CFR Title: 

Content:
We have evaluated the performance of the proposed cooling pond and conclude that, under meteorological conditions of the severity described in Regulatory Guide 1.27, (1) the design will provide suffi- cient water in the pond to cool the plant for at least 30 days without any makeup and (2) the maximum temperature of the water supplied to the plant will be below the design temperature of 1100 Fahrenheit. Based upon the evaluations described above, we conclude that the cooling water supply for the plant meets the requirements of General Design Criterion 2, 10 CFR Part 100, and 10 CFR Part 100, Appendix A 2.4.11-7 Rev. 2 - July 1981 with respect to hydrologic characteristics and that it meets the requirements of General Design Criterion 44 with respect to thermal aspects of the heat transfer system. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regard- ing the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposed an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein-will be used by the staff in its evaluation of con- formance with Commission regulations. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced regulatory guides and NUREGs. VI.
