SAFETY ANALYSIS OF THE SUPERCONDUCTING MAGNET SYSTEM OF A NEXT-GENERATION TOKAMAK

A preliminary safety analysis of the superconducting magnet system of a 'next generation' tokamak is performed. Such tokamaks must satisfy n uclear class safety standards to permit their operation. Designs are n ot sufficiently advanced to permit the full safety case to be made. Ho wever scoping calculations of the form presented here enable potential problems to be identified or eliminated. With a number of constraints on the design it is shown that 'passive' safety could be achieved in such a magnet system i.e. the magnets can not cause failure in adjacen t nuclear components.
