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 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. The RESRAD software allow the user to evaluate radiation exposure through several pathways: direct external radiation, inhalation, ingestion of plants, meat, milk, aquatic foods, and drinking water, inadvertent ingestion of contaminated soil, and radon exposure.The code requires input for numerous parameters in order to calculate the dose via various exposure pathways. 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 consists of two primary phases: the selection of input parameter values and performing RESRAD runs. The first phase involves classifying and prioritizing the RESRAD input parameters. The selection process is based on guidance provided in NUREG/CR-6697 [ref. 3.4], NUREG/CR-6676 [ref. 3.6], and NUREG/CR-6692 [ref.3.7]. Figure 1 provides a flow diagram for the parameter selection process.Classification, prioritization, and treatment of input parameters: Parameters were classified as behavioral, metabolic, or physical parameters consistent to the classifications found in NUREG/CR-6697 [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.Following the classification process, parameters were assigned priority rankings. Priority 1 parameters are high priority; Priority 2 parameters are medium priority; and Priority 3 parameters are low priority. NUREG/CR-6697 [ref. 3.4] provides prioritization rankings for input parameters. Those rankings were adopted in this calculation. The priority of a given parameter is 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.LFBARTL ETT Page 3 Bartlett Engineering ENG-HB-001 RESRAD Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0 Input parameters were treated as either deterministic (a single value is assigned) or stochastic (a probability distribution is assigned). Treatment depended on parameter type, availability of site-specific data, and the relevance of the parameter in the dose calculations. I" Behavioral and metabolic parameters were treated as deterministic and the assigned values were from NUREG/CR05512, volume 3 [ref. 3.2], NUREG/CR-6697 [ref. 3.4], or the RESRAD User Manual [ref. 3.3]. Parameters for which site-specific data are available were treated as deterministic." Physical parameters for which site-specific data are unavailable were assigned values based on priority. Priority 1 and 2 physical parameters were treated stochastic and assigned probability distributions from NUREG/CR-6697 [ref. 3.4], or assigned a deterministic value from NUREG/CR-5512, volume 3 [ref. 3.2].Priority 3 physical parameters were treated as deterministic and were assigned values from NUREG/CR-5512, volume 3 [ref. 3.2], or the RESRAD User's Manual [ref. 3.3].Following the parameter selection process, RESRAD input files were developed based on the results of the parameter selection process and a parameter sensitivity analysis was performed for each radionuclide of concern. Input correlations were applied based on guidance in NUREG/CR-6676 [ref. 3.6]. 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);* Effective porosity and bulk density = -0.99 (unsaturated and saturated zones); and* Well Pumping rate and irrigation

= 0.96.The RESRAD Probabilistic Output Report provides regression and correlation coefficients for the average doses at the user defined evaluation times. The Partial Rank Correlation Coefficient (PRCC) has been used to identify sensitive parameters. NUREG/CR-6692 [ref. 3.7]and NUREG/CR-6697 [ref. 3.4] recommend the use of the PRCC for cases where a non-linear relationship and widely disparate scales exists between the input and output. The guidance further recommends the use of the PRCC if strong correlations exist between input parameters. The criterion for sensitivity used in this calculation was a PRCC value with an absolute value greater than 0.25. In addition, PRCC values greater than zero (positive value) or less than zero (negative value) identify whether sensitive parameters are positively or negatively correlated to dose, respectively. Therefore, 7 5 th percentile values were determined for sensitive parameters that had positive PRCC values and 25 1 percentile values were determined for sensitive parameters that had negative PRCC values. These 251h and 7 5 1h percentile values address the uncertainties associated with the input parameters and are proposed as reasonably conservative input for the DCGL calculation for the Humboldt Bay site.The 2 5 th and 7 5 th percentile values were obtained using the following method: 1. Open the RESRAD "*.buo" file generated during from the sensitivity run using the"View Interactive Output" button on the RESRAD navigator.

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.

