NRC-issued license to operate a commercial nuclear reactor of the same type (i.e., pressurized water reactor or boiling water reactor) for which the design is being validated. • Actions allocated to non-licensed operators are validated using non-licensed personnel trained in accordance with a program that meets the requirements of 10 CFR 50.120. • The MCR operating staff size and composition used in the event simulations are the same as was used for the analysis and preliminary validation. • All crews are included as part of the ISV. For vendor/applicants using the 10 CFR Part 52 process the minimum number of crews should be established in accordance with the guidance of NUREG-0711 (e.g., as specified in the vendor’s/applicant’s NRC- approved integrated system validation implementation plan). Procedures • The manual operator actions to be credited in the event analysis are directed by procedure steps included within procedures and executed from the MCR. Operational Conditions Performance Times • For each manual action, the mean performance time of the crews is less than or equal to the estimated time required derived from the analysis phase. • For each manual action, the performance time for each crew, including margin determined in the time required analysis, is less than the analyzed time available. 18.0-25 Draft Revision 3 – July 2015 PHASE 4: MAINTAINING LONG-TERM INTEGRITY OF CREDITED MANUAL ACTIONS 4.A. Method Among other factors, changes in plant design, procedures, and operator training can affect the ability of operators to correctly and reliably perform manual actions. Accordingly, the licensee/applicant should establish a strategy for long-term monitoring of operator ability to reliably perform the manual operator actions credited in an event analysis. The scope of the performance monitoring strategy should provide adequate assurance that integrated system performance will be maintained within the bounds established by the ISV and
