Content:
ify that the initial design criteria and bases have been appropriately implemented in the final design as set forth in the final safety analysis report (FSAR). These procedures are used during a DC or COL review. The procedures for review of OL and COL applications include a determination that the content and intent of the technical specifications prepared by the applicant are in agreement with the requirements for system testing, minimum performance, and surveillance, developed as a result of the technical specifications review, as indicated in subsection I of this SRP section. The primary reviewer will coordinate this review with the other staff as stated in subsection I of this SRP section. The primary reviewer obtains and uses such input as required to ensure that this review procedure is complete. The reviewer selects and emphasizes material from this SRP section as may be appropriate for a particular case. 1. The SAR is reviewed to determine that the system description and piping and instrumentation diagrams (P&IDs) delineate the system and components. 2. The SAR is reviewed to verify that the system design bases and an evaluation of the system capacity are provided, including the relation between the TBS capacity and relief 10.4.4-6 Revision 3 - March 2007 valve capacity in terms of percentage of rated main steam flow, the maximum reactor power step change the system is designed to accommodate without a reactor or turbine trip, and the maximum electric load step change the reactor is designed to accommodate without reactor control rod motion or steam bypassing. 3. TBS lines and other TBS components in BWR plants that do not incorporate an MSIVLCS and that take credit for fission product holdup and plateout in the TBS are reviewed for compliance with the applicable SRP acceptance criteria of Subsection II of this SRP. 4. The reviewer uses engineering judgment and the results of failure modes and effects analyses to determine that: A. Failure of the TBS to
