4.0 METHOD OF CALCULATION The operability of the RESRAD-Build code was verifi ed on each computer used for code executions in accordance with Engineering procedure ENG-AP-02, Verification of Software Operability [3.1]. The RESRAD-Build users manual [3.2] prov ided guidance for code operation.

BHI Energy Engineering Calculation ENG-OCS-002 [3.3] documents the probabilistic (sensitivity) analyses performed for the numerous RESRAD-Build inpu t parameters; this calculation incorporates those results. Six input parameters are identified in ENG-OCS-002 as sensitive (i.e., parameters that have a significant impact on the calculated dose with a change in input value): deposition velocity, resuspension rate, room air exchange rate, indirect ingestion rate, air release fraction, and time for source removal.

In addition, BHI Energy Engineering Calcula tion ENG-OCS-002 provides recommendations for reasonably conservative values for the sensitive parameters: 25 th and 75th percentiles of the input parameter distributions. Use of 25 th and 75th percentiles values has been found by the U.S. Nuclear Regulatory Commission and state regulators as an acceptable method for providing assurance that the DCGL calculations account for the uncertainties associated with identified sensitive paramet ers. The input values used in this calculation are consistent with both the selected scenario and the results of the sensitivity analyses.

RESRAD-Build version 3.5 code runs were performed for each of the radionuclides-of-concern (ROCs) for the OCS site. The RESRAD-Build results (i.e., mrem/y per 1.0 pCi/m 2) were used as conversion

B HI Power Services Page 1 of 27 energy BHI Energy Engineering ENG-OCS-004 Oyster Creek Building Surface DCGL Values Rev. 0

factors (CF) to develop DCGL values that corresponded to 25 mrem/y (the dose criterion for unrestricted release established in 10CFR20.1402:). This was accomplished as follows:

(25 mrem/y)/(RESRAD-Build CF (mrem/y per pCi/m 2)) = DCGL25 (pCi/m2).

Unit conversion of DCGL values from pCi/m 2 to dpm/100 cm 2 was accomplished as follows:

DCGL25 (pCi/m2) x (2.22dpm/1pCi) x (1m 2/10000cm2) x 100 = DCGL25 (dpm/100cm2)

5.0 ASSUMPTIONS AND INPUT

5.1 Assumptions Exposure Scenario: The the building occ upancy scenario defined in NUREG/CR-5512, volume 1 [3.4.1], including the following exposure pathways:

o direct external exposure from the source (i.e., residual radioactive material on the floor, walls, and ceiling),

o external exposure from deposited airborne material, o external exposure due to air submersion, o exposure due to inhalation of ai rborne radioactive material, o indirect ingestion of radioactive material on the sources and material deposited on the surfaces.

The ROCs identified for the OCS site are shown in Table 1 below.

The scenario room defined in NUREG/CR-5512 Volume 1, NUREG/CR-6755 [3.6], and NUREG/CR-7267 [3.7] is modeled in these calcula tions. The dimensions for the scenario-defined room are: 64m 2 in area with 3m walls (8m by 8m by 3m). The room contains 6 area sources: floor, 4 walls, and ceiling.

5.2 Input Values from NUREG/CR-5512, volume 3 [3.4.2], NUREG/CR-6755, and NUREG/CR-7267 were assigned for the following parameters:

o Exposure duration: 365.25 d o Indoor fraction: 0.267 (= (45h/week

  • 52 weeks/y)/(24 h/day
  • 365.25 days/y))

o Breathing rate: 33.6 m 3/d o Receptor location (center of room): 4.0m, 4.0m,1.0m o Air release fraction for H-3: 1.0 o Removable fraction: 0.1 o Room area: 64m2 (8m by 8m) o Room height: 3m o Receptor location: center o Location of center of source: center point of floor, walls, and ceiling Direct ingestion rate, 4.91E-7 h -1, was taken from NUREG/CR-6755.

BHI Energy Engineering Calculation ENG-OCS-002 identifies sensitive RESRAD-Build parameters for each ROC. The RESRAD-Build parameters identified as sensitive for one or more of the OCS ROCs are:

o deposition velocity o resuspension rate o room air exchange rate o indirect ingestion rate o air release fraction o time for source removal 25th or 75th percentile values (determined in E NG-OCS-002) were used as reasonably conservative input values for ROCs for whic h one of the above-listed parameters was identified as sensitive. The 50 th percentile value was used as input if a parameter was not identified as sensitive.

Table 2 summarizes the 25 th, 50th, and 75th percentile values and identifies the ROC to which each percentile value was assigned.

Table 3 summaries the input values for all the RESRAD-Build parameters, including the application of the 25 th/50th/75th percentile values by ROC.

6.0 CALCULATIONS AND RESULTS 6.1 Location of the center of source: The center of each source was determined based on the dimensions for the scenario-defined room. The locations were determined as the mid-point of the dimension values for the X, Y, and Z-axes.

6.2 Table 3 summarizes the input used in e ach RESRAD-Build code execution.

6.2.1 Each of the ROCs listed in Table 1 was ev aluated using an initial concentration of 1.0 pCi/m2 in separate code executions.

6.2.2 For all ROCs except Pu-241, the maximum dose occurred in the first time interval (see selected pages of the RESRAD-Build reports in Appendix A). For Pu-241,

B HI Power Services Page 4 of 27 energy BHI Energy Engineering ENG-OCS-004 Oyster Creek Building Surface DCGL Values Rev. 0

the maximum dose may occur at a later time. Multiple time intervals were used for Pu-241 to assure that the maximum dose was used to develop the DCGL value.

RESRAD-Build results at the various time intervals are summarized in Table 4.

6.3 The maximum doses shown in bold font in Table 4 were used to as the radionuclide-specific CF with units of mrem per pCi/m 2 for developing the DCGL values, which are presented in Table 5.

6.3.1 Column 2 in Table 5 presents the annual do se associated with a concentration of 1.0 pCi/m2 as calculated using the RESRAD-Build code. For each radionuclide, DCGL values corresponding to the 10CFR20.1402 radiological criterion, 25 mrem/y (designated as DCGL 25), were calculated as follows:

(25 mrem/y)/radionuclide-specific CF (mrem/y per pCi/m 2) = DCGL25 (pCi/m2)

The resulting DCGL 25 values are shown in column 3 of Table 5.

Column 4 of Table 5 presents the unit conversions of the DCGL 25 values to values with units of dpm/100cm 2 (designated in Table 5 as DCGL).

DCGL25 (pCi/m2)

  • 2.22 dpm/1pCi
  • 1m 2/10000cm2
  • 100 = DCGL (dpm/100cm 2)

Note: The DCGL values in Table 5 can be adjusted to meet a revised release criterion by multiplying by the ratio of the revised release criterion (mrem/y) to 25 mrem/y. If administrative reduction is desired, the DCGL values can be reduced by multiplying by the desired administrative reduction factor.
