Humboldt Bay Power Plant License Termination Plan Chapter 6 Compliance with the Radiological Criteria for License Termination Revision 01 July 2014 Appendix A Basis for Site-Specific Parameter Values; Building Surfaces A-i Humboldt Bay Power Plant License Termination Plan Revision 01 Chapter 6 Compliance with the Radiological Criteria July 2014 for License Termination Site-specific information was used when available as the basis for the RESRAD-BUILD input parameter discussed below. NUREG/CR-6755, which documents the calculations of site-specific parameter values, provides the information presented below.1. Room Dimensions.

The model room was selected as a representative room for the Humboldt Bay site buildings and was used as the modeling basis for the building surfaces DCGLs. Table A-i shows the dimensions, unit conversion, and the area associated with each source (i.e., floor, walls, and ceiling) for the modeled room.Table A-i: Representative Room for Humboldt Bay Site Recorded Source Dimension No. Description (ft)a mb in2 1 floor N/A 47.77 2 north wall 27.8 8.47 21.09 3 east wall 18.5 5.64 14.04 4 south wall 27.8 8.47 21.09 5 west wall 18.5 5.64 14.04 wall height 8.17 2.49 total source area: 118.03 a Recorded length and width dimensions for representative room.b Feet to meter conversion factor: ift = 0.3048m.The wall length and height dimensions defined the room model and the location of the receptor.2. Source Configuration.

NUREG/CR-6755, Section 4.0, describes three principal assumptions inherent in the building scenario:

a fixed room area, uniforln surface contamination, and the receptor location at the center of the floor at a height of 1 meter. The room dimensions in Table A-I were used as the configuration bases for the source and the receptor locations.

The RESRAD-BUILD input parameters for receptor location and the centers of sources are provided in Table A-2.Table A-2: Location of Center of Sources and Receptor Source Source Location of Center of Source (m)No. Description X-axis Y-axis Z-axis 1 floor 4.24 2.82 0.00 2 north wall 4.24 0.00 1.25 3 east wall 0.00 2.82 1.25 4 south wall 4.24 5.64 1.25 5 west wall 8.47 2.82 1.25 6 ceiling 4.24 2.82 2.49 A-2 Humboldt Bay Power Plant License Termination Plan Revision 01 Chapter 6 Compliance with the Radiological Criteria July 2014 for License Termination

3. Direct Ingestion Rate.The RESRAD-BUILD source-specific input parameter, Direct Ingestion Rate, is the direct ingestion rate of the source by any receptor in the room. Direct ingestion represents the fraction of the source ingested per hour. NUREG/CR-5512, Volume 3, defines the average ingestion rate of 1.1E-4 m 2/h as representative for the average individual in an industrial setting. The Direct Ingestion Rate for use in the Building Occupancy Scenario was calculated based on the total room surface area (i.e., source area). The surface area is equal to the sun of the surface area of four walls, plus the surface areas of the floor and ceiling (118.03 m-2 , as shown in Table A-i).Direct Ingestion Rate = Average Ingestion Rate/Source Area= (1.1E-04 M2/1)/(1 18.03 M 2)= 9._2E-7 h'A-3 Humboldt Bay Power Plant License Termination Plan Chapter 6 Compliance with the Radiological Criteria for License Termination Revision 01 July 2014 Appendix B Input Parameter Values for Sensitivity Analysis:

The "non-sensitive" attribute of deposition velocity for these ROCs provided confidence that the uncertainty associated with the actual deposition velocity would not have a significant impact on dose or resulting DCGL values. Nevertheless, RESRAD-Build code executions were repeated using the 50th percentile value as input for the deposition velocity.

The results from the repeated RESRAD-Build executions confirm insignificant differences (i.e., less than 10 percent) in dose results based on use of the 25th percentile and 50th percentile values as input for deposition velocity.

Moreover, as shown in Table D-1 below, the inadvertent use of the 25h percentile value in the calculations of DCGLs actually resulted in slightly more conservative DCGL values in some cases.RAI 33 Table D- 1.

