should be identified and | explained. | C. Specific information on the actual SSCs within the scope of the MR program will | be reviewed as part of the operational program implementation inspection by the NRC, including, for each SSC in scope, the following: i. Specific MR requirement(s) in 50.65(b) that require the SSC to be in scope. ii. For each SSC, for each 50.65(b) scoping criterion, the function(s) that require the SSC to be in scope. iii. For each SSC, for each 50.65(b) scoping criterion, as applicable, the failure modes and effects that require the SSC to be in scope. iv. For each SSC scoping function or vulnerability, the functional performance requirements/success criteria and/or functional failure definitions and implications. D. The applicant’s submittal should describe the process for determining the | safety/risk significance classification of SSCs within the scope of the MR program, including risk metrics/importance measures and values, operating | experience, vendor information, RAP scope (modified for the operations phase | as necessary), and any other factors considered by the expert panel. The MR | program description should address the criteria for risk ranking of passive | components in the new plant designs, especially if it involves a deviation from NUMARC 93-01 and RG 1.160. E. If the applicant proposes to credit its MR program (along with its QA, testing, | surveillance and underlying maintenance programs) when implementing the RAP in the operations phase, the applicant should include a description of how the RAP SSCs (as identified in SRP Section 17.4) will be included in the MR program scope and also included in the high-safety-significant (HSS) category. In addition, the process controlling how the RAP SSC list may be modified by | site-specific requirements and information (e.g., SSCs included in the EOPs) should be described. Because not all modifications, if any, to the RAP list are expected to be available at the time of the COL
