eet the requirements of General Design Criterion 1. This conclusion is based on the following: The applicant has met the requirements of 10 CFR § 50.55a and General Design Criterion 1 with respect to the construction of structures, systems, and components important to safety to quality standards. The requirements have been met by assuringensuring that the components of the reactor coolant pressure boundary, as 46 defined by the rules of 10 CFR § 50.55a, have been properly classified in Table x.x-x of the SAR as ASME Section III, Class 1 (Quality Group A) components, except for those reactor coolant pressure boundary components which meet the exclusion requirements of footnote 2 of the rule10 CFR 50.55a(c). These reactor coolant pressure boundary 47 components are classified Quality Group B in accordance with the guidance provided in Regulatory Position C.1 of Regulatory Guide 1.26 and are constructed as ASME Section III, Class 2 components. Table x.x-x identifies the component Code, Code Edition, and Code Addendaapplicable Addenda, and, when required, the order date for each Quality 48 Group A component such as: reactor vessel, steam generators (primary side), pressurizer, reactor coolant pumps, pressurizer relief valves, control valves, block valves, other reactor coolant pressure boundary valves, and interconnecting piping of the reactor coolant pressure boundary and each Quality Group B component such as: steam generators (secondary side) and interconnecting piping and valves of the reactor coolant pressure boundary which meet the exclusion requirements of footnote 2 of the rule10 CFR 50.55a(c).49 The requirements of 10 CFR 50.55a have been met by ensuring that components defined therein that are not part of the reactor coolant pressure boundary have been properly classified in Table x.x-x of the SAR as ASME Section III, Class 2 (Quality Group B) or Class 3 (Quality Group C). These components are acceptably classified as Quality Group B or C based upon the
