Content:
The staff verifies that AC LCOs and completion times, if appropriate, are established such that the availability of each function provides reasonable assurance that RTNSS SSCs can meet their RTNSS R/A missions. The staff also verifies that surveillance requirements are established which provide an adequate level of support to ensure that component performance is consistent with its RTNSS R/A mission. Reviewers should assure that any support systems needed to establish the availability of a function have been identified and addressed with ACs. It is acceptable for support systems to simply 19.3-12 Revision 0 – June 2014 inherit the controls of the supported system. The reviewer considers the activities, including tests, performed to implement a surveillance requirement and confirms that SSC availability can be adequately determined with the surveillance requirement. Guidance Specific to DC and COL applications For review of a DC application, the reviewer should follow the above procedures to verify that the design set forth in the FSAR meets the acceptance criteria. DCs have referred to the FSAR as the design control document. The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV.
