Title:
A nuclear material detection device and a nuclear material detecting method
Document Type and Number:
Japanese Patent JP6164748
Kind Code:
B2
Abstract:
A nuclear material within a container is to be detected. Included are: a neutron source for generating neutrons emitted toward the container; a detection section capable of detecting neutrons including primary neutrons emitted from the neutron source and secondary neutrons generated through a nuclear fission reaction of the nuclear material; and a processing section for performing a reactor noise analysis process based on data obtained through detecting of neutrons by the detection section. The neutron source generates neutrons in a pulsatile manner. The processing section performs the reactor noise analysis process based on data obtained by excluding, from time series data obtained through detecting of neutrons by the detection section, data of a time range including a generation time of the neutrons generated by the neutron source in the pulsatile manner.
