ABSTRACT:
The present invention is directed to a boiling water reactor wherein housed within the reactor pressure vessel is the nuclear core and an upper steam dome connected to a steam outlet in the RPV. The improvement comprises a vessel disposed in the steam dome and containing a neutron poison effective for inactivating the core. This vessel is vented to the steam dome for pressurizng the poison contained therein. The vessel also is connected by a line terminating beneath the core. The line contains an actuatable valve to release the poison through the line upon its actuation. The poison, when released, flows through the line by gravity to beneath the core for mixing with the reactor coolant which passes through the core resulting in consequent inactivation thereof.
