-May 1989, EPA/600/P-95/002F August 1997.4. METHOD OF CALCULATION The operability of the RESRAD Version 6.4 code was verified on each computer used for code executions in accordance with Bartlett Engineering procedure ENG-AP-02, Verification of Software Operability (ref. 3.13). The RESRAD User's manual (ref. 3.3) provided guidance for code operation and execution. | |||
The RESRAD code has undergone extensive review, benchmarking, verification, and validation. | Bartlett Engineering Calculation ENG-004 Calculation of DTE EF- 1 DCGLs for Soil Revision 01 3.10. DTE site meteorological data (10 m) X/Q and D/Q Joint Frequency Distribution Tables 2003 - 2007. | ||
Details on reviews, benchmarking, verification, and validation for the RESRAD code are summarized in Sections 5.1-5.4 of RESRAD User's Manual (ref. 3.3).The RESidual RADioactivity (RESRAD) model and computer code was developed by Scientists and Engineers at Argonne National Laboratory (ANL) as a multifunctional tool to assist in developing radiological criteria for unrestricted release and assessing the dose or risk associated with residual radioactive material. | 3.11. www.rssWeather.

All these pathways were applied for the DTE EF-I DCGL computer runs.In the previous Bartlett Engineering Calculation ENG-002 (ref. 3.17), the probabilistic modules in RESRAD Ver. 6.4 (ref. 3.14 and 3.15) were used to perform a sensitivity analysis to identify parameters that have the greatest impact on dose. The results from these RESRAD Ver. 6.4 Uncertainty Analysis output reports were used to determine which stochastic parameters were sensitive based on an absolute value of the PRCC exceeding the sensitivity threshold | 3.15.

(+/-0.25). The RESRAD Ver. 6.4 Interactive Report was then used to identify the 2 5 th or 7 5 th percentile values for the sensitive parameters shown in Table 1 and Attachment I (ref. 3.17).In this calculation ENG-004, the applicable parameters, including the values for the sensitive parameters, for each of the 25 nuclides of concern at DTE EF-Iwere inputed into the RESRAD software. | 3.16.

To calculate the DCGLs, it was assumed that the DTE EF- 1 decommissioning dose limit, DLTEDE, will be set at 25 mrem/yr which is the NRC's dose criteria established in 10CFR20.1403 (see 5.1.5 below). The single nuclide DCGL, for the nuclides of concern at DTE EF-1 were calculated using the equation below: DCGLi = DL TEDE/PMDi. | 3.18.

Sandy loam was assumed to be the types of soil in the vadose and saturated zone (ref. 3.6 & 3.8).5.1.2. Radionuclides of Concern. Twenty-five radionuclides were assumed for the Fermi 1 site: Ag-108m, Am241, C-14, Co-60, Cm-242, Cm-243, Cs-134, Cs-137, Eu-152, Eu-154, Eu-155, Fe-55, H-3, Mn-54, Na-22, Nb-94, Ni-59, Ni-63, Pu-238, Pu239, Pu-240, Pu-241, Sb-125, Sr-90, and Tc-99. This list of nuclides of concern was provided by the client for this contract i.e., DTE.5.1.3. Resident Farmer Scenario:The dose model used to perform the sensitivity analyses is based upon the Resident Farmer Scenario defined in NUREG/CR-5512 Volume 3 (Ref. 3.2). The average member of the critical group is the resident farmer that lives on the plant site, grows all or a portion of his / her diet onsite, and drinks water from a groundwater source onsite. The potential pathways used to estimate human radiation exposure resulting from residual radioactivity in the soil for this scenario includes the following: | : 4. METHOD OF CALCULATION The operability of the RESRAD Version 6.4 code was verified on each computer used for code executions in accordance with Bartlett Engineering procedure ENG-AP-02, Verification of Software Operability (ref. 3.13). The RESRAD User's manual (ref. 3.3) provided guidance for code operation and execution. The RESRAD code has undergone extensive review, benchmarking, verification, and validation.

The RESRAD computer code is a pathway analysis model designed to evaluate the potential radiological dose associated with residual radioactive material for a defined receptor scenario: in this case resident farmer.

