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 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.
