Pump manufacturer KSB and clean energy company Terrestrial Energy have signed a Memorandum of Understanding (MOU) to develop primary pumps for the Integral Molten Salt Reactor (IMSR), a Generation IV advanced nuclear power plant.

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

The MOU establishes a framework, timetable and the scope of collaboration, including the roles and contributions of each company, for the development of the IMSR pump.

“We have many decades of nuclear industry knowledge and experience with technically advanced nuclear-grade pumps, which we will use to develop and supply IMSR molten salt pumps,” said Andreas Hefter, vice president of nuclear energy at KSB. “Terrestrial Energy is on a clear path to market, and its IMSR Generation IV advanced nuclear technology has tremendous market potential.”

“We are pleased to be partnering with KSB’s expert team to develop and supply this important component for the IMSR power plant,” said Simon Irish, CEO of Terrestrial Energy.

Terrestrial Energy anticipates commissioning its first IMSR power plants in the late 2020s.
