Remedial action for a depleted uranium and TH waste pond

Aerojet Heavy Metals Company (AHMC) completed the decommissioning program for an inactive evaporation pond at its facility near Jonesboro, Tennessee during the summer of 1985. The pond had previously been used for process liquid wastes containing depleted uranium (DU) and thorium contamination. The remedial program included a series of projects by several companies. AHMC coordinated and administered all phases of the program. Rogers and Associates was responsible for the final phases of the program. The use of full-time construction monitoring and surveillance and materials testing provided assurance and documentation that the remedial project was completed in accordance with the design criteria and the construction specifications. Detailed certification sampling indicated that the associated project area had been cleaned up according to the specified radiological guides. The inventory in the 30,000 m/sup 3/ disposal cell is about 0.48 TBq (13 Ci) of U-238 as depleted uranium and 0.03 TBq (1 Ci) of Th-232
