dressed and the sources of radionuclides that were screened out.” As noted above and in Appendix A, item 1, of this document, the staff is developing guidance related to PRA that, if approved, would Appendix B provides supplemental guidance for PRA preparation at the CP stage. DG-1404, Revision 1, Page 17 e. Clarification: Section C.2.1.1 of NEI 21-07 states that “At the CP stage, neither the plant design nor the PRA is expected to have the level of maturity that will be necessary to support an OL application. At the CP application stage, the applicant should describe its ultimate intended approach for qualifying the PRA. If conformance to ASME/ANS RA-S-1.4-2021 is planned, a simple statement to that effect should be sufficient.” The “simple statement” is only regarding the commitment to conform to ASME/ANS RA-S-1.4-2021 at the OL stage. The description or a summary of PRA in a CP application, however, is broader than a simple commitment to the standard. As noted in NEI 21-07, a CP applicant should describe the attributes of the PRA in the application. In addition to these attributes, as amended by position C.3.d above, the CP application should also discuss topics such as the PRA’s conformance to RG 1.247 for trial use, and NEI 20-09, if a peer review is performed at the CP stage. f. Clarification: Section C.2.1.1 of NEI 21-07 states that “Note: This guidance document does not address SAR content for a PRA that has not been peer reviewed using the non-LWR PRA standard. In such an instance, the information to be provided on the PRA, either in the SAR or other documentation, may be more extensive than the guidance provided herein.” NEI 21-07, Revision 1, however, addresses the SAR content for a CP application for which no peer review has been performed; accordingly, this Note should be applied only to SAR content for applications other than a CP application. g. Addition: In addition to the site information described in Section C.2 of NEI 21-07,
