roposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 1. Acceptance for meeting the relevant aspects of GDC 2 is based on Regulatory Guide (RG) 1.29, Positions C.1 and C.2. 2. Acceptance for meeting the relevant aspects of GDC 5 is embodied within the other acceptance criteria. 3. Acceptance for meeting the relevant aspects of GDC 61 is based in part on the guidelines of American National Standards 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. Technical Rationale 9.1.4-5 Draft Revision 4 – June 2013 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. 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 design. If not considered, an earthquake could overload LLHS 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 non-safety-related design portions. These positions provide guidance for meeting these requirements. Compliance with GDC 2 assures that LLHS SSCs will perform their intended function of safely carrying loads that, if dropped, could cause unsafe conditions, keeping personnel exposures 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
