mission or commission that are plausible considering applicable operating experience and a human reliability analysis for the task. 18-A-5 Rev. 0 – November 2009 1.B. Review Criteria The responsible reviewers evaluate vendor/licensee/applicant’s submittals for compliance with the following criteria: • The analysis establishes the time available using an analysis method and acceptance criteria consistent with the guidance of BTP 7-19. The basis for the time available is documented. • The analysis of the time required is based on a documented sequence of operator actions (based on task analysis, vendor-provided generic technical guidelines for emergency operating procedure development, or plant-specific EOPs, depending on the maturity of the design). • Techniques to minimize bias are used when estimates of time required are derived using methods that are dependent on expert judgment. Uncertainties in the analysis of time required are identified and assessed. • The sequence of actions uses only alarms, controls, and displays that would be available in the MCR and operable during the assumed CCF scenario(s), as documented in the Failure Modes and Effects Analysis. • The estimated time for operators to complete the credited action is sufficient to allow successful execution of applicable steps in the symptom/function-based EOPs. • The initial MCR operating staff size and composition assumed for the analysis of time required is the same as the minimum MCR staff defined in the plant’s Technical Specifications. • If credited manual actions require additional operators beyond the Technical Specification minimum crew, the justification for timely availability of the additional staffing is provided and the estimate of time required includes any time needed for calling in additional personnel. • The analysis of the action sequence is conducted at a level of detail sufficient to identify individual task components, including cognitive elements such as
