In the D&D space, UCOR is currently working to demolish a second reactor at ORNL, the Low Intensity Test Reactor. This follows demolition of the Bulk Shielding Reactor in 2022, which was the first-ever demolition of a reactor on the Oak Ridge Reservation. In addition, crews continue deactivating a number of reactors, including the Experimental Gas-Cooled Reactor and the Oak Ridge Research Reactor. Workers are also deactivating the complex of facilities known as Isotope Row. After removing the west cell bank at the former Radioisotope Development Lab, crews are deactivating the “hot cell” in the east cell bank for demolition next year.
At LGWO, workers continue to upgrade the infrastructure. Recently, a new zeolite treatment system was completed consolidating radiological and non-radiological wastewater treatment capability into one facility, reducing operational costs. The upgrade makes it possible to decommission other outdated facilities.
Our other work includes maintaining the Molten Salt Reactor Experiment facility, providing upgrades for the 3001 Graphite Reactor, and other system and facility upgrades as needed.
