s evaluation process, such as the process outlined in NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition” (SRP), Chapter 18, “Human Factors Engineering,” should show that the proposed manual operator actions are both feasible and reliable. The reviewer may use a risk-informed approach to determine the appropriate level of HFE review needed for proposed changes to existing credited manual actions or for proposed new manual operator actions. The reviewer should consider whether the equipment necessary to perform these actions, including the supporting indications and controls, is diverse from (i.e., unlikely to be subject to 10 IEEE Std 279-1968, IEEE Std 279-1971, and IEEE Std 603-1991 require that certain manual controls or means of manual initiation be of the same quality as the protection or safety systems; SRM-SECY-22-0076 does not eliminate these regulatory requirements. However, other means of manual control or initiation may not need to be of the same quality. BTP 7-19-26 Revision 9 — May 2024 the same CCF as) the equipment performing the same function within the DI&C system. For example, the point at which the credited manual controls are connected should be downstream of the equipment that can be adversely affected by a CCF. If the equipment used to perform the credited manual operator action is not safety related, then the applicant should demonstrate that the equipment is of adequate quality. If the applicant has proposed the use of equipment outside the MCR to perform the credited manual operator action, the reviewer should consider whether this equipment is vulnerable to the same CCF as the DI&C system and whether the applicant has demonstrated that the equipment will be reliable, available, and accessible under the postulated event conditions. The reviewer may use the HFE principles and criteria identified in SRP Chapter 18 to evaluate the applicant’s selection and design of the
