onal 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 reactivity and cooling the core under post accident conditions. 20 DRAFT Rev. 3 - April 1996 4.2-4 5. General Design Criterion 35 as it relates to providing an emergency core cooling system to transfer heat from the reactor core following any loss of reactor coolant at a rate such that (1) fuel and clad damage that could interfere with continued effective core cooling is prevented and (2) clad metal-water reaction is limited to negligible amounts.21 Specific criteria necessary to meet the relevant requirements of 10 CFR Part 50, §50.46; General Design Criteria 10, 27, and 35; Appendix K to 10 CFR Part 50; and 10 CFR Part 100 identified 22 in subsection I of this SRP section are as follows: 23 A. Design Bases The fuel system design bases must reflect the four objectives described in subsection I, Areas of Review. To satisfy these objectives, acceptance criteria are needed for fuel system damage, fuel rod failure, and fuel coolability. These criteria are discussed in the following: 1. Fuel System Damage This subsection applies to normal operation, and the information to be reviewed should be contained in Section 4.2 of the Safety Analysis Report. To meet the requirements of General Design Criterion 10 as it relates to Specified Acceptable Fuel Design Limits for normal operation, including anticipated operational occurrences, fuel system damage criteria should be given for all known damage mechanisms. Fuel system damage includes fuel rod failure, which is discussed below in subsection II.A.2. In addition to precluding fuel rod failure, fuel damage criteria should assure that fuel system dimensions remain within operational tolerances and that functional capabilities are not reduced below those assumed in the safety analysis. Where applicable, the fuel damage criteria