Conceptual Model: EF-I Protected Area GeoHydrology: | Bartlett Engineering Calculation ENG-004 Calculation of DTE EF- I DCGLs for Soil Revision 01 ingestion of aquatic foods, and 8) inadvertant ingestion of soil contaminates. All these pathways were applied for the DTE EF-I DCGL computer runs. | ||
The conceptual hydrological model for this resident farmer scenario has three geological strata: 1) a contaminated zone, 2) an uncontaminated unsaturated zone, and 3) a saturated zone (ref.3.6). The residual radioactive material was assumed to be contained in the contaminated zone assumed equivalent in size to the EF-I Protected Area (see Figure 1). The contaminated zone was assumed to include only top soil (0 to 15 cm deep): It was assumed that no cover material exists over the contaminated zone.The soil between the topsoil and the groundwater table, namely the unsaturated zone, is initially uncontaminated. | In the previous Bartlett Engineering Calculation ENG-002 (ref. 3.17), the probabilistic modules in RESRAD Ver. 6.4 (ref. 3.14 and 3.15) were used to perform a sensitivity analysis to identify parameters that have the greatest impact on dose. The results from these RESRAD Ver. 6.4 Uncertainty Analysis output reports were used to determine which stochastic parameters were sensitive based on an absolute value of the PRCC exceeding the sensitivity threshold (+/-0.25). The RESRAD Ver. 6.4 Interactive Report was then used to identify the 2 5 th or 7 5 th percentile values for the sensitive parameters shown in Table 1 and Attachment I (ref. 3.17). | ||
On July 1, 2007, grain size distributions were determined for seven soil samples obtained near the Protected Area fence at the EF-1 site. The results indicated that the soil collected from the unsaturated zone is classified using the USDA method as sandy loam (ref. 3.8).The third zone is the saturated zone. It is assumed that the ground water is initially uncontaminated. | In this calculation ENG-004, the applicable parameters, including the values for the sensitive parameters, for each of the 25 nuclides of concern at DTE EF-Iwere inputed into the RESRAD software. The probablalistic module of RESRAD software was used to compute the single nuclide DCGLs. The Peak of the Mean Doses, PMDi ,were calculated by RESRAD ver. 6.4. The Peak of the Mean Dose result from each of the Uncertainty Reports was extracted. To calculate the DCGLs, it was assumed that the DTE EF- 1 decommissioning dose limit, DLTEDE, will be set at 25 mrem/yr which is the NRC's dose criteria established in 10CFR20.1403 (see 5.1.5 below). The single nuclide DCGL, for the nuclides of concern at DTE EF-1 were calculated using the equation below: | ||
The depth of the groundwater table is variable at EF-1, but the average depth to groundwater as measured in 2005 and 2006 was 6.5 feet or 1.8 meters (see section 6.1.20). The soil in the saturated zone is sandy loam (see section 5.1.1).5.1.5. DTE EF-1 Decommissioning Dose Limit: The DTE Dose Limit for decommissioning can be set at the NRC's 10CFR20.1402 (ref 3.12) dose criteria which states that a site is considered acceptable for unrestricted use if the residual radioactivity that is distinguisable from background radiation results in a dose to an average member of the critical group that does not exceed 25 mrem/yr and.... Therefore, it is assumed that the DTE EF-1 dose limit will be set at 25 mrem/yr or below.5.2. Inputs Attachment I summarizes the parameter name, type, priority, treatment, values/distribution and the reference source that provides the bases for each input parameter used for the DTE EF-1 soil DCGL development. | DCGLi = DL TEDE/PMDi. | ||
Table I lists the sensitive parameters that were identified in the sensitivty analysis and the associated sensitive parameter values (ref. 3.17). These sensitive parameters, as well as, the the site specific and other selected values will be used for the soil DCGL input parameters. | : 5. ASSUMPTIONS AND INPUT 5.1. Assumptions 5.1.1.

