public Awareness Programme to become the 5Ps (Politicians, Policy makers, Professionals, Public and Press) Awareness Programme on Nuclear Power.

An earthquake at their locations could seriously damage these plants and could result in Chernobyl-like consequences on the environment. There is an ongoing program to reinforce these plants using conventional piecemeal methods. A newly developed seismic protection strategy called 'base isolation' or 'seismic isolation', widely used in the United States to retrofit existing buildings, is recommended as an economical, technically superior, and more effective solution - where applicable - to make these nuclear power plants capable of resisting seismic forces.

Three Mile Island, Bhopal and Chernobyl: causes and consequences

International Nuclear Information System (INIS)

Jovanovich, J.

2003-01-01

Since 1970's worldwide criticisms of nuclear power have been so strong that in many countries nuclear power has been outlawed. At Kyoto, scientists and politicians working together have designed a Protocol where the role of nuclear power in reducing CO2 emissions was completely ignored. One of the reasons for this, probably the most important one, is the general perception that nuclear power is unacceptably dangerous and that world can live without it. Both perceptions are, of course, incorrect. Some twenty years ago, as a physicist, not being part of 'nuclear establishment', I became interested in these two issues. Since then, as explained in a number of my publications, I have come to a firm conclusion that (a) nuclear power on the world scale is an essential energy source, whether we like it or not, and (b) that nuclear power is a very safe technology, probably the safest of all technologies the modem industrialized world has. To illustrate this last statement, in this paper I compare causes and consequences of two largest nuclear accidents, TMI and Chernobyl, with Bhopal accident, probably the largest accident that chemical technology has ever produced.

Deposition of radioactive products escaping into the atmosphere for a long time from the Chernobylsk-4 reactor resulting in residual radioactive contamination of the region at a distance of up to 100 km from the nuclear power plant is considered. The suggested model may be used for estimation of the possible scope of nuclear danger in the regions of nuclear power plants and creation of conditions ensuring safety of the population at possible accidents. The following topics are developed: height of elevation and conditions of radionuclide transfer in the atmosphere; dynamics of release and dispersive composition of radioactive products; calculations of radiation levels at a close trace [fr

One decade after Chernobyl: summing up the consequences of the acci dent

Over the past year a series of international conferences have been held to review the effects and impact of the nuclear accident at the Chernobyl nuclear power plant on 26 April 1986. A conference sponsored by the IAEA, European Commission and WHO was held at the Austria Centre, Vienna over 8-12 April 1996, and brought together more than 800 scientists and government officials in the fields of radiation safety and nuclear energy. The conference reviewed the scientific, medical, environmental, social and political issues involved in assessing Chernobyls's impact. It is clear the effects of the accident have given rise to social and economic impacts which are of greater significance than radiation exposure. A question posed at the conclusion of the review of the last decade was : What policies and measures can now be developed by the most affected countries for the public and for the Chernobyl plant to take into account both the present radiological risk and the economic, social and psychological impacts of the accident and to yield the most benefit?

1997-01-01

Dynamics of the 137 Cs content in the components of the forests in the 30-km zone around the Chernobyl nuclear power plant (NPP) in 1986-1994 are associated mainly with such factors as the size of radioactive particles in the fallout, ecosystem humidification and soil type, tree age. The influence of particle size was especially noticeable between 1986-1987 and was displayed by low biological availability of radionuclides in the near part of the zone (within the 10-km radius circle around the NPP) in comparison with more distant regions (within the 30-km radius circle). Later, the expression of this influence decreased and transfer factor (the ratio of 137 Cs content in overground phytomass to the soil contamination density) became approximately the same for all plots with similar ecological and fallout characteristics. Humidity of landscape and soil type determined the velocity of radionuclide vertical migration in the soil and 137 Cs biological availability. These parameters were maximum for the hydromorphic soils of wet landscapes enriched in organic substance and poor clayey minerals. Differences of 137 Cs accumulation in overground phytomass of trees caused by tree age are displayed in the higher 137 Cs concentration in structural parts of young trees as compared with old ones

Chernobyl and Fukushima nuclear accidents: what has changed in the use of atmospheric dispersion modeling?

