iminary validation results should provide high confidence that the performance time criteria will be met in the Phase 3, ISV. Unacceptable ISV results will require modification of the defense-in-depth coping strategy late in the design and licensing process. 18.0-23 Draft Revision 3 – July 2015 licensee/applicant should measure operator response times (performance times) of all operating crews in representative event simulations. Performance times should be compared to the time available (per the event analysis results) and previous estimates of time required. In selecting personnel for event simulations, consideration should be given to the assembly of both nominal and minimum crew configurations, including shift supervisors, reactor operators, shift technical advisors, etc., that will participate in the validation tests. The composition of operations personnel need only include personnel who are relevant to the credited actions. Acceptable validation results will provide the basis for meeting the NRC’s design certification, license application or amendment request approval requirements. Unacceptable validation results will require modification of the design strategy. Modification of the design strategy would require reanalysis, re-validation and re-submittal for NRC staff review. If a successful manual action strategy cannot be achieved, automation should be considered. The ISV shall be implemented and documented as an ITAAC item or license condition for plants licensed under 10 CFR Part 52 or as a license condition for operating plants that have not upgraded the plant-referenced simulator in advance of the control room modifications. The complete analysis, which provides time available and time required, the supporting analyses and validation results shall be submitted to the NRC for verification that the credited manual action supports the design assumptions. 3.B.