The field capacity is the ratio of the volume of water retained in the soil sample, after all drainage has ceased, to the total volume of the soil sample. Equation 4.4 of ref. 3.1 relates Total and Effective Porosities to Field Capacity as follows: Effective Porosity = Total Porosity -Field Capacity Rearranging this equation: Field Capacity = Total Porosity -Effective Porosity The total porosity of 0.410 and the effective porosity value of 0.346 were used for each of the three zones. These values are the mean values of the NUREG/CR-6697 distributions for sandy loam.Therefore the field capacity is approximately: | - Soil containing residual radioactivity. | ||
Field Capacity = 0.4 10 -0.346 = 0.064 6,1.5 Runoff Coefficients Table 10.1 of ref. 3.1 provides the equation below to calculate the Runoff Coefficient, Cr, for an agricultural environment. | 5.1.4. Conceptual Model: EF-I Protected Area GeoHydrology: The conceptual hydrological model for this resident farmer scenario has three geological strata: 1) a contaminated zone, 2) an uncontaminated unsaturated zone, and 3) a saturated zone (ref. | ||
Table 10.1, Runoff Coefficient Values, also lists values for cl, | 3.6). The residual radioactive material was assumed to be contained in the contaminated zone assumed equivalent in size to the EF-I Protected Area (see Figure 1). The contaminated zone was assumed to include only top soil (0 to 15 cm deep): It was assumed that no cover material exists over the contaminated zone. | ||
The conservative value of 0.1 was selected for C, since the DTE EF-1 site has relatively flat terrain.C,. | The soil between the topsoil and the groundwater table, namely the unsaturated zone, is initially uncontaminated. On July 1, 2007, grain size distributions were determined for seven soil samples obtained near the Protected Area fence at the EF-1 site. The results indicated that the soil collected from the unsaturated zone is classified using the USDA method as sandy loam (ref. 3.8). | ||
Cr= 1 -0.3 -0.4- 0.1 = 0.2 6.1.6. Watershed Area for Nearby Streams and Ponds The Detroit Edison EF 2 Final Safety Analysis Report (ref. 3.5) states in section 2.4.1.2.2 that "The Fermi site is in the Swan Creek drainage basin. The watershed is an area of 109 square miles, elongated in shape from northwest to southeast. | The third zone is the saturated zone. It is assumed that the ground water is initially uncontaminated. The depth of the groundwater table is variable at EF-1, but the average depth to groundwater as measured in 2005 and 2006 was 6.5 feet or 1.8 meters (see section 6.1.20). The soil in the saturated zone is sandy loam (see section 5.1.1). | ||
The basin is about 25 miles long with a maximum topographic relief of about .130 ft". Converting the watershed area of 109 square miles to square meters.Area = 109 mi2 x 2.59 kmi2/ mi | 5.1.5. DTE EF-1 Decommissioning Dose Limit: The DTE Dose Limit for decommissioning can be set at the NRC's 10CFR20.1402 (ref 3.12) dose criteria which states that a site is considered acceptable for unrestricted use if the residual radioactivity that is distinguisable from background radiation results in a dose to an average member of the critical group that does not exceed 25 mrem/yr and.... Therefore, it is assumed that the DTE EF-1 dose limit will be set at 25 mrem/yr or below. | ||
Multiplying by 365.25 days/year gives a drinking water ingestion rate of 478.5 liters/yr. | 5.2.

The area of the contaminated zone was calculated by the AutoCAD software. The value for the area was documented in an e-mail from Martin C. Erickson, DTE EF-1 Licensee Termination Manager (ref. 3.9), RE: NOL divided.dwg dated June 18, 2008, as 7,855.06 square meters.

Length of Parallel The Length of Parallel is defined (Ref 3.1) as the maximum horizontal distance measured in the contaminated zone, from its up gradient edge to the down gradient edge, along the direction of the groundwater flow in the underlying aquifer. It was assumed that the area of the contaminated zone could be approximated by a circle with an area of 7,855 m2 . The diameter of the circle is equivalent to the length of parallel and is calculated as follows: | |||
Area of a Circle A=7rr2 Where A is the Area in m2 and r is the radius in meters. | |||
r =50 m D = 2 x r =2*50 D= 100m Therefore, the length of parallel is 100 m. | |||

Contaminated Zone Erosion Rate The slope of the contaminated zone was determined from Figure 9 in Ref 3.6 entitled Groundwater Elevation Map February 7, 2006 Detroit Edison Fermi I (reproduced here as Figure 2). The line extending perpendicular from the contour line between MW- EFT-IOS and MW-EF-8S is a run of 313 feet with a decreasing change in elevation from 588.5 feet to 582.5 feet. The slope at the DTE Contaminated Area is 6ft per 313ft, which corresponds to a 1.9% slope.

The data in Table 2 below was generated using NUREG/CR-6697's row-crop Erosion Rate of 6.0 x 0-4 for a 2 % slope. As recommended in this section of NUREG/CR-6697, the remaining Erosion Rates were calculated for 5, 10 and 15 percent slopes using the rate increase factors on p. 3-25. | |||

The field capacity is the ratio of the volume of water retained in the soil sample, after all drainage has ceased, to the total volume of the soil sample. Equation 4.4 of ref. 3.1 relates Total and Effective Porosities to Field Capacity as follows: | |||
Effective Porosity = Total Porosity - Field Capacity Rearranging this equation: | |||
Field Capacity = Total Porosity - Effective Porosity The total porosity of 0.410 and the effective porosity value of 0.346 were used for each of the three zones. These values are the mean values of the NUREG/CR-6697 distributions for sandy loam. | |||
Therefore the field capacity is approximately: | |||
Field Capacity = 0.4 10 - 0.346 = 0.064 6,1.5 Runoff Coefficients Table 10.1 of ref. 3.1 provides the equation below to calculate the Runoff Coefficient, Cr, for an agricultural environment. Table 10.1, Runoff Coefficient Values, also lists values for cl, c2 and c3 for various environments: The conservative value of 0.1 was selected for C, since the DTE EF-1 site has relatively flat terrain. | |||
C,. Ii-c 1 -c 2 -c 3 cl = 0.3 for Flat land with an average slope between 0.3 and 0.9 m/mi. | |||
C2 = 0.4 for open sandy loam as identified at the EF-1 Protected Area (Ref. 3.8). | |||
C3 = 0.1 for cultivated lands which also fits the scenario for the EF- 1 site. | |||
Therefore the runoff coefficient is approximately: | |||
Cr= 1 - 0.3 - 0.4- 0.1 = 0.2 6.1.6. Watershed Area for Nearby Streams and Ponds The Detroit Edison EF 2 Final Safety Analysis Report (ref. 3.5) states in section 2.4.1.2.2 that "The Fermi site is in the Swan Creek drainage basin. The watershed is an area of 109 square miles, elongated in shape from northwest to southeast. The basin is about 25 miles long with a maximum topographic relief of about .130 ft". Converting the watershed area of 109 square miles to square meters. | |||

