NUREG-0800 U.S. NUCLEAR REGULATORY COMMISSION STANDARD REVIEW PLAN BRANCH TECHNICAL POSITION 3-2 CLASSIFICATION OF BWR/6 MAIN STEAM AND FEEDWATER COMPONENTS OTHER THAN THE REACTOR COOLANT PRESSURE BOUNDARY REVIEW RESPONSIBILITIES Primary - Organization responsible for mechanical engineering reviews Secondary - Organizations responsible for the review of component performance and testing A. BACKGROUND At various times, the NRC staff has discussed with the General Electric Company the subject of appropriate classification criteria in boiling water reactor (BWR) plants for main steam system components. These discussions have included consideration of components that are (a) not classified as safety related items but are located downstream of the isolation valves, (b) not specifically designed to seismic Category I standards, and (c) not housed in Seismic Category I structures. To date, BWR plant reviews have resulted in various approaches for different individual applications. While these different approaches have resulted in acceptable levels of safety in each case, they have necessitated time-consuming case-by-case reviews. The GESSAR (PDA) BWR/6 application, which was reviewed as part of the NRC's standardization program, includes this portion of the BWR plant. BTP 3-2-2 Revision 2 - March 2007 In the course of the GESSAR PDA review, the NRC staff has identified a systematic basis for classification of such components that will result in an acceptable and uniform design basis for the main steam
