Waste Management

Workers at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, have begun removing the first three of 18 temporary startup heaters, the Department of Energy announced on September 12. The startup heaters were used to raise the first of two 300-ton glass melters in the plant’s Low-Activity Waste Facility to its operating temperature of 2,100°F.

The Department of Energy has released the first request for information (RFI) related to the department’s Cleanup to Clean Energy initiative, which aims to repurpose certain DOE-owned lands, portions of which were previously used in the nation’s nuclear weapons program, into sites for clean energy generation.

The Minnesota Public Utilities Commission (PUC) has approved Xcel Energy’s request for a certificate of need to expand spent fuel storage at the utility’s Monticello nuclear power plant.

The additional storage, according to the PUC, requires installation of a second concrete support pad and modular concrete storage system designed to hold 14 additional steel canisters.

Xcel had requested increased outdoor storage to accommodate its plan to extend Monticello’s operational life by 10 years, to 2040.

Deep Isolation announced this week that it has received funding from the Department of Energy to test a range of deep borehole disposal canisters at a test facility in Cameron, Texas, managed by the nonprofit Deep Borehole Demonstration Center.

The three-judge panel of the New Orleans–based 5^th U.S. Circuit Court of Appeals last week vacated Interim Storage Partners’ (ISP) license for a consolidated interim storage facility for commercial spent nuclear fuel in Andrews County, Texas.

National, state, and local leaders joined the Department of Energy’s Oak Ridge Office of Environmental Management (OREM) and its lead cleanup contractor, United Cleanup Oak Ridge (UCOR), earlier this month to celebrate the groundbreaking for a new on-site disposal facility at the Oak Ridge Reservation in Tennessee.

Washington, D.C. – The American Nuclear Society (ANS) supports the start of Japan’s controlled release of re-treated, diluted tritium wastewater into the sea from the Fukushima Daiichi Nuclear Power Plant (NPP), which sustained damage in the aftermath of a 2011 earthquake and tsunami.

The New Mexico Environment Department (NMED) released the proposed final permit for the Waste Isolation Pilot Plant renewal process on August 15. The NMED also announced a public hybrid meeting scheduled for September 22, where the public will have the opportunity to ask questions about the proposed final permit.

After decades of planning and weeks of preparation and checks, the first batch of legacy waste has been retrieved from the Pile Fuel Cladding Silo at the Sellafield nuclear site in West Cumbria, England. According to Sellafield Ltd., the site license company, a state-of-the-art robotic arm was used to reach into the silo and, for the first time, remove and repackage the waste for longer-term storage.

These retrievals mark a significant achievement in progress toward the cleanup and decommissioning of one of the most hazardous buildings on the site, according to Sellafield Ltd., which made the announcement on August 16.

The Department of Energy’s Savannah River Site in South Carolina will begin a leak tightness test on what it called “the fourth megavolume saltstone disposal unit (SDU)” at the site.

The International Atomic Energy Agency is launching a new Coordinated Research Project (CRP) to increase international knowledge and drive progress toward testing deep borehole disposal for intermediate- and high-level radioactive waste.

To expand interim storage of vitrified high-level radioactive waste at the Savannah River Site, the Department of Energy’s Office of Environmental Management and its liquid waste contractor Savannah River Mission Completion (SRMC) have double stacked 2,000 canisters in one of the site's two glass waste storage buildings (GWSB). GWSB 1 consists of a below-grade, seismically qualified concrete storage location containing support frames for the vertical storage of 2,262 10-foot-tall canisters.

The Department of Energy’s Office of Environmental Management announced that the first batches of glass-forming beads, called frit, were poured last week into a melter at the Hanford Site’s Waste Treatment and Immobilization Plant (WTP), also known as the Vit Plant. The melter, which has been heated to 2,100ºF, will be used to immobilize Hanford’s radioactive and chemical tank waste, turning it into a stable glass form through vitrification.

Sellafield Ltd., a subsidiary of the U.K. government’s Nuclear Decommissioning Authority, announced that drone pilots have successfully completed two firsts in the use of unmanned aerial vehicles (UAV) at the Sellafield nuclear site in Cumbria, England.

According to the company, the flights, which accessed a Sellafield building with limited space using a light detection and ranging (lidar) sensor and a radiation dosimeter, are helping improve the safety of employees during the decommissioning of the site’s legacy buildings.

Mapping flight: First, an Elios 3 drone equipped with a lidar sensor was able to successfully collect data from a site building. The data will be processed to produce a 3D model of the area, which will help inform engineering decisions. According to Sellafield, the mapping flight marks a major milestone for the site’s UAV team, enabling unparalleled efficiency in mapping and 3D modeling.

More than 100 people from Savannah River National Laboratory and the Hanford Site participated recently in a workshop to share analytical knowledge focused on the cleanup of radioactive tank waste at Department of Energy sites.

The Department of Energy announced last week that Melter 1 at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, has hit its operational temperature of 2,100ºF. The DOE began heating Melter 1 in October 2022, but was soon forced to pause when abnormalities in the heaters’ power supply were encountered.

The Nuclear Waste Technical Review Board, which evaluates the Department of Energy’s activities on radioactive waste management, is holding a hybrid (in person and virtual) public meeting on August 30 to discuss the DOE’s consent-based process for siting one or more federal interim storage facilities for commercial spent nuclear fuel. The DOE’s research and development related to high-burnup SNF and advanced reactor waste disposal will also be discussed.

The Nuclear Regulatory Commission reported on July 27 that it has issued a license to Rare Element Resources Inc. for a proposed pilot project in Wyoming to demonstrate a proprietary process to extract rare earth elements from ore.

The Department of Energy is planning to ship contaminated process equipment from its Savannah River Site in South Carolina to Waste Control Specialists’ federal low-level radioactive waste facility in Andrews County, Texas.

The National Academies of Sciences, Engineering and Medicine (NASEM) recently held a public meeting to discuss its third and final report centered on the Department of Energy’s Office of Environmental Management’s tank waste cleanup mission at the Hanford Site in Washington state.