Fraction of Time Spent Outdoor NUREG/CR-5512 (Ref. 3.2) Table 6.87 provides default values for the residential parameters for the exposure period outdoors of 40.2 days and the exposure period gardening of 2.92 which yields a sum of 42.92 days outdoor.

Bartlett Engineering Calculation ENG-004 Calculation of DTE EF-1 DCGLs for Soil Revision 01
- 1. PURPOSE The purpose of this calculation is to develop derived concentration guideline levels (DCGLs) for Detroit Edison's (DTE) Enrico Fermi 1 (EF-1) Fast Breeder Reactor located in Newport, Michigan.
This calculation is part of the scope of work defined in the DTE Contract No. 4400001090 associated with DTE Fermi 1 DCGL Development.
Revision 1 is being performed in order to correct the nuclide used in the DCGL RESRAD input file for Nb-94. The Revision 0 input file used Nb-95 instead of Nb-94. This revision used Nb-94 and corrected the Peak of the Mean Dose/DCGL. Minor typographical errors have also been corrected.
- 2. APPLICABILITY This calculation addresses only the development of DCGLs for soils at the DTE EF 1 site using the resident farmer scenario and the RESRAD Version 6.4 software.

- 4. METHOD OF CALCULATION The operability of the RESRAD Version 6.4 code was verified on each computer used for code executions in accordance with Bartlett Engineering procedure ENG-AP-02, Verification of Software Operability (ref. 3.13). The RESRAD User's manual (ref. 3.3) provided guidance for code operation and execution. The RESRAD code has undergone extensive review, benchmarking, verification, and validation. Details on reviews, benchmarking, verification, and validation for the RESRAD code are summarized in Sections 5.1-5.4 of RESRAD User's Manual (ref. 3.3).
The RESidual RADioactivity (RESRAD) model and computer code was developed by Scientists and Engineers at Argonne National Laboratory (ANL) as a multifunctional tool to assist in developing radiological criteria for unrestricted release and assessing the dose or risk associated with residual radioactive material. The RESRAD computer code is a pathway analysis model designed to evaluate the potential radiological dose associated with residual radioactive material for a defined receptor scenario: in this case resident farmer. Eight environmental pathway models are considered in this software application: 1) direct radiation exposure, 2) inhalation of airborne dust,
- 3) ingestion of plants, 4) ingestion of meat, 5) ingestion of milk, 6) ingestion of groundwater, and 7).
Page 2 of 24
Bartlett Engineering Calculation ENG-004 Calculation of DTE EF- I DCGLs for Soil Revision 01 ingestion of aquatic foods, and 8) inadvertant ingestion of soil contaminates. All these pathways were applied for the DTE EF-I DCGL computer runs.
In the previous Bartlett Engineering Calculation ENG-002 (ref. 3.17), the probabilistic modules in RESRAD Ver. 6.4 (ref. 3.14 and 3.15) were used to perform a sensitivity analysis to identify parameters that have the greatest impact on dose. The results from these RESRAD Ver. 6.4 Uncertainty Analysis output reports were used to determine which stochastic parameters were sensitive based on an absolute value of the PRCC exceeding the sensitivity threshold (+/-0.25). The RESRAD Ver. 6.4 Interactive Report was then used to identify the 2 5 th or 7 5 th percentile values for the sensitive parameters shown in Table 1 and Attachment I (ref. 3.17).
In this calculation ENG-004, the applicable parameters, including the values for the sensitive parameters, for each of the 25 nuclides of concern at DTE EF-Iwere inputed into the RESRAD software. The probablalistic module of RESRAD software was used to compute the single nuclide DCGLs. The Peak of the Mean Doses, PMDi ,were calculated by RESRAD ver. 6.4. The Peak of the Mean Dose result from each of the Uncertainty Reports was extracted. To calculate the DCGLs, it was assumed that the DTE EF- 1 decommissioning dose limit, DLTEDE, will be set at 25 mrem/yr which is the NRC's dose criteria established in 10CFR20.1403 (see 5.1.5 below). The single nuclide DCGL, for the nuclides of concern at DTE EF-1 were calculated using the equation below:
DCGLi = DL TEDE/PMDi.
- 5. ASSUMPTIONS AND INPUT 5.1. Assumptions 5.1.1. Soil: Soil is defined as unconsolidated earth material including rubble and debris that may be present. Sandy loam was assumed to be the types of soil in the vadose and saturated zone (ref. 3.6 & 3.8).
