The American Bureau of Shipping has granted approval in principle to KRISO's design for a 15,000 TEU container ship powered by a molten salt small modular reactor (SMR), confirming technical feasibility and safety. KRISO will now proceed to basic and detailed design phases ahead of demonstration and commercialisation of SMR-powered vessels.

This Wire brief sits within Fusion42's coverage of Maritime Tech and Clean Energy. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

The Wire takeaway

You're building molten salt reactor components, maritime cooling systems, or nuclear fuel handling equipment—there's now a concrete 15,000 TEU ship design moving into detailed engineering with a major classification society's sign-off. KRISO's shift from concept to build phase means suppliers have 24-36 months to qualify systems before the first prototype docks.
