Australia - a nuclear weapons testing ground

International Nuclear Information System (INIS)

Dobbs, Michael.

1993-01-01

Between 1952 and 1958 Britain conducted five separate nuclear weapons trials in Australia. Australia had the uninhabited wide open spaces and the facilities which such tests need and Britain was able to use its special relationship with Australia to get agreement to conduct atomic tests in Australia and establish a permanent test site at Maralinga. Other non-nuclear tests were conducted between 1953-1963. The story of Britain's involvement in atomic weapons testing in Australia is told through its postal history. Both official and private covers are used to show how the postal communications were established and maintained throughout the test years. (UK)

Towards a nuclear-weapon-free zone in the Middle East

International Nuclear Information System (INIS)

1991-01-01

Every year since 1974 the General Assembly adopted a resolution on the subject ''Establishment of a nuclear-weapon-free zone in the Middle East''. By that resolution, the General Assembly requested the Secretary-General to undertake a study on effective and verifiable measures which would facilitate the establishment of a nuclear-weapon-free zone in the Middle East, taking into account the circumstances and characteristics of the Middle East, as well as the views and the suggestions of the parties of the region, and to submit this study to the General Assembly. The study was carried out between July 1989 and August 1990. The study discusses a number of steps and measures that could ease the process leading to the establishment of a nuclear-weapon-free zone in the Middle East. Those measures could be undertaken independently or in conjunction with each other, as well as by individual States or jointly by several, and also on a reciprocal basis; each of them would move the States concerned closer to their ultimate objective - the establishment of a zone free of nuclear weapons

Psychological markers underlying murder weapon profile: a quantitative study.

Kamaluddin, M R; Othman, A; Ismail, K H; Mat Saat, G A

2017-12-01

The horrific nature of murder using different types of weapons has been an important focal point of many criminological studies. Weapons that are used in murders seem to play dominant roles in murder investigations as they may provide information leading to arrest. The established factors for weapon usage include environmental context, demography and availability of weapons. However, there is insufficient research attention on the psychological functioning of murderers for particular weapon usage. In light of this, the current study seeks to narrow this gap of information by identifying the influences of psychological traits on weapon usage among a sample of male murderers. The present cross-sectional study was conducted among 71 male murderers incarcerated in 11 prisons within Peninsular Malaysia. The selection of the sample was based on predetermined selection criteria using a purposive sampling method. A guided self-administered questionnaire comprising sociodemography variables and four Malay validated psychometric instruments: Zuckerman-Kuhlman Personality Questionnaire-40-Cross-Culture, Self-control Scale, "How I Think" Questionnaire and Aggression Questionnaire; was used. Independent sample t-test was performed to establish the mean score differences of psychological traits between the murderers who used single and multiple weapons while Kruskal-Wallis tests were carried out to ascertain the differences between the specific types of weapons used among the murderers. Following this, one-way ANOVA was carried out to ascertain the psychological trait differences among the murderers according to the different sources of weapon. Results indicated specific psychological traits influenced the number(s), source(s) and type(s) of weapon used in committing murder. The findings have implications for the psychological profiling of unknown murderers within the Malaysian context.

The real value of nuclear-weapon-free zones

International Nuclear Information System (INIS)

Carasales, J.

1998-01-01

The international community has greeted the establishment of two new nuclear weapon-free zones with praise. Africa and South Asia are the regions which will join, once the respective treaties are ratified and in force, Latin America and the South Pacific to ensure that extensive areas of the earth remain free of nuclear weapons. The usual reaction to these accomplishments is to hail them as important contributions to international peace and security, and as meaningful steps towards a world free of nuclear weapons. The nuclear weapon-free zones have their value but this value relates mainly to the countries within the zone. The interest of nuclear-weapon states are not really affected, or, if they are, the influence is not significant. One should bear in mind that the really important and meaningful nuclear weapon-free zones have yet to be achieved

Effective and verifiable measures which would facilitate the establishment of a nuclear-weapon-free zone in the Middle East

International Nuclear Information System (INIS)

1991-01-01

The present study of the path to a nuclear-weapon-free zone for the Middle East has been made in a spirit of ''realistic optimism''. There clearly is no instant solution to the problem. In the end, the co-operation of the international community as a whole points to a central role for the United Nations. The present study lists a number of measures to build mutual confidence and prepare the way for the establishment of a nuclear-weapon-free zone. They are not arranged in order of priority or importance. Some of these measures can be implemented unilaterally by States of the region or outside it. Others may require agreement among groups of States. When it will become possible to arrange a negotiating conference involving all the core States in the region, together with some outside States at some point, a major breakthrough in confidence-building will have occurred. NPT parties with relatively advanced nuclear programmes, involving, for example, the construction of research or power reactors, can arrange those programmes to minimize suspicions that they might also serve a military objective. The programmes can avoid any use of weapon-grade fissionable material and they can invite inspection of any facilities that use significant quantities of nuclear material. Stocks of natural uranium, heavy water and tritium can be declared

This portion of the Glenn T. Seaborg journal concerns the 12-year period during which I served as Director of the Division of Nuclear Chemistry of the Radiation Laboratory (now the Lawrence Berkeley Laboratory). This portion of my journal consists of Volume 5 (January 1, 1951--December 31, 1951). The journal is based on my notebook entries; memos covering phone calls, appointments, and meetings; minutes of meetings; my appointment calendars and correspondence files; the Radiation Laboratory Chemistry Division personnel files and travel vouchers; laboratory notebooks of my scientific colleagues and cyclotron bombardment logs; some catalogs and materials from the Bancroft Library and the University Archives; back issues of the campus newspaper the Daily California and clippings from S.F. Bay Area newspapers found in my scrapbook, etc. Helen was able to provide me with some of her appointment calendars, which helped clarify family and social activities. Many of these resources provided clear and detailed material. Other notes made hastily and causally, using initials for people's names and rather cryptic abbreviations; however, when these were deciphered, they provided surprisingly complete information

A nuclear-weapon-free world and true disarmament

1999-01-01

This preliminary note about is important to consider when discussing hopes of achieving a nuclear-weapon-free world. Without a serious effort to establish intelligent, powerful bodies to control and judge the behavior of the nations on Earth, whatever they future weapons may be, the objective to reach a nuclear-weapon-free world may even succeed, but it is not enough to stop wars and death. Even more than that: if taken alone, as the 'Great Way', it could prove negative, for it could slow down the general effort to achieve peace on out planet. A nuclear-weapon-free world is of course a very good idea but two points must be discussed: how to achieve the nuclear-weapon-free world; and what will happen afterwards. Some considerations on the second point are made

The Review and Extension Conference of the Parties to the Non-Proliferation Treaty decided on the indefinite extension of the Treaty, and adopted two documents 'principles and Objectives for Nuclear Non-Proliferation and Disarmament' and 'Strengthening the Review Process for the Treaty'. In the former document, the Conference encourages the establishment of nuclear-weapon-free zones, on the conviction that such zones will enhance global and regional peace and security. Besides the Rarotonga Treaty, ASEAN countries plan to establish a nuclear-weapon-free zone in the South-East Asia

Structural adaptations to diverse fighting styles in sexually selected weapons.

Science.gov (United States)

McCullough, Erin L; Tobalske, Bret W; Emlen, Douglas J

2014-10-07

The shapes of sexually selected weapons differ widely among species, but the drivers of this diversity remain poorly understood. Existing explanations suggest weapon shapes reflect structural adaptations to different fighting styles, yet explicit tests of this hypothesis are lacking. We constructed finite element models of the horns of different rhinoceros beetle species to test whether functional specializations for increased performance under species-specific fighting styles could have contributed to the diversification of weapon form. We find that horns are both stronger and stiffer in response to species-typical fighting loads and that they perform more poorly under atypical fighting loads, which suggests weapons are structurally adapted to meet the functional demands of fighting. Our research establishes a critical link between weapon form and function, revealing one way male-male competition can drive the diversification of animal weapons.

The Swedish National Defence Research Establishment and the plans for Swedish nuclear weapons; Foersvarets forskningsanstalt och planerna paa svenska kaernvapen

Energy Technology Data Exchange (ETDEWEB)

Jonter, Thomas [Uppsala Univ. (Sweden). Dept. of History

2001-03-01

This study analyses the Swedish nuclear weapons research since 1945 carried out by the Swedish National Defence Research Establishment (FOA). The most important aspect of this research was dealing with protection in broad terms against nuclear weapons attacks. However, another aspect was also important from early on - to conduct research aiming at a possible production of nuclear weapons. FOA performed an extended research up to 1968, when the Swedish Government signed the Non-Proliferation Treaty (NPT), which meant the end of these production plans. Up to this date, five main investigations about the technical conditions were made, 1948, 1953, 1955, 1957 and 1965, which all together expanded the Swedish know-how to produce a bomb. The Swedish plans to procure nuclear weapons were not an issue in the debate until the mid 50's. The reason for this was simple, prior to 1954 the plans were secretly held within a small group of involved politicians, military and researchers. The change of this procedure did take place when the Swedish Supreme Commander in a public defence report in 1954 favoured a Swedish Nuclear weapons option. In 1958 FOA had reached a technical level that allowed the Parliament to make a decision. Two programs were proposed - the L-programme (the Loading Programme), to be used if the parliament would say yes to a production of nuclear weapons, and the S-programme (the Protection Programme), if the Parliament would say no. The debate on the issue had now created problems for the Social Democratic Government. The Prime Minister, Tage Erlander, who had earlier defended a procurement of nuclear weapons, was now forced to reach a compromise. The compromise was presented to the parliament in a creative manner that meant that only the S-programme would be allowed. The Government argued that the technical level did allow a 'freedom of action' up to at least the beginning of the 60's when Sweden was mature to make a decision on the issue

The 1951 Harvard student uprising against the intern match.

Science.gov (United States)

Nakayama, Don K; Hendren, W Hardy

2017-06-01

In the fall of 1951, a group of Harvard medical students led by W. Hardy Hendren, III organized a national movement against the newly instituted match that would assign graduating seniors to hospital internship programs. Before then, hospitals with intern positions to fill rushed to secure commitments from students, who in turn accepted the first decent offer that came their way. Knowing that students could not risk waiting for a better offer, hospitals pushed them into making early commitments. When some students began getting offers in their junior and sophomore years, medical schools, professional groups, and hospitals organized the National Inter-association Committee on Internships to deal with the issue. The intern match was thus organized and scheduled to take place in 1952. When the plan was announced in mid-October 1951, Hendren recognized that the proposed algorithm placed students at a disadvantage if they did not get their first choice of hospitals. Facing resistance at every step from the National Inter-association Committee on Internships and putting his standing at Harvard Medical School at risk, Hendren led a nationwide movement of medical students to change the procedure to one that favored students' choices. Their success <1 month later established in the inaugural match the fundamental ethic of today's National Resident Matching Program to favor students' preferences at every step of the process.

Space weapon technology and policy

Science.gov (United States)

Hitchens, Theresa

2017-11-01

The military use of space, including in support of nuclear weapons infrastructure, has greatly increased over the past 30 years. In the current era, rising geopolitical tensions between the United States and Russia and China have led to assumptions in all three major space powers that warfighting in space now is inevitable, and possible because of rapid technological advancements. New capabilities for disrupting and destroying satellites include radio-frequency jamming, the use of lasers, maneuverable space objects and more capable direct-ascent anti-satellite weapons. This situation, however, threatens international security and stability among nuclear powers. There is a continuing and necessary role for diplomacy, especially the establishment of normative rules of behavior, to reduce risks of misperceptions and crisis escalation, including up to the use of nuclear weapons. U.S. policy and strategy should seek a balance between traditional military approaches to protecting its space assets and diplomatic tools to create a more secure space environment.

Steps reducing reliance on deployed nuclear weapons en route to zero will be discussed. They include broadly enhancing cooperation and transparency agreements beyond the provisions for verifying limits on deployed strategic nuclear warheads and delivery systems in the New START treaty. Two questions that will be addressed are: What conditions would have to be established in order to maintain strategic stability among nations as nuclear weapons recede in importance? What would nuclear deterrence be like in a world without nuclear weapons?

The Atomic Weapons Research Establishment (AWRE) at Aldermaston discharges very small amounts of radioactive materials to the local environment. Calculations based on source information indicate that the resultant dose to the general public is less than 0.1% of the local natural radiation background. This conclusion is confirmed by the detailed and extensive environmental monitoring programme carried out by AWRE in the surrounding locality. (author)

We had a weapons science breakout session last week. Although it would have been better to hold it closer in time to this workshop, I think that it was very valuable. it may have been less of a 'short-sleeve' workshop environment than we would have liked, but as the first time two communities-the weapons community and the neutron scattering community- got together, it was a wonderful opportunity to transfer information during the 24 presentations that were made. This report contains discussions on the fundamental analysis of documentation of the enduring stockpile; LANSCE's contribution to weapons; spallation is critical to understanding; weapons safety assessments; applied nuclear physics requires cross section information; fission models need refinement; and establishing teams on collaborative projects

The weapons effect.

Science.gov (United States)

Benjamin, Arlin James; Bushman, Brad J

2018-02-01

In some societies, weapons are plentiful and highly visible. This review examines recent trends in research on the weapons effect, which is the finding that the mere presence of weapons can prime people to behave aggressively. The General Aggression Model provides a theoretical framework to explain why the weapons effect occurs. This model postulates that exposure to weapons increases aggressive thoughts and hostile appraisals, thus explaining why weapons facilitate aggressive behavior. Data from meta-analytic reviews are consistent with the General Aggression Model. These findings have important practical as well as theoretical implications. They suggest that the link between weapons and aggression is very strong in semantic memory, and that merely seeing a weapon can make people more aggressive. Copyright © 2017 Elsevier Ltd.

Flexible weapons architecture design

Science.gov (United States)

Pyant, William C., III

Present day air-delivered weapons are of a closed architecture, with little to no ability to tailor the weapon for the individual engagement. The closed architectures require weaponeers to make the target fit the weapon instead of fitting the individual weapons to a target. The concept of a flexible weapons aims to modularize weapons design using an open architecture shell into which different modules are inserted to achieve the desired target fractional damage while reducing cost and civilian casualties. This thesis shows that the architecture design factors of damage mechanism, fusing, weapons weight, guidance, and propulsion are significant in enhancing weapon performance objectives, and would benefit from modularization. Additionally, this thesis constructs an algorithm that can be used to design a weapon set for a particular target class based on these modular components.

Nuclear weapons modernizations

This article reviews the nuclear weapons modernization programs underway in the world's nine nuclear weapons states. It concludes that despite significant reductions in overall weapons inventories since the end of the Cold War, the pace of reductions is slowing - four of the nuclear weapons states are even increasing their arsenals, and all the nuclear weapons states are busy modernizing their remaining arsenals in what appears to be a dynamic and counterproductive nuclear competition. The author questions whether perpetual modernization combined with no specific plan for the elimination of nuclear weapons is consistent with the nuclear Non-Proliferation Treaty and concludes that new limits on nuclear modernizations are needed.

Both have engaged in discussions and have programs in various stages of development to dispose of excess plutonium and HEU. These fissile material disposition programs will take decades to complete. In the interim there will be, as there is now, hundreds of tons of separated weapon-usable fissile material stored in tens of thousands of transportable canisters, each containing from a few to several tons of kgs of weapon-usable fissile material. This material must be secured against theft and unauthorized use. To have high confidence that the material is secure, one must establish criteria against which the adequacy of the protective systems can be judged. For example, one finds such criteria in US Nuclear Regulatory Commission (USNRC) regulations for the protection of special nuclear materials

Re-examining the 1996 ICJ Advisory Opinion: Concerning the Legality of Nuclear Weapons

Directory of Open Access Journals (Sweden)

Jasjit Singh

2012-10-01

Full Text Available The primary objections raised against total elimination of nuclear weapons are built around a few arguments mostly of non-technical nature.Nuclear weapons and the strategies for their use have resulted in the establishment of a vicious circle within which the international community is trapped.The argument that the world will be unsafe without nuclear weapons is only meant to further the narrow self-interest of the nuclear weapon states and their allies.The World Court’s far-reaching 1996 advisory opinion concluded that almost any use or threat of use of nuclear weapons would violate international humanitarian law and law applicable in armed conflict, undermining most claims of nuclear weapon states regarding the legitimacy of possession, use or threat of use of nuclear weapons. The next logical step would be an initiative for a nuclear convention banning the use and threat of use of nuclear weapons in Asia and the adjoining oceans. But as long as the dominant elites in society and the nation-state believe in the utility of nuclear weapons for national security or as the currency of power, abolition of nuclear weapons will remain a mirage.

Prelude and first decade, 1951-1961

Shepherd, L. R.

The initiative leading to the establishment of the International Astronautical Federation (IAF) was taken in 1949 by the Stuttgart based Gesellschaft für Weltraumforschung (GfW), who proposed to other astronautical societies that a conference should be arranged to establish mutual co-operation. The British Interplanetary Society (BIS) agreed to organize such a conference in London in 1951, but in the interim the Groupement Astronautique Français (GAF) arranged a preliminary meeting to set up the agenda for the London meeting and to define its objectives. Representatives from astronautical groups in seven European countries and one South American society met in Paris in October 1950. Their meetings were preceded, on 30 September, by a large public gathering organized by the GAF, in the Sorbonne and was designated the Premier Congrès International d'Astronautique, a style which was to be adopted, in its English translation, for the subsequent annual conferences of the IAF. The representatives agreed that the objective of the London conference should be to create a federation of autonomous national astronautical societies, whose main purpose would be to provide an annual forum where these societies would meet. The London conference in September 1951, held in the City of Westminster, following the Paris precedent, was designated the IInd International Astronautical Congress. Astronautical and rocket societies from the ten countries were represented and became signatories to the agreement founding the IAF on 4 September 1951. The London congress set the pattern for subsequent congresses, in particular introducing technical lecture sessions. At the IIIrd Congress, held in Stuttgart, the first under the aegis of the newly founded IAF, a constitution was agreed and a Finance Committee was elected. The Constitution established that the Federation should be registered in Switzerland and be governed by a council of voting members—one only from each country. Subsequent

Combating the terrorist use of mass destruction weapons, particularly nuclear weapons

International Nuclear Information System (INIS)

Barakat, M.

2008-01-01

The risks of mass destruction weapons vary and also forms of damages resulting therefrom. While the effects of nuclear weapons are focused, sudden and comprehensive, the chemical weapons have limited impacts relatively unless used intensively severe prejudice to the element of surprise, and thus impaired the efficacy of their influences,especially that they affect exceptionally the individuals in the area of injury and biological weapons do not announce themselves except through their effect that appears later than the time of use as they affect exceptionally the organisms in the area of injury.The mass destruction weapons have turned from being a purely military means in the early twentieth century and have now become the means of violence against governments and countries that they should prepare themselves for and respond in ways of successful and effective countermeasures. Despite the fact that the acquisition of mass destruction weapons can be considered as a priority objective, which terrorist groups and organizations steadily seek but their accessibility is flanked by a lot of difficulties. Addressing the risk of further spread of nuclear weapons, and especially after doubling the power of those high-risk weapons, the international community has an approach to take a number of arrangements that complement each other to control and resist nuclear proliferation, either for the states or for terrorist groups.

This book discusses the acquisition of nuclear weapons by India and Pakistan and its effect on security of the South Asian region. The author uses quantitative analysis to establish the relationship between nuclearization and conventional stability in the region between 1971 and 2002. He shows a positive correlation between nuclear proliferation and conventional instability during these three decades. Thus, this study affirms that nuclear weapons have failed to prevent conflict in South Asia. In fact, they have escalated tensions

Environmental Restoration Strategic Plan. Remediating the nuclear weapons complex

International Nuclear Information System (INIS)

1995-08-01

With the end of the cold war, the US has a reduced need for nuclear weapons production. In response, the Department of Energy has redirected resources from weapons production to weapons dismantlement and environmental remediation. To this end, in November 1989, the US Department of Energy (DOE) established the Office of Environmental Restoration and Waste Management (renamed the Office of Environmental Management in 1994). It was created to bring under a central authority the management of radioactive and hazardous wastes at DOE sites and inactive or shut down facilities. The Environmental Restoration Program, a major component of DOE's Environmental Management Program, is responsible for the remediation and management of contaminated environmental media (e.g., soil, groundwater, sediments) and the decommissioning of facilities and structures at 130 sites in over 30 states and territories

Arms Control: US and International efforts to ban biological weapons

Energy Technology Data Exchange (ETDEWEB)

1992-12-01

The Bacteriological (Biological) and Toxin Weapons Convention, the treaty that bans the development, production, and stockpiling and acquisition of biological weapons was opened for signature in 1972 and came into force in 1975 after being ratified by 22 governments, including the depository nations of the USA, the United Kingdom, and the former Soviet Union. In support of the Convention, the USA later established export controls on items used to make biological weapons. Further, in accordance with the 1990 President`s Enhanced Proliferation Control Initiative, actions were taken to redefine and expand US export controls, as well as to encourage multilateral controls through the Australia Group. Thus far, the Convention has not been effective in stopping the development of biological weapons. The principal findings as to the reasons of the failures of the Convention are found to be: the Convention lacks universality, compliance measures are effective, advantage of verification may outweigh disadvantages. Recommendations for mitigating these failures are outlined in this report.

Statement to Second Conference of States Parties to African Nuclear-Weapon-Free Zone Treaty, 12 November 2012, Addis Ababa, Ethiopia

Amano, Y.

2012-01-01

It is a great pleasure for me to address this Second Conference of States Parties to the Treaty of Pelindaba. I compliment the countries of Africa for their tenacity in pursuing the goal of establishing a nuclear-weapon-free zone for decades, until the Treaty finally entered into force in 2009. Nuclear-weapon-free zones are a highly effective means of non-proliferation, arms control and disarmament. The five nuclear-weapon-free zones in existence today cover a total of 113 countries. Each has its own special characteristics, but they also have many important elements in common. All nuclear-weapon-free zones prohibit the development, stationing or testing of nuclear weapons in their respective regions. They all cover large inhabited areas. They provide for IAEA verification of the non-diversion of nuclear material. Nuclear-weapon-free zones have brought real security benefits, both regionally and to the whole world. The Treaty of Pelindaba incorporates a number of special features, including some measures which go beyond undertakings assumed by States Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) . For example, it makes provision for the dismantling and destruction of nuclear explosive devices manufactured by a Party to the Treaty before the Treaty entered into force. It prohibits attacks on nuclear installations in the nuclear-weapon-free zone. It bars the dumping of radioactive waste within the zone. In addition, the Treaty of Pelindaba contains a commitment to promote the use of nuclear science and technology for economic and social development. Parties are encouraged to make use of the assistance of the IAEA. They also pledge to maintain the highest standards of security and physical protection of nuclear material, facilities and equipment. In the Preamble to the Treaty, the Parties recognise that the establishment of other nuclear-weapon-free zones, especially in the Middle East, would enhance their security. Last November, I hosted an

The concept of nuclear-weapon-free zone, as it has developed from political deliberation since mid-1950s, today covers a spectrum of arrangements, geographically ranging from whole continent like Latin America to a corridor in central Europe, and functionally serving the purposes of preventing the spread of nuclear weapons and avoiding nuclear war. Among the nuclear-weapon-free zones proposed but not established, one is now being negotiated and two are subject to investigations published in official reports. These are the proposed zones in ASEAN area, The Middle East and Nordic Europe

Chemical Weapons are kind of Weapons of Mass Destruction (WMD). They were used large quantities in WWI. Historically, large quantities usage like WWI was not recorded, but small usage has appeared now and then. Chemical weapons are so called "Nuclear weapon for poor countrys" because it's very easy to produce/possession being possible. They are categorized (1) Nerve Agents, (2) Blister Agents, (3) Cyanide (blood) Agents, (4) Pulmonary Agents, (5) Incapacitating Agents (6) Tear Agents from the viewpoint of human body interaction. In 1997 the Chemical Weapons Convention has taken effect. It prohibits chemical weapons development/production, and Organization for the Prohibition of Chemical Weapons (OPCW) verification regime contributes to the chemical weapons disposal. But possibility of possession/use of weapons of mass destruction by terrorist group represented in one by Matsumoto and Tokyo Subway Sarin Attack, So new chemical terrorism countermeasures are necessary.

Perceived popularity of adolescents who use weapons in violence and adolescents who only carry weapons.

Science.gov (United States)

Wallace, Lacey N

2017-01-01

Prior research has found that persistently delinquent youth or more violent youth were less popular than their less delinquent peers (Young, 2013). However, recent research has also found that weapon carrying is associated with being more popular in adolescence (Dijkstra et al., 2010). The present paper examines the perceived popularity of adolescents who carry weapons in comparison to those who both carry and use weapons in acts of violence or threatened violence. Data consist of two waves from the National Longitudinal Study of Adolescent to Adult Health. Analyses use OLS regression with lagged predictors. This paper found no differences in number of friends between weapon carriers and weapon users. However, among both male and female gang members, those who did not use or carry weapons (abstainers) named significantly fewer friends than weapon users. Among females, weapon abstainers both named and were named by significantly more people than weapon users. These differences were not observed for males. Implications of these results and directions for future research are discussed.

Virtual nuclear weapons

Energy Technology Data Exchange (ETDEWEB)

Pilat, J.F.

1997-08-01

The term virtual nuclear weapons proliferation and arsenals, as opposed to actual weapons and arsenals, has entered in recent years the American lexicon of nuclear strategy, arms control, and nonproliferation. While the term seems to have an intuitive appeal, largely due to its cyberspace imagery, its current use is still vague and loose. The author believes, however, that if the term is clearly delineated, it might offer a promising approach to conceptualizing certain current problems of proliferation. The first use is in a reference to an old problem that has resurfaced recently: the problem of growing availability of weapon-usable nuclear materials in civilian nuclear programs along with materials made `excess` to defense needs by current arms reduction and dismantlement. It is argued that the availability of these vast materials, either by declared nuclear-weapon states or by technologically advanced nonweapon states, makes it possible for those states to rapidly assemble and deploy nuclear weapons. The second use has quite a different set of connotations. It is derived conceptually from the imagery of computer-generated reality. In this use, one thinks of virtual proliferation and arsenals not in terms of the physical hardware required to make the bomb but rather in terms of the knowledge/experience required to design, assemble, and deploy the arsenal. Virtual weapons are a physics reality and cannot be ignored in a world where knowledge, experience, materials, and other requirements to make nuclear weapons are widespread, and where dramatic army reductions and, in some cases, disarmament are realities. These concepts are useful in defining a continuum of virtual capabilities, ranging from those at the low end that derive from general technology diffusion and the existence of nuclear energy programs to those at the high end that involve conscious decisions to develop or maintain militarily significant nuclear-weapon capabilities.

Should Indonesia Accede to The 1951 Refugee Convention and Its 1967 Protocol?

2015-12-01

Full Text Available Being a non-party to the 1951 Convention relating to the Status of Refugees (“1951 Refugee Convention” and 1967 Protocol relating to the Status of Refugees (“1967 Protocol”, Indonesia does not have legal obligations to provide permanent resettlement for asylum seeker and/or refugee. However, as a transit country for those seeking shelter in Australia, Indonesia undergoes a myriad of issues resulting from illegal entrance by asylum seeker and/or refugee. Besides having neither legal framework nor domestic mechanism to handle asylum seekers and/or refugee, Indonesia’s immigration law identifies every foreigner including asylum seeker and refugee who unlawfully enter Indonesia’s territory into the same box as illegal migrant. It then leads to the arrest of asylum seeker and/or refugee to be put in an over-capacity detention center or other places. This paper will analyze various issues related to asylum seeker and refugee in Indonesia and to weigh whether it is indispensable for Indonesia to accede to the 1951 Refugee Convention and its 1967 Protocol.

The prevention of geographical proliferation of nuclear weapons: Nuclear-weapon-free zones and zones of peace in the Southern hemisphere

International Nuclear Information System (INIS)

Fujita, E.

1989-01-01

It is understandable that many Non-Nuclear Weapons States (NNWS) worry about the dangers of further geographical or spatial proliferation of nuclear weapons, as well as the extension to their regions of rivalries that are foreign to them. In this regard, there has been since the 1950's a number of proposals and initiatives to turn specific regions into nuclear-weapons-free zones and zones of peace in order to prevent or reduce the above mentioned threats. Although differences exits between the concepts of nuclear-weapon-free-zones and zones of peace as well as among the various NWFZ and ZP, inter se, they do share a common feature insofar as they represent a regional approach to the question of curbing the arms race, especially the nuclear one. This study will address some of these initiatives, examine their specific characteristics and assess their role in the prevention of the geographical proliferation of nuclear weapons. Among the relevant existing initiatives, those situated in the Southern Hemisphere offer an interesting focus of attention, in view of the fact that, together, they form a sort of a contiguous geographical area encompassing virtually half of the globe. The regions covered are the Antarctic, Latin American, South Pacific, South Atlantic and Indian Oceans. The first three have been established as nuclear-weapons-free-zones and the last two are in the process of being turned into zones of peace. The aim of this study is to compare similarities and differences among them and to identify the factors that condition their efficiency. By understanding their usefulness and their weaknesses, one many eventually construct useful paradigms for further regional initiatives to curb the arms race, specially the nuclear one

Identification of nuclear weapons

Science.gov (United States)

Mihalczo, J.T.; King, W.T.

1987-04-10

A method and apparatus for non-invasively indentifying different types of nuclear weapons is disclosed. A neutron generator is placed against the weapon to generate a stream of neutrons causing fissioning within the weapon. A first detects the generation of the neutrons and produces a signal indicative thereof. A second particle detector located on the opposite side of the weapon detects the fission particles and produces signals indicative thereof. The signals are converted into a detected pattern and a computer compares the detected pattern with known patterns of weapons and indicates which known weapon has a substantially similar pattern. Either a time distribution pattern or noise analysis pattern, or both, is used. Gamma-neutron discrimination and a third particle detector for fission particles adjacent the second particle detector are preferably used. The neutrons are generated by either a decay neutron source or a pulled neutron particle accelerator.

Security with nuclear weapons

International Nuclear Information System (INIS)

Karp, R.C.

1991-01-01

Recent improvements in East-West relations and the process of dramatic political change in Europe may result in unprecedented opportunities to reduce the global arsenal of nuclear weapons. Despite these welcome developments, the prospects for effectively controlling the spread of nuclear capability in the Third World have remained much less encouraging. The possibility of large reductions in nuclear weapons poses fundamental questions about their purpose. Why have some states chosen to acquire nuclear weapons? How and why have these decisions been maintained over time? Why have some states elected to approach, but not cross, the nuclear threshold? This book examines the commonalities and differences in political approaches to nuclear weapons both within and between three groups of states: nuclear, non-nuclear and threshold. The chapters explore the evolution of thinking about nuclear weapons and the role these weapons play in national security planning, and question the official security rationales offered by the nuclear weapon states for the maintenance of nuclear capabilities. For the non-nuclear weapon states, the book presents an analysis of alternative ways of assuring security and foreign policy effectiveness. For the threshold states, it examines the regional contexts within which these states maintain their threshold status. This book transcends traditional East-West approaches to analysis of nuclear issues by giving equal prominence to the issues of nuclear proliferation and non-nuclearism. The book also provides a comprehensive analysis of how current approaches to nuclear weapons have evolved both within and among the groups of countries under study

Warhead politics: Livermore and the competitive system of nuclear weapon design

Energy Technology Data Exchange (ETDEWEB)

Francis, Sybil [Massachusetts Inst. of Technology (MIT), Cambridge, MA (United States)

1995-06-01

From the 1950s onward, US evolved a two-laboratory system to design, develop, and test nuclear weapons. LANL (New Mexico) dates from World War II. The founding in 1952 of LLNL in California effectively established the two-laboratory system. Despite essentially identical missions, LANL and LLNL adopted different strategies and approaches to the development of nuclear weapons. This thesis looks to their joint history for an explanation of this and consequent questions (how did the two-laboratory system originate and evolve? how did it function? what impact did it have on nuclear weapons development?) The incentives and constraints that shaped laboratory strategies and outputs was determined by military demand for nuclear weapons, an informal mandate against laboratory duplication, congressional support for competition, and Livermore`s role as the ``second lab.`` This thesis discusses the laboratories` role in the arms race, organizational strategies for coping with changing political environments, dynamics of technological innovation, and the leverage of policymakers over large organizations.

