Abstract
Efficient heat removal from the controlled thermonuclear reactor depends on the development of several technologies. Among these are the advanced low activation materials employed to build the reactor, type of fuel used to produce fusion reactions, and choice of coolants utilized to remove large heat and neutron fluxes from the wall of the reactor chamber. Significant efforts are now being made to develop helium and liquid metal cooled wall blanket modules which incorporate low activation materials, solid and liquid tritium breeders, and high thermal performance heat removal schemes. Some of these technologies will be tested in the next generation tokamak machine and possibly employed in a demonstration fusion power plant. The current fusion technology is, however, not sufficiently mature to build a reliable, safe and efficient energy producing power plant. Figs 3, Refs 49.
