I. Introduction

The Yucca Mountain Review Plan (YMRP) (July 2003, NUREG-1804, Revision 2) provides guidance for U.S. Nuclear Regulatory Commission (NRC) Division of High-Level Waste Repository Safety (HLWRS) staff to evaluate a U.S. Department of Energy (DOE) license application for a geologic repository. NRC has prepared Interim Staff Guidance (ISG) to provide clarifications or refinements to the guidance provided in the YMRP. NRC is soliciting public comments on Draft HLWRS-ISG-03, which will be considered in the final version, or subsequent revisions, to HLWRS-ISG-03.

II. Summary

The purpose of this notice is to provide the public with an opportunity to review and comment on draft HLWRS-ISG-03, which is to supplement the YMRP, for the NRC staff review of consequence estimates for the preclosure safety analysis, and the associated radiation protection program that will be implemented by DOE during geologic repository operations area operations.

This ISG revises Sections and of the YMRP. A sufficient description of the radiation protection program and adequate technical bases for consequence estimates are needed to demonstrate compliance with the performance objectives in Code of Federal Regulations (CFR), Title 10, Part 63 (10 CFR Part 63), and radiation protection requirements of 10 CFR Part 20.
