tem, the reviewer would adjust the review procedures given below. However, the system design would be required to meet the acceptance criteria given in subsection II of this SRP section. 1. The SAR is reviewed to determine that the system description and piping and instrumentation diagrams (P&IDs) delineate the SLCS equipment. The reviewer, using the results of failure modes and effects analyses, compari- sons with previously approved systems, or independent calculations, as appropriate, determines that the system can sustain the loss of any active component and meet the minimum system requirements for the safe shutdown and accident mitigation. The system P&IDs, layout drawings, and component descriptions and characteristics are reviewed to determine the following: 9.3.5-3 Rev. 2 - July 1981 a. The SLCS is classified Quality Group B and seismic Category I. Component and system descriptions in the SAR are reviewed by the ASB to verify that the above classifications have been included, and the P&IDs should indicate any points of change in piping quality group classification. The review for seismic design is performed by the SEB and the review for seismic and quality classification is performed by the MEB as indicated in subsection I of this SRP section. b. Design provisions have been made that permit appropriate inservice inspection and functional testing of the system. It will be accep- table if the SAR information delineates a testing and inspection program and if the system drawings show the connections and special piping and equipment required by this program. c. Using the results of the evaluation performed by the Core Performance Branch, the ASB determines that the system has the capability to store the required quantity of neutron absorber in solution and that the injection rate is sufficient to bring the reactor from rated power to cold shutdown at any time in core life with the control rods remain- ing withdrawn in the rated power pattern, taking into account
