Content:
o the time available (per defense-in-depth analysis results) and previous estimates of time required. The digital I&C system timing analysis results in support of determining the time available should be validated as necessary by testing on integrated digital I&C systems and components. 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 defense-in-depth coping strategy. Modification of the defense-in-depth coping strategy would require reanalysis, re-validation and re-submittal for NRC staff review. If a successful manual action strategy cannot be achieved, diverse automation is required. 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 defense-in-depth analysis, which provides time available and time required, the supporting analyses, which provides time available and time required, and validation results shall be submitted to the NRC for verification of ITAAC closure or completion of the License Condition. 3.B. Review Criteria The responsible reviewers evaluate vendor/licensee/applicant’s submittals for compliance with the following criteria: General • The ISV is completed as part of the HFE program that is implemented in accordance with NUREG-0711.
