errestrial Energy is developing revolutionary — not simply evolutionary — fission technology for electric power and hydrogen and much more. To achieve this, we use completely different nuclear technology – a molten salt as coolant and fuel in our Integral Molten Salt Reactor (IMSR®) power plant. With this technologically superior yet proven approach, IMSR® nuclear power plants are on a clear path to market and are more affordable, more cost competitive, and more versatile than conventional nuclear power plants that have been in use commercially for over 60 years.

IMSR® technology can be brought to market quickly, building them in four years to produce electricity or industrial heat at prices competitive with fossil fuels, while emitting no greenhouse gases. The first IMSR® power plants are expected to come online in the late 2020s.

IMSR® technology is today’s reliable and resilient clean energy game changer.
