ated as risk significant for the COL holder during the construction stage is appropriately revised; and verification that dominant failure modes consider any changes to site-specific elements, any new industry experience and analytical models. The NRC will verify the COL holder's implementation of the D-RAP by conducting NRC inspections and audits of the COL holder's ITAAC process as well as NRC inspections and audits of SSCs during the design, procurement, fabrication, construction and pre-operational testing phases of plant life prior to fuel load.3 4. Reliability Assurance during Operation. Operational reliability assurance activities are integrated into other programs (e.g., maintenance, surveillance, inservice inspection, inservice testing, and quality assurance). Many operational reliability assurance activities may be integrated into those required by 10 CFR 50.65 ("the maintenance rule"), which includes performance and condition monitoring requirements for safety-related and risk-significant non-safety-related SSCs. Appropriate and effective integration of operational reliability assurance activities 17.4-5 DRAFT Rev. 0 - April 1996 required by the maintenance rule will help to mitigate accidents or transients or prevent inadvertent reactor scrams or safety system actuations. Other operational reliability assurance activities for safety-related SSCs may be incorporated into the quality assurance program developed to implement Appendix B to 10 CFR Part 50 and into programs for surveillance, inservice inspection, and inservice testing. The objectives of operational reliability assurance activities will be met if the licensee's administrative processes and procedures include a requirement to determine the cause of failures and to specify corrective actions for non-safety-related, risk-significant SSCs. The COL holder should be given maximum flexibility in seeking the best approach to implement this RAP requirement. The following is one acceptable approach;
