NASHVILLE, Tenn. – July 16, 2021 – Tennessee Gov. Bill Lee, Department of Economic and Community Development Commissioner Bob Rolfe and Kairos Power officials announced today that the privately funded, advanced nuclear engineering company will establish a low-power demonstration reactor in Oak Ridge.
- Tennessee's Department of Economic & Community Development Newspiece

This completes the acquisition of the East Tennessee Technology Park (ETTP) site, initially selected for the project back in December 2020. At the same time, Kairos also received $303 million in funding from the U.S. Department of Energy and Office of Nuclear Energy’s program for Risk Reduction projects to support the design, licensing, and construction of the reactor.

Kairos Power will invest $100 million and create 55 jobs to deploy a low-power demonstration reactor, called HERMES, at the site in Tennessee.

“Oak Ridge continues to lead the nation in groundbreaking technology, and we recognize Kairos Power for joining this effort. I’m proud of the energy development happening in Tennessee that will positively impact the U.S. and the world. We thank Kairos Power for choosing to develop their test reactor here in Tennessee to support their mission of developing innovative nuclear technology that will move the U.S. forward.” – Gov. Bill Lee

HERMES, expected to be operational in 2026, will demonstrate the company’s capability to deliver low-cost nuclear heat. It is a scaled version of Kairos Power’s Fluoride Salt-Cooled High-Temperature Reactor (KP-FHR), an advanced reactor technology that aims to be cost-competitive with natural gas in the U.S. electricity market in order to provide carbon-free, affordable, and safe energy. The project will be a redevelopment of a site at the Heritage Center, a former U.S. Department of Energy site complex.

“The Oak Ridge Corridor is at the forefront of science and technology in the U.S. and this partnership with Kairos Power is a huge accomplishment for Tennessee and the nuclear energy world. The combination of resources working to deliver innovative nuclear energy is fueled by our strong science and energy sector and the excellent work being done daily at Oak Ridge National Laboratory, led by Dr. Zacharia. I congratulate Kairos Power on this groundbreaking project.” – TNECD Commissioner Bob Rolfe

"The City of Oak Ridge has a long and distinguished history of nuclear innovation. The citizens of Oak Ridge look forward to welcoming Kairos Power into to our community and working with this exciting innovative project to ensure their long-term success."  Oak Ridge City Manager Mark Watson

First-year graduate student Christopher Reis has won second place for his poster entitled Investigating the limits of high-temperature superconductors for high radiation environments with the US-Japan HEP collaboration, at the US-Japan Hawaii Symposium of the US-Japan Science and Technology Cooperation Program

His poster features work on radiation damage on superconductors. https://conference-indico.kek.jp/event/119/overview
Congratulations Chris!! Well done!!

The abstract for his marvelous paper here:
Nb-based low-temperature superconductors have underpinned the successes of particle accelerator technology over the last few decades. High-temperature superconductors (HTS) open a wider application space, enabling new capabilities for High Energy Physics, High-Field Magnetic Fusion, NMR, neutron, and X-ray scattering. With complimentary goals, expertise, and tools, our team is improving the technological readiness of these novel materials. This collaboration is centered around two main tasks: Investigating HTS technologies for high-radiation environments and measuring/modeling AC loss and field quality of HTS accelerator magnets. The insulation studies implicit to the first task have yielded a simple and scalable method to remove delamination damage of HTS REBCO tapes and seen the irradiation of new epoxies to 20 Mgy. From task one we have also shown that irradiation of these tapes above 1.80E22 n/m2 completely destroys superconductivity. For task two, the team has been employing both experimental tests and modeling to understand the practical limits of REBCO coated conductors due to a quench and methods of alleviation, and field quality of canted-cosine-theta magnets made from a round REBCO cable

UCBNE Researchers and the search for Dark Matter

UCBNE Researchers and the search for Dark Matter

UCBNE Professor Karl van Bibber and his group of researchers were featured on campus news for their recent publication in Nature introducing a new experiment to harness the "weirdness of quantum mechanics to accelerate the search for the axion, one of two leading hypothetical subatomic particles that may make up the bulk of dark matter in the universe."

This new technique, called quantum squeezing, allowed the HAYSTAC detector to search for axions at twice the speed as before. “The HAYSTAC detector was already essentially at the quantum limit, and now we’ve actually found a way of circumventing the quantum limit entirely,” said co-author Karl van Bibber, executive associate dean at Berkeley’s College of Engineering and one of the senior researchers on the HAYSTAC project. “Several theoretical works are now predicting that the axion mass is right in the frequency range where HAYSTAC is ready to go next. And we’ve got the cavities and amplifiers all lined up and ready to search.”

Researchers in Rebecca Abergel's lab obtained a small sample of einsteinium, a highly radioactive and difficult-to-obtain element, and made the first ever measurement of its bond distance. The study was published in Nature.

“Structural and Spectroscopic Characterization of an Einsteinium Complex,” has been published in Nature; A study co-led by Berkeley Lab scientist and UC Berkeley Nuclear Engineering (UCBNE) Assistant Professor Rebecca Abergel, Los Alamos National Laboratory (LLNL) scientist Stosh Kozimor, and a team of scientists: study co-authors Korey Carter, Katherine Shield (current UCBNE Grad student), Kurt Smith, Leticia Arnedo-Sanchez, Tracy Mattox, Liane Moreau, and Corwin Booth of Berkeley Lab; Zachary Jones and Stosh Kozimor of Los Alamos National Laboratory; and Jennifer Wacker and Karah Knope of Georgetown University—several of whom are graduate students and postdoctoral fellows.

The research was supported by the DOE Office of Science. Luminescence spectroscopy experiments were conducted at the Molecular Foundry at Berkeley Lab, and X-ray absorption spectroscopy at the Stanford Synchrotron Radiation Lightsource (SSRL) at SLAC National Accelerator Laboratory. With experimental facilities not available in 1952, when Einsteinium was discovered, the team measured the first-ever Einsteinium bond distance and with less than 250 nanograms of the element!

“There’s not much known about einsteinium,” said Abergel, who leads Berkeley Lab’s Heavy Element Chemistry group. “It’s a remarkable achievement that we were able to work with this small amount of material and do inorganic chemistry. It’s significant because the more we understand about its chemical behavior, the more we can apply this understanding for the development of new materials or new technologies, not necessarily just with einsteinium, but with the rest of the actinides too. And we can establish trends in the periodic table.”

The Nuclear Engineering Department is pleased to announce that Jeff Graham, a graduate student in Peter Hosemann's nuclear materials research group, took first place for his poster Cold Sprayed ODS Alloys: Mechanical Evaluation in the TMS2020 Additive Manufacturing for Energy Applications section. Cold spraying is an additive manufacturing technique based on metal-to-metal consolidation by means of high-strain-rate plastic deformation, and offers a means of creating complex parts from advanced nanostructured alloys for use in next-generation nuclear reactors. The work presented evaluated the mechanical soundness of parts made of cold-sprayed ferritic stainless steel, and has shown both where the process has promise and what challenges it confronts. His work has been critical in identifying necessary research thrusts in order to bring this technology from the laboratory to industrial application. Jeff's distinctive accomplishments reflect great credit upon himself, the Hosemann research group, and UC Berkeley Nuclear Engineering.
