<p>1. A safety cooling installation for a water reactor of a nuclear power station, comprising a reservoir (1) for storing a cooling liquid (2), outside a containment (6) enclosing the circuit of the reactor, a pump (3) arranged at least for aspirating the liquid (2) from the reservoir (1) and for discharging the same into said circuit, an ejector (9) arranged for recovering the liquid (2) and the water from the reactor in the event of a break in the circuit of the latter said liquid (2) has at least passed into the reactor's circuit, and transport the cooling liquid (2) and the water to the pump (3), the pipe-lines (11, 12) and circuits (4, 5) connecting the pump (3) and ejector (9), and the containment (6) and the reservoir (1), and valve means for permitting or stopping the discharge of cooling liquid (2) and water which pass through the pipe-lines (11-12) and the conduits (4, 5), characterized in that the ejector (9) is situated in the lower part of the containment (6) and is arranged for directly recovering the liquid (2) and the water from the reactor in the event of a break in the circuit of the reactor.</p> |
