The Decommissioning of Portsmouth’s X-326

November 14, 2022, 3:00PMRadwaste SolutionsGuest Contributor

In the 1950s, the U.S. Department of Energy constructed the Portsmouth Gaseous Diffusion Plant in rural southern Ohio to enrich uranium, alongside two other federally owned and managed facilities in Oak Ridge, Tenn., and Paducah, Ky. The Cold War-era plant was built as a self-sufficient industrial city with more than 400 buildings and facilities centered around three massive gaseous diffusion process buildings that could enrich the level of the uranium-235 isotope for nuclear fuel in the defense and energy sectors.

In May 2019, Zahn’s Corner Middle School in Pike County, Ohio, located within four miles of the former Portsmouth Gaseous Diffusion Plant (PORTS), was closed after local officials reported enriched uranium and transuranic radionuclides were detected inside the school and at outside air monitors.

Now, Cincinnati’s WKRC Local 12, a news affiliate of Sinclair Broadcast Group, is reporting that a private house in Lucasville, Ohio, 10 miles from the PORTS site, has been contaminated with enriched uranium.

The Department of Energy’s Office of Environmental Management (EM) announced that construction of Hanford’s K East Reactor cocoon has been completed ahead of schedule and under budget. Cocooning of K East—enclosing it in a protective steel structure while the reactor’s radioactivity naturally decays—was one of EM’s key construction priorities for 2022.

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.

DOE awards $38 million to advance used fuel recycling

October 26, 2022, 6:38AMRadwaste Solutions

The Department of Energy is providing $38 million in funding for a dozen projects aimed at developing technologies to advance spent nuclear fuel reprocessing, reduce the volume of high-level waste requiring permanent disposal, and provide domestic advanced reactor fuel stocks. The projects are being led by universities, private companies, and national laboratories.

The Department of Energy and its environmental cleanup contractor United Cleanup Oak Ridge (UCOR) are poised to meet critical milestones as they continue to move to the next generation of cleanup at Oak Ridge National Laboratory in Tennessee. On ORNL’s main campus, crews on “Reactor Hill”—so named because of the four remaining reactor facilities on that hillside—and at the Experimental Gas-Cooled Reactor (EGCR) just east of the campus continue rigorous schedules as they enter a new phase of progress in the cleanup program.

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

October 11, 2022, 9:37AMRadwaste Solutions

By fiscal year 2027, Hanford’s Waste Treatment and Immobilization Plant (WTP) will ramp up toward producing 21 metric tons of low-level radioactive glass a day, according to the Department of Energy’s five-year plan for the site near Richland, Wash.

The plan, which was released on October 3 and opened for a 31-day public comment period, outlines what cleanup work will be initiated or completed at the Hanford Site during FYs 2023–2027.

Based on a review of U.S. Atomic Energy Commission (AEC) records and available data from numerous agencies, there are an estimated 4,225 mines across the country that provided uranium ore to the U.S. government for defense-related purposes between 1947 and 1970. To aid in the cleanup of these legacy uranium mines and establish a record of their locations and current conditions, the Defense-Related Uranium Mines (DRUM) program was established within the Department of Energy’s Office of Legacy Management (LM).
