A company that Microsoft co-founder Bill Gates helped launch in 2006 is working with a federal cleanup contractor in Oak Ridge to extract rare isotopes from nuclear materials for cancer treatment research.

The project will significantly increase the number of cancer treatment doses available each year, federal officials and company executives said Friday. It will help remove highly enriched fissile nuclear material from Oak Ridge National Laboratory and save taxpayers an estimated $90 million, the officials and executives said. And it will recycle an isotope that would otherwise be “irretrievably lost” as the nuclear material, uranium-233, is converted into a disposal-ready form.

The U.S. Department of Energy, Isotek Systems LLC, and TerraPower celebrated with an announcement of the project in Oak Ridge on Friday morning.

TerraPower, which is based in Bellevue, Washington, where Gates is chairman, is particularly interested in actinium-225. That isotope can be extracted from thorium-229. The thorium will be removed from the fissile material, the uranium-233 stored at ORNL, by the federal cleanup contractor, Isotek.

The unique agreement, a public-private partnership, is expected to allow TerraPower the ability to make 100 times more actinium-225-based cancer treatment doses per year than the 4,000 doses that are currently available worldwide. TerraPower could first offer actinium-225 in late 2020, company executives said.

Workers are making significant progress removing asbestos and other hazardous waste from the Biology Complex at the Y-12 National Security Complex in a deactivation project that’s more than 60 percent complete, the U.S. Department of Energy said this week.

The work prepares the Biology Complex for demolition, possibly next year. The Biology Complex was originally built to recover uranium from process streams. It was later used for DOE’s research on the genetic effects of radiation from the late 1940s. When they operated, the facilities once had more people with doctorates than anywhere in the world, according to DOE.

Asbestos abatement teams from UCOR are working inside the six-story 9207 Facility and the three-story 9210 Facility. The first building is 256,600 square feet, and the second is 64,700 square feet.

“This project paves the way for EM (Environmental Management) to begin demolishing remaining buildings that comprise the Biology Complex next year,” the U.S. Department of Energy Office of Environmental Management said in an “EM Update” newsletter on Tuesday.

The largest and most visible buildings remaining at the East Tennessee Technology Park are being removed.

Demolition is under way on the Centrifuge Complex, according to the “EM Update” newsletter published last week by the U.S. Department of Energy Office of Environmental Management.

The demolition work is part of the project to finish cleanup at ETTP, the former K-25 site in west Oak Ridge, by the end of 2020. One of the three main sites in Oak Ridge, K-25 was built as part of the Manhattan Project, the top-secret federal program to build atomic weapons during World War II. The site continued to enrich uranium for nuclear weapons and commercial nuclear power plants through the Cold War. Its operations ended in the mid-1980s, and the site is now being converted into a private industrial park.

The Centrifuge Complex has more than 235,000 square feet, and sections of it reach heights of 180 feet. It was built in stages to develop and test centrifuge uranium enrichment technology, the “EM Update” said. The last of these facilities ceased operation in the mid-1980s.

Workers have begun processing a powder form of uranium-233 a year ahead of schedule as part of a larger environmental management, or cleanup, project to process and dispose of the remaining inventory of the nuclear material stored at Oak Ridge National Laboratory.

It’s the highest priority cleanup project at ORNL, a U.S. Department of Energy laboratory.

Isotek is the contractor responsible for processing and disposing of the uranium-233 inventory at ORNL. The work eliminates the need to use Building 3019, which is the oldest operating nuclear facility in the world, for storage of the material, according to DOE’s Oak Ridge Office of Environmental Management, or OREM.

In the 1970s and 1980s, nuclear facilities sent liquid uranium-233 to ORNL, and the site converted it into an oxide form, known as Oak Ridge Oxide, which is more stable for storage, OREM said in an “EM Update” newsletter published Tuesday. Some of the material was shipped to facilities for use as fuel in reactors. However, most of it was stored at ORNL until workers were able to dispose of it.

The U.S. Department of Energy said its Office of Environmental Management and its contractors know the importance of training to ensure safety.

