…tion with the ANS Winter meeting, Ed Blandford, Chief Technical Officer of Kairos, mentioned that Kairos pebbles are smaller than the typical 6 cm pebbles chosen for most pebble-bed conceptual reactors. Smaller pebbles have the advantage of higher surface to volume ratios for enhanced heat transfer. He indicates this logical choice wouldn’t be as easy for gas cooled reactors. When I asked him why gas-cooled designs would be challenged with smaller…

Atomic Show #288 – Per Peterson, CNO, Kairos Power
…est Unit now in construction in Albuquerque Image provided by Kairos Power Kairos Power Is developing a truly new nuclear fission power technology. Their KP-FHR (Kairos Power – Fluoride Salt Cooled, High Temperature Reactor) combines the solid fuel form usually associated with gas-cooled reactors with the fluoride molten salt often associated with fluid-fuel reactors. For Atomic Show #288, my guest was Dr. Per Peterson, Kairos Power’s chief nuclea…
Kairos Power Is Hiring For Hybrid Natural Gas-Nuclear Power System
…y is seeking to fill, Dr. Peterson said that the best available summary of Kairos’s current situation is available on its LinkedIn page. Kairos deserves to have the space and patience needed to develop its technology, licensing and commercialization plans. Its current goal is to build a demonstration prototype by about 2030. Following testing and refinement, Kairos expects to be ready to enter the commercial power market in the late 2030s. Though…

China’s high temperature reactor – pebble bed modular (HTR-PM) achieves its first criticality
On the morning of September 12, 2021, reactor number 1 of the eagerly awaited HTR-PM project was taken critical for the first time. Initial criticality for any new reactor is a big deal for the people involved in the project; this one is a big deal for the future of nuclear energy. It might also become a big deal for humanity’s ability to effectively reduce CO2 emissions enough to slow climate change. HTR-PM is a demonstration reactor that uses t…
Turning nuclear into a fuel dominated business
…let temperature when they want to go To higher power operations. Actually, Kairos has decided to abandon this concept — at least for the first reactors that they intend to build. They probably will want to revisit it later, if they get the chance, but their effort to bring a reactor to market will skip this hybrid power system as too much risk and go with something more straightforward. Engineer-Poet What Kairos might want to do is come up with a…
Fission heated gas turbines address MIT Future of Nuclear challenges. Easier, straighter, less costly path
…uch as municipal utilities or manufacturing interests. scaryjello At least Kairos power wants to “co-fire” the natural gas combustion turbine with a radiator like was used for the MSRE. I love the idea of Brayton cycle using nuclear heat. Bearing lubrication is a major hurdle for “direct cycle” where reactor coolant passes through the core – the lube oil will soot-up the core and cement it together. High temperature magnetic bearings for a 10-ton…

…aturing concepts as NuScale’s natural circulation light water reactors and Kairos‘s Floride High Temperature reactors. All of them grew out of university research lab projects and all of them have been steadily led by university professors with commercial instincts. There’s still a lengthy path to commercialization, but that doesn’t invalidate the effort or the potential. PS – All reasonably well developed nuclear energy concepts have a friend at…
Catching Oklo — a rising star!
…s not behind it, it will not survive. Next to go the way of the dinosaurs: Kairos, Moltex, and half a dozen other fan favorites… Rod Adams @Michael Scarangellia I’m amused by your suggestion that people who want to see nuclear succeed – even in a place where the state is not the driving, organizing force – should go to work for Westinghouse. Isn’t Westinghouse the company that spent about 20 years designing an advanced passive reactor product (ini…
