Content:
lt from severe accidents, the reviewer should do the following: (1) Consult the reviewer (or review branch) for the IPE, the reviewer of Chapter 19 of the SAR, or the reviewer of 50.34(f) to determine if the information given in the ER on which the applicantGs analysis is based is appropriate; that is, whether the applicant properly assessed and depicted severe-accident sequences, core damage, severe-accident progression, containment response, release categories, and source terms. (a) In consultation with the reviewer of the IPE, Chapter 19 of the SAR or the reviewer of 10 CFR 50.34(f), determine whether an acceptable platform has been provided for assessing the environmental consequences of severe accidents. (b) Consider the IPEEE for the analysis of severe accidents resulting from external initiators and the corresponding source-term releases. (2) Consult with the reviewer for ESRP 2.5.1 and review other appropriate sources of demographic data to ascertain that sufficient population data were used for the applicant’s calculation of the population dose and that an appropriate population distribution was used. (3) Ensure that the dispersion data were determined from representative onsite meteorological data by coordinating your review with the reviewer of ESRP 2.7. (4) Ensure that estimates of the collective dose were made for the projected population within an 80-km (50-mile) radius. (5) Determine if the applicant appropriately extended the information on anticipated release classes and containment response to the calculation of dose consequences. (a) Evaluate the dose-consequence code to determine if the consequence code used by the applicant is currently supported by NRC for estimating the dose consequences associated with severe reactor accidents. October 1999 7.2-5 NUREG-1555 (b) If the applicant used a code not currently endorsed by the NRC, either evaluate the code that was used or determine the dose consequences resulting from selected severe accidents
