Abstract

Volume 2, "Repository Safety Before Permanent Closure," of this Safety Evaluation Report (SER) documents the U.S. Nuclear Regulatory Commission (NRC) staff's review and evaluation of the U.S. Department of Energy's (DOE) Safety Analysis Report (SAR), entitled, "Repository Safety Before Permanent Closure," provided by DOE on June 3, 2008, as updated by DOE on February 19, 2009. In its application, DOE seeks authorization from the Commission to construct a repository for high-level radioactive waste at Yucca Mountain, Nevada. The NRC staff also reviewed information DOE provided in response to the NRC staff's requests for additional information and other information that DOE provided related to the SAR. In particular, SER Volume 2 documents the results of the NRC staff's evaluation to determine whether the proposed repository design complies with the performance objectives and requirements that apply before the repository is permanently closed. Based on its review, and subject to the proposed conditions of Construction Authorization documented in Volume 2 of this SER, the NRC staff finds, with reasonable assurance, that DOE has demonstrated compliance with the NRC regulatory requirements for preclosure safety. This includes "Performance objectives for the geologic repository operations area through permanent closure" in 10 CFR 63.111, "Requirements for preclosure safety analysis of the geologic repository operations area" in 10 CFR 63.112, and "Preclosure Public Health and Environmental Standards" in 10 CFR Part 63, Subpart K.
