Content:
inspections, tests, and analyses are performed and the acceptance criteria met, the facility has been constructed and will operate in conformity with the combined license, the provisions of the Atomic Energy Act, and the NRC’s regulations. SRP Acceptance Criteria Specific SRP acceptance criteria acceptable to meet the relevant requirements of the NRC’s regulations identified above are as follows for the review described in this SRP section. The SRP is not a substitute for the NRC’s 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 evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 9.3.1-5 Revision 2 - March 2007 1. Acceptance for meeting the relevant aspect of GDC 1 is based on compliance with the criteria specified in American National Standards Institute/Instrument Society of America (ANSI/ISA) S7.3-R1981 related to minimum instrument air quality standards. 2. Acceptance for meeting the relevant requirements of GDC 2 as it relates to seismic classification is based on compliance to guidance provided in RG 1.29, Positions C.1 and C.2. 3. Acceptance for meeting the relevant requirements of GDC 5 as it relates to the sharing of safety-related SSCs is based on the criteria set forth here for CAS SSCs shared among multiple units. 4. Acceptance for meeting the relevant requirements of 10 CFR 50.63 as it relates to the CAS design and the ability of a plant to withstand for a specified duration and recover from a station blackout is based on RG 1.155. Technical Rationale CASs may be divided into subsystems that provide control air to safety-related components and systems and subsystems that provide compressed air to nonsafety-related components and systems. For the purposes of these
