Politics and Scientific Expertise: Scientists, Risk Perception, and Nuclear Waste Policy

To study the homogeneity and influences on scientists'perspectives of environmental risks, we have examined similarities and differences in risk perceptions, particularly regarding nuclear wastes, and policy preferences among 1011 scientists and engineers. We found significant differences ( p 0.05)in the patterns of beliefs among scientists from different fields of research. In contrast to physicists, chemists, and engineers, life scientists tend to: (a)perceive the greatest risks from nuclear energy and nuclear waste management; (b)perceive higher levels of overall environmental risk; (c)strongly oppose imposing risks on unconsenting individuals; and (d)prefer stronger requirements for environmental management. On some issues related to priorities among public problems and calls for government action, there are significant variations among life scientists or physical scientists. We also found that–independently of field of research–perceptions of risk and its correlates are significantly associated with the type of institution in which the scientist is employed. Scientists in universities or state and local governments tend to see the risks of nuclear energy and wastes as greater than scientists who work as business consultants, for federal organizations, or for private research laboratories. Significant differences also are found in priority given to environmental risks, the perceived proximity of environmental disaster, willingness to impose risks on an unconsenting population, and the necessity of accepting risks and sacrifices.

Scheduling Updates of Probabilistic Risk Assessments: The Arkansas Nuclear One-Unit 1 Experience

This paper presents the results of a study that identified how often a probabilistic risk assessment (PRA)should be updated to accommodate the changes that take place at nuclear power plants. Based on a 7-year analysis of design and procedural changes at one plant, we consider 5 years to be the maximum interval for updating PRAs. This conclusion is preliminary because it is based on the review of changes that occurred at a single plant, and it addresses only PRAs that involve a Level 1 analysis (i.e., a PRA including calculation of core damage frequency only). Nevertheless, this conclusion indicates that maintaining a useful PRA requires periodic updating efforts. However, the need for this periodic update stems only partly from the number of changes that can be expected to take place at nuclear power plants–changes that individually have only a moderate to minor impact on the PRA, but whose combined impact is substantial and necessitates a PRA update. Additionally, a comparison of two generations of PRAs performed about 5 years apart indicates that PRAs must be periodically updated to reflect the evolution of PRA methods. The most desirable updating interval depends on these two technical considerations as well as the cost of updating the PRA. (Cost considerations, however, were beyond the scope of this study.)     

Changes in the Factors Influencing Public Acceptance of Nuclear Power Generation in Japan Since the 2011 Fukushima Daiichi Nuclear Disaster

Public support for nuclear power generation has decreased in Japan since the Fukushima Daiichi nuclear accident in March 2011. This study examines how the factors influencing public acceptance of nuclear power changed after this event. The influence factors examined are perceived benefit, perceived risk, trust in the managing bodies, and pro‐environmental orientation (i.e., new ecological paradigm). This study is based on cross‐sectional data collected from two online nationwide surveys: one conducted in November 2009, before the nuclear accident, and the other in October 2011, after the accident. This study's target respondents were residents of Aomori, Miyagi, and Fukushima prefectures in the Tohoku region of Japan, as these areas were the epicenters of the Great East Japan Earthquake and the locations of nuclear power stations. After the accident, trust in the managing bodies was found to have a stronger influence on perceived risk, and pro‐environmental orientation was found to have a stronger influence on trust in the managing bodies; however, perceived benefit had a weaker positive influence on public acceptance. We also discuss the theoretical and practical implications of these findings.     

Disposable waste,lands and bodies under Canada’s gendered nuclear colonialism

ABSTRACT

Nuclear colonialism, or the exploitation of Indigenous lands and peoples to sustain the nuclear fuel cycle from uranium mining and refining to nuclear energy and weapons production and the dumping of the resulting nuclear waste, occurs in many parts of the world and has generated considerable protest. This article focuses on a contemporary and ongoing case of nuclear colonialism in Canada: attempts to site two national deep geological repositories (DGRs) for nuclear waste on traditional First Nations land in Southwestern Ontario near the world’s largest operational nuclear power plant. Through histories of the rise of nuclear power and nuclear waste policy-making and their relationship to settler colonialism in Canada, as well as actions taken by the Saugeen Ojibway Nation (SON) and white settler anti-nuclear waste movements, the article explores how gender is at work in nuclear colonialism and anti-nuclear waste struggles. Gender is explored here in terms of the patriarchal nuclear imperative, the appropriation of Aboriginal land through undermining Aboriginal women’s status and the problematic relationship between First Nations and white settler women-led movements in resistance to nuclear waste burial from a feminist decolonial perspective     

阿拉伯国家转型及其走势

埃及军方推翻穆兄会政权,局势仍难以稳定;叙利亚化武危机化解,但政治解决步履艰难;巴、以重启和谈,取得突破仍困难重重;美、伊关系松动,伊核谈判取得阶段性成果;美国在中东地区的主导能力下降;阿拉伯国家转型之路漫长而艰难;伊斯兰势力崛起受挫。     

冷战后美国中东战略的调整与伊朗核问题

新一届美国政府成立后,其对伊朗核问题的立场成为国际社会广泛关注的热点问题。伊朗核问题解决的方式,主要取决于美伊双方,但在全球化的今天,美国和伊朗走向直接对抗甚至爆发战争的可能性越来越小,双方更可能以全方位外交谈判的方式来解决美伊之间的矛盾。     

Monitoring the complexities: Nuclear power and public opinion

Interaction between organizations and stakeholders today takes place on virtual and physical ‘issue arenas’. This study examined opinions on nuclear power and asked who are the players discussing nuclear power in Finland? Through content analysis, surveys and interviews, the study concluded that politicians, power companies and regulators were the ones with voice, as NGOs and citizens were hardly heard. The paper suggests the future role of PR practitioners to be to find the right issue arenas and facilitate corporate voice and reputation on those arenas.