5.0 ASSUMPTIONS

AND INPUT 5.1 Assumptions

5.1.1. Radionuclides

of Concern (ROC). Twenty-two ROCs are identified for the Humboldt Bay [refs. 3.8 and 3.10]: Am-241, C-14, Cm243/244/245/246, Co-60, Cs-137, Eu-152, Eu-154, H-3, 1-129, Nb-94, Ni-59, Ni-63, Np-237, Pu-238/239/240/241, Sr-90, and Tc-99.5.1.2. 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 pathways used to estimate human radiation exposure resulting from residual radioactivity in the soil for this scenario includes the following:

Direct external radiation exposure pathway;" Inhalation exposure pathway;* Ingestion exposure pathway:-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, and-aquatic food from a pond containing residual radioactivity;
Inadvertent ingestion of contaminated soil 5.1.3. Conceptual Model: The conceptual hydrological model for this resident farmer scenario has three geological strata: 1) a contaminated zone, 2) an unsaturated zone, and 3) a saturated zone. The contaminated zone is assumed to be uncovered, equivalent in size to the largest contiguous Class 1 and 2 area at the Humboldt Bay site (see Figure 2), and variable in thickness.

The unsaturated zone is initially uncontaminated and also variable in thickness. The groundwater in the saturated zone is assumed initially uncontaminated.

5.2 Input

( BARTLETT Page 5 Bartlett Engineering ENG-HB-001 RESRAD Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0 5.2.1. Contaminated zone: The thickness of the contaminated zone was determined from characterization soil sample data provided in the HSA [ref. 3.10]. Plant-related radioactivity was detected in surface soil samples (6 inches or less in depth) and in a sub-surface sample collected at a depth of 11.5 feet. To account for the uncertainty of thickness of the contaminated zone, a uniform distribution was established using a minimum thickness equal to 6 inches and a maximum thickness equal to 11.5 feet.Well installation logs for 22 groundwater monitoring wells were reviewed for soil type descriptions to a depth of 11.5 ft (the maximum thickness of the contaminated zone)to determined a representative soil type for the contaminated zone. The soil type descriptions and the USCS codes recorded on the well logs were then compared to the soil categories listed Tables 3.1-1 and 3.2-1 in Attachment C to NUREG/CR-6697 [ref. 3.4]. Soil descriptions recorded in the "Lithologic Description" section of the logs served as the primary factor for selecting a RESRAD soil type category from the surface to a depth. When those descriptions did not match one of the soil types given in Attachment C to NUREG/CR-6697, the USCS code was used. Soil type selection focused on two soil characteristics: density and total porosity. These characteristics were weighted by depth and overall averages determined. The soil type for the contaminated zone was selected based on matching the overall average density and total porosity to the soil types given in Tables 3.1-1 and 3.2-1 in Attachment C to NUREG/CR-6697. Based on that approach, "clay loam" was selected from the soil type provided in NUREG/CR-6697 [ref. 3.4] as reasonably representative soil type for the contaminated zone. The "clay loam" soil classification was used as the basis for selecting input for other soil type-dependent parameters, such as hydraulic conductivity and the RESRAD soil-b parameter. Table 1A summarizes the soil type determination for the contaminated zone.5.2.2. Unsaturated zone: The thickness of the unsaturated zone was determined from 2009 groundwater monitoring data, which showed a minimum depth to groundwater equal to approximately 4.9 feet and a maximum depth equal to approximately 27 feet. To account for the uncertainty of thickness of the unsaturated zone, a uniform distribution was established using a minimum thickness equal to 0 inches and a maximum thickness equal to 26.5 feet.Using the same approach as that used to determine the soil type for the contaminated zone; "clay loam" was selected as reasonably representative soil type for the unsaturated zone. "Clay loam" was selected from the soil type provided in NUREG/CR-6697 [ref. 3.4] as reasonably representative soil type for the unsaturated zone. The "clay loam" soil classification was used as the basis for selecting input for other soil type-dependent parameters, such as effective porosity, hydraulic conductivity, and the RESRAD soil-b parameter. Table 1 B summarizes the soil type determination for the unsaturated zone.5.2.3. Saturated zone: Using the same approach as that used to determine the soil type for the contaminated and unsaturated zones; "silty clay loam" was selected as reasonably representative soil type for the saturated zone. The "silty clay loam" soil classification was used as the basis for selecting input for other soil type-dependent parameters, such as effective porosity, hydraulic conductivity, and the RESRAD soil-BARTLETT Page 6 Bartlett Engineering ENG-HB-001 RESRAD Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0 b parameter. Table 1C summarizes the soil type determination for the saturated zone.5.2.4. The value of the Lower Elk River Watershed [from the Humboldt Bay Power Plant FSAR], 2.52E+07 M 2 , was used as input for the RESRAD parameter"Watershed Area for Nearby Streams and Ponds." 5.2.5. Input values for annual precipitation and evapo-transpiration were obtained from the SAFSTOR Environmental Report [ref. 3.9]. NOAA recorded average wind speed data obtained from the National Climate Data Center website were used as the basis for wind speed.5.2.6. Table 2 summarizes the parameter name, type, priority, treatment, values/distribution and the reference source that provides the bases for each input parameter. Some parameter values required calculations. These calculations are documented in the next section.6.0 CALCULATIONS AND RESULTS 6.1 Figure 2, Area of the Contaminated Zone, was generated with AutoCAD. The size of the contaminated zone is based on the largest contiguous MARSSIM Class 1 and Class 2 at the Humboldt Bay site and includes the Protected Area and adjacent impacted areas. That area, 29,781 M 2 , was then rounded to the nearest thousand.For modeling purposes, the size of the Humboldt Bay contaminated zone is 30,000 2 m.6.2 The length parallel to the aquifer is defined 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 could be approximated by a circle with an area of 30,000 m 2 (the area of the contaminated zone). The diameter of the circle is suitable as input for the length parallel to the aquifer parameter and is calculated as follows: A=Trr 2 Where A is the area in m 2 and r is the radius in meters.30000 r = 97.7 m D = 2 x r = 2

