| abstract | (57) [Abstract] [Purpose] The present invention makes it possible to measure the gaps of fuel rods and the like simply and with high accuracy, and to ensure reliable and short time regardless of the radial cross-sectional shape of the nuclear fuel assembly. It is an object of the present invention to provide a measuring method and a measuring device for a gap of a fuel rod or the like that can measure and inspect the gap of the fuel rod or the like. A gap measuring device for fuel rods and the like according to the present invention comprises a fuel assembly in which a plurality of fuel rods and water rods are bundled in a lattice with spacers, and a gas atmosphere chamber 15 filled with a specific gas such as CF 4. A measuring device 11 installed inside the measuring device 11 utilizing a nuclear magnetic resonance phenomenon, a static magnetic field coil for forming a stationary magnetic field, a gradient magnetic field generating coil for forming a gradient magnetic field, and a high frequency magnetic field are applied to the measuring device 11. The control means 12 controls each magnetic field with a high frequency coil for detecting a nuclear magnetic resonance signal, and the data processing means 13 for inputting a nuclear magnetic resonance signal detected by the high frequency coil to perform data processing. The processing means 13 is configured to process the gas distribution in the fuel assembly as a cross-sectional image of the fuel assembly to measure the gap between the fuel rods and the gap between the fuel rod and the water rod. Than it is. |