5.1.2. Radionuclides of Concern. Twenty-five radionuclides were assumed for the Fermi 1 site: Ag-108m, Am241, C-14, Co-60, Cm-242, Cm-243, Cs-134, Cs-137, Eu-152, Eu-154, Eu-155, Fe-55, H-3, Mn-54, Na-22, Nb-94, Ni-59, Ni-63, Pu-238, Pu239, Pu-240, Pu-241, Sb-125, Sr-90, and Tc-99. This list of nuclides of concern was provided by the client for this contract i.e., DTE.
5.1.3. Resident Farmer Scenario:The dose model used to perform the sensitivity analyses is based upon the Resident Farmer Scenario defined in NUREG/CR-5512 Volume 3 (Ref. 3.2). The average member of the critical group is the resident farmer that lives on the plant site, grows all or a portion of his / her diet onsite, and drinks water from a groundwater source onsite. The potential pathways used to estimate human radiation exposure resulting from residual radioactivity in the soil for this scenario includes the following:
Page 3 of 24
Bartlett Engineering Calculation ENG-004 Calculation of DTE EF-I DCGLs for Soil Revision 01
- Direct exposure to external radiation from soil containing residual radioactivity;
- Internal dose from inhalation of airborne radionuclides;
" Internal dose from ingestion of:
- Plant foods grown in the soil material containing residual radioactivity;
- Meat and milk from livestock fed with fodder grown in soil containing residual radioactivity and water containing residual radioactivity;
- Drinking water containing residual radioactivity from a well;
- Aquatic food from a pond containing residual radioactivity; and
- Soil containing residual radioactivity.
5.1.4. Conceptual Model: EF-I Protected Area GeoHydrology: The conceptual hydrological model for this resident farmer scenario has three geological strata: 1) a contaminated zone, 2) an uncontaminated unsaturated zone, and 3) a saturated zone (ref.
3.6). The residual radioactive material was assumed to be contained in the contaminated zone assumed equivalent in size to the EF-I Protected Area (see Figure 1). The contaminated zone was assumed to include only top soil (0 to 15 cm deep): It was assumed that no cover material exists over the contaminated zone.
The soil between the topsoil and the groundwater table, namely the unsaturated zone, is initially uncontaminated. On July 1, 2007, grain size distributions were determined for seven soil samples obtained near the Protected Area fence at the EF-1 site. The results indicated that the soil collected from the unsaturated zone is classified using the USDA method as sandy loam (ref. 3.8).
The third zone is the saturated zone. It is assumed that the ground water is initially uncontaminated. The depth of the groundwater table is variable at EF-1, but the average depth to groundwater as measured in 2005 and 2006 was 6.5 feet or 1.8 meters (see section 6.1.20). The soil in the saturated zone is sandy loam (see section 5.1.1).
5.1.5. DTE EF-1 Decommissioning Dose Limit: The DTE Dose Limit for decommissioning can be set at the NRC's 10CFR20.1402 (ref 3.12) dose criteria which states that a site is considered acceptable for unrestricted use if the residual radioactivity that is distinguisable from background radiation results in a dose to an average member of the critical group that does not exceed 25 mrem/yr and.... Therefore, it is assumed that the DTE EF-1 dose limit will be set at 25 mrem/yr or below.
5.2. Inputs Attachment I summarizes the parameter name, type, priority, treatment, values/distribution and the reference source that provides the bases for each input parameter used for the DTE EF-1 soil DCGL development. Table I lists the sensitive parameters that were identified in the sensitivty analysis and the associated sensitive parameter values (ref. 3.17). These sensitive parameters, as well as, the the site specific and other selected values will be used for the soil DCGL input parameters.

- 6. CALCULATIONS AND RESULTS 6.1. Calculations Some parameter values listed in Attachment 1 required calculations. These calculations are documented below.
641.1. Area of the Contaminated Zone Figure 1, Area of the Contaminated Zone (DTE Drawing) was generated with AutoCAD.
The area of the contaminated zone was calculated by the AutoCAD software. The value for the area was documented in an e-mail from Martin C. Erickson, DTE EF-1 Licensee Termination Manager (ref. 3.9), RE: NOL divided.dwg dated June 18, 2008, as 7,855.06 square meters. The area of the contaminated zone is assumed equivalent to the area of the ERI Protected Area (outlined with a bold line in Figure 1).

