The licensee evaluated the SONGS site specific environmental conditions in Section X of Calculation No. DSC-001 against the parameters established in the NUHOMS Final Safety Analysis Report (FSAR) and Certificate of Compliance #1029 technical specifications and found the ISFSI site to be bounded by the design parameters established by the NUHOMS FSA This included: tornados/high winds, flood, seismic events, snow/ice loading, tsunami, lightning, burial under debris, normal and abnormal temperatures, and fires/explosion The data used for the analysis was from the SONGS reactor facility Updated Final Safety Analysis Report (UFSAR) and supporting calculation The maximum tornado wind speed for the SONGS site was 260 mph which consisted of a 220 mph rotational speed and a 40 mph translational spee These values were below the NUHOMS design criteria of 290 mph rotational and 70 mph translationa The tornado pressure differential for a tornado at SONGS was pounds/square inch (psi). The NUHOMS design basis was 3.0 ps The tornado generated missiles analyzed by the NUHOMS FSAR were also bounded by the SONGS UFSAR tornado generated missile For flooding, the SONGS site maximum probable flood was 0.1 feet with a flow rate of 0.34 feet/second (fps). The NUHOMS design criteria was a flood height of 50 feet and a flow rate of 15 fp For seismic criteria, the ISFSI design requirement specified in the NUHOMS FSAR was 1.5 g horizontal and g vertica An NRC inspection of the ISFSI pad conducted on April 22-25, 2002 compared the seismic criteria for the SONGS site to the design basis for the NUHOMS cask syste The results of that inspection were documented in NRC Inspection Report 50-206/2002-07;72-41/2002-01 issued on May 21, 200 The evaluation found that the SONGS site was bounded by the seismic criteria used for the design of the NUHOMS cask Snow and ice considerations were identified in Calculation No. DSC-001 as not being applicable, since the likelihood of snow and ice at the SONGS site was insignificant due to the climate in southern Californi The licensee performed a site specific analysis for a tsunami at the SONGS sit A tsunami was a possibility due to the coastal location of the ISFS The licensee completed Calculation No. C-296-01.02

Section 6.15 of the procedure also provided a caution related to the 80" lifting heigh Step 6.15.11 required that the ambient air temperature of the fuel handling building be measured and recorded prior to lifting the transfer cas The mild climate of Southern California made it highly unlikely that a limitation on the lifting height of the transfer cask while in the fuel handling building will ever be impose The licensee planned the transfer route from Unit 3 to the ISFSI such that the height of the cask would never be over the 80" limit during the movemen With the transfer cask on the transport trailer, the maximum drop height would be 58". When inserting the canister into the advanced horizontal storage module, the maximum height of the canister was approximately 68".
