STAGING 0F HITTMAN LINERS IN THE WASTE HANDLING AND PACKAGING FACILITY SAFETY EVALUATION INTRODUCTION The Waste Handling and Packaging Facility (WHPF) is designed to process and package radioactive and contaminated items generated by the THI-2 cleanup.
The NRC staff found the proposed operation of the WHPF acceptable and documented approval in the July 10, 1986 safety evaluation. (reference 2).
By references 3 and 4 General Public Utilities Nuclear (GPUN) Corporation, the licensee, requested that the radionuclides mix and inventory allowed in the WHPF be updated to reflect the change in the mix as the cleanup and defueling progressed.
The NRC staff reviewed these changes, found them acceptable and approved them in reference 5 The current proposal would allow the use of the WHPF for inspection of two previously packaged liners. The liners contain 274 and 228 curies respectively with strontium and cesium being the principal radionuclides.
The resin and sand containing the radionuclides have been solidified in concrete inside the liners.
EVALUATION The staff has evaluated the potential offsite dose consequences of potential accidents associated with staging the two Hittman liners in the WHPF and compared the results with the previous analyses.
The worst case previously assumed was 7.5 Ci of " normal" waste containing 90.3% CS-137, 2.4% Cs-134 and 7.3% Sr-90 and an additional 7.5 Ci of "defueling" waste containing 50% Sr-90, 10% Cs-134, 34% Cs-137 and 6% transuranic (actinide) activity.
The worst case accident previously analyzed was a fire in which paper, rags, and decontamination materials containing the radionuclides burned.
The resultant hypothetical worst case offsite dose commitment was 119 mrem.
In the current case the radionuclides mix is 89.2% Sr-90, 7.3% Cs-137, 2.2%
Sb-125 and 1.3% other radionuclides with 0.1% being actinides (including uranium and transuranic).
Since the concrete will not burn the worst case accident considered was a drop of the liner.
The resultant hypothetical offsite dose commitment was 7 mrem. This is well within the bounds previously analyzed and is a small part of the limits in 10 CFR 100.
CONCLUSION The staff concludes that the staging and inspection of the Hittman liners in the WHPF does not pose a significant risk to the health and safety of the public and does not involve a significant hazard.
