S are designed, to the extent practical, to withstand full RCS pressure. If designing the CVCS with an ultimate rupture strength capable of withstanding full RCS pressure is not possible, the reviewer verifies that appropriate compensating measures have been taken in accordance with the review provided in SRP Section 3.12 (proposed).17 b. The Core Performance Branch (CPB) SRXB evaluates the injection of borated 18 water into the RCS to meet combined reactivity control system redundancy and capability requirements of GDC 26 and 27 as part of its primary review responsibility for SRP Section 4.3. c. The Reactor Systems Branch (RSB SRXB ) reviews the CVCS flow capacity and 19 injection pressure to verify that specified acceptable fuel design limits are not exceeded following 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. d. RSBThe SRXB also reviews CVCS malfunctions that can result in a decrease in 20 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 DRAFT Rev. 3 - April 1996 9.3.4-4 the shutdown margin has been eliminated as part of its primary review responsibility for SRP Section 15.4.6. 3. The Emergency Preparedness and Radiation Protection Branch (PERB) performs the following reviews: a. The process and effluent radiological monitoring aspects of the CVCS are reviewed in SRP Section 11.5 by the PERB as part of its primary review responsibility for that section.21 b. The Radiation Assessment Branch (RAB),PERB as part of its primary review 22 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. 4.
