RESRAD-BUILD v3.21 Sensitivity Analysis for Building Occupancy Page 3 accomplished through the use of the probabilistic modules in RESRAD-BUILD V 3.21. 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 NUREGICR- 5512 vol.3, -6697 or -6755. Physical parameters are assigned site-specific values or are treated stochastically and assigned a distribution from NUREG/CR-6697or 6755. The distribution statistics for stochastic parameters are used as the input to the probabilistic module of RESRAD-BUILD.

The Partial Rank Correlation Coefficient (PRCC) is used as the measure of the dose sensitivity to variations in the input parameter.

RESRAD-BUILD v3.21 Sensitivity Analysis for Building Occupancy Page 6 D. ASSUMPTIONS

1. Radionuclide List A probabilistic run of the RESRAD-BUILD code was performed for the radionuclides listed in Table 2. This list of radionuclides was developed by consideration of historical site data, waste stream analysis and source terms in NUREG guidance to encompass the significant radionuclides that may present a significant dose impact (Ref 9).

2. Conceptual Model Underlying the Dose Model The conceptual model was developed based on site demolition plans and the characteristics of rooms/partial rooms expected to remain at the time of license termination. The model is comprised of a room, with dimensions representing an average wail to remain at the site. The four walls and floor of this room are assumed to be contaminated uniformly and to equal levels. This is considered to be a conservative assumption as normally the amount of contamination on room walls is less than that on the floor and decreases as the distance from the floor increases. No contaminated ceilings are included in the model, as partial rooms/rooms remaining at the time of license termination will either have no ceiling or will be covered with a ceiling constructed of new uncontaminated building materials. Attachment I provides the details for the determination of the room dimensions.
3. Dose Model: Building Occupancy Scenario The building occupancy scenario defined in NUREG/CR-5512, Volumes 1,2, and 3 and NUREG-1727 will be used to determine Building Surface Derived Concentration Guideline Levels, DCGL. This scenario is chosen because the basic premise of the building occupancy model for buildings decontaminated to an unrestricted release level is that this model will yield DCGL values that meet all the requirements for IOCFR20.1402.

The decommissioning of the Yankee Rowe site involves the demolition of many of the structures within the Radiation Control Area (RCA). The surfaces of all structures and rooms remaining will be surveyed for residual radioactivity. The threshold for the amount of residual radioactivity that can remain on a building surface at the time of license termination is based on a maximum annual dose of 25 mrem to members of the critical group. This scenario assumes that the critical group consists of light industrial workers working in the building following license termination.

Prior to use, the operability of the RESRAD-BUILD Version 3.21 code was verified in accordance with site procedures. The code, as used in this analysis, considers five exposure pathways to occupants of a building from residual radioactivity:

. External exposure directly from sources

  • External exposure to deposited material
  • External exposure due to air submersion
  • Inhalation of airborne radioactive particulates
  • Inadvertent ingestion of riadioactive material directly from the sources

RESRAD-BUILD v3.21 Sensitivity Analysis for Building Occupancy Calculation No YA-CALC-OD-003-03 Page 7 I E. METHODIBODY OF CALCULATION Numerous input parameters are required by RESRAD-BUILD to calculate the dose to a building worker from various exposure pathways. Using the probabilistic modules in RESRAD-BUILD, a sensitivity analysis allows the identification of parameters with the greatest potential to effect the dose. The guidance published in NUREGICR 6676, - 6697, - 6692 and 6755 has been used to develop an approach for selecting parameter values. This process is described below.

1. Parameter Selection Process The conceptual and dose models discussed above are quantified by a set of input parameters in the RESRAD-BUILD code. Incorporated within RESRAD-BUILD v3.21 are probabilistic modules that allow the evaluation of dose as a function of parameter distributions. The process for classifying and selecting input parameter values was developed in accordance with the guidelines presented in NUREG/CR-6755, -6676, -6692 and -6697.

NUREGICR-6755 provides the technical basis for calculating doses for the Building Occupancy scenario using the probabilistic RESRAD- BUILD code and also provides input parameter information that has been updated since the publication of NUREG/CR 6697. A schematic flow diagram of the parameter selection process is provided in Figure 1. Each step of the selection process is discussed below.