Reference 11, which documents the calculations of site-specific parameter values, provides the information presented below.1. Area of the Contaminated Zone Figure F-i, 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, 2 29,781 m2, was then rounded to the nearest thousand.

For modeling purposes, the size of the Humboldt Bay contaminated zone is 30,000 in 2.Figure F-i: Area of Contaminated Zone 2. Length Parallel to Aquifer Flow The length parallel to the aquifer is defined as is the maximum horizontal distance measured in the F-2 Humboldt Bay Power Plant License Termination Plan Revision 01 Chapter 6 Compliance with the Radiological Criteria July 2014 for License Termination 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= 7Er-Where A is the area in m 2 and r is the radius in meters.30000 H r 97.7 m D=2xr=2

97.7 D= 195m Therefore, the length of parallel is 195 m.3. Contaminated Zone Erosion Rate The slope of the contaminated zone was determined using elevations from site contour maps provided in the HSA (Reference

10) to determine the site grades in three directions within the contaminated zone. This determination is summarized below: Approximate Grade Distance Trial Difference between Pointsa Estimated Slope A 9.1 m lOrm 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 in Reference 11.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%.4. Soil Type Contaminated Zone: The thickness of the contaminated zone was determined from characterization soil sample data provided in the HSA (Reference 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 to determined a representative soil type for the contaminnated 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.

Soil descriptions F-3 Humboldt Bay Power Plant License Termination Plan Revision 01 Chapter 6 Compliance with the Radiological Criteria July 2014 for License Termination 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 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.

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 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.

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-b parameter.

5. Field Capacity: Field capacity 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 in Data Collection Handbook to Support Modeling the Impacts of Radioactive Material in Soil (ANL/EAIS-8, U.S.Department of Energy -Argonne National Laboratory, April 1993) 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. Therefore the field capacity for these two zones is approximately 0.095 For the Saturated Zone, the mean total porosity for silty clay loam soil is of 0.43 and the mean F-4 Humboldt Bay Power Plant License Termination Plan Revision 01 Chapter 6 Compliance with the Radiological Criteria July 2014 for License Termination effective porosity is 0.342. Therefore the field capacity for this zone is approximately 0.088.6. Irrigation Rate (Evapotranspiration and Runoff Coefficients)

Attachment C to NUREG/CR-6697 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 (m/y) = 0.61 (Humboldt Bay SAFSTOR Environmental Report, July 1984)Pr = the Precipitation Rate (m/y) = 0.91 (Humboldt Bay SAFSTOR Envirolnental Report, July 1984)IRr = the Irrigation Rate (mly) and Cr = the Runoff Coefficient.

The Data Collection Handbook to Support Modeling the Impacts of Radioactive Material in Soil (ANL/EAIS-8, U.S. Department of Energy -Argonne National Laboratory, April 1993) provides the equation below to calculate the Runoff Coefficient, Cr, for an agricultural environment and also provides values for the terms c 1 , 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 c 3 = 0.1 for cultivated lands (consistent with the resident farmer scenario).

Cr = 1 -0.2 -0.2 -0.1 = 0.5 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 thifs 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: Variable ETr (m/y)Pr (m/y)Cr Ce IRr (m/y)Use of Min Ce Value 0.61 0.91 0.5 0.5 0.77 Use of Max Ce Value 0.61 0:91 0.5 0.75 0.36 F-5 Humboldt Bay Power Plant License Termination Plan Revision 01 Chapter 6 Compliance with the Radiological Criteria July 2014 for License Termination The irrigation rate equation yields a minimum IRr value equal to 0.36 and a maxinmm 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.

7. Well Pumping Rate Well Pumping Rate: Attachment C to NUREG/CR-6697 states that "A site-specific input distribution for well pumping rate can be determined as the sum of individual water needs." The household use component as determined from the domestic use data is sununarized below.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 Contaminated fraction for Irrigation 1 1 1 fp = 1 (assumes irrigation of the entire area))Irrigation rate I, (m/y) 0.56 0.36 0.76 Irrigation water (m 3/y) fp x lr X 2000 1120 720 1520 Drinking Water (m 3/y) 2.04 2.04 2.04 Total for Family of Four (m 3/y) 1573 1173 1973* Household Use: Domestic Water Use for family of four, 376 m 3/y, minus the drinking water component, 1.91 m 3/y, or approximately 374 m 3/y.Domestic water use based on 272 gallons per day per family and drinking water based on use of 511 L/y per individual.

