REVIEW RESPONSIBILITIES Primary - Chemical Engineering Branch (CMEB)Materials and Chemical Engineering Branch (EMCB)1 Secondary - None I. AREAS OF REVIEW At the construction permit (CP), standard design certification, or combined license (COL) stage 2 of review, the CMEBEMCB reviews the information in the applicant's safety analysis report 3 (SAR) in the specific areas that follow. At the operating license (OL) or COL stage of review, 4 the CMEBEMCB review consists of confirming the design accepted at the CP or standard 5 design certification stage and evaluating the adequacy of the applicant's technical specifications 6 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 provisions 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 assureensure the system capacity will 7 meet the reactor coolant specifications are reviewed. DRAFT Rev. 3 - April 1996 5.4.8-2 3. The quality group and seismic design criteriaclassification are reviewed. 8 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/demineralizer resins, and (b) monitoring impurity removal (conductivity measurements), differential pressure across