97.7 D= 195m Therefore, the length of parallel is 195 m.6.3 Contaminated zone erosion rate: The slope of the contaminated zone was determined using elevations from site contour maps provided in the HSA [ref. 3.10]to determine the site grades in 3 directions within the contaminated zone (shown in Figure 3, Site Slope Directions).

This determination is summarized below: SBARTLETT Page 7 Bartlett Engineering ENG-HB-001 RESRAD Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0 Approximate Grade Distance Estimated Trial Difference between Pointsa Slope A 9.1 m 110m 8%B 6.1 m 151 m 4%C 6.1 m 85 m 7%average 6%a Locations of points shown in Figure 3.Data from NUREG/CR-6697, Attachment C, Section 3.8, was used to select the appropriate Erosion Rate that corresponds to the Humboldt Bay site slope of 6%.The data below was generated using NUREG/CR-6697's row-crop Erosion Rate of 6.0 E-4 for a 2 % slope. As recommended in this section of NUREG/CR-6697, the Erosion Rate of 6.0 E-4 for a 2% slope was assumed based on a farm-garden scenario where the dose contribution from the food ingestion pathway is expected to be significant. Erosion rates where then calculated for 5, 10 and 15 percent slopes (presented below) using their rate increase factors as specified in the Section 14.2 of Reference 3.1.Percent Erosion Rate Slope (m/y)2 6.OE-4 5 1.8E-3 10 4.2E-3 15 9.OE-3 Figure 5, Erosion Rate vs. Slope, was generated by plotting the above erosion rate/slope data. A value of 2.2E-03 m/y was selected from Figure 5 as input for the Erosion Rate parameter.

6.4 Field

capacity defines the relationship of field capacity (residual water content) to effective porosity [ref. 3.1]. 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 in Reference

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 For the Contaminated and Unsaturated Zones, the mean total porosity for clay loam soil is of 0.41 and the mean effective porosity is 0.315 [ref. 3.4]. Therefore the field capacity for these two zones is approximately: Field Capacity = 0.41 -0.315 = 0.095 For the Saturated Zone, the mean total porosity for silty clay loam soil is of 0.43 and the mean effective porosity is 0.342 [ref. 3.4]. Therefore the field capacity for this zone is approximately: (MBARTLETT Page 8 Bartlett Engineering ENG-HB-001 RESRAD Input Parameter Sensitivity Analysis-Humboldt Bay Rev. 0 Field Capacity = 0.43 -0.342 = 0.088 6.5 Hydraulic conductivity in the unsaturated zone: Attachment C to NUREG/CR-6697 discusses this parameter's use in the determination of the groundwater flow rate, which effects the rise time and the dilution of radionuclides in the well water. The method for calculating the hydraulic gradient is given in NUREG/CR-6697, Attachment C, Equation 3.6-1: Jx = (hi -h 2)/Ax Where J, is the hydraulic gradient, h, and h 2 represent the hydraulic heads or the water level elevations at location 1 and 2, and A, is the distance between the two locations. The water level elevations are referenced to mean sea level (msl). An average value for the Humboldt Bay site was calculated from three separate hydraulic gradient determinations as follows below. Figure 4, Well Locations, shows the well locations. 2009 Average Distance (ft)Well Type GW Elevation Between Wells Jx RCW-SFP-1 intermediate 5.65 RCW-SFP-2 intermediate 5.41 194 0.0012 1C-MW-08 shallow 5.23 1 E-MW-1 3 shallow 5.53 289 0.0028 RCW-CS-1 deep 5.23 RCW-CS-5 deep 6.03 157 0.0020 Average 0.0020 6.6 Runoff Coefficient: Table 10.1 of Reference

