Calculation of eddy currents on some passive structures of the NET tokamakFunded under: EAEC-FUSION 12C
Of major importance during the design phase of a fusion machine is the investigation of plasma disruption effects such as the eddy currents induced on the machine passive structures. The eddy currents on some important passive structures (local limiter, inner and outer blanket, first wall) of the NET conceptual tokamak machine are calculated by means of an electromagnetic computer code (MSC/EMAS). The plasma is considered as a current driving loop (or a set of current driving loops) interacting with the external passive circuits through their mutual inductances. The plasma disruptions are simulated either by an exponential plasma current quench with the plasma at rest, or by a linear fast vertical plasma displacement with a velocity of 2.4 m/30 ms followed by a current quench. The stresses due to the eddy currents are also investigated.
