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. 1. System Boundary Subject to Inspection. The applicant’s or licensee’s definition of the RCPB is acceptable if it is in agreement with the following criteria: for pressurized water reactor (PWR) and boiling water reactor (BWR) nuclear power systems, the inspection requirements of 10 CFR 50.55a, as detailed in Section XI of the ASME Code, must be met for all Class 1 pressure-containing components (and their supports). The system boundary, as defined in 10 CFR 50.2, includes all pressure vessels, piping, pumps, and valves which are part of the reactor coolant system, or connected to the reactor coolant system, up to and including: A. The outermost containment isolation valve in system piping that penetrates the primary reactor containment. B. The second of two valves normally closed during normal reactor operation in system piping that does not penetrate primary reactor containment. 5.2.4-5 Revision 2 - March 2007 C. The reactor coolant system safety and relief valves. 2. Accessibility. The design and arrangement of system components are acceptable if adequate clearance is provided in accordance with Subarticle IWA-1500, “Accessibility,” of the ASME Code, Section XI. 3. Examination Categories and Methods. The examination categories and methods specified in the SAR are acceptable if they are in agreement with the criteria in Article IWB-2000, “Examination and Inspection,” of Section XI of the ASME Code. Every area subject to examination should fall within one or more of the examination categories in Article IWB-2000 and should be examined at least to the extent specified. The methods of examination for the
