Workers at the Hanford Site have nearly completed excavation at a former waste site near the Columbia River. June 17, 2025.

Hanford crews are preparing for the site’s first-ever transfer of radioactive waste from one of its large underground tanks to the Waste Treatment and Immobilization Plant. June 17, 2025.

By installing the last piece of pipe, Hanford Site workers have completed the final connection between underground tanks storing radioactive waste and the waste treatment plant that will begin solidifying it in glass later this year. June 10, 2025

A new method has received state approval for use at the Hanford Site's 222-S Laboratory, improving how experts analyze tank waste and providing more precise data to support safe, efficient cleanup. June 10, 2025

A new artificial intelligence tool is helping workers at the Hanford Site save time, work smarter and keep sensitive data secure. June 3, 2025
The U.S. Department of Energy Office of Environmental Management is advancing the Hanford Site tank waste mission by introducing key chemicals into the Waste Treatment and Immobilization Plant as part of ongoing cold commissioning testing.

Contractors at the Hanford Site have teamed up to launch a new ordering system that speeds up supply requests while improving security and efficiency.

Crews recently installed a new treatment tower at the Hanford Site, giving a major boost to a groundwater cleanup effort that processes billions of gallons of contaminated water each year.

The 222-S Laboratory plays an important role in analyzing radioactive tank waste at the Hanford Site — so when crews needed to shut down the facility’s power for a full week to complete infrastructure upgrades, timing and precision were everything.

Hanford’s Test Bed Initiative could pave the way for future tank waste treatment options
