ntinue to be used (provided that they remain applicable) and the staff may consider new methodologies. The source term methodologies used should be applicable to the specific applicant or licensee and adequate to address EQ requirements. • RG 1.189, “Fire Protection for Nuclear Power Plants,” (Ref. 22) describes methods acceptable to the NRC staff to meet the regulatory requirements related to a fire protection program. RG 1.257, Rev. 0, Page 6 • RG 1.215, “Guidance for ITAAC Closure Under 10 CFR Part 52” (Ref. 23), describes a method for documenting the completion of ITAAC. • RG 1.248, “Guide for Assessing, Monitoring, and Mitigating Aging Effects on Electrical Equipment Used in Production and Utilization Facilities” (Ref. 24), describes an approach that is acceptable to the NRC staff to meet regulatory requirements for managing, monitoring, and mitigating the aging effects on electrical equipment. Purpose of Regulatory Guides The NRC issues RGs to describe methods that are acceptable to the staff for implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific issues or postulated events, and to describe information that the staff needs in its review of applications for permits and licenses. RGs are not NRC regulations and compliance with them is not required. Methods and solutions that differ from those set forth in RGs are acceptable if the licensee or applicant provides sufficient basis and information for the NRC staff to verify that the alternative methods comply with the applicable NRC regulations. Paperwork Reduction Act This RG provides voluntary guidance for implementing the mandatory information collections in 10 CFR Parts 50 and 52 that are subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et. seq.). These information collections were approved by the Office of Management and Budget (OMB), under control numbers 3150-0011 and 3150-0151, respectively. Send
