Deployment of MAGS, a comprehensive tool for magnet design and safety analysis, for quench and arc simulation of an ITER-FEAT coil

摘要

The coil system of the ITER-FEAT research tokamak stores an energy of about 40 GJ. This amount of energy has to be removed in a safe and controlled manner from the system in case of an accident. As experimental possibilities are limited, numerical models are in great demand. MAGS (MAGnet System) represents a computer code system to simulate accident scenarios of magnet systems of fusion plants. It was used in the past to investigate accident scenarios of the ITER assembly which are required for licensing questions. In this work, the MAGS code is used to perform the safety analysis for a toroidal field (TF) coil of the new ITER-FEAT design becoming necessary due to changes in the magnet system compared to the previous ITER assembly. The analysis includes quench and arc scenarios.
