iance with the requirements of General Design Criteria (GDCs) 1, 2, 4, 5, 44, 45, and 46 for CWS SSCs. 3. The capability of the CWS to provide adequate cooling water to safety-related ECCS components, heating-ventilation-air conditioning (HVAC), and reactor auxiliary equipment for all planned operating conditions. 4. The functional performance requirements of the system, including the ability to withstand adverse operational (e.g., water hammer) and environmental occurrences, operability requirements for normal operation and requirements for operations during and following other postulated events. 5. Multiple performance functions (if required by system design to perform a safety function) assigned to the system and the necessity of each function for system support of emergency core cooling and safe shutdown. 6. The capability of the system surge tank to perform its intended function with considerations for system leakage. 7. The capability of the system to provide adequate cooling water during all operating conditions. 8. The sizing of the system for adequate design heat load transfer capability and appropriate design margin. 9. The effects of non-seismic Category I component failures on the seismic Category I portion of the system (e.g., containment penetrations). 9.2.7-4 Revision 0 – September 2015 10. The requirements for operational testing and in-service inspection of the system. 11. Instrumentation and control features necessary to accomplish design functions, including isolation of components for leakage or malfunctions and actuation requirements for redundant equipment. 12. Simplified reliability analyses using event-tree and fault-tree logic techniques. 13. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant’s proposed ITAAC associated with the SSCs related to this SRP section in accordance with SRP Section 14.3, “Inspections, Tests, Analyses,
