ther 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 of its safety-significance determination for a proposed DI&C system and the supporting technical basis, with risk analysts reviewing the details of a risk-informed approach or risk insights supported by a plant-specific PRA if used in the D3 assessment  the results of any D3 assessment, including consideration of spurious operations, and specifically the following: – any means used to eliminate potential CCFs from further consideration, any information demonstrating that these means are effective, and any remaining CCF vulnerabilities (residual risks) – any diverse means provided by the applicant to accomplish a function that is the same as or different from the safety function disabled by a postulated CCF, for any CCFs not eliminated from further consideration using design attributes; also, the information provided to demonstrate the effectiveness of any diverse means credited to mitigate the potential CCF, including the results of HFE analysis for any manual operator actions used as diverse means – verification of the acceptability of the results of any consequence analysis that the applicant has performed for CCFs not eliminated from further consideration or mitigated using diverse means, with such analyses demonstrating that the consequences of the CCFs are within acceptable limits for each AOO and PA  for systems that the applicant has not assessed for CCF, information showing that all conditions introduced by the proposed modification are bounded by the acceptance criteria defined in the FSAR or the LAR for the limiting events applicable to the proposed DI&C system  for manual system-level actuation and indications to address Point 4, design information showing the following: – Controls and displays are provided in the MCR to perform manual