1984-01-01

The authors take issue with the assessment that the advent of antisatellite weapons implies that the beneficial role of satellites in arms control, confidence building, and conflict resolution has been judged less important than their ability to support actual military operations. They argue that there is still an opportunity to negotiate a militarily significant and verifiable constraint on the growth of antisatellite technology that would be in the security interest of the US and the world as a whole. They base their opinion on an assessment of the roles of the existing military satellites and their vulnerability to antisatellite weapons and the probable impact of antisatellite weapons on various kinds of crisis and conflict. 10 figures, 1 table

2012-03-01

Starting with the definition of the word taboo as stated in a dictionary (a topic it would be unbecoming to evoke, under social and moral proprieties), the author of the first article discusses the status of the nuclear weapon, outlining that it is expensive, useless and monstrous. She notices that conventions on chemical weapons seem to be more efficient than the NPT, that, even if the reasons for abolition are known as well as ways to reach it, it seems difficult to actually address this issue. She evokes different voices coming from different countries or international bodies calling for this abolition. She also states that the nuclear weapon is not a deterrent weapon but a weapon of domination, and calls for the mobilisation of the civil society throughout the world. A second article states that the nuclear weapon is useless and expensive, and that we have to get rid of this hazard for the sake of the planet. Former ministers, Prime ministers, and generals consider that we can and must give up nuclear weapons, notably because the strategic context has completely changed since the fall of the Berlin wall, and support the action of Global Zero

Civil nuclear energy and the proliferation of nuclear weapons

International Nuclear Information System (INIS)

1990-04-01

The issue of whether civil nuclear programmes contribute to the risk of proliferation of nuclear weapons has been discussed since civil programmes were first considered, and has always complicated public attitudes to civil nuclear energy. This paper seeks to define the extent to which there is such ''linkage''. It does not deal with the linkages that exist between nuclear weapons and other industries and activities - for example, those involved in weapons delivery systems -since these are not within the Uranium Institute's area of competence. Linkage concerns regarding civil nuclear programmes arise primarily over the possibility of their being used to produce highly enriched uranium or plutonium for use in weapons. The technologies which can give rise directly to these materials are therefore ''sensitive'' in proliferation terms. Linkage may also arise through the relevant experience of the trained workforce. Such linkage is, however, limited by institutional, technical and economic factors. First, important institutional constraints on using a civil programme for military purposes exist in the form of a network of bilateral agreements and international treaties - most particularly the Nuclear Non-Proliferation Treaty - and the international safeguards inspections. Secondly, without access to the technologies of enrichment or reprocessing, the fissile material needed for an explosive cannot be obtained from any plant or process used to produce electricity. Finally, establishing a civil programme - with equipment whose design is optimized for electricity production - in order to develop weapons is an expensive route compared to specialized facilities.

The control of the proliferation of chemical weapons is no longer just on East-West issue; it is also an issue of concern in Third World Countries, and in some of the wealthier middle eastern nations, such as Kuwait

The US nuclear weapon infrastructure and a stable global nuclear weapon regime

Energy Technology Data Exchange (ETDEWEB)

Immele, John D [Los Alamos National Laboratory; Wagner, Richard L [Los Alamos National Laboratory

US nuclear weapons capabilities -- extant force structure and nuclear weapons infrastructure as well as declared policy -- influence other nations' nuclear weapons postures, at least to some extent. This influence can be desirable or undesirable, and is, of course, a mixture of both. How strong the influence is, and its nature, are complicated, controversial, and -- in our view -- not well understood but often overstated. Divergent views about this influence and how it might shape the future global nuclear weapons regime seem to us to be the most serious impediment to reaching a national consensus on US weapons policy, force structure and supporting infrastructure. We believe that a paradigm shift to capability-based deterrence and dissuasion is not only consistent with the realities of the world and how it has changed, but also a desirable way for nuclear weapon postures and infrastructures to evolve. The US and other nuclear states could not get to zero nor even reduce nuclear arms and the nuclear profile much further without learning to manage latent capability. This paper has defined three principles for designing NW infrastructure both at the 'next plateau' and 'near zero.' The US can be a leader in reducing weapons and infrastructure and in creating an international regime in which capability gradually substitutes for weapons in being and is transparent. The current 'strategy' of not having policy or a Congressionally-approved plan for transforming the weapons complex is not leadership. If we can conform the US infrastructure to the next plateau and architect it in such a way that it is aligned with further arms reductions, it will have these benefits: The extant stockpile can be reduced in size, while the smaller stockpile still deters attack on the US and Allies. The capabilities of the infrastructure will dissuade emergence of new challenges/threats; if they emerge, nevertheless, the US will be able to deal with them in

Nuclear weapons complex

Rezendes, V.S.

1992-04-01

In addition to long-standing safety and environmental problems plaguing the nuclear weapons complex, this paper reports that the Department of Energy (DOE) faces a major new challenge-how to reconfigure the weapons complex to meet the nation's defense needs in the 21st century. Key decisions still need to be made about the size of the complex; where, if necessary, to relocate various operations; what technologies to use for new tritium production; and what to do with excess weapons-grade material. The choices confronting DOE and Congress are difficult given the conflicting demands for limited resources

Building on recent work in uncertainty quanti cation, we examine the use of imprecise probability methods to better characterize expert knowledge and to improve on misleading aspects of Bayesian analysis with informative prior distributions. Quantitative approaches to incorporate uncertainties in weapons certi cation are subject to rigorous external peer review, and in this regard, certain imprecise probability methods are well established in the literature and attractive. These methods are illustrated using experimental data from LANL detonator impact testing.

The process described in the paper is being applied as part of the design verification of a replacement component designed for a nuclear weapon currently in the active stockpile. This process is an adaptation of the process successfully used in nuclear weapon development programs. The verification process concentrates on evaluating system response to radiation environments, verifying system performance during and after exposure to radiation environments, and assessing system survivability.

Nuclear Weapons Enterprise Transformation - A Sustainable Approach

International Nuclear Information System (INIS)

O'Brien, K H

2005-01-01

Nuclear weapons play an essential role in United States (U.S.) National Security Policy and a succession of official reviews has concluded that nuclear weapons will continue to have a role for the foreseeable future. Under the evolving U.S. government policy, it is clear that role will be quite different from what it was during the Cold War. The nuclear-weapons stockpile as well as the nuclear-weapons enterprise needs to continue to change to reflect this evolving role. Stockpile reductions in the early 1990s and the Stockpile Stewardship Program (SSP), established after the cessation of nuclear testing in 1992, began this process of change. Further evolution is needed to address changing security environments, to enable further reductions in the number of stockpiled weapons, and to create a nuclear enterprise that is cost effective and sustainable for the long term. The SSP has successfully maintained the U.S. nuclear stockpile for more than a decade, since the end of nuclear testing. Current plans foresee maintaining warheads produced in the 1980s until about 2040. These warheads continue to age and they are expensive to refurbish. The current Life Extension Program plans for these legacy warheads are straining both the nuclear-weapons production and certification infrastructure making it difficult to respond rapidly to problems or changes in requirements. Furthermore, refurbishing and preserving Cold-War-era nuclear weapons requires refurbishing and preserving an infrastructure geared to support old technology. Stockpile Stewardship could continue this refurbishment approach, but an alternative approach could be considered that is more focused on sustainable technologies, and developing a more responsive nuclear weapons infrastructure. Guided by what we have learned from SSP during the last decade, the stewardship program can be evolved to address this increasing challenge using its computational and experimental tools and capabilities. This approach must start

An Unusual Partnership: Brazilian-Italian Forms of Cooperation in the Nuclear Field (1951-1986)

International Nuclear Information System (INIS)

Patti, Carlo

2017-01-01

This chapter discusses the Brazilian-Italian cooperation in the nuclear field between the early 1950s and 1986. Since the late 1930s, Italian or Italian-Brazilian scientists promoted the development of studies in nuclear physics. Immediately after World War II, the Brazilian-Italian collaboration continued. Between the 1950s and the 1970s, Brazilian nuclear scientists studied in Italian institutions. Relying on primary sources from Brazilian archives and oral history interviews with protagonists of the Brazilian nuclear program, this chapter explore the relations between Italy and Brazil from 1951, the year of the establishment of the Brazilian nuclear program, until the 1980s. This study focuses on the bidirectional transfer of knowledge on sensitive technologies, and on the formal and informal cooperation between the two countries.

The morality of weapons research.

Science.gov (United States)

Forge, John

2004-07-01

I ask whether weapons research is ever justified. Weapons research is identified as the business of the engineer. It is argued that the engineer has responsibility for the uses to which the tools that he designs can be put, and that responsibility extends to the use of weapons. It is maintained that there are no inherently defensive weapons, and hence there is no such thing as 'defensive' weapons research. The issue then is what responsibilities as a professional the engineer has in regard to such research. An account is given to ground the injunction not to provide the means to harm as a duty for the engineers. This account is not, however, absolutist, and as such it allows justifiable exceptions. The answer to my question is thus not that weapons research is never justified but there must be a strong assurance that the results will only be used as a just means in a just cause.

Making weapons, talking peace

International Nuclear Information System (INIS)

York, H.F.

1987-01-01

The memoirs of the author traces his life from his first-year graduate studies in physics at the University of Rochester in 1942 to his present position as Director of the University of California's Institute on Global Conflict and Cooperation. The part of his life involved in making weapons extends from 1942 to 1961. During this period, he worked with E.O. Lawrence on the Manhattan Project and served as director of Livermore after it became the Atomic Energy Commission's second nuclear weapons laboratory. He also served on many government advisory boards and commissions dealing with nuclear and other weapons. In 1961, the combination of a heart attack and changes in administration in Washington led York too return to the University of California for the talking peace portion of his life. He has since become a public exponent of arms control and disarmament and the futility of seeking increased security through more and better nuclear weapons. York's explanation of his move from making weapons to talking peace leaves the reader with a puzzle

Do Weapons Facilitate Adolescent Delinquency? An Examination of Weapon Carrying and Delinquency Among Adolescents.

This article examines whether weapon carrying influences the frequency and variety of violent, property, and drug delinquency adolescents commit through fixed-effects analyses of data from the Rochester Youth Development Study (RYDS). We conclude that weapon carrying contributes to violent, substance, and property delinquency, and delinquent behaviors learned during weapon carrying continue to affect substance and property delinquency long after carrying has ceased.

Prerequisites for a nuclear weapons convention

International Nuclear Information System (INIS)

Liebert, W.

1999-01-01

A Nuclear Weapons Convention (NWC) would prohibit the research, development, production, testing, stockpiling, transfer, use and threat of use of nuclear weapons and would serve their total elimination.' In this fashion it follows the model laid out by the biological and chemical weapons conventions. The NWC would encompass a few other treaties and while replacing them should learn from their experiences. The Nuclear Weapons Convention should at some given point in the future replace the Non-Proliferation Treaty (NPT) and so resolve its contradictions and shortcomings. The main objectives of an NWC Would be: reduction of the nuclear arsenals of the 'five' nuclear weapons powers down to zero within a set of fixed periods of time; elimination of stockpiles of weapons-usable materials and, where existent, nuclear warheads in de-facto nuclear weapon and threshold states; providing assurance that all states will retain their non-nuclear status forever

Weapons and hope

International Nuclear Information System (INIS)

Dyson, F.

1984-01-01

The British-born physicist presents a full-blown critique of US weapons policy. His careful evaluation of opposing views leads him to endorse a live-and-let-live concept of arms control, which would reject both assured destruction and first use of nuclear weapons in favor of abolishing them. Dyson's faith in the humane progress of military technology and his tolerance of dangerous conventional weapons will not please dovish readers, while his denunciation of military idolatry and his support of a nuclear freeze will disappoint some hawks. Along with moving personal memories of war and pacifism, the most original sections of the book are the author's insightful comments about the Soviet Union and the issue of verification

Maintaining non-nuclear weapon status

International Nuclear Information System (INIS)

Muller, H.

1991-01-01

Among the some 170 sovereign states in the world, five are legally recognized as nuclear weapon states (NWS) under the terms of the 1968 Non-Proliferation Treaty (NPT). Six countries (Argentina, Brazil, India, Israel, Pakistan, and South Africa) are counted as threshold states: they possess sizeable unsafeguarded nuclear facilities or have passed the brink of a nuclear test or of clandestine weapon production. Six other countries (Iran, Iraq, Libya, Taiwan, and North and South Korea) have been suspected periodically of either considering the nuclear weapon option or of working secretly on the development of weapons. Thus, about 150 non-nuclear weapon states (NNWS) remain which neither possess nuclear weapons nor strive to acquire them. These states are distributed throughout the globe and encompass highly industrialized as well as underdeveloped countries, liberal democracies, socialist states, sheikdoms and dictatorships. Some NNWS face acute military threats; other are far removed from the quarrels of the world, as in the case of some remote fortunate islands. Furthermore, NNWS may be members of nuclear-umbrella alliances or may have opted for a policy of neutrality or non-alignment

The return of nuclear weapons

International Nuclear Information System (INIS)

Calvez, Jean-Yves

2005-01-01

Written after the 2005 NPT review conference, this article first recalls the early stages of nuclear proliferation: acquisition of nuclear weapons by Great-Britain, USSR, France and China, and creation of the NPT in 1970. The author briefly evokes some weaknesses and violations of this treaty: emergence of new nuclear powers (India, Pakistan, Israel) and of nuclear weapon programmes (Iran, North Korea). He outlines the lack of true rules to impede countries to develop nuclear weapons, and then states that the only solution seems to be a simple abolition of these weapons. This option is notably supported by the Catholic Church as outlined and recalled here. The author discusses the situation of this abolition option, and notices that, even though NPT members committed themselves on this way, some also decided to develop new and smaller weapons. Then, it becomes always more difficult to persuade countries not to possess these weapons. The author finally discusses the issues of terrorism threat in relationship to the miniaturisation process, and regrets the lack of commitment in an abolition process

Eichel, T; Dreux, M L

2017-03-01

During the poliomyelitis epidemics of the last century hospitals were inundated with patients in acute respiratory failure. Between 1946 and 1949, Nandor (Ferdinand) Eichel documented the use of the iron lung in children with acute poliomyelitis at the University Children's Hospital, Zurich. The aim was to assess the effectiveness of the Iron lung and negative pressure respiratory support for this indication and to establish its role in the context of other existing therapies at the time. Eichel produced his review and data as the Inaugural Dissertation towards his medical degree from the the University of Zurich, published in 1951. The dissertation was written in German and first translated into English in 2014. The current paper explores the findings of the dissertation and explains why there has been the transition to techniques of respiratory support today. It includes a biography of Dr F. N. Eichel and an update on the current status of poliomyelitis. The original dissertation was found in the home of Nandor's son and was of great interest to the current authors, Nandor's granddaughter and her colleague.

Purpose: X-ray findings are described, which are typical for injuries due to conventional weapons. It is intended to demonstrate that radiographs can show findings characteristic for weapons. Material and method: The radiograms have been collected in Vietnam, Croatia, Serbia, Bosnia, Chad, Iran, Afghanistan, USA, Great Britain, France, Israel, Palestine, and Germany. Results: Radiograms of injuries due to hand grenades show their content (globes) and cover fragments. The globes are localized regionally in the victim's body. Survivors of cluster bombs show singular or few globes; having been hit by many globes would have been lethal. Shotguns produce characteristic distributions of the pallets and depth of penetration different from those of hand grenades and cluster bombs; cover fragments are lacking. Gunshot wounds (GSW) can be differentiated in those to low velocity bullets, high velocity projectiles, and projectiles, which disintegrate on impact. The radiogram furnishes the information about a dangerous shock and helps to recognize the weapon. Radiograms of victims of explosion show fragments and injuries due to the blast, information valid for therapy planning and prognosis. The radiogram shows details which can be used in therapy, forensic medicine and in war propaganda - examples could be findings typical for cluster bombs and for dumdum bullets; it shows the cruelty of the employment of weapons against humans and the conflict between the goal of medical care and those of military actions. Conclusion: Radiographs may show, which weapon has been employed; they can be read as war reports.

Nuclear weapons complex: What went wrong?

International Nuclear Information System (INIS)

Martin, J.E.

1991-01-01

The nuclear weapons complex has generated significant volumes of radioactive wastes dating back to the 1940s. Such wastes included transuranic radioisotopes-for example, plutonium-generated as byproducts of the operations. Most of these wastes at the major disposal site were not classified in the same way nuclear wastes are classified today; the definitions of high- and low-level wastes have changed over time, and, in the case of the latter, different classes have been established that determine methods for disposal and handling. Waste disposal was not a high priority during World War II. After the war, however; resources were not committed to either waste-disposal research or the development of a national waste management policy. AEC's failure to develop a national policy on radioactive waste disposal is easier to understand than to excuse. The disposal problem parallels the chemical waste disposal situation, where there were no federal and few state laws regulating chemical waste disposal until 1976, following publicity about Love Canal. This same story has been repeated for radioactive and mixed wastes and facility safety at the nation's nuclear weapon sites

Vulnerability assessment of a space based weapon platform electronic system exposed to a thermonuclear weapon detonation

Science.gov (United States)

Perez, C. L.; Johnson, J. O.

Rapidly changing world events, the increased number of nations with inter-continental ballistic missile capability, and the proliferation of nuclear weapon technology will increase the number of nuclear threats facing the world today. Monitoring these nation's activities and providing an early warning and/or intercept system via reconnaissance and surveillance satellites and space based weapon platforms is a viable deterrent against a surprise nuclear attack. However, the deployment of satellite and weapon platform assets in space will subject the sensitive electronic equipment to a variety of natural and man-made radiation environments. These include Van Allen Belt protons and electrons; galactic and solar flare protons; and neutrons, gamma rays, and x-rays from intentionally detonated fission and fusion weapons. In this paper, the MASH vl.0 code system is used to estimate the dose to the critical electronics components of an idealized space based weapon platform from neutron and gamma-ray radiation emitted from a thermonuclear weapon detonation in space. Fluence and dose assessments were performed for the platform fully loaded, and in several stages representing limited engagement scenarios. The results indicate vulnerabilities to the Command, Control, and Communication bay instruments from radiation damage for a nuclear weapon detonation for certain source/platform orientations. The distance at which damage occurs will depend on the weapon yield (n,(gamma)/kiloton) and size (kilotons).

Political accountability and autonomous weapons

Directory of Open Access Journals (Sweden)

James Igoe Walsh

2015-09-01

Full Text Available Autonomous weapons would have the capacity to select and attack targets without direct human input. One important objection to the introduction of such weapons is that they will make it more difficult to identify and hold accountable those responsible for undesirable outcomes such as mission failures and civilian casualties. I hypothesize that individuals can modify their attribution of responsibility in predicable ways to accommodate this new technology. The results of a survey experiment are consistent with this; subjects continue to find responsible and hold accountable political and military leaders when autonomous weapons are used, but also attribute responsibility to the designers and programmers of such weapons.

Disposition of excess weapons plutonium from dismantled weapons

International Nuclear Information System (INIS)

Jardine, L.J.

1997-01-01

With the end of the Cold War and the implementation of various nuclear arms reduction agreements, US and Russia have been actively dismantling tens of thousands of nuclear weapons. As a result,large quantities of fissile materials, including more than 100 (tonnes?) of weapons-grade Pu, have become excess to both countries' military needs. To meet nonproliferation goals and to ensure the irreversibility of nuclear arms reductions, this excess weapons Pu must be placed in secure storage and then, in timely manner, either used in nuclear reactors as fuel or discarded in geologic repositories as solid waste. This disposition in US and Russia must be accomplished in a safe, secure manner and as quickly as practical. Storage of this Pu is a prerequisite to any disposition process, but the length of storage time is unknown. Whether by use as fuel or discard as solid waste, disposition of that amount of Pu will require decades--and perhaps longer, if disposition operations encounter delays. Neither US nor Russia believes that long-term secure storage is a substitute for timely disposition of excess Pu, but long-term, safe, secure storage is a critical element of all excess Pu disposition activities

2012-07-01

Full Text Available In martial tradition, spears and lances have always played a very important role as main weapons on the battlefield, as exemplified through Iranian military history. Its reach and cheap production were important factors for establishing formations of soldiers equipped with spears and lances. Additionally, the combat techniques of spears and lances were relatively easy and one could learn the techniques of spearfighting and lancefighting much easier than other weapons, such as swords. The first part of the article describes some types of spears and lances that were used in the Islamic period of Iran. Then the method of carrying a spear/lance is analyzed and additionally some offensive techniques, feinting techniques, attacking techniques to the animal carrying the opponent, and defensive techniques using spears/lances are described as documented by Persian manuscripts.

US and Russia face urgent decisions on weapons plutonium

International Nuclear Information System (INIS)

Hileman, B.

1994-01-01

Surplus plutonium poses a ''clear and present danger to national and international security,'' warns a National Academy of Sciences (NAS) study released in January, titled ''The Management and Disposition of Excess Weapons Plutonium.'' Over the past few years, many different methods of disposing of plutonium have been proposed. They range from shooting it into the Sun with missiles, to deep-seabed disposal, to fissioning it within a new generation of nuclear reactors. The NAS report rejects most of the methods suggested so far, but does recommend pursuing two of the options. One is to incorporate the plutonium in mixed-oxide fuel, a mixture of plutonium and uranium oxides, and use it to fuel commercial nuclear reactors. The other is to mix the plutonium with high-level waste and molten glass and mold the resulting material into large glass logs for eventual geologic disposal. Both are discussed here. The panel that wrote the NAS study is a standing committee called the Committee on International Security ampersand Arms Control. It suggests steps that should be taken now to guard supplies of plutonium removed from weapons. One step is bilateral US-Russian monitoring of warhead dismantlement. Others include setting up secure interim storage for the fissile materials and establishing an international monitoring system to verify the stockpiles and ensure that materials are not withdrawn for use in new weapons. The panel also urges Russia to stop producing fissile weapons materials and both countries to commit a very large fraction of their plutonium and highly enriched uranium from dismantled weapons to nonaggressive uses. The US and Russia have already made initial moves to accomplish these goals but have not fully implemented any of them

Verification of Chemical Weapons Destruction

International Nuclear Information System (INIS)

Lodding, J.

2010-01-01

The Chemical Weapons Convention is the only multilateral treaty that bans completely an entire category of weapons of mass destruction under international verification arrangements. Possessor States, i.e. those that have chemical weapons stockpiles at the time of becoming party to the CWC, commit to destroying these. All States undertake never to acquire chemical weapons and not to help other States acquire such weapons. The CWC foresees time-bound chemical disarmament. The deadlines for destruction for early entrants to the CWC are provided in the treaty. For late entrants, the Conference of States Parties intervenes to set destruction deadlines. One of the unique features of the CWC is thus the regime for verifying destruction of chemical weapons. But how can you design a system for verification at military sites, while protecting military restricted information? What degree of assurance is considered sufficient in such circumstances? How do you divide the verification costs? How do you deal with production capability and initial declarations of existing stockpiles? The founders of the CWC had to address these and other challenges in designing the treaty. Further refinement of the verification system has followed since the treaty opened for signature in 1993 and since inspection work was initiated following entry-into-force of the treaty in 1997. Most of this work concerns destruction at the two large possessor States, Russia and the United States. Perhaps some of the lessons learned from the OPCW experience may be instructive in a future verification regime for nuclear weapons. (author)

An NDT presupposes a fundamental commitment by all parties to its final objective and hence requires a high and sustained level of confidence amongst all states concerned. The appropriate format for an Nuclear Disarmament Treaty (NDT) would probably be a multilateral treaty open to all states. The treaty must necessarily include the five nuclear weapon states and a procedure would have to be found for securing the ratification of the threshold states without conferring upon them the status of nuclear weapon states. While the IAEA may well be able to carry out the safeguards tasks required by an NDT it would probably be necessary to establish a new international organization to verify the elimination of all nuclear weapons. The experience of UNSCOM and the IAEA in Iraq, and of the IAEA in the DPRK, have shown how difficult the verification of international obligations is in the absence of a commitment to disarm, while the experience of the INF and START treaties, and of the IAEA in South Africa have shown how much simpler it is when the parties concerned are fully committed to the process. Verifying and safeguarding an NDT would be largely an extrapolation of activities already carried out by the nuclear weapon states under the INF and START treaties and by the IAEA in the routine application of safeguards as well as in its less routine work in Iraq, South Africa and the DPRK. Both the verification and safeguarding tasks would be made very much easier if it were possible to bring down to a few hundred the number of nuclear warheads remaining in the hands of any avowed nuclear weapon state, and to conclude a cutoff convention. Experience is needed to show whether the additional safeguards authority accorded to the IAEA by 'programme 93+2' will enable it to effectively safeguard the facilities that would be decommissioned as a result of an NDT and those that would remain in operation to satisfy civilian needs. Subject to this rider and on condition that the IAEA

Weapons of mass destruction - current security threat

2005-01-01

This publication brings a complex and comprehensive view of the weapons of mass destruction phenomenon in the context of present military and political situation. It emphasizes the threat posed by proliferation of these destructive devices and their carriers as well as the threat present in their possession by unpredictable totalitarian regimes or terrorist groups. The publication is structured into four basic parts: Introduction Into The Topic, Nuclear Weapons, Chemical Weapons and Biological Weapons. The Introduction reflects the latest developments on the field of military technologies, which lead to the development of new destructive devices with characteristics comparable to basic types of WMDs - nuclear, chemical and biological. Based on the definition of WMD as 'weapon systems with enormous impact causing mass destruction, population, equipment and material losses', the modern mass destruction devices are assorted here, such as ecological, radiological and beam weapons, aerosol and container intelligent ammunition, the outburst of dangerous chemical substances from infrastructure, non-conventional weapons and military devices. The Nuclear Weapons part depicts the most destructive device of mass destruction mankind ever invented in close detail. It maps the history of most significant discoveries in nuclear physics, development and construction of the first nuclear weapons, accumulation of nuclear warheads and their carriers in the Cold war era, attempts of nuclear disarmament and reducing the number of nuclear weapons in possession of superpowers and their proliferation in the world's crisis regions including North Korea and Iran. The chapters devoted to theoretical grounds and physical principles of nuclear and thermonuclear weapons' functioning, the main categories and types, as well as destructive effects and consequences of use contain an adequate mathematical apparatus. This chapter's conclusion brings the overview of nuclear armament of states that

Global strike hypersonic weapons

Beginning in the 1940's, the United States has pursued the development of hypersonic technologies, enabling atmospheric flight in excess of five times the speed of sound. Hypersonic flight has application to a range of military and civilian applications, including commercial transport, space access, and various weapons and sensing platforms. A number of flight tests of hypersonic vehicles have been conducted by countries around the world, including the United States, Russia, and China, that could lead the way to future hypersonic global strike weapon systems. These weapons would be especially effective at penetrating conventional defenses, and could pose a significant risk to national security.

For a convention for nuclear weapon elimination

International Nuclear Information System (INIS)

2008-03-01

This document contains two texts linked with the project of an international convention for the elimination of nuclear weapons (the text of this project has been sent to the UN General Secretary and is part of an international campaign to abolish nuclear weapons, ICAN). These two texts are contributions presented in London at the Global Summit for a Nuclear Weapon-free World. The first one calls into question the deterrence principle and the idea of a nuclear weapon-based security. It calls for different forms of action to promote a nuclear weapon-free world. The second text stresses the role and the responsibility of states with nuclear weapons in nuclear disarmament and in the reinforcement of the nuclear non proliferation treaty (NPT)

Igniting the Light Elements: The Los Alamos Thermonuclear Weapon Project, 1942-1952

Fitzpatrick, Anne C. [Virginia Polytechnic Inst. and State Univ. (Virginia Tech), Blacksburg, VA (United States)

1999-07-01

The American system of nuclear weapons research and development was conceived and developed not as a result of technological determinism, but by a number of individual architects who promoted the growth of this large technologically-based complex. While some of the technological artifacts of this system, such as the fission weapons used in World War II, have been the subject of many historical studies, their technical successors--fusion (or hydrogen) devices--are representative of the largely unstudied highly secret realms of nuclear weapons science and engineering. In the postwar period a small number of Los Alamos Scientific Laboratory's staff and affiliates were responsible for theoretical work on fusion weapons, yet the program was subject to both the provisions and constraints of the US Atomic Energy Commission, of which Los Alamos was a part. The Commission leadership's struggle to establish a mission for its network of laboratories, least of all to keep them operating, affected Los Alamos's leaders' decisions as to the course of weapons design and development projects. Adapting Thomas P. Hughes's ''large technological systems'' thesis, I focus on the technical, social, political, and human problems that nuclear weapons scientists faced while pursuing the thermonuclear project, demonstrating why the early American thermonuclear bomb project was an immensely complicated scientific and technological undertaking. I concentrate mainly on Los Alamos Scientific Laboratory's Theoretical, or T, Division, and its members' attempts to complete an accurate mathematical treatment of the ''Super''--the most difficult problem in physics in the postwar period--and other fusion weapon theories. Although tackling a theoretical problem, theoreticians had to address technical and engineering issues as well. I demonstrate the relative value and importance of H-bomb research over time in the postwar era to

An improved 82 Sr- 82 Rb radioisotope generator system, based upon the complexing ion exchange resin Chelex-100, has been developed. Columns of this material can be easily and rapidly milked, and the Rb-Sr separation factor for a fresh generator was found to be greater than 10 7 . Approximately 80 percent of the 82 Rb present was delivered in a 15-ml volume of aqueous 0.2 M NH 4 Cl solution. After more than 6 liters of eluant had been put through the generator, the Rb-Sr separation factor was still observed to be greater than 10 5 , and no unusual strontium breakthrough behavior was seen in the system over nearly three 82 Sr half lives. 2 claims, no drawings

Total Ozone Data From a European Network 1951-1957

Soon after its foundation in 1948, the International Ozone Commission (IOC) established a total ozone network in Europe, together with the Gassiot Committee of the Royal Socitey, UNESCO, the London Meteorological Office and national services. The network was built-up in 1950 with Dobson spectrophotometers equipped with photomultipliers, which were calibrated in Oxford before shipping to the stations. In 1957, some of the stations became part of the network of the IGY, and these data can be found today at the WOUDC. The earlier data were compiled and archived in Oxford by the secretary of the IOC, Charles Normand, but have never been published and only rarely appeared in the scientific literature [Normand, QJRMS 67 (1951) 474 and QJRMS 69 (1953) 39]. The copies of the data sheets stored at UK Met Office [MO/19/3/9 Part I] comprise daily values from the following stations/time periods: Aarhus (DK, 6/52-12/59, Dobson #41), Aldergrove (UK, 6/52-4/57, #35?), Arosa (CH, 6/52-12/58 #15), Cagliari/Elmas (IT, 12/54-5/59, #48), Camborne (UK, 1/52-12/59, #32), Eskdalemuir (UK, 9/57-12/59, #35), Hemsby (UK, 6/52-9/55), Lerwick (UK, 6/52-12/59, #7), Magny les Hameaux (FR, 1/55-9/57, #49?), Messina (IT, 7/54-6/58, #46), Oxford (UK, 6/52-12/59, #1), Paris/Montsouris (FR, 10/57-8/58, #49), Reykjavik (IS, 6/52-10/59, #50), Rome/Vigna di Valle (IT, 4/54-12/59 #47), Santa Maria/Azores (ES, 2/53-7/56, #13), Spitzbergen (NO, 11/50-7/58, #8), Tromsoe (NO, 6/52-5/59, #14), Uccle (BE, 6/52-12/58, #40), and Uppsala (SE, 6/52-12/58, #30). These data could be useful to supplement the currently available total ozone measurement series. Together with existing meteorological data, they enable us to study the relation between atmospheric circulation and total ozone in a chemically largely unperturbed time period. The daily values from 1951 to 1957 have now been digitized. Using appropriate statistical methods, the quality of each series will be addressed. The data will be homogenized and re

Changing annual incidence of hypothyroidism after iodine-131 therapy for hyperthyroidism, 1951-1975

International Nuclear Information System (INIS)

Holm, L.E.

1982-01-01

The incidence of hypothyroidism was analyzed in 4,553 hyperthyroid patients treated with I-131 between 1951 and 1975. The average annual rate of hypothyroidism during the first 7 yr after therapy increased continuously for each 5-yr period of treatment, from 3.6% for patients treated between 1951 and 1955 to 7.7% for patients treated during the period from 1971 though 1975 (p less than 0.001). The increase in the incidence of hypothyroidism was seen before the introduction of TSH assays and when allowance was made for thyroid gland size, the age of the patient, and the experience of the radiotherapist. The use of TSH assays has probably resulted in an earlier recognition of hypothyroidism, which may explain why the most marked rise in the incidence of hypothyroidism was observed after the introduction of TSH assays

2017-11-01

The use of chemical or biological weapons, whether by a State or terrorists, continues to be a serious security concern. Both types of weapons are prohibited by multilateral treaties that have very broad membership, but both the Biological Weapons Convention and the Chemical Weapons Convention are facing major challenges. In particular, the continued use of chemical weapons in the Syrian civil war by government forces risks eroding the norm against the use of such weapons. This paper briefly explore the recent history of efforts to constrain chemical and biological weapons and outlines challenges for the future.

Nuclear experts and nuclear weapons proliferation

International Nuclear Information System (INIS)

Mueller, H.

