BARTLETT ENGINEERING CALCULATION Calculation Number: ENG-002 Revision Number: 001 Calculation Title: Sensitivity Analysis for Enrico Fermi 1 Derived Concentration Guidelines Level for Soil..ionne -Preparer: Reviewer:

46,:,o Approval:{ Corporate Project Manager Approv al: ~2Q'~.~I Director of Quality Ass~ance Date ?/s/Date Date ____ -__Date: E-"2"'-e5 Bartlett.60 Industrial Park Road Plymouth, MA 02360 A Bartlett Engineering Calculation Calculation No. ENG-002 Sensitivity Analysis for DTE EF-1 DCGLs for Soil Rev. 1 1. PURPOSE The purpose of this calculation is to identify which stochastic parameters used in the RESRAD computer code have the greatest influence on the calculated dose, i.e., peak of mean dose. The results of this calculation will support the development of the Derived Concentration Guideline Levels (DCGLs) that are being developed 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.

Revision 1 to this calculation was performed to correct input errors for Am-241, Sb-125 and Sr-90.For Am-241 the Kd distributions and associated statistical parameters for the unsaturated zone (non contaminated strata) and the saturated zone were added to the sensitivity analysis input data set. For the Sb-125 and Sr-90, the distribution for the mass loading for inhalation was changed from truncated log normal to continuous linear.In addition, this revised calculation clarified the footnotes in Table 7 in section 6.1.19 Well Pumping Rates. Also, the filenames for the RESRAD Input Parameters that were listed in the first column of Table 9 were replaced with the filenames of the RESRAD Uncertainty Reports.2. APPLICABILITY This calculation addresses only the sensitivity analysis for input parameters for the resident farmer scenario that will be used to develop the DCGLs for soils at the DTE EF 1 site.3.

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 Page 2 of 28./

Bartlett Engineering Calculation Calculation No. ENG-002 Sensitivity Analysis for DTE EF-1 DCGLs for Soil Rev. I 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)ingestion of aquatic foods, and 8) inadvertant ingestion of soil contaminates.

The code requires input for numerous parameters in order to calculate the dose via various exposure pathways to a hypothetical resident farmer living on the radioactive material in the soil. The probabilistic modules in RESRAD permit the user to perform a sensitivity analysis to identify parameters that have the greatest impact on dose. In addition, the probabilistic modules allow the evaluation of dose as a function of parameter distributions.

Monte Carlo simulations are executed using the Latin Hypercube Sampling techniques to. generate vectors for the input parameters.

The approach taken in this calculation for parameter selection is illustrated in Figure 1 and is summarized as follows-First SubTask: The initial parameter selection process is based on guidance provided in NUREG/CR-6676 (ref 3.15), NUREG/CR-6697 (ref. 3.4), and NUREG/CR-6692 (ref. 3.14). The set of initial input parameters are listed in the first column of Attachment 1 under the following categories:

  • Soil Concentration
  • Distribution Coefficients
  • Calculation Time* Contaminated Zone* Cover and Contaminated Zone Hydrological Data* Saturated Zone Hydrological Data* Unsaturated Zone Hydrological Data* Occupancy* Ingestion, Dietary* Ingestion, Non-dietary
  • Storage Times* Special Radionuclides (C-14)* Inhalation Dose Conversion Factors* Ingestion Dose Conversion Factors* Transfer Factors for Plants, Meat, Milk, Fish and Other Seafood Second Sub Task: Parameters were classified into three types: 1) behavioral (B), 2) metabolic (M), or 3) physical (P). The classification of initial parameters shown in column 2 of Attachment 1 are consistent-with those shown in NUREG/CR-6697 Attachment A (ref. 3.4). Behavioral parameters depend on the behavior of the receptor and the scenario definition.

Metabolic parameters are independent of the defined scenario, and represent the metabolic characteristics of the receptor.Physical parameters are those parameters that would not change if the receptor changed. Physical parameters are measurements of physical properties such as: the radioactive source, its size, its Page 3 of 28 Bartlett Engineering Calculation Calculation No. ENG-002 Sensitivity Analysis for DTE EF-1 DCGLs for Soil Rev. 1 location, as well as meteorological, geologic and hydrologic characteristics of the potentially contaminated site Third Sub Task: Next, the parameters were assigned priority rankings:

Priority 1 parameters are high priority; Priority 2 parameters are medium priority; and Priority 3 parameters are low priority.The priority rankings of initial parameters shown in column 3 of Attachment I are consistent with NUREG/CR-6697 Attachment B (ref. 3.4). Those rankings were adopted in this calculation.

