Description

The specific operating conditions of thermocouples in nuclear reactors have provided an incentive for further advances in high temperature thermocouple applications and performance. This work covers the manufacture and improvement of existing alloys, the technology of clad thermocouples, calibration drift during heat treatment, resistance to thermal shock and the compatibility of insulating materials with thermo-electric alloys. The results lead to specifying improved operating conditions for thermocouples in nuclear reactor media (pressurized water, sodium, uranium oxide)

Abstract (French)

Les conditions particulieres d'utilisation des thermocouples dans les reacteurs nucleaires nous ont conduit a accomplir de nouveaux progres dans la mise en oeuvre et les proprietes des thermocouples a hautes temperatures. L'etude porte sur la realisation et l'amelioration des alliages utilises, la technologie des thermocouples gaines, les derives d'etalonnage au cours des traitements thermiques, la resistance aux chocs thermiques et la compatibilite des isolants avec les alliages thermo-electriques
