Workers with the Oak Ridge Office of Environmental Management (OREM) and its contractor UCOR have finished installing the first of three large sludge-settling tanks for the Mercury Treatment Facility at the site’s Y-12 National Security Complex. The tanks, each of which will be 38 feet tall and 15 feet wide with a capacity of 36,000 gallons, provide a visible sign of ongoing progress on the facility where much of the construction has so far been below ground.

The Department of Energy’s Office of Environmental Management announced yesterday that waste processing operations have resumed at the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory Site. The resumption of operations follows the completion of two maintenance campaigns at the radioactive liquid waste treatment facility.

The Pennsylvania Department of Environmental Protection (DEP) expressed its confidence in the decommissioning work taking place at the damaged Three Mile Island Unit 2 during a recent meeting of the TMI-2 Community Advisory Panel (CAP). “We cannot be more pleased with the progress being made,” said Dwight Shearer, director of the DEP, during the meeting, held on September 13 in Middleton, Pa.
Hanford workers recently transferred three containers of nonradioactive test glass from the site’s WTP to the nearby Integrated Disposal Facility. (Photos: DOE)
According to the Department of Energy’s Office of Environmental Management, two contractors at its Hanford Site in Washington state have finished a first-time relay of test glass as the site prepares to vitrify—or immobilize in glass—millions of gallons of radioactive and chemical waste from its large underground tanks.

The International Atomic Energy Agency has found that Japan’s planned approach for recycling and disposing of soil and radioactive waste from decontamination activities after the 2011 Fukushima Daiichi nuclear accident is consistent with the agency’s safety standards.

The Energy Communities Alliance (ECA), which advocates for communities adjacent to or impacted by Department of Energy sites, is asking the department to conduct an independent analysis evaluating the impacts of delaying the implementation of its statutory interpretation of high-level radioactive waste, which holds that some waste from the reprocessing of spent nuclear fuel may be classified as non-HLW.
SRS liquid waste contractor Savannah River Mission Completion will use drones equipped with cameras to inspect the cleaning status of waste tanks at the site. (Photo: DOE)
The Department of Energy’s Office of Environmental Management will begin using drones for the first time to internally inspect radioactive liquid waste tanks at the department’s Savannah River Site in South Carolina. Inspections were previously done using magnetic wall-crawling robots.

Finland’s waste management organization Posiva announced that it has begun a trial run of placing spent fuel canisters in the Onkalo geologic repository, which is located near the Olkiluoto nuclear power plant in southwestern Finland. No spent fuel will be disposed of during the trial run, which is expected to last several months.

Crews at the Department of Energy’s Idaho National Laboratory Site recently completed work to transfer baskets of spent nuclear fuel ahead of a September 30 deadline.
This series of photos shows the grouting of the K West Reactor spent fuel storage basin. Workers removed nearly 1 million gallons of contaminated water before filling the 16-foot-deep basin with about 6,500 cubic yards of grout—enough to fill two Olympic-size swimming pools. (Images: DOE)
Workers at the Department of Energy’s Hanford Site in Washington state recently finished filling the last large concrete basin at the K Reactor Area with cement-like grout. The basin stored reactor fuel rods from historic plutonium production in the 1950s.

The Nuclear Regulatory Commission noted two low-level regulatory violations during a recent inspection of the San Onofre Nuclear Generating Station, which is currently undergoing decommissioning in Southern California. The violations involved the shipment of two reactor pressurizers from San Onofre to EnergySolutions’ disposal facility in Clive, Utah.

A collaboration between Savannah River Nuclear Solutions (SRNS) and Savannah River National Laboratory (SRNL) is making progress toward processing non-aluminum spent nuclear fuel (NASNF) as part of the site’s accelerated basin de-inventory mission. SRNL is the managing and operating contractor at the Department of Energy’s Savannah River Site in South Carolina.