The same scenario is assumed for the AF calculations.

Areas of difference in input values are explained in the following discussion.

1. Contaminated Fractions

-Food Pathways As the size of the contaminated area (A) varies, the fraction of the total food consumed by the receptor grown in the contaminated area will also vary. The fraction of the food supply grown in the contaminated is referred to as a "contaminated fraction." Accordingly, with the decrease in the size of the contaminated area, a decrease in the values for the contaminated fraction of plant food ingested (FPLANT), the contaminated fraction of meat ingested (FMEAT), and contaminated fraction of milk ingested (FMILK) will also result.Adjustments to FPLANT were made based on information in the RESRAD User's Manual[Reference 10]. The following shows how the RESRAD code determines the contamination fraction (FA 3) for plants: FA 3 = A/2,000 when 0 < A < 1,000 m 2 FA 3 = 0.5 when A > 1,000 m-2 The above equations from the RESRAD User's Manual were adjusted to vary the input values for FPLANT, FMEAT, and FMILK in order to remain consistent with the approach used for the soil DCGLs (Ref. 3.1). The soil DCGLs were developed using a value of 1.0 for each of the contamination fractions, which incorporated the assumption that 100% of plant food, meat, and milk is obtained from an area equal to 30,000 m 2 (the size of the contaminated zone at the Humboldt Bay site). As applied to plants, use of a FA value equal to 1.0 in the calculation of the soil DCGLs effectively multiplied Equation D.5 by a factor of 2 to yield a FA value of 1.0 for areas equal to or greater than 1,000 n2 Input values for FPLANT used in this calculation are determined as follows: FPLANT = A/1,000 when A< 1,000 m-2 FPLANT = 1.0 when A > 1,000 m 2 In addition, the following information from the RESRAD User Manual (Ref. 3.5) shows how the RESRAD code determines the contaminated fractions for meat (FA 4) and milk (FA 5): FA4&5 = A/20,000 when 0 < A < 20,000 mn 2 FA4&5 = 1.0 when A > 20,000 mi2 The above relationships were used to vary input values for FMEAT and FMILK in order to remain consistent with the approach used for the soil DCGLs [Reference 13]. Table M-1 shows the values for FPLANT, FMEAT, and FMILK as a function of the area of the contaminated zone.2. Size of the Contaminated Zone Another RESRAD input parameter that is influenced by changes in the size of the contaminated zone is the length parallel to aquifer flow (LCZPAQ).

As the area of the contaminated zone M-2 Humboldt Bay Power Plant License Termination Plan Revision 01 Chapter 6 Compliance with the Radiological Criteria July 2014 for License Termination decreases, the value of LCZPAQ will also decrease.

