Flux Thimble Thermocouple Assemblies

Main description

Framatome’s Flux Thimble Thermocouple Assemblies feature proven seal and connector design improvements that translate into improved safety and lower costs for plant operators. The Flux Thimble Thermocouple Assembly integrates core exit thermocouples with the thimble tubes used in the moveable in-core monitoring system. While the outer tube is designed to withstand system pressure and provides the first pressure boundary to the reactor coolant, the thicker inner tube provides the pressure boundary of record, meeting ASME over-pressure design margin requirements.
