- Summary
- Existing superconducting (SC) systems are shown to be inadequate for predicting successful performance of fusion magnets, since they have simpler geometry, much smaller size and simpler safety systems, less complex loading conditions and cyclical variations in loads, and are not exposed to radiation. Even so, a number of mechanical and electrical failures have occurred in existing magnet systems. Using the UWMAK and various EPR SC magnet designs as starting points, a number of potential safety and reliability problems are analyzed for future Tokamak TF coil systems. The voltage withstand capability of TF coils appears to be only a few hundred volts during quenches because of release of H/sub 2/ from organic glues and insulators to form Penning mixtures with helium, ionization of He by gamma rays, and use of equipotential magnet structures.
