Abstract

Numerical analysis of the plasmas in the divertor and scrape-off layer (SOL) of a fusion engineering reactor (FER) is made by using the two-dimensional time-dependent simulation code. The equation for plasmas in the SOL and divertor regions is solved for the given particle and heat sources from the main plasma, \varGammaout and QT. For the given size of the pumping duct and the pumping speed, the necessary value of \varGammaout for the ash exhaust is discussed. Sufficient ash exhaust is possible under the condition which is consistent with the scaling law of the particle and energy confinement of the main plasma.
