NRC approves Terrestrial Energy IMSR principal design criteria, first for a molten salt reactor

Terrestrial Energy/IMSR

The U.S. Nuclear Regulatory Commission approved the principal design criteria for Terrestrial Energy's Integral Molten Salt Reactor, marking the first such approval for molten salt reactor technology from the NRC. This is a major gate to future construction and operating licenses.

• First NRC approval of design criteria for molten salt reactors.
• Based on Oak Ridge ORNL Denatured Molten Salt Reactor research.
• Clears major regulatory pathway to construction permit application.
