Mathematical Modeling of the Cooling First Wall of the Tokamak Reactor

In the course of designing the post-ITER fusion facilities, a number of new technical and scientific problems occurred that were unknown before and necessarily have to be solved. Among these problems, one of the most important is the design of the reactor first wall, which could withstand the continuous heat fluxes coming from the fusion plasma. In this article, the mathematical model of the cooling first wall of the reactor is constructed and the numerical analysis is performed of the currently accepted first wall design of the future DEMO-FNS reactor (Fusion Neutron Source).
