Operations resumed at the Hanford Site after storage Tank AP-106 gained sufficient capacity to accept additional processed material. The system had been idle for six months because the receiving tank was too full to handle more low-level waste. Site managers noted that the bottleneck supports proposals for a dual glass and grout disposal strategy to prevent future operational delays.

Earlier this week, the Tank-Side Cesium Removal (TSCR) system at the Department of Energy's Hanford Site near Richland, Wash., returned to service following a pause in operation that began on February 25.

The system, which produces low-level waste material by filtering radioactive cesium and solid materials from liquid waste, normally is available for a new treatment cycle about two weeks after a previous batch of waste has been processed. However, operators at Hanford decided against restarting the system in March, because Tank AP-106, which has been the storage receptacle for TSCR-processed material, was "too full" at the time to accept more LLW, according to the DOE.