Bartlett Engineering Calculation ENG-004 Calculation of DTE EF- I DCGLs for Soil Revision 01 Figure 1- EF-1 Area of Contaminated Zone 6.1.2. Length of Parallel The Length of Parallel is defined (Ref 3.1) as the maximum horizontal distance measured in the contaminated zone, from its up gradient edge to the down gradient edge, along the direction of the groundwater flow in the underlying aquifer. It was assumed that the area of the contaminated zone could be approximated by a circle with an area of 7,855 m2 . The diameter of the circle is equivalent to the length of parallel and is calculated as follows:
Area of a Circle A=7rr2 Where A is the Area in m2 and r is the radius in meters.
r =50 m D = 2 x r =2*50 D= 100m Therefore, the length of parallel is 100 m.

Bartlett Engineering Calculation ENG-004 Calculation of DTE EF- I DCGLs for Soil Revision 01 6.1.3. Contaminated Zone Erosion Rate The slope of the contaminated zone was determined from Figure 9 in Ref 3.6 entitled Groundwater Elevation Map February 7, 2006 Detroit Edison Fermi I (reproduced here as Figure 2). The line extending perpendicular from the contour line between MW- EFT-IOS and MW-EF-8S is a run of 313 feet with a decreasing change in elevation from 588.5 feet to 582.5 feet. The slope at the DTE Contaminated Area is 6ft per 313ft, which corresponds to a 1.9% slope. Figure 2 shows the monitoring wells, MW- EFT-lOS and MW-EF-8S, that were used for their ground elevation data.

Bartlett Engineering Calculation ENG-004 Calculation of DTE EF-1 DCGLs for Soil Revision 01 Data from NUREG/CR-6697, Attachment C, Section 3.8, 2nd paragraph of the Discussion Section on pages 3-25 & 3-26, was used to select the appropriate Erosion Rate that corresponds to the DTE EF-1 Site slope of 1.9%.
The data in Table 2 below was generated using NUREG/CR-6697's row-crop Erosion Rate of 6.0 x 0-4 for a 2 % slope. As recommended in this section of NUREG/CR-6697, the remaining Erosion Rates were calculated for 5, 10 and 15 percent slopes using the rate increase factors on p. 3-25.
Table 2 displays the results of the erosion rate calculations.
Table 2 - Erosion Rate Percent Erosion Rate Slope (m/y) 2 6.OE-4 5 1.8E-3 10 4.2E-3 15 9.OE-3 Using the above Erosion Rate/Slope data the DTE EF- 1 site slope of - 1.9 % corresponds to an Erosion Rate of approximately 6 x 10-4 m/y.

Bartlett Engineering Calculation ENG-004 Calculation of DTE EF- I DCGLs for Soil Revision 01 6.1.4 Field Capacity: Contaminated Zone, Unsaturated zone and Saturated zone ANL/EAIS-8, Data Collection Handbook to Support Modeling the Impacts of Radioactive Material in Soil, (ref. 3.1) defines the relationship of field capacity (residual water content) to effective porosity. The field capacity is the ratio of the volume of water retained in the soil sample, after all drainage has ceased, to the total volume of the soil sample. Equation 4.4 of ref. 3.1 relates Total and Effective Porosities to Field Capacity as follows:
Effective Porosity = Total Porosity - Field Capacity Rearranging this equation:
Field Capacity = Total Porosity - Effective Porosity The total porosity of 0.410 and the effective porosity value of 0.346 were used for each of the three zones. These values are the mean values of the NUREG/CR-6697 distributions for sandy loam.
Therefore the field capacity is approximately:
Field Capacity = 0.4 10 - 0.346 = 0.064 6,1.5 Runoff Coefficients Table 10.1 of ref. 3.1 provides the equation below to calculate the Runoff Coefficient, Cr, for an agricultural environment. Table 10.1, Runoff Coefficient Values, also lists values for cl, c2 and c3 for various environments: The conservative value of 0.1 was selected for C, since the DTE EF-1 site has relatively flat terrain.
C,. Ii-c 1 -c 2 -c 3 cl = 0.3 for Flat land with an average slope between 0.3 and 0.9 m/mi.
C2 = 0.4 for open sandy loam as identified at the EF-1 Protected Area (Ref. 3.8).
C3 = 0.1 for cultivated lands which also fits the scenario for the EF- 1 site.
Therefore the runoff coefficient is approximately:
Cr= 1 - 0.3 - 0.4- 0.1 = 0.2 6.1.6. Watershed Area for Nearby Streams and Ponds The Detroit Edison EF 2 Final Safety Analysis Report (ref. 3.5) states in section 2.4.1.2.2 that "The Fermi site is in the Swan Creek drainage basin. The watershed is an area of 109 square miles, elongated in shape from northwest to southeast. The basin is about 25 miles long with a maximum topographic relief of about .130 ft". Converting the watershed area of 109 square miles to square meters.
2 8 2 Area = 109 mi2 x 2.59 kmi2/ mi x 106 M / km = 2.82 x 10 m 2 2 Page 14 of 24
Bartlett Engineering Calculation ENG-004 Calculation of DTE EF- I DCGLs for Soil Revision 01 6.1.7. Fraction of Time Spent Indoors NUREG/CR-5512 (ref. 3.2) Table 6.87 provides default values for the residential parameters the exposure period indoors is given as 240 days. Dividing by 365.25 days/year gives a fraction of time spent indoors of 0.6571.
6.1.8. Fraction of Time Spent Outdoor NUREG/CR-5512 (Ref. 3.2) Table 6.87 provides default values for the residential parameters for the exposure period outdoors of 40.2 days and the exposure period gardening of 2.92 which yields a sum of 42.92 days outdoor. Dividing by 365.25 days/year gives a fraction of time spent outdoors of 0.1175.
6.1.9. Inhalation Rate:
NUREG/CR-6697 (ref 3.4) in Attachment C section 5.1 states "the ICRP's best estimate, which is based on 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> of light activity and 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of rest as 23 m 3/d for adult males." This results an annual inhalation rate of approximately 8400 m 3/y.
6.1.10 Soil Ingestion Rate NUREG/CR-5512 (Ref. 3.2) Table 6.87 provides default values for the residential parameters the soil ingestion rate is given as 0.05 g/d. Multiplying by 365.25 days/year gives a soil ingestion rate of 18.26 g/yr.
6.1.11 Drinking Water Intake NUREG/CR-5512 (ref. 3.2) Table 6.87 provides default values for the residential parameters the drinking water ingestion rate is given as 1.31 liters/d. Multiplying by 365.25 days/year gives a drinking water ingestion rate of 478.5 liters/yr.
6.1.12 Miscellaneous Consumption Rates NUREG/CR-5512 (ref. 3.2) Table 6.87 provides default values for the residential parameters for other ingestion rates used by this resident farmer scenario. These parameters and the ingestion rates are listed in Table 3.

