The U.S. Department of Energy has recently awarded a $45 billion contract to a consortium for the cleanup and treatment of toxic wastes at the Hanford Nuclear Reservation.

This contract will involve environmental cleanup and the treatment of millions of gallons of waste stored in tanks at the Hanford site.

Background and Site Overview

The Hanford Nuclear Reservation, located near the Tri-Cities in southeast Washington state, consists of 150 to 175 underground storage tanks holding approximately 56 million gallons of radioactive and toxic chemical waste.

Many of these tanks are aging and at risk of leakage, prompting efforts to transfer the contaminants to more secure double-walled tanks for further treatment.

Contract Details and Cleanup Activities

The awarded federal contract requires the newly formed company, Hanford Tank Waste Operations and Closure LLC (H2C), to operate tank farm facilities, design and construct waste-receiving facilities, and manage the Waste Treatment and Immobilization Plant.

This plant, known as the Vit Plant, will use extreme heat to convert the waste into a glasslike, noncontaminating material for permanent disposal.

Challenges and Recommendations

Cleanup activities at the Hanford site began in 1989 and are expected to take decades to complete.

While the vitrification process is a key component of the cleanup efforts, alternative approaches like immobilizing low-activity waste in a cement-like mixture called grout have been suggested.

These approaches could help reduce risks posed by leaking tanks, expedite treatment, and potentially save billions of dollars in cleanup costs.
