nment spray water to return from the upper compartment to the sumps in the lower compartment). The bypass area capability of the plant should be based on analyses of the spectrum of postulated reactor coolant system pipe breaks, and should be about 3.3 square meters (35 square feet) or greater. 30 4d. In meeting the requirements of General Design Criteria 39 and 40 regarding the inspection and testing of containment heat removal systems, the design of the ice condenser system and return fan system should incorporate provisions for periodic inservice inspection and testing of essential system components; e.g., the ice baskets and doors, the ice condenser temperature monitoring system, the available mass of ice, and return air fan performance and controls. 5e. In meeting the requirements of General Design Criterion 16 regarding the containment design conditions important to safety, inadvertent operation of engineered safety features (e.g., the return air fan system or the containment spray system) should not cause the external design pressure of the primary containment to be exceeded. This may be accomplished through conservative containment design, use of vacuum relief devices, or electrical interlocks that preclude inadvertent operation of the spray and fan systems. DRAFT Rev. 3 - April 1996 6.2.1.1.B-6 6f. In meeting the requirements of General Design Criteria 13 and 64, and 10 CFR 50.34(f)(2)(xvii) (for those applicants subject to 10 CFR 50.34(f)), instrumentation 31 capable of operating in the post-accident environment should be provided to monitor the containment atmosphere pressure and temperature and the sump water level and temperature following an accident. The instrumentation should have adequate range, accuracy, and response to assure that the above parameters can be tracked and recorded throughout the course of an accident.
