 Halo unit, including the reactor module and its accompanying balance-of-plant, are sized for transport by standard heavy-haul tractor-trailers, railcars, or barges. The primary components of each Hadron Halo are transported on skids or in standard shipping containers for quick installation. Transportable, modular units enable us to serve locations that large plants or long transmission lines cannot easily reach. |

Hadron Halo Transportability Illustration

| • |     | Compact Footprint: Each Hadron Halo is expected to have a footprint of less than one acre of land. This significantly reduces land requirements compared to renewable energy generation; for example, achieving an equivalent 10 MWe of electrical output from wind or solar would potentially require hundreds of acres, in addition to space for battery storage systems. The compact footprint allows for placement at existing industrial sites or data center campuses. |

| • |     | Scalable Capacity: Because of the Hadron Halo’s modular design, capacity can be scaled by adding multiple units, for instance 10 units for 100 MWe, to meet larger power requirements with a phased, incremental approach. |

| • |     | Power Output and Use Cases: The Hadron Halo produces approximately 35 MWth, converted to 10 MWe of electricity. These estimates reflect continuous 24/7 output at a 93% capacity factor. Unlike renewables requiring 50–500 acres for equivalent capacity, the Hadron Halo and its balance-of-plant occupy under one acre, enabling compact deployment at industrial sites or data campuses. |

| • |     | Safety: Safety is central to our technology. Our reactor core is self-regulating and passively cooled in emergency situations, leveraging highly reliable fuel and modern control systems to ensure safe shut-down without external intervention. We intend for the design of the Hadron Halo to meet or exceed NRC safety requirements for advanced reactors, including recent MMR guidance. |

| • |     | Shielding: To ensure public and personnel safety, the Hadron Halo includes robust, multi-layer shielding engineered to contain gamma and neutron radiation within the reactor module. |

In summary, by combining proven LWR technology with modern engineering (advanced materials, digital controls) and a novel deployment model, we aim to reduce barriers to entry and unlock the potential of nuclear energy in markets that have never been able to deploy it before. 283
