 industrial base investments reduce risk for components, and infrastructure. Signiﬁcantly lower regulatory burden on Hadron’s application May potentially avoid lengthy environmental impact reviews and other regulatory hurdles Hadron qualiﬁes under MMR guidance, accelerating the review process Lowers licensing uncertainty and reduces technical and ﬁnancial risk Even though Hadron uses LEU+ (not HALEU), a faster NRC is equally beneﬁcial for LEU+ designs Ability to negotiate pilot sitings on federal sites earlier for demonstration and validation IMPACT TO HADRON P. 14/22 MIRCOREACTOR POLICY TAILWINDS

Better ﬂux control means reduced localized burnup, enabling longer fuel cycles and fewer outages for refueling. Our 10MW requires a fraction of the land compared to wind and solar, making it a space-efficient path to reliable decarbonization. Strategic placement of burnable poison in the 10×10 array smooths out excess reactivity, keeping power distribution even across the core. Less aggressive reactor
