SUPPLEMENTARY INFORMATION: I. Introduction The Yucca Mountain Review Plan (YMRP) (July 2003, NUREG-1804, Revision 2) provides guidance for U.S. Nuclear Regulatory Commission (NRC) staff to evaluate a U.S. Department of Energy (DOE) license application for a geologic repository. NRC has prepared Interim Staff Guidance (ISG) to update and supplement the guidance provided in the YMRP. NRC is soliciting public comments on Draft HLWRS-ISG-04 “Preclosure Safety Analysis—Human Reliability Analysis”, which will be considered in the final version, or subsequent revisions, to HLWRS-ISG-04. II. Summary The purpose of this notice is to provide the public with an opportunity to review and comment on draft HLWRS-ISG-4, which is to supplement the YMRP, for the NRC staff review of human reliability analysis (HRA) contained in the DOE preclosure safety analysis. Specifically, this ISG identifies additional NRC guidance available to aid the HRA review and provides additional considerations in areas of the license application review that are potentially affected by HRA. This ISG revises Sections 2.1.1.2, 2.1.1.3, 2.1.1.4, 2.1.1.6, 2.1.1.7, 2.5.5, and 2.5.6 of the YMRP. III.