Recently, that training helped save a life in an unlikely place, DOE said in a story published Tuesday.

While eating lunch at a local restaurant, Eric Glenn, a radiological control technician at Isotek, noticed a man choking on his sandwich.

“I just heard a man coughing and he did the choking sign, so I ran over and gave him the Heimlich maneuver six or seven times,” Glenn said.

Work began in June to build the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow the U.S. Department of Energy to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for nuclear weapons during the Cold War in the 1950s and 1960s. The facility is expected to help reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced in December that it had awarded a $91 million contract to build the Mercury Treatment Facility. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

A groundbreaking was held at the site in November 2017, and site preparations were completed by December 2018.

The U.S. Department of Energy is requesting more time to complete projects to commemorate the historic contributions of the former K-25 site in west Oak Ridge.

Built during World War II, the K-25 site helped enrich uranium for the first atomic bomb used in wartime as part of the top-secret Manhattan Project. The plant continued to enrich uranium for nuclear weapons and commercial nuclear power plants after the war, and those who have worked at the site have said it helped win the Cold War.

The history of the site will be honored by preserving the concrete slab of the former K-25 Building, building a Viewing Tower and replica Equipment Building on the south side of the building site, and opening a K-25 History Center on the second floor of the adjacent Oak Ridge Fire Station Number 4.

A historical interpretation agreement was signed in August 2012. But it expires this August. And the roughly $20 million worth of projects won’t be complete by then.

DOE is making “good progress,” but “the reality is we need a little more time,” said Dave Adler, acting deputy manager for DOE’s Oak Ridge Office of Environmental Management. Adler and Steve Cooke, K-25 preservation coordinator for DOE, briefly discussed the proposed amendment to the agreement during a Tuesday evening work session with the Oak Ridge City Council.

The Oak Ridge City Council and U.S. Department of Energy will discuss a proposed amendment to a historical interpretation agreement on Tuesday evening.

The agenda for the non-voting Council work session does not give the purpose of the proposed amendment or say what it might do.

But it appears that the proposed amendment could be related to historical interpretation at the former K-25 site in west Oak Ridge because one of the DOE representatives scheduled to talk to Council is Steve Cooke, K-25 preservation coordinator for the U.S. Department of Energy. Also scheduled to talk to Council is Dave Adler, acting deputy manager for DOE’s Oak Ridge Office of Environmental Management. [Read more…]

(For members) DOE could lease space to store elemental mercury

Image from “Final Long-Term Management and Storage of Elemental Mercury Supplemental Environmental Impact Statement” published by U.S. Department of Energy in September 2013.

The U.S. Department of Energy is considering whether to lease space to store elemental mercury from sites across the country.

The facility could store about 1,200 metric tons (1,300 tons) of elemental mercury. The waste has been generated at sites in the United States, mostly at gold mining operations, according to the DOE Office of Environmental Management.

The mercury that could be stored at the leased facility is separate from the 1,200 metric tons of mercury stored at the Y-12 National Security Complex in Oak Ridge. The Y-12 mercury, about 2.6 million pounds stored in seamless steel flasks, was acquired for lithium-6 isotope separation operations for thermonuclear weapons.

Cleanup crews started a $4.7 million project this month to reduce maintenance and operations costs at the Molten Salt Reactor Experiment, which was shut down 50 years ago at Oak Ridge National Laboratory.

The project is expected to save nearly $25 million in costs, the U.S. Department of Energy Office of Environmental Management said in an “EM Update” published Tuesday.

The cost-reduction project will relocate employees stationed at the decades-old facility. Personnel currently housed in the building will move to other site locations to help with other projects, the “EM Update” said.

The project is expected to enhance the facility’s electrical distribution, sump pump, fire suppression, and monitoring systems.

“Although it was shut down 50 years ago, certain systems within the reactor building have continued to operate to keep the facility safe and stable until it can be demolished,” said the “EM Update,” with the Oak Ridge story contributed by Mike Butler. [Read more…]
