Following a second planned maintenance outage, the Tank-Side Cesium Removal (TSCR) system at the Hanford Site in Washington state has resumed processing liquid tank waste, the Department of Energy’s Office of Environmental Management (EM) announced on March 14.

According to EM, its Office of River Protection (ORP) and contractor Washington River Protection Solutions processed more than 25,000 gallons of waste during the previous week and has treated a total of 406,000 gallons of radioactive liquid waste since TSCR began operations early last year.

A key component in Hanford’s Direct-Feed Low-Activity Waste program for treating tank waste, TSCR removes radioactive cesium and solids from tank waste and delivers low-activity waste to a nearby million-gallon tank, where it is staged until it can be fed to the Waste Treatment and Immobilization Plant for vitrification.

Outage improvements: During outages, workers change out filter columns that remove radioactive solids during waste processing, perform maintenance, and apply lessons learned from operations. According to EM, many improvements to the treatment system during outages over the past year came from recommendations made by workers and contractor and federal staff on the project team.

Hanford’s waste vitrification operations are unlikely to start by the Department of Energy’s year-end goal, said Brian Vance, manager of the DOE’s Office of River Protection and Richland Operations Office for the Hanford Site in Washington state. The DOE is working to meet its obligations to begin processing Hanford’s low-level radioactive tank waste as part of its Direct-Feed Low-Activity Waste (DFLAW) program.

“The probability for 2023 is very low,” Vance said, regarding the department’s plan to begin vitrifying the tank waste. Vance made his remarks during a panel session of the 2023 Waste Management Symposia in Phoenix, Ariz., on February 28.

Idaho’s IWTU resumes heat-up following repairs

February 2, 2023, 7:01AMRadwaste SolutionsJohn Fabian

The Department of Energy’s Office of Environmental Management (EM) said that heat-up of Idaho’s Integrated Waste Treatment Unit (IWTU) resumed in January. Crews began heating the IWTU in December in preparation of radiological operations, but the facility was shut down 10 days later after operators noticed a small leak of nonradioactive material inside one of the unit’s processing cells.

Located at the DOE’s Idaho National Laboratory Site, the IWTU is intended to treat Idaho’s 900,000 gallons of sodium-bearing liquid waste, converting it to a solid using a steam-reforming process.

After repairs were made to the IWTU equipment responsible for the leak, crews removed a partial obstruction that was in a line into the carbon reduction reformer, a key treatment vessel in the steam-reforming process, EM said.

Ten days after beginning a heat-up process to prepare for radiological operations at Idaho’s Integrated Waste Treatment Unit (IWTU), operators noticed a small leak of nonradioactive, nonhazardous solids in a cell, resulting in the facility’s shutdown in late December, the Department of Energy announced on January 10.

The Department of Energy’s Office of Environmental Management (EM) said that the Integrated Waste Treatment Unit (IWTU), the radioactive liquid waste treatment facility at the Idaho National Laboratory Site, began its final heat-up in December prior to initiating radiological operations, planned for early this year.

IWTU crews were to follow a prescribed incremental process as the facility transitions from simulant to sodium-bearing waste (SBW), according to EM.

Employees have begun emplacing defense-related transuranic (TRU) waste in Panel 8 of the Waste Isolation Pilot Plant (WIPP) in New Mexico, the Department of Energy’s Office of Environmental Management (EM) announced in November. TRU waste is permanently disposed of at WIPP in rooms mined in a Permian salt bed 2,150 feet below the surface.
