fety goals which are supported by two quantitative objectives. Consistent with the safety goal policy statement, PRA is an acceptable tool for assessing conformance with the underlying purposes of the safety goals. 2. The advanced reactor policy statement notes that the Commission has issued a policy statement on “Severe Reactor Accidents Regarding Future Designs and Existing Plants” (50 FR 32138; August 8, 1985) (Ref. B-12), which indicates, in the context of the decision process for certifying a new standard plant design, that a new design can be shown to be acceptable for severe accident concerns, in part, by completion of a PRA and consideration of the severe accident vulnerabilities the PRA exposes along with the insights it may add to the assurance of no undue risk to public health and safety. 2 An ongoing rulemaking effort, “Incorporation of Lessons Learned from New Reactor Licensing Process (10 CFR Parts 50 and 52 Licensing Process Alignment),” Docket NRC-2009-0196, RIN-3150-AI66, includes proposed PRA-related requirements for 10 CFR Part 50 CP and OL applications that are similar to the existing PRA-related requirements for 10 CFR Part 52 licenses, certifications, and approvals. Further information about this rulemaking (including the proposed schedule) is available at https://www.nrc.gov/reading-rm/doc-collections/rulemaking- ruleforum/active/ruledetails.html?id=27. DG-1404, Revision 1, App. B, Page 4 3. The advanced reactor policy statement indicates the use of PRA as a design tool is implied by the Commission’s policy statement on “Use of Probabilistic Risk Assessment Methods in Nuclear Regulatory Activities” (60 FR 42622; August 16, 1995) (Ref. B-13). Implementation of the LMP methodology inherently conforms to the underlying purposes of these Commission policies. Supporting Risk-Informed Applications of the PRA in Addition to an Initial Licensing Application CP applicants may use the PRA to support risk-informed applications, in addition
