[en] Following the development work of the THTR reactor as a demonstration plant near competition and four year operation of the AVR reactor at a temperature of 950⁰C, it can be confirmed that nuclear process heat for processes like steam reforming of methane or coal gasification can be produced. The processes have been tested in large experiments in the last years. Some main technical options and additional questions of the licensing procedure are discussed. Finally, some aspects essential for the HTR, especially the question of safety, are pointed out. (AF)
