DAMAGE OF ITER DIVERTOR PLATES AT PLASMA DISRUPTION
The analysis of the effect of ELMs and plasma disruptions in ITER on the divertor plates is carried out. At ELMs the divertor plates will not melt, and at plasma disruption it is expected. The transport of melt tungsten and droplet erosion are not possible because instability of Kelvin Helmholtz and instability of pulsing bumps do not develop due to the low dynamic pressure of tangential flow as the initial plasma and plasma formed from the erosion products. The most serious erosion can be the formation of cracks and brittle destruction. The evaporation from the surface will be an additional reason of mass loss.
