PROBLEM TO BE SOLVED: To provide a system which enables ECP measurements in the core of a pressurized water reactor (PWR), without requiring extensive renovation work. SOLUTION: The ECP measurement system for PWR, which measures ECPs in a core section in the PWR equipped with sheath tubes for inserting thermocouples which are placed so as to reach the core section from outside a reactor vessel and have bending sections and pillars for supporting thermocouple outlet pipes, which include the sheath tubes for inserting the thermocouples upstream from the branching of the sheath tubes for inserting the thermocouples keeps ECP sensors for the PWR inserted thereinto and are mounted on sheath tubes for inserting thermocouples at positions adjacent to the pillars for supporting the thermocouple outlet pipes, after the sheath tubes have come out of them and branched off.
