RESRAD 6.21 Sensitivity Analysis for Resident Farmer Scenario-Soil Page: 3 A. PURPOSE:

The purpose of this calculation is to identify the stochastic parameters used in the RESRAD Resident Farmer Scenario that have the greatest influence on the peak of the mean dose. The identification of the sensitive parameters isaccomplished through the use of the probabilistic modules in the RESRAD version 6.21 computer code. A flow-charted process is used to identify parameters as behavioral, metabolic or physical.

Metabolic and behavioral parameters are assigned site-specific values or values from NUREG/CR -5512 Vol.

3,or NUREG/CR-6697. Physical parameters are assigned site-specific values or are treated stochastically and assigned a distribution from NUREG/CR-6697. The distribution statistics are used as the input to the probabilistic module of RESRAD. The Partial Rank Correlation Coefficient (PRCC) is used as the measure of the sensitivity of the dose to variations in the input parameter.

B.

SUMMARY

OF RESULTS:

A summary of results of the sensitivity analysis for the nuclides in Table 2 is presented below. Parameters were identified as sensitive if the absolute value of the PRCC was gre6ter than or equal to 0.25 and non-sensitive if the absolute value of the PRCC was less than 0.25. Parameters are listed in order of PRCC rank.

RESRAD 6.21 Sensitivity Analysis for Resident Farmer Scenario-Soil Page: 6 D. ASSUMPTIONS:

1. Radionuclide List The sensitivity analysis runs of the RESRAD Resident Farmer scenario were performed for the radionuclides listed in Table 2. This list of radionuclides was developed by consideration of historical site data, waste stream'analyses and source terms in NUREG guidance to encompass the radionuclides that may present a significant dose impact (Ref. 1).

2. Dose Model: The Resident Farmer Scenario of RESRAD 6.21 The dose model used to perform the sensitivity analyses and to calculate subsequent soil DCGLs is based upon the Resident Farmer Scenario defined in NUREG/CR-5512 Volumes 1,2 and 3 (Ref. 2). The dose model translates residual soil radioactivity into potential radiation dose and is defined by the scenario, exposure pathways and the critical group. The resident farmer scenario is a reasonably conservative bounding scenario, which generally overestimates (rather than underestimates) potential dose.

The residual radioactivity in this scenario is assumed to be contained in a soil layer on the property that can be used for residential and light farming activities. The residential farming family is postulated to live onsite, raise crops and livestock for consumption and drink water from a ground water source onsite. The dose from residual radionuclides in the soil is evaluated for the average member of the critical group as required by 10CFR Part 20, Subpart E and described in NUREG-1727, Appendix C (Ref. 3, Ref. 4). The critical group represents the group reasonably expected to receive the greatest exposure, given the' scenario, to residual radioactivity The potential exposure pathways that define the residential farmer scenario are:

1. Direct exposure to external radiation from radionuclides in the soil

2. Internal dose from inhalation of airborne radionuclides, and

3. Internal dose from ingestion'of radionuclides in

a. Crops grown on the property'and irrigated with water obtained onsite,

b. Meat and milk obtained from livestock fed f6dder and water produced onsite,

c. Drinking water from an onsite well,

d. Fish from an onsite pond and

e. Soil.

3. Conceptual Model underlying the dose model' The conceptual model used in the code was based on the site characteristics expected at the time of release of the site. The model is comprised of a contaminated zone underlain by an unsaturated zone underlain by a saturated zone. The contaminated zone is assumed to be at the ground surface with no

Subject:

RESRAD 6.21 Sensitivity Analysis for Resident Farmer Scenario-Soil Page: 7 cover material and the ground water is initially uncontaminated. The model as described is consistent with that described by Yu et al., 1993 (Ref. 5).