the equation below to calculate the Runoff Coefficient, Cr, for an agricultural environment and also provides values for the terms cl, c 2 , and c 3.Cr = 1 -C 1 -c 2-C3 cl = 0.2 for rolling land with an average slope between 4.6 to 6.1 m/mi. (assumed representative for the Humboldt Bay site)C2 = 0.2 for intermediate combinations of clay and loam C3 = 0.1 for cultivated lands (consistent with the resident farmer scenario). Cr = 1 -0.2 -0.2 -0.1 = 0.5 6.7 Fraction of Time Spent Indoors: Table 6.87 in NUREG/CR-5512 [ref. 3.2] provides values for the residential parameters. The indoors time is given as 240 days.Dividing by 365.25 d/y yields the fraction of time spent indoors equal to 0.6571.6.8 Fraction of Time Spent Outdoor: Table 6.87 in NUREG/CR-5512 [ref. 3.2] provides values for the residential parameters. The outdoor time value includes the period outdoors, 40.2 days, and time spent gardening, 2.92 days, which yields a sum of 42.92 days outdoor. Dividing by 365.25 d/y gives a fraction of time spent of 0.1175.(V B ARTLEETT Page 9 Bartlett Engineering ENG-HB-001 RESRAD Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0 6.9 Inhalation Rate: Appendix C to NUREG/CR-6697 [ref. 3.24] provides an estimated daily inhalation rate equal to 23 m 3/d for an adult male. This results an annual inhalation rate equal to approximately 8400 m 3/y.6.10 Soil Ingestion Rate: Table 6.87 in NUREG/CR-5512 [ref. 3.2] provides values for the residential parameters. The soil ingestion rate is given as 0.05 g/d; multiplying by 365.25 d/y gives a soil ingestion rate of 18.26 g/y.6.11 Drinking Water Intake: Table 6.87 in NUREG/CR-5512 [ref. 3.2] provides values for the residential parameters. The drinking water ingestion rate is given as 1.31 liters/d; multiplying by 365.25 d/y gives a drinking water ingestion rate of 478.5 liters/y.6.12 Irrigation Rate: Attachment C to NUREG/CR-6697 [ref. 3.4] discusses the Irrigation Rate in terms of the Evapotranspiration Coefficient, and provides the following equation for the Evapotranspiration Coefficient: Ce = (ETr)/(1-Cr)(Pr) + IRr Where: ETr = the Evapotransporation Rate (mly) = 0.61 [ref. 3.9]Pr = the Precipitation Rate (m/y) = 0.91 [ref. 3.9]IRr =the Irrigation Rate (m/y) and Cr = the Runoff Coefficient = 0.5 (from step 6.5).NUREG/CR-6697, Attachment C, Section 4.3 defines the Evapotranspiration Coefficient, Ce, 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/CR recommends the use of a uniform distribution with minimum and maximum values for Ce equal to 0.5 and 0.75, respectively, and with 0.625 as median.Rearranging this equation above, the Irrigation Rate can be expressed as: IRr = (ETr/Ce)-(1-Cr)(Pr) The input values for the variables in the equation above follow: Use of Min Use of Max Variable Ce Value Ce Value ETr (m/y) 0.61 0.61 Pr (m/y) 0.91 0.91 Cr 0.5 0.5 Ce 0.5 0.75 IRr (m/y) 0.77 0.36 The irrigation rate equation yields a minimum IRr value equal to 0.36 and a maximum IRr value equal to 0.77 m/y. A uniform distribution with minimum and maximum value equal to 0.36 and 0.77, respectively, and a median equal to 0.56 was assigned as input for this parameter.
