sses applications that propose that the consequences of a residual identified CCF remain acceptable. For such applications, the reviewer should consider whether the applicant’s analysis demonstrates that, should the CCF occur, the facility will remain within the acceptance criteria defined in the FSAR or the LAR for the limiting events applicable to the proposed DI&C system. For each event considered in the accident analysis, the applicant may perform the D3 assessment using either best-estimate methods (i.e., using realistic assumptions to analyze the plant’s response to DBEs) or conservative methods (i.e., design-basis analysis). The reviewer should consider whether the D3 assessment shows that the consequences of potential CCFs of the proposed DI&C system are acceptable. Acceptance Criteria for Determination of Acceptable Consequences If the following acceptance criteria are met, the reviewer should conclude that the application shows that the consequences of potential CCFs of the proposed system are acceptable: a. For those postulated spurious operations that have not been fully mitigated or eliminated from further consideration, the consequences of the spurious operation 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 either in radiation release exceeding 10 percent of the applicable dose guideline values, or in a loss of 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 dose guideline values, in violation of the integrity of the primary coolant pressure boundary, or in violation of the integrity of the containment. 3.4 Risk-Informed
