ABSTRACT:
A system for recharging fuel assemblies of a nuclear reactor, comprising a hermetically sealed chamber on whose bottom there is placed a movable platform of a recharging machine which charges the reactor with new fuel assemblies, removes spent fuel assemblies from the reactor, and transports spent fuel assemblies from the reactor to a place of storage, as well as new fuel assemblies from the place of storage to the reactor. In the bottom of the hermetically sealed chamber there are provided channels through which it communicates with an intermediary distribution chamber arranged in the reactor vessel and the places for storing spent and new fuel assemblies. Between the channels of the reactor vessel and the channel of the container for storing spent fuel assemblies, i.e. on the path along which spent fuel assemblies are transported, in the bottom of the hermetically sealed chamber there is provided a jut, whereupon there is placed a series of movably interconnected cars with overhead covers between adjoining cars which are moved into and out of the hermetically sealed chamber through a hermetically sealed hatch.