The priority for the parameters was based on:* the relevance of the parameter in dose calculations,* the variability of the dose because of changes in the parameter value,* the parameter type, and* the availability of parameter-specific data.Fourth Sub Task: Input parameters are treated as either deterministic or stochastic based on whether a single value is assigned or a probability distribution is assigned.

The treatment type used is shown in column 4 of Attachment 1.After completing these subtasks, the next task was to assign deterministic values or distributions to each of the parameters.

The decision making process shown in Figure 1 entitled Parameter Selection Process was used to assign values/distributions and is summarized as follows: Behavioral and metabolic parameters are assigned values representative of the average member of the critical group, as appropriate.

Behavioral and metabolic parameters were treated as deterministic and were assigned values selected from NUREG/CR-5512, volume 3 (ref. 3.2), NUREG/CR-6697 (ref. 3.4), ANL/EAD-4 User's Manual for RESRAD Version 6 (ref. 3.3) or EPA FRG- 11 (ref. 3.16). Physical parameters for which site-specific data were available were assigned these site specific values or distributions from NUREG/CR-6697 (ref. 3.4). Physical parameters for which no site-specific measurements are available are identified and assigned conservative values as follows: 1) Priority 1 and 2 physical parameters were treated as stochastic and assigned probability distributions from NUREG/CR-6697 (ref. 3.4); 2) Priority 3 physical parameters were treated as deterministic and were assigned values from NUREG/CR-5512, Volume 3 (ref. 3.3), ANL/EAIS-8 (ref. 3.1), or the RESRAD default library.The values/distributions that were selected are shown in column 5 of Attachment

1. After completing the initial parameter selection process described above, RESRAD input files were generated for each radionuclide of concern. Input correlations were applied based on guidance in NUREG/CR-6676 (ref. 3.15). The following correlations were used for each code execution:
  • Total porosity and bulk density = -0.99 (contaminated zone, unsaturated and saturated zones);" Total porosity and effective porosity = 0.96 (unsaturated and saturated zones); and* Well Pumping rate and irrigation

= 0.96.Page 4 of 28 Bartlett Engineering Calculation Calculation No. ENG-002 Sensitivity Analysis for DTE EF-1 DCGLs for Soil Rev. 1 The sensitivity analyses were run using 2000 observations ahd 1 repetition.

The Latin Hypercube Sampling (LHS) technique was used to sample the probability distributions for each of the.stochastic input parameters.

The correlated or uncorrelated grouping option and a random seed of 1000 were used to preserve the prescribed correlations.

The RESRAD Ver. 6.4 output reports for the Uncertainty Analysis were reviewed to determine which stochastic parameters were sensitive based on an absolute value of the PRCC exceeding the sensitivity Threshold.

Next, the RESRAD Ver. 6.4 Interactive Report was used to identify the 2 5 th or 7 5 th percentile values for the sensitive parameters.

The 2 5 th and 7 5 th percentile values were obtained by using the Interactive Report feature in RESRAD and the following instructions:

1. Open the RESRAD file for the desired nuclide that was generated during the sensitivity runs.2. Select the "View Interactive Output" (blue bar graph) button on the RESRAD icon menu,.3. Click the "Results" tab in the interactive output window.4. Click down arrow on "Primary Object" box. Select "Peak Nuclide Dose" from the pull down menu.5. The desired nuclide will appear in the "Nuclide" box.6. Click on the "Graphics" tab. A graph of a distribution will appear.7. Click the down arrow on "Primary Object" box. Select "Input Vector" from the pull down menu. Click the down arrow on "Input Parameter" box. Select the desired parameter by scrolling through the choices in the pull down menu. The distribution will appear.8. Right click on the cumulative probability graph and select "Edit Chart Data." 9. Scroll down in the column labeled C2 and select 0.25 for 25th percentile values and 0.75 for 75th percentile values.10. Select the corresponding parameter value in Column C1.Page 5 of 28 Bartlett Engineering Calculation Sensitivity Analysis for DTE EF-l DCGLs for Soil Calculation No. ENG-002 Rev. 1 Figure 1 -Parameter Selection Process Inpt paaee Inu paamte Assign site-specific value or Assign site-specific value or distributionr or 75 Quantile distributioni or 25 Quantile I I Input paaee Input parameter value Page 6 of 28 Bartlett Engineering Calculation Calculation No. ENG-002 Sensitivity Analysis for DTE EF-1 DCGLs for Soil Rev. I 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.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:

a 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 watercontaining residual radioactivity;

-Drinking water containing residual radioactivity from a well;-Aquatic food from a pond containing residual radioactivity; and-Soil containing residual radioactivity.

