摘要：

On the basis of the modeling experiments of hot plasma influence on the graphite and tungsten materials performed on the GOL-3 device, an analysis was made of a possibility for explosive erosion to occur under ITER disruption conditions. In this analysis, the threshold value for explosive erosion obtained in the GOL-3 experiments was taken into account. Then the volumetric energy release was calculated for a hot plasma (T=1-20 keV) reaching the target at the limit of irradiating flux close to the conditions of ITER disruption (an energy flux of up to 140 MJ/m(2)). It is shown that under such conditions, erosion can reach values much higher than those in the case of erosion under the effect of a plasma with lower temperature but with the same energy density.
