CFR Part: 
CFR Title: 

Content:
the cooling water system shall be designed to permit appropriate periodic inspection of important components, such as heat exchangers and piping, to assure the integrity and capability of the system. GDC 45 applies to this SRP section because the reviewer evaluates the CWS for whether appropriate periodic inspection of important components (e.g., heat exchangers, chillers, and piping) ensures the integrity and capability of the system to perform its safety-related functions during normal operations, AOOs, and accident conditions. In addition, the CWS must be able to prevent or mitigate the consequences of a design basis accident. GDC 45 requirements provide assurance that important CWS components can be inspected, thereby ensuring system integrity and capability to perform design safety functions. 9.2.7-13 Revision 0 – September 2015 7. GDC 46 as to design provisions to permit appropriate periodic pressure and functional testing to assure; A. The structure and leaktight integrity of the components of the systems. B. The operability and the performance of active components of the system. C. The operability of the system as a whole and, under conditions as close to design as practical, the performance of the full operational sequence that brings the system into operation for reactor shutdown and for LOCAs, including operation of applicable portions of the protection system and the transfer between normal and emergency power sources. 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 CWS can be tested, ensuring that it will be capable of performing intended safety functions. 8. 10 CFR 20.1406(a), which requires that a DC or COL applicant to
