mineralizer and across the resin strainers. CMEB assures that system controls are responsive to the monitor indications to 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). IV. EVALUATION FINDINGS CMEB verifies that sufficient information has been provided and that the review is 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 main- taining 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. 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 based on the following: 1. The applicant has met the requirements of General Design Criterion 1 by designing, in accordance with the guidelines of Regulatory Guide 1.26, the portion of the RWCS extending from the reactor vessel and recirculation loops to the outermost primary containment isolation valves to Quality Group A and by 5.4.8-6 Rev. 2 - July 1981 designing, in accordance with position C.2.c of Regulatory Guide 1.26, the remainder of the RWCS outside the primary containment (excluding the precoating unit) to Quality Group C. 2. The applicant has met the requirements of General Design Criterion 2 by designing in accordance with positions C.1, C.2, C.3 and C.4 of Regulatory Guide 1.29, the portion of the RWCS extending from the reactor vessel and recirculation loops to the outermost primary containment isolation valves to seismic Category I. 3. The applicant has met the requirements
