Safe feed system for absorber fluid containing neutron poison, for use in rapid shut-down of nuclear reactor, comprises storage container connected to pressure vessel filled with propellant fluid via overflow line

摘要

In a feed system (2) for an absorber fluid (4) containing a neutron poison, with a storage container (6) for the fluid, the storage container is connected, via an overflow line (22), with a pressure vessel (16) filled with propellant fluid (14). Independent claims are also included for the following: (1) preparing an absorber fluid (4) under operating pressure in a storage container (6) of a feed system (2) as above, involving generating the operating pressure by heating the propellant fluid (14) in the pressure vessel (16); and (2) a nuclear power station (specifically a boiling water nuclear power station) provided with the above feed system.
