re considered: A. The process equipment, resin types, bed volumes, and RWCS capability are compared to those of similar reactors. B. The design flows and temperatures through the system to ensure that criteria for outlet temperature relative to resin temperature are met. C. The RWCS capability to process surplus refueling water prior to storage in the refueling water storage tanks or the condensate storage tanks. D. Redundant or parallel components which will permit cleanup, if required, during periods of equipment downtime or single active component failure. 3. The quality group and seismic design classification of the system are reviewed to compare the design to the guidelines of Regulatory Guides 1.26 and 1.29 to ensure conformance with Acceptance Criterion II.3, above. 4. The instrumentation and controls for the reactor water cleanup system are reviewed to 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. 5. The system controls are reviewed to ensure they 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). 6. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be
