Rendering of the IMSR® Core-unit.
Terrestrial Energy’s IMSR® power plants are designed to deliver clean and reliable energy, support variable renewables, and drive industrial heat processes.
IMSR® power plants are virtually emission-free on a life cycle basis.
National and international efforts to develop new sources of carbon-free energy are exploring a nuclear power concept first introduced in the 1950s and 1960s: the Molten Salt Reactor. This design is vastly different from the current light water nuclear power plant and is inspiring a fresh look at the technology.
Terrestrial Energy joined forces with L3 MAPPS, the leading developer of nuclear power plant simulation technology, to support the development of the Integral Molten Salt Reactor (IMSR®), a Generation IV advanced nuclear plant design with enormous potential to transform the world’s delivery of clean, low-cost and reliable energy.
The IMSR® is being developed at Terrestrial Energy as an SMR with an output of 190  MWe of electrical production. The use of a graphite moderator and a highly thermalized neutron spectrum gives multiple advantages for standard operations. The IMSR® also offers future fuel flexibility including the ability to utilize spent LWR fuel without reprocessing but by conversion to fluoride in a dry process.
EPRI’s findings suggest that for advanced nuclear to be deployed extensively in the US, new policies, innovation in technologies that significantly lower costs, and/or innovation in business models and markets to enable supplemental revenue streams, would be needed.
The IMSR® uses a Generation IV reactor technology that leads to distinctive commercial advantages.
IMSR®-generated heat is ideal for many industrial processes, not just for electricity production.
Article in the journal Sustainability posits that timely deployment of advanced nuclear like the IMSR®—”perfectly capable of providing all the energy humanity needs for centuries”—could be the silver bullet needed for achieving aggressive Paris climate targets.
