Abstract

L'invention concerne le coeur d'un réacteur nucléaire. Cette structure, soumise à une température haute et variable, est surveillée par deux transducteurs de température, qui présentent des capsules 1 emplies de gaz et contenant chacune une jonction chaude 5 de thermocouple, fixée à la face interne d'une paroi extrême exposée à l'environnement de la structure. Une paroi extrême d'un transducteur est un diaphragme 2 dont les perturbations de température correspondent à celles de la surface de la structure. La paroi extrême du 2** e transducteur est un cylindre massif dont les perturbations thermiques correspondent à celles atténuées, de la masse de la structure. Application : structures du coeur de surrégénérateurs à neutrons rapides refroidis par un métal liquide.The invention relates to the core of a nuclear reactor. This structure, subjected to a high and variable temperature, is monitored by two temperature transducers, which present capsules 1 filled with gas and each containing a hot junction 5 of thermocouple, fixed to the internal face of an end wall exposed to the temperature. environment of the structure. One end wall of a transducer is a diaphragm 2, the temperature disturbances of which correspond to those of the surface of the structure. The end wall of the 2 ** nd transducer is a massive cylinder whose thermal disturbances correspond to those attenuated, of the mass of the structure. Application: core structures of fast neutron breeders cooled by a liquid metal.