Because the contaminated zone is assumed circular in shape, the value for LCZPAQ is equal to the diameter of the circle: Area of a Circle, A = E r-2 Rearranging and substituting for r = LCZPAQ 2 LCZPAQ (m) = 2 A Table M-1 also shows the values for LCZPAQ as a function of the area of the contaminated zone.Table M-1: Contaminated Fractions as a Function of the Size of the Contaminated Zone RESRAD Parameter Input Value Contaminated Zone (m 2) 30,0000a 2,000 1,000 500 100 LCZPAQ (m) 195a 50 36 25 11 FPLANT 1.0a 1.0 1.0 0.5 0.10 FMEAT 1.0a 0.1 0.05 0.025 0.005 FMILK 1.0a 0.1 0.05 0.025 0.005 Contaminated Zone (m7) 50 10 5 1 LCZPAQ (m) 8.0 3.6 2.5 1.1 FPLANT 0.05 0.01 0.005 0.001 FMEAT 0.0025 0.0005 0.00025 0.00005 FMILK 0.0025 0.0005 0.00025 0.00005 1 a Parameter value for DCGL modeling.M-3 Humboldt Bay Power Plant License Termination Plan Chapter 6 Compliance with the Radiological Criteria for License Termination Revision 01 July 2014 Appendix N Soil Area Factors N-i Humboldt Bay Power Plant License Termination Plan Chapter 6 Compliance with the Radiological Criteria for License Termination Revision 01 July 2014 Area Factor for Area Contaminated Zone (M 2): ROC 2000 1000 500 100 50 10 5 1 Am-241 C-14 Cm-243 Cm-244 Cm-245 Cm-246 Co-60 Cs-137 Eu-152 Eu-154 H-3 1-129 Nb-94 Ni-59 Ni-63 Np-237 Pu-238 Pu-239 Pu-240 Pu-241 Sr-90 Tc-99 1.OE+00 I.OE+00 1.OE+00 1.OE+00 I.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 I.OE+00 1.OE+00 1.OE+00 I.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.5E+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.OE+00 1.1E+00 1.1E+00 1.OE+00 1.2E+00 1.2E+00 1.OE+00 1.OE+00 1.OE+00 I.OE+00 I.OE+00 1.OE+00 1.OE+00 2.OE+00 4.OE+00 1.6E+00 2.OE+00 1.9E+00 2.OE+00 1.1E+00 1.3E+00 1.OE+00 1.OE+00 2.1E+00 2.2E+00 1.OE+00 2.3E+00 2.3E+00 2.OE+00 2.OE+00 2.OE+00 2.OE+00 2.OE+00 2.OE+00 2.OE+00 8.7E+00 4.2E+01 3.4E+00 9.7E+00 6.2E+00 9.7E+00 1.3E+00 1.7E+00 1.1E+00 1.2E+00 1.OE+01 1.1E+01 1.2E+00 1.2E+01 1.2E+0 1 9.OE+00 9.7E+00 9.7E+00 9.7E+00 8.8E+00 1.OE+01 1.OE+01 1.6E+01 1.1E+02 4.3E+00 1.9E+01 9.2E+00 1.9E+01 1.4E+00 1.9E+00 1.3E+00 1.3E+00 2.1E+01 2.2E+01 1.3E+00 2.3E+01 2.3E+0 1 1.6E+01 1.9E+01 1.9E+01 1.9E+01 1.6E+01 2.OE+01 2.OE+01 4.9E+0 1 1.OE+03 7.3E+00 7.6E+0 1 1.9E+01 7.6E+01 2.2E+00 3.OE+00 2.OE+00 2.OE+00 1.OE+02 9.9E+01 2.OE+00 1.2E+02 1.2E+02 5.6E+01 7.6E+01 7.6E+01 7.6E+0 1 4.9E+01 9.9E+01 1.OE+02 7.7E+0 1 2.5E+03 1.1E+01 1.2E+02 3.OE+01 1.3E+02 3.3E+00 4.5E+00 3.OE+00 3.OE+00 2.OE+02 1.9E+02 3.OE+00 2.3E+02 2.3E+02 9.8E+01 1.3E+02 1.3E+02 1.3E+02 7.8E+01 2.OE+02 2.OE+02 1.9E+02 1.8E+04 3.2E+01 2.8E+02 8.1E+01 2.8E+02 1.OE+01 1.4E+01 9.1E+00 9.2E+00 9.3E+02 8.3E+02 9.OE+00 1.2E+03 1.2E+03 3.5E+02 2.8E+02 2.9E+02 2.9E+02 1.9E+02 9.6E+02 I.OE+03.1.N-2 2 BARTLETT ENGINEERING CALCULATION Calculation Number: ENG-HB-001 Revision Number: 0 Calculation Title: RESRAD Input Parameter Sensitivitv Analysis -Humboldt Bav Preparer: Date 12/14 t Date / 2 Date c2 -olo--o Approval:-'iV re-sident Engineering/Corporate Project Manager Bartlett.60 Industrial Park Road Plymouth, MA 02360 Bartlett Engineering ENG-HB-001 RESRAD Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0 1.0 PURPOSE The purpose of this calculation is to determine which of the input parameters for the resident farmer scenario have a significant impact on the calculated dose (i.e., those parameters whose values greatly influence the calculated dose; aka, "sensitive" input parameters).

