Atomic Show #288 - Per Peterson, CNO, Kairos Power Rod Adams 25 January 2021 Atomic Insights atomicinsights.com/atomic-show-288-per-peterson-cno-kairos-power/Kairos Power is developing an innovative reactor fueled with TRISO pebbles and cooled with molten fluoride salt. The podcast is excellent. (Comment revised after 23 hours.) |

TVA, Kairos Partner to Deploy Molten Salt Nuclear Reactor Demonstration Sonal Patel 08 May 2021 POWER Magazine www.powermag.com/tva-kairos-partner-to-deploy-molten-salt-nuclear-reactor-demonstration/This innovative reactor uses TRISO pebbles for fuel and molten fluoride salt for coolant. "'Kairos Power's singular objective for deploying the Hermes Reactor is to demonstrate the capability to deliver an advanced reactor at the costs necessary to make nuclear power the most affordable source of dispatchable electricity in the United States,' [the company] said on Thursday." (For more on the Hermes Reactor, please see David B. Benson's comment on March 6, above.) |

Why 'nuclear batteries' offer a new approach to carbon-free energy David L. Chandler, Massachusetts Institute of Technology 25 Jun 2021 Tech Xplore techxplore.com/news/2021-06-nuclear-batteries-approach-carbon-free-energy.html According to the journal article on which this story is based, the cost of electricity would be about 70 $/MWh. But for many applications there would be no delivery charge for the electricity, so the cost would be competitive. The reactor could also supply heat. |

' nuclear batteries' [from] Massachusetts Institute of Technology... for many applications there would be no delivery charge for the electricity As a recent design for a nuclear battery it takes advantage of the recent perception that uranium fuel is cheap, so focuses on being dollar-efficient, rather than fuel-efficient. The long history of nuclear reactor design has been burdened by the perception that uranium is rare and expensive, or that enrichment is expensive. Neither is still true, as uranium has been found all over the world, including as byproduct in copper and phosphate ores. Enrichment is now done with centrifuges, and imminently by laser excitation. So fuel efficiency is no longer necessary in power plant designs. The generator is a once-through, hot-air turbine. In common with the gas turbine, it has low thermal efficiency, but is responsive to sudden shifts in the load or renewables injection. In acknowledging the latter, the design has adapted to the current ideological environment where wind or solar provides virtue to its believers, and the grid is required to accept and level out the intermittent contribution. When the power plant is placed alongside a wind farm, their combined output can supply the neighborhood with levelled, on-demand power up to 10 MW. As a container-sized nuclear power plant, the plant is easily and rapidly installed on location at a factory or minesite. The article makes the point that the plant can provide 10 MW to its adjacent consumer without needing a long 10 MVA connection ("delivery cost") to the trunk of the grid. After an early closure of its host consumer, the plant is easily transported to a new location and consumer. It would be good to see a more complete diagram than the "artist's impression" supplied in Huon's link. In particular, responsiveness requires a heat store to store during favorable wind for later delivery, and also provide fast heat whenever the reactor is more slowly creating or burning off excess xenon. Emergency cooling for scrams is not visible either. More details (scroll down), but no diagram |
