4A suitable part-task simulator is one of demonstrated scope and fidelity sufficient for the conduct of the specific validation. 18-A-7 Rev. 0 – November 2009 information presented in the documented sequence of manual operator actions should be compatible with the minimum number, qualifications, training, and experience of the operating staff. Operators and system technical experts should ensure that the documented sequence of manual operator actions, independent of the time required, is technically correct and will achieve the desired technical result(s). These personnel should verify the documented sequence of manual operator actions is supported by the existing or planned displays and controls to be used by the operator. Walkthrough/talkthrough of planned displays and controls for new plants should be conducted to the extent practical, according to the state of the design and supplemented as necessary by use of such aids as arrangement diagrams, vendor drawings, and panel fabrication drawings. Results should be documented in the D3 analysis for NRC review. Preliminary validation results should be such that there is high confidence that the time required for manual operator actions will satisfy the success criteria for the integrated system validation described below. Unacceptable preliminary validation results should result in modification of the D3 coping strategy. Modification of the D3 coping strategy will require re-analysis, re-validation and re-submittal for NRC staff review. If a successful manual action strategy cannot be achieved, diverse automation is required. When the vendor/applicant believes that the analysis provides high confidence that the time required for operator action will satisfy the success criteria for integrated systems validation, the complete D3 analysis, which provides time available and time required, and the supporting analyses, is submitted for NRC review. This D3 analysis will be submitted as part of the supporting justification
