- 9. Assumptions
- 1. Assume the resin release fraction to be either 10% or 100%. 10% should be conservative, while 100%
produces a limiting case.
- 2. Accident time interval = 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> (Assumption. Given that atmospheric dispersion is modeled as instantaneous and no decay over the release time is modeled, the cumulative dose is independent of the release interval provided that the dose is integrated over the entire release interval.)
- 3. No decay from the date of plant shutdown is modeled. This is a conservative assumption 729292 (Mar 2012)

- 10. Methodology The integrated dose over a given time period is equal to the sum of the external dose (EDE) and the internal dose (CEDE). The EDE for a given nuclide is calculated as the product of the curies released, the X/Q, and the effective dose coefficient for air submersion. The CEDE for a given nuclide is calculated as the product of the curies released, the X/Q, the inhalation rate, and the committed dose equivalent per Unit Intake coefficient.
Two cases will be evaluated, corresponding to the 10% and 100% release fractions.
- 11. Calculations An example calculation of the EDE dose from H-3 is as follows.
EDE = (1.77E-2 Ci)(2.23E-4 sec/m3)(3.13E-19 Sv m3/Bq sec)(3.7E10 Bq/Ci)(100 Rem/Sv) = 4.58E-12 Rem An example calculation of the CEDE dose from H-3 is as follows.
CEDE = (1.77E-2 Ci)(2.23E-4 sec/m 3)(3.5E-4 m3/sec)(1.73E-11 Sv/Bq)(3.7E10 Bq/Ci)(100 Rem/Sv) = 8.84E-8 Rem 729292 (Mar 2012)

- 12. Acceptance Criteria(OPTIONAL)
The dose to an individual at the EAB should be less than 1 Rem integrated over the period of the radiological release. This limit is consistent with the Protective Action Guide (PAG) for the Early Release phase of an atmospheric release of I Rem defined in Section 2.3.1 of Reference 3.

- 13. Resuls and/orConclusions Both the 10% release and 100% release cases produce dose consequences at the site boundary that are less than the 1 Rem acceptance criteria (0.015 Rem and 0.148 Rem, respectively). These results are bounding values because each value is based on a bounding resin curie content and no decay of the resin following plant shutdown.

Comments: (Attach additional pages if needed)
This calculation was prepared, reviewed, and approved in accordance with Dominion fleet procedure CM-AA-CLC-301 and GaRD CM-AA-CLC-301-1001. A Kewaunee Owners Review of this calculation is required prior to use in accordance with Kewaunee Procedure CM-KW-REV-101.
Reviewer's Comment During the review process, decay chains for the isotopes present in the resin were evaluated for daughter isotope contributions. It was determined that most isotopes decayed either to stable isotopes or to isotopes with half-lives >> 10,000 years. Exceptions were identified for the following daughter isotopes: Y-90, Te-125m and Pr-144.
Adding dose consequences for Y-90, Te-125m, and Pr-144 to the results presented in Tables 1 and 2 has no effect on the total dose calculated (assuming secular equilibrium and decay fractions of 1, 0.23 and 1, respectively, from their parent isotopes).
