TSD 14-010 Revision 4

1. Purpose This Technical Support Document (TSD) provides the input parameters and results of all RESRAD dose assessment modeling required to support the development of the License Termination Plan (LTP) for the Zion Station Restoration Project (ZSRP). RESRAD modeling is required to determine the dose to the average member of the critical group for compliance with 10 CFR 20.1402. This TSD also documents spreadsheet calculations required to convert RESRAD results to Dose Factors and Derived Concentration Guideline Levels (DCGLs) for the Basement Fill Model (BFM).

The Resident Farmer Scenario includes the following exposure pathways (see LTP Chapter 6, section 6.5.4):

Direct exposure to external radiation Inhalation dose from airborne radioactivity Ingestion dose from the following pathways;

- Plants grown with irrigation water from onsite well,

- Meat and Milk from livestock consuming fodder from fields irrigated with onsite well water and consuming water from onsite well,

- Drinking water from onsite well,

- Soil ingestion.

Direct exposure, inhalation dose and ingestion dose from contaminated drilling spoils brought to the surface during installation of the onsite well into the fill material.

The calculation of the dose factors from the drilling spoils pathway, referred to as BFM Drilling Spoils Dose Factors, is provided in ZionSolutions Technical Support Document (TSD)14-021 Basement Fill Model Drilling Spoils and Alternate Exposure Scenarios (1).

The RESRAD parameters and modeling results used to support the calculation of BFM Dose Factors, Basement DCGLs and Soil DCGLs are provided with minimal supporting discussion in this TSD. Full explanation and justification for the BFM and Soil Site Conceptual Models, critical group, exposure scenarios, etc. are provided in LTP Chapter 6. The applicable LTP Chapter 6 sections are referenced in this TSD as necessary.

The detailed RESRAD output reports are provided in this TSD and are used by reference in LTP Chapter 6 summary tables. Separate documentation of the RESRAD output reports in this TSD facilitates independent review and verification of the RESRAD runs. Providing the RESRAD output reports in this TSD, as opposed to the LTP, also allows revision of the RESRAD runs and output reports, if necessary, without full revision, replacement and resubmittal of a large number of LTP attachments. The corresponding summary reports in the LTP would then be revised as necessary.

There are two RESRAD analyses required to support the selection of the Radionuclides of Concern (ROC) for basements and soil in Zion Solutions TSD 14-019, Radionuclides of Concern for Basement Fill Model Source Term and Surrogate Ratios (2). RESRAD dose to source ratios (DSRs) for BFM and soil were required for each of the 26 potential radionuclides in the initial suite to determine which radionuclides were insignificant dose contributors as defined in NUREG-1757, Volume 2, Revision 1, "Consolidated Decommissioning Guidance: Characterization, Survey and Determination of Page 6 of 165

TSD 14-010 Revision 4 Radiological Criteria" (3). The discussion of methods, input parameters an output reports for the BFM and soil RESRAD runs are provided in this TSD. The results of the RESRAD runs were used by reference in TSD 14-019 to determine the relative dose contribution from all radionuclides, identify the ROC for concrete and soil, and calculated the dose fraction attributable to the insignificant contributor radionuclides that were removed from further detailed calculations.

RESRAD runs were also required to calculate Area Factors (AF) for the initial suite of potential radionuclides for use in the calculation of Drilling Spoils Dose Factors in TSD 14-021 which were required to develop the total BFM Dose Factors.

In summary, the following RESRAD runs are required to support the LTP:

1. Basement Fill Model (BFM) sensitivity analysis for ROC,

2. BFM Groundwater Exposure Factors for ROC,

3. Soil Derived Concentration Guideline Level (DCGL) sensitivity analysis for ROC,

4. Soil DCGLs for ROC,

5. BFM modeling to determine Groundwater Exposure Factors for the initial suite of radionuclides in concrete,

6. Soil modeling to determine AFs for the initial suite of radionuclides in concrete to determine BFM Drilling Spoils Dose Factors,

7. Soil modeling for the initial suite of radionuclides in soil,

8. Soil RESRAD modeling for industrial use scenario, and

9. Soil RESRAD Modeling for Kd uncertainty analysis Seven spreadsheet calculations were required to determine the BFM Groundwater and Drilling Spoils Dose Factors, and the final Basement Dose Factors reported in LTP Chapter 6. The methods for calculating the Dose Factors, the documentation of the supporting spreadsheet calculations, and the development of corresponding summary tables reported in LTP Chapter 6 are provided in this TSD.

The required spreadsheet calculations are listed below:

1. Calculation of DUST-MS Groundwater Concentration Factors

2. Calculation of BFM GW Exposure Factors

3. Calculation of BFM GW Dose Factors

4. Calculation of BFM DCGLs

5. Calculation of Basement Surface Drilling Spoils Area Factors

6. Calculation of Clean Concrete Dose

7. Calculation of DCGLs for the Initial Suite Radionuclides

2. Basement Fill Model RESRAD Modeling and Spreadsheet Calculations 2.1. RESRAD Modeling to Determine BFM Groundwater Exposure Factors The RESRADv7.0 computer code was used to calculate the Resident Farmer dose from a unit radionuclide concentration in the well water.

A Groundwater Exposure Factor, in units of mrem/y per pCi/L was generated for each Radionuclide of Concern (ROC). Detailed explanations of the process for determining ROC for the Basements to remain at ZNPS are provided in TSD 14-019 and LTP Chapter 6, section 6.5.2.

