When it comes to managing nuclear waste, technology is transforming the way some of the most problematic waste is handled. The idea to transform nuclear waste into glass was developed back in the 1970s as a way to lock away the waste’s radioactive elements and prevent them from escaping. For more than 40 years, vitrification has been used for the immobilization of high-level radioactive waste in many countries around the world, including the United States.

Some of Hanford’s tank waste to be disposed of off-site as LLW

As preparations continue for immobilizing millions of gallons of low-activity tank waste at the Hanford Site in Washington state through vitrification, the Department of Energy has issued two key decisions for the handling and disposing of vitrified low-activity waste (LAW) and associated secondary wastes.

The DOE recently completed startup testing on the uninterruptable electrical power system for Hanford’s Low-Activity Waste Facility.

Department of Energy workers recently finished startup testing of a battery-powered backup electrical system for the Low-Activity Waste (LAW) Facility at the Hanford Site near Richland, Wash. According to the DOE’s Office of Environmental Management (EM), the uninterruptable electrical power system is vital to safeguarding the facility, part of Hanford’s Waste Treatment and Immobilization Plant, in the unlikely event of a temporary power loss to the plant.

As the workers at Hanford’s Waste Treatment and Immobilization Plant (WTP) move closer to starting up the first of two melters inside the plant’s Low-Activity Waste (LAW) Facility, plant contractor Bechtel National has launched the Journey to Melter Heatup website that explains the WTP commissioning process, including critical activities such as the loss-of-power test and the melter heatup process.

Crews make progress on Hanford tank farm improvements

Work crews at the Department of Energy's Hanford Site recently completed removal and staging of 52 large concrete covers used to shield hoses for transferring radioactive waste between waste tanks in Hanford’s AY and AP farms. (Tank farms are groups of tanks.) The covers, known as “barns,” are being staged as part of an infrastructure improvement project until they can be used in the building of a hose system that will transfer waste from Hanford's A farm to the AP farm.
