Hadron Energy Strengthens Leadership Team with Appointments of Olivia Hand as Head of Reactor Design and Tim Bussey as Vice President of Business Development

New York, NY –November 11, 2025 — Hadron Energy, Inc. (“Hadron”), announces the appointment of Olivia Hand, P.E. as Head of Reactor Design and Tim Bussey as Vice President of Business Development.

Olivia Hand brings 18 years of experience in nuclear system and component design, thermal-hydraulic analysis, and reactor component qualification across the U.S. advanced reactor industry. Before joining Hadron, Olivia held roles at TerraPower as the Lead Principal Engineer for the Natrium intermediate heat exchanger component design and prior to that was the system-level thermal hydraulics lead, where she was responsible for development of the event design basis and thermal hydraulic analysis input for the ASME thermal loading specification. She previously spent more than a decade at NuScale Power, as a key engineer advancing the NPM-160 and NPM-20 small modular reactor designs from the conceptual design stage through successful licensing. Olivia’s contributions at NuScale include component sizing, design and analysis of safety systems, performing and directing thermal-hydraulic and vibration analyses, definition and execution of validation testing and load characterization for ASME component design. Earlier in her career, Olivia supported the Naval Reactors Program, contributing to the design and delivery of Ford-class aircraft carrier reactor systems.

At Hadron, Olivia will lead the design and analysis of all reactor systems and components for the company’s flagship Hadron Halo Micro-Modular Reactor (MMR), a 10 MWe light-water reactor designed for factory fabrication, transportability, and a ten-year core. Her expertise in pressurized-water reactor design and analysis will guide the development of reactor cooling and safety systems as Hadron advances toward its manufacturing license submission to the U.S. Nuclear Regulatory Commission.

“Olivia’s experience with both light-water and advanced reactor systems makes her an exceptional fit for Hadron’s mission,” said Samuel Gibson, Founder and Chief Executive Officer of Hadron Energy. “She combines deep analytical skill with real-world project leadership, and her work will be instrumental in ensuring the Halo’s performance, safety, and manufacturability as we move from design to deployment.”

Olivia holds bachelor’s degrees in Chemical and Nuclear Engineering from the University of California, Berkeley, and a master’s degree in Nuclear Engineering from Pennsylvania State University. She is a licensed Professional Engineer in Mechanical-Thermal Fluids (Oregon) and an active member of ASME and the American Nuclear Society.

Tim Bussey brings over twenty years of experience in nuclear operations, engineering management, and large-scale energy infrastructure to Hadron’s executive leadership team.

Before Hadron, Tim was a Data Center Campus Facility Manager at Meta in Papillion, Nebraska, leading operations and maintenance for a major hyperscale data center campus. He managed teams for critical power, cooling, and operational readiness across Meta’s global infrastructure, ensuring 24/7 reliability, safety, and efficiency.

Tim began his career in the U.S. Navy’s Nuclear Propulsion Program, serving aboard the USS Enterprise (CVN-65) as an Engineering Laboratory Technician, where he supported the operation and chemistry control of eight reactor plants. Following his naval service, Tim transitioned to the commercial nuclear industry, spending more than fifteen years at Omaha Public Power District’s Fort Calhoun Nuclear Station in senior technical and operational roles, including Principal Reactor Engineer, Reactor Engineering Manager, and Unit Supervisor. He also held a Senior Reactor Operator license from the U.S. Nuclear Regulatory Commission. Tim later served as Nuclear Fuel and Analysis Supervisor at South Carolina Electric & Gas, overseeing reactor core design, licensing, and fuel cycle management for Westinghouse units.

As Vice President of Business Development, Tim will lead Hadron’s strategic partnerships, customer engagement, and market expansion initiatives. His background in both regulated nuclear generation and data center operations positions him to bridge the needs of industrial and digital power consumers with the capabilities of Hadron’s Hadron Halo Micro-Modular Reactor. Tim will focus on aligning Hadron’s deployment strategy with the growing demand for carbon-free, high-reliability power across datacenters, defense installations, and industrial customers.

“Tim’s leadership experience across commercial nuclear power and hyperscale data operations gives him a unique perspective on the markets our technology serves,” said Samuel Gibson, Founder and Chief Executive Officer of Hadron Energy. “He understands both the technical depth and the commercial urgency driving the next generation of clean energy deployment.

Hadron’s recruitment momentum follows its recently announced $1.2 billion definitive business combination agreement with GigCapital7 Corp. (Nasdaq: GIG), positioning Hadron to become the world’s first publicly traded light-water micro modular reactor (MMR) company. Together, these milestones reinforce Hadron’s standing at the forefront of the U.S.nuclear renaissance by advancing the delivery of secure, zero-carbon energy where it is needed most.
