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.

About half of uranium-233 waste shipped from Building 3019 at ORNL

About half of the uranium-233 waste stored in Building 3019 at Oak Ridge National Laboratory has been shipped to a disposal facility in Nevada.

The shipments were completed in August, said Jay Mullis, manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management.

But federal officials were only recently able to announce the end of the shipments of the waste from the Consolidated Edison Uranium Solidification Program, or CEUSP. The waste contained radioisotopes of uranium from a 1960s research and development test of thorium and uranium reactor fuel at the Consolidated Edison Indian Point-1 reactor in New York. The test was sponsored by the Atomic Energy Commission, a predecessor to the U.S. Department of Energy.

The shipments were completed 10 months ahead of schedule, Mullis told the Oak Ridge Site Specific Advisory Board on Wednesday, November 8. The CEUSP waste had been treated and turned into a ceramic matrix. It was shipped from Building 3019 at ORNL, where it had been stored, to the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas. DOE started shipping the waste materials to the Nevada National Security Site in May 2015.

DOE disposing of uranium-233 waste stored at ORNL

ORNL CEUSP Waste Shipping

They haven’t agreed on a final budget number, but the Trump administration and the U.S. House and Senate have proposed spending between about $33 million and $52 million in the next fiscal year to continue disposing of uranium-233 waste materials that are stored at Oak Ridge National Laboratory in a building that is the oldest continuously operating nuclear facility in the U.S. Department of Energy complex.

The uranium-233, or U-233, waste is now stored in secure vaults in Building 3019, which was built in the 1940s at ORNL. Removing the waste could allow ORNL to relax its overall security posture, which will reduce costs, eliminate nuclear safety issues, and make the campus more conducive to collaborative science, according to a U.S. Senate Appropriations Committee report published in July.

Some of the waste is from a 1960s research and development test in New York, and it is being shipped to the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas. In interviews this summer, DOE officials in Oak Ridge declined to discuss the amount of that waste that has been shipped to Nevada or to say how long the shipments might continue. But they are making progress, said Jay Mullis, acting manager of DOE’s Oak Ridge Office of Environmental Management.

Once all of those materials are shipped, the remaining U-233 at ORNL will be treated in “hot cell” facilities across the street from Building 3019, at Building 2026. The DOE’s Oak Ridge Office of Environmental Management owns both buildings.

Mullis said there is other U-233 waste stored in Building 3019, including from glovebox research at ORNL, from reactor plates, and from conglomerate materials. [Read more…]

DOE: Pavement collapse at ORNL a significant distance from U-233 storage area

A pavement collapse at Oak Ridge National Laboratory in early June was a significant distance from an area where uranium-233 is stored at Building 3019, the U.S. Department of Energy said Monday.

The collapse of about 36 square feet of pavement was near Building 3019B, which is an inactive facility, the DOE Oak Ridge Office of Environmental Management said.

The hot cells in the facility were not affected, and they do not contain radioactive material, DOE said.

“There were no immediate safety hazards to personnel, but as a precaution, the area was barricaded until crews made repairs,” DOE said.

Uranium-233, or U-233, is a fissionable material, and Building 3019 area is a secure and controlled area. The pavement collapse was reported by the Defense Nuclear Facilities Safety Board on June 19. [Read more…]