1979-01-01

In Germany the issue of nuclear weapons proliferation has attracted scant attention. Most potential nuclear weapon states are important trade partners of the FRG and, since further proliferation of nuclear weapons could worsen conflicts involving these, it should be in the FRG's interest to limit proliferation. The security of the FRG is also dependent on the common interest of the great powers to avoid nuclear war. The contradictory positions of Usa and the USSR on nuclear weapons policy regarding themselves and non-nuclear weapon states encourages less developed countries to see nuclear weaponry as useful. The NPT and IAEA safeguards have only limited inhibiting effect. The nuclear export policy of the FRG has been dominated by short term economic advantage, neglecting the negative long term effects of decreased political stability. The FRG should formulate a policy based on self-restraint, positive stimuli and extension of controls, using its economic strength to deter proliferation. (JIW)

Reframing the debate against nuclear weapons

International Nuclear Information System (INIS)

Tyson, Rhianna

2005-01-01

'Some 35,000 nuclear weapons remain in the arsenals of the nuclear powers, with thousands still deployed on hair-trigger alert. Whatever rationale these weapons may once have had has long since dwindled. Political, moral, and legal constraints on actually using them further undermine their strategic utility without, however, reducing the risks of inadvertent war or proliferation. The objective of nuclear non-proliferation is not helped by the fact that the nuclear weapon States continue to insist that those weapons in their hands enhance security, while in the hands of others they are a threat to world peace. If we were making steady progress towards disarmament, this situation would be less alarming. Unfortunately, the reverse is true.' - United Nations Secretary-General Kofi Annan. 'Something is wrong with the nuclear disarmament and non-proliferation regime. Although seemingly well-equipped with an arsenal of legal and political mechanisms, such as the Nuclear Non-Proliferation Treaty (NPT), the 1996 Advisory Opinion of the International Court of Justice (ICJ), decades' worth of General Assembly (GA) resolutions and even a recent slew of ad-hoc, plurilateral initiatives such as the Proliferation Security Initiative, the regime created to prevent the catastrophe of nuclear war remains inadequate. This insufficiency is even starker when viewed in relation to the regimes controlling other weapons of mass destruction. Despite its own challenges, the Organization for the Prohibition on Chemical Weapons remains relatively well-funded and well-situated to facilitate the implementation of the Chemical Weapons Convention (CWC). Even the Biological and Toxin Weapons Convention (BTWC), while still lacking the necessary verification mechanisms, has managed to effectively criminalize not just the use and threat of use of biological weapons, but also their production, development and stockpiling. Meanwhile, the anti-nuclear regime seems to be faltering. Progress made in

Bioterrorism: toxins as weapons.

Science.gov (United States)

Anderson, Peter D

2012-04-01

The potential for biological weapons to be used in terrorism is a real possibility. Biological weapons include infectious agents and toxins. Toxins are poisons produced by living organisms. Toxins relevant to bioterrorism include ricin, botulinum, Clostridium perfrigens epsilson toxin, conotoxins, shigatoxins, saxitoxins, tetrodotoxins, mycotoxins, and nicotine. Toxins have properties of biological and chemical weapons. Unlike pathogens, toxins do not produce an infection. Ricin causes multiorgan toxicity by blocking protein synthesis. Botulinum blocks acetylcholine in the peripheral nervous system leading to muscle paralysis. Epsilon toxin damages cell membranes. Conotoxins block potassium and sodium channels in neurons. Shigatoxins inhibit protein synthesis and induce apoptosis. Saxitoxin and tetrodotoxin inhibit sodium channels in neurons. Mycotoxins include aflatoxins and trichothecenes. Aflatoxins are carcinogens. Trichothecenes inhibit protein and nucleic acid synthesis. Nicotine produces numerous nicotinic effects in the nervous system.

Weapons material and the commercial fuel cycle

Steyn, J.J.

1993-01-01

In 1991, the United States and the former USSR had arsenals of ∼18,000 and 27,200 nuclear weapons, respectively. Approximately 10,000 of the US and 13,000 of the former USSR weapons were in the strategic category, and the remainder were tactical weapons. The dramatic changes in the political climate between the United States and the republics of the former USSR have resulted in the signing of the Strategic Arms Reduction Treaty (START I and II), agreements to substantially reduce nuclear weapons arsenals. Tactical weapons have already been collected in Russia, and strategic weapons are to be collected by the end of 1994. The major issues in accomplishing the treaty reductions appear to be funding, transport safety, storage capacity, and political issues between Russia and Ukraine because the latter seems to be using its weapons for political leverage on other matters. Collectively, the US and former USSR warhead stockpiles contain tremendous inventories of high-enriched uranium and weapons-grade plutonium which if converted to light water reactor fuel would equate to an enormous economic supply of natural uranium, conversion services, and enrichment separative work. The potential for this material entering the light water reactor fuel marketplace was enhanced in July 1992, when the two US industrial companies, Nuclear Fuel Services and Allied-Signal, announced that they had reached a preliminary agreement with the Russian ministry, Minatom, and the Russian Academay of Sciences to convert Russian high-enriched uranium to low-enriched uranium

Effects of Weapons on Aggressive Thoughts, Angry Feelings, Hostile Appraisals, and Aggressive Behavior: A Meta-Analytic Review of the Weapons Effect Literature.

Science.gov (United States)

Benjamin, Arlin J; Kepes, Sven; Bushman, Brad J

2017-09-01

Guns are associated with aggression. A landmark 1967 study showed that simply seeing a gun can increase aggression-called the "weapons effect." This meta-analysis integrates the findings of weapons effect studies conducted from 1967 to 2017. It includes 162 effect-size estimates from 78 independent studies involving 7,668 participants. The theoretical framework used to explain the weapons effect was the General Aggression Model (GAM), which proposes three routes to aggression-cognitive, affective, and arousal. The GAM also proposes that hostile appraisals can facilitate aggression. As predicted by the GAM, the mere presence of weapons increased aggressive thoughts, hostile appraisals, and aggression, suggesting a cognitive route from weapons to aggression. Weapons did not significantly increase angry feelings. Only one study tested the effects of weapons on arousal. These findings also contribute to the debate about social priming by showing that incidental exposure to a stimulus (weapon) can affect subsequent related behavior (aggression).

Characterising the online weapons trafficking on cryptomarkets.

Weapons related webpages from nine cryptomarkets were manually duplicated in February 2016. Information about the listings (i.e. sales proposals) and vendors' profiles were extracted to draw an overview of the actual online trafficking of weapons. Relationships between vendors were also inferred through the analysis of online digital traces and content similarities. Weapons trafficking is mainly concentrated on two major cryptomarkets. Besides, it accounts for a very small proportion of the illicit trafficking on cryptomarkets compared to the illicit drugs trafficking. Among all weapon related listings (n=386), firearms only account for approximately 25% of sales proposal since the proportion of non-lethal and melee weapons is important (around 46%). Based on the recorded pseudonyms, a total of 96 vendor profiles were highlighted. Some pseudonyms were encountered on several cryptomarkets, suggesting that some vendors may manage accounts on different markets. This hypothesis was strengthened by comparing pseudonyms to online traces such as PGP keys, images and profiles descriptions. Such a method allowed to estimate more accurately the number of vendors offering weapons across cryptomarkets. Finally, according to the gathered data, the extent of the weapons trafficking on the cryptomarkets appear to be limited compared to other illicit goods. Copyright © 2017 Elsevier B.V.

Based on the analysis of the long process of negotiations for implementing the Treaty of Tlatelolco and its history during the last three decades, especially its influence on other regions of the world for stimulating the creation of new nuclear-weapon-free zones, the following conclusions were drawn: nuclear danger still persists; the end of Cold War implies the end of a nuclear threat; the nuclear fear should not become nuclear complacency and be accepted by international community; common security as the goal of international community should be recognised and definitive abolition of nuclear weapons should be sought; the Treaty of Tlatelolco represents the cornerstone for creating new nuclear-weapon-free zones; Treaties of Tlatelolco, Rarotonga, Bangkok and Pelindaba should be examples to be followed by other regions and groups of countries for creating new nuclear-weapon-free zones which should be recognised as very important phase in achieving a nuclear-weapon-free world and means for attaining an international regime of non-proliferation of weapons for mass destruction

China's mixed signals on nuclear weapons

International Nuclear Information System (INIS)

Fieldhouse, R.

1991-01-01

Ultimately, it is nuclear whether the Chinese leadership has made up its collective mind on practical nuclear weapons. It is known from Chinese official sources, including articles in Communist Party and military publications and histories of the Chinese nuclear program, that an internal debate has proceeded for more than two decades, punctuated by occasional nuclear exercises or low-yield warhead tests. But China presumably has less reason now to pursue development of tactical nuclear weapons than in previous decades: relations with the Soviet Union have improved and military confrontation has eased; China's relations with India and Vietnam are also improving. The decision may already have been made, however, and the weapons built. The mystery surrounding Chinese tactical nuclear weapons is itself interesting, but it is also symbolic of the difficulty of understanding China's nuclear weapons program and policies. The West has accumulated a considerable body of knowledge about China's nuclear forces, especially historical material. But important aspects of China's nuclear behavior and its future as a nuclear power are hard to discern. A key question is China's future role in the spread of nuclear-capable weapons to other countries. China might add to international efforts to stem the proliferation of nuclear related technology, or it might become the world's missile merchant. It could make a constructive contribution to arms control efforts in general, or it could act as a spoiler

Full text: It is a great honour for me to address this Conference for a Nuclear-Weapons-Free World. Astana is a highly appropriate venue for this Conference. Kazakhstan has made a very important contribution to nuclear non-proliferation and disarmament. Under the leadership of President Nursultan Nazarbayev, Kazakhstan renounced the nuclear weapons which it inherited from the Soviet Union and closed the Semipalatinsk Nuclear Test Site, where over 450 underground and atmospheric nuclear tests had been conducted. It joined the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) as a non-nuclear-weapon State and has concluded both a safeguards agreement and an additional protocol with the IAEA. Kazakhstan played a significant role in establishing a nuclear-weapon-free zone in Central Asia in 2009. The treaty creating this nuclear-weapon-free zone established an important precedent as it is the only arms control treaty to date that requires its parties to bring into force an additional protocol to their IAEA safeguards agreements. The treaty, which was supported by the IAEA, forbids the development, manufacture, stockpiling, acquisition or possession of any nuclear explosive device within the zone. Peaceful uses of nuclear energy are permitted if placed under enhanced IAEA safeguards. The treaty also requires Parties to meet international standards regarding security of nuclear facilities. This is intended to reduce the risk of nuclear terrorism and prevent smuggling of nuclear and radioactive materials in the region. Today, the scientific and technical facilities at Semipalatinsk are being converted to peaceful uses under the jurisdiction of the National Nuclear Centre of the Republic of Kazakhstan. IAEA is pleased to have assisted in this work. Shutting down the nuclear test range at Semipalatinsk sends a strong signal of support for the nuclear non-proliferation and disarmament regime. It contributes both directly and symbolically to the goals of the

The Regulation of the Possession of Weapons at Gatherings

Directory of Open Access Journals (Sweden)

Pieter du Toit

2013-12-01

Full Text Available The Dangerous Weapons Act 15 of 2013 provides for certain prohibitions and restrictions in respect of the possession of a dangerous weapon and it repeals the Dangerous Weapons Act 71 of 1968 as well as the different Dangerous Weapons Acts in operation in the erstwhile TBVC States. The Act also amends the Regulation of Gatherings Act 205 of 1993 to prohibit the possession of any dangerous weapon at a gathering or demonstration. The Dangerous Weapons Act provides for a uniform system of law governing the use of dangerous weapons for the whole of South Africa and it furthermore no longer places the onus on the individual charged with the offence of the possession of a dangerous weapon to show that he or she did not have any intention of using the firearm for an unlawful purpose. The Act also defines the meaning of a dangerous weapon. According to our court’s interpretation of the Dangerous Weapons Act 71 of 1968 a dangerous weapon was regarded as an object used or intended to be used as a weapon even if it had not been designed for use as a weapon. The Act, however, requires the object to be capable of causing death or inflicting serious bodily harm if it were used for an unlawful purpose. The possession of a dangerous weapon, in circumstances which may raise a reasonable suspicion that the person intends to use it for an unlawful purpose, attracts criminal liability. The Act also provides a useful set of guidelines to assist courts to determine if a person charged with the offence of the possession of a dangerous weapon had indeed intended to use the weapon for an unlawful purpose. It seems, however, that the Act prohibits the possession of a dangerous weapon at gatherings, even if the person carrying the weapon does not intend to use it for an unlawful purpose. The state will, however, have to prove that the accused had the necessary control over the object and the intention to exercise such control, as well as that the object is capable of

New Weapons and the Arms Race

In speaking about technologies that could further animate the weapons competition between the United States and the U.S.S.R., it would be useful to distinguish between technologies that have already been incorporated into specific weapons systems, and new technologies that are of a generic nature, can be used in a variety of applications, adn can best be described by the tasks that they can perform rather than any specific weapons application. Let me begin with the latter class.

results, would be very useful. By far the hardest verification problem facing nuclear disarmament is that of illicit acquisition or retention of nuclear weapons. This challenge would benefit from further study by each of the nuclear weapon states and as many other nations as are willing to devote resources to supporting nuclear disarmament. As is the case for all disarmament agreements, an industrialised country could, in theory, circumvent verification measures included in a nuclear weapons convention. But a verification regime should reduce the uncertainties in disarmament, and demonstrate an open and co-operative approach to creating a nuclear weapon-free world. Verification is just one of the many possible interlocking measures in an international disarmament treaty, and should not be seen as the single most important. While verification regimes have an important role to play in encouraging the participation of states in international disarmament treaties, and in ensuring that these treaties are effective, they are only part of a wider disarmament process. Since nuclear weapons might be eliminated over decades, it is relevant to consider the main respects in which the possibilities for verifying nuclear disarmament could change on such a timescale. Two important trends, in this respect, are those towards greater openness in the world, and towards improving technological verification capabilities. Greater openness at nuclear facilities is of particular importance in building international confidence in disarmament. Whenever possible, national research programmes on verification and other aspects of arms control, non-proliferation and disarmament, should involve international collaboration, since this could be a primary means of increasing openness, as well as of perfecting verification techniques. Openness at nuclear weapons establishments, including regular interactions between nuclear weapons scientists from different countries, should promote societal verification

Nuclear Weapons in Russia's approach to conflict

International Nuclear Information System (INIS)

Johnson, Dave

2016-11-01

President Putin has moved nuclear weapons to the foreground of the European security landscape. New risks and dangers arise from the apparent coupling of nuclear weapons capabilities with Moscow's revanchist and irredentist foreign and defence policies toward its neighbours. Nuclear weapons are the central feature and capstone capability in Russia's evolving concept of strategic deterrence and are important tools for achieving Russia's geopolitical aims. Russian thinking on the role and place of nuclear weapons in upholding national security and in achieving strategic aims is reflected in military policy, force structure and posture, and exercises and operations. Russia's political and military leaders are not only re-conceptualising the role of nuclear weapons. They are also building the military capabilities that can credibly threaten the calibrated employment of nuclear weapons for deterrence, de-escalation and war-fighting from the regional to large-scale and global levels of conflict. New and still developing concepts for the employment of conventional long-range precision weapons in tandem with nuclear weapons for regional deterrence and containment of local and regional conflicts add volatility to the regional tensions and uncertainties created by recent Russian aggression. Russia's reliance upon integrated conventional and nuclear capabilities in reasserting its influence in its perceived sphere of special interest, intended to contain conflicts at a manageable level, could actually increase the risk of the potential employment of nuclear weapons. NATO nations collectively, and the three NATO nuclear powers (Great Britain, France, and the United States) individually, have recognized this new reality and have begun to adapt to it. In that context, the aim of this paper is to elaborate a clearer understanding of the place and role of nuclear weapons in Russia's approach to conflict, based on nuclear-related policy statements and military-theoretical writing

This article describes a brief history of chemical warfare, which culminated in the signing of the Chemical Weapons Convention. It describes the current level of chemical weapons and the risk of using them. Furthermore, some traditional technology for the development of chemical weapons, such as increasing toxicity, methods of overcoming chemical protection, research on natural toxins or the introduction of binary technology, has been described. In accordance with many parameters, chemical weapons based on traditional technologies have achieved the limit of their development. There is, however, a big potential of their further development based on the most recent knowledge of modern scientific and technical disciplines, particularly at the boundary of chemistry and biology. The risk is even higher due to the fact that already, today, there is a general acceptance of the development of non-lethal chemical weapons at a technologically higher level. In the future, the chemical arsenal will be based on the accumulation of important information from the fields of chemical, biological and toxin weapons. Data banks obtained in this way will be hardly accessible and the risk of their materialization will persist.

Issues of weapons of mass destruction non-proliferation in Tajikistan

International Nuclear Information System (INIS)

Mirsaidov, U.M.

2010-01-01

This article is devoted to issues of weapons of mass destruction non-proliferation in Tajikistan. Over a period of 20 century, starting from First World War, the weapons of mass destruction arouse serious concern of world community. Geneva protocol of 1925 prohibits the use of chemical and biological weapons. Once nuclear weapon was created, the weapons of mass destruction distributions become the subject of high concern. Besides, during the end of 'cold war', regional conflicts, collapse of Soviet Union, as well as access to sensitive technologies considerably increase the danger of weapons of mass destruction distribution. More than 10 countries have active programs, relating to weapons of mass destruction and, possibly, more than ten countries have potential to start implementing such kinds of programs. Nowadays, trans national organized criminal groups and international terrorist networks are appeared in the world scene, which show interest in obtaining an access to sensitive materials, technologies, weapons and their distribution. After 11 September events, the risk of such weapons of mass destruction components use by such forces for Governments blackmail become real scene, which, despite of low possibility of this threat implementation, could have very serious and disastrous consequences. International community responded to these problems and challenges, basically through the following actions, which is detailed regime development of multilateral international treaties, directed to weapons of mass destruction distribution prevention. Non-proliferation treaty of nuclear weapons, Convention on prohibition of chemical weapons and Convention on prohibition of biological and toxin weapons are some of them. As it is known, Tajikistan signed all these treaties. For different reasons these treaties were subject of serious tests.

Consequences of the Use of Neutron Weapons

International Nuclear Information System (INIS)

Ilijas, B.

1998-01-01

In modern conceptions of the use of nuclear weapons there is a significant role of so called enhanced radiation weapons, also known as neutron weapons. Its most important feature is that all other effects (blast, thermal) are minimized in favour of neutron radiation. Because of the great penetrative capability and biological efficiency, neutron beam is ideal weapon against people in shelters and armoured vehicles. Material goods stay saved and also there is no significant long- term radioactive contamination. After the use of this weapons, which is possible even for tactical tasks on limited area, one must count with great number of people irradiated with doses in wide range - from those enough for instantaneous incapacitation to those which cause only long-term effects. For the purpose of maximal efficiency in this situation, it is necessary to work out plans for dosimetric control, first aid, transport and medical treatment of irradiated people (soldiers and civilians) in war conditions.

1964-02-01

This book is a revision of "The Effects of Nuclear Weapons" which was issued in 1957. It was prepared by the Defense Atomic Support Agency of the Department of Defense in coordination with other cognizant governmental agencies and was published by the U.S. Atomc Energy Commission. Although the complex nature of nuclear weapons effects does not always allow exact evaluation, the conclusions reached herein represent the combined judgment of a number of the most competent scientists working the problem. There is a need for widespread public understanding of the best information available on the effects of nuclear weapons. The purpose of this book is to present as accurately as possible, within the limits of national security, a comprehensive summary of this information.

Why are sexually selected weapons almost absent in females?

Directory of Open Access Journals (Sweden)

Anders BERGLUND

2013-08-01

Full Text Available In sex role reversed species, predominantly females evolve sexually selected traits, such as ornaments and/or weapons. Female ornaments are common and their function well documented in many species, whether sex role reversed or not. However, sexually selected female weapons seem totally absent except for small wing spurs in three jacana species, present in both males and females. This poor female weaponry is in sharp contrast to the situation in species with conventional sex roles: males commonly have evolved sexually selected weapons as well as ornaments. At the same time, females in many taxa have naturally selected weapons, used in competition over resources or in predator defence. Why are sexually selected weapons then so rare, almost absent, in females? Here I briefly review weaponry in females and the function of these weapons, conclude that the near absence of sexually selected weapons begs an explanation, and suggest that costs of sexually selected weapons may exceed costs of ornaments. Females are more constrained when evolving sexually selected traits compared to males, at least compared to those males that do not provide direct benefits, as trait costs reduce a female’s fecundity. I suggest that this constraining trade-off between trait and fecundity restricts females to evolve ornaments but rarely weapons. The same may apply to paternally investing males. Whether sexually selected weapons actually are more costly than sexually selected ornaments remains to be investigated [Current Zoology 59 (4: 564–568, 2013].

Peaceful uses of nuclear weapon plutonium

Burtak, F.

In 1993, the U.S.A. and the CIS signed Start 2 (the Strategic Arms Reduction Treaty) in which they committed themselves the reduce their nuclear weapon arsenals to a fraction of that of 1991. For forty-five years the antagonism between the superpowers had been a dominating factor in world history, determining large areas of social life. When Start 2 will have been completed in 2003, some 200 t of weapon grade plutonium and some 2000 t of highly enriched uranium (Heu) will arise from dismantling nuclear weapons. In the absence of the ideological ballast of the debate about Communism versus Capitalism of the past few decades there is a chance of the grave worldwide problem of safe disposal and utilization of this former nuclear weapon material being solved. Under the heading of 'swords turned into plowshares', plutonium and uranium could be used for peaceful electricity generation. (orig.) [de

Weapons dismantlement issues in independent Ukraine

Zack, N.R.

1995-01-01

The American Association for the Advancement of Science sponsored a seminar during September 1993 in Kiev, Ukraine, titled, ''Toward a Nuclear-Free Future--Barriers and Problems.'' It brought together Ukrainians, Belarusians and Americans to discuss the legal, political, economic, technical, and safeguards and security dimensions of nuclear weapons dismantlement and destruction. US representatives initiated discussions on legal and treaty requirements and constraints, safeguards and security issues surrounding dismantlement, storage and disposition of nuclear materials, warhead transportation, and economic considerations. Ukrainians gave presentations on arguments for and against the Ukraine keeping nuclear weapons, the Ukrainian Parliament's nonapproval of START 1, alternative strategies for dismantling silos and launchers, and economic and security implications of nuclear weapons removal from the Ukraine. Participants from Belarus discussed proliferation and control regime issues. This paper will highlight and detail the issues, concerns and possible impacts of the Ukraine's dismantlement of its nuclear weapons

Emerging nuclear energy systems and nuclear weapon proliferation

International Nuclear Information System (INIS)

Gsponer, A.; Sahin, S.; Jasani, B.

1983-01-01

Generally when considering problems of proliferation of nuclear weapons, discussions are focused on horizontal proliferation. However, the emerging nuclear energy systems currently have an impact mainly on vertical proliferation. The paper indicates that technologies connected with emerging nuclear energy systems, such as fusion reactors and accelerators, enhance the knowledge of thermonuclear weapon physics and will enable production of military useful nuclear materials (including some rare elements). At present such technologies are enhancing the arsenal of the nuclear weapon states. But one should not forget the future implications for horizontal proliferation of nuclear weapons as some of the techniques will in the near future be within the technological and economic capabilities of non-nuclear weapon states. Some of these systems are not under any international control. (orig.) [de

Since the end of the cold war, many people called for the elimination of nuclear weapons. That this decision seems difficult to realize because of the world political environment. Meanwhile the reduction of the nuclear weapons costs and risks believes more than ever a challenge of the international relations and more particularly in the proliferation domain. In this perspective the proliferation fight strategies need to be studied with a special interest in the domain of the alternatives and the possibilities of synergy. (A.L.B.)

As recent theoretical calculations that predicted the onset of superdeformation in the A ≅ 80 region, the 52 Cr( 34 S,2p2n) reaction at 130 MeV beam energy was employed to populate the high-spin states in 82 Sr. The detection system consisted of the ORNL Compton-Suppression Spectrometer System (18 Ge detectors), the Spin Spectrometer, and the 4 φ CsI Dwarf Ball of Washington University. Off-line analysis of the proton-gated data resulted in nearly 170 million Ge-Ge pairs, which were mostly due to the 2p2n channel. A decay scheme extending to spin I=27h has been established. No strong evidence for the presence of superdeformed states in 82 Sr was found in a preliminary analysis of the data. (Author) [es

Democracy, public opinion, and nuclear weapons

International Nuclear Information System (INIS)

Russett, B.

1989-01-01

To the degree that people's fears of nuclear war are deep and pervasive, they become subject to manipulation by cynical or politically utopian promises, whether those promises be to abolish nuclear weapons from the earth or to create a leakproof peace shield (SDI). But the basic yearning for protection could also be mobilized to support serious arms reduction and arms control agreements. Nuclear weapons provide the basis for a vivid form of symbolic politics, perhaps equivalent in foreign policy considerations to the Korean and Vietnam wars during their durations, and in similar ways (although not necessarily as severe) as unemployment does among domestic policy issues. This paper presents survey research directed specifically at the role of public opinion on nuclear imagery (difference between expectation of nuclear war versus any kind of weapon war; willingness to spend on nuclear weapons versus conventional ones or general defense spending) can help in understanding these phenomena

Full Text Available Operating of weapon on the tank is mostly by manually. It is not desired performance for a critical operation. An automatic control system is required to operate the weapon with the target while maintaining the accuracy. In this paper has designed an automatic weapon control system using object image proccessing. Various an image processing methods used to improve the weapon accuracy to obtain the intended target. The method used in digital image processing is the Camshift motion tracking method. This method is compared with the Lucas Canade motion tracking method. This comparison is conducted to found more precise results between the two methods. Results of object image processing are used to control the direction of the weapon that towards the desired goal. The results show that the implementation of the Lucas Canade motion tracking method using fire simulation tools have been successful. The performance of the Lucas Canade motion tracking methods is better than the CamShift method. Using Lucas Canade method for weapon controller is accordance with the purposes.

This report summarizes the findings of a nationwide survey of public perceptions of nuclear weapons in the post-cold war environment. Participants included 1,301 members of the general public, 1,155 randomly selected members of the Union of Concerned Scientists, and 1,226 employees randomly selected from the technical staffs of four DOE national laboratories. A majority of respondents from all three samples perceived the post-cold war security environment to pose increased likelihood of nuclear war, nuclear proliferation, and nuclear terrorism. Public perceptions of nuclear weapons threats, risks, utilities, and benefits were found to systematically affect nuclear weapons policy preferences in predictable ways. Highly significant relationships were also found between public trust and nuclear weapons policy preferences. As public trust and official government information about nuclear weapons increased, perceptions of nuclear weapons management risks decreased and perceptions of nuclear weapons utilities and benefits increased. A majority of respondents favored decreasing funding for: (1) developing and testing new nuclear weapons; (2) maintaining existing nuclear weapons, and (3) maintaining the ability to develop and improve nuclear weapons. Substantial support was found among all three groups for increasing funding for: (1) enhancing nuclear weapons safety; (2) training nuclear weapons personnel; (3) preventing nuclear proliferation; and (4) preventing nuclear terrorism. Most respondents considered nuclear weapons to be a persistent feature of the post-cold war security environment.

Instruments of war weapons and technologies that have changed history

In war, the weapons and technologies employed have direct effects on how battles are waged. When new weapons are introduced, they can dramatically alter the outcomes of warfare-and consequently change the course of history itself. This reference work provides a fascinating overview of the major weapon systems and military technologies that have had a major impact on world history. Addressing weapons as crude as the club used by primitive man to the high-tech weapons of today such as unmanned drones, Instruments of War: Weapons and Technologies That Have Changed History offers nearly 270 profusely illustrated entries that examine the key roles played by specific weapons and identify their success and failures. The book begins with an introductory essay that frames the subject matter of the work and discusses the history of weapons as a whole. The text is concise and accessible to general readers without extensive backgrounds in military history yet provides the detailed information necessary to convey the comp...

The chemical and biological weapon terrorism by the Aum Shnirikyo

International Nuclear Information System (INIS)

Furukawa, K.

2009-01-01

The Aum Shinrikyo, an obscure cult religious group, attacked the Tokyo subways employing sarin gas in March 1995, which was viewed as a mark of a new era in terrorism. The Aum Shinrikyo remains the one empirical example of a religiously motivated cult with an affluent amount of financial and human resources and motivations to use unconventional weapons. The Aum Shinrikyo's leaders included the scientific elite of a young generation as well as former Yakuza members who had close ties with organized crime networks. Aum succeeded in establishing an extensive network to procure weapons, material, and drug, primarily in Russia but also other countries including the United States and even North Korea. Despite the fact that the law enforcement authority had already obtained various pieces of information that reasonably indicated that Aum was producing sarin by late 1994, the law enforcement authority became too cautious to advance its investigation to arrest Aum members until it was too late. Japan's experience with the Aum Shinrikyo's threats provides valuable insights for democratic governments seeking to thwart the deadly plans of religiously motivated non-state actors. It reveals the tremendous difficulties for a democratic society to confront the terrorists who were willing to pursue their deadly 'divine' objectives, especially when the society had no experience to encounter such a threat. This presentation will explain the chemical and biological weapon programs of the Aum Shinrikyo, especially focusing on the following elements: Intention and capability of the Aum Shinrikyo; Weapon systems and mode of attacks, including their target selections; The lessons learned from this case for the prevention and crisis/consequence management n the event of CBW terrorism.

Elle, D.R.; Church, B.W.; Bingham, F.E.

1990-01-01

Concurrently with the first nuclear-weapons tests at the Nevada Test Site (NTS) in 1951, an environmental surveillance and monitoring program was established offsite. Initial emphasis was on tracking fallout clouds and measuring external radiation exposure rates. An environmental research program was also initiated. Establishment of comprehensive programs has facilitated the ability to address issues such as the inventory and distribution of radionuclides in surface soils, reconstruction of offsite population doses, and recognition of areas requiring additional information. We have learned that a successful environmental monitoring program must be flexible and responsive to change; must address public as well as technical and regulatory concerns; and results must be continuously interpreted to ensure that all pathways are considered and the programs are proactive in their approach

Dismantlement and destruction of chemical, nuclear and conventional weapons

1997-01-01

The safe destruction and dismantling of chemical, nuclear and conventional weapons is of fundamental importance to the security of all countries represented in this volume. Expertise in the field is not confined to one country or organisation: all can benefit from each other. There is an ever present danger of proliferation of weapons of mass destruction: approximately two dozen countries have ongoing programmes to develop or acquire such weapons, and many are also gaining the capability to build air-surface delivery systems. But much can be done to prevent proliferation by reducing leakage of materials and know-how and by solving the problems of the destruction of surplus weapons systems, which has now come to be a key issue. In 13 sessions of the workshop attention was paid to (1) Dismantlement and Destruction of Chemical, Nuclear and Conventional Weapons; (2) Status of Implementation of Arms Control Treaties and Voluntary Commitments; (3) National Perspectives on Cooperation in Disarmament; (4) Stocktaking of National and Bilateral Disposal/Destruction Programmes: Chemical Weapons; (5) Stocktaking of National and Bilateral Disposal/Destruction Programmes: Nuclear Weapons; (6) Stocktaking of National and Bilateral Disposal/Destruction Programmes: Conventional Weapons.

Given the fundamental changes in the political context and NATO's perception of nuclear weapons, what role remains for US nuclear weapons in preserving security in Europe? Are US nuclear deployments on the continent still necessary? Is there a requirement for extended deterrence and, if so, does its credibility depend on the continued basing of US nuclear weapons in Europe? And what is the role of arms control in effecting any desirable restructuring in nuclear force postures? In addressing these questions, it becomes clear that US nuclear weapons can now be removed from Europe - they no longer serve the political and military functions they once did

In the next few years, approximately 50 metric tons of weapons-grade plutonium and 150 metric tons of highly-enriched uranium (HEU) may be removed from nuclear weapons in the US and declared excess. These materials represent a significant energy resource that could substantially contribute to our national energy requirements. HEU can be used as fuel in naval reactors, or diluted with depleted uranium for use as fuel in commercial reactors. This paper proposes to use the weapons-grade plutonium as fuel in light water reactors. The first such reactor would demonstrate the dual objectives of producing electrical power and denaturing the plutonium to prevent use in nuclear weapons

Is a nuclear weapon-free world desirable?

International Nuclear Information System (INIS)

Tertrais, Bruno

2009-01-01

In this article, the author shows that a nuclear weapon-free world would probably be more dangerous than today's world because benefits of the existence of nuclear weapons are probably more important that the risks related to their existence. He outlines that nuclear deterrence has been very efficient for these last 65 years. He states that the disappearance of nuclear weapons could be envisaged only after a large transformation of safety conditions, but that such transformations are actually not at all under way. It would indeed require peaceful and democratic world governance

ENSINO DE ASTRONOMIA NO BRASIL - 1850 A 1951 - UM OLHAR PELO COLÉGIO PEDRO II

Full Text Available The teaching of Astronomy in Brazil is analyzed in the 18 programs of the Pedro II School, relative to the 1841 to 1951 reforms, based on the understanding that the curriculum is the result of a process made up of conflicts and disputes between different traditions and social conceptions. The Astronomy was first identified in the Cosmography subject, although it is absent from the curricula in some periods (1856/58 and 1951 and returns, at other times, included in subjects like Geography and/or Physics (e.g. 1858 and 1931. The non-linearity of the temporal evolution in the curriculum is also observed in the maintenance of subjects such as seasons or eclipses in all the reforms and in the disconnected absence of subject matter like the methods for the star observation or the characterization of the Sun in some of them.

Is further proliferation of nuclear weapons irrelevant to US national security

International Nuclear Information System (INIS)

Pendley, R.E.

1985-01-01

For almost four decades, the United States has insisted that any increase in the number of states possessing nuclear weapons should be discouraged, claiming that nuclear proliferation would undermine international security and stability, and threaten the national security interests of the United States. This view was clearly emphasized by the Reagan administration when the President stated in 1981 that the basis of US nonproliferation policy was to ''establish the prevention of the spread of nuclear weapons as a fundamental national security and foreign policy objective.'' However, actual implementation of this policy, seeking to obviate moves toward increased regional nuclear capabilities, will call for a variety of bilateral security dealings with so-called problem countries in regions important to the United States, relationships that US governments have been largely chary of so far. It will also require discrimination and forcefulness in identifying the security interests of the United States in these key regions, and crafting specific foreign policies to further those interests

Humphrey, J.; Hartog, M.; Middleton, H.

