The RESRAD parameter set is the same as was used for the BFM GW Exposure Factor modeling for ROC described in section 2, including adjustment for the radionuclide independent sensitive parameters in Table 2. The distribution coefficients for the initial suite radionuclides were the lowest values recommended in TSD 14-004 (5) which is the same reference used to select distribution coefficients for ROC BFM RESRAD modeling in section 2.

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 Model with 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 values.The increase in the pCi/g and pCi/L concentrations 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 14-013, Revision 1. Ratio of Revised/Original Crib House/Forebay Volume = 8.60E-01
