Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

Several fault scenarios for electrical failures in the Poloidal Field (PF) magnet system are investigated involving shorts and faults with constant applied voltage at the coil terminals. A simplified model of the Compact Ignition Tokamak (CIT) is used to examine the load conditions for the PF and the Toroidal Field (TF) coils resulting from these fault scenarios. It is concluded that shorts do not pose large risks for the PF coils. Also, the type of plasma disruption has little impact on the net forces on the PF and the TF coils. However, the out-of-plane loads at the inner corner of the TF coils can increase substantially for a wide range of scenarios, and this effect can even be stronger depending on the terminal constraints on the internal PF coils.
