South Korea Plans to Build a National Collaborative Platform for Offshore Small Modular Reactors

Recently, Professor Seo Jeong of Korea Maritime and Ocean University (KMOU) proposed at the First Offshore Small Modular Reactor Network Conference held at the Busan IT Industry Promotion Agency in Busan that the commercialization of offshore Small Modular Reactors (SMRs) cannot rely solely on reactor R&D, and that a national platform linking reactor design, shipbuilding, and offshore testing must be established. The nuclear industry and the shipbuilding industry currently operate in silos, and manufacturers, research institutions, and regulatory bodies should cooperate from an early stage. Seo Jeong stated that shipborne SMRs...
