the procedures are also used to verify that the initial design criteria and bases have been appropriately implemented in the final design set forth in the final SAR. The COL and DC review also include the proposed technical specifications to assure that they are adequate in regard to limiting conditions of operation and periodic surveillance testing. Upon request from the primary reviewer, other staff will provide input for the areas of review stated in Subsection I. The primary reviewer obtains and uses such input as necessary to assure that this review is complete. For DC and COL applications submitted under Part 52, the level of information reviewed should be consistent with that of a FSAR submitted in an OL application. However, verification that the as-built facility conforms to the approved design is performed through the ITAAC process. 1. Using the ICS operating criteria specified in the applicant’s SAR (or DCD), the reviewer confirms that the ICS can maintain coolant inventory in the reactor vessel and remove reactor decay heat following shutdown and isolation, thereby keeping the core covered and assuring cladding integrity. This determination is based on engineering judgment and independent calculations (where deemed necessary), using information as specified in items 2 and 3 below. The reviewer verifies that the decay heat loads used in the ICS analyses are applicable and consistent with SRP Section 4.2. 2. Using the description of the ICS given in the applicant’s DCD, including component lists and performance specifications, the reviewer determines that the ICS piping and instrumentation will allow the system to operate as intended. This is accomplished by reviewing the process and piping and instrumentation diagrams (P&IDs) to confirm that piping arrangements permit the required flowpaths to be achieved and that sufficient process sensors are available to measure and transmit necessary information. 5.4.13-12 March 2007 3.
