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.

Thorough long-term studies have shown that the Finnish bedrock is suitable for the permanent isolation of spent nuclear fuel from organic nature. Legislation requires that besides safety, an assessment be made of any other environmental impacts of the final disposal facility. Environmental impact assessment (EIA) in respect of the final disposal facility for spent nuclear fuel got under way in 1997 when Posiva Oy, which is responsible for the project, began work on an EIA programme.
The U.S. Nuclear Regulatory<br/>Commission (NRC) is proposing<br/>licensing criteria for disposal of spent<br/>nuclear fuel and high-level radioactive<br/>wastes in the proposed geologic<br/>repository at Yucca Mountain, Nevada.<br/>These criteria will address the<br/>performance of the repository system at<br/>Yucca Mountain, a system that must<br/>comprise both natural and engineered<br/>barriers.
In mid-1997, a Wyoming-led group of companies announced plans to develop a private interim spent fuel storage project in Wyoming to be known as the Owl Creek Energy Project. The idea for the Wyoming project had been developed under the earlier 1990s Nuclear Waste Negotiator Program. During that earlier activity, the project would have been a U.S. Department of Energy (DOE) project.
The concept of Geosphere Perfonnance Indices (GPis) is proposed. The "performance"<br/>refers to the geosphere's capacity to retain/contain radionuclides in the event of their accidental<br/>release at some point in time. The GPis are based on the Lagrangian stochastic-analytical<br/>framework for transport in the subsurface and are believed to render useful tools in performance<br/>assessment studies in general and in the site selection process in particular.