The ROC for Zion Nuclear Power Station (ZNPS) Basements are Co-60, Ni-63, Sr-90, Cs-134, Cs-137, H-3, Eu-152 and Eu-154. Note that H-3, Eu-152 and Eu-154 are concrete activation products and apply to the Containment Basements only.

TSD 14-010 Revision 4 The process and justification for the selection of RESRAD parameters to determine BFM Groundwater Exposure Factors are provided in LTP Chapter 6, section 6.6.3. There are two RESRAD analyses required; an uncertainty analysis and a dose analysis that incorporates the parameters deemed sensitive.

2.1.1. BFM RESRAD Uncertainty Analysis The process for determining the input parameters for the BFM RESRAD uncertainty analysis is described in LTP Chapter 6, section 6.6.3.1. The parameter selection process is shown in the flowchart in Figure 1. A number of site-specific parameters were used from two sources; ZionSolutions TSD 14-006, Conestoga Rovers & Associates (CRA) Report, Evaluation of Hydrological Parameters in Support of Dose Modeling for the Zion Restoration Project (4) and ZionSolutions TSD 14-004 Brookhaven National Laboratory (BNL) Report, Recommended Values for the Distribution Coefficient (KD) to be used in Dose Assessments for Decommissioning the Zion Nuclear Station (5).

The RESRAD parameter set used for the uncertainty analysis is provided in Attachment 1.

The uncertainty analysis was conservatively run for all ROC individually to maximize the parameter sensitivity. A more realistic approach would be to use the radionuclide mixture fractions which may reduce the sensitivity of some parameters for the low abundance radionuclides.

The RESRAD Uncertainty Reports and Summary Reports are provided in Attachment 2. Table 1 provides the parameters with lPRCCl values greater than 0.25 and the reported PRCC values. The reported PRCC values are the maximum from the three RESRAD Regression and Correlation outputs provided in the Uncertainty Reports.

Table 2 and Table 3 list the selected 75th or 25th percentile deterministic values from the NUREG/CR-6697 "Development of Probabilistic RESRAD 6.0 and RESRAD-BUILD 3.0 Computer Codes" (6) distributions for the sensitive parameters (i.e., those listed in Table 1).

2.1.2. BFM RESRAD Input Parameters, Output Reports, and BFM Groundwater Exposure Factor Calculation The final RESRAD parameter set used to calculate the BFM Groundwater Exposure Factors is provided in Attachment 3. The parameters in Attachment 3 were developed using the process in Figure 1 and the results of the uncertainty analysis reported in Tables 2 and 3. The RESRAD BFM Summary Report and Concentration Report required for the calculation Groundwater Exposure Factors are provided in Attachment 4.

The Groundwater Exposure Factors are calculated by dividing the maximum dose by the well water concentration at t=0.

Equation 1

()

() =

()

Where:

BFM GW Exposure Factor (i) = Total Resident Farmer dose for radionuclide (i) from unit concentration of groundwater (mrem/yr per pCi/L)

Max Dose (i) = Maximum Resident Farmer Dose for radionuclide (i) from RESRAD Summary Report (mrem/yr)

GW Concentration (i) = Well water concentration for radionuclide (i) from RESRAD Concentration Report (pCi/L)

TSD 14-010 Revision 4 The RESRAD dose and concentration results from Attachment 3 and the results of the Groundwater Exposure Factor calculations are provided in Table 4.

Calculation of Groundwater and Fill Concentration Factors from DUST-MS The initial environmental transport pathway for the BFM Resident Farmer scenario is the release of radioactivity from Basement concrete (or steel liner surfaces for Containment Basements) to water in the interstitial space of the fill material. The water concentrations in the Basements are calculated using the DUST-MS computer code. The methods and results are provided in ZionSolutions TSD 14-009, Brookhaven National Laboratory Report (BNL), Evaluation of Maximum Radionuclide Groundwater Concentrations for Basement Fill Model, Zion Station Restoration Project (7). See LTP Chapter 6, section 6.6.1 for detailed discussion of DUST-MS application in BFM.

The water concentrations and fill concentrations calculated by DUST-MS were used to in conjunction with the assumed radionuclide inventory in each Basement to calculate water and fill concentration factors for each Basement and ROC using Equation 2. The GW Concentration Factors are used in conjunction with RESRAD Groundwater Exposure Factors to calculate BFM Groundwater Dose Factors (see section 2.3). The Fill Concentration Factors are used in the BFM Drilling Spoils Scenario to calculate BFM Drilling Spoils Dose Factors (see section 2.4).

Equation 2

(, )

= (, )/ (, )

where:

GW or Fill Concentration Factor (i,b) = GW or Fill concentration factor for radionuclide (i) and Basement (b) (pCi/L or pCi/g per mCi)

GW or Fill Concentration (i,b) = GW or Fill concentration for radionuclide (i) and Basement (b) (pCi/L or pCi/g)

Inventory (i,b) = assumed inventory for Radionuclide (i) and Basement (b) (mCi)

The GW Concentration Factors and Fill Concentration Factors are calculated in ZionSolutions Excel Spreadsheet Calculations in Support of TSD 14-010 Revision 4.xls. The Excel Worksheet results are provided in Attachment 5. The results are summarized in Tables 5 and 6.

BFM Groundwater Dose Factors BFM Groundwater Dose Factors are dose conversion factors in units of mrem/yr per mCi total inventory. The Resident Farmer dose includes the exposure pathways listed in section 1. The BFM Groundwater Dose Factor accounts for all of the exposure pathways except the drilling spoils pathway which is discussed in section 2.4.

