From 1955–1988, low-level waste solutions from the processing of uranium and irradiated nuclear fuel were discharged into unlined earthen storage basins at the Savannah River Site (SRS) F-Area [1]. Over the decades, radioactive contaminants including uranium and iodine-129 (I-129) have leaked out of the basins and into the groundwater of the surrounding wetlands, and are now present at levels that exceed regulatory thresholds.
Congratulations to Jaewon Lee!

Jaewon Lee, one of our graduate students from the UC Berkeley Department of Nuclear Engineering won 3rd place in the student competition at the recent IEEE Nuclear Science Symposium and Medical Imaging Conference, one of our major conferences of the year.
He received this award for his outstanding presentation titled “Single Detector 3D Source Imaging Using a Kullback-Leibler Divergence Based Prior”. This work which he performed in collaboration with ANP’s Tenzing Joshi and Ren Cooper improves the localization and mapping of radioactive materials in three dimensions in unconstrained environments overcoming limitations in conventional approaches. This is a wonderful accomplishment and a well-deserved award for him.
