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.

For the first time in 30 years, spent nuclear fuel from the High Flux Isotope Reactor at Oak Ridge National Laboratory has been dissolved at the Savannah River Site in South Carolina.

The work is important because it is expected to allow the reactor, known as HFIR, to continue its mission, according to the U.S. Department of Energy Office of Environmental Management.

HFIR, which uses highly enriched uranium, is one of the world’s most powerful nuclear research reactor facilities. It’s the highest flux reactor-based source of neutrons for research in the United States. Flux refers to the rate of flow of fluids, particles, or energy. In HFIR’s case, the flux is measured in neutrons per square centimeter per second. HFIR is used for neutron scattering and isotope production, among other missions.

ORNL will reach its maximum capacity for storing HFIR fuel in fiscal year 2020, the DOE Office of Environmental Management, or EM, said in an “EM Update” electronic newsletter on Tuesday. [Read more…]

The National Nuclear Security Administration is leading an effort to develop and qualify a new fuel that will allow high-performance research reactors in the United States that currently use highly enriched uranium to be converted to reactors that use low-enriched uranium fuel.

The research reactors that could be converted include the High Flux Isotope Reactor at Oak Ridge National Laboratory.

The goal is to develop a fuel that cannot be used in a nuclear weapon. The research reactors perform unique science and are a critical part of the U.S. nuclear complex, but all together, they use 200 kilograms of highly enriched uranium each year. That’s enough material for at least eight weapons, according to the NNSA.

On Wednesday, the NNSA said it has presented the U.S. Nuclear Regulatory Commission with a preliminary report on uranium-molybdenum (U-Mo) monolithic fuel. The report contains data about the performance of the new fuel in a reactor and how it holds up under a variety of conditions. [Read more…]

Oak Ridge National Laboratory is pursuing two major upgrades to its Spallation Neutron Source that would allow new scientific research and could cost more than $1 billion.

The two proposed upgrades are a proton power upgrade and a second target station. The two projects are in different stages of review at the U.S. Department of Energy, ORNL spokesperson Morgan McCorkle said.

The proton power upgrade, or PPU, is being pursued first, and its current cost estimate is a little more than $200 million, McCorkle said. If approved, it would double the power of SNS’s proton beam from 1.4 megawatts to 2.8 megawatts.

The upgrade would allow new types of research at SNS, and it would increase the number of scientists who can use the facility each year, McCorkle said.

“The PPU will enable experiments that are not currently feasible, such as experiments on smaller or less concentrated samples, and experiments under more extreme environmental conditions,” McCorkle said. “The new scientific capabilities will support research in areas such as soft matter, quantum materials, chemistry, functional materials, and biology. Some examples of everyday products that may be improved by these discoveries include cell phones, batteries, computers, building materials, and drugs.”

The proton power upgrade would also eventually provide the extra power necessary for the proposed second target station, or STS. The design of the second target station is less mature, but the project could cost in the range of $1 billion and include about 300,000 square feet of new buildings, McCorkle said. The second target station would be on the east end of the SNS campus on Chestnut Ridge at ORNL.

HARDIN VALLEY—He once called for eliminating the U.S. Department of Energy, but after touring federal sites in Oak Ridge and Hardin Valley on Monday, new Energy Secretary Rick Perry pledged to be an advocate for at least some programs.

Perry, a former Texas governor who was confirmed as energy secretary on March 2, was asked about his comments calling for the elimination of three federal departments, including DOE, during the 2012 presidential campaign. His call to eliminate the three departments probably received more attention than it might have otherwise because, in a moment that received a lot of attention, Perry couldn’t recall the name of the Department of Energy during a November 2011 debate. Some believe that moment helped sink his presidential campaign.

Earlier this year, Perry told U.S. senators during his confirmation hearing that he regretted his earlier call to eliminate DOE. After being briefed on many vital functions of DOE, he no longer believed that it should be eliminated, Perry told the Senate Energy and Natural Resources Committee, according to The New York Times.

During a stop in Hardin Valley on Monday afternoon, Perry acknowledged he’s learned a lot since the 2012 campaign, including in his visit to Oak Ridge and at DOE headquarters in Washington, D.C., and in trips to Idaho National Laboratory and the Waste Isolation Pilot Plant in southeast New Mexico.

He suggested he might not be the only one unaware of some of the innovations that have roots in or are developed in places like Oak Ridge, innovations like gene therapy, supercomputing, and 3D printing. The American public may also not be aware of how that “cutting-edge” technology can be used to create jobs and wealth, Perry said.

“Those are things I readily admit I didn’t know five years ago,” Perry said after operating a 3D-printed excavator and test-driving a printed utility vehicle—and learning about other innovations such as supercomputers at Oak Ridge National Laboratory and composite work at its Manufacturing Demonstration Facility in Hardin Valley on Monday afternoon. “There are a lot of things that have surprised me.” [Read more…]