As discussed in detail in LTP Chapter 6, section 6.5.4, operation of a residential well in the Spent Fuel Basement is implausible due to the floor of the Spent Fuel Pool being only three feet below the water table. Therefore, the BFM GW Dose Factors for the Spent Fuel Pool are set to zero. Note that the BFM Drilling Spoils pathway remains active for the Spent Fuel Pool.

The BFM Groundwater Dose Factors are calculated using Equation 3. The spreadsheet calculation inputs and results are provided in ZionSolutions Excel Spreadsheet Calculations in Support of LTP Page 12 of 165

A revision to the demolition plan for the Crib House/Forebay was made that entailed leaving interior walls as opposed to removing them. This resulted in a decrease in the basement mixing volume as compared to that assumed in the DUST-MS modeling provided in TSD-14-009, Revision 0 and a corresponding increase in the fill and groundwater concentrations calculated in TSD 14-009, Revision 0. The BFM GW DFs are directly proportional to the groundwater concentrations which are inversely proportional to the ratio of revised/original mixing volumes. The ratio of the revised/original mixing volumes for the Crib House /Forebay was calculated in TSD 14-014, Revision 1 and determined to be 0.86. The Crib House/Forebay BFM GW Dose Factors were therefore adjusted higher by the inverse of 0.86 or a factor of 1.16. Note that the Crib House/Forebay surface area was also adjusted to account for the additional remaining walls but the change in surface area does not affect the calculation of the BFM Dose Factors because the unit inventory approach used was independent of surface area. The Excel Worksheet results for the correction of the Crib House/Forebay Drilling Spoils Dose Factors is provided in Attachment 6.

TSD 14-010 Revision 4 2.4. BFM Drilling Spoils Dose Factors The BFM Drilling Spoils scenario addresses one of the BFM exposure pathways listed in section 6.5.4 by calculating the dose from residual radioactivity in fill material (resulting from release from surfaces to clean fill after backfill) which is brought to the surface during the installation of a well in the basement. The activity remaining in the concrete surfaces, if any, is also included in the drilling spoils source term. The drilling spoils exposure pathway was included after initial screening in ZionSolutions TSD 14-021 Basement Fill Model (BFM) Drilling Spoils and Alternate Exposure Scenarios (Reference 1) indicated that the pathway could potentially contribute greater than 10% of the total BFM dose. TSD 14-021 also provides the BFM Drilling Spoils Dose Factor calculations.

BFM Drilling Spoils Dose Factors are calculated in units of mrem/yr per mCi total inventory. Table 5 from TSD 14-021 is reproduced in Table 8.

TSD 14-010 Revision 4 2.5. Basement Surface DCGLs Derived Concentration Guideline Levels, in units of pCi/m2 of basement surface area, were calculated for the BFM Groundwater scenario and BFM Drilling Spoils scenario Dose Factors individually and are designated as the DCGLBS (Basement Scenario DCGLs). The Groundwater DCGLBS and Drilling Spoils DCGLBS are combined to generate the Basement DCGL (DCGLB) that accounts for the dose from both scenarios. The DCGLB is directly analogous to the DCGLW as defined in MARSSIM and is the DCGL used during FSS to demonstrate compliance.

A DCGL was calculated for each basement surface survey unit. For the purpose of this calculation, a surface includes all concrete walls and floors of the basements or the steel liner on the walls and floors of Containment. The areal extent of the walls and floors is the surface area and includes all contamination, volumetric at depth and on the surface, within the defined area.

Note that embedded pipe and penetrations will also remain in certain basements. Embedded pipe and penetrations are designated as separate survey units, with separate DCGL calculations, as described in sections 9 and 10, and are not included in the basement surface survey units. However, the total dose in a given basement is determined by summing the dose from all survey units within the basement including surface, embedded pipe, and penetrations. The dose from each survey unit is calculated using the mean FSS results (plus the results of judgmental samples and elevated areas if applicable) after the survey unit passes the Sign Test (see LTP Chapter 5).

After the basement surface areas were adjusted (as described in section 2.5.1), the DCGLBS values were calculated for each basement surface survey unit using Equation 4.

TSD 14-010 Revision 4 2.5.1. Basement Surface Area Adjustments Basement surface area adjustments were required to ensure that the DCGLs account for the contribution of residual radioactivity from basements/structures that cannot, on their own, support a water supply well but are hydraulically connected to a basement that can support a well. The first area adjustment is to the Turbine Basement and Crib House/Forebay. The activity in the Circulating Water Intake Pipes is included in both the Crib House/Forebay and the Turbine Basement. The activity in the Circulating Water Discharge Tunnels is included with the Turbine Basement.

The DCGL calculations account for the activity in the Intake Pipe by summing the surface areas of the Intake Pipe and Crib House/Forebay. The activity in the Discharge Tunnel is accounted for by summing the surface areas of the Discharge Tunnel and Turbine Basement. The surface area of the Intake Pipe is also added to Turbine basement because openings were cut into the Intake Pipe at a point within the Turbine Basement to access the pipe for FSS measurements. There are also several large pipes ranging in diameter from 36 inches to 12 feet that connect the Turbine basement to the Circulating Water Discharge Tunnels and have been cut and sealed by water tight weld of a 1 inch thick steel plate over the opening. These pipes are designated as Circulating Water Discharge Pipe and the area in these pipes is also included in the area summation for the Turbine Basement DCGL calculation. The Buttress Pits and Tendon Tunnels are hydraulically connected to the Turbine Basement (via the Steam Tunnels). The surface areas of these structures are therefore also added to the Turbine Basement.