1982-01-01

A pamphlet has been produced by the Medical Campaign Against Nuclear Weapons (MCANW) and by the Medical Association for the Prevention of War (MAPW) to bring the catastrophic effects that the use of nuclear weapons would entail to the attention of the general public, politicians and members of the medical profession. It describes the medical consequences of the effects of blast, heat and ionizing radiation from nuclear weapons, including details from the Hiroshima and Nagasaki atomic bombings. The medical consequences of a nuclear attack including consideration of the casualties, care of the injured, psychological effects and the outcome are also discussed. It is concluded that if for none other than purely medical reasons, nuclear warfare must never be allowed to happen. (UK)

Find and neutralize clandestine nuclear weapons

International Nuclear Information System (INIS)

Canavan, G.H.

1997-09-01

The objective of finding nuclear material at entry portals is to provide a secure perimeter as large as a weapon damage radius so that operations could be conducted within it relatively unencumbered. The objective of wide area search for nuclear material to provide a safe zone of similar dimensions in an area in which it is not possible to maintain a secure perimeter, to provide assurance for civilians living at an area at risk, or to provide rapid, wide area search of regions that could conceal nuclear threats to forces in the field. This rapid, wide-area, and confident detection of nuclear materials is the essential first step in developing the ability to negate terrorist nuclear assemblies or weapons. The ability to detect and negate nuclear materials are necessary to prevent the forced, massive evacuation of urban populations or the disruption of military operations in response to terrorist threats. This paper describes the limitations to current sensors used for nuclear weapon detection and discusses a novel approach to nuclear weapon detection using a combination of directional information (imaging) and gamma ray energy (color) to produce a gamma ray color camera

For 40 years, the Pugwash Conference on Science and world affairs has been making unremitting efforts to achieve it main objectives the struggle to eliminate nuclear weapons, the elimination of wars and maintenance of world peace. The end of the Cold War vigorously encouraged world efforts in arms control and disarmament. On the day of exploding her first nuclear bomb in October 1964, China declared solemnly that it would never be the first to use nuclear weapons at any time under any circumstances. China has also committed unconditionally not to use nuclear weapons or threaten to use nuclear weapons against non-nuclear weapon states and nuclear free zones. China is the sole nuclear weapon state that has made this commitment, and she has kept her word. China is in favour of comprehensive nuclear test ban in the move towards complete nuclear disarmament, taking an active part in the CTBT negotiations in Geneva and contributing to the conclusion of a fair, reasonable, verifiable treaty of universal adherence and unlimited duration within this year

Steps toward a Middle East free of nuclear weapons

International Nuclear Information System (INIS)

Leonard, J.

1991-01-01

In the aftermath of the Gulf War, all eyes are focused on the dangers of proliferation in the Middle East. President Bush, in his postwar address to Congress, called for immediate action to control the proliferation of weapons of mass destruction and the missiles used to deliver them, warning that it would be tragic if the nations of the Middle East and Persian Gulf were now, in the wake of war, to embark on a new arms race. Secretary of State James Baker has recently returned from a tour of the region, and consultations on proliferation were reportedly high on his agenda. At the same time, the fierce political antagonisms and unbridled military competitions that have long characterized the Middle East leave many skeptical as to what can realistically be done. While all states in the region - including Israel - have publicly supported the idea of establishing a nuclear-weapon-free zone (NWFZ) in the Middle East, doubt over the feasibility of the proposal runs high. Why on earth, it is asked, would Israelis give up the protection of their nuclear monopoly? What assurances from their Arab adversaries or from the US could possibly replace this ultimate deterrent?

The volume contains, in addition to an introduction into the matter, the texts of the Foreign Trade Act (FTA), the War Weapons Control Act and all relevant ordinances. Foreign trade transactions of the Federal Republic of Germany are essentially, but not exclusively, governed by the FTA. They are strongly influenced by the legislation of the European Communities which in the form of directives are immediately effective here, and in the form of guidelines oblige the German lawgiver or ordinance giver to translate them into practice, mostly by appropriate modifications of the foreign trade ordinance, the import and export lists. It is not the war weapons which are the problem, but the so-called dual-use goods, namely articles, technologies and knowledge which, as a rule, serve civil purposes, which, however, may be used also to produce weapons, in particular ABC weapons or rockets. Nowadays we are concerned about several third-world states which are obsessed by the wish to build their own atomic bomb. (orig./HSCH) [de

Oil and influence: the oil weapon examined

Energy Technology Data Exchange (ETDEWEB)

Maull, H

1975-01-01

The term ''oil weapon'' as used here signifies any manipulation of the price and/or supply of oil by exporting nations with the intention of changing the political behavior of the consumer nations. The political potential of the oil price is fairly restricted so, in effect, the supply interruptions are of prime concern. Manipulating price does, in principle, offer the possibilities of both conferring rewards and inflicting sanctions. Oil could be sold on preferential prices and terms. A precondition for using the oil weapon successfully would be the ability to cause real and serious damage to the consumer countries. Four damaging potentials for using the oil weapon could include its application by: (1) one producer against one consumer; (2) one producer against all consumers; (3) a group of producers against one consumer; and (4) by a group of producers against all consumers. It is concluded that the oil weapon will continue to be a force in the international system. (MCW)

From weapons to waste: The future of the nuclear weapons complex

International Nuclear Information System (INIS)

Wasserman Goodman, Sherri

1992-01-01

This paper examines how decision-making power has shifted within the nuclear weapons complex, from the federal government operating agency, in which power was originally vested by the Atomic Energy Act, to the states and to regulatory authorities. Additionally, when the original operating agency, the Atomic Energy Commission (AEC), was abolished in the 1970s, substantial decision-making power shifted from Washington to the field sites. This paper identifies the needs for future materials and weapons production, and recommends that restart of old plants be abandoned as no longer militarily necessary. Instead, the U. S. should take advantage of what may be a unique opportunity to 'leapfrog' to new, smaller, technologically-advanced plants that will meet the needs of the nuclear arsenal in the post-Cold War world. This paper then looks at the current state of DOE's environmental restoration/waste management program, and the technological, legal and political problems it faces in trying to accomplish its mission of cleaning up all nuclear weapons sites. This paper argues that the U. S. government no longer has the exclusive authority to make and carry out critical decisions affecting a cleanup program that will cost the U. S. over $200 billion over the next 20-40 years. Moreover, there are competing theories about the principles that should guide the cleanup program. Finally, the author examines alternative futures for the DOE'S environmental restoration/waste management program. (author)

Worldwide governmental efforts to locate and destroy chemical weapons and weapons materials: minimizing risk in transport and destruction.

Trapp, Ralf

2006-09-01

The article gives an overview on worldwide efforts to eliminate chemical weapons and facilities for their production in the context of the implementation of the 1997 Chemical Weapons Convention (CWC). It highlights the objectives of the Organisation for the Prohibition of Chemical Weapons (OPCW), the international agency set up in The Hague to implement the CWC, and provides an overview of the present status of implementation of the CWC requirements with respect to chemical weapons (CW) destruction under strict international verification. It addresses new requirements that result from an increased threat that terrorists might attempt to acquire or manufacture CW or related materials. The article provides an overview of risks associated with CW and their elimination, from storage or recovery to destruction. It differentiates between CW in stockpile and old/abandoned CW, and gives an overview on the factors and key processes that risk assessment, management, and communication need to address. This discussion is set in the overall context of the CWC that requires the completion of the destruction of all declared CW stockpiles by 2012 at the latest.

This communication addresses real-time weapon classification by analysis of asynchronous acoustic data, collected from microphones on a sensor network. The weapon classification algorithm consists of two parts: (i) feature extraction from time-series data using symbolic dynamic filtering (SDF), and (ii) pattern classification based on the extracted features using the language measure (LM) and support vector machine (SVM). The proposed algorithm has been tested on field data, generated by firing of two types of rifles. The results of analysis demonstrate high accuracy and fast execution of the pattern classification algorithm with low memory requirements. Potential applications include simultaneous shooter localization and weapon classification with soldier-wearable networked sensors. (rapid communication)

[Ludwig Wittgenstein (1889-1951) and the "wound shock"].

Gentili, Marc E

2015-01-01

Ludwig Wittgenstein was born in 1889 in Vienna. As a scholar in Cambdrige University, his philosophical achievements are still major regarding the foundations of mathematics and language. In 1939, he took a job as a porter at London Guys' Hospital then under the Blitz. Wittgenstein met Drs. Grant and Reeve who worked in a dedicated "traumatic shock" under the auspices of the Medical Research Council unit, a unit which then moved to the Royal Victoria Infirmary in Newcastle; Wittgenstein followed them as a technician and improved the preparation of fine pieces of histology fixed by paraffin. He also invented a new device to record pulse pressure and paradoxical pulse search in laboratory rats. At the end of the war, he returned to Cambridge until 1949 and died in 1951.

ON THE OFFENSE: USING CYBER WEAPONS TO INFLUENCE COGNITIVE BEHAVIOR

Directory of Open Access Journals (Sweden)

Mary Fendley

2012-12-01

Full Text Available There is an increasing recognition that cyber warfare is an important area of development for targeting and weaponeering, with far-reaching effects in national defense and economic security. The ability to conduct effective operations in cyberspace relies on a robust situational awareness of events occurring in both the physical and information domains, with an understanding of how they affect the cognitive domain of friendly, neutral, and adversary population sets. The dynamic nature of the battlefield complicates efforts to understand shifting adversary motivations and intentions. There are very few approaches, to date, that systematically evaluate the effects of the repertoire of cyber weapons on the cognitive, perceptual, and behavioral characteristics of the adversary. In this paper, we describe a software environment called Cognitive Cyber Weapon Selection Tool (CCWST that simulates a scenario involving cyber weaponry.This tool provides the capabilities to test weapons which may induce behavioral state changes in the adversaries. CCWST provides the required situational awareness to the Cyber Information Operations (IO planner to conduct intelligent weapon selection during weapon activation in order to induce the desired behavioral change in the perception of the adversary. Weapons designed to induce the cognitive state changes of deception, distraction, distrust and confusion were then tested empirically to evaluate the capabilities and expected cognitive state changes induced by these weapons. The results demonstrated that CCWST is a powerful environment within which to test and evaluate the impact of cyber weapons on influencing cognitive behavioral states during information processing.

Proposals for chemical weapons during the American Civil War.

Science.gov (United States)

Hasegawa, Guy R

2008-05-01

Proposals for chemical weapons that arose during the American Civil War are described. Most incendiary and all biological agents are excluded. The described proposals appeared primarily in periodicals or letters to government officials on both sides. The weapons were usually meant to temporarily disable enemy combatants, but some might have been lethal, and Civil War caregivers were ill-prepared to deal with the weapons' effects. Evidently, none of the proposed weapons were used. In only one instance was use against civilians mentioned. Among the agents most commonly proposed were cayenne pepper or other plant-based irritants such as black pepper, snuff, mustard, and veratria. Other suggested agents included chloroform, chlorine, hydrogen cyanide, arsenic compounds, sulfur, and acids. Proponents usually suggested that the chemicals be included in explosive artillery projectiles. Less commonly proposed vehicles of delivery included fire engines, kites, and manned balloons. Some of the proposed weapons have modern counterparts.

Whether he intended it or not, Bush has taken steps that mean the beginning of the end for nuclear weapons. His proposals significantly reduce the numbers of nuclear weapons and the burdens associated with deploying and controlling them. And although he retains many of the options for continuing and regenerating the nuclear arsenal, he has exposed the fact that there are no longer any grand justifications or doctrinal needs for nuclear weapons - and that the nuclear machine is choking on its economic, political, environmental, and human contradictions. The initiatives fundamentally altered the nuclear stance of both nations. Yet, as momentous as the changes were, they were set in motion in an almost businesslike manner. Neither leader truly framed the moves as an end to the nuclear age. But they didn't need to. The steps they have taken practically guarantee it

Chemical and biological weapons in the 'new wars'.

Science.gov (United States)

Ilchmann, Kai; Revill, James

2014-09-01

The strategic use of disease and poison in warfare has been subject to a longstanding and cross-cultural taboo that condemns the hostile exploitation of poisons and disease as the act of a pariah. In short, biological and chemical weapons are simply not fair game. The normative opprobrium is, however, not fixed, but context dependent and, as a social phenomenon, remains subject to erosion by social (or more specifically, antisocial) actors. The cross cultural understanding that fighting with poisons and disease is reprehensible, that they are taboo, is codified through a web of interconnected measures, principal amongst these are the 1925 Geneva Protocol; the Biological Weapons Convention; and the Chemical Weapons Convention. Whilst these treaties have weathered the storm of international events reasonably well, their continued health is premised on their being 'tended to' in the face of contextual changes, particularly facing changes in science and technology, as well as the changed nature and character of conflict. This article looks at the potential for normative erosion of the norm against chemical and biological weapons in the face of these contextual changes and the creeping legitimization of chemical and biological weapons.

Legality of the threat or use of nuclear weapons

Chang Yenchiang

2009-01-01

This paper examines international treaties in relation to the threat or use of nuclear weapons including the 1968 Nuclear Non-Proliferation Treaty and the 1996 Comprehensive Test Ban Treaty. It can be concluded that the effect of the aforesaid international treaties is still in doubt without explicit enforcement mechanisms and penalty for non-compliance. This paper also reviews the International Court of Justice's advisory opinion on the legality of the threat or use of nuclear weapons and comments that a clear explanation on the legality of use of nuclear weapons in 'extreme circumstances of self-defence' is required. Examples from current state practice in relation to nuclear non-proliferation efforts are also provided, with special attention to China, North Korea and Iran. This paper suggests that China as a leader of developing countries should extend its efforts on nuclear non-proliferation and conduct communication between North Korea and Iran and other nuclear weapons states to reduce or prohibit nuclear weapons.

Confirming the nature of the knot near the pulsar B1951+32

Science.gov (United States)

Zyuzin, D. A.; Shibanov, Yu A.; Pavlov, G. G.; Danilenko, A. A.

2017-12-01

The energetic and fast-moving radio and γ-ray pulsar B1951+32 is associated with the supernova remnant CTB 80. It powers a complex pulsar wind nebula detected in the radio, Hα and X-rays (Moon et al 2004 ApJ 610 L33). A puzzling optical knot was detected about 0″.5 from the pulsar in the optical and near-IR (Moon et al 2004 ApJ 610 L33; Hester 2000 Bulletin of the AAS 32 1542). It is reminiscent of the unique “inner optical knot” located 0″.6 from the Crab pulsar. Until now there has been no evidence that B1951+32 knot is indeed associated with the pulsar. We observed the pulsar field with the Gemini-North telescope in 2016 to check the association. We performed first near-IR high spatial resolution imaging in the K s band using the NIRI+Altair instrument and deep optical imaging in the gr bands using the GMOS instrument. Our observations showed that the current knot position is shifted by ≈ 0″.6 from the position measured with the HST in 1997. This is consistent with the known pulsar proper motion and is direct evidence of the pulsar-knot connection. We compared the spectral energy distribution of the knot emission with that of the Crab knot. Possible implications of the results are discussed.

Prions: the danger of biochemical weapons

Directory of Open Access Journals (Sweden)

Eric Almeida Xavier

2014-09-01

Full Text Available The knowledge of biotechnology increases the risk of using biochemical weapons for mass destruction. Prions are unprecedented infectious pathogens that cause a group of fatal neurodegenerative diseases by a novel mechanism. They are transmissible particles that are devoid of nucleic acid. Due to their singular characteristics, Prions emerge as potential danger since they can be used in the development of such weapons. Prions cause fatal infectious diseases, and to date there is no therapeutic or prophylactic approach against these diseases. Furthermore, Prions are resistant to food-preparation treatments such as high heat and can find their way from the digestive system into the nervous system; recombinant Prions are infectious either bound to soil particles or in aerosols. Therefore, lethal Prions can be developed by malicious researchers who could use it to attack political enemies since such weapons cause diseases that could be above suspicion.

Application of inertial confinement fusion to weapon technology

International Nuclear Information System (INIS)

Toepfer, A.J.; Posey, L.D.

1978-12-01

This report reviews aspects of the military applications of the inertial confinement fusion (ICF) program at Sandia Laboratories. These applications exist in the areas of: (1) weapon physics research, and (2) weapon effects simulation. In the area of weapon physics research, ICF source technology can be used to study: (1) equations-of-state at high energy densities, (2) implosion dynamics, and (3) laboratory simulation of exoatmospheric burst phenomena. In the area of weapon effects simulation, ICF technology and facilities have direct near, intermediate, and far term applications. In the near term, short pulse x-ray simulation capabilities exist for electronic component effects testing. In the intermediate term, capabilities can be developed for high energy neutron exposures and bremsstrahlung x-ray exposures of components. In the far term, system level exposures of full reentry vehicles will be possible if sufficiently high pellet gains are achieved

The tale of the shrinking weapon: seasonal changes in nutrition affect weapon size and sexual dimorphism, but not contemporary evolution.

Science.gov (United States)

Miller, C W; McDonald, G C; Moore, A J

2016-11-01

Sexually selected traits are often highly variable in size within populations due to their close link with the physical condition of individuals. Nutrition has a large impact on physical condition, and thus, any seasonal changes in nutritional quality are predicted to alter the average size of sexually selected traits as well as the degree of sexual dimorphism in populations. However, although traits affected by mate choice are well studied, we have a surprising lack of knowledge of how natural variation in nutrition affects the expression of sexually selected weapons and sexual dimorphism. Further, few studies explicitly test for differences in the heritability and mean-scaled evolvability of sexually selected traits across conditions. We studied Narnia femorata (Hemiptera: Coreidae), an insect where males use their hind legs as weapons and the femurs are enlarged, to understand the extent to which weapon expression, sexual dimorphism and evolvability change across the actual range of nutrition available in the wild. We found that insects raised on a poor diet (cactus without fruit) are nearly monomorphic, whereas those raised on a high-quality diet (cactus with ripe fruit) are distinctly sexually dimorphic via the expression of large hind leg weapons in males. Contrary to our expectations, we found little evidence of a potential for evolutionary change for any trait measured. Thus, although we show weapons are highly condition dependent, and changes in weapon expression and dimorphism could alter evolutionary dynamics, our populations are unlikely to experience further evolutionary changes under current conditions. © 2016 European Society For Evolutionary Biology.

Cooperative Security: A New Paradigm For A World Without Nuclear Weapons?

Directory of Open Access Journals (Sweden)

Marc Finaud

2013-11-01

Full Text Available If there is a loose consensus on aiming at a world free of nuclear weapons in the future, there are clear oppositions as to the timeframe as well as the means for achieving this goal. The approach to nuclear disarmament followed to date has only yielded limited success because it has been conceived in isolation from global and regional security environments and threat perceptions. A new paradigm should thus be sought in order to reconcile nuclear powers’ security doctrines with global aspirations for a safer world, and ensure that nuclear powers derive their security less from others’ insecurity but from mutually beneficial cooperative security. This should not become a pretext for preserving nuclear weapons for ever. It will on the contrary require parallel tracks addressing the initial motivations for acquiring nuclear weapons and other weapons of mass destruction (WMD, in particular in the context of regional conflicts, as well as dealing with the current issues necessarily related to nuclear disarmament (missile defence, weaponization of space, conventional imbalances and future weapon systems. Ultimately, in a globalised nuclear-weapon free world, state security will not require nuclear weapons because it will be inserted into a broader network encompass­ing all aspects of security addressed in cooperative and multilateral approaches.

1993-01-01

Speaking on the problems of preventing proliferations of nuclear weapons and nuclear disarmament the author suggests the following measures to reach these goals: signing a treaty that binds all the nuclear weapon states to the no-first-use principle as a basic policy; the United Nations should put the elimination of nuclear weapons on its agenda; having the treaty safeguarded two-pronged verification regime, one would be technological verification, the second one - so called societal verification which means that not just a group of experts but everybody would be asked to take part in ensuring that the treaty would not be violated

The paper examines the issue of nuclear-weapon States involvement in regional conflicts, and whether such a conflict in the Middle East could trigger a nuclear war between the Super-Powers. Comments on the Middle Eastern situation are given, along with a discussion of the Non-Proliferation Treaty (NPT) and the Middle East, Israel and the NPT, and the nuclear potential in Arab countries. The proposal, by Israel, of a nuclear weapon-free zone in the Middle East is outlined. (UK)

Treaty on the non-proliferation of nuclear weapons. 2005 review conference of the Treaty on the Non-Proliferation of Nuclear Weapons, 2 May 2005, United Nations, New York, USA

International Nuclear Information System (INIS)

ElBaradei, M.

2005-01-01

The core of the Treaty on the Non-Proliferation of Nuclear Weapons can be summed up in two words: 'Security' and 'Development'. While the States Party to this Treaty hold differing priorities and views, I trust that all share these two goals: development for all through advanced technology; and security for all by reducing - and ultimately eliminating - the nuclear threat. These shared goals were the foundation on which the international community, in 1970, built this landmark Treaty. They agreed to work towards a world free of nuclear weapons. They agreed, while working towards this goal, to prevent the acquisition of nuclear weapons by additional States. And they agreed to make the peaceful applications of nuclear energy available to all. Folded together, these agreements, these commitments, are mutually reinforcing. They are as valid today as when they were first made - and even more urgent. What should be all too evident is that, if we cannot work together, each acknowledging the development priorities and security concerns of the other, then the result of this Conference will be inaction. In five years, since the 2000 NPT Review Conference the world has changed. Our fears of a deadly nuclear detonation, whatever the cause, have been reawakened. These realities have heightened the awareness of vulnerabilities in the NPT regime. The Treaty has served us well for 35 years. But unless we regard it as part of a living, dynamic regime - capable of evolving to match changing realities, it will fade into irrelevance and leave us vulnerable and unprotected. The expectations from this Conference are to: re-affirm the goals established in 1970; strengthen the IAEA's verification authority; control over proliferation sensitive parts of the nuclear fuel cycle (activities that involve uranium enrichment and plutonium separation); secure and control nuclear material; show the world that our commitment to nuclear disarmament is firm; back the verification efforts by an

Full Text Available This article reviews the sociopolitical and economical situation of Catalonia during the first years of Francoism, specially in Barcelona. It shows some examples of oposition against this regime, which led to the general strike of March, 1951. First of all, it studies the position of the textile industry businessmen and the economical and social situation at the late forties. It analyze the opposition to a «single party» politics in the first local elections of November, 1948, and the high abstention. It shows that the visit of Franco to Barcelona in an atmosphere of economical crisis failed to gain support for his regime. Finally, it explains how the general strike of March, 1951, marked a turning point in the crisis and it provoked a change in the policies of the government.

Suh, Young A; Yim, Man Sung [Korea Advanced Institute of Science and Technology, Daejeon (Korea, Republic of)

2015-05-15

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

Does nuclear power lead to nuclear weapons

International Nuclear Information System (INIS)

Prawitz, J.

1977-01-01

It is pointed out that 'reactor grade' plutonium usually contains about 30 % Pu240 and is unsuitable for weapons. While it is possible to obtain an explosion, it is more difficult to initiate one and its effect, which will be considerably less than with bomb grade plutonium, is difficult to predict. The critical mass will be larger and more cooling required. The proliferation problem is then discussed and the four aspects, vertical, horizontal, sub-national and revolutionary, mentioned. In connection with nuclear power it is the second and third aspects which are of interest. In discussing the possibility of terrorist groups obtaining plutonium, a study by the Swedish Defence Research Institute is quoted as estimating that 10-20 qualified specialists and several years secret preparation would be necessary to make a nuclear weapon. Other authors, e.g. Ted Taylor, have maintained that it would be much easier, but examples of 'student designs' are primitive and unlikely to detonate. Even so, it is emphasised that safeguards and physical security are necessary. Horizontal proliferation is a more real problem and the NPT and IAEA safeguards are discussed in this connection. In conclusion the question of whether the proliferation of nuclear weapons via nuclear power can be prevented cannot be answered with a clear yes or no. Certain states may use nuclear weapon potential as a bargaining factor. However the decision to acquire nuclear weapons is political and while a nuclear power industry would be of help, it would not be decisively so. (JIW)

Why are U.S. nuclear weapon modernization efforts controversial?

Science.gov (United States)

Acton, James

2016-03-01

U.S. nuclear weapon modernization programs are focused on extending the lives of existing warheads and developing new delivery vehicles to replace ageing bombers, intercontinental ballistic missiles, and ballistic missile submarines. These efforts are contested and controversial. Some critics argue that they are largely unnecessary, financially wasteful and potentially destabilizing. Other critics posit that they do not go far enough and that nuclear weapons with new military capabilities are required. At its core, this debate centers on three strategic questions. First, what roles should nuclear weapons be assigned? Second, what military capabilities do nuclear weapons need to fulfill these roles? Third, how severe are the unintended escalation risks associated with particular systems? Proponents of scaled-down modernization efforts generally argue for reducing the role of nuclear weapons but also that, even under existing policy, new military capabilities are not required. They also tend to stress the escalation risks of new--and even some existing--capabilities. Proponents of enhanced modernization efforts tend to advocate for a more expansive role for nuclear weapons in national security strategy. They also often argue that nuclear deterrence would be enhanced by lower yield weapons and/or so called bunker busters able to destroy more deeply buried targets. The debate is further fueled by technical disagreements over many aspects of ongoing and proposed modernization efforts. Some of these disagreements--such as the need for warhead life extension programs and their necessary scope--are essentially impossible to resolve at the unclassified level. By contrast, unclassified analysis can help elucidate--though not answer--other questions, such as the potential value of bunker busters.

Nuclear weapons in the India-Pakistan context

International Nuclear Information System (INIS)

Sanjay Badri-Maharaj

2002-01-01

This thesis deals with the possible employment of nuclear weapons in the ongoing confrontation between India and Pakistan. After reviewing the nuclear capabilities of both Indian and Pakistan and assessing their possible delivery systems, this dissertation explores the emerging picture regarding the Indian and Pakistani nuclear doctrines. It is argued that, after exploring the current structure of the armed forces in both countries and after analyzing the theatres of operations, it is highly unlikely that either country seeks to employ nuclear weapons in a tactical, battlefield role. It is also argued that neither India or Pakistan is making an effort to evolve a nuclear war-fighting doctrine. Moreover, it is shown that nuclear weapons have simply led to a re-thinking of military tactics on the part of India so as to minimize the chance of a nuclear strike by limiting the aims and objectives of any Indian military action. In stark contrast, it is shown that South Asian cities present far more lucrative targets for nuclear strikes. As a result of this and the geographic and tactical limitations of South Asian battlefields, it is argued that both India and Pakistan have based their fledgling nuclear strategies around a 'city-busting' concept. The existing command and control systems in both countries are examined and found to be adequate if both countries adopt a strict 'second-strike' approach to the employment of nuclear weapons. It is further argued that nuclear weapons, while limiting the scale of any future India-Pakistan war, will not play a major role in preventing a conflict between the two countries. Rather, the basic operational parity that exists between the two countries in terms of their conventional forces is responsible for preventing the outbreak of war. The thesis also briefly explores the rationale behind the acquisition of nuclear weapons in both countries and on their basic security perceptions. The issue of confidence building measures and the

Palaeointensity Results from 1951 and 1995 Lava Flows, Fogo, Cape Verde: A Comparison between Thellier and LTD-DHT Shaw Methods

As part of an ongoing effort to link the success rate of palaeointensity experiments to specific rock magnetic properties, we present new palaeointensity results from basaltic lavas erupted in 1951 and 1995 on the island of Fogo, Cape Verde. Both Thellier and LTD-DHT Shaw palaeointensity experiments were used to estimate the historical field strength. The intensity of the field during these eruptions is constrained by data from the Mbour geomagnetic observatory (Senegal) and IGRF10. In 1951, the magnetic field intensity at Fogo was approximately 33.8 µT during the eruption of three distinct surface flows, covering approximately 14 km2. The field intensity was approximately 32.5 µT during a 1995 eruption of one large flow that extends 4 km2 across the caldera floor. Different volcanic textures were sampled from multiple sites within both the 1951 and 1995 lava flows, including glass-rich pahoehoe and aa flows, highly vesicular flows, and massive non-vesicular lava. Detailed rock magnetic measurements demonstrate that each site and texture displays distinctively different rock magnetic properties. We assess possible links between the outcome of the Thellier and LTD-DHT palaeointensity experiments and the distribution of magnetic domain states, average oxidation state, and laboratory induced alteration.

Nuclear weapons research in Sweden. The co-operation between civilian and military research, 1947 - 1972

International Nuclear Information System (INIS)

Jonter, Thomas

2002-05-01

The Swedish nuclear weapons research began as early as 1945, shortly after the first atomic bombs fell over Japan. The assignment to look into the new weapon of mass destruction went to the Swedish National Defence Research Establishment (FOA). Admittedly, the main aim of the research initiated at that time was to find out how Sweden could best protect itself against a nuclear weapon attack. However, from the outset FOA was interested in investigating the possibilities of manufacturing what was then called an atomic bomb. A co-operation between FOA and AB Atomenergi (AE), which was created in 1947 in order to be responsible for the industrial development of civilian nuclear energy, was initiated. AE made several technical investigations within this co-operation regarding choice of reactors and preconditions for a production of weapons-grade plutonium. The first purpose of this report is therefore to investigate how this co-operation emerged and what consequences it had for the project to produce basic information for the Swedish manufacture of nuclear weapons. In general terms, the finding of this report is that FOA was responsible for the overall nuclear weapons research. For this reason, FOA was in charge of the construction of the nuclear device and the studies of its effects. Additionally, AE should deliver basic information of a possible production of weapons-grade plutonium and investigate the possibilities of a production or a procurement of inspection-free heavy water (i.e. without inspections by the supplying country). AE should also build a reprocessing plant and manufacture fuel elements to be used in the reactors for a production of weapons-grade plutonium. Furthermore, it is important to emphasise that both FOA and AE conducted plutonium research. The reason why FOA conducted this research was that the plutonium had to be in metallic form in order to be used in a nuclear weapons device. Therefore, FOA carried out research with the purpose of producing

We will present the setup of a 50 kW Laser Weapon Demonstrator (LWD) and results achieved with this system. The LWD is a ground based Air Defence system consisting of a Skyguard sensor unit for target acquisition and two laser equipped weapon turrets. The weapon turrets used are standard air defence turrets of Rheinmetall Air Defence which were equipped with several 10 kW Laser Weapon Modules (LWM). Each LWM consists of one 10 kW fiber laser and a beam forming unit (BFU). Commercial of the shelf fiber laser were modified for our defence applications. The BFU providing diffraction limited beam focusing, target imaging and fine tracking of the target was developed. The LWD was tested in a firing campaign at Rheinmetall test ground in Switzerland. All laser beams of both weapon turrets were superimposed on stationary and dynamic targets. Test results of the LWD for the scenarios Air Defence and C-RAMM (counter rockets, artillery, mortar and missiles) will be presented. An outlook for the next development stage towards a 100 kW class laser weapon on RWM will be given.

Burning weapons-grade plutonium in reactors

International Nuclear Information System (INIS)

Newman, D.F.

1993-06-01

As a result of massive reductions in deployed nuclear warheads, and their subsequent dismantlement, large quantities of surplus weapons- grade plutonium will be stored until its ultimate disposition is achieved in both the US and Russia. Ultimate disposition has the following minimum requirements: (1) preclude return of plutonium to the US and Russian stockpiles, (2) prevent environmental damage by precluding release of plutonium contamination, and (3) prevent proliferation by precluding plutonium diversion to sub-national groups or nonweapons states. The most efficient and effective way to dispose of surplus weapons-grade plutonium is to fabricate it into fuel and use it for generation of electrical energy in commercial nuclear power plants. Weapons-grade plutonium can be used as fuel in existing commercial nuclear power plants, such as those in the US and Russia. This recovers energy and economic value from weapons-grade plutonium, which otherwise represents a large cost liability to maintain in safeguarded and secure storage. The plutonium remaining in spent MOX fuel is reactor-grade, essentially the same as that being discharged in spent UO 2 fuels. MOX fuels are well developed and are currently used in a number of LWRs in Europe. Plutonium-bearing fuels without uranium (non-fertile fuels) would require some development. However, such non-fertile fuels are attractive from a nonproliferation perspective because they avoid the insitu production of additional plutonium and enhance the annihilation of the plutonium inventory on a once-through fuel cycle

Males that drop a sexually selected weapon grow larger testes.

Costly sexually selected weapons are predicted to trade off with postcopulatory traits, such as testes. Although weapons can be important for achieving access to females, individuals of some species can permanently drop (i.e. autotomize) their weapons, without regeneration, to escape danger. We capitalized on this natural behavior to experimentally address whether the loss of a sexually selected weapon leads to increased testes investment in the leaf-footed cactus bug, Narnia femorata Stål (Hemiptera: Coreidae). In a second experiment, we measured offspring production for males that lost a weapon during development. As predicted, males that dropped a hind limb during development grew significantly larger testes than the control treatments. Hind-limb autotomy did not result in the enlargement of other nearby traits. Our results are the first to experimentally demonstrate that males compensate for natural weapon loss by investing more in testes. In a second experiment we found that females paired with males that lost a hind limb had 40% lower egg hatching success than females paired with intact males, perhaps because of lower mating receptivity to males with a lost limb. Importantly, in those cases where viable offspring were produced, males missing a hind limb produced 42% more offspring than males with intact limbs. These results suggest that the loss of a hind-limb weapon can, in some cases, lead to greater fertilization success. © 2017 The Author(s). Evolution © 2017 The Society for the Study of Evolution.

