Samsung Heavy and Seaborg to develop floating nuclear power plant combined with hydrogen and ammonia plants
Samsung Heavy Industries (SHI) and Seaborg signed a partnership agreement to develop floating nuclear power plants based on Seaborg’s inherently safe Compact Molten Salt Reactor (CMSR).
The floating nuclear power plant comes as a turn-key product, ready to be moored at an industrial harbor. In the harbor, a transmission cable will be connected to the electric grid onshore. An optional solution is to place a hydrogen or ammonia production plant next to the floating nuclear power plant utilizing the CO2-free fission energy to produce hydrogen and ammonia.
In the CMSR, the fuel is mixed into a molten fluoride salt which also acts as the coolant. This provides significant safety benefits. If the fuel salt should ever come into contact with the atmosphere, it will simply cool down and turn into solid rock, containing all the radioactive material within itself.
Since the fuel is chemically stable and the fission products are short-lived, this waste is radiologically similar to radioactive hospital waste and can be handled using conventional methods. The remaining fuel salt will be mixed into new CMSR fuel at the fuel supplying facility. In this way the challenges of long-term storage will be avoided in the future.
The agreement includes development of hydrogen production plants and ammonia plants, as the CMSR is an ideal power source for supply of stable, clean, and safe electricity, Seaborg said. The aim of the strategic partnership is to manufacture and sell turn-key power plants, ready to be moored at industrial harbors and connected to the electric grid onshore.
The stable production of energy also offers a fundamental basis for production of all Power-2-X fuels, where especially hydrogen and ammonia are considered a future energy source to replace traditional fossil fuels. The design of the hydrogen, ammonia and power units will be optimized for efficient serial construction at SHI’s shipyards.
The floating nuclear power plant design is modular, delivering up to 800 MW-electric for the 24-year lifetime and cost-competitive whether it plugs into the grid in an existing coal port or power production of hydrogen and ammonia.
