rade. A volcanically induced flood was assumed to cause a domino-type failure of the three dams on the tributary B River from a volcanic eruption of Mt. D. The evaluation indicated such an event could cause the second most severe artificial flood that would reach the site. This event was estimated to produce a peak flow at the site of 2,800,000 cfs 80,000 m /s (2,800,000 cfs) and a water level of 39 feet 12-km (39-ft) MSL, 11 3 26 27 feet 3 m (11 ft) below plant grade. 28 2.4.4-7 DRAFT Rev. 3 - April 1996 The findings will address the envelope of site-related hydrologic parameters. These parameters should be representative of the most severe hydrologic characteristics likely to occur as a result of dam failure.29 For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff’s evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site interface requirements, and combined license action items that are relevant to this SRP section. 30 V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. This SRP section will be used by the staff when performing safety evaluations of license applications submitted by applicants pursuant to 10 CFR 50 or 10 CFR 52. Except in those 31 cases in which the applicant proposes 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 conformance with Commission regulations. The provisions of this SRP section apply to reviews of applications docketed six months or more after the date of issuance of this SRP section.32 Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced regulatory guides.
