fuel cladding, or interference with core cooling are unlikely to occur. 4. GDC 10 requires that the reactor core and its coolant, control, and protection systems be designed with appropriate margin to assure that specified acceptable fuel design limits are not exceeded during any condition of normal operation, including the effects of anticipated operational occurrences. Reactor internals perform safety functions, or might (through their failure) adversely impact the performance of safety functions, such as reactivity control and core cooling, essential for assurance that specified acceptable fuel design limits are not exceeded. Application of GDC 10 to the reactor internals provides assurance of an acceptable design with sufficient margin to ensure functionality and integrity during any condition of normal operation, including the effects of anticipated operational occurrences, to achieve a high likelihood of performance of these safety functions. Assured performance of these safety functions provides confidence that specified acceptable fuel design limits for reactivity control and core cooling are not exceeded, thus assuring the integrity of the fuel and its cladding. III. REVIEW PROCEDURES The NRC staff reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s justification that the proposed alternatives provide an acceptable method for complying with the relevant NRC requirements identified in Subsection II. 1. The configuration and general arrangement of all mechanical and structural internal elements covered by this SRP section are reviewed and compared to those of previously licensed similar plants. The applicant should demonstrate that any significant changes in design or operating conditions do not affect the comprehensive vibration
