APPENDIX A REVIEW RESPONSIBILITIES Primary - Accident Evaluation Branch (AEB) Secondary - Core Performance Branch (CPB) I. AREAS OF REVIEW The AEB review under this appendix to SRP Section 15.4.9 includes the following aspects of the postulated control rod drop accident for a boiling water reactor facility: 1. an examination of the plant response to the accident; 2. the release of fission products from the core to the environment via the turbine and condensers, as a result of the accident; and 3. the calculation of whole-body and thyroid doses at the exclusion area boundary (EAB) and the low population zone (LPZ) boundary due to the releases from the accident. A secondary review is performed by the CPB and the results are used by AEB in the overall evaluation of the accident analysis. The core response aspects of the accident are reviewed by the CPB. Verification of the applicant's calculation of the number of fuel rod failures and the amount of fuel reaching the melting temperature is provided by the CPB. II. ACCEPTANCE CRITERIA The acceptance criteria are based on the requirements of 10 CFR Part 100 as related to mitigating the radiological consequences of an accident. The plant site and dose mitigating engineered safety features are acceptable with respect to the radiological consequences of a postulated control rod drop accident if the calculated whole-body and thyroid doses at the exclusion area boundaries (EAB) and at the low population zone (LPZ) boundaries are well within th exposure guideline values in 10 CFR Part 100, paragraph 11 (Ref. 1). "Well within" is 15.4.9-5 Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants.
