Andras goal of Sustainability
As nuclear power assumes an increasingly important role in meeting the nation's requirements for electrical energy, the quantity of radioactive wastes will also increase. The wastes of primary concern -<br/>designated "high-level" and "alpha" wastes - contain radioactive nuclides that decay so slowly as to require that they be isolated from the biosphere for thousands of years.
Geologic repositories for radioactive waste are evolving<br/>from conceptualization to the development of specific<br/>designs. Estimates of long-term hazards must be based<br/>upon quantitative predictions of environmental releases<br/>over time periods of hundreds of thousands of years and<br/>longer.
19th Annual Symposium-Geological Disposal of Nuclear Waste
The importance of social and institutional issues in the siting of nuclear waste facilities has been recognized in recent years. Limited evidence from a survey of rural Wisconsin residents in 1980 indicates that incentives may help achieve the twin goals of increasing local support and decreasing local opposition to hosting nuclear waste facilities.

Solving the United States' high level nuclear waste<br/>disposal dilemma is vital to our energy independence and<br/>economic growth. The issue has been stalled for decades and<br/>presently faces enormous political obstacles despite renewed<br/>government effort to achieve a solution.
News item from NEI summarizing siting process for nuclear waste repositories in Sweden, Finland and France.
What are the essential elements of technically credible, workable, and publicly acceptable regulations for disposal (in geologic repositories)?
The study of geosciences and their relation to nuclear waste disposal and<br/>management entails analyzing the hydrology, chemistry, and geometry of the<br/>nuclear waste migration process. Hydrologic effects are determined by<br/>analyzing the porosity and permeability (natural and induced) of rock as well,<br/>as pressures and gradients, dispersion, and aquifer length of the system.<br/>Chemistry parameters include radionuclide retardation factors and waste<br/>dissolution rate.

The U.S. Nuclear Regulatory Commission (NRC) is amending its regulations governing the disposal of high-level radioactive wastes in a proposed geologic repository at Yucca Mountain, Nevada. The final rule implements the U.S. Environmental Protection Agency’s (EPA’s) revised standards for doses that could occur after 10,000 years, but within the period of geologic stability.
Isolation in a geologic setting has been the generally favored solution to the high-level radioactive waste (HLW) problem since a scientific basis for nuclear waste management began to be formulated over half a century ago. Although general features of suitable settings have been enumerated, quantitative measures of the safety of geologic isolation of HLW are challenging to devise and to implement.
The research reported here was initiated in January 1980 and performed for the Office of Policy and Evaluation, U.S. Department of Energy. The study arises from recognition by the DOE that the resolution of institutional issues is vital to the establishment of facilities to dispose of high-level radioactive waste (HLW). The disposal of HLW is an intensely difficult public policy problem.
This research report is part of the research programme International Socio-Technical Challenges for Implementing Geological Disposal (InSOTEC; see www.insotec.eu). The research programme is funded by the Seventh Framework Programme Theme [Fission-2010-1.1.2] [Research activities in support of implementation of geological disposal] (Grant agreement no: 269906).
A program leading to the establishment in FY I983 of a pilot plant for storing radioactive wastes in bedded salt is described. The program consists of laboratory and field investigations of factors affecting the suitability of a specific site in southeastern New Mexico; of more generally applicable problems associated with geohydrology and rock mechanics; and of considerations bearing on the operational safety of a pilot plant repository. Tasks concerned with the engineering development and design of the facility are also included.
The disposal of radioactive waste in the proper geologic environment offers a high potential for isolating the waste from man's environment for the period of time required for the waste to decay to innocuous levels. As part of the National Waste Terminal Storage Program, the Savannah River Laboratory has responsibility for studies related to the storage of waste in the geologic environment in the Southeast.
This report describes the history, recent developments and the current situation of the management of highly radioactive waste and spent nuclear fuel in the Czech Republic, with a particular focus on the development of geological disposal for this kind of waste. Special attention is given to the interplay of social and technical aspects of the process. The first chapter gives an overview of the state of affairs and sketches out the trajectories leading to it.
Proposals to site, construct and operate a radioactive waste disposal facility in Sweden will be supported by performance assessments (PAs). Such PAs will require a range of expert judgements to be made. As part of SKI’s preparation for reviewing SKB’s Pas and for conducting independent PAs, SKI has identified a need for further research on the treatment of expert judgement in PA.
Posiva Oy is studying the Finnish bedrock for the geological disposal of spent nuclear fuel. The study is based on the site selection research programme started originally in 1983. The programme is in accordance with the decision in principle by the Council of State in 1983 and aims at the selection of one site in 2000. Four sites, Hastholmen in Loviisa, Kivetty in Aanekoski, Olkiluoto in Eurajoki and Romuvaara in Kuhmo, have been studied in detail. This report summarises the results of the site investigations carried out at Kivetty.

There are two waste management R&D programs of national significance that are being administered for ERDA by the Union Carbide Corporation — Nuclear Division (UCC/ND). The National Waste Terminal Storage (NWTS) program is concerned with the development of geologic repositories for commercial nuclear fuel cycle wastes, and is organized as the Office of Waste Isolation within UCC/ND.
