Hadron Energy (Nasdaq: GIG) announced on December 3, 2025 that the U.S. Nuclear Regulatory Commission has formally accepted for review Hadron's Quality Assurance Program Description (QAPD) Topical Report for the Halo Micro-Modular Reactor (MMR).

The NRC's completeness determination allows formal docketing and sets an initial review schedule, expected Requests for Additional Information (RAIs) and Regulatory Confirmatory Items (RCIs) timing based on an assumed 30-day response window, and estimated staff-hour allocations; the agency noted the schedule may change if technical issues arise.

Hadron Energy and GigCapital7 (Nasdaq: GIG) filed a joint Form S-4 with the SEC on November 13, 2025 in connection with their previously announced $1.2 billion definitive business combination signed September 29, 2025.

The filing contains transaction terms, corporate governance, financial statements, and details on Hadron’s Halo™ 10 MWe light‑water micro‑modular reactor (MMR), designed for transportability, manufacturability, and long‑duration operation. The parties are targeting to close the merger during the first half of Q1 2026, positioning Hadron to become the world’s first publicly traded light‑water MMR company.

Hadron Energy (GIG) appointed Olivia Hand as Head of Reactor Design and Tim Bussey as VP of Business Development on November 11, 2025. Olivia brings 18 years in reactor system and thermal-hydraulic design, with prior roles at TerraPower, NuScale Power, and Naval Reactors; she will lead engineering for the Hadron Halo Micro-Modular Reactor (10 MWe) and prepare for a U.S. NRC manufacturing license submission. Tim brings 20+ years in nuclear operations and data-center infrastructure, including roles at Meta, Omaha Public Power District, and South Carolina Electric & Gas; he will lead strategic partnerships and market expansion targeting data centers, defense, and industrial users. Hadron also announced a $1.2 billion definitive business combination agreement with GigCapital7 Corp to become publicly traded.

Hadron Energy (Nasdaq: GIG) is advancing regulatory readiness ahead of a $1.2Bn SPAC merger with GigCapital7. The company emphasizes its light-water micro modular reactor (Halo MMR) design and proactive engagement with the U.S. Nuclear Regulatory Commission (NRC), including attendance at Advanced Reactor Stakeholder meetings since December 2024 and a key public meeting on July 17-18, 2025.

Hadron submitted a Letter of Intent and Regulatory Engagement Plan (April 2025), filed a Quality Assurance Program Description (QAPD), and plans to file a Topical Report on Principal Design Criteria. The company says it continues NRC engagement, DOE coordination, and work on the Janus Project while remaining on track for commercialization.

Hadron Energy (Nasdaq: GIG) detailed engineering and safety features of its 10 MWe Micro-Modular Reactor, the Hadron Halo, a factory-built light-water reactor designed for continuous, carbon-free power for up to 10 years without refueling and a 50-year useful life. The design uses proven pressurized-water reactor (PWR) technology, a sealed low-power-density core in a single pressure vessel, and LEU+ fuel to enable a 10-year fuel cycle. Units are factory-assembled in under a year, transportable by truck or rail, and intended for rapid on-site installation. Hadron’s development follows a $1.2B definitive business combination agreement with GigCapital7 Corp that would make Hadron a public company.

Hadron Energy (Nasdaq: GIG) received a White House letter on October 23, 2025 recognizing its 10MW light-water micro modular reactor (MMR) program as aligned with U.S. energy resilience and national defense goals.

The letter referenced federal efforts to streamline nuclear regulatory pathways and expand resilient power for DoD sites and AI data centers. Hadron highlighted its factory-built, transportable reactors with a ten-year fueling cycle and a compact pressurized-water design intended to shorten construction timelines and reduce costs. This follows Hadron’s $1.2 billion definitive business combination agreement with GigCapital7 Corp., which will make Hadron the first publicly traded light-water microreactor company.

Hadron Energy (Nasdaq: GIG) announced that Professor Benoit Forget, Department Head of Nuclear Science and Engineering at MIT, has joined Hadron as an advisor acting independently from the university. Professor Forget founded MIT’s Computational Reactor Physics Group and led development of OpenMC and OpenMOC, tools for high-fidelity neutron transport and multiphysics analysis.

The release cites his expertise in Monte Carlo/deterministic transport, multiphysics coupling, and uncertainty quantification. Hadron recently signed a $1.2 billion definitive business combination with GigCapital7 to accelerate microreactor development and become the first publicly traded lightwater microreactor company.

Hadron Energy, a pioneer in Micro Modular Reactor (MMR) technology, announced a $1.2 billion business combination with GigCapital7 Corp. (NASDAQ: GIG). The merged entity will become the first publicly listed light water micro modular reactor company, trading under the symbol "HDRN".

Hadron's innovative MMR technology delivers 10 megawatts of electricity (MWe) and 35 megawatts of thermal heat (MWth) on a 10-year fueling cycle. The reactor is designed for efficient transportation in standard shipping containers and requires minimal land compared to wind and solar alternatives. The company has already secured interest from 6+ potential customers across data centers, industrials, and government sectors.

The transaction includes $200 million in net proceeds from GIG's trust account (assuming no redemptions) and is expected to close in Q1 2026. Existing Hadron security holders will receive 100 million shares of GIG stock.
