hes specific acceptance criteria for an ITAAC if it is decided that an ITAAC is needed. d. In addition to safety-related HSIs, the HFE reviews should include non-safety- related HSIs for the following reasons: • On integrated digital control systems, operators use the non-safety-related control system if it is available for responding to plant events. • Inconsistent HFE design between the non-safety systems and the safety systems could potentially increase error rates. The operator would have to use a different, infrequently used configuration on the safety-related components. • Alarm systems and large screen displays are non-safety-related systems providing significant input into command and control activities, event diagnostics, and operator situational awareness. 18.0-13 Revision 3 – December 2016 • Non-safety systems and functions can divert the operator’s attention. 3. Verification that the design conforms to HFE standards a. An acceptable approach is described in NUREG-0700. If the applicant/licensee has incorporated the HFE design into a simulator or mockup, consideration should be given to conducting observations of the simulator/mockup. Such observations provide for an efficient way to evaluate the design against the NUREG-0700 standards. b. Verify the interfaces described in Section I have been properly coordinated. The following practices have proven effective for DC reviews: • Contact the lead I&C reviewer and provide the HFE point of contact(s) for supporting the RG 1.97, evaluation and the evaluation of manual actions credited in the diverse actuation system (DAS) design. The RG 1.97 parameters may also be significant inputs into the SPDS and large display panel designs. The DAS manual actions are contained in the Chapter 7 application. The HFE evaluator usually provides a safety evaluation input on these manual actions which is embedded in the Chapter 7 safety evaluation. • Verify that the “important human actions” provided by the
