HEAT-EXCHANGER WITH EMERGENCY COOLING ARRANGEMENTS AND FAST NUCLEAR REACTOR HAVING SUCH A HEAT-EXCHANGER

摘要

The invention relates to a heat exchanger incorporating emergency cooling means, as well as to a fast neutron nuclear reactor incorporating such an exchanger. The emergency cooling means comprise an inlet pipe issuing into the secondary fluid inlet chamber and an outlet pipe issuing into the secondary fluid outlet chamber. The inlet pipe issues into a distributing ramp positioned below the lower tue plate and the outlet pipe issues into a collecting ramp positioned above the upper tube plate. The two ramps are positioned below the intake and discharge pipes for the secondary fluid.
