Abstract
It is known that NBI ion losses may pose a problem to the Wendelstein 7-X first wall, but the so-far utilized wall models had insufficient details for reproducing the locations and magnitude of the hot-spots. This study aims to exhaustively analyse the detailed wall loads in the reference magnetic configurations and in various plasma scenarios. The goal is to pinpoint the endangered plasma facing components and to calculate heat loads to them in preparation for the first NBI operations. This study can be used to prepare monitoring of the heat loads and paves the way to future searches of improved configurations.
