G21B FUSION REACTORS
Introduced: September 1968
Classification Context
- Section:
- PHYSICS
- Class:
- NUCLEAR PHYSICS; NUCLEAR ENGINEERING
- Subclass:
- FUSION REACTORS
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.
Additional Content
Glossary
Confinement Controlled compression of fusion nuclei to overcome their electrostatic repulsion. Fusion Combination of two or more nuclei to form a heavier nucleus, a by-product of which is the release of energy. Thermonuclear Relating to fusion at high temperatures.
Limiting references
