TSD 14-010 Revision 2

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 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 a nd M ilk f rom liv estock c onsuming fodder f rom f ields ir rigated w ith o nsite w ell 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 and to calculate 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 Radiological Criteria" (3). The discussion of methods, input parameters an output reports for the BFM Page 5 of 123

TSD 14-010 Revision 2 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 Four 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 Basement Dose Factors

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.

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.

Page 6 of 123

TSD 14-010 Revision 2 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)

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 2.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 11 of 123

TSD 14-010 Revision 2 Chapter 6, Rev 2.xls. The Excel Worksheet results are provided in Attachment 6. The results are summarized in Table 7.

Equation 3

(, ) = (, ) x ()

where:

BFM GW Dose Factor (i,b) = BFM Groundwater Dose Factor for radionuclide (i) and Basement (b) (mrem/y per mCi)

GW Concentration Factor (i,b) = Groundwater Concentration Factor for Radionuclide (i) and Basement (b) (pCi/L per mCi)

GW Exposure Factor (i) = Groundwater Exposure Factor for radionuclide (i) (mrem/y per pCi/L.

Basement Dose Factors Compliance with the 25 mrem/yr dose criterion will be demonstrated after the remaining residual radioactivity inventory has been determined by the final radiation survey. The total inventory remaining for each ROC, in each Basement, will be multiplied by the applicable Basement Dose Factor. The dose contribution for each ROC in a given Basement will be accounted for using the sum of fractions rule.

The Basement Dose Factors are calculated as the sum of the BFM GW Dose Factors and BFM Drilling Spoils Dose Factors (calculated in TSD 14-021) which together account for the dose from all of the Resident Farmer exposure pathways listed in section 1. As discussed in section 6.5.4, only the BFM Drilling Spoils Dose Factors are applicable to the Spent Fuel Pool, i.e., the BFM GW Dose Factors are assumed to be zero.

TSD 14-010 Revision 2 An additional step in the calculation of the Basement Dose Factors is adjustment for the dose contribution from insignificant dose contributors. 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. From TSD 14-019, Table 19, the insignificant contributor dose contribution for the Containment and Auxiliary Basements was 0.514% and 1.32%, respectively.

Although the calculated insignificant contributor dose fractions are conservative due to the application of minimum detectable concentrations (MDC) values in the calculation for the majority of HTD radionuclides, the dose fractions were multiplied by a factor of 2 (100% increase) to provide additional margin to account for potential uncertainty in the radionuclide mixture. The Auxiliary Basement percentage was applied to all Basements except Containment noting that the insignificant contributor dose will be reviewed and revised, if necessary, based on results of continued characterization.

The Basement Dose Factors are calculated using Equation 4. The insignificant contributor dose adjustment factors in Equation 4 are 1.010 (1/(1-2*0.00514) and 1.027 (1/(1-2*0.0132) for the Containment Basement and all other Basements, respectively.

Two additional basement-specific adjustments were made. First, there was a revision to the demolition plan for the Crib House/Forebay 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 Basement Dose Factors are directly proportional to the fill and 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 14-013, Revision 1 and determined to be 0.86. The Crib House/Forebay BDFs were therefore adjusted higher by the inverse of 0.86 or a factor of 1.16.

Second, the Basement Dose Factors for the SFP/Transfer Canal were adjusted to equal the higher of either the Containment or SFP/Transfer Canal values. This adjustment was driven by the commitment in LTP Chapter 6 section 6.5.4 to account for the potential groundwater dose from residual radioactivity in the SFP/Transfer Canal by adding the SFP/Transfer Canal inventory to the Containment inventory in order to ensure that the sum of the two inventories does not exceed the Containment inventory limit. Therefore, in practice, the SFP/Transfer Canal BILs cannot exceed the Containment BILs. Maximizing the Basement Dose Factors minimizes the inventory limit.

The final Basement Dose Factors for each Basement and ROC are listed in Table 8.

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.

TSD 14-010 Revision 2 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 9. Tables 10 and 11 provide the selected 75 th or 25 th 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 12. Tables 13 and 14 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 6-9 and 6-12).

TSD 14-010 Revision 2 3.2. 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 15. The insignificant contributor dose percentage calculated in TSD 14-019 is 0.171%. However, to provide additional margin and allow for simplified assessment of additional HTD analysis, if any, 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 15 by 0.9.

4. RESRAD Modeling for Concrete Radionuclide of Concern Selection 4.1. BFM GW Dose Factors 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 Table 17. See LTP Chapter 6, Section 6.5.2 and TSD 14-019 for detailed discussions of the process for selecting the initial suite.

Page 17 of 123

TSD 14-010 Revision 2 Table 17 List of 26 potentially significant radionuclides (from TSD 14-019)

H-3 Co-60 Tc-99 Cs-137 Eu-155 Pu-241 C-14 Ni-63 Ag-108m Pm-147 Np-237 Am-241 Fe-55 Sr-90 Sb-125 Eu-152 Pu-238 Am-243 Ni-59 Nb-94 Cs-134 Eu-154 Pu-239/240 Cm-243/244 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. 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.

Page 18 of 123

TSD 14-010 Revision 2 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 19 of 123

TSD 14-010 Revision 2 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.

Industrial Scenario m3/yr =23 m3/d ÷ 24h/d

2000 h/y.

Fraction of time spent indoors: 0.1875 NUREG-6697 Att. C, Table 7.6-1 recommends a median indoor work day as 8.76 hour8.796296e-4 days 0.0211 hours 1.256614e-4 weeks 2.8918e-5 months s/day.

Assuming 5 days a week and 50 weeks per years this equates to 2190 hours0.0253 days 0.608 hours 0.00362 weeks 8.33295e-4 months per year. 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.

Drinking water intake: 327 L/y NUREG/CR-5512, Vol. 3 Table 6.87. Industrial Scenario water supply assumed to be from an onsite well. 478 L/y from NUREG/CR-5512 corresponds to 1.31 L/d which is considered a conservative value for 8 hour9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months work day. 1.31 L/d

Kds for Sr-90 and Ni-63 set to the minimum site-specific values to maximize dose through groundwater pathway which is predominant pathway with plant/meat/milk inactive. Kds for remaining radionuclides are set to minimum values in the Subsurface Soil parameter set used therefore no adjustment required.

Zion Industrial Use Soil RESRAD Summary Report 5_27.pdf Page 20 of 123

TSD 14-010 Revision 2 The resulting Industrial Use DCGLs are listed in Table 7 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 17, 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 Page 21 of 123

TSD 14-010 Revision 2 (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 18 and 19.

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 18-20. 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 20, 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 Page 23 of 123

TSD 14-010 Revision 2 contain detectable activity. The detection limit used for the dose calculation is conservatively 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 22. The dose values in Table 22 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.

TSD 14-010 Revision 2 Note 1: Spent Fuel Pool/Transfer Canal Dose Factors set at the highest of either Containment or SFP/Transfer Canal Note 2: The Crib House/Forebay Dose Factor was adjusted higher to account for a revision that lowered the void volume.

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 14-013, Revision 1.

Ratio of Revised/Original Crib House/Forebay Volume = 8.60E-01 Page 65 of 123
