GigCapital7 Corp. (GIG) filed a Rule 425 communication highlighting Hadron Energy’s regulatory progress as it approaches a $1.2Bn SPAC merger with GIG. Hadron emphasizes its light‑water design, a technology the NRC has decades of licensing experience with, currently overseeing 94 operating light‑water reactors in the U.S.
Hadron initiated early engagement with the NRC, attending an Advanced Reactor Stakeholder Meeting in December 2024 and regularly participating in public meetings to shape its regulatory strategy for the Halo MMR. On July 17–18, 2025, it publicly supported a more restrictive safety framework for microreactors. In April 2025, Hadron submitted a Letter of Intent and Regulatory Engagement Plan (REP), later aligning its updated REP with the NRC’s latest guidance. The company has filed its Quality Assurance Program Description and stated it will soon file its Topical Report on Principal Design Criteria. Hadron also engages with the DOE, including the Janus Project initiative for MMR deployment on U.S. military bases.
GigCapital7 (GIG) filed a Form 425 communication highlighting Hadron Energy’s ‘Hadron Halo’ microreactor and the parties’ proposed business combination. Hadron detailed a 10 megawatt-electric Micro‑Modular Reactor using pressurized-water reactor technology, designed for continuous, carbon‑free power for up to 10 years without refueling with a 50‑year useful life. The design places the core, pumps, and steam generator inside a single pressure vessel to minimize external piping.
Each unit targets a footprint of less than one acre and factory assembly and testing in under a year, then shipment by truck or rail for installation. The reactor is planned to use LEU+ fuel to support a 10‑year fuel cycle within established fuel supply chains. The communication references a recently announced $1.2Bn definitive business combination agreement between Hadron and GigCapital7, which, if completed, would make Hadron a publicly traded light‑water microreactor company, subject to regulatory and shareholder approvals.
