AREAS OF REVIEW In order to establish that pressure-retaining components of the reactor coolant pressure boundary (RCPB) and other fluid systems important to safety of water-cooled nuclear power plants are in 4 compliance with the Codes and Standards Rule 10 CFR § 50.55a, an applicant is required to provide a table in histhe safety analysis report (SAR) identifying pressure vessels, piping, 5 pumps and valves, and the component Code, Code Edition, applicable Addenda, and component6 order date (where applicable) for each component. 10 CFR § 50.55a requires that pressure-retaining components of the reactor coolant pressure boundary be designated asRCPB 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, 3 fabrication, examination, testing, inspection, and certification required in the manufacture and installation of components. Editions of the Code prior to 1971 use the term Class B in lieu of Class MC. 4 d Editions of the Code prior to 1971 use the term Class C in lieu of Class 2. 4 DRAFT Rev. 3 - April 1996 5.2.1.1-2 meet requirements for Class 1 components and thereby be constructed in accordance with the 2 3 corresponding rules of the American Society of Mechanical Engineers (ASME) Boiler and 7 Pressure Vessel Code, Section III, Division 1 (Reference 4, hereafter the Code) , except for 8 components which meet the exclusion requirements of footnote 2 of the rule10 CFR 50.55a(c). 9 Components of the reactor coolant pressure boundary which meet the exclusion requirements of footnote 210 CFR 50.55a(c) may be classified as Quality Group B in accordance with 10 Regulatory Guide 1.26 and constructed as Class 2 components in accordance with the Code. The Codes and Standards Rule also requires that pressure-retaining components of other fluid
