The position of nuclear long-distance energy in the network of fossil energy and nuclear energy is shown in Figure 1. It is shown that almost all the methods of nuclear process heat discussed today involve the development of a reactor with 950 ° C and a nuclear heated one Need canned system; an exception is coal gasification with steam, which requires a special heat exchanger technology and, depending on the type of coal, possibly higher helium temperatures in the cooling gas. The individual processes differ only slightly in terms of the design of the Nuclear reactor and the canned plant as well as especially the Heat extraction, special boundary conditions with regard to pressure and gas analysis has a special method of direct reduction.