4. Conceptual Model: EF-1 Protected Area GeoHydrology:

The conceptual hydrological model for this resident farmer scenario has three geological stratas: 1) a contaminated zone, 2) an unsaturated zone, and 3) a saturated zone. The residual radioactive material was assumed to be contained in the contaminated zone assumed equivalent in size to the EF-1 Protected Area (see Figure 2). The contaminated zone Was assumed to include only top soil (0 to 15 cm deep): It was assumed that no soil cover exist 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 sevensoil samples obtained near the Protected Area fence at the EF-I site (Attachment 2). The results indicated that the soil collected in the range 20 to 50 cm, i.e., 8" to 20" is Page 7 of 28 Bartlett Engineering Calculation Calculation No. ENG-002 Sensitivity Analysis for DTE EF-1 DCGLs for Soil Rev. 1 classifedusing the USDA method as sandy loam. The third zone isthe 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 as 6.5 feet (see section 6.1.20).5.2. Inputs Attachment 1 summarizes the parameter name, type, prioritiy, treatment, values/distribution and the reference source that provides the bases for each input parameter.

Some parameter values required calculations.

These calculations are documented below in section 6.1 Calculations.

6. CALCULATIONS AND RESULTS 6.1. Calculations 6.1.1. Area of the Contaminated Zone Figure 2, 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, 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 2).Figure 2 -EF-1 Area of Contaminated Zone r ...... ..............

Length of Parallel The Length of Parallel is defined in Ref 3.1 as is 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 2 could be approximated by a circle with an area of 7,855 m .The diameter of the circle is equivalent to the length of parallel and is calculated as follows: Area of a Circle A = 7t r2 2 Where A is the Area in m 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.6.1.3. Contaminated Zone Erosion Rate The slope of the contaminated zone was determined from Figure 9 in the Ref 3.6 entitled Groundwater Elevation Map February 7, 2006 Detroit Edison Fermi 1 (reproduced here as Figure 3). The line extending perpendicular from the contour line between MW- EFT-10S 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-1OS and MW-EF-8S, that were used for their ground elevation data.Page 9 of 28 Bartlett Engineering.

As recommended in this section of NUREG/CR-6697, the remaining Erosion Rates where calculated for 5, 10 and 15 percent slopes using the rate increase factors on p. 3-25.Table I displays the results of the erosion rate calculations.

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 = 0.410 -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, c 2 and c 3 for various environments:

Cr = 1- C1 -c 2 -c 3 l= 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).c 3 = 0.1 for cultivated lands which also fits the scenario for the EF-1 site.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 area of 109 square miles to square meters.Area = 109 mi x 2.59 km 2/ mi 2 x 106 m 2/ km 2 2.82 x 108 m 2 Page 13 of 28 Bartlett Engineering Calculation Calculation No. ENG-002 Sensitivity Analysis for EF-1 DCGLs for Soil Rev. 1 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 the-Exposure period outdoors is given as 40.2 days and the Exposure period gardening is 2.92 which yields a sum of 42.92 days outdoor. Dividing by 365.25 days/year gives a fraction of time spent of 0.1175.6.1.9. Inhalation Rate: NUREG/CR-6697 (ref 3.4) in Appendix 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. Multipling by 365.25 days/year gives a soil ingestion rate of 18.26g/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.

Multipling 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 listed in Table 2 below.Table 2 Miscellaneous Consumption Rates Parameter Value (NUREG//CR-5512 Vol. 3, Table 6.87)Fruit, veg & grain consumption 112 kg/yr Leafy vegetable consumption 21.4 kg/yr Milk consumption 233 L/yr Meat & poultry consumption 65.1 kg/d Fish consumption 20.6 kg/yr Page 14 of 28 Bartlett Engineering Calculation Sensitivity Analysis for EF-l DCGLs for Soil Calculation No. ENG-002 Rev. I 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 l/per 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 1/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 10-1° 1/sec.6.1.15 Humidity in Air The reference, "Regional and Site-Specific Absolute Humidity Data for Use in Tritium Dose Calculations", Health Physics, Vol.39, pp. 318-320, 1980 (ref. 3.7) provides a table of absolute humidity for selected locations in the U.S. These values were calculated from data from the National Oceanic and Atmospheric Administration, 1977, Climatological Data, Annual Summary, volume 28, U.S. Dept. of Commerce.

