Content:
4 - March 2007 5. GDC 45 requires CWS design for appropriate periodic inspection of important components (e.g., heat exchangers and piping) to ensure system integrity and capability. GDC 45 applies to this SRP section because the reviewer evaluates the reactor auxiliary CWS for whether appropriate periodic inspection of important components (e.g., heat exchangers and piping) ensures the integrity and capability of the system to perform its safety-related functions during normal operations, anticipated operational occurrences, and accident conditions. In addition, the CWS must be able to prevent or mitigate the consequences of an accident. GDC 45 requirements provide assurance that important CWS components can be inspected, thereby ensuring system integrity and capability to perform design safety functions. 6. GDC 46 requires CWS design for appropriate periodic pressure and function testing to ensure the leak-tight integrity and operability of components, as well as the operability of the system as a whole, at conditions as close to the design basis as practical. GDC 46 applies to this SRP section because the reviewer evaluates the CWS for whether periodic system pressure and function testing will ensure the leak-tight integrity and operability of its components, as well as the operability of the system as a whole, at conditions as close to the design basis as practical. GDC 46 requirements provide assurance that components of the reactor auxiliary CWS can be tested, ensuring that it will be capable of performing intended safety functions. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements
