R 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 compliance with 10 CFR §50.55a and meet 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 require- ments have been met by assuring that the components of the reactor coolant pressure boundary as 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 rule. These reactor coolant pres- sure boundary 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 Addenda for each Quality 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 rule. We reviewed the component Code, Code Edition, and Addenda, as applied to each of these reactor coolant pressure boundary components, and we find they are constructed in accordance with the requirements of the applicable Codes and
