r plants by requiring conformance with appropriate editions of specified published industry codes and standards. To meet the requirements of General Design Criterion 1 and 10 CFR § 50.55a, Regulatory Guide 1.26," Quality Group Classification and Standards," is used. This regulatory guide describes an acceptable method for determining quality standards for Quality Group B, C, and D water- and steam-containing components important to safety of water-cooled nuclear power plants. III. REVIEW PROCEDURES The table provided by the applicant identifying pressure vessel components, piping, pumps and valves, and the corresponding component Code, Code Edition, applicable Addenda, and, when required, the component order date of each ASME 5.2.1.1-2 Rev 2 - July 1981 Section III, Class 1 and 2 component within the reactor coolant pressure boundary, is checked for compliance with Section 50.55a of 10 CFR Part 50. This review is applicable to CP and OL applications. For those components within the reactor coolant pressure boundary that are not in compliance with the rules of Section 50.55a, a review of the Code, Code Addenda, and SAR is performed to identify the specific sections of the Code with which the component does not comply. A decision to accept a component which js not fully in compliance with the rules is based on a judgment of the relative importance of the specific provisions in the Code or Code Addenda not complied with, and a determination that any noncompliance will not result in an unacceptable level of safety and quality. If the staff's concerns are not resolved in a satisfactory manner, a staff position is taken requiring conformance with the rules of Section 50.55a. IV. EVALUATION FINDINGS The reviewer should verify that sufficient information is contained in the SAR and amendments and that his evaluation supports conclusions of the following type, which are to be included in the staff's safety evaluation report: The staff concludes that system components are in
