BHI Energy ENG-OCS-007 RESRAD-Onsite Probabilistic Analysis - Industrial Use Scenario Rev. 0 Page 1 of 28 1.0 PURPOSE This calculation identifies sensitive input parameters (i.e., those input parameters that produce a significant change in the calculated dose with changes in their value) in the modeling of the Industrial Use scenario using the RESRAD-Onsite code (version 7.2). Identification of sensitive input parameters is a necessary process to account for uncertainty in input values. The uncertainty associated with sensitive input parameters is addressed in subsequent derived concentration guideline levels (DCGL) calculations by determining and assigning reasonably conservative input values based on the results of RESRAD-Onsite probabilistic analyses. Thus, the results of this calculation support the development of DCGL values (based on the Industrial Use scenario) for soil in open land areas at the Oyster Creek Station (OCS) site.
2.0 APPLICABILITY This calculation addresses only the sensitivity analysis for input parameters for the Industrial Use scenario used to develop the DCGL values for soils at the OCS site.

The RESRAD code has undergone extensive review, benchmarking, verification, and validation [3.2]. The RESRAD-Onsite 7.2 Users Guide [3.3] was used as a reference for code use.
BHI Energy ENG-OCS-007 RESRAD-Onsite Probabilistic Analysis - Industrial Use Scenario Rev. 0 Page 2 of 28 The RESidual RADioactivity (RESRAD) model and computer code was developed at Argonne National Laboratory as a multifunctional tool to assist in developing radiological criteria for assessing the dose associated with residual radioactive material. The RESRAD-Onsite computer code is a pathway analysis model designed to evaluate the potential radiological dose associated with residual radioactive material.
RESRAD-Onsite input parameters allow site-specific modeling through entry of site data, such as contaminated zone area and depth, site soil hydrogeologic characteristics, and site soil strata information.
Also, the user can evaluate radiation exposure under different exposure scenarios by selecting scenario-specific exposure pathways.
The RESRAD-Onsite code includes probabilistic modules that permit the user to perform a sensitivity analysis to identify parameters that have the greatest impact on dose. The probabilistic modules allow the evaluation of dose as a function of parameter distributions.
The approach taken in this calculation consists of two primary phases: the selection of input parameter values and performing RESRAD-Onsite code executions.
Input parameters were treated as either deterministic (a single value is assigned) or stochastic (a parameter 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 were assigned values from NUREG/CR-5512 [3.5], NUREG/CR-7267, or the RESRAD User Manual. Physical parameters for which site-specific data are unavailable were assigned parameter distributions from NUREG/CR-7267 or assigned a deterministic value from either NUREG/CR-5512 or the RESRAD Users Manual.
The RESRAD-Onsite 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-7267 and NUREG/CR-6697 [3.6] recommend the use of the PRCC for cases where a non-linear relationship exists, such as in the case for the Industrial Use Scenario. 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.
The criterion for sensitivity used in this calculation was a PRCC value with an absolute value greater than 0.25. To address the uncertainties associated with the input parameters identified as sensitive, the 25th percentile value of the parameters distribution was selected for sensitive parameters that had a negative PRCC value, and the 75th percentile value of the parameters distribution was selected for sensitive parameters that had a positive PRCC value. The 75th percentile and 25th percentile values are recommended as reasonably conservative input values for calculations of DCGL values for open land areas at the OCS site. The approach of assigning 25th and 75th percentile values of a sensitive parameters distribution to account for uncertainty in DCGL values has been accepted in past decommissioning projects (e.g., Yankee Rowe, Zion, Connecticut Yankee, Humboldt Bay, Fort Calhoun Station, and SMUD) by the U.S. Nuclear Regulatory Commission (NRC) and State regulators.
5.0 INPUT and CALCULATIONS 5.1 Radionuclide-of-concern (ROC) 5.1.1 A site-specific suite of ROCs has been identified for the OCS site [3.7]. OCS ROCs are listed in Table 1.
NOTE: RESRAD-Onsite 7.2 automatically accounts for progeny radionuclides with input for several of the OCS ROCs. Progeny radionuclides are also listed in Table 1).