Rappert, Brian

2003-10-01

Since 11 September 2001 and the anthrax attacks that followed in the US, public and policy concerns about the security threats posed by biological weapons have increased significantly. With this has come an expansion of those activities in civil society deemed as potential sites for applying security controls. This paper examines the assumptions and implications of national and international efforts in one such area: how a balance or integration can take place between security and openness in civilian biomedical research through devising professional codes of conduct for scientists. Future attempts to establish such codes must find a way of reconciling or at least addressing dilemmatic and tension-ridden issues about the appropriateness of research; a topic that raises fundamental questions about the position of science within society.

International audience; The 1956 Dartmouth conference is often considered as the cradle of artificial intelligence. There is a controversy on its origin. Some historians of computing believe that Turing or Zuse were the fathers of machine intelligence. However, the first working chess-playing automaton was developed by Torres Quevedo by 1912. Moreover, there was a large and important (but forgotten) European conference on computing and human thinking in Paris in 1951.

The risk of nuclear weapons proliferation

International Nuclear Information System (INIS)

Oelgaard, P.L.

1994-01-01

During the later years the risks of nuclear proliferation have again become a major topic of interest. This is primarily due to the acute problems caused by Iraq, North Korea, and the 3 new states of the former USSR, Ukraine, Kazakhstan and Belarus. Analysis shows that security problems and prestige are the two most important motives, when the risks of proliferation are considered. But motives are not enough. To produce nuclear weapons a number of technological requirements must also be fulfilled. The country must be able to produce almost pure fissile material, i.e. 235 U or 239 Pu. It must also be able to solve a number of metallurgical, explosive, ignition, physics and other problems. These are in particular non-trivial, if a implosion weapon is to be designed. A review is made of the nuclear facilities in a number of the countries which have been suggested as possible future nuclear weapons countries. In particular facilities which can produce almost pure fissile materials, 235 U and 239 Pu, are considered. The possibility of nuclear terrorists have often been discussed in the media. However, it seems very unlikely that even a major terrorist or mafia organization will be able to solve all the weapons design problems, even if they could steal the fissile material. It is finally discussed what can be done to reduce the risk of further nuclear proliferation. Political pressure can be brought to bear on countries outside the NPT to join it, but it can be counter-productive, and sometimes the countries that are able to exert such pressure, are not willing to do so for other political reasons. The problem of countries which are party to the NPT, but which are believed to acquire nuclear weapons capability in violation of the treaty, can be countered by unannounced inspections of non-declared facilities. However, such inspections can only be meaningfully performed if the necessary intelligence is available. (EG)

The proliferation of massive destruction weapons and ballistic missiles

Schmitt, M.

1996-01-01

The author studies the actual situation of nuclear deterrence policies, the possibilities of use chemical weapons as massive destructions weapons for non nuclear governments. The situation of non proliferation of nuclear weapons took a new interest with the disintegration of the communism block, but it seems that only few nuclear matter disappeared towards proliferating countries. The denuclearization of Bielorussia, Ukraine and Kazakhstan makes progress with the START I treaty; China has signed the Non proliferation treaty in 1992, it conducts an export policy in matter of equipment and know-how, towards Iran, Pakistan, North Korea, Saudi Arabia and Syria. In a future of ten years, countries such, Iran, North Korea could catch up with Israel, India and Pakistan among non declared nuclear countries. For chemical weapon, Libya, Iran and Syria could catch up with Iraq. (N.C.)

The Spear: An Effective Weapon Since Antiquity

Directory of Open Access Journals (Sweden)

Robert E. Dohrenwend

2012-07-01

Full Text Available The spear is perhaps man’s oldest weapon, and may even be his oldest tool. Over the hundreds of thousands of years of the weapon’s existence, it evolved from a pointed stick into an efficient hunting missile, and then became the most effective hand-held bladed weapon humans ever devised. The spear and its use is the only martial art originally devised for use against species other than our own, and more than any other weapon, the spear emphasizes the relationship between hunting and warfare. Virtually without exception, the spear is present wherever there are humans. The spear may claim to be the senior martial art, and the weapon is still in use today. Early techniques are preserved by the small number of Japanese sojutsu schools, and modern Chinese martial artists have developed elegant and impressive gymnastic routines for the spear. The javelin throw is a modern Olympic track and field event, and there are people who have resurrected the Aztec atlatl for sporting competition. Today, the spear is still used in Europe for hunting wild boar, and the continued issue of the obsolete bayonet to modern soldiers testifies to a deep, almost instinctive respect still possessed by the military for the spear.

The Wall as a Spatial Work: the Reliefs of Jorge Oteiza in Architecture (1951-58

Directory of Open Access Journals (Sweden)

Emma López Bahut

2014-03-01

Full Text Available This paper analyses the mural projects of Basque sculptor Jorge Oteiza on façades and internal walls between the years 1951-58. At first, he dealt with walls as ground planes on which to execute his sculptures, finally viewing them as an empty plane with spatial possibilities, defined by the minimum forms and the action of natural light. Based on original, previously unpublished material, we explore the evolution of this work with the aim of establishing to what extent this process was marked by the architecture on which his work was executed, by the architects with whom he collaborated, or the stage of his sculptural experimentation with which they are associated. We show that apart from the presence of an architect, there is a correlation between the way in which the reliefs were applied to the wall and the work carried out on the space where the project was created: the larger the spatial work on the wall, the greater the relationship with the space within which it was inserted, at every scale, from the interior of the architecture to the urban space.

Non-proliferation of nuclear weapons

During the turbulant transitional events in world politics in the nineties, the control of nuclear weapons plays a major role. While the superpowers are reducing their nuclear arsenal, the danger of nuclear anarchy in the world remains virulent. The NPT of 1968 is up for review soon. The falling apart of the former communist sphere of power, and the regions of conflict in the Third World present new risks for the proliferation of nuclear arms. For unified Germany, which explicitly renounced nuclear weapons, this situation presents difficult questions concerning national safety policies and international responsibility. This volume presents contributions which take a new look at topical and long-term problems of nuclear NP politics. The authors evaluate the conditions under which the NP regime came into being, and assess short- and long-term possibilities and risks. The following papers are included: 1.) Basic controversies during the negotiations concerning the Treaty on non-proliferation of nuclear weapons (Ungerer); 2.) Prologation of the NPT 1995 and appropriate problems concerning safety and control (Haefele/Lauppe); 3.) Consequences of the Iraq case for NP policy (Ficher); 4.) Problems of nuclear technology control (Mueller); 5.) Framework conditions of a nuclear world system (Haeckel). (orig./HP) [de

Hitler's bomb: the secret story of Germans' attempts to get the nuclear weapon

International Nuclear Information System (INIS)

Karlsch, Rainer

2007-01-01

In this historical book, the author claims to have evidence concerning the development and testing of a possible 'nuclear weapon' by Nazi Germany in 1945. The 'weapon' in question is not alleged to be a standard nuclear weapon powered by nuclear fission, but something closer to either a radiological weapon (a so-called 'dirty bomb') or a hybrid-nuclear fusion weapon. Its new evidence is concerned primarily with the parts of the German nuclear energy project (an attempted clandestine scientific effort led by Germany to develop and produce atomic weapons during World War II) under Kurt Diebner, a German nuclear physicist who directed and administrated the project

Biological surveys on the Savannah River in the vicinity of the Savannah River Plant (1951-1976)

Matthews, R. A.

1982-04-01

In 1951, the Academy of Natural Sciences of Philadelphia was contracted by the Savannah River Plant to initiate a long-term monitoring program in the Savannah River. The purpose of this program was to determine the effect of the Savannah River Plant on the Savannah River aquatic ecosystem. The data from this monitoring program have been computerized by the Savannah River Laboratory, and are summarized in this report. During the period from 1951-1976, 16 major surveys were conducted by the Academy in the Savannah River. Water chemistry analyses were made, and all major biological communities were sampled qualitatively during the spring and fall of each survey year. In addition, quantitative diatom data have been collected quarterly since 1953. Major changes in the Savannah River basin, in the Savannah River Plant's activities, and in the Academy sampling patterns are discussed to provide a historical overview of the biomonitoring program. Appendices include a complete taxonomic listing of species collected from the Savannah River, and summaries of the entire biological and physicochemical data base.

The repeated use of prohibited chemical weapons in the Syrian conflict poses serious health, humanitarian, and security threats to civilians, healthcare personnel, and first responders. Moreover, the use of chemical weapons constitutes a clear and egregious violation of international law-likely amounting to a war crime-for which continued impunity is setting a dangerous precedent in relation to current and future conflicts. This debate article calls upon concerned states, organizations, and individuals to respond urgently and unequivocally to this serious breach of international legal and humanitarian norms. Based on health, humanitarian, and legal findings, this article calls for concrete action to: 1) reduce the risk of chemical weapons being used in current and future conflicts; 2) review and support the preparedness equipment and antidote supplies of first responders, humanitarian organizations, and military forces operating in Syria; 3) support international mechanisms for monitoring and enforcing the prohibition on chemical weapons, including through criminal accountability; 4) support civilian victims of chemical weapons attacks, including refugees; and 5) re-commit to the complete elimination of chemical weapons in compliance with the Chemical Weapons Convention (1993), a comprehensive treaty that bans chemical weapons and requires their complete destruction. All involved states and organizations should take urgent steps to ensure the protection of the most vulnerable victims of conflict, including victims of chemical weapons attacks in Syria, and to reinforce international law in the face of such serious violations.

This report presents preliminary considerations for recovering and converting weapon plutonium from various US weapon forms into feed material for fabrication of reactor fuel elements. An ongoing DOE study addresses the disposition of excess weapon plutonium through its use as fuel for nuclear power reactors and subsequent disposal as spent fuel. The spent fuel would have characteristics similar to those of commercial power spent fuel and could be similarly disposed of in a geologic repository

We investigated the prevalence of juvenile weapon carrying and psychosocial and personality-related risk factors for carrying different types of weapons in a nationally representative, population-based sample of Finnish adolescents. Specifically, we aimed to investigate psychopathic-like personality features as a risk factor for weapon carrying. The participants were 15-16-year-old adolescents from the Finnish self-report delinquency study (n = 4855). Four different groups were formed based on self-reported weapon carrying: no weapon carrying, carrying knife, gun or other weapon. The associations between psychosocial factors, psychopathic-like features and weapon carrying were examined with multinomial logistic regression analysis. 9% of the participants had carried a weapon in the past 12 months. Adolescents with a history of delinquency, victimization and antisocial friends were more likely to carry weapons in general; however, delinquency and victimization were most strongly related to gun carrying, while perceived peer delinquency (antisocial friends) was most strongly related to carrying a knife. Better academic performance was associated with a reduced likelihood of carrying a gun and knife, while feeling secure correlated with a reduced likelihood of gun carrying only. Psychopathic-like features were related to a higher likelihood of weapon carrying, even after adjusting for other risk factors. The findings of the study suggest that adolescents carrying a weapon have a large cluster of problems in their lives, which may vary based on the type of weapon carried. Furthermore, psychopathic-like features strongly relate to a higher risk of carrying a weapon.

Precipitation and temperature trends over central Italy (Abruzzo Region): 1951-2012

Science.gov (United States)

Scorzini, Anna Rita; Leopardi, Maurizio

2018-02-01

This study analyses spatial and temporal trends of precipitation and temperatures over Abruzzo Region (central Italy), using historical climatic data from a dense observation network. The results show a general, although not significant, negative trend in the regionally averaged annual precipitation (- 1.8% of the yearly mean rainfall per decade). This reduction is particularly evident in winter, especially at mountain stations (average - 3% change/decade). Despite this general decreasing trend, a partial rainfall recovery is observed after the 1980s. Furthermore, the majority of meteorological stations register a significant warming over the last 60 years, (mean annual temperature increase of + 0.15 °C/decade), which reflects a rise in both minimum and maximum temperatures, with the latter generally increasing at a faster rate. Spring and summer are the seasons which contribute most to the general temperature increase, in particular at high elevation sites, which exhibit a more pronounced warming (+ 0.24 °C/decade). However, this tendency has not been uniform over 1951-2012, but it has been characterised by a cooling phenomenon in the first 30 years (1951-1981), followed by an even stronger warming during the last three decades (1982-2012). Finally, correlations between the climatic variables and the dominant teleconnection patterns in the Mediterranean basin are analysed to identify the potential influence of large-scale atmospheric dynamics on observed trends in Abruzzo. The results highlight the dominant role of the East-Atlantic pattern on seasonal temperatures, while more spatially heterogeneous associations, depending on the complex topography of the region, are identified between winter precipitation and the North Atlantic Oscillation, East-Atlantic and East-Atlantic/Western Russian patterns.

Full Text Available Objectives: analysis of the evolution of colorectal cancer in Spain during the period 1951-2007 and its relationship with diet. Material and methods: calculation of incidence rates, standardized mortality and years of potential life lost (world population andper capita consumption of different foods. Results: red and processed meats, poultry, fish and fruits intake has increased and consumption of vegetables, cereals and legumes has decreased. The incidence of colorectal cancer has steadily increased in both genders, more markedly among men, and across all age groups, in contrast to what has been observed in other countries. Mortality increased during the period 1951-2000, but from that time until 2007 these rates have kept steady in men and fallen in women. The years of potential life lost (YPLL shows a similar distribution to mortality. The correlation coefficients have values close to one for consumption of red meat, poultry, fish, vegetables and fruits and strongly negative values for the consumption of cereals and vegetables with the incidence and mortality in both genders, and the YPLL, but only among men, with weaker correlations for women. Conclusions: in colorectal cancer, a minimal time span of ten-fifteen years is necessary for changes in exposure to risk factors to be able to modify the incidence of this tumour. Therefore, Spanish State and Regional Governments should implement legislative and educational measures in the field of Health Promotion regarding the diet urgently.Objetivos: análisis de la evolución del cáncer colorrectal en España durante el periodo 1951-2007 y su relación con la dieta.

2009-01-01

The UN member states are continuing to take measures to inter alia establish and effectively implement controls to prevent the proliferation of nuclear, biological and chemical weapons and their means of delivery in accordance with United Nations Security Council Resolution 1540 (2004). The resolution also encourages enhanced international cooperation on such efforts, including by working through the 1540 Committee. Most analyses on the implementation of the resolution have focused on nuclear issues. This presentation provides an overview of select practical activities in the chemical and biological weapon-related areas, including chemical product classification and identification, biosafety and biosecurity practices and criminal prosecutions for unauthorised chemical transfers.(author)

Nuclear weapons research in Sweden. The co-operation between civilian and military research, 1947 - 1972

Energy Technology Data Exchange (ETDEWEB)

Jonter, Thomas [Uppsala Univ. (Sweden). Dept. of History

2002-05-01

The Swedish nuclear weapons research began as early as 1945, shortly after the first atomic bombs fell over Japan. The assignment to look into the new weapon of mass destruction went to the Swedish National Defence Research Establishment (FOA). Admittedly, the main aim of the research initiated at that time was to find out how Sweden could best protect itself against a nuclear weapon attack. However, from the outset FOA was interested in investigating the possibilities of manufacturing what was then called an atomic bomb. A co-operation between FOA and AB Atomenergi (AE), which was created in 1947 in order to be responsible for the industrial development of civilian nuclear energy, was initiated. AE made several technical investigations within this co-operation regarding choice of reactors and preconditions for a production of weapons-grade plutonium. The first purpose of this report is therefore to investigate how this co-operation emerged and what consequences it had for the project to produce basic information for the Swedish manufacture of nuclear weapons. In general terms, the finding of this report is that FOA was responsible for the overall nuclear weapons research. For this reason, FOA was in charge of the construction of the nuclear device and the studies of its effects. Additionally, AE should deliver basic information of a possible production of weapons-grade plutonium and investigate the possibilities of a production or a procurement of inspection-free heavy water (i.e. without inspections by the supplying country). AE should also build a reprocessing plant and manufacture fuel elements to be used in the reactors for a production of weapons-grade plutonium. Furthermore, it is important to emphasise that both FOA and AE conducted plutonium research. The reason why FOA conducted this research was that the plutonium had to be in metallic form in order to be used in a nuclear weapons device. Therefore, FOA carried out research with the purpose of producing

Controlling weapons of mass destruction through the rule of law

Energy Technology Data Exchange (ETDEWEB)

Tanzman, E.A.

1995-08-08

Many who speak of the end of the Cold War emphasize the improvement in international relations when they speak of the momentous consequences of this event. According to this image, the half century since Trinity has been a period of sparse international communication during which the Eastern and Western blocs hibernated in their isolated dens of security alliances. The emphasis in the phrase ``Cold War`` was on the word ``cold,`` and relations with the former Communist regimes are now ``warm`` by comparison. It is equally valid to consider what has happened to the word ``was` in this highly descriptive phrase. While meaningful international dialogue was in a state of relative lethargy during much of the last fifty years, the military establishments of the Great Powers were actively engaged in using as much force as possible in their efforts to control world affairs, short of triggering a nuclear holocaust. Out of these military postures a tense peace ironically emerged, but the terms by which decisions were made about controlling weapons of mass destruction (i.e., nuclear, chemical, and biological weapons) were the terms of war. The thesis of this paper is that the end of the Cold War marks a shift away from reliance on military might toward an international commitment to controlling weapons,of mass destruction through the ``rule of law.`` Rawls wrote that ``legal system is a coercive order of public rules addressed to rational persons for the purpose of regulating their conduct and providing the framework for social cooperation. The regular and impartial administration of public rules, becomes the rule of law when applied to the legal system.`` Inparticular, Rawls identifies as part of this system of public rules those laws that aim to prevent free riders on the economic system and those that aim to correct such externalities as environmental pollution.``

A Poor Man's Nuclear Deterrent: Assessing the Value of Radiological Weapons for State Actors

Science.gov (United States)

Donohue, Nathan

The threat of weapons of mass destruction is an issue which remains at the forefront on national security. Nuclear, chemical, and biological weapons are all considered very dangerous by both state and non-state actors. Radiological weapons exist in that same category yet are not held in the same regard; the reason that is given is that these types of weapons are not the weapons of mass destruction that the other three are. Instead, radiological weapons are better considered weapons of mass disruption. Accordingly, in the academic and policy literature there has been very little perceived value associated with such weapons for use by state actors. However the historical focus on the military efficacy of radiological weapons has obscured the obvious truth that they may pose significant value for state actors. What this research shows is that the explosion of a radiological weapon could disrupt a target area in ways which could cripple the economy of an adversary state and promote widespread fear concerning exposure to radiation. Any such attack would not only necessitate large scale evacuation, but cleanup, decontamination, demolition, territory exclusion, and relocation. Moreover, the effects of such an attack would be unlikely to remain an isolated event as evacuated and displaced citizens spread across the nation carrying both fear and residual radiation. All of these factors would only be compounded by a state actor's ability to not only develop such weapons, but to manufacture them in such a composition that contemporary examples of such weapons grossly underestimate their impact. Accordingly, radiological weapons could hold great value for any state actor wishing to pursue their development and to threaten their use. Moreover, "while RDDs may not be well suited as "military weapons" in the classic sense, the use of RDDs could be powerfully coercive."1 In that sense, state actors could even acquire radiological weapons for their deterrent value. 1James L.

The organization for the prohibition of chemical weapons and the IAEA: A comparative overview

International Nuclear Information System (INIS)

Dorn, A.W.; Rolya, A.

1993-01-01

The long-awaited Chemical Weapons Convention (CWC) - which was endorsed in New York by the United Nations General Assembly on 30 November 1992 - was opened for signature on 13 January 1993. To oversee its implementation, a new international organization, the Organization for the Prohibition of Chemical Weapons (OPCW), will be established when the treaty enters into force, which could be as early as January 1995. The IAEA - as the only existing organization with a mandate for implementing an international verification system - is an important model for the structure and functioning of the OPCW. Many provisions in the CWC benefit from the lessons learned through the implementation of the IAEA's safeguards system in such matters as rights of access for inspectors, the designation of inspectors, and procedural arrangements. Overall, the structure of the IAEA and that foreseen for the OPCE are quite similar. There are, nonetheless, several structural differences. Most notably, the IAEA is charged with a dual mission, that of promoting the contribution of nuclear energy to social and economic development and of seeking to ensure that nuclear materials and facilities which have been placed under safeguards are not diverted from peaceful uses. The OPCW is responsible for achieving a complete ban on chemical weapons and is not responsible, at least as currently envisaged, for the promotion of peaceful uses of chemistry and chemical sciences

Experimental manipulation reveals a trade-off between weapons and testes.

Theory predicts a trade-off between sexually selected weapons used to secure mates and post-copulatory traits used to maximize fertilization success. However, individuals that have a greater capacity to acquire resources from the environment may invest more in both pre- and post-copulatory traits, and trade-offs may not be readily apparent. Here, we manipulate the phenotype of developing individuals to examine allocation trade-offs between weapons and testes in Mictis profana (Hemiptera: Coreidae), a species where the hind legs are sexually selected weapons used in contests over access to females. We experimentally prevented males from developing weapons by inducing them to autotomize their hind legs before the final moult to adulthood. We compared trait expression in this group to males where autotomy was induced in the mid-legs, which are presumably not under sexual selection to the same extent. We found males without weapons invested proportionally more in testes mass than those with their mid-legs removed. Males that developed to adulthood without weapons did not differ from the mid-leg removal group in other traits potentially under precopulatory sexual selection, other post-copulatory traits or naturally selected traits. In addition, a sample of adult males from the same population in the wild revealed a positive correlation between investment in testes and weapons. Our study presents a critical contribution to a growing body of literature suggesting the allocation of resources to pre- and post-copulatory sexual traits is influenced by a resource allocation trade-off and that this trade-off may only be revealed with experimental manipulation. © 2017 European Society For Evolutionary Biology.

The abolition of nuclear weapons: realistic or not? For physicians, a world without nuclear weapons is possible and above all necessary. To abolish, did you say abolish? Is the elimination of the nuclear weapon realistic?

International Nuclear Information System (INIS)

Behar, Abraham; Gere, Francois; Lalanne, Dominique

2010-06-01

In a first article, a physician explains that eliminating nuclear weapons would be a way to get rid of the temptation for some persons to use this arm of massive destruction, and that it would be better for mankind to live without this threat. The author of the second article discusses the effect abolition could have, and, with a reference to President Obama's position about zero nuclear weapons, outlines that it could be at the benefit of peaceful uses of nuclear energy. He also discusses the perspectives of this 'global zero logics' with a new approach to arms control, and comments the relationships between abolition and non proliferation. He finally discusses the reserved attitude of France on these issues. In the next contribution, a nuclear physicist wanders whether the elimination of nuclear weapons is realistic: whereas it has always been a political objective, nuclear states refused to commit themselves in this direction in 2010 and keep on developing military-oriented tools to design new weapons

The opportunity to limit and reduce inventories of fissionable weapon materials

International Nuclear Information System (INIS)

Hebel, L.C.

1991-01-01

As the United States and the Soviet government agree on major reductions in nuclear weapon delivery systems, they need to address the disposal of the nuclear warheads and bombs for those systems. Such measures could be strongly reinforced if the two nations also institute restraints and reductions in the total amount of fissionable materials available for weapons. Many metric tonnes of such materials would be made surplus by the reductions in strategic nuclear weapons due to the Strategic Arms Reduction Treaty (START-I). Equally large reductions in short-range (theater) nuclear weapons are expected in the wake of the recent Treaty on Conventional Forces in Europe (CFE)

A Conceptual Model to Identify Intent to Use Chemical-Biological Weapons

Directory of Open Access Journals (Sweden)

Mary Zalesny

2017-10-01

Full Text Available This paper describes a conceptual model to identify and interrelate indicators of intent of non-state actors to use chemical or biological weapons. The model expands on earlier efforts to understand intent to use weapons of mass destruction by building upon well-researched theories of intent and behavior and focusing on a sub-set of weapons of mass destruction (WMD to account for the distinct challenges of employing different types of WMD in violent acts. The conceptual model is presented as a first, critical step in developing a computational model for assessing the potential for groups to use chemical or biological weapons.

Eight countries are considered to be capable of producing nuclear weapons and highly suspect in their intentions to actually produce them. These are Argentina, Brazil, India, Pakistan, Israel, South Africa, the Republic of Korea and Taiwan. The policies of these suspect Non-nuclear-weapon States (NNWS) are considered in this paper. The first part assesses the non-proliferation (or proliferation) policies of the eight suspect NNWS, the second part evaluates their differences in approach from the policies urged upon them by the nuclear-weapon states (NWS) and the third and final part attempts to understand the future evolution of NNWS policies in the nuclear military field.

Sweden and the bomb. The Swedish plans to acquire nuclear weapons, 1945 - 1972

Jonter, T [Uppsala Univ. (Sweden). Dept. of History

2001-09-01

This study analyses the Swedish nuclear weapons research since 1945 carried out by the Swedish National Defence Research Establishment (FOA). The most important aspect of this research was dealing with protection in broad terms against nuclear weapons attacks. However, another aspect was also important from early on - to conduct research aiming at a possible production of nuclear weapons. FOA performed an extended research up to 1968, when the Swedish government signed the Non-Proliferation Treaty (NPT), which meant the end of these production plans. Up to this date, five main investigations about the technical conditions were made, 1948, 1953, 1955, 1957 and 1965, which all together expanded the Swedish know-how to produce a bomb. The Swedish plans to procure nuclear weapons were not an issue in the debate until the mid-50's. The reason for this was simple, prior to 1954 the plans were secretly held within a small group of involved politicians, military and researchers. The change of this procedure did take place when the Swedish Supreme Commander in a public defence report in 1954 favoured a Swedish Nuclear weapons option. In 1958 FOA had reached a technical level that allowed the parliament to make a decision. Two programs were proposed - the L-programme (the Loading Programme), to be used if the parliament would say yes to a production of nuclear weapons, and the S-programme (the Protection Programme), if the parliament would say no. The debate on the issue had now created problems for the Social Democratic Government. The prime minister, Tage Erlander, who had earlier defended a procurement of nuclear weapons, was now forced to reach a compromise. The compromise was presented to the parliament in a creative manner that meant that only the S-programme would be allowed. The government argued that the technical level did allow a 'freedom of action' up to at least the beginning of the 60's when Sweden was mature to make a decision on the issue

The change of this procedure did take place when the Swedish Supreme Commander in a public defence report in 1954 favoured a Swedish Nuclear weapons option. In 1958 FOA had reached a technical level that allowed the parliament to make a decision. Two programs were proposed - the L-programme (the Loading Programme), to be used if the parliament would say yes to a production of nuclear weapons, and the S-programme (the Protection Programme), if the parliament would say no. The debate on the issue had now created problems for the Social Democratic Government. The prime minister, Tage Erlander, who had earlier defended a procurement of nuclear weapons, was now forced to reach a compromise. The compromise was presented to the parliament in a creative manner that meant that only the S-programme would be allowed. The government argued that the technical level did allow a 'freedom of action' up to at least the beginning of the 60's when Sweden was mature to make a decision on the issue. During this period

The paper addresses some major implications of microelectromechanical systems (MEMS) engineering and nanotechnology for the improvement of existing types of nuclear weapons, and the development of more robust versions of these weapons, as well as for the development of fourth generations nuclear weapons in which nanotechnology will play an essential role.

One in a Million Given the Accident: Assuring Nuclear Weapon Safety

Energy Technology Data Exchange (ETDEWEB)

Weaver, Jason [Sandia National Laboratories (SNL-NM), Albuquerque, NM (United States)

2015-08-25

Since the introduction of nuclear weapons, there has not been a single instance of accidental or unauthorized nuclear detonation, but there have been numerous accidents and “close calls.” As the understanding of these environments has increased, the need for a robust nuclear weapon safety philosophy has grown. This paper describes some of the methods used by the Nuclear Weapon Complex today to assure nuclear weapon safety, including testing, modeling, analysis, and design features. Lastly, it also reviews safety’s continued role in the future and examines how nuclear safety’s present maturity can play a role in strengthening security and other areas and how increased coordination can improve safety and reduce long-term cost.

After fifty years of the nuclear age: Non-proliferation of nuclear weapons or elimination of them?

International Nuclear Information System (INIS)

Sugie, Ei-Ichi

Ever since the first test of the atomic bomb and the bombing of Hiroshima and Nagasaki in 1945, mankind lived with nuclear weapons. Nuclear weapons were inevitably connected with the Cold War, with its end new opportunity has come concerning prohibition of the use of nuclear weapons. Steps are to be undertaken in order to eliminate the nuclear weapons. First, would be the prohibition of the use or the threat of use of nuclear weapons. By excluding the possibility of the use of nuclear weapons, the world could be closer to nuclear disarmament than ever. The prohibition of the use of some type of weapons could be a breakthrough towards the elimination of such weapons. While the negotiations to eliminate nuclear weapons would be difficult, as were those to ban chemical weapons, a ban on the use of nuclear weapons would eventually lead to their elimination. During the Cold War, the imminent goal of disarmament was to stop the nuclear arms race between the two superpowers. But in the post-Cold War era an opportunity has developed for further steps towards nuclear disarmament, the elimination of nuclear weapons

During Word war II, a lot of chemical weapons were left by Japanese on our land. It is very difficult to explore because its complicated states underground. There is no document about the details of this. Few of the research work have been done. In order to destroy completely abandoned chemical weapons by Japanese, the paper has given a serious study on the means to explore the chemical weapons for the purpose to protect our environment and benefit our people. After plenty of research and test, we get good results. (authors)

From Russian weapons grade plutonium to MOX fuel

International Nuclear Information System (INIS)

Braehler, G.; Kudriavtsev, E.G.; Seyve, C.

1997-01-01

The April 1996, G7 Moscow Summit on nuclear matters provided a political framework for one of the most current significant challenges: ensuring a consistent answer to the weapons grade fissile material disposition issue resulting from the disarmament effort engaged by both the USA and Russia. International technical assessments have showed that the transformation of Weapons grade Plutonium in MOX fuel is a very efficient, safe, non proliferant and economically effective solution. In this regard, COGEMA and SIEMENS, have set up a consistent technical program properly addressing incineration of weapons grade plutonium in MOX fuels. The leading point of this program would be the construction of a Weapons grade Plutonium dedicated MOX fabrication plant in Russia. Such a plant would be based on the COGEMA-SIEMENS industrial capabilities and experience. This facility would be operated by MINATOM which is the partner for COGEMA-SIEMENS. MINATOM is in charge of coordination of the activity of the Russian research and construction institutes. The project take in account international standards for non-proliferation, safety and waste management. France and Germany officials reasserted this position during their last bilateral summits held in Fribourg in February and in Dijon in June 1996. MINATOM and the whole Russian nuclear community have already expressed their interest to cooperate with COGEMA-SIEMENS in the MOX field. This follows governmental-level agreements signed in 1992 by French, German and Russian officials. For years, Russia has been dealing with research and development on MOX fabrication and utilization. So, the COGEMA-SIEMENS MOX proposal gives a realistic answer to the management of weapons grade plutonium with regard to the technical, industrial, cost and schedule factors. (author)

Joseph A. Burton Forum Award: Some Nuclear Weapons Dilemmas

Science.gov (United States)

May, Michael

2014-03-01

Nuclear weapons pose a combination of political and ethical dilemmas the solution to which has not been found. On one hand, in the view of both US government leaders and US allies, nuclear deterrence continues to play an essential part in the US role as the ultimate source of military strength for the alliances among the major democratic countries. It also continues to be in demand by countries that believe themselves to be isolated and threatened. On the other hand, nuclear weapons, besides being effective deterrents, can cause unprecedented loss of life and risk the demise of civilizations. No ban or technical precaution could prevent the rebuilding of nuclear weapons in a crisis. No diplomatic arrangement to date has erased the threat of invasion and war in the world. Only the abandonment of war and the threat of war as instruments of policy can make nuclear weapons obsolete. The slow, halting, risky road to that end remains the only hope for a world in which lasting solutions to the nuclear dilemmas are possible.

Internationalization to prevent the spread of nuclear weapons

International Nuclear Information System (INIS)

1980-01-01

The recent International Nuclear Fuel Cycle Evaluation (INFCE) has concluded that, in a world in which an increasing number of countries are using nuclear energy for peaceful purposes, no technical ways exist to prevent the spread of nuclear weapons. Non-proliferation is a political problem and must, therefore, be solved by political means. The reasons why countries want nuclear weapons - whether to meet their real or perceived security requirements or for political prestige - must be removed. Resolution of regional conflicts would diminish the stimulus for proliferation, while significant nuclear disarmament measures would de-emphasize the role of nuclear weapons in international politics. Meanwhile, institutional arrangements could minimize the risks of nuclear weapon proliferation. One such arrangement could be the internationalization of the sensitive, that is, the most proliferation-prone, elements of the nuclear fuel cycle. This book analyses some of the political, economic, technical and legal issues involved in internationalizing the nuclear fuel cycle. It consists of two parts. Part I is SIPRI's (Stockholm International Peace Research Institute) evaluation of the advantages, as well as the weaknesses, of the existing proposals for internationalization. Part II contains the papers contributed to the SIPRI symposium on 'internationalization of the nuclear fuel cycle', which was held in October/ November 1979. (author)

Disposition of weapons-grade plutonium in Westinghouse reactors

Alsaed, A.A.; Adams, M.

