Summary

The U.S. Nuclear Regulatory Commission (NRC) has issued the first construction permit for a commercial-scale advanced nuclear power plant to TerraPower for its Natrium reactor (Kemmerer Unit 1) in Wyoming. The 345 MW sodium-cooled fast reactor, featuring a molten salt-based energy storage system, is being developed under the DOE’s Advanced Reactor Demonstration Program. The NRC completed its review in 18 months, ahead of schedule, due to the completeness of TerraPower’s application and regulatory engagement. Construction is expected to begin soon, with project completion targeted for 2030.

Key points

The NRC approved the first construction permit for a commercial-scale advanced nuclear reactor (Natrium 1, Kemmerer Unit 1) in the U.S., TerraPower’s Natrium design is a 345 MW sodium-cooled fast reactor with a molten salt-based energy storage system, enabling flexible output up to 500 MW., The permit review was completed in 18 months, faster than the initial 27-month schedule, due to a thorough application and effective engagement., The project is part of the DOE’s Advanced Reactor Demonstration Program (ARDP), with completion targeted for 2030., This milestone follows TerraPower’s recent acceptance into the UK regulatory process, indicating growing international momentum for the Natrium technology.

Why it matters

Marks the first NRC construction permit for a commercial advanced reactor, setting a regulatory precedent for future projects., Demonstrates the viability of sodium fast reactor and integrated energy storage technologies at utility scale., Accelerated review process may inform future NRC procedures for advanced reactor licensing., Supports U.S. Department of Energy goals for advanced nuclear deployment and grid decarbonization., Follows TerraPower’s international regulatory progress, reinforcing the company’s leadership in advanced nuclear deployment.
