\"The inside story of how nuclear energy--long considered scary, controversial, and even apocalyptic--has become the hot topic of the climate debate, and perhaps a vital power source of the future.\"--Amazon.

Due to the increasing population and the growing need for providing energy from a clean and non-fossil resource, there is an increasing interest in nuclear energy all over the world. As a fact, environmental capability evaluation should be considered for establishment of new nuclear power plants, not only to increase the safety against environmental risks, but also to achieve sustainable development. This study focuses on environmental capability evaluation for the nuclear power plant site selection in the coastal area of Gilan Province (Sahar Khiz). Considering the natural potentials and limitations of the area, the existing laws and regulations set by the International Atomic Energy Agency, United States Nuclear Regulatory Commission and Department of Environment, ecological and socioeconomic criteria were the main object of this study. At first, the Boolean logic method was used to prepare layered maps and identify selected zones, using geographical information system (GIS) and the “AND” operator. Then, the fuzzy logic method based on weighted linear combination (WLC) was applied for site selection of the new nuclear power plant. Four main criteria (physical, biological, social and economic) and 15 sub-criteria have been chosen for site selection process, from all selected criteria and sub-criteria. After preparing the raster maps of the ecological and socioeconomic sub-criteria, the fuzzy logic was used to standardize data layers between zero and one. Then, a relative weight was assigned to each criterion using Expert Choice software and the analytical hierarchy process (AHP) method. At the end, to combine all sub-criteria, fuzzy logic method based on WLC was used in GIS environment, and the final map of environmental capability was prepared. The results of this study were compared to the results using the Boolean logic method, showing high coverage between the two methodologies, while the fuzzy logic method based on WLC combined with the AHP method had more flexibility and more accuracy comparing with the Boolean logic method.

The US is laying plans that could lead to recycling commercial nuclear waste into fuel for the first time in almost 30 years, but critics worry that such a boost for nuclear power could undermine global efforts to stop the spread of nuclear weapons. The Department of Energy's (DOE's) new budget, signed by Pres George W. Bush last month, contains $50 million toward a goal of beginning construction on an engineering-scale reprocessing plant by 2010.

In recent years, a great deal has been written and discussed about the need for the US to develop sustainable sources of energy that do not pollute the air or water. Although the concept of sustainable energy is a hot-button issue today, attempts to develop such technologies are not new. In 1943, physicist Leo Szilard suggested it might be possible to construct a nuclear reactor that would create or breed fuel, producing an inexhaustible supply of energy. The concept became so compelling that the federal government would vigorously pursue it for the next forty years, with the ultimate goal of having the nation's electricity generated largely by breeder reactors. The purpose of this article is to briefly chronicle major developments in the history of the breeder reactor in the US. It is a history of peaks and valleys, where the federal government attempted to rapidly develop a technology based on what turned out to be a set of erroneous assumptions.

The worldwide expansion of nuclear energy has been accompanied by concerns about nuclear weapons proliferation. If sited in states that do not possess nuclear weapons technology, some civilian nuclear technologies could provide a route for states or other organizations to acquire nuclear weapons. Metrics for assessing the resistance of a nuclear technology to diversion for non-peaceful uses-proliferation resistance-have been developed, but at present there is no clear consensus on whether and how these metrics are useful to policy decision makers. In 2011, the U.S. Department of Energy asked the National Academies to convene a public workshop addressing the capability of current and potential methodologies for assessing host state proliferation risk and resistance to meet the needs of decision makers. Proliferation Risk in Nuclear Fuel Cycles is a summary of presentations and discussions that transpired at the workshop-held on August 1-2, 2011-prepared by a designated rapporteur following the workshop. It does not provide findings and recommendations or represent a consensus reached by the symposium participants or the workshop planning committee. However, several themes emerged through the workshop: nonproliferation and new technologies, separate policy and technical cultures, value of proliferation resistance analysis, usefulness of social science approaches. The workshop was organized as part of a larger project undertaken by the NRC, the next phase of which (following the workshop) will be a consensus study on improving the assessment of proliferation risks associated with nuclear fuel cycles. This study will culminate in a report prepared by a committee of experts with expertise in risk assessment and communication, proliferation metrics and research, nuclear fuel cycle facility design and engineering, international nuclear nonproliferation and national security policy, and nuclear weapons design. This report is planned for completion in the spring of 2013.

Toxicologists are often called upon to assist in environmental, industrial, occupational and public health assessments. Accordingly, medical toxicologists may find it prudent to be aware of applicable federal toxicological regulations and reporting requirements and of the roles of relevant federal agencies. These regulations are numerous, complex, and have evolved and expanded over time, making it difficult for toxicologists to sustain a current knowledge base. This article reviews the pertinent federal toxicological reporting requirements with regards to the Toxic Substances Control Act (TSCA), the Atomic Energy Act (AEA), the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the Resource Conservation and Recovery Act (RCRA), the Clean Air Act, the Clean Water Act, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Emergency Planning and Community Right to Know Act (EPCRA), the Occupational Safety and Health Act, the Department of Transportation, and information about the National Response Center. We reference internet-based government resources and offer direct links to applicable websites in an attempt to offer rapid and current sources of practical information. The format of the article is a series of hypothetical scenarios followed by commentary. Discussions of the Safe Drinking Water Act and the Food, Drug, and Cosmetic Act and the Dietary Supplement Health and Education Act are beyond the scope of this paper. For those desiring a more in depth discussion of the relevant federal environmental laws and statutes, and applicable case law, the reader is directed to resources such as the Environmental Law Handbook, the websites of individual laws found at www.epa.gov and the decisions of individual courts of appeal. It is our hope that this article provides not only useful practical information for the practicing toxicologist, but also serves as a key reference for Medical Toxicology core content on environmental laws and regulations.
