Heat-pipes-based first wall

Feasibilities of heat pipes application for the heat transfer out of plasma facing components in test and power fusion reactors are discussed. Based on the space technology and practice the “hot” ITER first wall with liquid metal and water heat pipes are proposed in two options: heat-pipes and vapor-chamber options. Other high heat loading in-vessel elements such as divertor target and limiter can be provided by effective and reliable heat pipe cooling systems.