[ref. 3.5]. 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 vplidation.

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.(ABARTLETT 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.

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 2 5 th percentile values were determined for sensitive parameters that had negative PRCC values. These 2 5 th and 7 5 th 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 75t' 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.

2. Click the "Results" tab in the interactive output window.3. Click on the "Graphics" tab.CIBARTLETT Page 4 Bartlett Engineering ENG-HB-001 RESRAD Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0 4. Select "input vector" by scrolling through the choices under the "Primary Object" prompt.5. Select the desired parameter by scrolling through the choices under the "Input Parameter" prompt.6. Right click on the cumulative probability graph and select "Edit Chart Data." 7. Scroll down until the desired fraction (i.e., 0.25 or 0.75) is visible in column C2.The corresponding value in column C1 is the percentile value.The sensitivity analyses were run using 2000 observations and 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.

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-1 52, Eu-1 54, 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.

(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 1 A 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 =-n- r2 Where A is the area in M2 and r is the radius in meters.r =r = 97.7 m D = 2 x r = 2

97.7 D = 195 m 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: BARTLETT Page 7 Bartlett Engineering ENG-HB-001 RESRAD Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0 Approximate Grade Distance Estimated Trial Difference between Points' Slope A 9.1 m 110 m 8%B 6.1 m 151 m 4%C 6.1 m 85 m 7%average 6%'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:

(&BARTLETT 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: J, = (hi -h 2)/Ax Where Jx 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.

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 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.W, BARTLETT 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 (m/y) = 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.

4.0 METHOD

OF CALCULATION The operability of the RESRAD-Build code version 3.5 was verified on each computer use for code executions in accordance with the Bartlett Engineering procedure ENG-AP-02, Verification of Software Operability

[ref. 3.1]. The RESRAD-Build user's manual [ref. 3.2] provided guidance for code operation.

%BARTLETT Page 2 Bartlett Engineering ENG-HB-002 RESRAD-Build Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0 The sensitivity analysis for the building scenario input parameters was performed using Version 3.5 of the RESRAD-Build computer code, which was developed by Argonne National Laboratory under the sponsorship of the U.S. Department of Energy and other federal agencies.

The code requires input for numerous parameters in order to calculate the dose via various exposure pathways to a hypothetical individual working in a laboratory room contaminated with radioactive material.

The probabilistic modules in RESRAD-Build permit the user to perform a sensitivity analysis to identify those parameters that have the greatest impact on dose. In addition, the probabilistic modules allow the evaluation of dose as a function of parameter distributions.

Verification of the RESRAD-Build code is documented in the RESRAD-Build user's manual [ref. 3.2] and testing for the probabilistic codes is discussed in NUREG/CR-6697

[ref. 3.4].The RESRAD-Build computer code is a pathway analysis model designed to evaluate the potential radiological dose incurred by an individual who works in a building contaminated with radioactive material.

The exposure scenario modeled in this calculation is the building occupancy scenario, which provides estimates of human radiation exposures to residual radioactivity on surfaces inside standing buildings and permits the determination of DCGLs for building surfaces.

The exposure pathways considered are:* direct external exposure from the source (i.e., radioactive material deposited on the floor, walls, and ceiling),* external exposure from deposited material,* external exposure due to air submersion,* exposure due to inhalation of airborne radioactive material, and* ingestion of radioactive material directly from the sources and material deposited on the surfaces.The approach taken in this calculation consists of two primary phases: the selection of input parameter values and performing RESRAD-Build runs. The first phase involves classifying and prioritizing the RESRAD-Build input parameters.

