Considerations for the future world economy require a substantial contribution of nuclear energy. However, a new quality of safety is necessary for the future world-wide increased use of nuclear energy, a catastrophe-free nuclear technology is demanded. Catastrophe-free means, that even in case of extreme accidents there is no release of unallowable arnounts of radioactive fission products from the reactor plant, the consequences of the accident maust be restricted to the area of the reactor plant itself. To reach this objective it can be tried either by reactor concepts with guaranteed retention and control of the consequences of a molten core inside the reactor containrnent or by reactor concepts, in which the core melt accident is excluded by natural laws in which the radioactive fission products stay inside the fuel elements in all accidents. This report treats conditions which are stringent in the lauer case. The following 6 conditions niust be fulfilled in all cases of accidents: selfacting limitation of the nuclear power production and of the fuel temperature, selfacting aller he g t removal from the core and the power plant,selfacting receipt of the barriers fuel elements, reactor pressure vessel and reactor containment, independency of the fission product barriers frorn each other.These are final conditions for the receipt of the integrity of the fuel elements and the retention of the radioactive fission products in the fuel elements. The refered requirements to realize catastrophe-free nuclear technology haue to be proved extensively for new reactor concepts. |
