Abstract

PURPOSE:To precisely measure an interval between fuel rods, by a method wherein a moving amount and a moving direction of a sensing probe, which is inserted between the fuel rods and is caused to move from the one fuel rod until it makes contact with the other fuel rod, are measured. CONSTITUTION:Fuel aggregate 11 are surrounded in a coupling part 23, and sensing probe 5 are designated to be individually positioned between fuel rods 4. With a motor 21 moved in one-way, scanning shafts 13 and 14 are moved, and each time a destortion detector 10, corresponding to the sensing probe 5, detects the individual deformation, a value of a scanning amount measuring device 26 is individually stored in a memory. With a motor moved in the opposite direction, the scanning shafts 13 and 14 are moved in the reverse direction. The current value of the scanning amount measuring device 26 is read-in each time the contact of the deformation detector 10, corresponding to each sensing probe 5, is made with the fuel rod is detected, and an interval between the respective fuel rods is detected by substracting the value of the device 26 from the corresponding value stored in the memory unit.
