Temperature Excursions during Loss of Magnet Coolant Accidents with Thermalization of Energy of Large Superconducting Solenoids
Present progress in plasma research has been promising to the point that several groups have started to study technological problems (including safety issues) of controlled thermonuclear reactors (CTR) , in particular Tokamaks. Similar conceptual design studies have also been carried out for inductive energy storage systems. The components and systems to be developed will include large superconducting magnets, which have been investigated for both CTR and advanced inductive storage systems. Along with the evolution of conceptual design studies , safety investigations have been conducted which address anomalous operating conditions of the superconducting solenoids. Large amounts of energy are stored in the various CTR magnets (approaching energies of 100 GJ). If these energies were to be released in an uncontrolled fashion, considerable damage might occur as a consequence of some unfavorable event (e.g., earthquake with coolant and control system failure).
