RICHLAND, Wash. - Workers at the Hanford Site 's Waste Treatment and Immobilization Plant (WTP) finished installing a caustic scrubber, beating an interim milestone by nearly two weeks. The scrubber is a 19-ton piece of the offgas treatment system in the Low-Activity Waste (LAW) Facility. This system ensures exhaust from LAW meets air quality requirements. Other system components, including the thermal catalytic oxidizer and ammonia dilution skid, can be seen in the Hanford Vitrification Plant Virtual Tour. The LAW Facility is part of the Department's plan to start treating tank waste as soon as 2022. A phased approach to the plant allows startup, commissioning and early use of facilities that are complete or close to completion while EM’s Office of River Protection resolves technical issues associated with the Pretreatment and High-Level Waste Facilities.
