Canada’s Terrestrial Energy has awarded KSB Pumps a supply contract to develop and manufacture primary pumps for use in the Integral Molten Salt Reactor (IMSR), a Generation IV advanced nuclear power plant.

The agreement follows a collaborative procurement process by Terrestrial Energy and KSB, and a long-term cooperation Memorandum of Understanding signed last year by the two companies.

The IMSR primary molten salt pump circulates the fuel salt from the reactor graphite core to the primary heat exchangers, and is a key component of Terrestrial Energy’s IMSR power plant.

“This contract award to KSB Pumps is an important milestone and follows an extensive procurement process led by our nuclear supply chain team,” said Simon Irish, CEO of Terrestrial Energy. “KSB is an important supplier partnership.”

“We have many years of experience in developing pumps for use in demanding operating conditions such as the high temperatures of a molten salt liquid,” said Andreas Hefter, vice president of Nuclear Energy at KSB. “We look forward to partnering with Terrestrial Energy as it leads the Generation IV sector to market with the deployment of the first IMSR power plant.”
