On October 11, 2023, the U.S. Nuclear Regulatory Commission (NRC) held the first of a series of three public meetings to share the staff’s progress and seek public input on the preliminary proposed rule language, preliminary draft guidance (NUREG-1556, Volume 22), and specific topics of the proposed rule that would form the regulatory framework under 10 CFR Part 30 for fusion systems.
Magnetic confinement: Plasma is heated to 100 million °C or more, then squeezed and held in place by strong magnetic fields, allowing many fusion reactions to occur. (Example: tokamaks, stellarators)
Inertial confinement: Tiny fuel pellets are struck by powerful lasers. The outer layer explodes outward, compressing the core to fusion conditions for a few nanoseconds, producing a brief but intense pulse of energy from each pellet. (Example: National Ignition Facility)
Hybrid systems: Combine compression (e.g., from lasers, plasma pistons, or mechanical impact) with moderate magnetic fields to reduce energy losses and improve confinement.
Electrostatic fusion: Uses high electric potentials to accelerate ions toward a central reaction zone, causing them to collide at high energies and fuse. The ions are guided and confined by electric fields rather than magnets, creating a compact environment for fusion reactions.
