, to contain these alternative requirements. This guide conforms to a proposed amendment to 10 CFR 50.69 that was published in the Federal Register (68 FR 26511) on May 16, 2003. This draft regulatory guide is being developed to describe a method acceptable to the NRC staff for complying with the Commission’s regulations with respect to the categorization of SSCs that are considered in risk-informing special treatment requirements. Attached to this draft regulatory guide is the staff’s detailed comments on Draft Revision C of Nuclear Energy Institute's (NEI) 00-04, "10 CFR 50.69 SSC Categorization Guideline." (ADAMS Accession No. ML021910534). 2 Regulatory guides are issued to describe to the public methods acceptable to the NRC staff for implementing specific parts of the NRC’s regulations, to explain techniques used by the staff in evaluating specific problems or postulated accidents, and to provide guidance to applicants. Regulatory guides are not substitutes for regulations, and compliance with regulatory guides is not required. Regulatory guides are issued in draft form for public comment to involve the public in developing the regulatory positions. Draft regulatory guides have not received complete staff review; they therefore do not represent official NRC staff positions. The information collections contained in this draft regulatory guide are covered by the requirements of 10 CFR Part 50, which were approved by the Office of Management and Budget (OMB), approval number 3150-3011. The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid OMB control number. B. DISCUSSION This regulatory guide provides guidance for categorizing SSCs in accordance with their safety significance using the process described in Draft Revision C of Nuclear Energy Institute (NEI) 00-04, “10 CFR 50.69 SSC Categorization