Science.gov (United States)

Benamrane, Y; Wybo, J-L; Armand, P

2013-12-01

The threat of a major accidental or deliberate event that would lead to hazardous materials emission in the atmosphere is a great cause of concern to societies. This is due to the potential large scale of casualties and damages that could result from the release of explosive, flammable or toxic gases from industrial plants or transport accidents, radioactive material from nuclear power plants (NPPs), and chemical, biological, radiological or nuclear (CBRN) terrorist attacks. In order to respond efficiently to such events, emergency services and authorities resort to appropriate planning and organizational patterns. This paper focuses on the use of atmospheric dispersion modeling (ADM) as a support tool for emergency planning and response, to assess the propagation of the hazardous cloud and thereby, take adequate counter measures. This paper intends to illustrate the noticeable evolution in the operational use of ADM tools over 25 y and especially in emergency situations. This study is based on data available in scientific publications and exemplified using the two most severe nuclear accidents: Chernobyl (1986) and Fukushima (2011). It appears that during the Chernobyl accident, ADM were used few days after the beginning of the accident mainly in a diagnosis approach trying to reconstruct what happened, whereas 25 y later, ADM was also used during the first days and weeks of the Fukushima accident to anticipate the potentially threatened areas. We argue that the recent developments in ADM tools play an increasing role in emergencies and crises management, by supporting stakeholders in anticipating, monitoring and assessing post-event damages. However, despite technological evolutions, its prognostic and diagnostic use in emergency situations still arise many issues. Copyright © 2013 Elsevier Ltd. All rights reserved.

Observations on the Chernobyl Disaster and LNT

Jaworowski, Zbigniew

2010-01-01

The Chernobyl accident was probably the worst possible catastrophe of a nuclear power station. It was the only such catastrophe since the advent of nuclear power 55 years ago. It resulted in a total meltdown of the reactor core, a vast emission of radionuclides, and early deaths of only 31 persons. Its enormous political, economic, social and psychological impact was mainly due to deeply rooted fear of radiation induced by the linear non-threshold hypothesis (LNT) assumption. It was a historic event that provided invaluable lessons for nuclear industry and risk philosophy. One of them is demonstration that counted per electricity units produced, early Chernobyl fatalities amounted to 0.86 death/GWe-year), and they were 47 times lower than from hydroelectric stations (∼40 deaths/GWe-year). The accident demonstrated that using the LNT assumption as a basis for protection measures and radiation dose limitations was counterproductive, and lead to sufferings and pauperization of millions of inhabitants of contaminated areas. The projections of thousands of late cancer deaths based on LNT, are in conflict with observations that in comparison with general population of Russia, a 15% to 30% deficit of solid cancer mortality was found among the Russian emergency workers, and a 5% deficit solid cancer incidence among the population of most contaminated areas.

The safety of nuclear power plants in Eastern Europe

International Nuclear Information System (INIS)

Hoehn, J.; Niehaus, F.

1997-01-01

Nuclear power plant operators and nuclear organizations from the West and from the East cooperate at many levels. The G7 and G24 nations have taken it upon themselves to improve the safety of Eastern nuclear power plants. The European Union has launched support programs, i.e. Technical Assistance to the Commonwealth of Independent States (Tacis) and Pologne-Hangrie: Aide a la Reconstruction Economique (Phare), and founded the European Bank for Reconstruction and Development. The countries of Central and Eastern Europe operate nuclear power plants equipped with VVER-type pressurized water reactors and those equipped with RBMK-type reactors. The safety of these two types of plants is judged very differently. Among the VVER plants, a distinction is made between the older and the more recent 440 MWe lines and the 1000 MWe line. Especially the RBMK plants (Chernobyl-type plants) differ greatly as a function of location and year of construction. Even though they do not meet Western safety standards and at best can be backfitted up to a certain level, it must yet be assumed that they will remain in operation to the end of their projected service lives for economic reasons.

Public acceptance has become an important factor in nuclear power program particularly after Chernobyl accident and recent rapid democratization in Korea. A method reflecting public opinions in order to improve public acceptance is to find out the public preference values for its policy alternatives. In this study, the conjoint analysis was applied to find out the quantitative values of public preferences for twelve policy alternatives to support communities surrounding nuclear power plants in Korea. To implement the analysis, questionnaires of trade-off matrix form were mailed to the science teachers of middle or high school through-out the country who had the experience of visiting nuclear power plant. The quantitative preference values for potential policy alternatives were estimated, which made it possible to forecast the effectiveness of each option. It was revealed that the improvement of reactor safety 100 times and the establishment of civilian monitoring system for nuclear safety would be two best options to improve public acceptance of nuclear power in Korea.