The value of 4.6 g/m 3 (Detroit, Michigan) was chosen from Table 1 of this technical paper for the RESRAD humidity parameter.

6.1.16 Average Annual Wind Speed The wind speed and direction, joint frequency distributions from Ref 3.10 obtained from Detroit Edison 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 the five year period from 2003 to 2007 are shown in Table 3. An average wind speed was calculated by summing 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 assigned to this parameter.

Sensitivity Analysis for EF-1 DCGLs for Soil ENG-002 Revision 1 6.1.17 Precipitation Table 4 provides monthly mean precipitation totals for Detroit, Michigan.

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.

Table 4 -Precipitation Rate Detroit,MI Monthly Mean Precipitation Totals (inches of water)Period:1971-2000 Month Precipitation (inches)Jan 1.91 Feb 1.88 Mar 2.52 April 3.05 May 3.05 Jun 3.55 Jul 3.16 Aug 3.1 Sept 3.27 Oct 2.23 Nov 2.66 Dec 2.51 Year Total 32.89 Converting to meters/year:

32.89 inches/year divided by 39.37inches/meter

= 0.84 meters/year.

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 Pr IRr Cr= the Evapotransporation Rate (m/y)= the Precipitation Rate (m/y)= the Irrigation Rate (m/y) and= the Runoff Coefficient.

Page 17 of 28 Bartlett Engineering Calculation Calculation No. ENG-002 Sensitivity Analysis for EF-1 DCGLs for Soil Rev. 1 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. ANL/EIS-8 (Ref 3.1) Figure 12.1 provides a map of the United States with the regional Average Annaul Potential Evapotranspiration Rate in inches per year. The midpoint of the average anuual evapotranspiration rate for the region around Newport, Michigan is 30 inches/year.

Converting to m/yr by multipling by2.54 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. 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 C 1 , C 2 and c 3 for various environments:

Cr, 1C- C2 -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.Cr = 1 -0.3 -0.4 -0.1 = 0.2 4. NUREG/CR-6697, Attachment C, Section 4.3-Evapotranspiration Coefficient, Ce, defines this parameter 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. The NUREG/CRrecommends the use of a uniform distribution with minimum and maximum values of 0.5 and 0.75, respectively and with 0.625 as median 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 5 below.Page 18 of 28 Bartlett Engineering Calculation Sensitivity Analysis for EF-1 DCGLs for Soil Calculation No. ENG-002 Rev. 1 Table 5 -Irrigation Rate Variable min value max value Evapotranspiration Rate (mly) ETr 0.762 0.762 Precipitation Rate (m/y) Pr 0.84 0.84 Runoff Coefficient Cr 0.2 0.2 Evapotranspiration Coefficient Ce 0.5 0.75 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 s 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 NUREG/CR-6676 (ref. 3.15).6.1.19 Well Pumping Rate 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 Livestock (m 3/y) 76.7 76.7 76.7 Contaminatedfraction for Irrigation I 1 I f, = 1 (assumes irrigation of the entire area))Irrigation rate I, (m/y) 0.598 0.344 0.852 Irrigation water (m 3/y) f, x lr X 2000 1196 688 1704 Drinking Water (m 3/y)** 1.91 1.91 1.91 Total for Family of Four (m 3/y) 1649 1141 2157 Page 19 of 28 Bartlett Engineering Calculation Sensitivity Analysis for EF-1 DCGLs for Soil Calculation No. ENG-002 Rev. 1* EPA recommends (ref 3.18) a Household Water Use for a family of four persons of 272 gallons per day (272 gal/day

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 for the shallow monitoring wells. The groundwater elevations recorded in Table 1 and the associated average elevation are listed in Table 7.Table 7 -Groundwater Elevations in Shallow Monitoring Wells at EF-1 EF Shallow 9/22/05 2/7/06 6/6/06 12/11/06 Average MW EFT-IS 576.93 576.73 577.64 578.5 577.45 EFT-2S 578.46 575.57 578.34 576.75 577.28 EFT-4S 579.31 582.76 581.07 580.6 580.94 EFT-5S 580.19 581.69 571.44 580.79 578.53 EFT-6S 577.85 579.23 578.88 578.16 578.53 EFT-7S 579.4 578.11 578.02 578.74 578.57 EFT-8S 575.12 575.96 575.36 575.48 EFT-8S/D 575.83 574.25 573.92 573.25 574.31 EFT-9S 579.07 578.26 578.82 578.02 578.54 EFT-10S 570.49 575.29 574.78 574.06 573.66 Avg GW El. 577.3 The Golder Associates Report also had in Appendix B Borehole and Monitoring Well Construction Logs for the shallow monitoring wells above.

