Explore Kairos Power’s plans in a virtual open house.

By 2030, Kairos Power aims to demonstrate electricity production from a full-scale, 140-MWe fluoride salt–cooled high-temperature reactor, the KP-X. In service of that goal, Kairos plans to demonstrate Hermes, a scaled-down 35-MWth nonpower reactor, in Oak Ridge, Tenn.

Hermes is being built to “prove our ability to deliver affordable nuclear heat,” said Mike Laufer, Kairos Power chief executive officer and cofounder, as he explained Kairos’s plans to the local community during a September 28 webinar now available to view on demand. Laufer took questions, and Kairos took the opportunity to introduce a virtual open house that visitors can tour to view videos and interactive features and even submit comments.

Back in July, officials from the state of Tennessee and Kairos Power met in Nashville to celebrate Kairos’s plans to construct a low-power demonstration reactor in the East Tennessee Technology Park in Oak Ridge, Tenn. The demonstration facility is a scaled-down version of Kairos’s Fluoride Salt–Cooled High Temperature Reactor (KP-FHR), dubbed Hermes. The company first announced plans in December 2020 to redevelop the ETTP’s former K-33 gaseous diffusion plant site for construction of Hermes.

For years, pressure has been building for a commercial path to a stable supply of high-assay low-enriched uranium (HALEU)—deemed essential for the deployment of advanced power reactors—but advanced reactor developers and enrichment companies are still watching and waiting. In contrast, the uranium spot price soared after Sprott Physical Uranium Trust, a Canadian investment fund formed in July, began buying up U3O8 supplies, causing the price to increase over 60 percent, topping $50 per pound for the first time since 2012. Fueled by growing acknowledgment that nuclear power is a necessary part of a clean energy future, uranium is the focus of attention from Wall Street to Capitol Hill.

In an op-ed published online yesterday in The Hill, Ted Nordhaus and Adam Stein of the Breakthrough Institute pick apart arguments made against funding for the construction of the Versatile Test Reactor at Idaho National Laboratory. Nordhaus and Stein contend that opposition to the VTR has been led by “entrenched opponents of nuclear energy” who “fear that innovation of the sort that many U.S. nuclear startups are presently betting on might give the technology a second life.”

U.S. Nuclear Nexus created to guide exporters of advanced nuclear technology

August 23, 2021, 12:00PMNuclear News

Companies, universities, and national laboratories across the United States are working together to develop and demonstrate advanced nuclear technologies. To deploy those technologies on a global scale and maximize U.S. efforts to combat climate change, technology developers eyeing the export market must navigate rules and recommendations designed to ensure that international safeguards, security, and nonproliferation standards are met. Understanding and, where appropriate, integrating these standards early in the development process is crucial for streamlining export and technology deployment.

At the box office or streaming at home, it’s fear, not truth, that sells. The laws of physics are swept aside, apocalypse is inevitable, and superpowered heroes wait until the last possible second to save the universe. It can make for great entertainment, but in the real world we need to stick with science over science fiction and be wowed by engineering, not special effects.

The truth is, science and innovation are incredible in their own right. From communications and machine learning to space travel and medical advances, technology is evolving in hyperdrive to solve real problems. With climate change and global warming here on earth, we don’t have to go looking for trouble in a galaxy far, far away.

The Nuclear Waste Technical Review Board (NWTRB) has released a comprehensive and highly technical report on the Department of Energy's research efforts into high-burnup spent nuclear fuel. The NWTRB is an independent federal agency tasked with evaluating the technical and scientific validity of DOE activities related to managing and disposing of high-level radioactive waste and spent nuclear fuel.

The NWTRB report to the U.S. Congress and the secretary of energy, Evaluation of the Department of Energy’s Research Program to Examine the Performance of Commercial High Burnup Spent Nuclear Fuel During Extended Storage and Transportation, was posted to the board’s website on August 2. It is a product of a multi-year effort during which the NWTRB reviewed the DOE’s research activities into the performance of high-burnup spent nuclear fuel (SNF) in extended storage and transportation conditions.
