This work was performed to suggest possible strategies for geoscientific classifications in the siting process of a high-level repository. To develop a feasible method for geoscientific classifications, a number of factors of a philosophical character, related to the purpose of the classifications, need to be accounted for. Many different approaches can be visualized, and this report was not intended to present a complete classification methodology.

Comments contained in this document were received by the U.S. Department of Energy (DOE) on the Report of Early Site Suitability Evaluation (ESSE) of the Potential Repository Site at Yucca Mountain, Nevada, (Younker et al., 1992, SAIC 91/8000). Comments were received from the U.S. Department of Interior, the U.S. Nuclear Regulatory Commission, the State of Nevada, and several local affected governments in Nevada. No comments were received from members of the public.

In 1986, the U.S. Department of Energy (DOE) Waste Isolation Pilot Plant (WIPP) Project<br/>Office (WPO) (DOE-WPO) prepared a strategy _ for complying with the Environmental<br/>Protection Agency&#39;s (EPA&#39;s) Standards for the management of transuranic (TRU) waste. 2<br/>Section 3.2.2.2 of the DOE&#39;s report addressed compliance with the Assurance<br/>Requirements found in 40 CFR § 191.143 . One of the Assurance Requirements addresses<br/>the selection of repository sites that contain recoverable natural resources.

The potentially adverse condition identified at 10 CFR 60.122(c)(16), evidence of extreme<br/>erosion during the Quaternary Period, has been determined to not be present at Yucca<br/>Mountain. A literature search for typical hillslope erosion rates in the U.S. and the world was<br/>performed to establish a range of typical values for erosion rates. Low to moderate erosion<br/>rates in the U.S. were identified to range from 2 to 50 centimeters per thousand years (cm/ka)<br/>in semiarid environments.

This paper is about the U.S. Environmental Protection Agency (EPA) &quot;Environmental Standards for the Disposal of Spent Nuclear Fuel, High-Level and Transuranic Wastes, &quot; 40 CFR 191. These standards regulate the disposal of radioactive wastes in geologic repositories.

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. The Act on Nuclear Activities /1-1/ 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.

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 scientific investigations within SKB &#39;s research programme are a part of the work<br/>of designing a deep repository and identifying and investigating a suitable site.<br/>A balanced appraisal of the facts, requirements and assessments presented in connection<br/>with the preparation of R&D-Programme 86 11/led to the proposal to construct<br/>an underground research laboratory.

Consideration of the technical feasibility of Yucca Mountain in Nevada as the site for a high-level nuclear<br/>waste repository has led to an intense debate regarding the economic, social, and political impacts of the<br/>repository.
