on area and to the low population zone boundaries for the (INSERT.PLANT NAME) site, in conjunction with the operation of the dose mitigating ESF systems, are sufficient to provide reasonable assurance that the calculated radiological consequences of a postulated control rod drop accident are well within the exposure guidelines as set forth in 10 CFR Part 100, paragraph 11. The staff conclusion is based upon (1) its review of the applicant's analysis of the accident and radiological consequences and (2) the staff review of the same accident for similar plants at a number of sites using the source term assumptions of Regulatory Guide 1.77 and upon the similarity of those plant features for the (INSERT PLANT NAME) which affect the radiological consequences of the rod drop accident. Where the radiological consequences have been calculated, the findings may be of the following form: The staff concludes that the distances to the exclusion area and to the low population zone boundaries for the (INSERT PLANT NAME) site, in conjunction with the operation of the dose mitigating ESF systems, are sufficient to provide reasonable assurance that the calculated radiological consequences of a postulated control rod drop accident are well within the exposure guidelines as set forth in 10 CFR Part 100, paragraph 11. The staff conclusion is based upon (1) its review of the applicant's analysis of the accident and radiological consequences and (2) an independent dose calculation by the staff using the source term assumptions contained in Regulatory Guide 1.77, the atmospheric dispersion factors as discussed in SRP Section 2.0, and other conservative assumptions. V. IMPLEMENTATION The following provides guidance to applicants and licensees regarding the staff's plans for using this appendix to SRP Section 15.4.9. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method
