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 power lines proposed at Horizon Center will be discussed during a Tuesday lunch in Oak Ridge.

The project, advocated by Oak Ridge officials for industrial development, has raised concerns among environmentalists and people who use the city’s greenways.

The guest speaker at Lunch with the League on Tuesday, January 7, will be Virginia Dale. Dale is a corporate fellow emeritus with Oak Ridge National Laboratory, where she worked in the Environmental Sciences Division. She is currently a researcher in the Ecology and Evolutionary Biology Department at the University of Tennessee, a press release said. Dale has been the author of 11 books and more than 250 published articles.

Her presentation on Tuesday will focus on the city’s recent action to seek authorization from the U.S. Department of Energy to build an electric transmission line along the DOE patrol road on the boundary between the Black Oak Ridge Conservation Easement and the Horizon Center industrial park, or by cutting through other “natural areas,” the press release said. These “natural areas” are identified in mitigation conditions required for a federal finding of no significant impact, which allowed the subsequent development of the Horizon Center, the press release 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.

President Donald J. Trump formally nominated Dan Brouillette to serve as the next energy secretary on Thursday.

Brouillette, a former Ford executive, is currently deputy secretary in the U.S. Department of Energy. If confirmed by the U.S. Senate, he would replace Rick Perry, who is resigning as energy secretary.

“I am honored to be nominated by President Trump to serve as the U.S. secretary of energy, and grateful to Secretary Perry for asking me to join him at the Department of Energy over two years ago,” Brouillette said in a DOE press release on Thursday. “If confirmed, I will further Secretary Perry’s legacy of promoting energy independence, innovation, and security for the American people.”

Brouillette has visited DOE sites in Oak Ridge as deputy secretary, while Perry has visited as energy secretary, including to announce Frontier, a new supercomputer at Oak Ridge National Laboratory, in May.

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.

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.

Rick Perry

U.S. Energy Secretary Rick Perry will resign sometime later this year.

The resignation was announced in a letter from Perry to President Donald Trump on Thursday. The U.S. Department of Energy provided a brief statement about Perry’s resignation in a press release on Thursday and included a copy of his resignation letter.

The Thursday letter didn’t give a specific date for Perry’s resignation, except to say that he plans to “resign at a date later this year.”

“The secretary is immensely grateful to President Trump and the American people for this opportunity to serve and looks forward to continuing to support the president’s agenda after he returns home to Texas later this year,” the DOE statement said.

During a visit to Oak Ridge National Laboratory in May, Perry dismissed a news story that he planned to leave DOE, and he suggested the story was the product of a “rumor factory.”

Centrus Energy Corporation on Wednesday said it has successfully completed a $15 million project to decontaminate and decommission a building at the East Tennessee Technology Park that has been used to test and demonstrate centrifuges that could be used to enrich uranium.

The building is K-1600, which is in the middle of the former mile-long, U-shaped K-25 Building at East Tennessee Technology Park in west Oak Ridge.

Centrus said it finished the work budget and on time, within a year. The work was to occur between October 1, 2018, and September 30, 2019.

“I’m pleased our team was able to deliver the results the department expected on a very short timetable,” said Centrus President and Chief Executive Officer Daniel B. Poneman.

The U.S. Department of Energy awarded Centrus a $15 million work authorization on September 27, 2018, to prepare K-1600 for demolition.