The selection process is based on guidance provided in NUREG/CR-6676

[ref 3.7], NUREG/CR-6697

[ref. 3.4], NUREG/CR-6692

[ref. 3.8], and NUREG/CR-6755

[ref. 3.5]. 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, Page 3 Bartlett Engineering ENG-HB-002 RESRAD-Build Input Parameter Sensitivity Analysis -Humboldt Bay Rev. 0" the parameter type, and" the availability of parameter-specific data.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." Behavioral and metabolic parameters were treated as deterministic and the assigned values were from NUREG/CR05512, volume 3 [ref. 3.3], NUREG/CR-6697 [ref. 3.4], NUREG/CR-6755

[ref. 3.5], or the RESRAD-Build User's Manual[ref. 3.2]. 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 NREG/CR-5512, volume 3[ref. 3.3], NUREG/CR-6697

[ref. 3.4], NUREG/CR-6755

[ref. 3.5], or assigned a deterministic value from NUREG/CR-5512, volume 3 [ref. 3.3], NUREG/CR-6697

[ref.3.4], or NUREG/CR-6755

[ref. 3.5]. Priority 1 and 2 physical parameters for which site-specific data are available were treated as deterministic.

Priority 3 physical parameters were treated as deterministic and were assigned values from NUREG/CR-5512, volume 3 [ref. 3.3], NUREG/CR-6697

[ref.3.4], NUREG/CR-6755

[ref. 3.5], or the RESRAD-Build User's Manual [ref 3.2].Following the parameter selection process, RESRAD-Build 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. 3.7].The RESRAD-Build 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 with the limit set at 0.1.NUREG/CR-6692

[ref. 3.8] 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 0.1. In addition, PRCC values that are 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 values were determined for sensitive parameters that had positive PRCC values and 2 5 th values were determined for sensitive parameters that had negative PRCC values. These 2 5 th and 7 5 th percentile values are proposed as reasonably conservative input for the DCGL calculation for building surfaces.The 2 5 th and 7 5 th percentile values were obtained using the following method: 1. Open the RESRAD-Build

2. Click the "Results" tab in the interactive output window.3. Click on the "Graphics" tab.4.

Select the desired parameter by scrolling through the choices under the "Input Parameter" prompt.6. Right click on the cumulative probability graph and select "Edit Chart Data." 7. Scroll down until the desired fraction (i.e., 0.25 or 0.75) is visible in column C2.The corresponding value in column C1 is the percentile value.5.0 ASSUMPTIONS AND INPUT 5.1 Assumptions Building Scenario description:

The RESRAD-Build code v3.5 was used to model (through use of input parameter values) the building occupancy scenario defined in NUREG/CR-5512, volume 1 [ref. 3.5]. Modeling of this scenario provides an estimate of human radiation exposure to residual radioactivity on surfaces inside standing buildings and permits the determination of DCGLs for building surfaces.

Five exposure pathways are assumed active: (i) direct external exposure from the source (i.e., radioactive material deposited on the floor, walls, and ceiling), (ii) external exposure from deposited material, (iii) external exposure due to air submersion, (iv) exposure due to inhalation of airborne radioactive material, and (v) ingestion of radioactive material directly from the sources and material deposited on the surfaces.The following radionuclides are assumed the only radionuclides-of-concern (ROCs) for the Humboldt Bay site: 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.The hypothetical worker is assumed to perform activities inside an office room for a full occupational year.Figure 2 provides an illustration of the General Office in the Administration Building, which was selected as representative room for the Humboldt Bay site. The General Office was selected because it represents the type of room that would be occupied by full-time employees after license termination.

For modeling purposes, a rectangular room (18.5 ft by 27.8 ft) with 8.2 ft walls was assumed. This modeled room included 6 area sources (i.e. floor, 4 walls, and ceiling).5.2 Input Table 1 summarizes the classification, prioritization, values and their bases for all input parameters.

Room area* Room height* Receptor location* Location of center of source* Source length* Source area Statistical distributions from NUREG/CR-6755

[ref. 3.5] provided input for: " deposition velocity,* air exchange rate for room,* resuspension rate, and* time for source removal.An input correlation of 0.9 between the deposition velocity and the resuspension rate was applied based on guidance in NUREG/CR-6676

