actor coolant system water chemistry necessary to meet PWR reactor coolant system water chemistry technical specifications. E. General Design Criterion 29, as it relates to the reliability of the CVCS to provide negative reactivity to the reactor by supplying borated water to the reactor coolant system in the event of anticipated operational occurrences. F. General Design Criteria 33 and 35 as they relate to the CVCS capability to supply reactor coolant makeup in the event of small breaks or leaks in the reactor coolant pressure boundary, to function as part of ECCS assuming a single active failure coincident with the loss of offsite power, and to meet ECCS technical specifications. G. General Design Criteria 60 and 61 as they relate to CVCS components having provisions for venting and draining through closed systems. H. TMI Action Plan item III.D.1.1 of NUREG-0737, equivalent to 10 CFR 50.34(f)(2)(xxvi) for applicants subject to 10 CFR 50.34(f), with respect to the provisions for a leakage detection and control program to minimize the leakage from those portions of the CVCS system outside of the containment that contain or may contain radioactive material following an accident.44 I. 10 CFR 50.63, "Loss of All Alternating Current Power," paragraph (a)(2), in regard to the ability of the CVCS systems to provide sufficient capacity and capability to ensure that the core is cooled in the event of a station blackout. If the CVCS system is 45 necessary to support a plant SBO withstand or coping capability as required by 10 CFR 50.63, the positions in Regulatory Guide 1.155 regarding CVCS system design provide an acceptable method for showing compliance.46 Other specific criteria used to review the CVCS and BRS design follows. 1. The CVCS should include provisions for monitoring: a. temperature upstream of the demineralizer to assure that resin temperature limits are not exceeded, and b. filter demineralizer differential pressure to assure that pressure differential
