isolate CWS flow out of the failed expansion joint unless the valve(s) have been designed to safety-grade requirements. The ASBSPLB reviews the descriptions and drawings in the SAR and determines that 26 provisions are incorporated in the design to prevent unacceptable flooding of areas containing safety-related equipment or to mitigate the consequences of flooding. 2. The ASBSPLB reviews the CWS to verify that the capability to detect leaks and to 27 secure the system quickly and effectively exists.28 3. Based on the information contained in the SAR, the reviewer verifies that the applicant's proposed methods for control of water chemistry and of long-term corrosion and organic fouling, and the chemical agents used for these purposes, are compatible with the system materials. For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.29 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his that the review 30 supports conclusions of the following type, to be included in the staff's safety evaluation report: The circulating water system includes all components and equipment necessary to provide the main condenser with a continuous supply of cooling water. The system is designed to nonnuclear safety, Quality Group D, requirements since it is not necessary for safe shutdown, accident prevention, or accident mitigation. Based on the review of the applicant's proposed design
