wn, accident prevention or accident mitigation. Based on the review of the applicant's proposed design criteria and bases for the circulat- ing water system, the staff concludes that the design of the circula- ting water system is acceptable and meets the requirements of General Design Criterion 4. This conclusion is based on the following: The applicant has met the requirements of General Design Criterion 4 with respect to the effects of discharging water that may result from a failure of a component or piping in the CWS. Acceptance is based on provisions of the design that prevent flooding of safety-related areas so that the intended safety function of a system or compo- nent will not be precluded due to leakage from the CWS; or provisions of the design that 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; or provisions of the design such that malfunction of a component or piping of the CWS including an expansion joint will not have unacceptable 10.4.5-3 Rev. 2 - July 1981 adverse effects on the functional performance capabilities of safety-related systems or components. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations.