The summed areas were then used as the SAb (adjusted) term in Equation 4 to calculate the DCGLs for the Crib House/Forebay and Turbine Basement. As seen in Equation 4, increasing the surface area decreases the DCGLs. The lower DCGLs calculated for the Crib House/Forebay and Turbine Basement, based on the summed areas, were then also applied to the Circulating Water Intake Pipes, Discharge Tunnels (and associated Circulating Water Pipes), and Buttress Pits and Tendon Tunnels.

These areas are accounted for during FSS by summing with the associated basements as listed in Table

11. See LTP Rev 1, Chapter 5, section 5.5.7.1 for details on how the summation will be performed during FSS data assessment.

A second surface area adjustment was required in the DCGL calculations to account for the contribution of residual radioactivity in the SFP/Transfer Canal to the groundwater pathway. As discussed in LTP Chapter 6, section 6.5.4, the SFP/Transfer Canal geometry could not support a water well and therefore the BFM Groundwater Dose Factor was set to zero (see Table 7). However, the potential for the residual radioactivity in the SFP/Transfer Canal to contribute to the groundwater is accounted for by adding the SFP/Transfer Canal source term (as represented by the surface area) to the Containment Basement and to the Auxiliary Basement. The activity could mix with the Containment Basement through the Fuel Transfer Tube. Activity could mix with the Auxiliary Basement through an opening created by removing the wall between the Transfer Canal and Auxiliary Basement during demolition. The surface area adjustment, and corresponding DCGL calculations, conservatively assume that the activity in the SFP/Transfer Canal is in both the Containment and Auxiliary Basement simultaneously.

The inputs to the calculation of the adjusted surface area for each basement surface area adjustments are provided in Table 9 and Table 10. Table 11 provides the adjusted surface areas for the DCGL calculation. Basements not listed in Table 11 (SFP/Transfer Canal and WWTF) did not require adjustment and the areas in Table 9 are used for the DCGL calculation.

In accordance with NUREG 1757, the insignificant radionuclides can be removed from detailed assessment but the dose attributable to the removed radionuclides must be accounted for. As discussed in LTP Chapter 6, section 6.5.2.3, the insignificant contributor dose percentage was assigned a value of 10% for Containment and 5% for all other basements. The insignificant contributor dose adjustment factor is therefore 0.90 (1-0.10) for Containment and 0.95 (1 - 0.05) for all other basements. The Adjusted DCGLs are calculated using Equation 6-5 with the results provided in Tables 15, 16, and 17. Note that the DCGL for Spent Fuel Building/Transfer Canal set equal to the lower of either the Auxiliary or Containment DCGL. Because the Containment DCGL was lower for all ROC the Spent Fuel Building/Transfer Canal DCGL were set equal to Containment DCGL.

BFM Drilling Spoils Scenario Area Factor An area factor (AF) for the BFM Drilling Spoils Scenario was calculated for the Elevated Measurement Comparison test. The Drilling Spoils AF applies to floors only. An AF is required for all Class 1 survey units which include only the Auxiliary Basement and SFP/Transfer Canal.

The AF is based on the assumption that all of the activity is on the floor as opposed to the being distributed over the walls and floors as in the DCGLBS calculation. If all of the allowable activity is distributed over the floor only, the activity in the drilling spoils after contacting the floor will result in 25 mrem/yr as required by the AF definition. Basing the Drilling Spoils AF on this assumption is conservative in that it assumes that all of the measured activity either remains in the concrete after license termination or is released to a hypothetical 8 inch diameter column of fill directly above the elevated area with no horizontal mixing.

The first step in the AF calculation is to modify the DCGLBS in Table 16 by the ratio of total surface area (walls and floors) to the floor surface area only. This results in concentration (pCi/m2) on the floor that would result in 25 mrem/yr for the drilling spoils pathway only. The Drilling Spoils AF is then calculated by dividing the modified Drilling Spoils DCGLBS by the DCGLB. The AF calculation is shown in Equation 6. The basement floor areas and the resulting AFs are provided in Tables 18 and 19 (the total surface areas are provided in Table 11). The calculations are performed in Excel spreadsheet TSD 14-010 Revision 4.xls. The worksheet inputs and results are reproduced in 7.

TSD 14-010 Revision 4

3. RESRAD Modeling for Soil DCGL Determination Site-specific DCGLs were developed for residual radioactivity in surface and subsurface soil that represent the 10 CFR 20.1402 dose criterion of 25 mrem/yr. A DCGL was calculated for each ROC determined in TSD 14-019. The ROC are Cs-137, Cs-134, Co-60, Cr-90, and Ni-63.

Surface soil is defined as contamination contained in the first 0.15 m layer of soil. Subsurface soil is defined as a layer of soil beginning at the surface that extends beyond 0.15 m. The Subsurface soil thickness is arbitrarily set to a 1 m depth. DCGLs are calculated for both the 0.15 m and 1 m thicknesses. Both the surface and subsurface DCGLs assume a continuous source term layer from the ground surface downward. There are no expectations of encountering soil contamination in a geometry consisting of a clean surface layer of soil over a contaminated subsurface soil layer.

Detailed description of the soil DCGL conceptual model and parameter justification is provided in LTP Chapter 6, section 6.8.

RESRAD version 7.0 was used to calculate DCGLs for surface and subsurface soil.

3.1. Soil Uncertainty Analysis Parameter uncertainty analysis was performed following the process described in LTP Chapter 6, section 6.9.2. The parameters used for the uncertainty analysis of the surface and subsurface soil dose modeling are the same as were used for the BFM RESRAD uncertainty analysis, with the exception of contaminated zone thickness. A 0.15 m thickness is used for surface soil and 1.0 m thickness for subsurface soil. The unsaturated zone depth was also adjusted to ensure that the depth to the water table remains constant for both the 0.15 m and 1.0 m contaminated zone thicknesses.

