rmining quality standards for Quality Group B, C, and D water- and steam-containing components important to safety of water-cooled nuclear power plants. Technical Rationale The technical rationale for application of the acceptance criteria for compliance with General Design Criterion 1 and 10 CFR 50.55a is discussed in the following paragraphs:31 A. Compliance with General Design Criterion 1 requires that components be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety function to be performed. SRP Section 5.2.1.1 cites Regulatory Guide 1.26 to provide quality group classifications for water, steam, and radioactive waste containing components (pressure vessels, piping, pumps, valves, and storage tanks) that are commensurate with the importance of the safety function to be performed. Conformance with these quality group classifications requires that components of the RCPB and other specified components intended to contain radioactive materials meet the requirements of Section III of the ASME Code. The Code imposes specific requirements to ensure that these components will perform 32 DRAFT Rev. 3 - April 1996 5.2.1.1-4 acceptably, commensurate with their intended safety function, when designed in accordance with ASME Code provisions. The staff considers these requirements adequate to provide assurance that these components will perform acceptably, commensurate with the importance of their safety function, and will contain radioactive materials.33 B. Section 50.55a of 10 CFR requires that components be designed, fabricated, erected, constructed, tested, and inspected to quality standards commensurate with the importance of the safety function to be performed. 10 CFR 50.55a specifies that components of the RCPB and Quality Group B and C 34 components (as defined in Regulatory Guide 1.26) must meet the requirements of Section III of the ASME Code. The Code imposes specific requirements to ensure that 35 these
