 including the power needs of data center infrastructure and industrial processes. This drives a significant market for advanced nuclear reactors. Technology Overview Nuclear reactors generate power by converting the energy released from atomic fission into electricity. Inside the reactor core, uranium fuel undergoes a controlled nuclear chain reaction that splits atomic nuclei and releases heat. This heat warms water circulating through the reactor’s primary coolant loop, which is under high pressure so it remains liquid. The hot water transfers its heat through a steam generator to a separate secondary loop, in which feedwater is converted to steam. The steam then drives a turbine connected to a generator, producing electricity. In essence, a nuclear power plant operates much like a conventional thermal power plant, but the heat source is nuclear fission rather than combustion, which means no carbon emissions are produced. The systems directly associated with the nuclear reaction and primary heat transfer are collectively called the nuclear island. This includes the reactor pressure vessel, reactor core, control rods, internal pumps, and steam generators. The systems that convert heat into electricity, such as turbines, generators, condensers, and electrical switchgear, are the balance-of-plant.Together, the nuclear island and balance-of-plantform a complete generating station. 280

| The Hadron Halo is based on LWR principles, miniaturized and optimized for modular deployment. The Hadron Halos are compact Generation III+ reactors designed for inherent safety and long-duration operation with a 10-year refueling cycle.   Hadron Energy re-envisions the well-established pressurized water reactor (“PWR”), one of the two primary types of light-water reactors used worldwide (the other being the boiling water reactor). Both use ordinary water as coolant and moderator; in a PWR the primary loop remains liquid under high pressure and transfers heat to a separate secondary loop that produces steam to drive a turbine. This configuration has become the dominant form of LWR technology worldwide due to its safety, simplicity, and extensive operating history. The majority of all reactors operating worldwide are LWRs.   Our design uses low-enriched uranium, enriched to 5-10% U-235 (“LEU+”) fuel that is a commercially available and standardized nuclear fuel supported by an existing nuclear supply chain. By leveraging this familiar reactor architecture and fuel type, Hadron Energy can benefit from decades of operating experience across the global nuclear industry, spanning plant operators, suppliers, and regulators, which reduces design risk and supports licensing and deployment.   Several key design features differentiate the Hadron Halo from other M