The RESRAD input parameters used for the uncertainty analysis of both surface and subsurface soil are provided in Attachment 7. The RESRAD Uncertainty Reports were generated for surface and subsurface soil and for each ROC individually. The reports are provided in Attachment 8.

Deterministic parameters were selected for behavioral, metabolic and Priority 3 physical parameters in accordance with the process in Figure 1. The majority of the Priority 1 and 2 physical parameters are assigned the parameter distributions from NUREG/CR-6697.

Surface soil parameters with a lPRCCl result greater than 0.25 are listed in Table 20. Tables 21 and 22 provide the selected 75th or 25th percentile deterministic values for surface soil from the NUREG/CR-6697 distributions for the positively and negatively correlated parameters, respectively.

Subsurface soil parameters with a lPRCCl result greater than 0.25 are listed in Table 23. Tables 24 and 25 provide the selected 75th or 25th percentile deterministic values for subsurface soil. The median of the NUREG/CR-6697 distributions was assigned to the Priority 1 and 2 parameters that were not sensitive (i.e., not listed in Tables 6-20 and 6-23).

RESRAD Results and Soil DCGLs The surface and subsurface soil DCGLs were calculated using the deterministic parameter set provided in Attachment 9. The RESRAD Summary Reports for surface and subsurface soil are provided in 0.

The surface and subsurface soil DCGLs are provided in Table 26. The insignificant contributor dose percentage calculated in TSD 14-019 is 0.171%. However, to provide additional margin and allow for Page 25 of 165

TSD 14-010 Revision 4 simplified assessment of additional HTD analysis of soil during continuing characterization, the applied insignificant dose contribution was increased to 10%. The adjustment factor is 0.90 (1-0.1).

The adjusted DCGL are calculated by multiplying the values in Table 26 by 0.9 and are provided in Table 27.

4. RESRAD Modeling for Concrete Radionuclide of Concern Selection 4.1. BFM GW Dose Factors and DCGLs for the Initial Suite of Potential Radionuclides The set of radionuclides evaluated in section 2 was comprised of the ROC selected in TSD 14-019.

The process of selecting the ROC entailed determining an initial suite of radionuclides that could potentially be present at ZNPS and then removing insignificant dose contributors from the initial suite.

A systematic screening process was used to remove very low abundance or low probability radionuclides from a comprehensive list of all possible radionuclides resulting in the initial suite that is reproduced in Table28. See LTP Chapter 6, Section 6.5.2 and TSD 14-019 for detailed discussions of the process for selecting the initial suite.

TSD 14-010 Revision 4 NUREG-1757, section 3.3 states that radionuclides contributing no greater than 10% percent of the dose criterion (i.e., 2.5 mrem/yr) are considered to be insignificant contributors. This 10% percent criterion applies to the sum of the dose contribution from the aggregate of radionuclides designated as insignificant contributors.

TSD 14-019 uses the results of BFM RESRAD dose modeling for the initial suite in conjunction with DUST-MS modeling by TSD 14-031, "Brookhaven National Laboratory Report: Basement Fill Model Evaluation of Maximum Radionuclide Concentrations for Initial Suite of Radionuclides" (8) to determine the BFM Dose Factors from the initial suite radionuclides in the same manner as described in section 2 for the ROC radionuclides. The BFM Dose Factors calculated in TSD 14-019 are used with the radionuclide mixture fractions in ZNPS concrete to calculate relative dose. An initial estimate of the relative dose contribution from insignificant contributors was calculated and the ROC nuclides selected.

The RESRAD parameters used for the BFM modeling of the initial suite radionuclides are provided in 1. The RESRAD Summary Report and Concentration Report are provided in Attachment 12.

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.

A detailed uncertainty analysis, including all 26 radionuclides, was not merited for the ROC screening calculations given the apriori understanding that only limited water dependent pathways are applicable to the BFM. ROC screening is based on relative dose between the 26 radionuclides in Table 17, not absolute dose, so the significance of parameter variability is reduced. Notwithstanding the relative nature of the ROC screening assessment, qualitative uncertainty analysis was performed which indicated that approximately 50% of the dose for Cs-137 (the predominate radionuclide) was attributable to the plant, meat and milk ingestion pathways with the remainder of the dose from drinking water. For simplicity and to ensure that the calculated dose is conservative for all radionuclides, the plant/meat/milk transfer factors were set to the 75th percentile of the NUREG-6697 distribution for all radionuclides. This was done to maximize the relative dose, particularly for the low abundance radionuclides, to ensure that the dose attributed to the insignificant contributors is maximized. Note that for the eight ROC, the plant transfer factors were set to the same values used in Table 3 based on sensitivity analysis. This ensures that the values for the ROC in both RESRAD runs are the same and further maximizes the impact of the low abundance radionuclides.

The final calculation of dose from insignificant contributor radionuclides was performed in TSD 14-019 using BFM DCGLs that were calculated for the initial suite radionuclides. Insignificant contributor dose calculations were also performed for the Drilling Spoils DCGL alone because the Drilling Spoils were used separately to calculate BFM AFs (see section 2.6).

The initial suite DCGLs were calculated using the same process described for ROC DCGLs in section 2.5. The calculations were performed in Excel spreadsheet TSD 14-010 Revision 4.xls. The inputs and calculation results are provided in Attachment 18.