E. METHOD / BODY OF CALCULATION:

1. Parameter Selection Process The dose and conceptual models are quantified by a set of input parameters that are listed in Attachment 2, Table 1 under the following categories

• Soil Concentration

• Distribution Coefficients

• Calculation Time

• Contaminated Zone

• Cover and Hydrological Data

• Saturated Zone Hydrological Data

• Unsaturated Zone Hydrological Data

• Occupancy

• Ingestion, Dietary

• Ingestion, Non-dietary

• Storage Times

• Special Radionuclides (C-14)

• Dose Conversion Factors

• Transfer Factors Incorporated within RESRAD Version 6.21 are probabilistic.modules that allow the evaluation of dose as a function of parameter distributions. The code output provides a measure of the sensitivity of the dose to variations in parameter values as defined by the statistical parameters of an assigned probability distribution. To aid in selecting which.parameter sensitivities to evaluate, a process was followed in this calculation that was developed in accordance with guidance from NUREG/CR-6676, -6692, and -6697 (Ref. 6, Ref. 7, Ref. 8). A schematic flow diagram of the parameter selection process is provided in Figure

1. Each step of the selection process is discussed below.

Classification (Type):

The parameters were classified as behavioral, metabolic or physical consistent with NUREG/CR-6697.

-Behavioral parameters depend on the behavior of the receptor and the scenario definition. Metabolic parameters represent the metabolic characteristics of the receptor and are independent of the scenario definition. Physical parameters are the parameters that would not change if a different group of receptors were considered.

Prioritization The NUREG/CRi6697 approach to prioritizing parameters was applied in this calculation. The priority of a particular parameter is based upon:

1. The relevance of the parameter in dose calculations,

2. The variability of the dose as a result of changes in the parameter value,

.3. The parameter type and

4. The availability of parameter-specific data.

Priority I parameters are considered to be high priority; Priority 2 parameters are considered to be medium priority; and Priority 3 parameters are considered to be low priority.

Subject:

RESRAD 6.21 Sensitivity Analysis for Resident Farmer Scenario-Soil Page: 8 Treatment Input parameters are treated as either"deterministic -assigned a single value, or stochastic' -assigned a probability distribution. The treatment depends on parameter type, priority, availability'of site-specific data and the relevance of the parameter in dose calculations.

. Behavioral and metabolic parameters are treated as deterministic and are assigned values from NUREG/CR-5512, Volume 3, NUREG/CR-6697, or the RESRAD default library.

• Physical parameters for which site-specific data is available are treated as deterministic based on information in Attachment 1, YA-REPT-00-002-003 (Ref. 9) and YA-REPT-00-004-003 (Ref.

10).

. The remaining physical parameters, for which no site-specific data is available, are assigned

- values based on priority. Priority I and 2 parameters were treated as stochastic and are assigned a probability distribution from NUREG/CR-6697. The priority 3 physical parameters were treated as deterministic and are assigned values from NUREG/CR-5512, Volume 3, NUREG/CR-6697, or the RESRAD default library.

Parameter values and the basis for the assignment are summarized in Attachment 2, Table 1.

2. RESRAD Resident Farmer Sensitivity Analysis Runs The probabilistic module of the RESRAD code was used to perform the analyses to identify stochastic parameters having the greatest influence on the resultant dose and the associated DCGLs. The data in Attachment 2, Table I were used as inputs to the RESRAD code and, where appropriate, the probability distribution statistical parameters were entered into the probabilistic modules of the code. The code is run individually for the nuclides listed in Table 2 at a concentration of 1 pCi per gram. Prior to use, the operability of the RESRAD Version 6.21 code was verified in accordance with YNPS Procedures.

Sample Specifications The analyses were run using 2000 observations and I 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 was used to preserve the prescribed correlations, and a random seed of 1000 was used to preserve the prescribed sampling technique.

Input Rank Correlations Input correlations were assigned between correlated parameters based on guidance provided in

' NUREG/CR-6676 and NUREG/CR-6697.

Output Specifications.

All of the output options were specified.

