e SRXB reviews the postulated fuel failures resulting from overheating of cladding, overheating of fuel pellets, excessive fuel enthalpy, pellet/cladding interaction and bursting as part of its review responsibilities in Chapter 15.13 In addition, the SRXB will coordinate with other branches' evaluations that interface with the overall review of the system as follows: 1. The Mechanical Engineering Branch (EMEB) reviews the control rod drive mechanism design in SRP Section 3.9.4 and the reactor internals design in SRP Section 3.9.5.14 2. The Emergency Preparedness and Radiation Protection Branch (PERB) reviews the estimates of radiological dose consequences as part of its review responsibilities in Chapter 15.15 II. ACCEPTANCE CRITERIA Acceptability of the fuel system design as described in the applicant's safety analysis report (SAR) is based on regulations, general design criteria, regulatory guides, industry standards, and on independent calculations and staff judgements with respect to fuel system functions and component selections. The requirements relevant to the fuel system design are as follows:16 1. 10 CFR Part §50.46 as it relates to the cooling performance analysis of the emergency core cooling system (ECCS) using an acceptable evaluation model, and establishing acceptance criteria for light water nuclear power reactor ECCS.17 2. 10 CFR Part 100 as it relates to determining the acceptability of a reactor site based on calculating the exposure to an individual as a result of fission product releases to the environment following a major accident scenario.18 3. General Design Criterion 10 as it relates to assuring that specified acceptable fuel design limits are not exceeded during any condition of normal operation, including the effects of anticipated operational occurrences.19 4. General Design Criterion 27 as it relates to the reactivity control system being designed with appropriate margin, and in conjunction with the ECCS, being capable of controlling
