REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of mechanical engineering issues Secondary - None I. AREAS OF REVIEW This section is used to verify whether the acceptable component codes (i.e., applicable ASME Code Class), code editions, and addenda required by 10 CFR 50.55a are identified for component construction. The review under this section is coordinated closely with the review described in SRP Section 3.2.2. More detailed review of compliance with ASME Code requirements for the component code class (e.g., component welds verified to meet requirements applicable for the Code Class) is under many other SRP sections. The applicant's framework for compliance with 10 CFR 50.55a requirements for application of codes during the inservice phase of the component life is also reviewed in many other SRP sections (e.g., 3.9.6, 5.2.4, 6.6, etc.). The specific areas of review are as follows: 1. To establish that pressure-retaining components of the reactor coolant pressure boundary (RCPB) and other safety-related fluid systems of water-cooled nuclear power plants comply with the Codes and Standards Rule, 10 CFR 50.55a, applicants are required to provide a table in the safety analysis report (SAR) identifying pressure vessels, piping, pumps and valves, and the component code, code edition, and applicable addenda, (where applicable) for each component. 10 CFR 50.55a 1 Editions of the Code prior to 1971 use the term Class A in lieu of Class 1. 2 “Constructed,” as used herein, is an all-inclusive term comprising material certification, design, fabrication, examination, testing, inspection, and certification required in the manufacture and installation of components. 3 Editions of the Code prior to 1971 use the term Class C in lieu of Class 2. 5.2.1.1-2 Revision 3 - March 2007 requires that RCPB pressure-retaining components meet requirements for Class 11 components and be constructed2 in accordance with the rules of the American Society of
