This record of siting a geologic repository for high-level radioactive wastes (HL W) and spent fuel describes the many investigations that culminated on Demnber 22, 1987 in the designation of Yucca Mountain (YM), as the site to tmdergo detailed geologic characterization. It recounts the important issues and events that have been instrmnenta1 in shaping the course of siting over the last three and one half decades. In this long task, which was initiated in 1954, more than 60 regions, areas, or sites involving nine different rock types have been investigated.

The Nuclear Waste Policy Act of 1982, as amended, established a statutory basis<br/>for managing the nation’s civilian (or commercially produced) spent nuclear<br/>fuel. The law established a process for siting, developing, licensing, and constructing<br/>an underground repository for the permanent disposal of that waste.<br/>Utilities were given the primary responsibility for storing spent fuel until it is<br/>accepted by the federal government for disposal at a repository, which originally<br/>was expected to begin operating in 1998.

In an attempt to facilitate the resolution of contentious environmental problems, public agencies are increasingly using collaborative approaches wherein stakeholders participate in the decision-making process. A dilemma for the design of collaborative approaches is the technical complexity of many environmental problems. How can members of the public play a meaningful role in decisions that involve complicated scientific arguments?

In RD&D-Programme 92, SKB presented a partially new strategy for its activities. The new strategy entailed a focusing and concentration on the implementation of deep disposal of a limited quantity (about 800 tonnes) of encapsulated spent nuclear fuel during the coming 20-year period. Following this initial deposition, the results of the work will be evaluated, and only then will a decision be taken as to how and when regular deposition of the main body of the fuel and other long-lived nuclear waste will take place.

First Meeting of National Research Council Committee for Yucca Mountain Peer Review: Surface Characteristics, Preclosure Hydrology, and Erosion

This study presents a synthesis of information and interpretations relevant to surficial processes at the Yucca Mountain Site. The report is part of the technical basis which will be used to evaluate the suitability of Yucca Mountain, Nevada, as a site for a mined geologic repository for the permanent disposal of high-level radioactive waste and spent nuclear fuel. It provides a description of the surface characteristics, preclosure hydrology, and erosion at the Yucca Mountain Site. This report will provide the technical basis to evaluate three technical guidelines from the U.S.
