NUREG-1791, “Guidance for Assessing Exemption Requests from the Nuclear Power Plant Licensed Operator Staffing Requirements Specified in 10 CFR 50.54(m)” • NUREG/CR-6838, “Technical Basis for Regulatory Guidance for Assessing Exemption Requests from the Nuclear Power Plant Licensed Operator Staffing Requirements Specified in 10 CFR 50.54(m)” Attachment B provides additional guidance on evaluating workload In support of staffing level reviews. 5. Verification that HFE design effectiveness has been demonstrated in a performance-based integrated system validation test. a. Verification that a design meets applicable HFE design criteria provides assurance that the individual design elements (e.g., individual controls, indications, alarms) support performance of discrete tasks (e.g., reading a gauge) but such verifications provide only limited assurance that collectively the elements of an HSI will constitute an effective integrated system in which these elements can be used in concert to support complex operator performance (e.g., mitigate a steam generator tube rupture). Therefore an integrated system validation (ISV) is used to validate the design effectiveness. Where feasible, the ISV should be subject to an inspection or audit to verify the HFE design supports the operator actions being credited in the licensing documentation. b. Because the ISV depends on operator programs (i.e., procedures, training), the ISV may sometimes be submitted at the implementation plan level with performance of the ISV tracked as an ITAAC consistent with the position described in SECY 92-053. In this case, the implementation plan must contain specific acceptance criteria describing how the ISV will be performed. The acceptance criteria should be identified as Tier 2* information. c. In the case of operating reactors, the ISV must be complete prior to implementation of the proposed action or program. In the rare cases when this cannot be done, such as when the simulator