1998-03-01

The authors have studied the feasibility of using weapons-grade plutonium in the form of mixed-oxide (MOX) fuel in existing Westinghouse reactors. They have designed three transition Cycles from an all LEU core to a partial MOX core. They found that four-loop Westinghouse reactors such as the Vogtle power plant are capable of handling up to 45 percent weapons-grade MOX loading without any modifications. The authors have also designed two kinds of weapons-grade MOX assemblies with three enrichments per assembly and four total enrichments. Wet annular burnable absorber (WABA) rods were used in all the MOX feed assemblies, some burned MOX assemblies, and some LEU feed assemblies. Integral fuel burnable absorber (IFBA) was used in the rest of the LEU feed assemblies. The average discharge burnup of MOX assemblies was over 47,000 MWD/MTM, which is more than enough to meet the open-quotes spent fuel standard.close quotes One unit is capable of consuming 0.462 MT of weapons-grade plutonium per year. Preliminary analyses showed that important reactor physics parameters for the three transitions cycles are comparable to those of LEU cores including boron levels, reactivity coefficients, peaking factors, and shutdown margins. Further transient analyses will need to be performed

Chloline- and oxytetracycline reactions with iodide-131-and bromide-82-ions in methanol and acetone are studied. It is established that labelled compounds reveal tetracycline (TC) properties in pharmacokinetic experiments on laboratory animals for 20-25 hours after synthesis; the yield of purposeful preparations for radioactive isotopes is 90-95%. Kinetic dependences of iodine-131 and bromine-82-TC yield on acidity and temperature of medium are presented. TC radiation resistance in solutions and in solid state at different temperatures in the range of absorbed doses of 1-10 Mrad is investigated. The possibility of TC radiation sterilization is shown

Measures to implement the Chemical Weapons Convention

This seminar is another excellent opportunity for those involved in preventing chemical weapons production and use to learn from each other about how the Chemical Weapons Convention (CWC) can become a foundation of arms control in Africa and around the world. The author is grateful to the staff of the Organization for the Prohibition of Chemical Weapons (OPCW) for inviting him to address this distinguished seminar. The views expressed in this paper are those of the authors alone, and do not represent the position of the government of the US nor or of any other institution. In 1993, as the process of CWC ratification was beginning, concerns arose that the complexity of integrating the treaty with national law would cause each nation to implement the Convention without regard to what other nations were doing, thereby causing inconsistencies among States Parties in how the Convention would be carried out. As a result the Manual for National Implementation of the Chemical Weapons Convention was prepared and presented it to each national delegation at the December 1993 meeting of the Preparatory Commission in The Hague. During its preparation, the Manual was reviewed by the Committee of Legal Experts on National Implementation of the Chemical Weapons Convention, a group of distinguished international jurists, law professors, legally-trained diplomats, government officials, and Parliamentarians from every region of the world, including Mica. In February 1998, the second edition of the Manual was published in order to update it in light of developments since the CWC entered into force on 29 April 1997. The second edition 1998 clarified the national implementation options to reflect post-entry-into-force thinking, added extensive references to national implementing measures that had been enacted by various States Parties, and included a prototype national implementing statute developed by the authors to provide a starting point for those whose national implementing

2006-07-01

Nuclear, biological and chemical weapons are rightly called weapons of mass destruction (WMD). Designed to terrify as well as destroy, they have the potential to kill thousands and thousands of people in a single attack, and their effects may persist in the environment and in our bodies, in some cases indefinitely. Many efforts have been made to free the world from the threat of these weapons and some progress has been made. Paradoxically, despite the end of the Cold War, the past decade has seen more setbacks than successes. States have failed to comply with their disarmament and non-proliferation commitments, and terrorist groups have emerged that recognize no restraints. In September 2005, the United Nations World Summit was unable to agree on a single recommendation on disarmament and non-proliferation. It is time for all to wake up to the awesome reality that many of the old threats continue to hang over the world and that many new ones have emerged. It is time for all governments to revive their cooperation and to breathe new life into the disarmament work of the United Nations. Efforts to eradicate poverty and to protect the global environment must be matched by a dismantling of the world's most destructive capabilities. The gearshift now needs to be moved from reverse to drive. Biological and chemical weapons have been comprehensively outlawed through global conventions, but these need to be universally accepted and fully implemented. Nuclear weapons must also be outlawed. Before this aim is realized, there must be new initiatives to reduce the number of nuclear weapons and the threat posed by them. It is equally urgent to prevent proliferation and to take special measures to ensure that terrorists do not acquire any weapons of mass destruction. This report presents ideas and recommendations on what the world community - including national governments and civil society - can and should do.

Plus c'est la meme chose: The future of nuclear weapons in Europe

International Nuclear Information System (INIS)

Maaranen, S.A.

1996-01-01

Since the end of the Cold War, the United States perhaps more than any other nuclear weapon state has deeply questioned the future role of nuclear weapons, both in a strategic sense and in Europe. It is probably the United States that has raised the most questions about the continuing need for and efficacy of nuclear weapons, and has expressed the greatest concerns about the negative consequences of continuing nuclear weapons deployment. In the US, this period of questioning has now come to a pause, if not a conclusion. In late 1994 the United States decided to continue to pursue reductions in numbers of nuclear weapons as well as other changes designed to reduce the dangers associated with the possession of nuclear weapons. But at the same time the US concluded that some number of nuclear forces would continue to be needed for national security for the foreseeable future. These necessary nuclear forces include a continuing but greatly reduced stockpile of nuclear bombs deployed in Europe under NATO's New Strategic Concept. If further changes to the US position on nuclear weapons in Europe are to occur, it is likely to be after many years, and only in the context of dramatic additional improvements in the political and geo-political climate in and around Europe. The future role of nuclear weapons in Europe, as discussed in this report, depends in part on past and future decisions by the United States. but it must also be noted that other states that deploy nuclear weapons in Europe--Britain, France, and Russia, as well as the NATO alliance--have shown little inclination to discontinue their deployment of such weapons, whatever the United States might choose to do in the future

Seaborne Delivery Interdiction of Weapons of Mass Destruction (WMD)

Energy Technology Data Exchange (ETDEWEB)

Glauser, H

2011-03-03

Over the next 10-20 years, the probability of a terrorist attack using a weapon of mass destruction (WMD) on the United States is projected to increase. At some point over the next few decades, it may be inevitable that a terrorist group will have access to a WMD. The economic and social impact of an attack using a WMD anywhere in the world would be catastrophic. For weapons developed overseas, the routes of entry are air and sea with the maritime vector as the most porous. Providing a system to track, perform a risk assessment and inspect all inbound marine traffic before it reaches US coastal cities thereby mitigating the threat has long been a goal for our government. The challenge is to do so effectively without crippling the US economy. The Portunus Project addresses only the maritime threat and builds on a robust maritime domain awareness capability. It is a process to develop the technologies, policies and practices that will enable the US to establish a waypoint for the inspection of international marine traffic, screen 100% of containerized and bulk cargo prior to entry into the US if deemed necessary, provide a palatable economic model for transshipping, grow the US economy, and improve US environmental quality. The implementation strategy is based on security risk, and the political and economic constraints of implementation. This article is meant to provide a basic understanding of how and why this may be accomplished.

In recent years, global warming has attracted great attention around the world. Temperature change is not only involved in global climate change but also closely linked to economic development, the ecological environment, and agricultural production. In this study, based on temperature data recorded by 756 meteorological stations in China during 1951-2013, the spatial and temporal stability characteristics of annual temperature in China and its first-level basins were investigated using the rank correlation coefficient method, the relative difference method, rescaled range (R/S) analysis, and wavelet transforms. The results showed that during 1951-2013, the spatial variation of annual temperature belonged to moderate variability in the national level. Among the first-level basins, the largest variation coefficient was 114% in the Songhuajiang basin and the smallest variation coefficient was 10% in the Huaihe basin. During 1951-2013, the spatial distribution pattern of annual temperature presented extremely strong spatial and temporal stability characteristics in the national level. The variation range of Spearman's rank correlation coefficient was 0.97-0.99, and the spatial distribution pattern of annual temperature showed an increasing trend. In the national level, the Liaohe basin, the rivers in the southwestern region, the Haihe basin, the Yellow River basin, the Yangtze River basin, the Huaihe basin, the rivers in the southeastern region, and the Pearl River basin all had representative meteorological stations for annual temperature. In the Songhuajiang basin and the rivers in the northwestern region, there was no representative meteorological station. R/S analysis, the Mann-Kendall test, and the Morlet wavelet analysis of annual temperature showed that the best representative meteorological station could reflect the variation trend and the main periodic changes of annual temperature in the region. Therefore, strong temporal stability characteristics exist for

The German Debate on Tactical Nuclear Weapons

International Nuclear Information System (INIS)

Meier, Olivier

2008-01-01

This report analyses the debate in Germany about tactical nuclear weapons deployments in Europe. It is mainly based on interviews conducted with senior officials from the German Federal Foreign Ministry, the Federal Ministry of Defence, senior members of Parliament as well as experts from research institutes and think-tanks. The interviews focused on the more recent past in the German debate as well as the future of tactical nuclear weapon deployments in Germany and Europe. The report concludes that while a change of Germany's position on tactical nuclear weapons is unlikely to change in the short-term, several developments will make it unlikely that the continued involvement of Germany in NATO nuclear sharing will have to be debated in the medium term. Should the next Parliamentary elections, which will take place in 2009 at the latest, result in a Social Democrat-led government, a push for a reduction of Germany's involvement in NATO nuclear sharing appears possible. A conservative-led government is likely to maintain the nuclear status quo within NATO

The immediate need for US universities to promote research related to a nuclear-weapon-free world

International Nuclear Information System (INIS)

Ionno, S.

1999-01-01

If disarmament is a goal, then the requisite skills must be fostered in academic research. Too many students today view nuclear weapons as a non-issue. It is crucial that those people in positions of influence encourage more young people to explore in-depth the political, scientific, and social changes that a nuclear-weapon-free world will require. The data presented are based on a search of nuclear-weapons-related keywords in the UMI Dissertation Abstracts Database which includes work from over 1000 North American graduate schools and European Universities. The search was focused on US Phd dissertations between 1987 and 1996. There was no PhDs focused on issues such as: zero-level nuclear-weapons-free world; nuclear-weapons-free zones; decreasing nuclear alert status; a nuclear weapons convention; no-first-use or-no use against non-nuclear-weapons-states; START; French nuclear weapons; a possible 'Eurobomb'; peace groups outside the USA, UK, and Germany; nuclear-weapons secrecy; funding disarmament; the role od UN in a nuclear-weapons-free world; an so on

Comprehensive study on nuclear weapons. Summary of a United Nations study

International Nuclear Information System (INIS)

1991-01-01

In December 1988, by resolution 43/75N, the United Nations General Assembly requested the Secretary-General to carry out a comprehensive update of a 1980 study on nuclear weapons. The study was to take into account recent relevant studies, and consider the political, legal and security aspects of: (a) nuclear arsenals and pertinent technological developments; (b) doctrines concerning nuclear weapons; (c) efforts to reduce nuclear weapons; (d) physical, environmental, medical and other effects of the use of nuclear weapons and of nuclear testing; (e) efforts to achieve a comprehensive nuclear-test ban; (f) efforts to prevent the use of nuclear weapons and their horizontal and vertical proliferation; and (g) the question of verification of compliance with nuclear-arms limitation agreements. The Group's report is presented in nine chapters, eight of which are summarized here; chapter 9, entitled ''Conclusions'', is included in its entirety. In his foreword to the report, the Secretary-General observes that the study represents the most comprehensive review of the relevant developments in the field over the last decade and was carried out during a period of ''far-reaching changes in international relations'' and an ''unprecedented evolution in the relationship between East and West''. This period experienced for the first time the initiation of an effective process of reduction of nuclear weapon stockpiles

Fourth and Fifth Amendment issues raised by Chemical Weapons Convention inspections

Energy Technology Data Exchange (ETDEWEB)

Tanzman, E.A. [Argonne National Lab., IL (United States). Economics and Law Section

1994-10-21

The Chemical Weapons Convention (CWC) offers a unique challenge to the United States system of constitutional law. This discussion is about the Fourth and Fifth Amendment issues raised by the CWC and about how federal implementing legislation can allow verification inspections to take place in the United States under the Chemical Weapons Convention while remaining in compliance with the Constitution. By implementing legislation, the author means a federal statute that would be enacted separately from Senate approval of the Convention itself. Although implementing legislation is a relatively unusual accompaniment to a treaty, it will be necessary to the CWC, and the Administration has submitted a bill that was under consideration in the last Congress and presumably will be reintroduced early next year. The Fourth and Fifth Amendment problems posed by the CWC arise from the verification inspection scheme embodied in the treaty. The CWC depends heavily on on-site inspections to verify compliance with its key requirements. These include destroying all chemicals weapons stockpiles and bringing potential chemical weapons precursors under international control. The Convention contains four distinct kinds of inspections: systematic inspections of chemical weapons storage and destruction facilities, routine inspections of various declared facilities, challenge inspections, and a variant on challenge inspections in cases of alleged use of chemical weapons. All inspections are supposed to be only as intrusive as necessary to carry out the Convention. These inspections will be carried out by inspectors employed by the Organization for the Prohibition of Chemical Weapons (OPCW), located in The Hague, which is responsible for enforcing the Convention. Generally, the inspected State Party is permitted to assign observers to accompany the inspectors.

Nuclear weapon testing and the monkey business

Murthy, M.S.S.

1978-01-01

Reasons for India's total ban on the export of rhesus monkeys to U.S. have been explained. The major reason is that some of the animals were used in nuclear weapon related radiation experiments. This was a clear violation of a stricture in the agreement about supply of monkeys. The stricture prohibited the use of animals for research concerning military operations, including nuclear weapon testing. It is pleaded that a strict enforcement of strictures rather than a total ban on the export of monkeys would be better in the interest of advancement of knowledge in human medicine and disease control.

Eckert, Michael

2013-01-01

Arnold Sommerfeld (1868-1951) belongs with Max Planck (1858-1947), Albert Einstein (1879-1955) and Niels Bohr (1885-1962) among the founders of modern theoretical physics, a science that developed into a budding discipline during his lifetime. Sommerfeld witnessed many of the most dramatic scientific, cultural and political events of this era. His correspondence with his family offers a vivid testament to the challenges and joys of a life in science. This biography attempts to reconstruct Sommerfeld’s life and work not only from the perspective of his achievements in theoretical physics but also with the goal of portraying the career of a scientist within the social and political environment in which it evolved. It is based to a large extent on Sommerfeld’s voluminous correspondence, which sheds light both on his private and scientific life. Furthermore, it provides an authentic view on the circumstances that shaped Sommerfeld’s career in different places – Königsberg, Göttingen, Clausthal, Aachen, ...

On February 25, 2009, flight TK 1951, a Boeing 737-800 operated by Turkish Airlines, crashed approximately 1.5 km before the intended runway at Amsterdam Schiphol Airport. On board were 135 people-128 passengers and 7 crew. Of these 9 were killed and 86 were injured. The aircraft was destroyed. The official inquiry into the cause of the accident is being conducted by the Dutch Safety Board (Onderzoeksraad Voor Veiligheid, OvV). Prior to the accident the Netherlands Ministry of Transport, Public Works and Water Management had already embarked on a project to model the accident genesis of air transport accidents with the aim of quantifying the risks of air traffic and supporting the development of further measures and methods to reduce these risks. In this paper information regarding the accident is confronted with an analysis using the Causal model for Air Transport Safety (CATS). This enables drawing of some more theoretical conclusions about the accident and about the validity of CATS.

Full Text Available Abstract The purpose of this article is to analyze the presence of Ortega y Gasset in the Parana’s State group during the 1950s, especially his influence in the thinking of Wilson Martins, and to emphasize the debate on the ideas of the intellectual and the university. The article discusses about the contributions of this Parana’s thinker on the Parana’s university teaching constituting and organizing process, and emphasizes that the Wilson Martins’ role consisted in promoting the debate on the presence of the intellectual person in modern society, attributing the mission as guardian of the moral and herald of cultural renovation, without forgetting the Brazilian and European political-cultural context as the founding background to higher education. It bases itself on the speech entitled “The rebellion against intelligence and the mission of the university”, that occurred at the University of Parana in 1951, and on the work The History of Brazilian Intelligence, written by Wilson Martins.

Between Allies and Rivals: Turkey, Nuclear Weapons, and BMD

International Nuclear Information System (INIS)

Kibaroglu, Mustafa

2014-01-01

This paper discusses Turkey's attitudes vis-a-vis nuclear weapons and Ballistic Missile Defense in the light of recent developments in the Iranian nuclear program and NATO's evolving concept of extended deterrence. On the one hand, the long-standing forward deployment of US tactical nuclear weapons in Turkey and the country's role in the US Phased Adaptive Approach BMD architecture are still considered to be key elements of national security. On the other, security guarantees offered to Turkey by NATO and the US appear less and less credible in the face of rising regional threats. As this paper shows, there is a growing gap between official policy and public perceptions inside Turkey vis-a-vis the US, Iran, and nuclear weapons, as well as a growing Turkish aspiration to autonomy in its security and defense policy. While one should not expect Turkey to develop nuclear weapons anytime soon, an unchecked Iranian regional power could bring Ankara to hedge its bets in the long term. Turkey's controversial recent decision to buy a Chinese system for its national air and missile defense rather than European or US equipment should be seen in the light of this search for autonomy.

International agreements on nuclear weapons

International Nuclear Information System (INIS)

Dombey, N.

1982-01-01

The satellite detection of a nuclear explosion in the South Atlantic and Israel's destruction of a research reactor in Iraq make it essential to strengthen existing monitoring and enforcement programs to prevent proliferation. While there was no reliable evidence that either South Africa or Iraq was violating non-proliferation agreements, worst case scenarios can demonstrate to unfriendly countries that South Africa had diverted fuel to test a nuclear weapon and that Iraq is intending to produce weapons-grade plutonium 239. The situation can be improved by formulating better terms and conditions for internationalizing access to materials. Nuclear suppliers need to agree on terms that will assure their customers that contracts for civil programs will be honored. The International Atomic Energy Agency (IAEA), which includes both nuclear suppliers and customers, could achieve stronger agreements that take into account recent technological advances that will expand enrichment and reprocessing activities. 23 references, 1 figure

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

International Nuclear Information System (INIS)

Pollack, J.D.

2010-01-01

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

Military descentralization of Latin America will constitute a measure that will keep its peoples from squandering in nuclear weapons out of their limited resources and will protect them from eventually being attacked in such fashion within their territories. This constitutes a considerable contribution award avoiding proliferation of nuclear weapons as well as a giant step towards general and complete disarmament. It will also constitute evidence that Latin America, faithful to its universalist tradition, not only must make a greater effort towards proscribing from its territories the treat of a nuclear war, but also must use all its resources to persevere in its struggle for welfare and progress of its peoples, cooperating along with the rest of the world to achieve the ideals of mankind as a whole

Linking legacies: Connecting the Cold War nuclear weapons production processes to their environmental consequences

International Nuclear Information System (INIS)

1997-01-01

In the aftermath of the Cold War, the US has begun addressing the environmental consequences of five decades of nuclear weapons production. In support of this effort, the National Defense Authorization Act for Fiscal Year 1995 directed the Department of Energy (DOE) to describe the waste streams generated during each step in the production of nuclear weapons. Accordingly, this report responds to this mandate, and it is the Department's first comprehensive analysis of the sources of waste and contamination generated by the production of nuclear weapons. The report also contains information on the missions and functions of nuclear weapons facilities, on the inventories of waste and materials remaining at these facilities, as well as on the extent and characteristics of contamination in and around these facilities. This analysis unites specific environmental impacts of nuclear weapons production with particular production processes. The Department used historical records to connect nuclear weapons production processes with emerging data on waste and contamination. In this way, two of the Department's legacies--nuclear weapons manufacturing and environmental management--have become systematically linked. The goal of this report is to provide Congress, DOE program managers, non-governmental analysts, and the public with an explicit picture of the environmental results of each step in the nuclear weapons production and disposition cycle

This article evaluates the threat of massive destruction weapons (nuclear, chemical, biological) for Europe and recalls the existing safeguards against the different forms of nuclear proliferation: legal (non-proliferation treaty (NPT), comprehensive nuclear test ban treaty (CTBT), fissile material cut off treaty (FMCT) etc..), technical (fabrication of fissile materials, delays). However, all these safeguards can be overcome as proven by the activities of some countries. The situation of proliferation for the other type of massive destruction weapons is presented too. (J.S.)

This dissertation provides a history of Canadian ideas about nuclear weapons from the late 1950s until the end of the Trudeau era in 1984. Throughout this period, Canadians reacted to the insecurity they felt in the world around them by expressing many conflicting, often irreconcilable views about a range of nuclear weapon issues, including Canada's acquisition of nuclear warheads in 1963, the U.S. ABM program in the 1960s and early 1970s, the role of Canadian nuclear technology in the development of India's first nuclear explosion, and the Trudeau government's decision to allow the U.S. military to test cruise missiles in northern Canada The dissertation concludes with an examination of the emergence of a broadly-based, increasingly mainstream and influential anti-nuclear movement in the early 1980s, the clearest manifestation of the insecurity Canadians experienced at the time. .The nuclear debates examined in this dissertation reveal that Canadians were divided over nuclear weapons, nuclear strategy, the arms race, proliferation, and arms control and disarmament. In particular, they came to fundamentally different conclusions about how Canada's nuclear weapon policies, and its support for the nuclear policies of its alliances, would contribute to international stability and order. Some believed that their security rested on the maintenance of a strong Western nuclear deterrent and supported Canada contributing to its credibility; others believed that the constant modernisation of nuclear arsenals fuelled by the superpower arms race posed a serious threat to their security. This conceptual dilemma-the security through nuclear strength argument versus the fear that the quest for security through quantitative and qualitative improvements of nuclear stockpiles increased the likelihood of nuclear war-left Canadians divided over the value and utility of nuclear weapons and the strategies developed around them.

Excess Weapons Plutonium Immobilization in Russia

International Nuclear Information System (INIS)

Jardine, L.; Borisov, G.B.

2000-01-01

The joint goal of the Russian work is to establish a full-scale plutonium immobilization facility at a Russian industrial site by 2005. To achieve this requires that the necessary engineering and technical basis be developed in these Russian projects and the needed Russian approvals be obtained to conduct industrial-scale immobilization of plutonium-containing materials at a Russian industrial site by the 2005 date. This meeting and future work will provide the basis for joint decisions. Supporting R and D projects are being carried out at Russian Institutes that directly support the technical needs of Russian industrial sites to immobilize plutonium-containing materials. Special R and D on plutonium materials is also being carried out to support excess weapons disposition in Russia and the US, including nonproliferation studies of plutonium recovery from immobilization forms and accelerated radiation damage studies of the US-specified plutonium ceramic for immobilizing plutonium. This intriguing and extraordinary cooperation on certain aspects of the weapons plutonium problem is now progressing well and much work with plutonium has been completed in the past two years. Because much excellent and unique scientific and engineering technical work has now been completed in Russia in many aspects of plutonium immobilization, this meeting in St. Petersburg was both timely and necessary to summarize, review, and discuss these efforts among those who performed the actual work. The results of this meeting will help the US and Russia jointly define the future direction of the Russian plutonium immobilization program, and make it an even stronger and more integrated Russian program. The two objectives for the meeting were to: (1) Bring together the Russian organizations, experts, and managers performing the work into one place for four days to review and discuss their work with each other; and (2) Publish a meeting summary and a proceedings to compile reports of all the

Physics studies of weapons plutonium disposition in the IFR closed fuel cycle

International Nuclear Information System (INIS)

Hill, R.N.; Wade, D.C.; Liaw, J.R.; Fujita, E.K.

1994-01-01

The core performance impact of weapons plutonium introduction into the IFR closed fuel cycle is investigated by comparing three disposition scenarios: a power production mode, a moderate destruction mode, and a maximum destruction mode all at a constant heat rating of 840 MWt. For each scenario, two fuel cycle models are evaluated: cores using weapons material as the sole source of transuranics in a once-through mode, and recycle corns using weapons material only as required for a make-up feed. Calculated results include mass flows, detailed isotopic distributions, neutronic performance characteristics, and reactivity feedback coefficients. In general, it is shown that weapons plutonium feed does not have an adverse impact on IFR core performance characteristics

A open-quotes Newclose quotes regime for nuclear weapons and materials

International Nuclear Information System (INIS)

Sutcliffe, W.G.

1994-01-01

In this paper, I discuss the principal ideas that I covered in my presentation on December 8, 1993, at the Future of Foreign Nuclear Materials Symposium held by the Naval Postgraduate School in Monterey, California. I was asked to discuss issues related to military inventories of plutonium, and I took this opportunity to describe a possible declaratory regime that could encompass military as well as civilian inventories of plutonium. The open-quote newclose quotes in the title does not imply that the regime discussed here is an original idea. Rather, the regime will be open-quotes new,close quotes when it is adopted. The regime proposed here and in other works is one in which all stocks of nuclear weapons and materials are declared. Originally, declarations were proposed as a traditional arms control measure. Here, declarations are proposed to support the prevention of misuse of nuclear weapons and materials, including support for the nonproliferation regime. In the following, I discuss: (1) Worldwide inventories of nuclear weapons and materials, including the fact that military plutonium must be viewed as part of that worldwide inventory. (2) Life cycles of nuclear weapons and materials, including the various stages from the creation of nuclear materials for weapons through deployment and retirement of weapons to the final disposition of the materials. (3) Mechanisms for making declarations. (4) Risks and benefits to be derived from declarations. (5) Possibilities for supporting evidence or verification

Generator-produced Rb-82, a 75-sec positron emitter with potential for myocardial blood-flow imaging, was studied with various ion-exchange columns to evaluate the characteristics of alumina as an adsorber for the 25-day Sr-82 parent. Test columns of alumina, Bio Rex 70, and Chelex 100 were loaded with multimillicurie amounts of no-carrier-added Sr-82/Sr-85 (Sr-85 is a production contaminant). The breakthrough of Sr-82/Sr-85, and the yield of Rb-82, were determined for long-term elutions from each column with up to 4 liter of 2% NaCl solution at pH 8 to 9. The breakthrough of Sr-82/85 was 10 -6 to 10 -5 from alumina and 10 -6 to 10 -4 from Chelex 100 and Bio Rex 70. The effects of eluent flow rate and concentration, and of alumina volume, on the breakthrough and yield were also studied. An improved and automated Rb-82 generator was used for myocardial and brain blood-flow studies in experimental animals and in man; it was equipped with solenoid flow-control valves and five in. of lead shielding for the alumina columns, which were charged with 25 to 50 mCi Sr-82 (100 to 150 mCi Sr-85). The Rb-82 generator with alumina column provided up to 20 to 40 mCi of Rb-82 as often as every 5 to 10 min with -5 breakthrough of Sr-82/85 over the 2- to 3-mo, useful life of the generator

A system for detection and treatment of chemical weapons and/or biological pathogens uses a detector system, an electrostatic precipitator or scrubber, a circulation system, and a control. The precipitator or scrubber is activated in response to a signal from the detector upon the detection of chemical weapons and/or biological pathogens.

The Chemical Weapons Convention -- Legal issues

Energy Technology Data Exchange (ETDEWEB)

NONE

1997-08-01

The Chemical Weapons Convention (CWC) offers a unique challenge to the US system of constitutional law. Its promise of eliminating what is the most purely genocidal type of weapon from the world`s arsenals as well as of destroying the facilities for producing these weapons, brings with it a set of novel legal issues. The reservations about the CWC expressed by US business people are rooted in concern about safeguarding confidential business information and protecting the constitutional right to privacy. The chief worry is that international verification inspectors will misuse their power to enter commercial property and that trade secrets or other private information will be compromised as a result. It has been charged that the Convention is probably unconstitutional. The author categorically disagrees with that view and is aware of no scholarly writing that supports it. The purpose of this presentation is to show that CWC verification activities can be implemented in the US consistently with the traditional constitutional regard for commercial and individual privacy. First, he very briefly reviews the types of verification inspections that the CWC permits, as well as some of its specific privacy protections. Second, he explains how the Fourth Amendment right to privacy works in the context of CWC verification inspections. Finally, he reviews how verification inspections can be integrated into these constitutional requirements in the SU through a federal implementing statute.

Nuclear weapons and the World Court ruling

International Nuclear Information System (INIS)

Singh, J.

1998-01-01

based on the initiatives by non-governmental organizations, the World Health Organisation (WHO) Assembly asked the International Court of Justice for an advisory opinion in 1993 whether, considering the environmental and health consequences, the use of nuclear weapons by a state in war or other armed conflict would be a breach of its obligations under international law. The World Court decided that it was not able to give an advisory opinion as requested, because of the fact that questions of use of force and such like were beyond the scope of specialized agencies like the WHO. The Court has ruled that the international community, especially the five nuclear weapon states have not only an obligation to negotiate a treaty for total nuclear disarmament, but also have an obligation to conclude such treaty. We may expect that the nuclear weapon states will cynically disregard the ruling of the World Court as they have been doing to the basic obligation itself in pursuit of nuclear hegemony. But the remaining 150 countries or so also bear a responsibility to keep nudging the recalcitrant states into implementing their commitments to disarm

Low yield nuclear weapons and nuclear terrorism

International Nuclear Information System (INIS)

Rodionov, S.

1999-01-01

It is unlikely that anybody would imagine the route to a nuclear-weapon-free world as a straight and unimpeded one. At the moment, there is a fading interest in the possibility of the concerted bilateral reduction of the US and Russian nuclear weapon stockpiles. The reason is evident: these powers demonstrate quite different approaches to two large political campaigns initiated in American political circles, namely NATO expansion to the East, and the attack on Anti-Ballistic-Missile (ABM) Treaty. Russia considers these initiatives as provocative in content and high-handed in the form. The West argues that Russian response is unjustified and insists on the peaceful nature of its plans?

Selection on an extreme weapon in the frog-legged leaf beetle (Sagra femorata).

O'Brien, Devin M; Katsuki, Masako; Emlen, Douglas J

2017-11-01

Biologists have been fascinated with the extreme products of sexual selection for decades. However, relatively few studies have characterized patterns of selection acting on ornaments and weapons in the wild. Here, we measure selection on a wild population of weapon-bearing beetles (frog-legged leaf beetles: Sagra femorata) for two consecutive breeding seasons. We consider variation in both weapon size (hind leg length) and in relative weapon size (deviations from the population average scaling relationship between hind leg length and body size), and provide evidence for directional selection on weapon size per se and stabilizing selection on a particular scaling relationship in this population. We suggest that whenever growth in body size is sensitive to external circumstance such as nutrition, then considering deviations from population-level scaling relationships will better reflect patterns of selection relevant to evolution of the ornament or weapon than will variation in trait size per se. This is because trait-size versus body-size scaling relationships approximate underlying developmental reaction norms relating trait growth with body condition in these species. Heightened condition-sensitive expression is a hallmark of the exaggerated ornaments and weapons favored by sexual selection, yet this plasticity is rarely reflected in the way we think about-and measure-selection acting on these structures in the wild. © 2017 The Author(s).

Anderson, Peter D

2012-02-01

The potential for chemical weapons to be used in terrorism is a real possibility. Classes of chemical weapons include nerve agents, vesicants (blister agents), choking agents, incapacitating agents, riot control agents, blood agents, and toxic industrial chemicals. The nerve agents work by blocking the actions of acetylcholinesterase leading to a cholinergic syndrome. Nerve agents include sarin, tabun, VX, cyclosarin, and soman. The vesicants include sulfur mustard and lewisite. The vesicants produce blisters and also damage the upper airways. Choking agents include phosgene and chlorine gas. Choking agents cause pulmonary edema. Incapacitating agents include fentanyl and its derivatives and adamsite. Riot control agents include Mace and pepper spray. Blood agents include cyanide. The mechanism of toxicity for cyanide is blocking oxidative phosphorylation. Toxic industrial chemicals include agents such as formaldehyde, hydrofluoric acid, and ammonia.

Nuclear power and nuclear weapon proliferation

International Nuclear Information System (INIS)

Apold, A.

1978-01-01

The theme of Dr. Marshall's lecture was that it is, from the viewpoint of prevention of proliferation of nuclear weapons,preferable to use plutonium as a fuel in FBR reactors rather than store it in what, in effect, would be plutonium mines. The true threat of proliferation lies in uranium enrichment. The FBR reactor is misunderstood and the US policy is not against breeders as such. Safeguards against the misuse of plutonium by leaving a residue of radioactivity after reprocessing is quite feasible, despite certain practical problems and extra costs. Weapon proliferation is subject to political objectives and intentions. Definite proposals are, (a) a limited number of reprocessing centres, (b) an accelerated development of FBR reactors, (c) a new FBR fuel cycle, (d) stop storage of spent thermal reactor fuel, (e) reinforced safeguards.

Measurement techniques for the verification of excess weapons materials

International Nuclear Information System (INIS)

Tape, J.W.; Eccleston, G.W.; Yates, M.A.

