Non-destructive inspection system and non-destructive inspection method

摘要

PROBLEM TO BE SOLVED: To provide a non-destructive inspection system and a non-destructive inspection method capable of accurately detecting the amount of a peculiar portion from the position information of a peculiar portion of an object to be inspected. SOLUTION: A neutron irradiation unit 12 capable of irradiating pulsed neutrons, a neutron detector 14 capable of detecting neutrons irradiated from the neutron irradiation unit 12 and passing through an object to be inspected, and a material and neutrons of the object to be inspected. A storage unit that stores attenuation information indicating the relationship between attenuation and distance information indicating the position of a peculiar part in the inspected object according to the time change information that is the time change information of the neutron amount detected by the neutron detector 14. It is equipped with an arithmetic unit that can be calculated, and the arithmetic unit can generate information on the amount of singular parts from information based on the amount of neutrons in the time change information using distance information and attenuation information.
