Review Interfaces10 A secondary review is performed by the RSB SRXB, and the results are used by AEB PERB in the overall evaluation of the MSLB radiological consequence analysis. The potential for fuel failures resulting from the postulated MSLB accident is routinely evaluated by the RSBSRXB under SRP Section 15.1.5, and the results will be provided to the AEB PERB as an additional source of radioactive iodine activity in the reactor coolant for consideration in the evaluation of 11 the MSLB radiological consequences. The review of the technical specifications is coordinated with and performed by the Licensing Guidance Branch Technical Specifications Branch (TSB) as part of its primary review 12 responsibility for SRP Section 16.0. The acceptance criteria necessary for the review and the methods of application are contained in the referenced SRP section. II. ACCEPTANCE CRITERIA The acceptance criteria are based on the relevant requirements of 10 CFR Part 100 as related to the radiological consequences of a postulated accident. The plant site and the dose mitigating engineered safety features are acceptable with respect to the radiological consequences of a postulated MSLB outside containment of a PWR facility if the calculated whole-body and thyroid doses at the exclusion area and the low population zone outer boundaries do not exceed the following exposure guidelines: 1. For an MSLB with an assumed preaccident iodine spike and for an MSLB with the highest worth control rod stuck out of the core, the calculated doses should not exceed the guideline values of 10 CFR 100.11; Part 100., Section 11 (Ref. 1), and 13 2. For an MSLB with the equilibrium iodine concentration for continued full power operation in combination with an assumed accident initiated iodine spike, the calculated doses should not exceed a small fraction of the above guideline values, i.e., 10 percent% or 25 mSv (2.5 rem) and 0.3 Sv (30 rem), respectively, for the whole-body 14
