time spans. For each case the design will be acceptable if minimum system requirements are met. 5. The spent fuel pool cleanup system and various auxiliary systems are designated as nonsafety-related systems and are designed accordingly (nonseismic Category I). These systems are evaluated to assureensure that their failure cannot affect the functional 107 performance of any safety-related system or component. The relationship and proximity between the nonsafety-related system and safety-related systems or components are determined by reviewing the integrated structure and component layout diagrams. Independent analyses, engineering judgment, and comparisons with previously approved systems are used to verify that where a nonsafety-related system interconnects or DRAFT Rev. 2 - April 1996 9.1.3-14 interfaces with the cooling system, its failure by any event or malfunction will not preclude adequate functional performance of the cooling system. 76. The cleanup system is also reviewed to assureensure that it has been designed with the 108 109 capability to maintain acceptable pool water conditions. The P&IDS and associated information provided in the SAR is reviewed to verify the following: a. A means has been provided for mixing to produce a uniform temperature throughout the pool. b. The cleanup system is reviewed by CMEBthe EMCB to verify they have the 110 capacity and capability to remove corrosion products, radioactive materials, and impurities so that water clarity and quality will enable safe operating conditions in the pool. This includes instrumentation and sampling to monitor the water purity and need for demineralizer resin replacement, including the chemical and radiochemical limits such as conductivity, gross gamma and iodine activity, demineralizer differential pressure, pH and crud level which are used to initiate corrective action. c. The capability for processing the refueling canal coolant during refueling operations has been provided. d. Provisions