TSD 14-010 Revision 4 4.2. Soil Area Factors for Determining BFM Drilling Spoils Dose Factors for the Initial Suite of Potential Radionuclides As described in TSD 14-021, soil AFs were required for the initial suite of radionuclides for four area sizes as listed below:

0.1 m2 0.3 m2 3.0 m2 10 m2 RESRAD runs were required for the above areas as well as the base case area of 64,500 m2 to determine the AFs for the initial suite of radionuclides. The AFs are calculated in TSD 14-021 using the RESRAD results. The soil RESRAD input parameters for the AF runs were the same as those used for soil DCGLs (see Attachment 9) with the parameters for contaminated fraction of plant food, meat and milk changed from 1 to -1 to allow RESRAD to account for smaller contaminated areas. The length parallel to aquifer flow also required adjustment to be consistent with the smaller areas. The methods used for RESRAD modeling for AFs is the same as described in Zion Solutions TSD 14-011, Soil Area Factors (9). The RESRAD Summary Reports are provided in Attachment 13.

5. RESRAD Modeling for Soil Radionuclide of Concern Selection As described in TSD 14-019, the initial suite radionuclides in Table 17 were also used to determine the ROCs, and insignificant contributors for soil. A RESRAD run was required to determine the dose to source ratio for all initial suite radionuclides in order to identify the insignificant dose contributors and the dose from the aggregate of insignificant contributor radionuclides removed from detailed consideration.

The RESRAD parameter set was the same as used for the ROC DCGL calculation with two adjustments. First, soil distribution coefficients were required for all additional radionuclides in the initial suite which were selected from the same source that was used for the ROC RESRAD analysis, i.e., Reference 7. Daughter products were assigned the mean of the NUREG 6697 distribution as was done for the BFM initial suite evaluation for ROC determination. An additional change was setting all plant, meat, and milk transfer factors to the 75th percentile to maximize the dose contribution from all radionuclides. Note that for the 5 ROCs, the plant transfer factors were the same as were used in Table 11 based on sensitivity analysis. This ensures that the values for the ROCs in both RESRAD runs are the same and maximizes the impact of the low abundance radionuclides. The surface soil source thickness (0.15 m) was used in the initial suite runs for ROC determination because minimal, if any, soil contamination is expected below 0.15 m based on characterization results.

The RESRAD Summary Report for the RESRAD analysis of the initial suite radionuclides for soil ROC determination is provided in Attachment 14.

6. RESRAD Soil Dose Modeling for Industrial Use Alternate Scenario An Alternate dose scenario is evaluated in TSD-021 that assumes large scale industrial excavation of the ZION basements after license termination. Excavation of the very deep basements would be prohibitively expensive and is considered a less likely but plausible scenario. NUREG-1757, Table 5.1, states that assessment of a less likely but plausible scenario is not analyzed for compliance, but is used to risk-inform the decision.

Page 28 of 165

TSD 14-010 Revision 4 If a large scale excavation of the basements, were to occur it would not be for residential use but to develop the property for industrial use. The cost and technical challenges of the excavation required for the deep basements, that are all below the water table, would only be justified for a large scale industrial project that would be present on the site for decades. Therefore, for the assessment of the large scale industrial excavation scenario a dose assessment is required that assumes industrial use as opposed to residential use. This section describes the RESRAD input parameters used for modeling an industrial use scenario for soil and provides the results of the dose assessment. The resulting DCGLs are used in TSD 14-021 to assess the large scale industrial excavation alternate scenario.

The large scale excavation scenario in TSD 14-021 assumes that the excavated material is spread on the surface over a 1 m depth. Therefore, the RESRAD parameters for the industrial use soil assessment were set to the same values as used for the Subsurface soil dose assessment (see Attachment 9) with the following changes:

Inhalation Rate: 1917 m3/yr NUREG/CR-5512, Vol. 3 Table 5.1.1 mean value is 8400/y which equates to 23 m3/d.

Majority of industrial work is expected to be indoors. Consistent with Table 2-3 of the Users Manual for RESRAD Version 6, 75% of work time is indoors and 25% outdoors. The corresponding RESRAD indoor Fraction parameter = (2190*0.75)/(24*365) = 0.1875 Fraction of time spent outdoors (onsite): 0.0625 As explained in the basis for the Indoor Fraction parameter, the indoor time fraction was set at 75% and outdoor time fraction at 25%. The corresponding RESRAD outdoor time fraction is (2190*.25)/(24*365) = 0.0625.

Kds for remaining radionuclides are set to minimum values in the Subsurface Soil parameter set used therefore no adjustment required.

TSD 14-010 Revision 4 The resulting Industrial Use DCGLs are listed in Table 29 column 2. Note that H-3, Eu-152, and Eu-154 were added to the list of radionuclides evaluated because the industrial use scenario DCGLs were used in TSD 14-021 to evaluate the excavation of backfilled concrete which includes and H-3, Eu-152 and Eu-154 as ROCs for the Containment Basement. Table 29, column 3 provides the DCGLs after adjustment to account for the dose fraction attributable for the removed insignificant contributors. The calculated insignificant dose fraction assigned to surface soil, i.e., 0.171% (see TSD 14-019 Revision 2 Table 24), was used to adjust the industrial use DCGLs. This is conservative because the plant pathways are not applicable to industrial use which reduces the relative dose fraction from non-gamma emitting radionuclides (i.e., HTD radionuclides) which are the vast majority of radionuclides removed as insignificant dose contributors.

