cceptance criteria are based on meeting Commission policy and the relevant requirements of the following Commission regulations: 1. 10 CFR 50.36(c)(2)(ii)(D) – TS limiting condition for operation of a nuclear reactor must be established for a system, structure or component which operating experience or PRA has shown to be significant to public health and safety. SRP Acceptance Criteria Specific SRP acceptance criteria acceptable to satisfy the Commission’s policy on RTNSS and to meet the relevant requirements of the NRC regulations identified above are as follows for the review described in this SRP. The SRP is not a substitute for the NRC regulations, and compliance with it is not required. However, an applicant is required to identify and describe differences between the design features, analytical techniques, and procedural measures proposed 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 19.3-6 Revision 0 – June 2014 NRC regulations. The SRP acceptance criteria are derived from Commission direction and staff guidance published in multiple documents, including the following: 1. SECY-93-087, “Policy, Technical, and Licensing Issues Pertaining to Evolutionary and Advanced Light-Water Reactor ALWR Designs,” dated April 2, 1993 (ADAMS Accession No. ML003760768), and associated SRM, July 21, 1993 (ADAMS Accession No. ML003708056). 2. SECY-94-084, “Policy and Technical Issues Associated with the Regulatory Treatment of Nonsafety Systems in Passive Plant Designs,” dated March 28, 1994, and associated SRM, June 30, 1994 (ADAMS Accession No. ML003708068). 4. SECY-95-132, “Policy and Technical Issues Associated with the Regulatory Treatment of Nonsafety Systems (RTNSS) in Passive Plant Designs,” dated May 22, 1995, and associated SRM, June 28, 1995 (ADAMS Accession No. ML003708005). 5.
