ARC Clean Technology entered a Strategic Partnership Project agreement with Idaho National Laboratory to support the design, demonstration, and deployment of the ARC-100 sodium-cooled fast reactor. The collaboration provides the company access to laboratory facilities and technical expertise for the full lifecycle of the 100-MWe unit. This project will proceed through the standard Nuclear Regulatory Commission licensing process rather than expedited federal authorization pathways.

Earlier this week, ARC Clean Technology announced that it has entered into a Strategic Partnership Project agreement with Battelle Energy Alliance—the management and operating contractor of Idaho National Laboratory.

That agreement establishes a multiyear framework for ARC and INL to collaborate on the design, demonstration, and first deployment of the company's ARC-100, a 100-MWe sodium-cooled fast reactor.

The background: ARC stands out in a sea of reactor start-ups as perhaps the oldest in the group. The Washington, D.C.–based company was founded in 2006, before other long-standing industry names like TerraPower (founded in 2008), X-energy (founded in 2009), and Oklo (founded in 2013).