7. Soil Kd Uncertainty and Sensitivity Assessment An assessment was performed to determine the sensitivity of soil dose to Kd. Four soil types were sampled from the Zion site and analyzed by Brookhaven National Laboratory for Kd; Disturbed Sand, Native Sand, Silt/Clay, and Clay (Reference 5). The site surface and subsurface soil is contained in the Upper Sand Unit and is a mix of Disturbed Sand and Native Sand. The majority of the site surface soil is Disturbed Sand. The Silt/Clay and Clay were sampled from depths of 24-28 below ground surface (bgs) and 31-36 bgs, respectively. These samples were collected to understand the characteristics of the Upper Silt/Clay Unit which underlies the Upper Sand Unit. The Upper Silt/Clay unit is an aquitard that inhibits groundwater flow between the Upper and Lower Sand Unit aquifers. The Zion dose model conservatively assumes that all wells are screened in the Upper Sand Unit as opposed to the Lower Sand Unit which is isolated from the Zion site source term by the clay aquitard.

The site soil type (down at least several feet) is predominantly Disturbed Sand as a result of excavation and backfill during plant construction. However, some areas could consist of Native Sand Kds.

Therefore, both sand types are considered applicable to the surface (0.15 m depth) and subsurface (1 m depth) soil categories. The site-specific Kds for Native Sand and Disturbed Sand are listed in Reference 5 for each ROC and shown in Tables 30 and 31.

Page 30 of 165

TSD 14-010 Revision 4 The assessment included a probabilistic uncertainty analysis for Surface and Subsurface soil with the Kds being the only parameters considered probabilistically. This maximizes the effect of Kd on the dose results and the chance for a Kd being identified as sensitive (using the criteria described in section 3.1, i.e., absolute value of PRCC being greater than 0.25). The Kd parameter distributions were entered in RESRAD as uniform distributions with minimum and maximum values defined by the Native or Disturbed sand site-specific Kds. The uncertainty analysis did not identify any of the Kd parameters as being sensitive. The RESRAD Uncertainty Report file names are listed below. The reports are stored electronically.

Zion Subsurface Soil Sensitivity RESRAD Uncertainty Report.pdf Zion Surface Soil Sensitivity RESRAD Uncertainty Report.pdf An additional sensitivity analysis was performed that included deterministic RESRAD analyses of Surface Soil and Subsurface Soil using the maximum site-specific sand Kd. The resulting DCGLs were compared to the DCGLs calculated using the minimum site-specific sand Kd. The file names of the two RESRAD Summary Reports used for the analysis are listed below. The full reports are stored electronically.

Zion Subsurface Soil Sensitivity RESRAD Summary Report.pdf Zion Surface Soil Sensitivity RESRAD Summary Report.pdf The results are summarized in Tables 30-32. The deterministic approach is very conservative in that it includes each radionuclide independently and ignores the actual dose consequences of a given radionuclide in the context of the radionuclide mixture. As seen on Table 32, when Sr-90 is considered independently the maximum Kd resulted in a DCGL that was 6% lower. Ni-63 is lower by a very small fraction. The gamma emitters, which represent the vast majority of dose form soil were not affected by the Kd change.

Although the Sr-90 DCGL was lower by 6% with the maximum Kd, when the radionuclide mixture percentage of Sr-90 is considered the dose consequences are orders of magnitude lower than 6%.

Notwithstanding the fact that the calculated dose increase if very low, the maximum Kds will be used for both Sr-90 and Ni-63 in the Surface and Subsurface DCGL modeling.

8. Clean Concrete Fill ZSRP will demonstrate that all concrete designated as backfill material in basements is clean by using the Unconditional Release Survey (URS) program at Zion presented in ZionSolutions procedure ZS-LT-400-001-001, Unconditional Release of Materials, Equipment and Secondary Structures. The URS ensures that no detectable plant-derived radioactive material is released from the site.

MARSAME guidance is used in establishing survey intensities, and NRC has reviewed and audited the ZSRP unconditional release programs and found them to be acceptable. Materials unconditionally released from Zion, regardless of their point of origin on the site, have been verified to contain no detectable plant-derived radioactivity and are free to be used and relocated anywhere offsite without tracking, controls, or dose considerations.

The URS is performed in accordance with procedure ZS-LT-400-001-001 which requires ambient background to be determined for the area of the survey and a critical level based on the ambient background be derived for the instrument used. If a measurement result is greater than the critical level established for the instrument in the area specific to the material being surveyed, then an investigation is performed, typically using a portable gamma spectroscopy instrument (Inspector) but in some cases a volumetric sample is taken. If the investigation positively identifies plant-derived radioactivity, then the material may not be unconditionally released. In the case of concrete surveyed as candidate material for use as clean fill, the material would be disqualified for use as fill, segregated and disposed of as low level radioactive waste.

Although the concrete to be used as fill is clean and can be viewed as having a zero dose impact, a dose value will be assigned for the purpose of demonstrating compliance with 10 CFR 20.1402 in the same manner as other materials to remain at license termination that are surveyed and found to not contain detectable activity. The detection limit used for the dose calculation is conservatively Page 32 of 165

TSD 14-010 Revision 4 assumed to be the 5,000 dpm/100 cm2 value in I&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 mCi/m3 and 4.29E-04 mCi/m3 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/m3 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 of WWTF). 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 cm2 maximum detection limit was assumed to be 100% Cs-137. The remaining radionuclide concentrations were added to the Cs-137 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.

9. DCGLs for Embedded Pipe DCGLs are required for each survey unit that undergoes FSS. As defined in MARSSIM, the DCGL, based on pathway modeling, is the uniform residual radioactivity concentration level within a survey unit that corresponds to the release criterion. The total internal surface areas of all Auxiliary Building Basement floor drains were combined to comprise a single survey unit. DCGLs were calculated for each radionuclide of concern (ROC) in units of pCi/m2.