[ref. 3.7]. In addition, because the sources are assumed constructed of the same material and subject to the same environment, an input correlation of 0.9 was applied for the time for source removal between sources.6.0 CALCULATIONS AND RESULTS 6.1 Room dimensions:

dimensions of a representative room are 18.5ft by 27.8ft by 8.17ft (5.64m by 8.47m by 2.49m) shown in Figure 2. Table 2 shows the unit conversion for the room dimensions and the area associated with each source (i.e., floor and walls).6.2 Direct ingestion rate (h 1) is calculated from the indirect ingestion rate from NUREG/CR-6755

[ref. 3.5], 1.1 E-04 m 2/h, and the total source area (using the floor and wall areas), 118.03 M 2 , as follows: (1.1 E-04 m 2/h)/(118.036 M 2) = 9.32E-7 h 1 6.3 Using the dimensions for the designated north and east walls in Figure 2 (18.5 ft and 27.8 ft, respectively) and a wall height of 8.17 ft (Figure 2), the locations of the centers of the sources were determined as the mid-point on the X, Y, and Z-axes.Table 3 presents the locations for the center of the sources.6.4 RESRAD-Build v3.5 results: Table 1 summarizes the input used in each RESRAD-Build code execution.

Appendix A provides copies of selected pages from the RESRAD-Build uncertainty reports.6.4.1 Each of the radionuclides listed in section 5.1 was evaluated in separate code executions.

UBARTLETT Page 6 Bartlett Engineering RESRAD-Build Input Parameter Sensitivity Analysis -Humboldt Bay ENG-HB-002 Rev. 0 6.5 PRCC values were reviewed against the sensitivity criterion (i.e., I PRCCI >0.1).Deposition velocity, the resuspension rate, and the time for source removal were identified as sensitive input parameters for all ROCs. Table 4 summarizes the sensitive parameters by radionuclide.

6.6 The 2 5 th and 7 5 th percentile values for sensitive input parameters were obtained through use of the interactive output in the RESRAD-Build code. Table 5 presents these values.6.6.1 A comparison of the 2 5 th and 7 5 th percentiles values obtained from the RESRAD-Build code to the distributions given in NUREG/CR-6697

[ref.3.4] indicates that the 2 5 th and 7 5 th percentile values are reasonably conservative.

Table 5 includes this comparison.

[ref. 3.5]. 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 SBARTLETT Page 2 Bartlett Engineering ENG-HB-003 Humboldt Bay Soil DCGLs Rev. 0 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 allows 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.In the previous Bartlett Engineering Calculation ENG-HB-001 (ref. 3.1), the probabilistic modules in RESRAD Ver. 6.5 were used to perform a sensitivity analysis to identify parameters that have the greatest impact on dose. The results from these RESRAD Ver. 6.5 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. 6.5 Interactive Report was than used to identify the 25th or 75th percentile values for the sensitive parameters shown in Table 1.The values summarized in Table 2, which include reasonably conservative values for the identified sensitive RESRAD parameters, were used as input in separate executions of the RESRAD code for each of the radionuclides of concern (ROCs) at the Humboldt Bay site. The probabilistic module of RESRAD software was used to compute a "peak of the mean" (POM)dose. The POM dose for each ROC was used to determine the DCGL value that corresponded to the NRC dose criteria established in 10CFR20.1403 (i.e., 25 mrem/y). The DCGL value for each ROC was calculated as follows: DCGL(pCi/g)

= 25 mrem/y divided by POM dose (mrem/y per pCi/g).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-1 54, 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, Page 3 Bartlett Engineering ENG-HB-003 Humboldt Bay Soil DCGLs Rev. 0-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

The bases and derivations for input listed below have been documented in Reference 3.1 and are only summarized here. For additional details, refer to Reference 3.1.5.2.1. Contaminated zone: The thickness of the contaminated zone was determined from characterization soil sample data that showed plant-related radioactivity was detected in surface soil samples (6 inches or less in depth) to a sub-surface depth of approximately 12 feet. A site-specific uniform distribution was developed and used in the sensitivity analysis (Ref. 3.1). The thickness of the contaminated zone was identified as a sensitive RESRAD input parameter for most ROCs (Ref. 3.1).Therefore, to increase conservatism and to account for the uncertainty in the thickness of the contaminated zone, the 7 5 th percentile value from the site-specific distribution (provided in Table 1) is used as input for developing DCGLs."Clay loam" was selected from the soil type as a reasonably representative soil type for the contaminated zone (refer to ENG-HB-001

[ref. 3.1] for a detailed description of the approach).

