Terrestrial Energy Signs Agreement for the Supply of Steam Turbines for IMSR Nuclear Power Plant

Oakville, Ontario, Canada – November 30, 2021 – Terrestrial Energy and Siemens Energy Canada have signed a contract for the manufacturing and supply of steam turbines and other balance-of-plant equipment, such as transformers, switchgear, and motor drive systems, for the Integral Molten Salt Reactor (IMSR®), a Generation IV nuclear power plant.

The IMSR® generates steam for power generation at standard utility class temperature and pressure, and from systems that are isolated from its nuclear reactor. This not only drives a transformative 50 per cent improvement in the economics of nuclear power generation, but it also simplifies engineering challenges by enabling procurement of standard utility steam turbines. In turn, this facilitates design readiness and early power plant deployment schedules. This approach eliminates the complex, costly and lengthy development schedules of highly customized turbines required by non-Generation IV reactor technologies for power generation such as BWR technology, all of which are use low temperature and non-standard industry steam supply.

Siemens Energy is a global leader in the supply of utility steam turbines to the electric power sector with a fleet of more than 60,000 steam turbines operating worldwide.

“Partnering with Siemens Energy to supply these key power plant components underscores the readiness of our Generation IV power plant design and its superior economics over SMR power plant designs that use Generation III reactor technologies,” said Simon Irish, CEO of Terrestrial Energy. “Its superior thermal efficiency and economics will be key to SMR success in a completive global market seeking a clean energy alternative to fossil fuels.”

Terrestrial Energy’s IMSR® power plant is one of three Small Modular Reactor (SMR) power plant designs under consideration for deployment at Ontario Power Generation’s Darlington Nuclear Generating Station. It is one of two Generation IV SMR technology candidates under consideration by OPG, and the IMSR® is the only Canadian SMR technology candidate.

About Terrestrial Energy

Terrestrial Energy is a developer of small and modular nuclear power plants that use its proprietary Integral Molten Salt Reactor (IMSR®) technology. The IMSR® is a non-Light Water Reactor that uses Generation IV technology to generate electricity 50 percent more efficiently than conventional nuclear reactor technology. The IMSR® represents a step-change improvement in economics, versatility and functionality of nuclear power plants that is possible only through Generation IV technology. IMSR® power plants will provide resilient, reliable, dispatchable, zero-carbon and cost-competitive electric power, as well as high-grade industrial heat for use in many industrial applications, such as chemical synthesis, hydrogen production and desalination, and in so doing extend the application of nuclear energy far beyond electric power markets. IMSR® power plants have the potential to make important contributions to industrial competitiveness, energy security, and economic growth. Their deployment will support rapid global decarbonization of the primary energy system by displacing fossil fuel combustion across a broad spectrum and can scale to meet net-zero policy goals of major industrial economies. Using an innovative design, and proven and demonstrated molten salt reactor technology, Terrestrial Energy is engaged with regulators and industrial partners to complete IMSR® engineering and to commission first IMSR® power plants in the late 2020s.
