Small Modular Reactor for Marine Propulsion
25 MWe-class high-temperature gas-cooled reactor with TRISO fuel under development for marine propulsion, auxiliary power and onshore industrial clusters.
Description
Allseas is designing a Small Modular Reactor based on High-temperature Gas-cooled Reactor (HTGR) technology for energy-intensive offshore vessels and onshore industrial clusters, intended for marine propulsion and auxiliary power.
Key features
- Compact 25 MWe-class reactors
- TRISO fuel particles
- Passive safety: the reactor self-regulates, needs no external cooling or operator intervention, and shuts down and cools automatically on malfunction
Applications
- Marine propulsion and auxiliary power for offshore vessels
- Onshore industrial clusters
Roadmap: design studies and pre-licensing with ANVS (2025–2026), basic and detailed design and testing (2027–2028), start of production at a dedicated facility (2029–2030), and initial deployment on land from 2030 followed by offshore roll-out. Partners include Lloyd's Register, TNO, NRG PALLAS, TU Delft, C-Job Naval Architects and KVNR.
