Maritime Nuclear Energy


What is maritime nuclear?
With approximately 80% of the world’s goods transported by sea, the global shipping industry is at the heart of international commerce. Safely transporting these goods in the isolated, challenging marine environment requires reliable and durable power sources. Maritime industries support not only shipping and freight, but also offshore energy, passenger transport, desalinization, flood control and disaster mitigation. Large diesel engines, some of the most durable and reliable power sources available, have enabled maritime industries.
As the civilian power industry looks to meet growing demand with advanced nuclear energy, nuclear developers are searching for new markets for their technology. The maritime industry has now begun to explore nuclear as a powerful, cost-effective energy source.
What are we trying to accomplish?
The goal of NRIC’s involvement in the maritime sector is to support nuclear investment decisions by connecting the maritime and nuclear industries, and to encourage the demonstration and commercialization of maritime projects. To make this possible, NRIC supports advanced nuclear energy technologies through foundational studies, testing and collaboration.
History of commercial maritime nuclear
Efforts to demonstrate and develop commercial nuclear power date back to the late 1950s with the development of the NS Savannah, which entered service in 1962. There have been numerous efforts over the past 60 years to develop the technology, but notably there has been a significant push for commercial maritime nuclear since 2020.