Embedded piping is defined as piping that runs vertically in a concrete wall or horizontally in a concrete floor. The residual radioactivity in embedded piping to remain has no release pathway other than into the Basement(s) where the piping terminates. Each embedded pipe run is treated as a separate survey unit within the basement that the embedded pipe is located and the DCGL calculated accordingly.

The embedded pipe to remain in the End State is identified and quantified in ZionSolutions TSD 14-016, Description of Embedded Piping, Penetrations and Buried Piping to Remain in Zion End State (10). The embedded pipe survey units are listed in Table 34 along with the total internal survey area of the pipes in the survey unit. The IC-sump embedded pipe is very limited with a total surface area of 1.05 m2 each for unit 1 and unit 2. To provide a reasonable maximum value for the DCGL a nominal area of 100 m2 was assumed for the surface area of IC sump embedded pipe survey unit.

Note that the Tendon Tunnel Floor drains are included in both the Containment and Turbine Basement compliance demonstration (see LTP Rev 1, Chapter 5, Table 5-15). The embedded pipe DCGL was calculated for both basements (see Attachment 19). The DCGLs calculated using the Containment Basement Dose Factors in Equation 7 were lower than using the Turbine Basement Dose Factors and were therefore assigned as the Tendon Tunnel floor drain DCGLs. The DCGLEP values are provided in Table 35.

10. Penetration DCGLs A penetration is defined as a pipe (or remaining pipe sleeve, if the pipe is removed, or concrete, if the pipe and pipe sleeve is removed) that runs through a concrete wall and/or floor, between two buildings, and is open at the wall or floor surface of each building. A penetration could also be a pipe that runs through a concrete wall and/or floor and opens to a building on one end and the outside ground on the other end.

A penetration survey unit is defined for each basement. The direction that the residual radioactivity may migrate, i.e., into which basement, cannot be predicted with certainty. Therefore, a given penetration that begins in one basement and ends in another will be included in the survey units for both basements. The residual radioactivity in the penetration is assumed to release to both basements simultaneously.

The penetration DCGL (DCGLPN) is calculated in the same manner as embedded pipe using Equation 7 but replacing the embedded pipe survey unit surface area with the penetration survey unit surface area. The penetration survey units are defined in TSD 14-016 with each pipe in the survey unit listed.

TSD 14-016 also calculates the total survey area of each penetration survey unit which are provided in Table 36.

Auxiliary Basement 948.75 Containment Basement 242.36 Turbine Basement 1081.14 SFP/Transfer Canal 337.45 Crib House/Forebay 1.14 WWTF 0.89 An additional adjustment is required for the calculation of the DCGLPN for the Auxiliary Basement penetration survey unit. The release of residual radioactivity from the Auxiliary basement concrete assumes diffusion release. In most cases the remaining penetrations will be either the remaining pipe or steel pipe sleeve after a pipe is removed. Because the residual radioactivity is not contained at depth in concrete, the assumption of diffusion release through concrete is not applicable and instant release is conservatively assumed for the penetrations. As seen in Equation 7, the penetration DCGL calculation uses the BFM Dose Factors, which in the case of the Auxiliary basement is based on assumption of diffusion release. An adjustment is therefore required to account for the higher maximum release rate under an instant release assumption as compared to diffusion release. The correction factor was calculated in TSD 14-009, Revision 3, Attachment G, where the maximum concentration in the Auxiliary Basement under an instant release assumption was compared to the maximum concentration using a diffusion release assumption. The adjustment factor was calculated as the ratio of maximum instant release to maximum diffusion release. The results from TSD 14-009, Revision 3, Attachment G are reproduced in Table 37.

These penetrations are included with the Crib House/Forebay and WWTF surface survey unit and the surface DCGLB will apply.

11. Action Levels for Remediation and Grouting of Penetrations Administrative action levels are set in LTP Chapter 5 for the decision to remediate and/or grout a penetration or embedded pipe. The remediation and grouting action levels ensure that the residual radioactivity in the penetration of embedded pipe will either not exceed the wall/floor surface DCGL or that the activity released from the embedded pipe to the floor surface, after grouting, will be well below that which could be released from a wall/floor surface at the DCGL concentration The lower action levels for embedded pipe is the wall/floor surface DCGLB (or SOF including all ROC) for the basement that contains the embedded pipe. The upper action level is the embedded pipe DCGL (SOF).

The lower action levels for penetrations are the most limiting DCGLB (SOF) of the two basements where a penetration interfaces. The upper action level is the penetration DCGL (SOF). The lower action levels for penetrations are calculated in this section.

As described in section 11, the penetrations DCGLs are adjusted to account for the different maximum concentration under instant and diffusion release assumptions. However, the calculation in section 11 applies to the DCGLPN for the Auxiliary penetration survey unit. To ensure that the lower action levels associated with the remediation and grouting of the Auxiliary Basement penetration survey unit satisfy the objective of either not exceeding the Auxiliary wall/floor surface DCGL, the lower action lower for the Auxiliary penetration must also be adjusted to account for the differences between instant and diffusion release. The most straightforward way to calculate the lower action level for the Auxiliary penetrations is to divide the Auxiliary wall/floor surface DCGLB values in Table 14 by the ratios in Table 37. This ensures that the release from 1 m2 of penetration surface area will be equivalent to the release from 1 m2 of a floor/wall surface at the DCGLB. The Auxiliary penetration lower action levels Page 38 of 165

TSD 14-010 Revision 4 are calculated in Excel spreadsheet file: TSD 14-010 Revision 4.xls. The spreadsheet inputs and calculation results are provided in Attachment 20. The results are provided in Table 39.

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 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)
