Terrestrial Energy USA has secured US$3.15 million in funding from the US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) to develop a next-generation molten salt pump for use in its Integral Molten Salt Reactors (IMSR®) and other Generation IV advanced reactors.

Working with Oak Ridge National Laboratory (ORNL) and pump manufacturer Hayward Tyler Inc, Terrestrial Energy USA will use the ARPA-E funding to begin developing a more robust molten salt pump that is more efficient, requiring lower maintenance while operating at higher temperatures.

Terrestrial Energy USA received this competitive award from ARPA-E’s Modeling-Enhanced Innovations Trailblazing Nuclear Energy Reinvigoration (MEITNER) program, under which project teams develop innovative technologies for lower cost and safer advanced nuclear reactors.

“We applaud the Department of Energy’s strategic vision of supporting technologies that will expedite the deployment of Generation IV advanced nuclear power plants and improve their performance, which is the aim of the next-generation pumps we are developing for our IMSR and other Generation IV advanced reactors,” said Terrestrial Energy USA CEO Simon Irish. “Generation IV nuclear power plants, such as Terrestrial Energy’s IMSR, have the potential to play a transformative role in meeting the future energy needs of the United States and the world.”

Terrestrial Energy USA, an affiliate of Terrestrial Energy Inc, is developing the IMSR for US market deployment.