Classification (TvDe)

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/CR-6697 approach to prioritizing parameters was applied in this calculation. The priority of a particular parameter is based upon:

  • The relevance of the parameter in dose calculations,
  • The variability of the dose as a result of changes in the parameter value,
  • The parameter type and
  • The availability of parameter-specific data.

Priority 1 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.

Treatment Input parameters are treated as either deterministicu 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 were treated as deterministic and were assigned values from NUREGICR-5512, Volume 3, NUREG/CR-6697, NUREG/CR 6755 (if updated), or the RESRAD default library.
  • Parameters for which site-specific data is available were treated as deterministic.
  • The remaining physical parameters, for which no site-specific data is available, were assigned values based on priority. Priority I and 2 parameters were treated as stochastic and were assigned probability distributions from NUREGICR-6697or.6755, or a deterministic value from NUREG/CR-5512 vol.3, 6697or 6755. The priority 3 physical parameters were treated as deterministic and were assigned values from NUREG/CR-5512, Volume 3, NUREG/CR-6697, NUREG/CR-6755, or the RESRAD default library.

2. Parameter Value Assignment Behavioral and Metabolic Parameters Scenario-defined parameters are assigned values recommended in NUREG/CG-5512 vol. 3 for the building occupancy scenario and include:

Exposure duration: 365.25 days Indoor fraction: 0.267 Time Fraction: 1 Breathing rate: 33.6 m3/day Receptor location: Center of room at a height of Im Direct ingestion rate: 1.34E-06 hr-'

Calculated from NUREG/CR 5512 ingestion rate = 1.IE-04 m2/hr divided by the total source area available to be inadvertently but directly ingested = 82.03 m2 .

Dose conversion factors: FGR1 I and FGR12 values are used Behavioral parameters not Included in the NUREG1CR-5512 vol. 3 building occupancy scenario but used in the RESRAD-BUILD model include:

Air exchange rate for room: 1.52 hr 1- (updated in NUREG/CR-6755)

Indirect ingestion rate: 0 to shut off the pathway.

Only direct ingestion is modeled to be consistent with the building occupancy direct ingestion pathway utilized in the NRC's D&D computer code.

Air fraction: 0.07 for solids; 1.0 for H-3 (NUREG/CR-6697)

Physical Parameters Site and scenario information is used to determine physical parameter values when it is available. For physical parameters identified as a Priority I or 2 (high and medium priority) a parameter distribution from NUREGICR-6696,

- 6755 or a deterministic value from NUREG/CR-5512 vol.3, -6696, - 6755 is used. For physical parameters identified as Priority 3 (low priority) a value isassigned from NUREG/CR-5512 vol.3, -696, or -6755.

A three dimensional model is selected in RESRAD-BUILD to represent a typical room to remain at the YNPS site. A ceiling is not modeled since all structures remaining following demolition and license termination will be covered with new uncontaminated material. The average room is defined by the dimensions of 4.44 mwide by 4.44 m long and 3.51 m high. Attachment I provides information on the rooms/partial roams to remain on the YNPS site. Each wall and floor surface is assumed to have uniform contamination over the entire surface.

Site and scenario defined parameters include:

Room area: 4.4 4m x 4.44 m = 19.71 m2 Room height: 3.51 m Location of sources: Center of four walls and floor (See Attachment 1,Section 2,Table 1.3- Receptor and Center of Source Locations)

Area of sources: Floor = 19.71 m2 4 Walls = 15.58 m2 each Number of sources: 5 Type of source: Area Direction of source: See Attachment 1, Section 2, Table 1.3- Receptor and Center of Source Locations Receptor location: See Attachment 1, Section 2, Table 1.3- Receptor and Center of Source Locations Removable fraction: 0.1 (NUREG/CR-5512 building occupancy scenario and NUREG-1727, Table C7.1)

RESRAD-BUILD v3.21 Sensitivity Analysis for Building Occupancy Page 9 Physical parameters assigned a statistical distribution include:

Deposition velocity: NUREG/CR-6755 Resuspension rate: NUREG/CR-6755 Time for source removal: NUREG/CR-6755 An Input correlation of 0.9 is established between the deposition velocity and the resuspension rate based on the guidance in NUREGICR-6676, Section 8.2. Because the sources are constructed of the same material and subject to the same environment, an input correlation of 0.9 is established for the time for source removal between sources.

