INHERENTLY SAFE… NO CHAIN REACTION Agile Nations Annex A: Case Study - UKAEA • Based on a D-T tokamak design fusion facility at power plant scale; however, it is expected that the findings from this analysis will be applicable to different technologies and fuel cycles • Accident Scenario (Acc 1) is a breach of primary confinement (e.g. vacuum vessel, ignoring the cryostat) but with the tokamak building containment and its filtration/detritiation (HVAC) system intact: • Potential worst-case dose (@1km) is a few micro-Sieverts = equivalent to radiation from a single transatlantic flight • Accident Scenario (Acc 2) is a breach of primary confinement with an independent malfunction such that there is leakage through the tokamak building confinement: • Potential worst-case dose (@1km) is a few milli-Sieverts = equivalent to the radiation from a CT scan of the chest INHERENTLY SAFE… NO CHAIN REACTION Regulated by the Massachusetts Radiation Control Program (MRCP) • The SPARC project is a medium-sized tokamak under construction in Devens, Massachusetts, operations to begin in 2027 with rapid ramp up to Q>2 • Two permits are required: (1) demonstrate how SPARC is managing tritium, (2) demonstrate how SPARC is managing activated materials Access Control System (ACS) – designed to industrial safety standards • The ACS is designed to prevent access to hazardous environments, other industrial safety requirements apply to high-voltage systems, cryogenics, etc.

ARC™: Putting fusion energy on the grid | Commonwealth Fusion Systems

https://cfs.energy/technology/arc/

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy, the power source of the sun and other stars, and ARC is how we’ll do it. When the first ARC plant arrives in the early 2030s, it’ll provide the electrical grid with about 400 megawatts of clean, zero-carbon, power — a firm source customers can count on having when they need it. **ARC is more than a power plant.** It’s the foundation for a future of clean, scalable energy that meets global demand while reducing humanity’s carbon footprint. CFS will independently finance, build, own, and operate the first ARC power plant in Chesterfield County, near Richmond, Virginia — an area with a growing population, economy, and demand for energy. This relationship will prove valuable for not only the first ARC, but future ARC power plants as we continue on our path to commercialize fusion energy.

The experiments also achieved a new record for energy turnover, increasing it to 1.8 gigajoules, another vital step in demonstrating the reactor's ability to handle the immense energies involved in the fusion process.[2][3] "Elevating the triple product to tokamak levels during long plasma pulses marks another important milestone on the way toward a power-plant-capable stellarator," stated Professor Dr. Thomas Klinger, Head of Operations at W7-X.[5][6] This accomplishment was made possible through international collaboration, particularly with the U.S. Department of Energy's Oak Ridge National Laboratory, which developed a novel pellet injector for continuous refueling of the plasma.[1][6] During the record-setting experiments, plasma temperatures exceeded 30 million degrees Celsius.[1][2] Researchers also achieved a plasma pressure that reached 3% of the magnetic field pressure, bringing them closer to the 4-5% range needed for a commercial fusion reactor.[3][4] These milestones are not just incremental improvements; they represent a significant leap forward in demonstrating the feasibility of the stellarator concept for stable, long-term energy production.
