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.

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.

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 VTR is “crucial” for U.S. national security, Atlantic Council leaders contend

August 4, 2021, 9:30AMANS Nuclear Cafe



An article written by national security experts Thomas Graham Jr. and Richard W. Mies, published online in The National Interest on August 3, argues that a recent move by the House Appropriations Committee to zero out the budget for the Versatile Test Reactor “has grave ramifications for U.S. national security and the fight against climate change.” Funding and building the VTR would present an opportunity for the United States to regain its leadership role in nuclear reactor designs and fuel, Graham and Mies assert.

Former ambassador Graham is chairman of the board of Lightbridge Corporation and former general counsel and acting director of the U.S. Arms Control and Disarmament Agency. Retired admiral Mies served as the fourth commander in chief of U.S. Strategic Command. Graham and Mies serve as cochairs of the Atlantic Council’s Nuclear Energy and National Security Coalition.

Kathryn Huff, the Department of Energy’s acting assistant secretary for nuclear energy, asserted in an article published online by the Office of Nuclear Energy (DOE-NE) on July 30 that demonstration reactors, such as the Natrium and Xe-100 reactors being built as full-size power producers with cost-shared funding from the DOE, and test reactors, such as the Versatile Test Reactor, are both necessary for nuclear innovation. Both are also line items in the DOE budget request, and Huff’s article sends a clear message to appropriators about the need to fund both the Advanced Reactor Demonstration Program (ARDP) and the VTR.

Road to advanced nuclear: How DOE and industry collaborations are paving the way for advanced nuclear reactors

April 2, 2021, 8:58AMNuclear NewsCory Hatch

As electric utilities rush to reduce carbon emissions by investing in intermittent renewables such as wind and solar, they often rely heavily on fossil fuels to provide steady baseload power.

More than 60 percent of the nation’s electricity is still generated with fossil fuels, especially coal-fired and gas-fired power plants that have the ability to quickly ramp up or ramp down power to follow loads on the electric grid. Most experts agree that even with a radical advancement in energy storage technology, relying exclusively on wind and solar to replace fossil fuels won’t be enough to maintain a stable electric grid and avoid the major impacts of climate change.

To complete the transition to a carbon-free energy future, one key piece of the puzzle remains: nuclear power.

Axios reviews “green” fuel options for commercial shipping

March 10, 2021, 12:01PMANS Nuclear Cafe

In an article published on March 5, Axios reviews the ways the world’s maritime companies are trying to decarbonize. The maritime industry, “from ferries to freighters—is trying to navigate a once-in-a-century transition away from fossil fuels to new, cleaner means of propulsion,” the article explains.

Emissions from shipping: The article notes that the world’s economy relies on international shipping, with more than 90 percent of global trade traveling via maritime vessels. The issue, though, is that “the vessels burn about 4 million barrels of oil a day, accounting for almost 3 percent of the world’s carbon emissions.” The article then cites a United Nations report from 2018 that sets greenhouse gas reduction targets of 50 percent by 2050 compared to 2008 levels.

Fuel innovation: Powering nuclear modernization
