Content:
h ground levels would 2.4.5-4 Rev. 2 - July 1981 limit wave heights in the vicinity of exposed safety-related buildings, except the service water intake, to 1.6 feet. For the intake, the applicant has estimated waves 3 feet high. The result- ing wave runup levels were estimated to reach a maximum elevation of 28.3 feet MSL on the intake, and 25.6 feet MSL on other exposed buildings. The staff concludes that the plant design meets the requirements of General Design Criterion 2 and 10 CFR Part 100 with respect to surge and seiche flooding. The bases for this conclusion is that the intake structure and the other exposed plant buildings are designed to with- stand wave runup to 29.0 feet MSL and 26.0 feet MSL respectively, which are above the maximum calculated wave runup levels discussed above. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alterna- tive method for complying with specified portions of the Commission's regula- tions, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced regulatory guides. VI.
