Abstract
In order to ensure the cooling of the support ferrule of a vessel, such as the cylindrical internal vessel (14) of a fast neutron nuclear reactor, between said ferrule and an internal wall (20) containing a liquid metal at high temperature is placed a thermal protection apparatus (29). The latter comprises sealed collecting tanks (30) supplied with relatively cold, pressurized liquid metal by means of pipes (32), connected e.g. to the reactor bearing structure (16). This liquid metal is sprayed onto the ferrule by sprayers formed in the collecting tanks. On the side turned towards the wall (20), said tanks support elements (38) of a passive thermal protection structure.
