The aim of this study is to know whether the carbon can enter the narrow gaps between tiles and with which energy. Due to its radioactivity, the tritium deposition is also of high interest. The global penetration of the two hydrogen species into the gap is in the order of the gap width (~0.5 mm) and their own contribution on the total heat flux to the gap is estimated. The main impurity penetrates into the gap in between 50 to 70% of the total plasma deposition in the gap but with a power deposited representing less than 1% of the total deposited power.
