REVIEW RESPONSIBILITIES Primary - Chemical Engineering Branch (CMEB) Secondary - None I. AREAS OF REVIEW At the construction permit (CP) stage of review, the CMEB reviews the information in the applicant's safety analysis report (SAR) in the specific areas that follow. At the operating license (OL) stage of review, the CMEB review consists of con- firming the design accepted at the CP stage and evaluating the adequacy of the applicant's technical specifications in these areas. 1. The design of components, design features which influence system availability and reliability, and interconnections with the reactor primary coolant and radwaste systems are reviewed. Removal of chemical impurities and fission products by the reactor water cleanup system (RWCS) is considered. The provi- sions for isolating the RWCS from the reactor system following liquid poison injection, holding filter and demineralizer beds in place if system flow is decreased, straining resins from return flows to the primary system, component venting, and resin transfer are reviewed. 2. The component design parameters for flow, temperature, pressure, heat removal capability, and impurity removal capability to assure the system capacity will meet the reactor coolant specifications are reviewed. 3. The quality group and seismic design criteria are reviewed. 4. The instrumentation and process controls provided to ensure proper system operation and system isolation when necessary, including instrumentation for (a) automatic system isolation to prevent removal of liquid poison in the event of standby liquid control system actuation and to prevent damage to the filter/ Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation stff responsible for the review of applications to construct and operate nuclear power plants.