Attachment 2, Table 2.1 provides a listing of all the input parameters and the results of the parameter classification and selection process. All assigned values or distributions and the basis of each is also provided in Table 2.1.

3. RESRAD- BUILD Sensitivity Analyses Runs The sensitivity runs were performed using the RESRAD- BUILD V3.21 code. The data in Attachment 2, Table 2.1 were used as parameter inputs to the Build code and, where appropriate, the probability distribution statistical parameters were entered into the probabilistic modules of the Build code. The code was run individually for all the radionuclides listed in Table 2 at a concentration of I pCi/m 2. The time of the maximum dose for all nuclides except Pu-241 isdefined at an evaluation time of T = year. For Pu-241 the maximum dose occurs at T = 9 years.

Uncertainty Report The RESRAD- BUILD Uncertainty Report provides regression and correlation coefficients for the average dose at the user defined evaluation time. The PRCC correlation coefficient has been used to identify sensitive parameters with the limit set at 0.1. 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 guidance recommends 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 NUREGICR guidance further recommends the use of the PRCC if the strong correlations exist between input parameters.

Table 3 identifies, for each radionuclide, the sensitive parameters in order of rank, the coefficient of determination and the values of the PRCC.

1. Room Dimension An inventory of the rooms and partial rooms that would remain on site following Phase I of the DEMCO demolition project (Ref. 1.1) was used as the starting point in determining room dimensions. Wall dimensions were determined from Site Drawings showing the building locations, building elevations and dimensions.

Ceilings are not included in the model, as partial rooms/rooms remaining at the time of license termination will either have no ceiling or will be covered with a ceiling constructed of new uncontaminated building materials.

The average wall dimension was calculated using an Excel Spreadsheet and considers all the remaining walls. A total of twenty-six walls were used to determine the scenario room length and width. The 40.5 meter long Primary Auxiliary Building (PAB) South Wall was excluded from the average wall distance calculation.

This wall, which extends the entire length of the PAB was excluded because it is unlikely it would be used as one side of a single room built in the future. This data and the calculated wall length and height are shown in Table 1.1 - Remaining Room / Wall Dimensions. The portion of the room to remain is highlighted.

The average wall dimension (meters) from Table 1.1 was used to calculate the scenario room-floor surface area (meters 2 ) as follows:

Room area = (4.44) x (4.44) = 19.71 meters2 The wall surface area in square meters was calculated as follows from the average wall length and height in meters from Table 1.1:

Wall area = (4.44)x (3.51) = 15.58 meters2 The room and wall surface areas and the wall height are used as input to the RESRAD-BUILD code to define the five source terms.

All wall dimensions were obtained from plant drawings as referenced in Table 1.2 - Remaining Structures and Drawing Reference.

2. Source Configuration NUREG/CR-6755, Section 4.1, describes three principal assumptions inherent in the Building Occupancy scenario: a fixed room area, uniform surface contamination, and the receptor location at the center of the floor at a height of 1 m. The configuration of the receptor and sources isillustrated in Figure 1.1. The RESRAD- BUILD input parameters, receptor location and center of source coordinates, are provided in Table 1.3 Figure 1.1.

3. Direct Ingestion Rate The source specific input parameter, Direct Ingestion Rate, isdescribed in RESRAD-BUILD as the direct ingestion rate of the source by any receptor in the room. Each receptor will ingest the source at a rate determined by the ingestion rate and the amount of contamination in the source at that time. Direct ingestion ispossible only if the receptor and the source are in the same room and has units of 1/hr for surface area sources.

NUREG 5512, volume 3 defines the average ingestion rate of 1.1E-4 m2Ihr as representative for the average individual in an industrial setting. The Direct Ingestion Rate for use in the Building Occupancy Scenario is calculated based on the total room source area as follows:

Direct Ingestion Rate = (1.1E-04 m2/hr) / (Source Area)

= (1.1 E-04 m2/hr) (82.03 M2 ) = 1.34E-06 hr '

The direct ingestion defined in this manner used in conjunction with an indirect ingestion rate set to zero,'

adequately models the Building Occupancy Ingestion pathway.