Bartlett Engineering Calculation ENG-004 Calculation of DTE EF- I DCGLs for Soil Revision 01 6.1.13 C-14 Evasion Flux Rate for Soil The RESRAD Users Manual (ref. 3.3) provides on p L-16 the value for the C-14 evasion loss rate constant of 22 1/ yr. RESRAD requires that this parameter be expressed in units of 1/sec.
Converting 22 1/yr to inverse seconds by dividing by 31,557,600 sec/y gives approximately, 7 x 10-7 1/sec.
6.1.14 C-12 Evasion Flux Rate for Soil The RESRAD Users Manual (ref. 3.3) provides on p L-16 the value for the C-12 evasion rate factor of 0.0032 l/y. RERAD requires that this parameter be expressed in units of 1/sec. Converting 0.0032 per year to inverse seconds by dividing by 31,557,600 sec/y gives 1.01 x 10-10 1/sec.
6.1.15 Humidity in Air The technical article entitled, "Regional and Site-Specific Absolute Humidity Data for Use in Tritium Dose Calculations", which is found in Health Physics, Vol.39, pp. 318-320, 1980 (ref. 3.7) provides a table of absolute humidity for selected locations in the United States. These values were calculated from data from the National Oceanic and Atmospheric Administration, 1977, 3
Climatological Data, Annual Summary, volume 28, U.S. Dept. of Commerce. The value of 4.6 g/m (Detroit, Michigan) was chosen from Table 1 of this technical article for the RESRAD humidity in air parameter.
6.1.16 Average Annual Wind Speed The joint frequency distributions from 2003 to 2007 for Detroit Edison's Enrico Fermi site contain wind speed and direction data (Ref 3.10). These data were used to calculate the average annual wind speed. The mid-range value and the associated frequency for each of the wind speed ranges over this five year period are shown in Table 4. An average wind speed was calculated by sunming the product of the mid-range value for each range and the fraction of time the wind was recorded to be within the range. A value of 2.91 m/s was calculated for the average annual wind speed.

These rain guage measurements were taken over the period 1971 to 2000 (ref. 3.11). This information was based on precipitation data from the the website called rssWeather.com.

