For the Demo reactor, the blanket design is one of the most important issue and the analysis of the surface heat load on the first wall for that design is essential. The neutron load, radiation load and the ion heat load are the main contributing factor of the first wall heat load. In this conference, the ion heat load is mainly considered. The analysis of the relationships between the form of the Demo first wall module and the ion heat load will be presented.
