Subject:
Docket 50-156, License R-74 Submission of Revised Dose Estimates for License Renewal to Facility License No. R-74, University Of Wisconsin Nuclear Reactor TAC No. ME1585
Dear Sirs:
On April 10, 2009, the University of Wisconsin Nuclear Reactor (UWNR) submitted revised dose estimates for the conversion from high enriched uranium (HEU) fuel to low enriched uranium (LEU) fuel in response to the Commission's request for additional information, specifically RAI #43, dated February 26, 2009.
Following telephone communications with Commission staff on February 3, 2011 it was agreed to provide revised dose estimates for all analyzed accident scenarios, including those not addressed in RAI #43. For completeness, a comprehensive summary of all revised doses have been compiled below.
The dose calculations reflect the LEU 30/20 core design as well as methodologies of calculation in the LEU Conversion Analysis Safety Analysis Report (LEU SAR) as supplemented by letter dated April 10, 2009. The results reported in the LEU SAR were updated to use more appropriate fission product release fractions. The LEU SAR calculated the release fraction based on the maximum centerline temperature, but .a more accurate approach is to use an effective release fraction calculated by volume integrating the release fraction equation across the fuel temperature distribution, both axial and radial. This is appropriate since the release fraction measurements were made Page 1 of 4
I..-.
- on small isothermal fuel samples (General Atomics, "The U-ZrH, Alloy: Its Properties and Use in TRIGA Fuels," GA E-117-833, February 1980, page 5-5). The revised release fractions are 7.825E-5 BOL, 7.630E-5 MOL, and 6.125E-5 EOL, approximately 10%
of the values listed in chapter 13 of the LEU SAR.
The table numbering represents the original numbering in the LEU SAR.
