ional consensus standard, as endorsed by the NRC. Additionally, PRA self-assessments and peer reviews that follow an approved process should be used, as endorsed by the NRC, to demonstrate how the PRA meets the NRC-endorsed requirements in a national consensus standard. As discussed in Regulatory Position C.2.2 and its subsections, NEI 20-09, Revision 1, provides current industry guidance on self-assessments and peer review, which is endorsed in this RG. C.3.3 Application-Specific Acceptance Criteria and Guidelines Application-specific guidance documents identify the applicability of acceptance criteria or guidelines for a given application. Such guidance documents should address the PRA results needed to compare against the acceptance criteria or guidelines and how the comparison should be done. By following this guidance, an applicant or holder of a license, certification, or permit should be able to readily demonstrate the applicability of the application-specific acceptance criteria or guidelines inherent to the application. More broadly, the Commission articulated in its policy statement “Safety Goals for the Operation of Nuclear Power Plants” (51 FR 28044; August 4, 1986 as corrected and republished at 51 FR 30028; August 21, 1986) two qualitative safety goals, which are supported by two quantitative goals (i.e., the QHOs). These are discussed in Regulatory Position C.1.1 of this RG. The Commission’s Safety Goals RG 1.247, Page 63 policy statement expresses its views on the level of risks to the public health and safety that the nuclear industry should strive to meet for nuclear power plants. If the safety goals and QHOs are not already used as acceptance criteria or guidelines for a given application, the applicant or holder of a license, certification, or permit should demonstrate how the application meets them.
