Safety systems and structural aspects of superconducting magnets for fusion power reactors
Abstract
Existing large superconducting magnet systems have operated safely and reliably, however, future superconducting magnet systems for fusion power reactors will represent a very large extrapolation over existing systems in terms of size, stored energy, effects of pulse force loading (Tokamaks), and operating time. The present paper deals with potential safety systems for such future magnet systems. Owing to current and voltage limitations (which could lead to electrical breakdown), energy removal systems are seen to be impractical for dumping significant amounts of energy external to the magnet. Since temperature inhomogeneities may cause electrical breakdown and structural damage, some type of temperature equalization system appears necessary to minimize inhomogeneities if energy is dumped internally during a quench or other accident situation. Also, large detection nets should be developed to detect potential hot spots before they can damage the magnet.