5.2 Exposure Scenario: The exposure scenario modelled in the sensitivity analyses is an Industrial Use Scenario. The average member of the critical group is a hypothetical full-time industrial site worker assigned outdoor tasks and who also catches and consumes fish from the intake/discharge canal during off-hours. The pathways used to estimate human radiation exposure resulting from residual radioactivity in the soil for this scenario are:
Direct external radiation exposure pathway Inhalation exposure pathway Ingestion exposure via aquatic food from the intake/discharge canal Inadvertent ingestion of contaminated soil 5.3 Time fractions: The industrial worker is assumed to spend 7h per day on outdoor tasks and 1h per day for indoor work breaks (i.e., 15 min morning break, 30 min lunch, and 15 min afternoon break). Under this assumption, the worker spends 35h/week performing outdoor tasks and 5h/week indoors on work breaks. Over a 50-week occupational year (i.e., 50 weeks), the worker spends (35h/week
- 50weeks =) 1750h outdoors at the industrial site and (5h/week
- 50weeks =) 250 h indoors at the site. A calendar year has (24h/d
- 365.25d
=) 8766h.
Fraction of calendar year off-site = (8766h - 2000h)/8766h = 0.77 (no exposure to radioactive material at the site during this time)
Fraction of calendar year outdoors at the site = 1750h/8766h = 0.20 (receives site radiation exposure)
Fraction of calendar year indoors at the site = 250h/8766h = 0.03 (receives site radiation exposure) 5.4 The industrial worker also fishes in the canal during off-hours. The dietary fraction of contaminated aquatic food is evaluated using a distribution from NUREG/CR-7267.
5.5 Contaminated zone (CZ): The OCS yard area within the perimeter fence, 124,400 m2 (based on CAD drawing of OCS PA) is used as input for the area of the CZ.
BHI Energy ENG-OCS-007 RESRAD-Onsite Probabilistic Analysis - Industrial Use Scenario Rev. 0 Page 4 of 28 5.5.1 Plant-related contamination has been reported at depth in OCS documents. Below are a few examples:
Soil samples collected between the MFOT and the RCA fence in late summer 1999 showed detectable radioactivity below the release criteria to a depth of 3 feet (HSA [3.8], section 7.2.1.5.4)
The radionuclides cobalt-60 and cesium-137 were identified down to a depth of almost 13 feet (HSA, section 7.2.1.2.7)
Highest levels of activity were found in the top meter of soil however activity was measured as far down as ~ 4 meters. (OC Contaminated Soil Volumes for Decommissioning Cost Estimates; RE: Old Radwaste Building - Waste Surge Tank Release)
Using 13 feet as the maximum depth for subsurface plant-related contamination, the minimum thickness of the CZ is set to the scenario default value, 6-inches (0.1524m), and the maximum thickness is set to 3.96 meters, which supports a uniform distribution with the minimum value = 0.1524 m, a maximum value = 3.96 m, and a mean value = 2.06 m.
5.5.2 Soil type: Sand was selected as the appropriate soil type for the CZ based on information provided in the 2017 Hydrogeologic Investigation Report [3.9].
5.6 The parameter length parallel to the aquifer flow is defined as is the maximum horizontal distance measured in the CZ, from its up-gradient edge to the down-gradient edge, along the direction of the groundwater flow in the underlying aquifer. The area of the CZ was approximated by a circle with an area of 124,400 m2 (the area of the OCS PA). The diameter of the circle with an area equal to 124,400 m2 was used as input for the length parallel to the aquifer parameter: 398 m.
5.7 Unsaturated zone (UZ):
5.7.1 The depth to ground water at the OCS site ranges from 5 ft to 20 ft [3.9]. Using that information and the minimum thickness of the CZ from step 5.5.1, the maximum thickness of the UZ is set to 19.5 ft (5.94m), which represents the depth from 6 inches to 20 ft (the upper end of the groundwater depth range), and the minimum thickness is set to 4.5 ft (1.37 m), which represents the depth from 6 inches to 5 ft (the lower end of the groundwater depth range). This allows a uniform distribution with a minimum value = 1.37 m, a maximum value = 5.94 m, and a mean = 3.65 m as RESRAD input for thickness of the UZ.
5.7.2 Sand was selected as the appropriate soil type for the UZ based on information provided in the 2017 Hydrogeologic Investigation Report.
5.8 Saturated zone (SZ):
5.8.1 Sand was selected as the appropriate soil type for the SZ based on information provided in the 2017 Hydrogeologic Investigation Report.
5.8.2 Hydraulic gradient in portions of the site range from 0.01 to 0.04 ft/ft [3.9]. This information allows a uniform distribution with a minimum value = 0.01, a maximum value = 0.04, and a mean value = 0.025 as RESRAD-Onsite input.
BHI Energy ENG-OCS-007 RESRAD-Onsite Probabilistic Analysis - Industrial Use Scenario Rev. 0 Page 5 of 28 5.9 The hydraulic conductivity for the site is reported as 24.62 ft/day [3.9]. Conversion to units required for RESRAD-Onsite input yields a hydraulic conductivity value = 2741 m/y.
