REVIEW RESPONSIBILITIES The organization responsible for review of reactor thermal-hydraulic systems in pressurized- water reactors (PWRs) or the organization responsible for review of reactor thermal-hydraulic systems in boiling-water reactors (BWRs) has overall responsibility for the reviews performed under this standard review plan (SRP). Primary and Secondary organizations responsible for the review of various components and subsystems associated with the reactor coolant system (RCS) are shown under Areas of Review below. RCS design bases, descriptions, evaluations, and necessary tests and inspections for the components or subsystems (including radiological considerations from the viewpoint of how radiation affects operation, and the viewpoint of how radiation levels affect the operators and capabilities of operation and maintenance) are to be evaluated for each of the specific Areas of Review below. Additional required evaluations are also specified under Areas of Review. I. AREAS OF REVIEW This section pertains to various components and subsystems within, or associated with, the RCS out to, and including, isolation valves. This is normally called the reactor coolant pressure boundary, as defined in Title 10, Section 50.2(v), of the Code of Federal Regulations. These components and subsystems differ for various types and designs of reactors. Principal components or subsystems might include the following: • reactor coolant pumps (RCPs) / circulation pumps [BWR] • steam generators • RCS piping and valves • main steamline flow restriction 5.4-2 Revision 2 - March 2007 • pressurizer • reactor core isolation cooling (RCIC) system [BWR] / isolation condenser system (Economic Simplified BWR [ESBWR]) • residual heat removal (RHR) system / passive residual heat removal system (Advanced Light-water Reactor [ALWR]) / shutdown cooling mode of the reactor water cleanup system [ESBWR] • reactor water cleanup system (RWCS) [BWR] / reactor water
