ated scope and fidelity sufficient for the conduct of the specific validation. 18.0-23 Revision 3 – December 2016 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 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 design strategy. If successful manual actions cannot be achieved, automation should be considered. 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 analysis, which provides time available and time required, and the supporting analyses, is submitted for NRC review. This analysis will be submitted as part of the supporting justification for a DC, DC amendment, COL application, or license amendment. When the NRC reviewers have high confidence that the manual operator actions will be accomplished correctly, reliably, and within the time available, the NRC staff will make a safety determination as part of the safety evaluation report (SER) on the associated licensing action. Acceptable implementation shall be verified
