Marine construction specialist Allseas has launched an ambitious five-year plan to design, develop and deploy a small modular reactor (SMR) tailored for integration into offshore vessels and for onshore use.
The company, founded in 1985 with offices in Switzerland and the Netherlands, said it had chosen high-temperature gas-cooled reactors (HTGRs) in the 25 MW range, due to their inherently safe characteristics.
Generation IV HTGRs are powered by tri-structural isotropic (Triso) particle fuel, known for its high safety performance. Each Triso fuel particle is a small, uranium-based kernel coated with multiple layers of ceramic materials, effectively creating a tiny, self-contained “pressure vessel” that can retain fission products under all reactor conditions.
