The US Nuclear Regulatory Commission (NRC) has issued its final safety evaluation approving the fuel qualification methodology topical report* for the advanced fuel design to be used in Nano Nuclear’s Kronos micro modular reactor (MMR) energy system.

US-based Nano Nuclear said this important regulatory milestone marks the culmination of a rigorous review process and represents a major step toward deployment of the its Kronos reactor prototype at the University of Illinois Urbana-Champaign.

The approved fuel qualification methodology defines the regulatory framework and testing approach for the qualification of fully ceramic microencapsulated (FCM) fuel, which incorporates tri-structural isotropic (Triso) fuel particles embedded in a silicon carbide matrix.
