SUBJECT:

PROPOSED RULEMAKING ON 10 CFR 50.69, DRAFT REGULATORY GUIDE DG-1121, AND NEI 00-04

During the 495th meeting of the Advisory Committee on Reactor Safeguards, September 12-14, 2002, the Committee reviewed (1) proposed rulemaking on 10 CFR 50.69, "Risk-Informed Categorization and Treatment of Structures, Systems, and Components for Nuclear Power Reactors;" (2) Draft Regulatory Guide DG-1121, "Guidelines for Categorizing Structures, Systems, and Components in Nuclear Power Plants According to Their Safety Significance;" and (3) the Nuclear Energy Institute document NEI 00-04 (Draft Revision C), "10 CFR 50.69 SSC [Structures, Systems, and Components] Categorization Guideline."

The ACRS agrees with the staff's proposal to issue the proposed 10 CFR 50.69 and DG-1121, which endorses NEI 00-04, for public comment. The Committee plans to continue to meet with the staff to discuss these documents as further progress is made.
