logic conditions for minimum heat transfer and for performing the tran- sient analysis for cooling ponds and spray ponds are provided in References 24 and 25, respectively. IV. EVALUATION FINDINGS The findings will indicate the degree of compliance with GDC 2, GDC 44, 10.CFR Part 100, and 10 CFR Part 100, Appendix A. [ For construction permit (CP) reviews the findings will summarize the applicant's and staff's estimates of the design basis minimum water flows and levels. If the applicant's estimates are no more than 5% less conservative than the staff's estimates, staff concurrence in the applicant's estimates will be stated. If the applicant's estimates are more than 5% less conservative and if the proposed plant may be adversely affected, a statement of the staff's position (bases) will be made. A similar finding on the design bases for the ultimate heat sink will be made. If technical specification requirements are needed to assure an adequate supply, they will be indicated in the CP statement and required for operation. For operating license (OL) reviews of plants. for which detailed low water reviews were done at the CP stage, the CP conclusions will be referenced. In addition, the results of a review to reaffirm the low water design bases will be noted. If no changes have been made to the ultimate heat sink design since the CP review, the conclusions of the CP will be referenced. However, for both the low water considerations and the ultimate heat sink, an evaluation will be made during the OL review to assure that the design bases have been properly implemented. The availability of long-term water supply will be noted. If no low water and ultimate heat sink review was undertaken at the CP stage (of the scope described), this fact will be noted also. A sample CP-stage statement follows: The normal water supply for the station will be obtained from Lake A. Emergency cooling water will be furnished by the ultimate heat sink reservoir which is not dependent upon
