  • Monitoring temperature within a vessel
    Patent number: 4681729
    Abstract: A vessel for the storage and monitoring of nuclear fuel materials incorporates a device (12) within its interior for providing an externally detectable signal indicating whether any temperature rise has occurred. The device (12) comprises a magnet (32) attracted towards a boundary wall (11) of the vessel and maintained in that position by a temperature-sensitive element such as a thermal link (38). The magnet (32) is subjected to an oppositely directed force by a spring (30), which is effective to drive the magnet (32) away from the wall (11) in the event of a substantial temperature rise within the vessel thereby producing an externally detectable change in magnetic flux.
