The safety of the HTR 500

Comprehensive construction and operating experience is available in the high-temperature reactors constructed by the BBC group, the AVR and the THTR 300 MW, being in its commissioning phase. The main objective pursued in the planning and design of the HTR 500 was to create a marketable and commercial plant, maintaining at the same time high safety standards corresponding to the current state-of-the-art. Thus full use is made of the system-specific safety characteristics of the HTR. In addition, the great number of probabilistic analyses likewise confirming the extremely low risk of the HTR have been used as a basis of the HTR 500 safety concept. (orig./HP)
