Standby safety injection system for nuclear reactor plants

摘要

A multiple liquid standby safety injection system for nuclear fission reactor plants comprising means for injecting supplemental coolant water into the nuclear reactor pressure vessel to cool the fuel core and means for injecting a water solution of a neutron absorbing compound into the nuclear reactor pressure vessel about the fuel core to diminish the fission reaction. The coolant water and solution of neutron absorbent each comprise individual systems (20),(40) and are conveyed from their respective supply container (22),(44) by means of pressurized propelling gas (28). The individual standby safety injection systems for coolant water and solution are integrated with means (70) for transferring propelling gas from one supply container to the other to enhance the source and available volume of liquid propelling gas for either system by drawing from the other.
