Coordinated reviews that interface with the overall review of the CVCS by CMEB are performed by other branches as follows. The Reactor Systems Branch (RSB) reviews the CVCS flow capacity and injection pressure to verify that specified acceptable fuel design limits are not exceeded fol- lowing a postulated LOCA in evaluating the ECCS function as part of its primary review responsibility for SRP Sections 6.3, 15.6.1, and 15.6.5. RSB also reviews CVCS malfunctions that can result in a decrease in boron concentration in the reactor coolant to assure that fuel damage limits are not exceeded and that adequate time is available to terminate the dilution before the shutdown margin has been eliminated as part of its primary review responsibility for SRP Section 15.4.6. The Core Performance Branch (CPB) evaluates the injection of borated water into the RCS to meet combined reactivity control system redundancy and capability require- ments of GDC 26 and 27 as part of its primary review responsibility for SRP Section 4.3. The liquid, solid, and gaseous waste treatment and process and effluent radiological monitoring aspects of the CVCS are reviewed in SRP Sections 11.2, 11.3, 11.4, and 11.5, respectively, by the Effluent Treat- ment Systems Branch (ETSB) as part of its primary review responsibility for those sections. The Radiation Assessment Branch (RAB), as part of its primary review responsibility for SRP Sections 12.1 and 12.3, reviews the system with respect to maintaining occupational radiation exposure as low as reasonably achievable (ALARA) and to providing radiation protection design features, respectively. The Instrumentation and Control Systems Branch (ICSB) and the Power Systems Branch (PSB) evaluate the adequacy of the design, installation, inspection, and testing of all electrical systems (sensing, control, and power) required to provide the safety-related func- tions of the CVCS as part of their primary review responsibility for SRP Sections 7.1, 7.6, and
