South Korea's KRISO, Samsung Heavy Industries, and KAERI received regulatory approval-in-principle from the American Bureau of Shipping for a cargo ship powered by two molten salt nuclear reactors, capable of carrying 15,000 containers at 25 knots. The design represents a shift from conventional water-cooled reactors to smaller, more efficient molten salt technology for commercial maritime propulsion.

◆ ◆ The Wire takeaway
If you build ship components, cooling systems, or radiation shielding, you now have a concrete pathway to a buyer—ABS approval means this reactor design moves from lab to build phase. The molten salt reactor on this ship needs suppliers, and the first mover captures the specification.