The PRCC for the peak of the mean dose was used as the measure of the sensitivity of each parameter to the peak of the mean dose.

For the resident farmer scenario, a parameter was identified as sensitive if the absolute value of its PRCC (IPRCCI) was greater than or equal to 0.25 and non-sensitive if the JPRCCJ value was less than 0.25.

These thresholds were selected based on the guidance included in NUREGICR-6676.

Uncertainty Report The RESRAD Uncertainty Report provides regression and correlation coefficients for the peak of the mean dose. The PRCC correlation coefficient has been used to identify sensitive parameters with the llimit set at 0.25. Parameter values are further identified as being positively or negatively correlated to dose by assessing whether the PRCC value is greater than zero or less than zero.

NUREG/CR-6692 and 6697 recommend the use of the PRCC or SRRC for cases where a non-linear relationship and widely disparate scales exists between the inputs and outputs. The NUREG/CR a-

Project: Yankee Rowe License Termination Plan Calculation No. YA-CALC-01-001-03

Subject:

RESRAD 6.21 Sensitivity Analysis for Resident Farmer Scenario-Soil Page: 9 guidance further recommends the use of the PRCC if the strong correlation exists between input parameters.

Table 3 identifies for each radionuclide the sensitive parameters in order of rank, the PRCC values and the R-Squared value. R-Squared, the coefficient of determination presents a measure of the variation in the peak dose explained by the regression on the input parameters involved in the analysis and varies between 0 and 1.

RESRAD 6.21 Sensitivity Analysis for Resident Farmer Scenario-Soil Page: Attachment 1 Page 5 Data from NUREG/CR-6697, Attachment C, Section 3.8, 2nd paragraph of the Discussion Section on pages 3-25 & 3-26, was used to select the appropriate Erosion Rate that corresponds to the Rowe Site slope of 2.86%.

• The data in Table 2-1 below was generated using NUREG/CR-6697's row-crop Erosion Rate of 6.0 E-4 for a 2 % slope. Erosion Rates where then calculated for5.10 and 15 percent slopes using their rate increase factors as specified in the Discussion of Section 3.8 referenced above. As recommended in this section of NUREGICR-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.

3. Humidity in Air The reference, "Regional and Site-Specific Absolute Humidity Data for Use in Tritium Dose Calculations",

Health Physics, Vol.39, pp 31 8-320, 1980 provides a table of absolute humidity for selected locations in the US. These values were calculated from data from the National Oceanic and Atmospheric Administration, 1977, Climatological Data, Annual Summary, volume 28(13), US Dept. of Commerce.

The value of 6.1 g/m3 was chosen for the RESRAD humidity parameter corresponding to the Northeast region in the vicinity of Albany, NY.

4. Average Annual Wind Speed The wind speed and direction, joint frequency distributions from Table 3.3-2 of the YNPS Environmental Decommissioning were used to calculate the average annual wind speed. The mid-range value was calculated for each of the ranges for which data was available. An average wind speed was calculated by summing the product of the mid-range value for each range and the percentage of time the wind was recorded to be within the range. A value of 2.03 m/s was assigned to this parameter.

6. Irrigation Rate. (Evapotranspiration and RUnoff Coefficients)

NUREG/CR-6697 Attachment C, Section 4.3 discusses the Irrigation Rate in terms of the Evapotranspiration Coefficient. Equation 4.3-1 expresses the Evapotranspiration Coefficient as:

Ce = ETr (1-Cr)(Pr) + IRr Where: ETr = the Evapotransporation Rate (m/y)

Pr = the Precipitation Rate (mly)

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

Rearranging this equation, the Irrigation Rate can be expressed as:

IRr = ETr - (1-Cr)(Pr)

Ce The input values for the variables in the equation above follow:

1. YA-REPT-00-002-03, (Ref. 9), cites a value for the average annual Evapotranspiration Rate, ETr, inthe upper Housatonic River basin of 21.6 in/yr or 0.549 m/yr from 1931 to 1960.