Between May 28 - June 4, 2005, under the organization of the Hungarian Nuclear Society (HNS) and the Hungarian Young Generation Network (HYGN) - which operates within the framework of the HNS - a scientific expedition visited the Chernobyl Nuclear Power Plant and the surrounding exclusion zone. The participants were young Hungarian nuclear professionals supervised by more experienced experts. The main scientific goals of the expedition were the followings: Get personal experiences in a direct way about the current status of the Chernobyl Power Plant and its surroundings, the contamination of the environment and about the doses. Gather information about the state of the shut down power plant and the shelter built above the damaged 4. unit. Training of young nuclear experts by performing on site measurements. The Hungarian expedition successfully achieved its objectives by performing wide-range of environmental and dosimetric measurements and collecting numerous biological and soil samples. Within the 30-km exclusion zone the influence of the accident occurred 20 years ago still could be measured clearly; however the level of the radioactivity is manageable in most places. The dosimetric measurements showed that no considerable exposure occurred among the members of the expedition. The analysis of samples has been started at the International Chernobyl Center in Slavutich. During the expedition not only environmental sampling and in-situ measurements were carried out but it was also well documented with photos and video recordings for educational, training and PR purposes. A documentary TV film was recorded during the expedition. The first-hand knowledge acquired during the expedition helps the authentic communication of the accident and its present-day consequences, which is especially important in 2006, 20 years after the Chernobyl accident. Since Ukraine and Hungary are neighbor countries the media constantly discuss the accident, the consequences and the risks of

Compensation for the damage caused by the Chernobyl disaster

The teachings of the accident at the nuclear power plant of Chernobyl clearly showed that the existing rules of Russian legislation cannot handle the problems in respect of civil liability for nuclear damage. This paper describes how the Soviet State and Soviet law tried to cope with the question of compensation for damage to human health and property in a special legal situation, due to the lack of any particular legislation covering this area and to the fact that the USSR is a Party neither to the Vienna nor the Paris Convention. In 1991 a law of the Russian Federation 'On the social protection of citizens who suffered as a consequence of the Chernobyl disaster' established a State system of services and compensation for such damage and the procedure for financing was laid down by a ministerial letter. 4 refs

The Chernobyl Nuclear Power Plant (CNPP) accident occurred on April 26 of 1986, it is still an episode of interest, due to the large amount of radionuclides dispersed in the atmosphere. Caesium-137 ((137)Cs) is one of the main radionuclides emitted during the Chernobyl accident, with a half-life of 30years, which can be accumulated in humans and animals, and for this reason the impacts on population are still monitored today. One of the main parameters in order to estimate the exposure of population to (137)Cs is the concentration in the air, during the days after the accident, and the deposition at surface. The transport and deposition of (137)Cs over Europe occurred after the CNPP accident has been simulated using the WRF-HYSPLIT modeling system. Four different vertical and temporal emission rate profiles have been simulated, as well as two different dry deposition velocities. The model simulations could reproduce fairly well the observations of (137)Cs concentrations and deposition, which were used to generate the 'Atlas of Caesium deposition on Europe after the Chernobyl accident' and published in 1998. An additional focus was given on (137)Cs deposition and air concentrations over Turkey, which was one of the main affected countries, but not included in the results of the Atlas. We estimated a total deposition of 2-3.5 PBq over Turkey, with 2 main regions affected, East Turkey and Central Black Sea coast until Central Anatolia, with values between 10 kBq m(-2) and 100 kBq m(-2). Mean radiological effective doses from simulated air concentrations and deposition has been estimated for Turkey reaching 0.15 mSv/year in the North Eastern part of Turkey, even if the contribution from ingestion of contaminated food and water is not considered, the estimated levels are largely below the 1 mSv limit indicated by the International Commission on Radiological Protection.

After having recalled the Chernobyl accident process and consequences for the power station buildings, and also the emergency interventions to cover the reactor and avoid that the molten core reaches underground waters, the author proposes a brief overview of the consequences at the international level in the field of nuclear safety with the emergence of a culture of safety which has been applied in other industrial sectors, with the improvement of the quality of transmitted information, and with the lessons learned about the efficiency of early ingestion of iodine pills. The author evokes the construction of a containment arch to dismantle the whole installation, comments the various results published on health consequences and gives some explanations about their discrepancy

Phasing out nuclear power, the swedish experience

International Nuclear Information System (INIS)

Fredriksson, Y.