6.2 Results The probabilistic module of the RESRAD code was used to perform the analyses to identify stochastic parameters having the greatest influence on the resultant dose and the associated DCGLs.The code was run individually for the nuclides listed in Section 5 at a concentration of 1 pCi per gram. The basic radiation dose limit was set to 25 mrem/yr.The RESRAD Probabilistic Output Report provides regression and correlation coefficients for the average doses at the user defined evaluation times (Attachment 3). Table 9 identifies for each radionuclide the sensitive parameters in order of rank and the PRCC values. The Partial Rank Correlation Coefficient (PRCC) has been used to identify sensitive parameters.

NUREG/CR-6676 (ref. 3-15), provides a sensitivity threshold of 0.25. The guidance further recommends the use of the PRCC if strong correlations exist between input parameters exists. The threshold for sensitivity usedin this calculation was a PRCC value with an absolute value greater than 0.25.Page 21 of 28 Bartlett Engineering Calculation Sensitivity Analysis for EF-1 DCGLs for Soil Calculation No. ENG-002 Rev. 1 Table 9 Sensitivity Analysis Results Based on the Partial Rank Correlation Coefficient Radionuclide Sensitive Parameter Units PRCC (file name)H-3 Depth of roots m -0.93 (MCSUMMARH3.REP)

Therefore, because 2000 observations were used in the sensitivity analysis for each radionuclide, the 2 5 th and 7 5 th percentile values will be the same for each radionuclide.

7 CONCLUSION-\

Parameters used in the Resident Farmer scenario were identified as sensitive if the absolute value of the PRCC was greater than or equal to 0.25. These sensitive parameter that were idetified are listed for each nuclide in order of PRCC rank in Table 11. The 2 5 th and 7 5 th percentile values for these senstive values are listed in Table 10 above. These input values are recommended for use as inputs in the RESRAD runs to calculate DCGLs for soil at EFl.Page 26 of 28 Bartlett Engineering.

Soil Sampling for CRA CRA Project # 049643 Bartlett Services Inc.Location:

Enrico Fermi Unit I On 6/23/08 soil sampling was performed at seven (7) locations at Fermi 1 adjacent to the Protected Area in locations as shown on the attached map. The samples were dug until a consistent soil texture was achieved.

In areas where grass was present the average sod thickness was approximately 5-10 centimeters thick. The layer of soils below the sod was a sandy loam type material with some areas containing more sand than others. The next layer was a thick clay soil with small rocks present (shown in the attached photo). This layer extended down to past 51 centimeters.

A considerable amount of moisture was present in some samples (see photo) most probably due to the amount of moisture received lately and the high water table. The following is a description of the soil sampling sites: 1. Sod depth of -10 cm. followed by dark colored sandy loam a depth of 15 cm. The next 24 cm. consisted of thick light brown clay with small rocks.2. Sod depth of 5-7.5 cm. followed by dark sandy loam to a depth of 15 cm.The next layer consisted of light brown sand to a depth of 24 cm. The next layer was a thick light brown clay with small rocks extending to a depth of 61 cm.3. Sod depth of 5-7.5 cm. followed by dark sandy loam to a depth of 20 cm.The next layer was uniform to a depth of 51 cm. consisting of light brown thick clay with small rocks.4. 2.5-12.5 depth of tar/asphalt with a layer of stone to a depth of 28 cm.From 28 cm. to a depth of 38 cm. wet, thick clay with small rocks.5. Stone and light brown clay mixture to a depth of 30 cm. then turning into a thick light brown clay with small rocks to a depth of 56 cm.6. Sod depth of 5-7.5 cm. followed by a layer of dark loam to a depth of 15 cm. The next layer was composed of gravel to a depth of 35.5 cm. The next layer was a mixture of dark sand and gravel extending past 61 cm.7. A layer of loose gravel covered the sample point to a depth of 10 cm.From there on the consistency was a dark sand/loam mixture with gravel extending past 66 cm.