2. The Precipitation Rate, Pr, has been assigned a site-specific value of 1.2 in/yr as discussed in

.Section 5 of this Attachment

3. Appendix E,.Table E.1 of Ref. 4 provides the equation below to calculate the Runoff Coefficient, Cr. for an agricultural environment' Table E.1, Runoff Coefficient Values, also lists values for c,, c2 and C3 for various environments:

C,= 1-C -C 2 -C 3 c= 0.1.for hilly land with an average slopes of 46 m/mi (Refer to section 2 of this Attachment for the site slope determination- 20' drop per 700' run or 46 m/mi).

c2= 0.2 for intermediate combinations of clay and loam as identified at the site in Ref. 8.

c3 = 0.1 for cultivated lands which also fits the scenario for the site.

Cr=1-0.1-0.2-0.1=0.6

4. NUREG/CR-6697, Attachment C, Section 4.3-Evapotranspiration Coefficient, Ce, defines this parameter as the ratio of the total volume of water (a combination of evaporation from soil surfaces and transpiration from vegetation) transferred to the atmosphere to the total volume of water available within the root zone of the soil. The NUREG/CR recommends -the use of a uniform distribution with minimum and maximum values of 0.5 and 0.75, respectively and with 0.625 as median. Any selected value for the irrigation rate should satisfy the Ce minimum to maximum range

Project: Yankee Rowe License Termination Plan Calculation No. YA-CALC-01-001-03

Subject:

RESRAD 6.21 Sensitivity Analysis for Resident Farmer Scenario-Soil Page: Attachment 1 Page 10 Making the appropriate substitution of minimum and maximum values of Ce into the rearranged Equation 4.3-1 results in the following range for the Irrigation Rate, IRr.

7. Field Capacity: Contaminated Zone, Unsaturated zone 1 and Saturated zone The "Data Collection Handbook to Support Modeling the Impacts of Radioactive Material in Soil," (Ref. 11) defines the relationship of field capacity (residual water content) to effective porosity. The field capacity is the ratio of the volume of water retained in the soil sample, after all drainage has ceased, to the total volume of the soil sample. Equation 4.4 of Ref. 11 relates Total and Effective Porosity to Field Capacity as follows:

Effective Porosity = Total Porosity - Field Capacity Rearranging this equation:

Field Capacity = Total Porosity - Effective Porosity The total and effective porosity values for the various zones are the mean values of the NUREG/CR-6697 distributions for sand.

Table 7- 1 Field Capacity Zone I Soil Type Total Porosity. Effective Porosity Field Capacity Contaminatedl sand 0.43 0.383 0.047 Unsaturated/ sand 0.43 0.383 0.047 Saturated! sand 0.43 0.383 0.047

8. Saturated Zone Hydraulic Gradient NUREG/CR-6697, Attachment C, Section 3.6 -Hydraulic Gradient, 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= h1 -h2 Where hi and h2 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. This methodology was followed in YA -REPT-00-002-03, Hydrogeological Parameter Estimates for Radiation Dose

Modeling, (Ref. 9) to determine the average hydraulic gradient across the site. An average value for the site was calculated from three separate hydraulic gradient determinations as follows in Table 8.1. Figure 8.1 shows the well locations.

9. Well Pumping Rate NUREG/CR-6697, Attachment C, Section 3.10 states that."A site-specific input distribution for well pumping rate can be determined as the sum of individual water needs." The household use component is calculated from the Domestic Water Use discussed in YA-REPT-00-002-03, Ref. 9. To support the assumption that irrigation of pasture is not a common practice in New England, the USDA 1992 Census of Agriculture, State Data, was reviewed and showed that in 1992 in all of Massachusetts 19622 total acres of cropland was irrigated and 287 total acres of pastureland was irrigated. In 1997 only one farm, in Franklin County, claimed irrigation of pasture.
