Hanford steps up waste treatment

RICHLAND – The U.S. Department of Energy announced Wednesday workers have begun the first large-scale treatment of radioactive and chemical waste from large underground tanks at the Hanford Site. This marks completion of the first of an ambitious slate of 2022 priorities set by the DOE Office of Environmental Management.

The newly operational tank side cesium removal system removes radioactive cesium and solids from tank waste.  The treated waste will be fed directly to the nearby Waste Treatment and Immobilization Plant for vitrification, or immobilization in glass, when the plant comes online next year. 

The cesium removal system is a key part of the site’s direct feed low activity waste program, an assembly of several highly interdependent projects and infrastructure that will operate together to vitrify and safely dispose of millions of gallons of low-activity tank waste once operational.

Hanford tank operations contractor Washington River Protection Solutions, working with environmental management staff, other site contractors and regulatory agencies; built, installed, and tested the cesium removal system next to large underground storage tanks. Those tanks, called the AP tank farm, are located near the center of the Hanford Site, which is less than a quarter mile from the vitrification plant.

John Eschenberg, WRPS president and CEO, said the launch of the TSCR system operations was nearly three years in the making.

“I’m extremely proud of our team, the dedicated workforce who delivered this project on time and on budget during some challenging times over the last 18 months,” Eschenberg said.

The Hanford Site is home to approximately 56 million gallons of radioactive tank waste stored in 177 underground tanks, representing one of DOE’s largest environmental risks and most complex challenges.  The tank waste is a result of nearly five decades of plutonium production.
