cific SRP acceptance criteria acceptable to meet the relevant requirements of the NRC’s regulations identified above are set forth below. The SRP is not a substitute for the NRC’s regulations, and compliance with it is not required. Identifying the differences between this SRP section and the design features, analytical techniques, and procedural measures proposed for the facility, and discussing how the proposed alternative provides an acceptable method of complying with the regulations that underlie the SRP acceptance criteria, is sufficient to meet the requirements in 10 CFR 52.47(a)(9), “Contents of applications; technical information.” The same approach may be used to meet the requirements of 10 CFR 52.79(a)(41) for COL applications. If the NRC staff has endorsed a referenced standard in a regulatory guide, that standard constitutes an acceptable method for use in meeting the related regulatory requirement as described in the regulatory guide. If a referenced standard has not been endorsed in a regulatory guide, licensees and applicants may consider and use the information in the referenced standard, if appropriately justified, consistent with current regulatory practice. 1. NUREG-0588, “Interim Staff Position on Environmental Qualification of Safety Related Electrical Equipment,” Revision 1, July 1981 provides staff positions applicable to existing plants for assessing the compliance of an environmental qualification program with 10 CFR 50.49. For future plants, RG 1.89, “Environmental Qualification of Certain Electric Equipment Important to Safety in Nuclear Power Plants,” provides the principal guidance for implementing the requirements and criteria of 10 CFR 50.49 for environmental qualification of electrical equipment that is important to safety and located in a harsh environment. However, certain NUREG-0588 Category I guidance may be used if relevant guidance is not provided in RG 1.89. NUREG-0588 includes two sets of qualification
