nsidered acceptable if the periodic inspection of important CWS components ensures system integrity and capability to perform design safety functions. 7. Cooling Water System Testing. Information that addresses the requirements of GDC 46 regarding the testing of cooling water systems will be considered acceptable if periodic system pressure and function testing of the CWS 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. System operability should also be monitored through Technical Specifications in Chapter 16 of the safety analysis report (SAR). 8. Minimization of Contamination. Information that address the requirements of 10 CFR 20.1406 regarding minimization of contamination to the facility and the environment, and designs to facilitate eventual decommissioning, will be considered acceptable if the design identifies provisions to detect contamination that may enter as in-leakage from other systems, identifies potential collection points such as water treatment systems or system low points, and addresses the long-term control of radioactive material in the system. 9.2.7-10 Revision 0 – September 2015 Table II.1: SRP Acceptance Criteria Applicability for Nonsafety-Related SSCs of the Chilled Water System SRP Acceptance Criteria: RTNSS B RTNSS C All Other Nonsafety- Related 1. GDC 1 is applicable only for containment isolation functions. X X X 2. Compliance with GDC 2 is not required for RTNSS SSCs; however, RTNSS B SSCs should be designed to withstand the effects of natural phenomena without loss of function. RTNSS C SSCs are evaluated, utilizing the “graded approach philosophy,” against the effects of the most probable hazards (e.g., floods, winds, missiles, seismic events). As a result of this evaluation, RTNSS C SSCs maybe designed against the effects of natural phenomena. SRP Section 19.3 provides further guidance related to
