determine that the design criteria and bases and the preliminary design as set forth in the preliminary safety analysis report meet the acceptance criteria given in subsection II of this SRP section. For the review of operating license (OL) applications, the procedures are also utilized to verify that the initial design criteria and bases have been appropriately implemented in the final design as set forth in the final safety analysis report. Upon request from the primary reviewer, the coordinating review branches will provide input for the areas of review stated in subsection I of this SRP section. The primary reviewer obtains and uses such input as required to assure that this review procedure is complete. For the purpose of this SRP section, a typical system is assumed for use as a guide. It is assumed that the SLCS consists of a boron solution tank, a test water tank, two positive displacement pumps, two explosive valves, and associated local valves and controls. For cases where there are variations from this system, 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, comparisons 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: 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
