The Department of Energy is asking for feedback on a new report analyzing potential options for preparing high-level radioactive waste for vitrification at the department’s Hanford Site near Richland, Wash. Vitrification is the process of treating radioactive waste by immobilizing it in glass.

The report, Waste Treatment and Immobilization Plant High-Level Waste Treatment: Analysis of Alternatives, was commissioned in response to a 2018 determination by the U.S. Army Corps of Engineers that it was unlikely the DOE would meet its mandated deadlines for treating Hanford’s tank waste.

DOE increases consent-based siting FOA to $26 million

January 23, 2023, 7:01AMRadwaste Solutions

The Department of Energy has increased the funding level for its community engagement on consent-based siting funding opportunity announcement (FOA) from $16 million to $26 million. The DOE first announced it was making funding available to communities interested in learning more about consent-based siting, management of spent nuclear fuel, and interim storage facility siting considerations last September. The FOA follows the DOE’s recent update to its consent-based process for siting an interim storage facility for SNF.

Cell leak delays startup of Idaho’s IWTU

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.

New members appointed to nuclear waste board

What about the waste?

It’s always the first question asked. So, what is your approach? You have options.

You could go the “Yucca Mountain is the law of the land” route. But you’ll soon run into an immutable political truth. Nevada’s early presidential caucuses make it highly unlikely that any candidate would ever take a favorable position on Yucca unless it enjoyed commensurate support in the state. Not convinced? Nevada Gov. Stephen Sisolak signed a bill in August that replaces their closed caucus system with a primary during the first week in February, thereby putting the state in competition with Iowa and New Hampshire to be the “first primary” of the 2024 election. Face it: While you weren’t looking, Nevada secured its consent rights over Yucca Mountain; it’s just written in a different part of the law.

You could also double down on reprocessing/recycling and argue that we need some sort of Manhattan Project. But that requires convincing Congress that it’s a good idea for the government to build large, first-of-a-kind, multibillion-dollar fuel cycle facilities, the economics of which will be based on the estimated price of uranium (or thorium?) some number of decades from now. Good luck with that. As much as a grand solution to the fuel cycle may appeal to our engineering instincts, the funding simply isn’t there—there are no checks left in Washington’s checkbook.

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.

Two reports agree: Diverse advanced reactor fuel cycles can succeed

November 23, 2022, 6:39AMNuclear News

Advanced reactors and small modular reactors with strikingly different coolants and sizes offer an array of different benefits, but when it comes to fuel cycle issues, including spent fuel and waste, they have a lot in common with conventional light water reactors. Two reports released within the last week—a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus committee report two years in the making and a Department of Energy study released by Argonne National Laboratory—address the timely topic of advanced reactor fuel cycle issues. While the NASEM committee ventured to define research and infrastructure needs to support the entire nuclear power fuel cycle, inclusive of new technologies, for decades to come, the DOE report compares the front- and back-end fuel cycle metrics of three reactor designs (from NuScale Power, TerraPower, and X-energy) that have been selected for DOE cost-share–funded demonstrations within this decade. Together, these reports provide assurance that the fuel cycle needs of a fleet of new reactors can be met and point to near-term research and planning needs.

Contractor employees at the Department of Energy’s Savannah River Site in South Carolina recently exceeded their plutonium downblending goal for 2022 ahead of schedule as part of the ongoing activities to remove Pu from the state, the DOE’s Office of Environmental Management (EM) announced.

“Abnormal condition” pauses Hanford melter heat-up

Heating of the first waste vitrification melter at the Department of Energy’s Hanford Site was paused after operators identified an “abnormal condition with the startup heater power supplies,” the DOE’s Office of River Protection (ORP) said. Heat-up of the 300-ton melter, which will be used to vitrify Hanford’s low-level radioactive tank waste, was initiated on October 8.

Crews at the Department of Energy’s Hanford Site, near Richland, Wash., have begun heating up the first of two 300-ton melters that will be used to vitrify mixed low-level radioactive and chemical tank waste. According to the DOE’s Office of Environmental Management (EM), initiating and completing the heating of the melter is a critical step to commissioning Hanford’s Waste Treatment and Immobilization Plant (WTP), which will treat and stabilize the site’s 56 million gallons of tank waste by immobilizing it in glass through the vitrification process.

DOE releases 5-year Hanford cleanup plan
