Abstract
The transfer cupboard (1) comprises a solid body (2) made of a radiation-absorbing material, in which is provided an axially directed receptacle (3) for receiving the assembly (4). The cupboard (1) comprises at least one circuit (15) for cooling the assembly (4) by gas and integrated in the body (2) of the cupboard (1). The cooling circuit comprises at least one main axially directed gas-circulating channel (16) formed in the body (2) of the cupboard, at least one device (18) for the circulation of gas in the cooling circuit (15), and at least one device (17) for purifying the circulating gas, which are arranged in the vicinity of one end of the main channel (16). Two secondary channels (20, 21) formed in the body (2) of the cupboard make it possible to connect each of the ends of the main channel (16) to a corresponding end of the receptacle (3) for the fuel assembly (4), by which the cooling circuit is closed again.
