[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 W) BARTLETT 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-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:

0 Direct external radiation exposure pathway;* Inhalation exposure pathway;* Ingestion exposure pathway:-plant foods grown in the soil material containing residual radioactivity, B A RT L E TT 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.

[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

• Fraction of Time Spent Indoors and Fraction of Time Spent Outdoor* Irrigation Rate and Well Pumping Rate* Inhalation Rate* Soil Ingestion Rate* Drinking Water Intake 5.2.7. 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.WYBARTLETT 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-1 37, 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-152, 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-1 37 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-1 37 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 751h percentile value was selected when the absolute value of the PRCC for a given parameter was >0.25 and PRCC had a positive value.
