The Nuclear Energy Maritime Organization (NEMO) has welcomed a new Memorandum of Understanding between the United States and the United Kingdom under the Technology Prosperity Deal. The agreement aims to speed up work on regulatory, safety, and operational frameworks for maritime nuclear technologies, including floating nuclear plants and nuclear-powered merchant ships.
NEMO called the deal a major step toward decarbonizing shipping and coastal industries, strengthening logistics resilience, and enabling safe and sustainable nuclear deployment at sea.
“By combining U.S. and U.K. expertise, regulation, and research capacity, this partnership will help align global frameworks and ensure maritime nuclear projects are built on safety, security, and environmental protection,” NEMO said.
The insurance sector also voiced strong support. Mark Popplewell, Managing Director at Nuclear Risk Insurers and Vice-Chair of NEMO’s Annorax Working Group, said the collaboration will reduce uncertainty for insurers and could pave the way for early nuclear prototypes:
“Unified regulatory clarity enables insurers to underwrite with confidence,” he said. “A bilateral liability convention would further support risk management and help create a dedicated nuclear corridor.”
Next Steps
NEMO plans to work closely with U.S. and U.K. regulators, provide technical input on draft standards, and engage its members, classification societies, and insurers in harmonizing safety and insurance requirements. It will also support joint research, pilot projects, and workforce training to prepare for future deployment.
