With Washington State DOH licenses in place, Helion moves closer to delivering commercial fusion power

EVERETT, Wash. – June 16, 2026 – Helion, a Washington-based fusion energy company, today became the first company in the world to secure the regulatory licenses needed for a fusion power plant, following receipt of two licenses from the Washington Department of Health (DOH). The licenses – Radioactive Materials License (RML) and Radioactive Air Emissions License (RAEL) – mark a major milestone for the company, confirming Helion has the facilities, trained personnel, and safety programs in place at its Orion facility in Malaga, WA, to meet the rigorous safety standards required for fusion operations.

These licenses demonstrate Helion’s commitment to engaging early and often with state regulators to ensure compliance with system requirements. They enable Helion to continue building on the site of Orion, the world’s first fusion power plant.

“We are extremely proud to be granted these licenses from the Washington DOH, making us the first company in the world with the regulatory approvals in place for fusion power plant operations,” said David Kirtley, CEO of Helion Energy. “We have a long history of working with the DOH to license our previous fusion activities. Today’s announcement represents the rigor of that work and opens the door for practical, commercial, safe fusion power.”

The Washington DOH is the licensing body for fusion power in the state, following the U.S. Nuclear Regulatory Commission’s decision to regulate fusion under the byproduct material framework, alongside particle accelerators and hospitals, rather than like nuclear fission reactors. This distinction, codified by Congress in the bipartisan ADVANCE Act of 2024, reflects fusion’s fundamentally different safety profile and enables a right-sized path to deployment. Washington’s pathway was strengthened by bipartisan state legislation in 2024 and 2025 – HB 1924 and HB 1018 – that clarified fusion’s role in clean energy policy and provided permitting certainty for fusion power plants.

1. Fusion fuel: where does it go after fusion occurs?

A look into Helion’s closed-loop fuel system

The journey of fusion fuel in Helion’s system doesn’t end when fusion stops; it’s just getting started. In a closed-loop system, it follows a carefully managed path: fuel enters the machine, part of it fuses, the exhaust is captured, the valuable components are analyzed and separated, and the usable fuel is prepared to go back in again. For Helion’s approach, that path begins with a subset of three key fuels—deuterium, helium-3, and tritium—and each one takes a different path following a fusion pulse.

In this article, we explore the path of fuel particles through our pulsed power system and show how they’re recovered and recycled in the fuel cycle for the next round of fusion.

Fuel enters the machine

Helion’s machines operate with several fuel mixtures, including deuterium-deuterium (D-D), deuterium-tritium (D-T), and, deuterium-helium-3 (D-He-3). Gas is injected into the machine, where it is ionized into a plasma, and is accelerated, merged, and compressed to fusion conditions. At that point, one of two things happens: a particle either participates in fusion or it doesn’t.

If it fuses, it becomes a new particle: a helium isotope, proton, neutron, or tritium. If it doesn’t, it remains as unburned fuel.
