Abundant Nuclear Energy
Made to scale
Saltfoss is developing the seaMSR-100, a molten salt power reactor designed for deployment on a shipyard produced floating platform
Key Features
We’re making nuclear energy accessible and scalable to help meet global energy needs with safe, clean and reliable power.

Long asset life
The seaMSR-100 are designed for a 24-year operational life without refueling, minimizing disruption while maintaining reliable output.

Modular and scalable
Each floating platform combines multiple 100 MWe seaMSR reactors, allowing configurations from 100 to 600 MWe to match different grid and industrial demands.

Low cost energy
Inherent safety and low‑pressure molten‑salt design reduce system complexity, enabling efficient centralized shipyard manufacturing resulting in significantly lower cost of energy than traditional nuclear and even fossil plants.

Near-zero emissions
Our floating nuclear power plants provide firm, low-carbon baseload power that can replace coal and gas plants and avoid tens of millions of tonnes of CO₂ over their lifetime.

Small footprint
Inherently safe compact reactors on floating platforms deliver large amounts of dispatchable power from a small footprint, siting dense energy production close to coastal cities and industrial hubs.

Factory produced and scalable
Through the integration of SMR and micro reactor construction philosophies, each floating platform is fabricated at the shipyard as a fully standardized, turn-key, and genuinely scalable energy solution.

The European-Korean partnership
Saltfoss’ Korean collaboration is central to turning floating nuclear power plants into an industrial reality. Samsung Heavy Industries brings world-class shipbuilding and platform manufacturing capability, KHNP adds nearly 50 years of nuclear operating experience, and KEPCO NF and GS E&C strengthen the path toward fuel licensing and production.
Together, these partners combine shipyard execution, nuclear operations and fuel expertise in one industrial ecosystem, giving Saltfoss a stronger foundation for building floating nuclear power plants at scale.
Saltfoss's Gen-IV seaMSR Power Platform represents a solution that will help decarbonize the most energy intense industries at the massive scales needed.