2000-01-01

This article presents the chronological steps in the phasing-out of nuclear energy in Sweden. In 1980 a consultative referendum was held and it was decided that: i) no further expansion of nuclear capacity beyond the 12 reactors in operation or already under construction, ii) all nuclear power plants should be decommissioned by the year 2010. In 1988, as a consequence of the Chernobyl nuclear accident, the Swedish parliament decided that one reactor should be closed down in 1995 and a second in 1996. In 1991 the parliament proposed a new energy program for a 5 year period. The main measure was a huge financial support for increasing energy efficiency and for developing environmental sound technologies. At the same time the parliament repealed the 1991 decision of closing 1 reactor in 1995 and made the phase-out process dependent on the results of the new energy policy. In 1994 a parliamentary Commission was appointed to estimate the results of 1991 energy policy. The results were meager and disappointing so the Commission considered that a number of objectives (the climate issue, employment, welfare and competitiveness) remained unresolved if all nuclear power generation should be phased out by 2010. However, the Commission also considered it important to start the phasing-out process at an early stage and stated that one reactor could be closed down without noticeably affecting the power balance. The Barsebaeck reactor is to be closed before the end of november 1999. (A.C.)

In this line the Chernobyl nuclear accident (CNA) that look place on the 26th April 1986 at the Chernobyl Nuclear Power Station (CNPS) is an eloquent example. Radioactive substances produced in the result of CNA fell out in a significant part of the Europe, including the Republic of Moldova territory, affecting more than 5,000,000 persons. In CNA consequences liquidation participated a lot of military staff including a great number of reservists. Lack of previous experience in the field (it was the first large-scale nuclear accident) made it impossible to prepare specially trained personnel for CNA limitation and liquidation. Consequently a lot of military staff even from the first days presented to medical authorities with a gamma of symptoms, which were henceforth characterized as somatic diseases after detailed investigations. Ionizing radiation influence on the health status of the participants in diminishing of consequences of the Chernobyl nuclear accident (PDCCNA) evaluation is difficult enough and so calls for an ample multilateral study applying modern diagnostic techniques. Large studies were yet conducted in the Russian Federation, the Ukraine and the Republic of Belarus. Acquired data suggests the existence of noticeable deteriorating effect of ionizing radiation produced secondary to CNA with the increased incidence of health status disturbances in affected population. Approximately 3500 inhabitants from the Republic of Moldova took part in the Chernobyl nuclear accident consequences liquidation. Study objective comprises the determination of clinical, immunological and cytogenetic features in PDCCNA from the Republic of Moldova and their descendants.

The report describes how the elimination of nuclear power has affected power production, industry and education in Italy. A referendum after the Chernobyl accident led to the phase-out, after 20 years of operation. The most important consequence has been to loss of competence in an area where Italy has been advanced for several years. Industry, in particular, has lost most of its competence, and universities have lost most of the students in reactor technology. Dependence on foreign energy supply is highest among the industrialized countries. The future for nuclear power is also discussed, changes in the political climate can make room for a return of nuclear power. 22 refs, 4 figs.

The medical implications of nuclear power plant accidents

1989-11-01

This paper examines the UK position regarding the potential for an accident at a nuclear power plant, the safeguards in place to prevent such an accident occurring and the emergency procedures designed to cope with the consequences should one occur. It focuses on the role of the medical services and examines previous accidents to suggest the nature and likely scale of response that may need to be provided. It is apparent that designs of UK nuclear power stations are robust and that the likelihood of a significant accident occurring is extremely remote. Emergency arrangements are, however, in place to deal with the eventuality should it arise and these incorporate sufficient flexibility to accommodate a wide range of accidents. Analysis of previous nuclear accidents at Windscale, Three Mile Island and Chernobyl provide a limited but valuable insight into the diversity and potential scale of response that may be required. It is concluded that above all, the response must be flexible to enable medical services to deal with the wide range of effects that may arise. (author)

The devastation left behind from the Chernobyl nuclear power plant (ChNPP) Unit 4 accident which occurred on April 26, 1986 presented unparalleled technical challenges to the world engineering and scientific community. One of the largest tasks that are in progress is the design and construction of the New Safe Confinement (NSC). The NSC is an engineered enclosure for the entire object shelter (OS) that includes a suite of process equipment. The process equipment will be used for the dismantling of the destroyed Chernobyl Nuclear Power Plant (ChNPP) Unit. One of the major mechanical handling systems to be installed in the NSC is the Main Cranes System (MCS). The planned decontamination and decommissioning or dismantling (D and D) activities will require the handling of heavily shielded waste disposal casks containing nuclear fuel as well as lifting and transporting extremely large structural elements. These activities, to be performed within the NSC, will require large and sophisticated cranes. The article will focus on the unique design features of the MCS for the D and D activities. (authors)

Public attitudes towards the accident at Chernobyl in April 1986 are discussed. Although affected by the radioactive fallout from Chernobyl, people in West Germany were still prepared to vote, only 3 months later, for political parties who would not change the nuclear situation, not for the 'Greens' who would. The whole issue is seen as a question of values and alternatives. (UK)
