Content:
water system, as described in the applicant's safety analysis report (SAR), is based on meeting the requirements of General Design Criteria 4 as it relates to design provisions provided to accommodate the effects of discharging water that may result from a failure of a component or piping in the CWS. Compliance with GDC 4 is based on meeting the following: 1. Means should be provided to prevent or detect and control flooding of safety-related areas so that the intended safety function of a system or component will not be precluded due to leakage from the CWS. 2. Malfunction or a failure of a component or piping of the CWS including an expansion joint should not have unacceptable adverse effects on the func- tional performance capabilities of safety-related systems or components. III. REVIEW PROCEDURES The procedures below are used during the construction permit (CP) review to determine that the design criteria and bases and the preliminary design as set forth in the preliminary safety analysis report meet the acceptance criteria given in subsection II. For the review of operating license (OL) applications, the procedures are used to verify that the initial design criteria and bases have been appropriately implemented in the final design as set forth in the final safety analysis report. Upon request from the primary reviewer, the coordinating review branches will provide input for the areas of review stated in subsection I. The primary reviewer obtains and uses such input as required to assure that this review procedure is complete. The reviewer will select and emphasize material from this SRP section as may be appropriate for a particular case. 10.4.5-2 Rev. 2 - July 1981 1. Although the circulating water system is not safety related, a failure of this system, or any of its components, may affect a safety-related compo- nent or system. Since large quantities of water flow through the CWS, a leak or break in a component or pipe or expansion joint failure could cause
