G21B FUSION REACTORS (uncontrolled reactors G21J)
Introduced: September 1968
Description
G21B covers controlled nuclear fusion reactors and associated systems for energy production. This includes reactor designs (inertial confinement, magnetic confinement, and alternative approaches), plasma generation and containment technologies, fuel handling and breeding systems, and reactor components such as magnets, vacuum vessels, and cooling systems. The classification encompasses both experimental fusion facilities and commercial power generation concepts, including supporting technologies for achieving and maintaining the conditions necessary for sustained fusion reactions.