1998-01-01

The end of the superpower arms race has resulted in an unprecedented reduction in stockpiles of deployed nuclear weapons. Numerous proposals have been put forward and actions have been taken to ensure the irreversibility of nuclear arms reductions, including unilateral initiatives such as those made by President Clinton in September 1993 to place fissile materials no longer needed for a deterrent under international inspection, and bilateral and multilateral measures currently being negotiated. For the technologist, there is a unique opportunity to develop the technical means to monitor nuclear materials that have been declared excess to nuclear weapons programs, to provide confidence that reductions are taking place and that the released materials are not being used again for nuclear explosive programs. However, because of the sensitive nature of these materials, a fundamental conflict exists between the desire to know that the bulk materials or weapon components in fact represent evidence of warhead reductions, and treaty commitments and national laws that require the protection of weapons design information. This conflict presents a unique challenge to technologists. The flow of excess weapons materials, from deployed warheads through storage, disassembly, component storage, conversion to bulk forms, and disposition, will be described in general terms. Measurement approaches based on the detection of passive or induced radiation will be discussed along with the requirement to protect sensitive information from release to unauthorized parties. Possible uses of measurement methods to assist in the verification of arms reductions will be described. The concept of measuring attributes of items rather than quantitative mass-based inventory verification will be discussed along with associated information-barrier concepts required to protect sensitive information

2006-11-01

The events of September 11, 2001, made citizens of the world acutely aware of disasters consequent to present-day terrorism. This is a war being waged for reasons obscure to many of its potential victims. The term "NBCs" was coined in reference to terrorist weapons of mass destruction, i.e., nuclear, biological and chemical. The currently accepted acronym is "CBRNE" which includes Chemical, Biological, Radiological, Nuclear, and Explosive weapons. Non-nuclear explosives are the most common terrorist weapon now in use. Nuclear and radiological weapons are beyond the scope of this publication, which focuses on the "CBEs", i.e. chemical, biological and explosive weapons. Although neurologists will not be the first responders to CBEs, they must know about the neurological effects in order to provide diagnosis and treatment to survivors. Neurological complications of chemical, biological and explosive weapons which have or may be used by terrorists are reviewed by international experts in this publication. Management and treatment profiles are outlined.

Weapons grade plutonium disposition in PWR, CANDU and FR

Deplech, M.; Tommasi, J.; Zaetta, A.

2000-01-01

In the frame work of the AIDA/MOX phase I/I/ program (1994-1997) between France and Russia, the disposition of plutonium in reactors was studied. The LWR (Light Water Reactor), FR (Fast reactors), CANDU (Heavy Water Reactors), HTR (High Temperature Reactors) options for using excess dismantled weapons plutonium for peaceful commercial nuclear power generating purposes offer some advantages over the remaining options (storage). The AIDA/MOX phase 1 program covers different topics, among which are the neutronic aspects of loading reactors with weapons-grade plutonium. The conclusions are that the weapon plutonium consumption is similar in the different type of reactors. However, the use of inert matrices allows to increase the mass balance for a same denaturing level. The use of Thorium as a matrix or special isotopes to increase the proliferation resistance prove to be insufficient. (author)

The words "chemical and biological weapons" (CBW) send a shiver down most spines these days. With the end of the Cold War, the possibility of a massive nuclear confrontation appears remote, so today many popular doomsday scenarios center on the aggressive use of chemical or biological warfare by rogue nations or terrorist groups. As exaggerated as some of the accounts are, with CBW cast as the latest unseen, unstoppable enemy, the threat posed by these weapons is all too real, and growing. Images p931-a PMID:10585899

Full Text Available Este trabajo examina la lucha del cuerpo médico colombiano contra las enfermedades 'venéreas' entre 1886 y 1951. En este período, Colombia sufrió procesos de urbanización, crecimiento de población, nacimiento de la industria y aparición de una clase media y de un proletariado urbano. Los médicos encontraron una conexión estrecha entre la difusión del contagio de la sífilis y la gonorrea, y el aumento del ejercicio de la prostitución en las ciudades. A finales del siglo XIX, los médicos y los organismos de higiene asumieron la prostitución como inevitable; en 1907 consiguieron reglamentarla y fundaron dispensarios para aplicar los tratamientos de mercurio y compuestos arsenicales. Hacia los años 1930 y 1940, la curación de las enfermedades venéreas se asumió como un deber estatal de defensa de la raza y a favor de la civilización y del progreso. Hacia 1950, el uso eficaz de la penicilina hizo que la cuestión de la prostitución se volviera a plantear en términos más morales y estéticos, y se impuso la abolición de las normas que regulaban su ejercicio, por lo menos en Bogotá.The article examines the Colombian medical field's fight against so-called venereal diseases between 1886 and 1951, a period when the country was undergoing processes of urbanization, population growth, and the emergence both of industry as well as of a middle class and an urban proletariat. Physicians found a close connection between the spread of syphilis and gonorrhea and the rise of prostitution in cities. At the close of the 19th century, doctors and public health bodies assumed prostitution was inevitable. In 1907 they managed to have it legalized and they opened clinics to dispense mercury therapy and treatment with arsenic compounds. Starting in the 1930s and 1940s, treatment of venereal diseases was viewed as the State's duty, necessary to protect "la raza" and safeguard progress and civilization.

Blaine, James W

2012-12-01

The growing concern over the potential use of biological agents as weapons and the continuing work of the Biological Weapons Convention has promoted an interest in establishing national biological laboratory biosafety and biosecurity monitoring programs. The challenges and issues that should be considered by governments, or organizations, embarking on the creation of a biological laboratory biosafety and biosecurity monitoring program are discussed in this article. The discussion focuses on the following questions: Is there critical infrastructure support available? What should be the program focus? Who should be monitored? Who should do the monitoring? How extensive should the monitoring be? What standards and requirements should be used? What are the consequences if a laboratory does not meet the requirements or is not willing to comply? Would the program achieve the results intended? What are the program costs? The success of a monitoring program can depend on how the government, or organization, responds to these questions.

Elimination of ballistic missiles: An important step towards a nuclear-weapon-free world

Although the Non-Proliferation Treaty preamble emphasises 'the elimination from national arsenals of nuclear weapons and the means of their delivery pursuant to a Treaty on general and complete disarmament under strict and effective international control', the Non-Proliferation Treaty does not further specify how this ultimate goal could be achieved for delivery systems. Delivery systems are an important and costly part of nuclear weapons which should be sophisticated, therefore the control of nuclear-capable delivery systems would be an important step to make nuclear weapons useless and reduce the threat od their use. This is especially true for ballistic missiles, which represent effective and powerful means to deploy nuclear weapons

Bozeman, William P; Hauda, William E; Heck, Joseph J; Graham, Derrel D; Martin, Brian P; Winslow, James E

2009-04-01

Conducted electrical weapons such as the Taser are commonly used by law enforcement agencies. The safety of these weapons has been the subject of scrutiny and controversy; previous controlled studies in animals and healthy humans may not accurately reflect the risks of conducted electrical weapons used in actual conditions. We seek to determine the safety and injury profile of conducted electrical weapons used against criminal suspects in a field setting. This prospective, multicenter, observational trial tracked a consecutive case series of all conducted electrical weapon uses against criminal suspects at 6 US law enforcement agencies. Mandatory review of each conducted electrical weapon use incorporated physician review of police and medical records. Injuries were classified as mild, moderate, or severe according to a priori definitions. The primary outcome was a composite of moderate and severe injuries, termed significant injuries. Conducted electrical weapons were used against 1,201 subjects during 36 months. One thousand one hundred twenty-five subjects (94%) were men; the median age was 30 years (range 13 to 80 years). Mild or no injuries were observed after conducted electrical weapon use in 1,198 subjects (99.75%; 95% confidence interval 99.3% to 99.9%). Of mild injuries, 83% were superficial puncture wounds from conducted electrical weapon probes. Significant injuries occurred in 3 subjects (0.25%; 95% confidence interval 0.07% to 0.7%), including 2 intracranial injuries from falls and 1 case of rhabdomyolysis. Two subjects died in police custody; medical examiners did not find conducted electrical weapon use to be causal or contributory in either case. To our knowledge, these findings represent the first large, independent, multicenter study of conducted electrical weapon injury epidemiology and suggest that more than 99% of subjects do not experience significant injuries after conducted electrical weapon use.

Confidence in Nuclear Weapons as Numbers Decrease and Time Since Testing Increases

Science.gov (United States)

Adams, Marvin

2011-04-01

As numbers and types of nuclear weapons are reduced, the U.S. objective is to maintain a safe, secure and effective nuclear deterrent without nuclear-explosive testing. A host of issues combine to make this a challenge. An evolving threat environment may prompt changes to security systems. Aging of weapons has led to ``life extension programs'' that produce weapons that differ in some ways from the originals. Outdated and changing facilities pose difficulties for life-extension, surveillance, and dismantlement efforts. A variety of factors can make it a challenge to recruit, develop, and retain outstanding people with the skills and experience that are needed to form the foundation of a credible deterrent. These and other issues will be discussed in the framework of proposals to reduce and perhaps eliminate nuclear weapons.

Multidepot UAV Routing Problem with Weapon Configuration and Time Window

Directory of Open Access Journals (Sweden)

Tianren Zhou

2018-01-01

Full Text Available In recent wars, there is an increasing trend that unmanned aerial vehicles (UAVs are utilized to conduct military attacking missions. In this paper, we investigate a novel multidepot UAV routing problem with consideration of weapon configuration in the UAV and the attacking time window of the target. A mixed-integer linear programming model is developed to jointly optimize three kinds of decisions: the weapon configuration strategy in the UAV, the routing strategy of target, and the allocation strategy of weapons to targets. An adaptive large neighborhood search (ALNS algorithm is proposed for solving the problem, which is tested by randomly generated instances covering the small, medium, and large sizes. Experimental results confirm the effectiveness and robustness of the proposed ALNS algorithm.

The Chemical Weapons Convention (CWC) was drafted with the recognition that it is impossible to envision every way in which toxic chemicals might be used for aggressive purposes. As terrorist organizations and rogue states replace the major powers as the most likely candidates to employ chemical weapons, the agents of choice may differ from those developed for battlefield use. Twenty- first century chemical warfare may target civilians or agricultural production, and clandestine production-facilities may manufacture toxic agents from chemical precursors, not monitored under the CWC control regime. The effects (on CWC implementation) of changing industrial technologies, including ongoing developments in chemical process technology, dual-use industrial chemicals, and rapid methods for discovering biologically active chemicals, are considerable Also considered is how commercial technologies could be misused for the development of novel chemical weapons, and how such abuses might be detected and monitored.

Western Option - Disarmament of Russian Weapon Plutonium

International Nuclear Information System (INIS)

Tveiten, B.; Petroll, M.R.

2002-01-01

The Western Option concept describes an approach to the conversion of weapon-grade plutonium from Russian nuclear warheads under the special aspects of meeting the criteria of irreversible utilization. Putting this concept of plutonium conversion into non-weapon-grade material into effect would make a major contribution to improving security worldwide. This study is based on an agreement between the Russian Federation and the United States of America concluded in September 2000. It provides for the conversion of 34 t of weapon-grade plutonium in each of the two states. This goal is also supported by other G8 countries. While the United States performs its part of the agreement under its sole national responsibility, the Russian program needs financial support by Western states. Expert groups have pointed out several options as a so-called basic scenario. The funds of approx. US Dollar 2 billion required to put them into effect have not so far been raised. The Western Option approach described in this contribution combines results of the basic scenario with other existing experience and with technical solutions available for plutonium conversion. One of the attractions of the Western Option lies in its financial advantages, which are estimated to amount to approx. US Dollar 1 billion. (orig.) [de

Deconstructing the 'energy weapon': Russia's threat to Europe as case study

International Nuclear Information System (INIS)

Smith Stegen, Karen

2011-01-01

As the likelihood increases that Russia will dominate the European Union's (EU) energy supply, questions have emerged as to whether Russia would use the energy weapon to influence EU member policies and extract political concessions. Countervailing voices argue that Russia would be restricted by interdependence and market forces. As of yet, no one has analyzed the assumptions underlying the energy weapon thesis. Moreover, many scholars examining EU-Russian energy relations rely on non-Russian data. This article seeks to fill several informational and theoretical gaps by including Russian sources and first-hand data and by systematically analyzing the conditions that must obtain before an energy supplier can successfully convert its energy resources into political power. The resulting model can be utilized to analyze the capacity of a supplier to use the energy weapon-whether it be Russia, Iran, Venezuela or any other energy heavyweight-and to assess whether the deployment was successful. Five purported cases of Russian manipulation are analyzed in this article and the findings indicate that, more often than not, Russia failed to achieve political concessions. Looking to the future, the plausibility of Russia using the energy weapon to exploit Europe's dependence, particularly on gas, is also examined. - Highlights: → Energy producers may manipulate supply and prices to coerce political concessions. → Energy weapon model: four conditions must obtain for successful deployment. → Western policy-makers worry about EU dependence on and vulnerability to Russia. → Analysis of five Russian cases reveals tenuous link between weapon use and success. → In medium term, EU can likely avoid yielding political autonomy for supply security.

Weapons-grade nuclear material - open questions of a safe disposal

There are suitable technologies available for destruction of weapons-grade uranium and plutonium. Weapons-grade uranium, consisting to 90% of the isotope U-235, can be diluted with the uranium isotope U-238 to make it non-weapons-grade, but it will then still be a material that can be used as a fuel in civil nuclear reactors. For safe plutonium disposal, several options are under debate. There is for instance a process called ''reverse reprocessing'', with the plutonium being blended with high-level radioactive fission products and then being put into a waste form accepted for direct ultimate disposal. The other option is to convert weapons-grade plutonium into MOX nuclear fuel elements and then ''burn'' them in civil nuclear power reactors. This is an option favoured by many experts. Such fuel elements should stay for a long time in the reactor core in order to achieve high burnups, and should then be ready for ultimate disposal. This disposal pathway offers essential advantages: the plutonium is used up or depleted as a component of reactor fuel, and thus is no longer available for illegal activities, and it serves as an energy source for power generation.

[Physicians, prostitution, and venereal disease in Colombia (1886-1951)].

Science.gov (United States)

Obregón, Diana

2002-01-01

The article examines the Colombian medical field's fight against so-called venereal diseases between 1886 and 1951, a period when the country was undergoing processes of urbanization, population growth, and the emergence both of industry as well as of a middle class and an urban proletariat. Physicians found a close connection between the spread of syphilis and gonorrhea and the rise of prostitution in cities. At the close of the 19th century, doctors and public health bodies assumed prostitution was inevitable. In 1907 they managed to have it legalized and they opened clinics to dispense mercury therapy and treatment with arsenic compounds. Starting in the 1930s amd 1940s, treatment of venereal diseases was viewed as the State's duty, necessary to protect "la raza" and safeguard progress and civilization. As of 1950, the efficient use of penicillin once again caused the question of prostitution to be posed in more moral and aesthetic terms and brought an end to the regulations groverning its practice, at least in Bogota.

The Nuclear Security Enterprise, managed by the National Nuclear Security Administration - a semiautonomous agency within the Department of Energy - has been associated with numerous assessments with respect to the estimating, management capabilities, and practices pertaining to nuclear weapon modernization efforts. This report identifies challenges in estimating and analyzing the Nuclear Security Enterprise through an analysis of analogous timeframe conditions utilizing two types of nuclear weapon data - (1) a measure of effort and (2) a function of time. The analysis of analogous timeframe conditions that utilizes only two types of nuclear weapon data yields four summary observations that estimators and analysts of the Nuclear Security Enterprise will find useful.

With funding from different parts of the federal government, the Integral Fast Reactor (IFR) project has survived into fiscal year 1994 and is now embarking on a demonstration of how this type of liquid-metal-cooled reactor (LMR) can be used to burn fuel derived from weapons-grade plutonium. This month, an assembly made from weapons-grade material is to be loaded into Experimental Breeder Reactor-II in Idaho, which is serving as the prototype for the IFR concept. Although FY 1994 work is being funded by the DOE, this particular examination of plutonium burnup is backed by the Department of Defense

This document contains two texts linked with the project of an international convention for the elimination of nuclear weapons (the text of this project has been sent to the UN General Secretary and is part of an international campaign to abolish nuclear weapons, ICAN). These two texts are contributions presented in London at the Global Summit for a Nuclear Weapon-free World. The first one calls into question the deterrence principle and the idea of a nuclear weapon-based security. It calls for different forms of action to promote a nuclear weapon-free world. The second text stresses the role and the responsibility of states with nuclear weapons in nuclear disarmament and in the reinforcement of the nuclear non proliferation treaty (NPT)

Homicide followed by the suicide of the offender is a well-known phenomenon. In most cases, it takes place in the context of the so-called "family tragedies." A recent series of such family tragedies in Switzerland prompted an intensive debate in the media and the Swiss government concerning the Swiss Weapon Law, in particular the requirement to keep personal army weapons at home. The present study of Homicide-Suicide cases in Switzerland, thus focuses on the role played by guns, especially military weapons, in such crimes. We investigated retrospectively 75 cases of Homicide-Suicide, comprising 172 individuals and spanning a period of 23 years in western and central Switzerland. Our results show that if guns were used in 76% of the cases, army weapons were the cause of death in 25% of the total. In 28% of the deaths caused by a gunshot, the exact type of the gun and its origin could not be determined. Thus, the majority of Homicide-Suicide cases in Switzerland involve the use of guns. The exact percentage of cases were military weapons were involved could not be defined. In our opinion, a stricter weapons law, restricting access to firearms, would be a factor of prevention of Homicide- Suicide cases in Switzerland.

The Future of Killing: Ethical and Legal Implications of Fully Autonomous Weapon Systems

Directory of Open Access Journals (Sweden)

Martin Lark

2017-03-01

Full Text Available Warfare is moving towards full weapon autonomy. Already, there are weapons in service that replace a human at the point of engagement. The remote pilot must adhere to the law and consider the moral and ethical implications of using lethal force. Future fully autonomous weapons will be able to search for, identify and engage targets without human intervention, raising the question of who is responsible for the moral and ethical considerations of using such weapons. In the chaos of war, people are fallible, but they can apply judgement and discretion and identify subtle signals. For example, humans can identify when an enemy wants to surrender, are burying their dead, or are assisting non-combatants. An autonomous weapon may not be so discerning and may not be capable of being programmed to apply discretion, compassion, or mercy, nor can it adapt commanders’ intent or apply initiative. Before fully autonomous weapons use lethal force, it is argued that there needs to be assurances that the ethical implications are understood and that control mechanisms are in place to ensure that oversight of the system is able to prevent incidents that could amount to breaches of the laws of armed conflict.

A six decades long follow-up on body size in adolescents from Zagreb, Croatia (1951-2010).

Most studies analysing the influence of socioeconomic deterioration on body size focus on the impact of food shortages and diseases on the growth in early childhood. To evaluate how socioeconomic conditions influence the growth during the adolescence, we tracked the body size of 15-19 year-olds over the last sixty years covering the socialist period (1951-1990), the war (1991-1995) and the transition to capitalistic economy. This study of Zagreb, Croatia, adolescent population provides information on the secular trend in height, weight and Body Mass Index (BMI) and examines their relation with Real Gross Domestic Product. From 1951 to 2010 the girls' height approximately increased by 6.2cm and weight by 6.8kg, while the boys' height increased by 12.2cm and weight by 17.3kg. Prior to 1991 mean BMI in girls was higher than in boys, but from 1991 on, the interrelation between the sexes has been opposite, possibly mirroring the cultural trends that started in mid-1970s and reflecting higher sensitivity of boys to the socioeconomic changes. In conclusion, the secular trend in body size over the investigated period reflects the positive economic trends interrupted by the war. The recent increase in BMI corresponds to the country's economic recovery and indicates the "nutrition transition". Copyright © 2013 Elsevier B.V. All rights reserved.

Sophie D Walsh

Full Text Available Then aims of the current study were 1 to provide cross-national estimates of the prevalence of physical fighting and weapon carrying among adolescents aged 11-15 years; (2 To examine the possible effects of physical fighting and weapon carrying on the occurrence of physical (medically treated injuries and emotional health outcomes (multiple health complaints among adolescents within the theoretical framework of Problem Behaviour Theory. 20,125 adolescents aged 11-15 in five countries (Belgium, Israel, USA, Canada, FYR Macedonia were surveyed via the 2006 Health Behaviour in School Aged Children survey. Prevalence was calculated for physical fighting and weapon carrying along with physical and emotional measures that potentially result from violence. Regression analyses were used to quantify associations between violence/weapon carrying and the potential health consequences within each country. Large variations in fighting and weapon carrying were observed across countries. Boys reported more frequent episodes of fighting/weapon carrying and medically attended injuries in every country, while girls reported more emotional symptoms. Although there were some notable variations in findings between different participating countries, increased weapon carrying and physical fighting were both independently and consistently associated with more frequent reports of the potential health outcomes. Adolescents engaging in fighting and weapon carrying are also at risk for physical and emotional health outcomes. Involvement in fighting and weapon carrying can be seen as part of a constellation of risk behaviours with obvious health implications. Our findings also highlight the importance of the cultural context when examining the nature of violent behaviour for adolescents.

Origins of the Tactical Nuclear Weapons Modernization Program: 1969-1979

Science.gov (United States)

Yaffe, Michael David

On December 12, 1979, the North Atlantic Treaty Organization decided to deploy new long-range theater nuclear forces, Pershing II and Ground-Launched Cruise Missiles. This marked the first major change in NATO's nuclear stockpile since the adoption of the flexible response strategy in 1967. The decision was controversial inasmuch as the Allies disagreed on the fundamental role of nuclear weapons in this strategy and, thereby, the types and number of weapons required for an effective deterrent posture. Europeans generally preferred long-range weapons capable of striking the Soviet Union and small conventional forces while Americans preferred shorter-range nuclear weapons and a stalwart conventional defense. Thus, the December decision is often described as purely politically motivated, in which the Americans reluctantly acquiesced to a European initiative for long-range weapons, prominently expressed by West German Chancellor Helmut Schmidt in 1977. Recently declassified US government documents reveal, however, that long-range missiles were part of a long-term comprehensive nuclear modernization program conceived in the Pentagon under Defense Secretary James Schlesinger during the period of 1973 through 1975, and presented to skeptical European elites who favored arms control negotiations over costly new deployments. This program was motivated as much by changes in the American national security culture as by an increase in the Soviet military threat to Europe. It was grounded on a clear military rationale: "that a feasible and affordable conventional defense is only possible if NATO has modern nuclear forces" that can effectively hold at risk Warsaw Pact ground and air forces throughout the depth of their employment from the inner-German border to the western military districts of the Soviet Union. When the new US administration in 1977 disagreed with the modernization plan and its rationale, opting instead for more conventional forces, the Allies in a reversal of

Simulated ICJ Judgment : Revisiting the Lawfulness of the Threat or Use of Nuclear Weapons

Directory of Open Access Journals (Sweden)

Winston P. Nagan

2012-04-01

Full Text Available The author prepared this simulated judgment at the request of Cadmus editors to demonstrate that there is ample ground for revisiting and revising the landmark 1996 advisory opinion of the ICJ on the legality of nuclear weapons. The ICJ failed to anticipate the proliferation of nuclear weapons, which expands the evolution of the concept of sovereignty, the potential cataclysmic impact of nuclear war on climate change, the multiplication of nuclear-weapon-free zones as evidence of a widespread rejection, mounting evidence regarding the physical and psychological harm, and unwillingness of the nuclear weapons states to fulfill their obligations under the NPT. This article challenges the notion that a few sovereign states should be the sole arbiters of international law and affirms the legitimate claim of the global community of protection from the existential threat posed by nuclear weapons. The use or threat of use undermines foundational values of the international legal system and the specific rules of self-defense and humanitarian law. The contribution seeks to give an accentuated role for the explicit use of the fundamental values of international legal order, in crafting an innovative methodology for the formulation of the judgment. The very existence of these weapons undermines the rights of all of humanity. The ICJ should be moved to categorically declare the use and possession of nuclear weapons a crime against humanity.

OIL AS POLITICAL WEAPON

International oil regime has changed in the last decades. In 1960, oil regime was a private oligopol which had links with governments main consuming countries. By then the price of a barrel of oil was two U.S. dollars and seven major transnational oil companies decided the amount of oil that will be produced. Meanwhile the world region with the largest oil exports were more strongly expressed nationalism and decolonization. Result, it was so in the late 60s in the region occur independent states. They have created an organization aim of this resource to their advantage - OPEC (Organization of Petroleum Exporting Countries. Thus since 1973 there have been changes in the international regime governing oil field, namely producing countries were fixed production rate and price. After this time the oil weapon has become increasingly important in the management of international relations. Oil influenced the great powers to Middle East conflicts that occurred in the last century, but their attitude about the emergence of new sources of oil outside OPEC. In the late 90's, Russia has become a major supplier of oil to the West.

Hazards of chemical weapons release during war: new perspectives.

Science.gov (United States)

Reutter, S

1999-01-01

The two major threat classes of chemical weapons are mustard gas and the nerve agents, and this has not changed in over 50 years. Both types are commonly called gases, but they are actually liquids that are not remarkably volatile. These agents were designed specifically to harm people by any route of exposure and to be effective at low doses. Mustard gas was used in World War I, and the nerve agents were developed shortly before, during, and after World War II. Our perception of the potency of chemical weapons has changed, as well as our concern over potential effects of prolonged exposures to low doses and potential target populations that include women and children. Many of the toxicologic studies and human toxicity estimates for both mustard and nerve agents were designed for the purpose of quickly developing maximal casualties in the least sensitive male soldier. The "toxicity" of the chemical weapons has not changed, but our perception of "toxicity" has. PMID:10585902

1990-01-01

Beginning with the first nuclear-weapons-related tests at the Nevada Test Site (NTS) in 1951, a radiation-related monitoring program was established to determine the levels and distribution of radionuclides released. Primary methods involved survey-meter-equipped field-monitoring teams and placement of film badges and air-sampling devices at fixed locations. Beginning in the mid-1950s, more stringent standards, the results of this monitoring program, and the results of related research programs led to increased engineering efforts to reduce local fallout. With passage of the National Environmental Policy Act and increased concern about possible effects of radiation exposure, environmental activities related to the NTS increased. There is now an extensive monitoring program at the NTS to assess radiological conditions resulting from past tests and from continued testing of nuclear-weapons devices. In populated areas near NTS, there is also a monitoring effort that relies on assistance from local communities. Other efforts include reconstruction of radiation doses received by offsite residents during the 1950s and 1960s, determination of the current inventory and distribution of radionuclides in surface soil, and studies of the movement of radionuclides in the desert ecosystem

Stability of transition to a world without nuclear weapons: Technical problems of verification

International Nuclear Information System (INIS)

Zhigalov, V.

1998-01-01

A serious psychological barrier to acceptance of the concept for achieving the nuclear-weapon-free world is fear of facing the prospect that one or more nations or extremist political groups might develop their own nuclear weapons. Actually this is a question of stability of the nuclear-weapon-free world. From this point of view the most effective system of verification is an absolute necessity. This system must ensure detection of so called undeclared nuclear activity at early stage. Scientists of Russian nuclear centers are working today on solving this problem. This paper is considered to be a comprehensive attempt to analyze the technical and organizational aspects of the problems of transition to a nuclear-weapons-free world, setting aside the difficulties of resolving purely political problems

Future of clip-on weapon sights: pros and cons from an applications perspective

US Domestic, International, allied Foreign National Warfighters and Para-Military First Responders (Police, SWAT, Special Operations, Law Enforcement, Government, Security and more) are put in harm's way all the time. To successfully complete their missions and return home safely are the primary goals of these professionals. Tactical product improvements that affect mission effectiveness and solider survivability are pivotal to understanding the past, present and future of Clip-On in-line weapon sights. Clip-On Weapon Sight (WS) technology was deemed an interim solution by the US Government for use until integrated and fused (day/night multi-sensor) Weapon Sights (WSs) were developed/fielded. Clip-On has now become the solution of choice by Users, Warriors, Soldiers and the US Government. SWaP-C (size, weight and power -cost) has been improved through progressive advances in Clip-On Image Intensified (I2), passive thermal, LL-CMOS and fused technology. Clip-On Weapon Sights are now no longer mounting position sensitive. Now they maintain aim point boresight, so they can be used for longer ranges with increased capabilities while utilizing the existing zeroed weapon and daysight optic. Active illuminated low-light level (both analog I2 and digital LL-CMOS) imaging is rightfully a real-world technology, proven to deliver daytime and low-light level identification confidence. Passive thermal imaging is also a real-world technology, proven to deliver daytime, nighttime and all-weather (including dirty battlefield) target detection confidence. Image processing detection algorithms with intelligent analytics provide documented promise to improve confidence by reducing Users, Warriors and Soldiers' work-loads and improving overall system engagement solution outcomes. In order to understand the future of Clip-On in-line weapon sights, addressing pros and cons, this paper starts with an overview of historical weapon sight applications, technologies and stakeholder decisions

Scope for nuclear weapon-free zone in central and eastern Europe

International Nuclear Information System (INIS)

Pande, Savita

1998-01-01

The idea of a Central Europe free of nuclear weapons has its roots, of course, in the end of the cold war and the break-up of the former Union. These historical developments created the necessary conditions for the Lisbon Protocol, the successful withdrawal of all nuclear weapons from Belarus, Ukraine, and Kazakhstan as well as these countries' accession to the Non-Proliferation Treaty. It is admitted that even before these steps had been achieved, Belarus had put forward the nuclear-free zone initiative at the United Nations General Assembly in 1991. Like all the other nuclear weapon-free zones, existing or potential, a proposal for such a zone entails that it be analysed in the context of its political environment, regional specificity as well as the role, and implications of the relevant outside powers. These include Warsaw Pact dissolution and its impact on control of tactical nuclear weapons as well as the North Atlantic Treaty Organisation (NATO's) expansion eastwards. It is equally important to look at the issue in the context of its history, or, in other words, the past attempts

WEAPONS COMPLEX OF RUSSIAN SERVING TATARS IN XV-XVII TH CENTURIES

Full Text Available The article considers the issue of the offensive and defensive armament of the serving Tatars of the Moscow state in the XV-XVIIth centuries, its research degree in the national historiography, the opportunities and prospects of its enhanced studying. The serving Tatars were one of the categories of the Moscow state nobility, which is reflected, first of all, in written sources. The weapons complex of Russian serving Tatars included minimal armour. European sources do not mention armour and helms or shield. But noble Tatars could have costly armour of many types that were used in that epoch by peoples of Eastern Europe and Middle East - Russians, Persians, Turks. The basic weapons of the serving Tatars were bows and arrows. In the close combat they were using sabres, and (rarely spears. The fire weapon was not used by the serving Tatars (or they used it very rarely and it was not characteristic for their weapons complex, because it was ineffective in their tactics. The serving Tatars were light mobile horse archers that preferred battles of long-distance.

Long-term retrievability and safeguards for immobilized weapons plutonium in geologic storage

Energy Technology Data Exchange (ETDEWEB)

Peterson, P.F. [Univ. of California, Berkeley, CA (United States)

1996-05-01

If plutonium is not ultimately used as an energy source, the quantity of excess weapons plutonium (w-Pu) that would go into a US repository will be small compared to the quantity of plutonium contained in the commercial spent fuel in the repository, and the US repository(ies) will likely be only one (or two) locations out of many around the world where commercial spent fuel will be stored. Therefore excess weapons plutonium creates a small perturbation to the long-term (over 200,000 yr) global safeguard requirements for spent fuel. There are details in the differences between spent fuel and immobilized w-Pu waste forms (i.e. chemical separation methods, utility for weapons, nuclear testing requirements), but these are sufficiently small to be unlikely to play a significant role in any US political decision to rebuild weapons inventories, or to change the long-term risks of theft by subnational groups.

If plutonium is not ultimately used as an energy source, the quantity of excess weapons plutonium (w-Pu) that would go into a US repository will be small compared to the quantity of plutonium contained in the commercial spent fuel in the repository, and the US repository(ies) will likely be only one (or two) locations out of many around the world where commercial spent fuel will be stored. Therefore excess weapons plutonium creates a small perturbation to the long-term (over 200,000 yr) global safeguard requirements for spent fuel. There are details in the differences between spent fuel and immobilized w-Pu waste forms (i.e. chemical separation methods, utility for weapons, nuclear testing requirements), but these are sufficiently small to be unlikely to play a significant role in any US political decision to rebuild weapons inventories, or to change the long-term risks of theft by subnational groups

The threat of nuclear terrorism: Nuclear weapons or other nuclear explosive devices

International Nuclear Information System (INIS)

Maerli, Morten Bremer

2001-01-01

Full text: Conventional weaponry and tactics are likely to remain the primary terrorist means for a definitive majority of sub-national groups. No non-state actors have ever deployed or used a nuclear device. However, recent developments in international terrorism may point in the direction of future terrorist uses of weapons of mass destruction, including nuclear devices. Some terrorist groups with a high international profile have showed disturbing interests in acquiring nuclear weapon capabilities. As the 'terrorist nuclear weapon standards' are likely to be lower than the strict requirements for traditional state nuclear weapons, technical barriers should not be considered sufficient to avoid future nuclear terrorist violence. Preventing any extremist group from achieving their goals of large-scale nuclear killing is likely best done by preventing the access to fissile materials through state compliances to rigorous standards of Material Protection, Control and Accountability (MPC and A).

Turkey's response to threats of weapons of mass destruction

OpenAIRE

Al, Guray.