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.

5.2.2. Unsaturated

zone: A uniform distribution was established based groundwater well data showing on a minimum thickness equal to 0 inches and a maximum thickness equal to 26.5 feet (details are provided in ENG-HB-001

[ref. 3.1])."Clay loam" was selected from the soil type 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.

5.2.3. Saturated

zone: "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-b parameter.BARTLETT Page 4 Bartlett Engineering ENG-HB-003 Humboldt Bay Soil DCGLs Rev. 0 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. Calculations for input values for the following RESRAD parameters are provided in ENG-HB-001

[ref. 3.1]: " Area of the Contaminated Zone and length parallel to the aquifer* Contaminated zone erosion rate* Field capacity for the contaminated, unsaturated, and saturated zones* Hydraulic conductivity in the unsaturated zone* Runoff Coefficient

Table 2 summarizes the parameter name, type, priority, treatment, values/distribution and the reference source that provides the bases for each input parameter.

6.0 RESULTS

6.1 RESRAD 6.5 was executed for each ROCs using the input values provided in Table 2. Table 3 summarizes the POM dose for each ROC. Selected pages from the RESRAD 6.5 Summary and Uncertainty Reports from each code execution are provided in Appendix A.6.2 The DCGL for each ROC was calculated from POM dose using the following relationship:

DCGL(pCi/g)

= 25 mrem/y divided by POM (mrem/y per pCi/g)6.3 Table 3 provides the DCGL corresponding to an annual dose equal to 25 mrem under the resident farmer scenario.6.4 For practical application, the DCGL values were rounded down to 2 significant digits. Table 4 presents the rounded DCGL values.CPBARTLETT Page 5 Bartlett Engineering Humboldt Bay Soil DCGLs ENG-HB-003 Rev. 0 Table 1: RESRAD-Generated Percentile Values for Sensitive Input Parameters (copy of Table 4 in Reference 3.1)RESRAD Percentile Valuea Sensitive Input Parameter Affected Nuclide 2 5 th 7 5 th Thickness of contaminated zone (m) Am-241, C-14, Cm-243/244/245/246, 2.67E+00 Co-60, Cs-137, H-3, 1-129, Ni-59, Ni-63, Np-237, Pu-238/239/240/241, Sr-90, Tc-99 Depth of roots (m) Am-241, C-14, Cm-243/244/245/246, 1.22E+00 Co-60, Cs-137, H-3, 1-129, Ni-59, Ni-63, Np-237, Pu-238/239/240/241, Sr-90, Tc-99 External shielding factor Cm-243, Co-60, Cs-1 37, Eu-1 52, Eu- 3.98E-01 154, Nb-94 Thickness of evasion layer (m) C-14 4.27E-01 Plant transfer factor Am-241 (the plant transfer factor was 1.83E-03 (pCi/g plant per pCi/g soil) also found sensitive for the Am-241 as a daughter product for Pu-241)Cm-243/244/245/246 1.83E-03 Co-60 1.46E-01 Cs-137 7.82E-02 1-129 3.67E-02 Ni-59/63 9.12E-02 Np-237 3.67E-02 Pu-238/239/240 1.83E-03 Sr-90 5.90E-01 Tc-99 9.16E+00 Meat transfer factor (pCi/kg per pCi/d) Co-60 5.86E-02 Cs-137 6.52E-02 1-129 5.23E-02 Milk transfer factor (pCi/I per pCi/d) Cs-137 1.39E-02 1-129 1.39E-02 Ni-59/63 3.21 E-02 Kd in contaminated zone (cm 3/g) Am-241 (as daughter product for Pu- 1.20E+04 241)Eu-1 52 7.22E+03 H-3 4.30E-02 Nb-94 3.56E+03 Tc-99 4.28E+00 a The 7 5 th percentile value was selected when the absolute value of the PRCC for a given parameter was >0.25 and PRCC had a positive value.
