BHI ENERGY ENGINEERING CALCULATION RESRAD-Build Input Parameter Sensitivity Analysis - OCS ENG-OCS-002 Revision: 1 March 6, 2024 Prepared by:

BHI Energy l Power Services 97 Libbey Industrial Pkwy Weymouth, MA Prepared by Approved by

BHI Engineering ENG-OCS-002 RESRAD-Build Input Parameter Sensitivity Analysis-OCS Rev. 1 Page 1 of 24 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 evaluation of the building occupancy scenario using the RESRAD-Build code (version 3.5). 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 DCGL calculations by determining and assigning reasonably conservative input values from the results of RESRAD-Build probabilistic analyses. Thus, the results of this calculation support the development of building surface derived concentration guideline levels (DCGLs) for the Oyster Creek Station (OCS) site.

2.0 APPLICABILITY This calculation addresses only the sensitivity analysis for input parameters for the building occupancy scenario as defined for the OCS site.

The RESRAD-Build Users Manual [3.2] provided guidance for code operation.

The sensitivity analysis for RESRAD-Build 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 probabilistic modules in RESRAD-Build permit the user to identify input parameters that have a significant impact on dose with

BHI Engineering ENG-OCS-002 RESRAD-Build Input Parameter Sensitivity Analysis-OCS Rev. 1 Page 2 of 55 changes in input values. Verification of the RESRAD-Build code is documented in the RESRAD-Build Users Manual and testing for the probabilistic codes is discussed in NUREG/CR-7267 [3.3].

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.

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/CR-5512, volume 3 [3.4.2], NUREG/CR-7267, or the RESRAD-Build Users Manual. 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, NUREG/CR-7267, NUREG/CR-6755 [3.6], or assigned a deterministic value from NUREG/CR-5512, volume 3, NUREG/CR-7267, or NUREG/CR-6755. 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, NUREG/CR-7267, NUREG/CR-6755, or the RESRAD-Build Users Manual.

RESRAD-Build parameter sensitivity analysis was performed for each radionuclide-of-concern (ROC).

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. NUREG/CR-7267 and NUREG/CR-6697 recommend the use of the PRCC for cases where non-linear relationships exist. 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 equal to or greater than 0.1. 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 buildings/structures at the OCS site. The approach of assigning 25th and 75th percentile values of a sensitive parameters distribution has been found acceptable as a reasonably conservative approach by the U.S. Nuclear Regulatory Commission (NRC) and State regulators.

5.0 ASSUMPTIONS AND INPUT

BHI Engineering ENG-OCS-002 RESRAD-Build Input Parameter Sensitivity Analysis-OCS Rev. 1 Page 3 of 55 5.1 Assumptions 5.1.1 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 [3.4.2]. 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.

5.1.2 Site-specific suite of ROCs has been identified for the OCS site [3.7]. The OCS ROCs (and their progeny where applicable) are shown in Table 1 below.

5.1.4 The representative room modeled for the OCS site is based on the room described for the occupancy scenario in Volume 1 of NUREG/CR-5512 and in NUREG/CR-6755

[3.6]: an 8m by 8m room with 3m walls. This room includes 6 area sources (i.e. floor, 4 walls, and ceiling).

5.2 Input Table 2 summarizes the classification, prioritization, values, and their bases for all input parameters.

Values from NUREG/CR-5512, volume 3, and NUEG/CR-7267, NUREG/CR-6755, were assigned for the following scenario-defined parameters:

Exposure duration: 365.25 d

BHI Engineering ENG-OCS-002 RESRAD-Build Input Parameter Sensitivity Analysis-OCS Rev. 1 Page 4 of 55 Indoor fraction: 0.267 Inhalation rate: 33.6 m3/d Receptor location (center of room, x, y, z coordinates): 4m, 4m, 1.0m Air fraction: 1.0 for H-3 (triangular distribution used for all other nuclides)

Removable fraction: 0.1 (all ROCs)

Room area: 64 m2 Room height: 3 m Receptor location: center Location of center of source: center point of floor, walls, and ceiling Statistical distributions from NUREG/CR-7267 and NUREG/CR-6755 provided input for:

deposition velocity, air exchange rate for room, re-suspension rate, indirect ingestion rate, air release fraction, 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 [3.8]. 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 8m by 8m by 3m.

6.2 Direct ingestion rate (h-1) is based on the direct ingestion rate given in NUREG/CR-6755:

4.91E-07 h-1.

6.3 Using the dimensions for the modelled room, the locations of the centers of the sources were determined as the mid-point on the X, Y, and Z-axes.

6.4 RESRAD-Build v3.5 results: Table 2 summarizes the input used in RESRAD-Build code executions. Appendix A provides copies of selected pages from the RESRAD-Build uncertainty reports.

6.4.1 Each ROC listed in Table 1 was evaluated in separate code executions.

BHI Engineering ENG-OCS-002 RESRAD-Build Input Parameter Sensitivity Analysis-OCS Rev. 1 Page 5 of 55 6.5 PRCC values were reviewed against the sensitivity criterion (i.e., PRCC0.1). The building air exchange rate, and the air release fraction were identified as sensitive input parameters for all ROCs. Table 3 summarizes the sensitive parameters by radionuclide.

NOTE In DCGL calculations, 25th or 75th percentile values will be input values for ROCs for which one of the above-listed parameters was identified as sensitive. The 50th percentile value will be used as input if a parameter is not identified as sensitive.

6.6 The 25th, 50th, and 75th percentile values are obtained from the RESRAD-Build probabilistic results. Table 4 presents these values.

7.0 CONCLUSION

7.1 The building air exchange rate, deposition velocity, resuspension rate, ingestion rate, time of source removal, and the air release fraction are sensitive parameters for one or more of the ROCs in the modelling of the building occupancy scenario using RESRAD-Build.

7.2 The building air exchange rate (LAMDAT), deposition velocity (UD), resuspension rate (DKSUS), and ingestion rate (INGE) characterize the room. The uncertainty in the input values for each of these parameters will be considered in DCGL calculations by applying the 25th or 75th percentile value to all 6 sources if a parameter was identified as sensitive for any one of the 6 sources.

7.3 The source removal time (RFO) and air fraction (AIRFR) characterize the source. Use of the 25th and 75th percentile values will provide conservative input in DCGL calculations to consider the uncertainty associated with input for sensitive parameters.
