Wall temperatures of a reactor vessel (10) are monitored by arranging an optical fibre (20) in thermal contact with the wall (16) and employing an optical time domain reflectometry system (28) to monitor the respective temperatures at different points along the fibre. Such a monitoring method can be cheaper and more reliable than comparable prior art methods. An alarm (29) may be triggered automatically when hot spots are detected.

On surveille les températures des parois d'une cuve (10) de réacteur en disposant une fibre optique (20) en contact thermique avec la paroi (16) et en utilisant un système de réflectométrie temporelle optique (28), ce qui permet de surveiller les températures respectives en différents points de cette fibre. Ce procédé de surveillance peut se révéler moins coûteux et plus fiable que les procédés actuels comparables. Une alarme (29) peut s'enclencher automatiquement en cas de détection de points chauds.
