Idaho Waste Treatment Facility Surpasses State Milestones in Strong Five-Month Run

A radioactive liquid waste treatment facility at the Idaho National Laboratory Site recently completed its most successful run to date by treating more than 211,000 gallons of material and meeting two critical milestones with the state of Idaho.

The Integrated Waste Treatment Unit (IWTU) has since entered an outage to conduct routine maintenance following the five-month waste treatment run. Following the outage, the IWTU will return to normal radiological operations.

To date, the IWTU has converted more than 279,000 gallons of waste. The facility was constructed to treat approximately 900,000 gallons of radioactive liquid waste from three nearby underground storage tanks to convert it to a safer, granulated waste form.

Test Proves Robot Successful in Supporting Idaho Waste Retrieval Mission

A robot central to innovative methods Idaho Cleanup Project crews are developing to retrieve calcine, a granular solid waste, has successfully demonstrated its proficiency.

The team recently launched a new technology and equipment test at the Idaho National Laboratory (INL) Site to prove the capability of remote-handled robotics to properly weld access points in the Calcined Solids Storage Facilities, where 4,400 cubic meters of calcine waste is stored. The robot passed the test.

All calcine waste must be removed from the state for permanent disposal under an agreement with the State of Idaho. The U.S. Department of Energy (DOE) had converted liquid, high-level radioactive waste into calcine, which is similar in consistency to sand, until those operations ended in 2000. The waste was created during historic spent nuclear fuel reprocessing runs at the Idaho Nuclear Technology and Engineering Center.