The precipitation rate was assigned a value of 0.84 meters/year 6.1.18 Irrigation Rate (Evapotranspiration and Runoff Coefficients)
NUREG/CR-6697 Attachment C, Section 4.3 discusses the Irrigation Rate in terms of the Evapotranspiration Coefficient. Equation 4.3-1 expresses the Evapotranspiration Coefficient as:
Ce = ETr (1-Cr)(Pr) + IRr Where: ETr = the Evapotransporation Rate (m/y)
Pr = the Precipitation Rate (m/y)
IRr = the Irrigation Rate (m/y) and Cr = the Runoff Coefficient.
Page 18 of 24
Bartlett Engineering Calculation ENG-004 Calculation of DTE EF- I DCGLs for Soil Revision '01 Rearranging this equation, the Irrigation Rate can be expressed as:
IRr = ETr - (1-Cr)(Pr)
Ce The input values for the variables in the equation above follow:
- 1. The Average Annaul Potential Evapotranspiration Rate, ETr, in inches per year is provided in ANL/EIS-8 (Ref 3.1) Figure 12.1. This reference provides a map of the United States showing the regional Evapotranspiration Rates. The midpoint of the average anuual evapotranspiration rate for the region around Newport, Michigan is 30 inches/year.
Converting to m/yr by multipling by 2.54 cm/in and dividing by 100 cm/m yields 0.762 m/yr for the ETr, evapotranspiration rate.
- 2. The Precipitation Rate, Pr, has been assigned a site-specific value of 0.84 m/yr as discussed in item 6.1.17 above.
- 3. The Runoff Coefficient Values, Cr, has been assigned a site-specific value of 0.2 as discussed in item 6.1.5 above
- 4. The Evapotranspiration Coefficient, Ce, is defined in NUREG/CR-6697, Attachment C, Section 4.3 as the ratio of the total volume of water (a combination of evaporation from soil surfaces and transpiration .from vegetation) transferred to the atmosphere to the total volume of water available within the root zone of the soil. This NUREG/CR recommends the use of a uniform distribution with a minimum and maximum values of 0.5 and 0.75, respectively.
Making the appropriate substitution of minimum and maximum values of Ce into the rearranged equation above results in the following range for the Irrigation Rate, IRr, shown in Table 6 below.
Table 6 -Irrigation Rate Variable min value max value Evapotranspiration Rate (m/y) ETr 0.762 0.762 Precipitation Rate (m/y) Pr 0.84 0.84 Runoff Coefficient Cr 0.2 0.2 Evapotranspiration Coefficient Ce 0.75 0.5 Irrigation Rate (m/y) IRr 0.344 0.852 The calculated minimum and maximum IRr values are 0.344 and 0.852 m/y, respectively. A uniform distribution was assigned for this parameter and as previously mentioned a positive input correlation to the Well Pumping Rate was assigned based on the guidance in NUREG/CR-6697 (ref.
3.4) and NUJREG/CR-6676 (ref. 3.15).
6.1.19 Well Pumping Rate Page 19 of 24
Bartlett Engineering Calculation ENG-004 Calculation of DTE EF-1 DCGLs for Soil Revision 01 NUREG/CR-6697 (ref. 3.4), Attachment C, Section 3.10 states that "A site-specific input distribution for well pumping rate can be determined as the sum of individual water needs." A uniform distribution was assigned for this parameter with a positive correlation to the Irrigation Rate. The household use component is calculated from the domestic use in Table 7:
Table 7 - Resident Farmer Water Use Water Use Component (Family of four) Median Minimum Maximum Household* (m 3/y) 374 374 374 3

- EPA recommends (ref 3.18) a Household Water Use for a family of four persons of 272 gallons per day (272 gal/day x 3.79E-3 gal/mi3 x 365.25day/y = 376 m 3/y). The household use is equivalent to 376 m 3/y minus the drinking water component of 1.91 m 3/y which equals 374 m 3/y.
- EPA also recommends for Drinking Water the use of 478 L/y per individual (478 L/y-Ind x 4 Ind x lm 3/1000L = 1.91 m /y).
The well pumping intake rates which use a uniform distribution will be assigned the following values for the statistical parameters: median 1649 m 3/y, minimum = 1141 m 3/y and maximum =
2157 m3/y.
6.1.20. Unsaturated Zone 1, Thickness The Golder Associates Report on Groundwater Characterization for Enrico Fermi I License Termination (ref. 3.6) provided data from Groundwater Elevation measurements performed on 11/17/03 through 12/11/06. The groundwater elevation data from 9/22/05 to 12/11/06 were used to establish average depth to groundwater since this period had full data sets forthe shallow monitoring wells.

6.2 Results This revision includes only selected pages from the RESRAD runs for Nb-94 in Attachment 2. The results of the RESRAD runs (selected pages) for each of the other 24 nuclides are provided in of Revision 0. As mentioned in section 4, one of the results from the RESRAD software is the Peak of the Mean Dose, PMDi. The Peak of the Mean Dose for the average member of the critical group for the 25 nuclides are listed in the second column of Table 10.
The DCGLs are the concentrations of residual radioactive material that are derived using the RESRAD pathway analysis to correspond to the dose limit established by DTE for Fermi I decommissioning (Section 5.1.5). The single nuclide DCGLi for the nuclides of concern at DTE EF-1 can be calculated using the equation below, the 25 mrem/yr Dose Limit, DL TEDE, and the Peak of the Mean Dose,. PMDi, in mrem/yr per pCi/g:
DCGLI = DL TEDE/PMDi.
The single nuclide DCGLs are listed in the third column of Table 10.
