lowing: a. The SLCS is classified Quality Group B and seismic Category I. Component and system descriptions in the SAR are reviewed by the ASBSRXB to verify that 34 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 SEBECGB and the review for seismic and quality 35 classification is performed by the MEBEMEB as indicated in subsection I of 36 this SRP section. b. Design provisions have been made that permit appropriate inservice inspection and functional testing of the system. It will be acceptable 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. For new applications, the reviewer evaluates the SLCS design provisions to test motor-operated valves under design-basis differential pressure and the piping design provisions for full flow testing (at maximum design flow) of pumps and check valves, as applicable. In accordance with the staff's position described in SECY 93-087 (Reference 6), design features should support inservice valve tests under the maximum practicable differential pressure and flow when it is not practicable to achieve design-basis differential pressure during an inservice test. Where it is not practicable to conduct inservice pump testing at design flow and pressure, analysis to extrapolate to design pressure is permitted.37 DRAFT Rev. 3 - April 1996 9.3.5-8 c. Using the results of the evaluation performed under SRP Section 4.3 by the Core Performance Branch, the ASBSRXB determines that the system has the 38 39 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to bring the reactor from rated power to cold shutdown at any time in core life with the control rods remaining withdrawn in the rated power pattern, taking into account the
