TSD 14-010 I Revision 6 assumed to be the 5,000 dpm/100 cm2 value in l&E Circular 81-07. Actual detection limits in the unconditional release program are lower than this value. Note that if the use of the 5,000 dpm/100 cm2 maximum non-detect limit is deemed to be too conservative, this dose calculation will be revised based on actual survey detection limits as opposed to the conservative 5,000 dpm/100 cm2 upper value. The vast majority of clean concrete fill to be used will come from two buildings; Containment and Turbine. The source term for the dose assessment is calculated by determining the total surface area of the concrete to be used as backfill, assuming uniform surface contamination at 5,000 dpm/100 cm2 gamma, and dividing the resulting total activity by the volume of concrete fill. The source term is then produced with units of mCi/m3 for both Containment and Turbine. The resulting source terms were 8.57E-04 rnCi/m3 and 4.29E-04 mCi/rn3 for the Turbine Building and Containment, respectively. Consistent with the bounding and conservative approach used for this dose assessment, the maximum source term of 8.57E-04 mCi/rn3 was applied to all concrete fill. Because the source term was from both Containment and Turbine concrete the dose calculation was performed using both the Containment and Auxiliary ROC mixtures. The dose was essentially the same for both mixtures but the dose with the Containment mixture was slightly higher (with trivial exception ofWWTF). Consistent with the bounding approach used for the clean concrete assessment the Containment mixture was applied to all concrete. In addition, when applying the ROC mixture, the 5,000 dpm/100 cm2maximum detection limit was assumed to be 100% Cs-137. The remaining radionuclide concentrations were added to the Cs-13 7 concentration at their respective ratios to Cs-137. The dose values are calculated separately for each basement assuming that the entire basement void is filled with concrete only. This conservatively includes the top three feet of fill which will be soil for all basements and not concrete. The full spreadsheet calculation for clean concrete dose is provided in Attachment 15. The dose results for each basement are provided in Table 33. The dose values in Table 33 will be added to any basement where concrete fill is used regardless of the volume of concrete fill used. This is a conservative and bounding approach.

The demolition plan for the Crib House was revised to leave the interior walls as opposed to removing all interior walls per the original demolition plan. This resulted in a decrease in the Crib House saturated zone fill mass in the Basement Fill Modelwith a corresponding increase in the pCi/g and pCi/L values calculated in TSD 14-009. The BFM and DS dose factors are both directly proportional to the pCi/g and pCi/L concentrations which are inversely proportional to the ratio of the Revised Volume to the Original Volume for the Crib House/Forebay combined. The revised Crib House/Forebay volume and the ratio of the Revised/Original volume is provided in TSD 14-014, Revision 1 (Table 38)Ratio of Revised/Original Crib House/Forebay Volume =8.60E-01
