core design, and the steady state analysis of the core thermal-hydraulic performance.* The review concentrated on the differences between the proposed core design (and criteria) and those designs and criteria that have been previously reviewed and found acceptable by the staff. It was found that all such differences were satisfactorily Justified by the applicant. The applicant's thermal-hydraulic analyses were performed using analytical methods and correlations that have been previously reviewed by the staff and found acceptable. For a CP, the following conclusions should be made: The staff concludes that the thermal-hydraulic design of the core meets the requirements of General Design Criterion 10, 10 CFR Part 50. The core has been designed with appropriate margin to assure that acceptable fuel design limits are not exceeded during steady-state operation or anticipated operational occurrences. This conclusion is based on the applicant's analyses of the core thermal-hydraulic performance which was reviewed by the staff and found to be acceptable. The applicant will establish a preoperational and initial startup test program in accordance For an OL review this sentence should be modified to include the implementation of the design criteria as represented by the final core design. 4.4-7 Rev. 1 - July 1981 with Regulatory Guide 1.68 to measure and confirm the thermal-hydraulic design aspects. The loose parts and vibration monitoring system is designed for compliance with the requirements of Regulatory Guide 1.133 and the instrumentation for the detection of inadequate core cooling is in compliance with the requirements of item II.F.2 of NUREG-0718. For an OL application, the following types of conclusions should be supported. The staff concludes that the thermal-hydraulic design of the core meets the requirements of General Design Criterion 10, 10 CFR Part 50 and is acceptable for final design appoval. We also conclude that the reactor core has been design with
