Content:
f the postulated fission product release would not receive a radiation dose in excess of 25 rem TEDE, and; • An individual located at any point on the outer boundary of the LPZ who is exposed to the radioactive cloud resulting from the postulated fission product release (during the entire period of its passage) would not receive a radiation dose in excess of 25 rem TEDE. (2) Option 2: Use the greater of the dose consequence results from the bounding DBA and from a bounding BDBE, as identified in the LMP-based approach, to establish the acceptability of the EAB and LPZ. The uncertainty analyses for the mechanistic source terms and radiological doses should be described as part of the evaluation of conservative assumptions used in the analysis. This option provides an acceptable approach to compliance with 10 CFR 50.34 and 10 CFR 52.79 that precludes the need for an exemption from these requirements, as long as the bounding BDBE involves or bounds an event sequence meeting the description of a major accident and the offsite consequences are below the reference values for public dose in 10 CFR 50.34(a)(1)(ii)(D)(1) or 10 CFR 52.79(a)(1)(vi)(A) for the EAB and those in 10 CFR 50.34(a)(1)(ii)(D)(2) or 10 CFR 52.79(a)(1)(vi)(B) for the LPZ. d. Addition: Section C.2.1.1 of NEI 21-07, Revision 1, “Overview of PRA,” includes a subsection titled, “Two-Step Licensing (CP Content).” This section notes that as part of a CP application the “applicant should address the last five items in the Section 2.1.1 list, consistent with the state of the plant design and the PRA at the time of the CP application.” In addition to these five items, the application should include the item in the Section C.2.1.1 list labeled, “Identification of the sources of radionuclides addressed 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
