The Department of Energy has announced that the Hanford Site’s Waste Treatment and Immobilization Plant (WTP) has reached a commissioning milestone, producing more than 20 stainless steel containers of immobilized low-activity radioactive waste.

Hanford conducts test of tank waste treatment support facilities

Work crews at the Department of Energy's Hanford Site recently completed the first transfer of test water from the Waste Treatment and Immobilization Plant's Effluent Management Facility to the nearby Liquid Effluent Retention Facility (LERF). The transfer of 6,000 gallons was the first simulation of the process that will be used to treat secondary liquid waste from the plant’s Low-Activity Waste Facility during operations to treat tank waste.

“This is a tremendous accomplishment that culminates years of work by our team and alumni toward being ready for hot commissioning,” said Valerie McCain, project director and senior vice president for Bechtel National, Inc. “It’s an important step for the entire Hanford team and our collective mission of protecting the Columbia River and its shoreline communities.”

Bechtel National is a contractor of the DOE's Office of Environmental Management's Office of River Protection.

Waste transport system testing underway at Hanford

Startup engineers at the Hanford Site’s Waste Treatment and Immobilization Plant (WTP) have been performing mechanical equipment testing on the two units that make up the “bogie,” or cart transport rail system, in the lower level of the Low-Activity Waste (LAW) facility.

During future plant operations, containers will be filled with vitrified radioactive and chemical waste and placed on the bogie transport rail that leads to the facility’s finishing line area before the containers are moved to storage.

To date, all 94 systems in the LAW facility have been turned over to startup, and 38 of those have been handed over for commissioning, according to the DOE on January 26.
