ndards Institute/American Nuclear Society (ANSI/ANS) 57.1-1992. 4. Acceptance for meeting the relevant aspects of GDC 62 is based in part on ANSI/ANS 57.1-1992. The SRP is not a substitute for the NRC regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and to evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. GDC 2 requires that SSCs important to safety be designed to resist the effects of natural phenomena like earthquakes. 9.1.4-5 Revision 4 - July 2014 GDC 2 applies to SRP Section 9.1.4 because it specifies the natural phenomenon (i.e., earthquake) that must be considered in the LLHS and refueling cavity design. If not considered, an earthquake could overload LLHS and refueling cavity SSCs and cause unsafe conditions (e.g., a fuel assembly drop with the potential for a release of radioactive materials from damaged irradiated fuel or criticality accidents) or unacceptable personnel radiation exposures. SRP Section 9.1.4 cites RG 1.29, Position C.1 for safety-related portions and Position C.2 for nonsafety-related design portions. These positions provide guidance for meeting these requirements. Compliance with GDC 2 assures that LLHS and refueling cavity SSCs will perform their intended function of safely carrying loads that, if dropped, could cause unsafe conditions, and keeping personnel exposure to radiation within acceptable limits. 2. GDC 5 requires that SSCs important to safety not be shared among nuclear power units unless such sharing can be shown not to significantly impair their ability to perform
