HD Hyundai is working on a cargo ship concept powered by a Small Modular Reactor (SMR) designed to carry 15,000 containers without fossil fuels. This nuclear reactor will generate electricity for the ship's electric motors, eliminating the need for large diesel engines and fuel tanks, thus increasing cargo capacity.

The planned output is about 100 megawatts. The design includes two propellers for improved maneuverability and uses heated, compressed CO₂ instead of steam to drive turbines, enhancing thermal efficiency.

The American Bureau of Shipping has approved the design's feasibility. HD Hyundai aims to establish a nuclear ship business model by 2030 and is developing a test facility in Yongin, South Korea.
