Korean researchers working with Samsung Heavy Industries have cleared a key hurdle in their efforts to develop designs for a containership powered by molten salt nuclear reactors. The American Bureau of Shipping (ABS) granted basic design approval, an AiP, for the project, reports the Korea Atomic Energy Research Institute.

The Korea Atomic Energy Research Institute is working jointly with the Korea Research Institute of Ships & Ocean Engineering and Samsung Heavy Industries on the design of a 15,000 TEU vessel with nuclear power.

The companies point to the safety and efficiency achieved through the use of molten salt. It combines nuclear fuel with the molten salt, which is a safety feature as it would harden if the reaction failed, encasing the nuclear material. //

The key feature of their concept is two Small Modular Reactors (SMRs) employing the molten salt technology. They point to a redundancy with the two reactors as well as a power system design to efficiently manage the reactors’ output against the ship’s power demands. They also incorporated a surplus power storage capability that could provide power when needed. //

ABS reviewed and verified the technical feasibility and safety of the technology and design. The receipt of the Approval in Principle (AiP), the group said, is a “confirmation of the potential of marine nuclear technology.”
