ntrols for the reactor water 69 cleanup system to assure ensure that monitors are provided for: a. Conductivity of demineralizer effluent. b. Temperature and conductivity of demineralizer influent. c. Differential pressure across the demineralizer and across the resin strainers. CMEBEMCB ensures that system controls are responsive to the monitor indications to 70 maintain the required temperature and flow and that conductivity meters cover the entire range up to mandatory shutdown as delineated in the plant technical specifications in the final safety analysis report (FSAR). 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.71 IV. EVALUATION FINDINGS CMEBEMCB verifies that sufficient information has been provided and that the review is 72 adequate to support conclusions of the following type, to be included in the staff's safety evaluation report: The reactor water cleanup system (RWCS) will be used to aid in maintaining the reactor water purity and to reduce the reactor water inventory as required by plant operations. Our review has included piping and instrumentation diagrams and process diagrams along with descriptive information concerning the system design and operation. 5.4.8-11 DRAFT Rev. 3 - April 1996 The staff concludes that the proposed design of reactor water cleanup system (RWCS) is acceptable and meets the relevant requirements of General Design Criteria 1, 2, 14, 60, and 61. This conclusion is
