A non-destructive inspection system includes a non-destructive inspection apparatus and a management apparatus. The non-destructive inspection apparatus includes: a neutron emission unit capable of emitting a neutron beam; a gamma-ray detector capable of detecting a gamma ray; an apparatus case covering the neutron emission unit and the gamma-ray detector and including an opening; an outer shutter configured to open and close the opening; dose monitors each provided on the apparatus case and configured to detect a radioactive dose; an apparatus communication unit capable of transmitting apparatus information including the detected radioactive dose to the management apparatus and capable of receiving inspection permission information from the management apparatus; and an apparatus control unit configured to open the outer shutter and allows emission of the neutron beam from the neutron emission unit upon acquisition of the inspection permission information.

Non-destructive inspection device and non- destructive inspection system

A non-destructive inspection system includes: a neutron emission unit capable of emitting neutrons having a first neutron dose; a neutron detection unit capable of detecting a second neutron dose of neutrons scattered inside an inspection object A by the emission of the neutrons from the neutron emission unit; a gamma-ray detection unit capable of detecting a gamma dose of gamma rays released from the inspection object A by the emission of the neutrons from the neutron emission unit; and an analysis unit configured to calculate a content of a predetermined substance based on the gamma dose and correct the content of the predetermined substance based on the first neutron dose and the second neutron dose.

Nondestructive inspection system

A non-destructive inspection systemincludes a neutron detecting unitand an arithmetic unit. The neutron detecting unitincludes a collimatorand a neutron detectorintegrated together. The collimatorhas a wall defining a through passage P. The wall is made from a material that absorbs neutrons produced via an inspection object. The neutron detectoris capable of detecting neutrons that have passed through the collimator. The arithmetic unitgenerates information on a position and composition of the inspection object, based on information on the neutrons detected by the neutron detector, positional information indicating the position of the neutron detecting unit, and posture information indicating the posture of the neutron detecting unit. The positional information and the posture information are detected by a position and posture detecting unit
