ubject to appropriate training. d. The manual controls for critical safety functions are at the system or division level and are located within the MCR. For plants licensed to allow one division to be continuously out of service, the diverse manual actuation applies to at least one division that is in service. e. If equipment that is not safety related is used, its quality and reliability are adequate to support the manual operator action during the associated event conditions. f. The displays and controls are independent and diverse from (i.e., unlikely to be subject to the same CCF as) the equipment performing the same functions within the proposed DI&C systems. These displays and controls are not adversely affected by postulated CCFs that could disable the corresponding functions within the proposed DI&C systems. For applications that propose a different approach for meeting Point 4, acceptance criteria a, c, e, and f above are generally applicable regardless of the location of the equipment performing specific critical safety functions. These criteria are likely to be relevant to most applications. If an application proposes a different approach that does not meet all of the acceptance criteria above (i.e., items a–f), the reviewer should determine whether the application contains appropriate justification to show that the plant design yields a level of safety commensurate with that provided by ensuring that operators’ ability to actuate the applicable critical safety functions and monitor and control the related parameters is maintained. 5. Information for Interdisciplinary NRC Staff Review BTP 7-19-36 Revision 9 — May 2024 In addition to conducting the review described in the preceding sections, the I&C technical reviewer should also work with NRC staff in other disciplines to identify other areas that may be affected by CCFs. The I&C technical staff should review the following for potential interdisciplinary concerns:  the applicant’s documentation
