Monticello Nuclear Generating Plant, Unit 1 Table 2. Reevaluated Flood Hazards for Flood-Causing Mechanisms for Use in the MSA Mechanism Stillwater Elevation Waves/
Runup Reevaluated Hazard Elevation Reference Note 2: Reevaluated hazard mechanisms bounded by the current design basis (see Table 1) are not included in this table Note 3: Reported values are rounded to the nearest one-tenth of a foot.
Local Intense Precipitation 935.8 ft NGVD29 Minimal 935.8 ft NGVD29 FHRR Section 2.1.2 & Tables 5 and 6 Note 1: The licensee is expected to develop flood event duration parameters and applicable flood associated effects to conduct the MSA. The staff will evaluate the flood event duration parameters (including warning time and period of inundation) and flood associated effects during its review of the MSA.
