About 600 experiments and roughly 500 users were affected by the nearly year-long shutdown of the High Flux Isotope Reactor at Oak Ridge National Laboratory, the lab said Thursday.

HFIR, which is used for research and isotope production, restarted October 29, 2019. It had been shut down since November 13, 2018, after an elevated radiation level was detected in the reactor’s primary cooling system.

Reactors users who had approved proposals when HFIR was shut down have been running those experiments since it restarted in the fall, according to a response to questions provided by ORNL spokesperson Morgan McCorkle on Thursday. The backlog is expected to be completed by the spring.

The shutdown did not affect the production of plutonium-238, but it did delay the production and distribution of some medical and industrial isotopes, the lab’s response said.

The U.S. Department of Energy is investigating fuel element performance in the High Flux Isotope Reactor, which is used for research and isotope production at Oak Ridge National Laboratory, after elevated radiation levels were found in the cooling system last year, possibly due to a pinhole leak.

The investigation of potential noncompliances with DOE nuclear safety program requirements was announced this month by the DOE Office of Enterprise Assessments’ Office of Enforcement. The office notified UT-Battelle LLC, ORNL’s managing and operating contractor, and BWXT Nuclear Operations Group Inc. of Lynchburg, Virginia, on December 5. BWXT manufactured components that were involved.

ORNL has said the slightly elevated reading in the primary cooling system was well below alarm levels, and there was no impact to the public, the environment, or workers, and the reactor was not damaged or compromised.

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.

The U.S. Department of Energy still has the two most powerful supercomputers in the world, including Summit at Oak Ridge National Laboratory, according to a semiannual list released Monday.

It’s the fourth time in the past two years that Summit, an IBM-built supercomputer, has been number one on the TOP500 list of of the world’s most powerful supercomputers.

The United States displaced China at the top of the list last year, in June. Two years ago, in November 2017, China had the top two systems in the world.

Summit debuted at number one in June 2018. That was the first time since 2012 that the United States had the most powerful supercomputer in the world. Summit retained the top spot in November 2018 and again in June 2019.

The Sierra supercomputer at Lawrence Livermore National Laboratory in Livermore, California, climbed to number two from number three in November 2018. It remained at number two on the June list and again on the list released Monday, meaning it’s been number two on three versions of the list in the past two years.

Summit and Sierra are both IBM-built supercomputers that use Power9 central processing units (CPUs) and NVIDIA Tesla V100 graphics processing units (GPUs).

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.

ORNL-Veterans Affairs collaboration targets veteran suicide epidemic

Submitted by Oak Ridge National Laboratory

More than 6,000 veterans died by suicide in 2016, and from 2005 to 2016, the rate of veteran suicides in the United States increased by more than 25 percent.

Suicide prevention is the highest priority for the U.S. Department of Veterans Affairs—so much so that in recent years, the VA has started using predictive models and advanced informatics (the study of information processing; computer science) to identify at-risk veterans.

One model of this type is called the medication possession ratio algorithm. It creates individualized summaries of veterans’ medication patterns, such as which medications a veteran is prescribed and how often those prescriptions are filled. The model helps clinicians pinpoint veterans with inconsistent medication usage patterns. These veterans are known to have a higher risk of attempting suicide in the next month.

In a collaborative project with the VA, a team at the U.S. Department of Energy’s Oak Ridge National Laboratory has taken the model and engineered the expanded version of it to run 300 times faster, gaining an unprecedented acceleration that might have a profound effect on the VA’s ability to reach susceptible veterans quickly.

The U.S. Department of Energy will have a scoping meeting Wednesday night for an environmental impact statement, or EIS, for a Versatile Test Reactor that could be located at Oak Ridge National Laboratory or Idaho National Laboratory.

The Versatile Test Reactor would be used to test fuels and materials for commercial nuclear power reactors.

Besides being under consideration for the Versatile Test Reactor, Idaho National Laboratory is also under consideration for the fabrication of the fuel needed to run the Versatile Test Reactor. The Savannah River Site in South Carolina is also being considered for the fuel fabrication.

The public can comment through September 4 about what should be included in a draft environmental impact statement for the reactor, according to the Tennessee Department of Environment and Conservation. DOE will publish the final EIS and make it available to the public for 30 days before issuing a record of decision, TDEC said.
