Expert Statements
Simon Irish, CEO of Terrestrial Energy
“This submission can change how an IMSR Plant is regulated, built and financed.”

“With its NRC approval, only the nuclear portion of the plant would follow the nuclear licensing timeline.”

“The rest of the plant would become a conventional industrial project, giving customers earlier power and heat and giving financing partners a bankable construction phase.”
Simon Irish, CEO of Terrestrial Energy
“As this pathway applies to every IMSR Plant, it is a fleet-wide advantage, not a one-off exemption.”
