 burden on Hadron’s Nuclear Regulator reactors like Hadron’s application Commission • May potentially avoid lengthy environmental impact • Use of LEU+ fuel aligns safety and materials evaluations (NRC) with precedents reviews and other regulatory hurdles • Allocates HALEU, planning fuel supply base, backing • Eﬀorts signal a favorable policy orientation toward Department of pilot deployments reactor projects Energy (DOE) • DOE supply-chain and industrial base investments • Building out the fuel ecosystem, so reactor projects reduce risk for components, and infrastructure aren’t starved for fuel P. 9/22 FEDERAL SUPPORT FOR NUCLEAR

CONFIDENTIAL One Platform. Endless Energy Applications. Hadron’s micro modular reactors redeﬁne versatility—serving as both power plants and heat sources for a variety of sectors. By integrating electricity and process heat in one deployable system, Hadron will unlock new economic value, shorten project timelines, and accelerate the transition to sustainable energy infrastructure worldwide.

CONFIDENTIAL HADRON’S UNIQUE CORE DESIGN Hadron’s core uses a modular 5×5 lattice of 10×10 rod assemblies. Each assembly blends fuel rods with strategically placed burnable poison for lifecycle reactivity shaping, plus integrated control rods for maneuverability and shutdown. The result is balanced power distribution, effi- cient fuel use, and ﬂexible operation from startup to end-of-life. BENEFITS: Modular Scalability Improved Power Flattening Our 10MW requires a fraction of the Strategic placement of burnable land compared to wind and solar, poison in the 10×10 array smooths making it the most space-efficient out excess reactivity, keeping