2001-01-01

Unlike most of its NATO allies, Turkey did not emerge from the Cold War with enhanced security. The acquisition of weapons of mass destruction (WMD) and ballistic missiles by its neighbors in the Middle Eastâ Iran, Iraq and Syriaâ creates a serious security concern for Turkey. This thesis analyzes the numerous threats posed to Turkey by its neighborsα nuclear, chemical and biological weapons programs and their ballistic missiles. It evaluates Turkeyαs defense options to counter these thre...

Monitoring non-proliferation of weapons of mass destruction: Can regional CBMs play a role?

International Nuclear Information System (INIS)

Sood, R.

1994-01-01

The experience of regional Confidence Building Measures (CBM), has only limited applicability for tackling proliferation of weapons of mass destruction. Where the international norm has developed as in the case of biological and chemical weapons, through international disarmament treaties, regional initiatives can strengthen this norm. Where a norm is less well-founded, regional initiatives are not likely to succeed. Specifically, with regard to nuclear weapons, consensus on negotiations for a comprehensive test ban treaty and a convention for prohibition of production of fissile materials for nuclear weapons purposes and explosive devices is a positive development. Successful conclusion of these universal and verifiable treaties will go a long way to strengthening the international norm against proliferation. Two other measures are critical - a development of a non-use assurance and commencement of multilateral nuclear disarmament negotiations among all five nuclear weapon States. If the international community witnesses improvement in these areas, regional negotiations will be stimulated. Therefore, the primary focus should be on developing an international norm to eliminate weapons of mass destruction. Regional efforts will take their cue from these international norms and would result in CBMs that are consistent with the international norm

X-Ray Observations of High-Energy Pulsars: PSR B1951+32 and Geminga

Science.gov (United States)

Ho, Cheng

Observations at frequencies across a wide range of electromagnetic spectra are key to the understanding of the origin and mechanisms of high-energy emissions from pulsars. We propose to observe the high-energy pulsars PSR B1951+32 and Geminga with XTE. These two sources emit X-rays at low enough count rate that we can acquire high resolution timing and spectral data, allowing us to perform detailed analysis on the ground. Staring integration of 10 ksec for each source is requested. Data obtained in these observations, together with those from ROSAT, GRO and a planned project for optical counterpart study at Los Alamos, will provide crucial information to advance high-energy pulsar research.

Correcting environmental problems facing the nuclear weapons complex

International Nuclear Information System (INIS)

Rezendes, V.S.

1990-06-01

This report discusses DOE's efforts to correct the environmental problems facing the nuclear weapons complex. It focuses on three main points. First, the weapons complex faces a variety of serious and costly environmental problems. Second, during the past year, DOE has made some important changes to its organization that should help change its management focus from one that emphasizes materials production to one that more clearly focuses on environmental concerns. Third, because resolution of DOE's environmental problems will require considerable resources during a period of budgetary constraints, it is imperative that DOE have internal controls in place to ensure that resources are spent efficiently

Policy and technical issues for international safeguards in nuclear weapons states

International Nuclear Information System (INIS)

Markin, J.T.; Stanbro, W.D.

1994-01-01

Expansion of international safeguards into the military and commercial fuel cycles of the nuclear weapons states (NWS) -- the subject of previous proposals in international safeguards discussions and of studies in the safeguards literature -- has been given impetus by recent US government initiatives for safeguards on excess weapons materials and a verified fissile materials production cutoff. These proposals, if implemented, would have implications on the safeguards objectives, approaches, and technologies that are traditionally employed in international safeguards. This paper examines the modifications and innovations that might be required to the current international safeguards regime in meeting these proposed new roles. Although the examples given are in the context of the US materials and facilities, many of the conclusions are valid for other NWS. None of the statements in this paper represent official US position on policy for international safeguards in weapons states. Instead, the purpose is to identify policy and technical issues and to offer, where possible, options for their resolution. This paper limits consideration to the potential role of the IAEA in verifying these proposed initiatives for declared facilities, recognizing that there may also be a role for bilateral, multilateral, or regional verification regimes. Indeed, in some cases verification of weapons materials may be more appropriate for a bilateral arrangement. Because traditional IAEA safeguards may not be admissible for weapons materials, the concept of ''transparency'' is suggested as a less intrusive alternative providing some confidence that materials are as declared

Socio-economic impacts of major floods in Italy from 1951 to 2003

Lastoria, B.; Simonetti, M. R.; Casaioli, M.; Mariani, S.; Monacelli, G.

2006-03-01

Meteorological and hydrological monitoring and modeling, with particular regard for extreme hydrological events, represent important activities carried out by the Hydrological and Inland Waters Service of the Italian Agency for Environmental Protection and Technical Services (APAT). Recently, a study on the socio-economic effects of floods was published in the Italian Environmental Data Yearbook by APAT. It is based on processed data related to the major floods (i.e., events with at least a casualty or that have generated economic damages higher than 0.001% of the Gross Domestic Product) striking Italy between 1951 and 2003. Information was gathered from technical reports and/or databases belonging to APAT, Italian Regional Environmental Agencies (ARPAs), central and local authorities, research institutions and newspaper reports. These data are collected in tables reporting the number of flood events and of casualties and the amount of financial resources required for environmental restoration and/or for risk mitigation purposes. For year 2003, when APAT has begun a systematic monitoring of flood events in Italy, data concerning rainfall, number of persons involved, evacuation and urgent measures introduced to face the event (laws and acts) are also included. In this way, it was possible to realize a new database, in which flood events that caused the declaration of the state of emergency have been collected. Because of the difficulties in finding sufficiently reliable data for the period before the II World War, the collection of historical data started from 1951. During this period, about 50% of the flood events examined have caused at least 5 victims each, and about 10% more than 100; these data highlight the considerable social impact of flood events and suggest the importance of creating an integrated database to collect information about flood events involving all Europe. These two databases (the historical and updating archives) could be useful for taking

Rays as weapons

Vogel, H.

2007-01-01

Purpose: Ionizing radiation is being regarded as life threatening. Therefore, accidents in nuclear power plants are considered equal threatening as nuclear bomb explosions, and attacks with dirty bombs are thought as dangerous as nuclear weapon explosions. However, there are differences between a nuclear bomb explosion, the largest imaginable accident in a nuclear power plant, and an attack with a dirty bomb. It is intended to point them out. Method: The processes are described, which damage in a nuclear bomb explosion, in the largest imaginable accident in a nuclear power plant, and in an attack with a dirty bomb. Their effects are compared with each other, i.e. explosion, heat, shock wave (blast), ionizing radiation, and fallout. Results: In the center of the explosion of a nuclear bomb, the temperature rises to 100 Mio deg.C, this induces damaging heat radiation and shock wave. In the largest imaginable accident in a nuclear power plant and in the conventional explosion of a dirty bomb, the temperature may rise up to 3000 deg. C, heat radiation and blast are limited to a short distance. In nuclear power plants, explosions due to oxyhydrogen gas or steam may occur. In nuclear explosions the dispersed radioactive material (fall out) consists mainly of isotopes with short half-life, in nuclear power plants and in dirty bomb attacks with longer half-life. The amount of fall out is comparable in nuclear bomb explosions with that in the largest imaginable accident in a nuclear power plant, it is smaller in attacks with dirty bombs. An explosion in a nuclear power plant even in the largest imaginable accident is not a nuclear explosion. In Hiroshima and Nagasaki, there were 200,000 victims nearly all by heat and blast, some 300 died by ionizing radiation. In Chernobyl, there have been less than 100 victims due to ionizing radiation up till now. A dirty bomb kills possibly with the explosion of conventional explosive, the dispersed radioactive material may damage

Making Weapons for the Terracotta Army

Directory of Open Access Journals (Sweden)

Marcos Martinón-Torres

2011-10-01

Full Text Available The Terracotta Army of the First Emperor of China is one of the most emblematic archaeological sites in the world. Many questions remain about the logistics of technology, standardisation and labour organisation behind the creation of such a colossal construction in just a few decades over 2,000 years ago. An ongoing research project co-ordinated between the UCL Institute of Archaeology and the Emperor Qin Shihang's Terracotta Army Museum is beginning to address some of these questions. This paper outlines some results of the typological, metric, microscopic, chemical and spatial analyses of the 40,000 bronze weapons recovered with the Terracotta Warriors. Thanks to a holistic approach developed specifically for this project, it is possible to reveal remarkable aspects of the organisation of the Qin workforce in production cells, of the standardisation, efficiency and quality-control procedures employed, and of the sophisticated technical knowledge of the weapon-makers.

Nuclear power and nuclear weapons proliferation

International Nuclear Information System (INIS)

Anon.

1978-01-01

An appropriate non-proliferation treaty should not discriminate among the non-weapon states, but should seek a cooperative approach with all countries seeking nuclear power and willing to accept international safeguards. Near-term proliferation problems, represented by nations already on the threshold of weapon capability, should not be confused with the long-term problem of world-wide nuclear development. The first can be handled with incentives and disincentives imposed on specific countries, while the latter involves the distribution of plutonium on the basis of alternative fuel cycles. To retain world leadership, U.S. efforts along these lines should be to encourage a dialogue between suppliers and recipients and to coordinate the economic and security issues of its own non-proliferation and foreign policies. One option is a U.S. commitment to a multinational fuel storage and reprocessing facility. Technical evaluation and demonstration of alternative fuel cycles to reach an international consensus would be a parallel activity

Iran's nuclear program - for power generation or nuclear weapons?

International Nuclear Information System (INIS)

Kippe, Halvor

2008-11-01

This report addresses the development of a nuclear infrastructure in Iran, and assessments are made on the near-term potential this infrastructure might yield of either nuclear power or nuclear arms production. The most significant facilities are treated in a more elaborate fashion, as these are assumed to have key roles in either a true civilian programme, or in the prospect of weapons-grade fissile material production. The future potential capacity for the latter is calculated under certain presumptions, both in the case that Iran focuses its efforts on uranium-based nuclear weapons, and in the case that it should choose the plutonium path to nuclear weapons. All the conclusions and findings in this report are based on technological considerations. This means that social or political assessments have not prevailed, rather the picture of Iran's nuclear programme is drawn through descriptions and assessments of facilities and systems, and their role in the bigger context. Definite conclusions have not been made as to whether Iran's nuclear programme currently is aimed towards nuclear arms or nuclear power. The secrecy surrounding some of the most prominent nuclear sites together with more or less credible allegations of purely weapons-related activities in the past, make it hard not to conclude that Iran until the disclosures in 2002 made as great an effort as it could on its way on developing nuclear weapons covertly. The scope of today's nuclear programme seems, on the other hand, most likely to be in part to help relieve the ever-increasing need for energy, although considerable deficits to this strategy are identified, at the same time as the Iranian people are united in a giant, high-prestige project in defiance of massive international pressure. Adding to this is a much-feared ability to rapidly being able to redirect their nuclear efforts, and develop nuclear arms in perhaps as little as one year. This so-called break-out scenario, where Iran presumably

Homogenization of Tianjin monthly near-surface wind speed using RHtestsV4 for 1951-2014

Science.gov (United States)

Si, Peng; Luo, Chuanjun; Liang, Dongpo

2018-05-01

Historical Chinese surface meteorological records provided by the special fund for basic meteorological data from the National Meteorological Information Center (NMIC) were processed to produce accurate wind speed data. Monthly 2-min near-surface wind speeds from 13 observation stations in Tianjin covering 1951-2014 were homogenized using RHtestV4 combined with their metadata. Results indicate that 10 stations had significant breakpoints—77% of the Tianjin stations—suggesting that inhomogeneity was common in the Tianjin wind speed series. Instrument change accounted for most changes, based on the metadata, including changes in type and height, especially for the instrument type. Average positive quantile matching (QM) adjustments were more than negative adjustments at 10 stations; positive biases with a probability density of 0.2 or more were mainly concentrates in the range 0.2 m s-1 to 1.2 m s-1, while the corresponding negative biases were mainly in the range -0.1 to -1.2 m s-1. Here, changes in variances and trends in the monthly mean surface wind speed series at 10 stations before and after adjustment were compared. Climate characteristics of wind speed in Tianjin were more reasonably reflected by the adjusted data; inhomogeneity in wind speed series was largely corrected. Moreover, error analysis reveals that there was a high consistency between the two datasets here and that from the NMIC, with the latter as the reference. The adjusted monthly near-surface wind speed series shows a certain reliability for the period 1951-2014 in Tianjin.

A nuclear-weapons-free zone in Southeast Asia : problems and prospects

International Nuclear Information System (INIS)

Alagappa, M.

1987-01-01

Although the idea of a nuclear-weapons-free zone was already recognised in the Kuala Lumpur Declaration of 1971 and has been on the Asean agenda since the late 1970s as a component of the package to realise a Zone of Peace, Freedom and Neutrality in Southeast Asia, the formal initiative to make the region a nuclear-weapons-free zone is of relatively recent origin. The security benefits that are likely to accrue from declaring Southeast Asia nuclear-weapons-free are rather marginal. Benefits, as there are, are in the political and diplomatic realm where the proposed agreement can be used to influence the conduct of international relations which in turn may have the potential to modify the strategic environment of Southeast Asia

Antecedents of historical evolution of the uranium resources in the Cuyo region, between 1951 and 1968

Vergara Bai, A.A.

1992-01-01

The present article pretends to summarize the initial stage of the development of national uranium resources - focusing the labor done by the Escuela Superior de Ingenieria en Combustible of the Universidad Nacional de Cuyo - between the years 1951 and 1955 - feeling that it is necessary to describe the situations that were originated during the development of the uranium's mineral investigation. This was started by the Escuela Superior de Ingenieria en Combustible of U.N. de Cuyo, which facilitated the connection with CNEA, that had been created in 1950. This leaded to the economical help from CNEA until 1955, for the realization and execution of the programmed works. The national antecedents are described, taking into account the existence of deposits in this country. The historical evolution of the exloration of uranium in Cuyo is divided in three periods, which are described in detail in this work. First and foremost, the period that goes from 1951 to 1955 (U.N. de Cuyo and CNEA); then, the period that goes from 1956 to 1961 (CNEA) where the achievements obtained determined the new modern structures done by the CNEA in order to continue with the development of the uranium resources of the country. After this, the period that goes from 1961 to 1968 (activities and successes of the West Delegation) is pointed out. Finally, the evolution of the factories of uranium mineral treatment, i n the period between 1952 and 1990, is also described in this article. (Author) [es

Options for the destruction of chemical weapons and management of the associated risks.

Science.gov (United States)

Manley, Ron G

2006-09-01

The destruction of chemical weapons is a hazardous operation. The degree of hazard posed, however, is not uniform and is dependent on the specific chemical agent and the configuration of the weapon or bulk storage vessel in which it is contained. For example, a highly volatile nerve agent in an explosively configured munition, such as a rocket, poses a very different hazard from that of a bulk storage container of viscous mustard gas. Equally the handling of recovered, often highly corroded, World War (WW)I or WWII chemical munitions will pose a very different hazard from that associated with dealing with modern chemical weapons stored under the appropriate conditions. Over the years, a number of technologies have been developed for the destruction of chemical weapons. Each has its advantages and disadvantages. None of them provide a universal solution to the problem. When assessing options for the destruction of these weapons and the management of the associated risks, therefore, it is important to give due consideration and weight to these differences. To ensure that the destruction technology selected takes due account of them and that the resulting overall risk assessment accurately reflects the actual risks involved.

Nuclear weapons proliferation as a world order problem

International Nuclear Information System (INIS)

Falk, R.

1977-01-01

World-order concerns have intensified recently in light of mounting evidence that a weapons capability will soon be within easy reach of more and more governments and of certain nongovernmental groupings as well. One reliable source estimates that by 1985 as many as fifty countries could ''produce enough plutonium each year for at least several dozen nuclear explosives.'' In an even more immediate sense, ''economic competition among nuclear suppliers today could soon lead to a world in which twenty or more nations are but a few months from a nuclear weapons force.'' Three developments have created this ''world order'' sense of concern: (1) increased pace of civilian nuclear power deployment globally as a consequence of rising oil prices, unreliability of oil supplies, and reality of dwindling oil reserves in any case; (2) actuality of India's nuclear explosion in May 1974 which demonstrated vividly how any state that pursues a ''civilian'' program can also develop its own weapons capability; and (3) the intensification of competition for international nuclear sales which makes it increasingly evident that nonproliferation goals are no longer compatible with the pursuit of national commercial advantage; essentially, this reality has emerged from a break in the American monopoly over civilian nuclear technology and the willingness of French and German suppliers to provide all elements of the nuclear fuel cycle, including enrichment and reprocessing facilities,to any nation that feels it can afford to buy them; the German-Brazilian deal (worth at least $4 billion) has proven to be the equivalent in the commercial realm of India's ''peaceful'' nuclear explosion. Such developments disclose the alarming prospect that easier access to nuclear technology will make it relatively simple and thus more likely for a beleaguered government or a desperate political actor of any sort to acquire and possibly use nuclear weapons

The United Nations Global Counter-Terrorism Strategy was adopted by the UN General Assembly in September 2006. Preventing and responding to attacks using WMD were identified amongst the key areas of activities covered by the strategy. The Secretary-General's mechanism to carry out prompt investigations in response to allegations brought to his attention concerning the possible use of chemical and bacteriological (biological) and toxin weapons was developed in the late 1980s. Triggered by a request from any member State, the Secretary-General is authorized to launch an investigation including dispatching a fact-finding team to the site of the alleged incident(s) and to report to all UN Member States. This is to ascertain in an objective and scientific manner facts of alleged violations of the 1925 Geneva Protocol, which bans the use of chemical and biological weapons. Member States encouraged the Secretary-General in September 2006 to update the roster of experts and laboratories, as well as the technical guidelines and procedures, available to him for the timely and efficient investigation of alleged use. The roster of experts and laboratories and the guidelines and procedures constitute the key elements of the special mechanism available to the Secretary-General for investigation of reports by Member States of alleged use of chemical, biological and toxin weapons.

The positive portrayal of violence and weapon carrying in televised music videos is thought to have a considerable influence on the normative expectations of adolescents about these behaviors. To perform a content analysis of the depictions of violence and weapon carrying in music videos, including 5 genres of music (rock, rap, adult contemporary, rhythm and blues, and country), from 4 television networks and to analyze the degree of sexuality or eroticism portrayed in each video and its association with violence and weapon carrying, as an indicator of the desirability of violent behaviors. Five hundred eighteen videos were recorded during randomly selected days and times of the day from the Music Television, Video Hits One, Black Entertainment Television, and Country Music Television networks. Four female and 4 male observers aged 17 to 24 years were trained to use a standardized content analysis instrument. Interobserver reliability testing resulted in a mean (+/- SD) percentage agreement of 89.25% +/- 7.10% and a mean (+/- SD) kappa of 0.73 +/- 0.20. All videos were observed by rotating 2-person, male-female teams that were required to reach agreement on each behavior that was scored. Music genre and network differences in behaviors were analyzed with chi 2 tests. A higher percentage (22.4%) of Music Television videos portrayed overt violence than Video Hits One (11.8%), Country Music Television (11.8%), and Black Entertainment Television (11.5%) videos (P = .02).

Chemical weapons dumped into the ocean for disposal in the twentieth century pose a continuing environmental and human health risk. In this review we discuss locations, quantity, and types of sea-dumped chemical weapons, related environmental concerns, and human encounters with sea-dumped chemical weapons. We utilized the Ovid (http://ovidsp.tx.ovid.com) and PubMed (http://www.pubmed.org) search engines to perform MEDLINE searches for the terms 'sea-dumped chemical weapons', 'chemical warfare agents', and 'chemical munitions'. The searches returned 5863 articles. Irrelevant and non-English articles were excluded. A review of the references for these articles yielded additional relevant sources, with a total of 64 peer-reviewed articles cited in this paper. History and geography of chemical weapons dumping at sea: Hundreds of thousands of tons of chemical munitions were disposed off at sea following World War II. European, Russian, Japanese, and United States coasts are the areas most affected worldwide. Several areas in the Baltic and North Seas suffered concentrated large levels of dumping, and these appear to be the world's most studied chemical warfare agent marine dumping areas. Chemical warfare agents: Sulfur mustard, Lewisite, and the nerve agents appear to be the chemical warfare agents most frequently disposed off at sea. Multiple other type of agents including organoarsenicals, blood agents, choking agents, and lacrimators were dumped at sea, although in lesser volumes. Environmental concerns: Numerous geohydrologic variables contribute to the rate of release of chemical agents from their original casings, leading to difficult and inexact modeling of risk of release into seawater. Sulfur mustard and the organoarsenicals are the most environmentally persistent dumped chemical agents. Sulfur mustard in particular has a propensity to form a solid or semi-solid lump with a polymer coating of breakdown products, and can persist in this state on the ocean floor

Plutonium: key issue in nuclear disarmament and non-proliferation of nuclear weapons

International Nuclear Information System (INIS)

Yoshisaki, M.B.

1993-01-01

The technical report is a 1993 update on weapons-grade plutonium, a key issue in nuclear disarmament. Its vital significance would again be discussed during the fifth and the last Review Conference on the Non-Proliferation Treaty (NPT) for Nuclear Weapons which would end in 1995. Member States shall decide whether an indefinite or conditional extension of NPT is necessary for world peace and international security. Two Non-NPT States, Russia and U.S.A. are in the forefront working for the reduction of nuclear weapons through nuclear disarmament. Their major effort is focused on the implementation of the Strategic Arms Reduction Treaty I and II or START I and II for world peace. The eventual implementation of START I and II would lead to the dismantling of plutonium from nuclear warheads proposed to be eliminated by both countries. This report gives three technical options to be derived from nuclear disarmament issues for the non-proliferation of nuclear weapons: (a) indefinite storage - there is no guarantee that these will not be used in the future (b) disposal as wastes - possible only in principle, because of lack of experience in mixing plutonium with high level wastes, and (c) source of energy - best option in managing stored weapons materials, because it satisfies non-proliferation objectives. It means fuel for energy in Light Water Reactors (LWR) or Fast Breeder Reactors (FBR). (author). 8 refs

Chinese perceptions of the utility of nuclear weapons. Prospects and potential problems in disarmament

Energy Technology Data Exchange (ETDEWEB)

2010-07-01

The Obama administration is putting nuclear disarmament back on the agenda. In a major speech in Prague in April 2009, he envisioned a world free of nuclear weapons and called on nations to work toward that end. Reversing years of setbacks and stagnation, Washington and Moscow agreed on renewing negotiation on extending the START I Treaty last year and concluded the New START treaty in March 2010. The 2010 Nuclear Posture Review indicates a shift in U.S. nuclear doctrine in that Washington pledges not to use nuclear weapons against non-nuclear weapons states that abide by the Nuclear Nonproliferation Treaty. The prospects of nuclear disarmament look much promising as the momentum generated could also exert pressure on the second-tier nuclear-weapon States: Britain, France, and China. Beijing's responses to these developments have been favorable, viewing them as positive contribution to international nuclear disarmament and nonproliferation. In particular China endorses President Obama's call for securing global nuclear materials and safeguarding vulnerable nuclear facilities to prevent nuclear terrorism. However, Chinese perspectives and policies on important international nuclear arms control and disarmament, and on the role of nuclear weapons and nuclear deterrence remain largely declaratory and less specific on its own commitments and participation. Chinese analyses, at the same time, point out the difficulties ahead on the road toward a nuclear weapons free world. Indeed, rhetoric notwithstanding, Beijing continues to modernize its nuclear arsenal to develop a secure and reliable second-strike deterrence capability. This paper takes a careful look at China's perceptions of the role of nuclear weapons in its national security policy and defense posture. This is important because China is perceived to be the only country among the five original nuclear-weapon States that is actually expanding its nuclear arsenal, as indicated by the recent

Risk of beryllium sensitization in a low-exposed former nuclear weapons cohort from the Cold War era.

Mikulski, Marek A; Leonard, Stephanie A; Sanderson, Wayne T; Hartley, Patrick G; Sprince, Nancy L; Fuortes, Laurence J

2011-03-01

The nuclear weapons industry has long been known as a source of beryllium exposure. A total of 1,004 former workers from a nuclear weapons assembly site in the Midwest were screened for sensitization to beryllium (BeS). The screenings were part of the Department of Energy (DOE) Former Worker Program established in 1996. Twenty-three (2.3%) workers were found sensitized to beryllium and this prevalence was comparable to other DOE sites. Occasional, direct exposure to beryllium through machining and grinding of copper-beryllium (Cu-Be) 2% alloy tools was found to increase the risk of sensitization compared to background exposure (OR = 3.83; 95% CI: 1.04-14.03) with a statistically significant trend (P = 0.03) revealing that particular jobs are associated with sensitization. Exposure potential in this study was estimated based on job titles and not personal exposure information. These results confirm the need to screen workers using beryllium alloy tools in other industries and for consideration of altering work practices. Copyright © 2010 Wiley-Liss, Inc.

The bioscience revolution & the biological weapons threat: levers & interventions

2009-02-01

Full Text Available Abstract In December 2008, the US Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism, released a report, World At Risk. The Report points to the fact that, not only is the use of a weapon of mass destruction in a terrorist attack before the end of 2013, more likely than not, but also to the fact that terrorists are more likely to be able to obtain and use biological weapons than nuclear. This paper examines the recommendations of the report in the context of the historic and geopolitical changes, in particular globalization. The authors highlight the "dual-use" dilemma, as described in the report, as the paradoxical use of technology developed for the benefit of mankind being used for sinister purposes. The mitigation of such a threat lies in broad stakeholder involvement and cooperation, including non-state actors, governments and the bio-tech industry itself. The importance of vigilance measures within the life science community is emphasized and, the authors propose, could include a web-based didactic course in bioterrorism and weapons of mass destruction identification. The site could outline safety protocols, have detailed disaster management tutorials, and could be specifically tailored for different subsets of industry and health professionals. The paper concludes with an endorsement of a multi-pronged approach including strong international guidelines and intelligence cooperation and preparatory measures such as the wide-spread use of detection systems as well as diagnostic decision support systems for bioterrorism detection at the local level.

Interim storage of dismantled nuclear weapon components at the U.S. Department of Energy Pantex Plant

International Nuclear Information System (INIS)

Guidice, S.J.; Inlow, R.O.

1995-01-01

Following the events of 1989 and the subsequent cessation of production of new nuclear weapons by the US, the mission of the Department of Energy (DOE) Nuclear Weapons Complex has shifted from production to dismantlement of retired weapons. The sole site in the US for accomplishing the dismantlement mission is the DOE Pantex Plant near Amarillo, Texas. Pending a national decision on the ultimate storage and disposition of nuclear components form the dismantled weapons, the storage magazines within the Pantex Plant are serving as the interim storage site for pits--the weapon plutonium-bearing component. The DOE has stipulated that Pantex will provide storage for up to 12,000 pits pending a Record of Decision on a comprehensive site-wide Environmental Impact Statement in November 1996

Public involvement in environmental, safety and health issues at the DOE Nuclear Weapons Complex

International Nuclear Information System (INIS)

Taylor, Laura L.; Morgan, Robert P.

1992-01-01

The state of public involvement in environmental, safety, and health issues at the DOE Nuclear Weapons Complex is assessed through identification of existing opportunities for public involvement and through interviews with representatives of ten local citizen groups active in these issues at weapons facilities in their communities. A framework for analyzing existing means of public involvement is developed. On the whole, opportunities for public involvement are inadequate. Provisions for public involvement are lacking in several key stages of the decision-making process. Consequently, adversarial means of public involvement have generally been more effective than cooperative means in motivating change in the Weapons Complex. Citizen advisory boards, both on the local and national level, may provide a means of improving public involvement in Weapons Complex issues. (author)

Manhattan Project redux: Canada and the first atomic weapons

Only three nuclear weapons produced by the Manhattan Project (MP) were used during World War II: Trinity Test, New Mexico on 16 July 1945, Hiroshima, Japan, on 6 August 1945, and Nagasaki, Japan, on 9 August 1945. Several sources and authors, including EM and RL (1967), Stacey (1970), Sanger (1981), and Buckley (2000), have written that it is unlikely that any Canadian uranium was used in the atomic weapons that ended WW II. These sources offer no detailed justification for their conclusion, nevertheless, after analysis of data contained in numerous sources, this article reaches a similar conclusion. (author)

Is there any future for nuclear weapons?

International Nuclear Information System (INIS)

Heisbourg, F.

2011-01-01

Nuclear weapons occupy a paradoxal place both in the collective imagination and in the historical reality: on the one hand everybody dreads the apocalypse horror, and on the other hand, dissuasion appears as an unchanging and quite comfortable situation. However, the world has become multipolar in this domain as well. The geopolitical map is reconstructing. Doctrinal revisions, initiatives against nuclear weapons proliferation, and nuclear disarmament measures are now on the agenda. The best foreign and French experts examine for the first time the consequences of these evolutions. They analyse in particular the split up risks and the potential consequences of a nuclear conflict in regions where atomic arms have become a key-component of the strategic landscape: Middle-Est, Far-East, Southern Asia. The choices France and its allies will have to face are examined as well. (J.S.)

In this book, GAO characterizes DOE's January 1991 Nuclear Weapons Complex Reconfiguration Study as a starting point for reaching agreement on solutions to many of the complex's safety and environmental problems. Key decisions still need to be made about the size of the complex, where to relocate plutonium operations, what technologies to use for new tritium production, and what to do with excess plutonium. The total cost for reconfiguring and modernizing the complex is still uncertain, and some management issues remain unresolved. Congress faces a difficult task in making test decisions given the conflicting demands for scarce resources in a time of growing budget deficits and war in the Persian Gulf

Pole-weapons in the Sagas of Icelanders: a comparison of literary and archaeological sources

Directory of Open Access Journals (Sweden)

Orkisz Jan H.

2016-04-01

Full Text Available The Icelandic sagas are a major source of information on the Vikings and their fighting prowess. In these stories, several mysterious pole-weapons appear, which are often called “halberds”, for lack of a better word. In order to better identify what these weapons could have been, and to provide a better understanding of how the sagas relate to the Viking-age events they describe, we confront textual and archaeological evidence for several of these weapons (the höggspjót, the atgeirr, the kesja, the krókspjót, the bryntroll and the fleinn, keeping in mind the contextualisation of their appearances in sagas. The description of the use of each weapon allows to pick several candidates likely to correspond to the studied word. Without a perfect knowledge of what context the authors of the sagas wanted to describe, it appears to be impossible to give a final answer. However, we show that some specific types of spears are good candidates for some of the studied weapons.

Low enrichment of uranium in the light of the nuclear weapon problem

International Nuclear Information System (INIS)

Barstad, G.

1979-09-01

A difficult problem in the immediate future will be to direct civil nuclear technology in such a way that the ability to produce nuclear weapons by additional countries is prevented. There are two main problems. First, enrichment plants can be used to produce high enriched uranium, which can be used in nuclear weapons, as well as low enriched reactor fuel. Second, plutonium produced during reactor operation can be used as nuclear weapon material, as well as for nuclear fuel. The problem discussed here is particularly the development of an enrichment process which is economic for low enriched reactor fuel, but which may not easily be adapted to produce high enriched uranium.

1990-01-01

Timing observations of PSR 1951+32, the 39.5 ms pulsar found in the CTB 80 supernova remnant, have detected a spin-up in the rotation rate of the neutron star. The fractional change in the rotational frequency of 2.1 x 10 to the -9th was accompanied by a fractional change in the frequency derivative of -0.00019 which has persisted for 1 yr after the event. Updated VLA astrometric observations of the pulsar are presented. Dispersion measure variations have been measured between 430 MHz and 1400 MHz at the level of 0.02 pc/cu cm. Together, dispersion measure fluctuations and diffractive scintillations indicate a power-law electron density turbulence spectrum on scales sizes between 10 to the 9th and 10 to the 14th cm that may be relevant to cosmic-ray propagation. 34 refs

Possible steps on the road to a nuclear-weapon-free Europe: The plan for the denuclearization of Europe

International Nuclear Information System (INIS)

Gorbulin, V.; Shevtsov, A.

1998-01-01

In connection with the plans for NATO expansion in Eastern Europe, the issue of defining the role of nuclear weapons in Europe has become exceptionally acute. A 'hidden' nuclear proliferation in Europe arising from NATO expansion would unambiguously conflict with the spirit of the Non-proliferation Treaty (NPT). At the same time the volume of possible military tasks of battlefield nuclear weapons has drastically shrunk in the pos-Cold War period. As a solution to the problems that have arisen, three steps to a nuclear-weapon-free Europe are proposed: obtain commitments from the USA, Great Britain and France not to expand the base areas of battlefield nuclear weapons; create a nuclear-weapon-free zone in Central and East Europe; eliminate battlefield nuclear weapons in Europe

Microstructures of reduced-activation F82H (8Cr-2W-0.2V-0.04Ta) and the F82H steels doped with 10 B, irradiated at 250 and 300 C to 3 and 57 dpa in the High Flux Isotope Reactor (HFIR), were examined by TEM. In the F82H irradiated at 250 C to 3 dpa, dislocation loops, small unidentified defect clusters with a high number density, and a few MC precipitates were observed in the matrix. The defect microstructure after 300 C irradiation to 57 dpa is dominated by the loops, and the number density of loops was lower than that of the F82H- 10 B steel. Cavities were observed in the F82H- 10 B steels, but the swelling value is insignificant. Small particles of M 6 C formed on the M 23 C 6 carbides that were present in both steels before the irradiation at 300 C to 57 dpa. A low number density of MC precipitate particles formed in the matrix during irradiation at 300 C to 57 dpa
