ns to construct and operate nuclear power ptlnts. These documents are made available to the public as part of the Commission's policy to Inform the nuclear Industry an the general public of regulatory procedures and policies. Standard review plans are not substitutes for regulatory guides or the Commison's regulations and compliance with them Is not required. The standard review plan sections era keyed to the Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants. Not all sections of the Standard Format have a corresponding review plan. Published standard review plans wllt be revised periodically, as appropriate.to accommodate comments and to reflect new Informa- tion end experience. Comments and suggestions for Improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission. Office of Nuclear Reactor Regulation, Washington. D.C. 205 c. The system is housed in structures designed to seismic Category I requirements. d. Failures of nonseismic Category I structures and components would not affect the safety-related functions of the EDECWS. 3. The PSB reviews the design of the EDECWS with respect to the following: a. Functional capability during periods of abnormally high water levels (the probable maximum flood). b. Capability to detect and control system leakage, including isolating portions of the system in the event of excessive leakage or component mal function. c. Measures to preclude long-term corrosion and organic fouling that would degrade system cooling performance, and the compatibility of any corrosion inhibitors or antifreeze compounds used with the materials of the system. d. The capacity of the EDECWS with regard to the manufacturer's recom- mended engine temperature differentials under adverse operating con- ditions. e. Provision of proper instruments and testing systems to permit opera- tional testing of the system. f. Provisions to assure that normal protective interlocks do not pre- clude engine
