This second version of the Olkiluoto Site Report, produced by the OMTF (Olkiluoto Modelling Task Force), updates the Olkiluoto Site Report 2004 (Posiva 2005) with the data and knowledge obtained up to December 2005.<br/>The main product of the modelling has been to develop a descriptive model of the site (the Site Descriptive Model), i.e. a model describing the geometry, properties of the bedrock and the water and the associated interacting processes and mechanisms.

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 Romuvaara.

Although some observers have concluded that the technology required to assure safe disposal of nuclear wastes is currently available, others have expressed concern about the stability of the institutions that might be required to maintain the isolation of nuclear wastes. Questions about institutional stability and other factors associated with nuclear power and nuclear waste have been the subject of some study in public opinion research.

This report is concerned with how America&#39;s public sector is handling the challenge of implementing a technical, environmental policy, that of managing the nation&#39;s high-level nuclear waste, as reflected in the attempt of the U.S. Department of Energy (DOE) to site a Monitored Retrievable Storage Facility (MRS) for high-level radioactive waste in Tennessee.

The U.S. Congress authorized the development of a monitored retrievable storage facility (MRS) as part of the high-level radioactive waste management system. The MRS will be used to receive, store, and stage shipments of intact spent fuel to the permanent repository. Early development of the MRS is crucial to honoring the long-standing Federal commitment to timely and adequate waste acceptance. The Department of Energy&#39;s (DO E) objective is initial waste acceptance at the MRS beginning in 1998.

The siting of the facilities for the disposal of spent nuclear fuel and other long-lived<br/>nuclear waste is one of the central remaining tasks within the Swedish waste programme.<br/>Work relating to the siting of the repository is being conducted in stages and will<br/>continue for most of the 1990:ies. This report describes the background to, the goals<br/>for and structure of SKB &#39;s activities relating to the siting of a deep geological<br/>repository.

The goal of radioactive waste management in Sweden is to dispose of all radioactive waste products generated at the Swedish nuclear power plants in a safe manner. Furthermore, all other radioactive waste that arises in Sweden shall be safely disposed of.<br/>The Act on Nuclear Activities requires that the owners of the Swedish nuclear power plants adopt the measures that are needed to achieve this goal. The owners of the Swedish nuclear power plants have commissioned the Swedish Nuclear Fuel and Waste Management Company (SKB) to implement the measures that are needed.<br/>

The U.S. Geological Survey&#39;s program for geologic and hydrologic evaluation of physiographic provinces to identify areas potentially suitable for locating repository sites for disposal of high-level nuclear wastes was announced to the Governors of the eight States in the Basin and Range Province on May 6, 1981. Representatives of Arizona, California, Idaho, New Mexico, Nevada, Oregon, Texas, and Utah, were invited to cooperate with the Federal Government in the evaluation process.

This paper is a first consideration of the MRWS White Paper on the framework for geological disposal. It is based primarily on discussions in Working Group D on July 21 2008 but also draws on CoRWM’s informal comments on the draft White Paper, on CoRWM’s recommendations as reported in 2006 and on an overview of the responses to the consultation that preceded the White Paper. There have been few opportunities, as yet, to discuss the White Paper through the CoRWM PSE process.

Final 40 CFR 40 Ruling on Environmental Radiation Protection Standards for Management and Disposal of Spent Nuclear Fuel , High-Level and Transuranic Radioactive Wastes

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 Hastholment.

In the Savannah River Site’s (SRS’) Solid Waste Management Program, a key to success is the Public Involvement Program. The Solid Waste Division at SRS manages the site’s transuranic, low-level, mixed, and hazardous wastes.

Repository performance assessment is analysis that identifies events and processes that might affect a repository system for isolation of radioactive waste, examines their effects on barriers to waste migration, and estimates the probabilities of their occurrence and their consequences. In 1983 Battelle Memorial Institute&#39;s Office of Nuclear Waste Isolation (ONWI) prepared two plans — one for performance assessment for a waste repository in salt and one for verification and validation of performance assessment technology. At the request of the U.S.

This white paper offers some suggestions about how to improve the process in the United States for developing facilities for geologic disposal of used nuclear reactor fuel and high-level radioactive waste. These suggestions look toward the future, and build on what I believe are the lessons that should be learned from the troubled Yucca Mountain repository project.

The principal factors that affected the scope of scientific investigations at Yucca Mountain over the last 20 years included both regulatory and technical aspects. Examples of regulatory factors include the regulations themselves as well as the associated quality assurance requirements. Examples of technical factors include the repository and waste package designs, new information that affected the post-closure safety basis, and technical reviews from peers, stakeholders and the regulators.

For those parts of the waste system that have already been taken into operation - transportation and handling systems, central interim storage facility for spent nuclear fuel (CLAB) and final repository for reactor waste (SFR)- the research and development stage has already largely been passed. The programme presented here therefore pertains primarily to the treatment and final disposal of spent fuel and the decommissioning of nuclear power plants.

Many nations and international agencies are working to develop improved technology and industrial capability for nuclear fuel cycle and waste management operations. The effort in some countries is limited to research in university laboratories on treating low-level waste from reactor plant operations.
