ecific PRA for a combined license, respectively. SRP Section 19.0 also provides guidance for reviewing DI&C system risk assessments for new reactors.  SRP Section 19.1, “Determining the Technical Adequacy of Probabilistic Risk Assessment for Risk-Informed License Amendment Requests after Initial Fuel Load,” provides review guidance for assessing the technical adequacy of a baseline PRA used to support license amendments for operating reactors, as well as LARs submitted after initial fuel load for new reactors.  SRP Section 19.2, “Review of Risk Information Used to Support Permanent Plant-Specific Changes to the Licensing Basis: General Guidance,” provides review guidance for PRAs used by licensees or applicants to support licensing applications.  Design Certification / Combined License (DC/COL)-ISG-028, “Assessing the Technical Adequacy of the Advanced Light-Water Reactor Probabilistic Risk Assessment for the Design Certification Application and Combined License Application,” issued November 2016, provides review guidance for assessing the technical adequacy of the PRA needed for either a design certification application under 10 CFR 52.47(a)(27) or a combined license application under 10 CFR 52.79(a)(46). Acceptance Criteria for Determining Consistency with NRC Policy and Guidance on Risk-Informed Decision-Making If the application meets the acceptance criteria in the applicable NRC staff review guidance for risk-informed applications and addresses the five principles of risk-informed decision-making in RG 1.174, the reviewer should conclude that the application is consistent with the established NRC policy and applicable guidance on risk-informed decision-making. 3.4.2 Modeling Common-Cause Failures It is important for reviewers to understand the limitations associated with some PRA models related to CCFs. One limitation is that some PRA models do not include details of the hardware or software components of DI&C systems or of all the
