| •First, our reactor core reduces the nuclear fuel required per unit of power. It does so by optimizing fuel geometry and neutron economy within the core. This allows each reactor to achieve the same energy output using less uranium, which lowers total fuel procurement costs and reduces the long-term volume of used fuel that must be stored and managed. The resulting decrease in spent fuel volume can reduce both interim fuel storage and eventual fuel reprocessing or disposal costs over the reactor’s lifetime.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 |     |                              |

| • |     | Second, the reactor core is engineered to operate at a lower power density than conventional large reactors, which reduces thermal and mechanical stresses. This “less aggressive” operating regime decreases wear on critical reactor components, including the fuel assemblies, control rod mechanisms, and coolant system equipment, thereby extending component life, improving reliability, and minimizing the likelihood of unplanned maintenance or early replacement. |

| • |     | Next, our Hadron Halo design strategically incorporates standard off-the-shelf equipment and components, eliminating the need for custom engineering. Complementing our strategy to utilize readily available LEU+ fuel, these commercially available equipment and components, including pumps, electronics, valves, and control systems, are already qualified and proven in the nuclear industry to offer superior reliability. In contrast, designing and manufacturing new or custom components requires substantial investment, extended lead times, and extensive qualification testing, which can introduce significant risks such as fabrication delays, certification setbacks, or early-stage performance failures discovered only during commissioning. Hadron Energy designs around these challenges by utilizing tried-and-true technology and well-established supply chains to source equipment and components. |

The NRC is responsible for certifying nuclear reactor designs and overseeing their operation. Because the Hadron Halo’s design is based on the same core principles as currently licensed reactors in the U.S., our path to licensing follows a well-established regulatory framework. The technology incorporated into the Hadron Halo, such as its pressurized water reactor architecture, fuel form, and coolant systems, has been proven through decades of safe commercial operation across the global LWR fleet. By building upon this established foundation rather than introducing novel or untested reactor concepts, Hadron Energy aims to reduce licensing risk and improve public confidence in the safety and reliability of its system. We believe that this use of familiar, demonstrated technology will strengthen market acceptance and reinforce our image as a provider of a safe, clean energy solution built on proven nuclear