5.10 The value assigned as input for effective porosity = 0.25 [3.9]
5.11 Input for the watershed area for nearby stream or pond parameter was determined by summing the areas of sub-watersheds within the Forked River/Oyster Creek Watershed (information taken from NJDEP BGIS, NJ GeoWeb site).
Sub-watersheds within the Forked River/Oyster Creek watershed:
Forked River NB (above old RR grade) 5,520.85 acres Forked River NB (below old RR grade) 4,629.91 acres Forked River (below NB incl Mid/South Br) 6,459.25 acres Oyster Creek (above Rt 532) 4,784.77 acres Oyster Creek (below Rt 532) 3,542.30 acres Total area:
24,937.1 acres = 1.01E+08 m2 5.12 The ground surface of the OCS site is described as relatively level [3.9]. Based on that description, an erosion rate equal to 6.0x10-4 m/y was selected for the OCS site as suitable for the Industrial Use scenario. The erosion rate for a relatively level site would not be expected to exceed 6.0x10-4 m/y.
5.13 Input value for annual precipitation was derived from information for the period from 2015 through 2020 (data from Annual Report on the Meteorological Program at Oyster Creek Generating Station for 2015 - 2020).
year Total Precipitation in/y m/y 2015 4.62E+01 1.17E+00 2016 2.79E+01 7.09E-01 2017 4.41E+01 1.12E+00 2018 7.63E+01 1.94E+00 2019 7.27E+01 1.85E+00 2020 6.33E+01 1.61E+00 Average 5.51E+01 1.40E+00 5.14 Figure 1 in Regional and Site-Specific Absolute Humidity Data for Use in Tritium Dose Calculations [3.10] provides mean absolute humidity by geographical regions within the U.S. The figure shows that the OCS site falls inside the area where the mean absolute humidity value is 6.6 g/m3. That value was selected for the RESRAD humidity parameter.
5.15 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 NUREG/CR-7267 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 CZ, UZ, and SZ, the mean total porosity for sand is 0.43 [3.4] and the effective porosity is 0.25 [3.9]. Therefore, the field capacity for these zones is approximately:
BHI Energy ENG-OCS-007 RESRAD-Onsite Probabilistic Analysis - Industrial Use Scenario Rev. 0 Page 6 of 28 Field Capacity = 0.43 - 0.25 = 0.18 5.16 Runoff Coefficient (Cr) was calculated based on information in Table 10.1 of 1993 Data Collection Handbook [3.11], which provides the equation for calculating Cr, and defines and provides values for the equation terms c1, c2, and c3. For the OCS site, Cr = 0.2.
5.17 Inhalation Rate: The distribution from NUREG/CR-7267 was selected as input for daily inhalation rate.
5.18 Soil Ingestion Rate: The distribution from NUREG/CR-7267 was selected as input for soil ingestion.
5.19 Wind speed for OGS is 7 mph (= 3.13 m/s) based on data from 7/2012 - 4/2018 (https://www.windfinder.com/windstatistics/oyster_creek_barnegat_bay) 5.20 Table 2 summarizes the input values/distribution and the reference source for each input parameter.
6.0 RESULTS 6.1 RESRAD-Onsite 7.2 was executed for each ROC using the input values provided in Table
- 2. An absolute PRCC value 0.25 was used as the criterion for identifying sensitive input parameters.
6.2 Table 3 summarizes the sensitive parameters for each ROC. Selected pages from the RESRAD-Onsite 7.2 Uncertainty Reports from each code execution are provided in Appendix A. RESRAD-Onsite parameters identified as sensitive are highlighted in yellow.
6.3 Table 4 summarizes the 25th and 75th percentile values for each identified sensitive input parameter for each ROC.
Note: For the sensitive parameters, the 75th percentile value of the distribution was selected when the absolute value of the PRCC was 0.25 and the PRCC had a positive value. The 25th percentile value was selected when the absolute value of the PRCC value was 0.25 but had a negative value.
7.0 CONCLUSION
S 7.1 Sensitive input parameters varied among the ROCs and included parameters such as Inhalation rate Mass loading for inhalation Soil ingestion Thickness of CZ Kd in the CZ Kd in the UZ Kd in the SZ External shielding factor Evapotranspiration coefficient Bioaccumulation for fish Contaminated fraction of aquatic food 7.2 The 25th and 75th percentile values for sensitive input parameters (presented in Table 4) provide reasonably conservative input for DCGL development.
