METHOD FOR DETECTING MEDIUM OR LARGE LEAKS THROUGH THE EXCHANGE WALL OF A STEAM GENERATOR USING LIQUID METAL

摘要

P THE PROCESS CONSISTS OF CONTINUOUSLY MEASURING A PHYSICAL PARAMETER RELATING TO LIQUID METAL PROVIDING VAPORIZATION HEAT. COMPARE THE MEASURED VALUE OR ITS EVOLUTION OVER TIME TO ANOTHER VALUE OF THE PARAMETER OR TO ITS EVOLUTION OVER TIME, DETERMINED UNDER DIFFERENT CONDITIONS. MEASURING FOR EXAMPLE THE TEMPERATURE OUT OF EACH OF THE SECTORS OF THE STEAM GENERATOR THROUGH THERMOCOUPLES 34 OR MEASURING THE LEVELS 30, 32 OF SODIUM THANKS TO PROBES 35, 36. THE VALUES MEASURED ARE COMPARED WITH THEM OR WITH VALUES REFERENCE. LEVEL MEASUREMENTS MAY ALSO BE CARRIED OUT AT A POINT OF THE LIQUID METAL STEAM GENERATOR SUPPLY CIRCUIT 42. /P
