The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.

ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.

Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

Construction of a backup load-in station has been completed at the Hanford Site’s Effluent Treatment Facility (ETF) in Washington state.

“We broke ground on the backup facility about a year ago,” said Rob Wood, project manager for Washington River Protection Solutions, the Department of Energy’s tank operations contractor at the site. “I am proud of the team for completing this portion of the load-in expansion project and doing it safely. In phase two, expansion of the main load-in station will prepare us for 24/7 operations on the Hanford Site.”

The Department of Energy's Office of River Protection and the Richland Operations Office hosted a roundtable discussion recently with tribal nations located near the Hanford Site to review the Department’s tribal government policy—Order 144.1, the American Indian and Alaska Native Tribal Government Policy—and discuss opportunities for strengthening tribal consultation.

The Office of River Protection is within the purview of the DOE's Office of Environmental Management (EM). The Hanford Site, in eastern Washington state, is a 586-square-mile site that was used as a nuclear production complex during the World War II era.
