Nuclear energy is not necessarily more expensive the than other forms of energy generation over the long term.

While the initial capital costs, regulatory and safety / security risks are higher than other sources of fossil fuel or renewable energy, nuclear energy’s overall cost is extremely competitive with other methods of electricity and over time can cost the consumer less in usage than other sources of energy.

Compared to other base-load electricity generation types, operating a nuclear energy plant is highly efficient and uses little fuel. Long-term savings in operations ensure that nuclear energy is economically competitive with other forms of electricity.

Kairos Power’s small modular reactor differ from conventional reactors in several ways.

Rather than water, used in conventional nuclear reactors, the Kairos Power reactor uses molten fluoride salt as a coolant. Molten fluoride salts have excellent chemical stability and tremendous capacity for transferring heat at high temperature and retaining fission products. Various U.S. reactor studies confirm the compatibility of molten fluoride salts with conventional high-temperature structural materials (e.g. stainless steel), thus enabling commercially attractive reliability and service life.
