Work plan for denaturing waste in the Old Hydrofracture Tanks at Oak Ridge National Laboratory, Oak Ridge, Tennessee

PDF Version Also Available for Download.

Description

The Environmental Management Program at Oak Ridge National Laboratory (ORNL) is managing a project to remove the contents of the Old Hydrofracture (OHF) Tanks, located in Melton Valley. CDM Federal is responsible for sluicing the sludge and supernate from the OHF Tanks and transferring the slurry into the Melton Valley Storage Tanks (MVSTs), ORNL`s active liquid low-level waste system. Before the material can be sluiced to the MVSTs, it must meet the requirements of WM-LWS-WAC, Waste Acceptance Criteria for Liquid Low-Level Waste System, Process Waste Treatment Complex-Building 3544, and Process Waste Treatment Complex-Building 3608, which contains requirements for ratios of ... continued below

Description

The Environmental Management Program at Oak Ridge National Laboratory (ORNL) is managing a project to remove the contents of the Old Hydrofracture (OHF) Tanks, located in Melton Valley. CDM Federal is responsible for sluicing the sludge and supernate from the OHF Tanks and transferring the slurry into the Melton Valley Storage Tanks (MVSTs), ORNL`s active liquid low-level waste system. Before the material can be sluiced to the MVSTs, it must meet the requirements of WM-LWS-WAC, Waste Acceptance Criteria for Liquid Low-Level Waste System, Process Waste Treatment Complex-Building 3544, and Process Waste Treatment Complex-Building 3608, which contains requirements for ratios of fissile to nonfissionable isotopes. Because the sludge and supernate contain uranium with increased ratios of U-233 and U-235 to U-238, depleted uranium must be added to the tanks to dilute the isotopic ratio of the contents before they can be sluiced. This work plan describes the denaturing activities, namely adding depleted uranyl nitrate solution, to be performed to ensure that the material meets requirements. Personnel from the ORNL Chemical Technology Division are responsible for the denaturing activity described in this work plan.
