The staff will hold a meeting on March 23, to discuss the safety and environmental review processes and take comments. Meeting details will be available by March 11 on the NRC’s public meeting calendar or the agency webpage on the Kairos application.
The KP-FHR is said to be “a novel advanced reactor technology that leverages TRISO (TRi-structural ISOtropic particle) fuel in pebble form combined with a low-pressure fluoride salt coolant.” The technology uses an efficient and flexible steam cycle to convert heat from fission into electricity, the company said.
Rather than water, as used in conventional nuclear reactors, the Kairos Power reactor uses molten fluoride salt as a coolant. Molten fluoride salts are said to have excellent chemical stability, and great capacity for transferring heat at high temperature and retaining fission products. Various U.S. reactor studies have confirmed the compatibility of molten fluoride salts with conventional high-temperature structural materials (such as stainless steel), thus enabling commercially attractive reliability and service life, according to Kairos Power.
