purious operations that have not been fully mitigated or eliminated from further consideration, the consequences of spurious operation of safety-related or NSR components are bounded by the acceptance criteria defined in the FSAR or the LAR. b. For each AOO in the design basis that occurs concurrently with the CCF, the plant response, calculated using realistic or conservative assumptions, does not result in radiation release exceeding 10 percent of the applicable siting dose guideline values, or in violation of the integrity of the primary coolant pressure boundary. c. For each PA in the design basis that occurs concurrently with each single postulated CCF, the plant response, calculated using realistic or conservative assumptions, does not result in radiation release exceeding the applicable siting dose guideline values, in violation of the integrity of the primary coolant pressure boundary, or in violation of the integrity of the containment. 4. Manual System-Level Actuation and Indications to Address Point 4 Point 4 of the NRC’s position on D3 states that the applicant shall provide a set of displays and controls in the MCR for manual system-level actuation of critical safety functions and monitoring of parameters that support the safety functions. Section B.1.2 defines critical safety functions. RG 1.62 outlines important design criteria for I&C equipment used by plant operators for manual initiation of protective actions. BTP 7-19-30 Revision 8 – January 2021 The reviewer should consider whether displays and manual controls provided to meet point 4 are not vulnerable to the same CCF as the proposed DI&C system. For example, the point at which the credited manual controls are connected to the safety equipment should be downstream of the equipment that can be adversely affected by a CCF. The reviewer should confirm that the applicant does not credit the same digital platform or analog technology for point 3 (e.g., to mitigate DBEs). Point 4 specifies that
