ABSTRACT:
Apparatus for the purification of the liquid metal for cooling the core of a fast neutron reactor comprising a heat insulating envelope immersed in the reactor core and suspended from the protective slab surmounting the latter, a removable plug disposed in said slab and giving access to the upper part of the inside of the envelope and, within the latter, a cooling coil for cooling a liquid metal flow taken from the reactor core to a temperature which ensures the solidification of impurities, a filter cartridge for filtering the cooled liquid metal, a heat exchanger for the at least partial heating of the purified metal prior to its return to the reactor core and a valve for regulating the purified metal flow returned to the core, wherein it comprises a passage for returning to the upper part of the envelope purified metal from the filter cartridge, the purified metal being returned to the reactor core with the purified metal in heat exchange with the metal to be purified in a regulated flow, the regulating valve of said flow being disposed in the upper part of the envelope.
