Abstract

The present study addresses the uncertainties that affect the recently performed predictions of beryllium (Be) erosion and migration in ITER using the Monte-Carlo code ERO2.0. The focus of the study is a D–T baseline discharge with fusion power gain Q=10, scrape-off layer (SOL) input power P_SOL=100MW, toroidal plasma current I_p=15MA, and central toroidal field B_t=5.3T. The parameter studies used to investigate uncertainties include variations of the radial extrapolation of plasma parameters in the far-SOL (scan A), the assumptions on impact angle distributions (scan B) and the anomalous transport of eroded Be (scan C). Variations by factors ∼3, ∼18 and ∼2 for scans A, B and C, respectively, are found.
