Content:
formance 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 VWS 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. 9.2.7-15 Draft Revision 0 – July 2014 GDC 46 requirements provide assurance that components of the VWS 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 describe how facility design and procedures for operation will minimize, to the extent practicable, contamination of the facility and the environment, facilitate eventual decommissioning, and minimize, to the extent practicable, the generation of radioactive waste. 10 CFR 20.1406(a) applies to this SRP section because the VWS couples to the primary coolant system across heat exchangers, and the possibility of leakage of contaminated primary coolant via the heat exchangers into the VWS exists. RTNSS B and C and nonsafety-related nonrisk-significant: apply. 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 identified in Subsection II. One of the main objectives in VWS review is to determine its safety function. Some cooling systems are designed as entirely safety-related, other systems have only
