IHI to enter small nuclear reactor market

Major Japanese heavy machinery maker IHI says it is entering the market for smaller, safer nuclear reactors through a partnership with a US startup.

IHI will initially invest 20 million dollars in NuScale Power. The US firm develops so-called small modular reactors.

IHI plans to supply containment vessels for small reactors scheduled to go into service as early as 2029 in the United States.

NuScale says its reactors generate about 70,000 kilowatts of electricity, much less than conventional ones, and are easier to cool, making them safer.
Some countries have refrained from building conventional nuclear plants after the 2011 triple meltdown accident in Fukushima.

IHI says it expects demand for smaller reactors to grow as global de-carbonization efforts accelerate.
