ARC Clean Technology announced the formation of NuARC, a partnership with Calgary-based Nucleon Energy, to develop and deploy the ARC-100 sodium-cooled fast reactor starting in Alberta, Canada with potential sites under evaluation. ARC closed a Series B financing round in December 2025 with investors including Xplor Ventures, Hennessy Capital Group, Cleantech Ventures, Core Synergy, and Banpu Ventures. The ARC-100 is a Generation IV design derived from the Integral Fast Reactor with a 20-year core life without refuelling.
