Nowadays, many fusion experiment has shorter discharge time than about 1 s, although in the future, fusion reactor will have longer time than 1 hour, and active cooling of plasma facing components must be equipped. However, heat flux study with this cooling effect treated correctly has been limited. This induces uncertainty of estimating the effect of pulse heat load such as ELM. In this work, these problem will be discussed with basic model calculation.
