Underwater Determination of Radionuclide Levels in 105-KE Basin Floor and Walls Using a Gamma-Ray Detector System

[摘要] Activities to remove spent fuel, sludge and debris from K East Basin have begun. Once all the radioactive hazards (i.e., fuel, sludge and debris) are removed from the basin, the basin water will be removed and the basin will be turned over to a deactivation and decommission contractor. However, the specific approach to achieving this end state is dependent on knowledge of contamination levels in the concrete walls and floor once the water is removed. PNNL researchers have developed a one-of-a-kind technology for performing non-destructive evaluation of the highly contaminated K East fuel storage basin for the purpose of determining concrete contamination levels from selected wall and floor locations below the basin waterline.
