A new approach is introduced for evaluating strategies for the safe disposal of high-level nuclear waste. Five strategies are considered, and by means of the effective method of 'analytic hierarchy process' these strategies are prioritized with respect to a set of tangible and intangible criteria. The results are compared with criteria adopted by the United States Department of Energy. The approach demonstrates that, when good judgments are used, one can solve complex decision problems in a simple way and make a rational decision in a short time.

Prominent figures believe that expert judgment must play a decisive role in implementing the NWPAA. An examination of this method is provided. Resolution of difficulties inherent to expert judgment reveals the adoption of equally problematic epistemological assumptions. A fresh approach is offered. (Original abstract-amended)

Prominent figures believe that expert judgment must play a decisive role in implementing the NWPAA. A critical, philosophical examination of this method is provided. Resolution of difficulties inherent to expert judgment reveals the adoption of equally problematic epistemological assumptions. A fresh approach which rejects the dichotomies bred by the controversy over the status of expert judgment is offered.

Germany is phasing-out the utilization of nuclear energy until 2022. Currently, nine light water reactors of originally nineteen are still connected to the grid. All power plants generate high-level nuclear waste like spent uranium or mixed uranium-plutonium dioxide fuel which has to be properly managed. Moreover, vitrified high-level waste containing minor actinides, fission products, and traces of plutonium reprocessing loses produced by reprocessing facilities has to be disposed of. In the paper, the assessments of German spent fuel legacy (heavy metal content) and the nuclide composition of this inventory have been done. The methodology used applies advanced nuclear fuel cycle simulation techniques in order to reproduce the operation of the German nuclear power plants from 1969 till 2022. NFCSim code developed by LANL was adopted for this purpose. It was estimated that ~10,300 tonnes of unreprocessed nuclear spent fuel will be generated until the shut-down of the ultimate German reactor. This inventory will contain ~131 tonnes of plutonium, ~21 tonnes of minor actinides, and 440 tonnes of fission products. Apart from this, ca.215 tonnes of vitrified HLW will be present. As fission products and transuranium elements remain radioactive from 104to 106years, the characteristics of spent fuel legacy over this period are estimated, and their impacts on decay storage and final repository are discussed.
The socioeconomic investigations of possible impacts of the proposed repository for high-level nuclear waste at Yucca Mountain, Nevada, have been unprecedented in several respects. They bear on the public decision that sooner or later will be made as to where and how to dispose permanently of the waste presently at military weapons installations and that continues to accumulate at nuclear power stations. No final decision has yet been made. There is no clear precedent from other countries. The organization of state and federal studies is unique. The state studies involve more disciplines than any previous efforts. They have been carried out in parallel to federal studies and have pioneered in defining some problems and appropriate research methods. A recent annotated bibliography provides interested scientists with a compact guide to the 178 published reports, as well as to relevant journal articles and related documents.

The siting of nuclear waste facilities has been very difficult in all countries. Recent experience in Sweden indicates, however, that it may be possible, under certain circumstances, to gain local support for the siting of a high‐level nuclear waste (HLNW) repository. The article reports on a study of attitudes and risk perceptions of people living in four municipalities in Sweden where HLNW siting was being intensely discussed at the political level, in media, and among the public. Data showed a relatively high level of consensus on acceptability of at least further investigation of the issue; in two cases local councils have since voted in favor of a go‐ahead, and in one case only a very small majority defeated the issue. Models of policy attitudes showed that these were related to attitude to nuclear power, attributes of the perceived HLNW risk, and trust. Factors responsible for acceptance are discussed at several levels. One is the attitude to nuclear power, which is becoming more positive, probably because no viable alternatives are in sight. Other factors have to do with the extensive information programs conducted in these municipalities, and with the logical nature of the conclusion that they would be good candidates for hosting the national HLNW repository.

"Offers an account of how Western Shoshone, Southern Paiute, and Skull Valley Goshute peoples and nations prevented the construction of two high-level nuclear waste sites on their lands and how two sets of rhetorical tactics-Indigenous Lands rhetorics and national interest rhetorics-played an important role in these efforts"--

The Nuclear Waste Policy Act of 1982 authorized the U.S. Department of Energy (DOE) to evaluate monitored retrievable storage (MRS) as an option to manage spent fuel and high‐level radioactive waste. In 1987, the DOE sought Congressional approval for construction of an MRS at a site identified in Tennessee, despite adamant opposition from the State. An amendment in late 1987 nullified DOE's proposal, and established the MRS Commission and the High‐Level Nuclear Waste Negotiator, institutions created as a result of the DOE/Tennessee dispute. This article analyzes DOE's siting attempt in Tennessee, the actions of the Commission and Negotiator, and examines the prospects for implementation of nuclear waste policy.
