【 摘 要 】

The High Level Waste Tank Farms store and process high-level liquid wastes from a number of sources including F- and H-Canyons and a recycle stream from the Defense Waste Processing Facility. The waste is relatively dilute as received and is concentrated in one of several evaporators to minimize the space required to store the waste. The concentrated waste is transferred to one of several concentrate receipt tanks for storage, currently Tank 38H. Recently, the 2H Evaporator was shut down due to crystallization of aluminum silicates in the evaporator and the co-precipitation of enriched uranium with the aluminum silicate. This raised a concern about the criticality safety of the evaporator. To alleviate the space problem, it has been suggested that material from certain tanks, including Tank 38H may be dissolved, possibly filtered, and then transferred to the Saltstone Facility for disposal.
