Abstract: A nuclide transmutation device and method which enable nuclide transmutation to be performed in a small-scale device compared with large-scale devices are disclosed. The device comprises a structure, and high and low deuterium concentration units are disposed on either side of the structure so as to sandwich the structure therebetween, wherein an electrolytic solution containing heavy water is supplied to the high deuterium concentration unit and is electrolyzed to generate deuterium, thereby producing a state of high deuterium concentration near the high deuterium concentration unit side surface and placing the low deuterium concentration unit in a state of low deuterium concentration relative to the high deuterium concentration unit, causing the deuterium to penetrate through the structure from the high deuterium concentration unit toward the low deuterium concentration unit, and subjecting a substance to nuclide transmutation by reaction with the deuterium.

Abstract: A nuclear material detection device that can detect a nuclear material with high accuracy is provided. The nuclear material detection device (10) detects a nuclear material contained in an object under inspection A to be inspected. A neutron detection sensor (1) is disposed so as to oppose the object under inspection A and detects neutrons emitted from the nuclear material. The neutron detection sensor (1) can detect the two-dimensional position of the source of neutrons emitted from the nuclear material.

Abstract: Provided are a security gate system and a security gate control method capable of accurately inspecting inspection targets in a short period of time. The security gate system includes a main route 2; a mass spectrograph 3 for analyzing a sample (for example, a ticket) obtained from an inspection target (for example, a facility user at an airport, etc.) moving in the main route 2; at least one branch route 10 that is divided from the main route 2 at the downstream side of a position where the sample is obtained in the moving direction of the inspection target; gates (a first gate 5 and a second gate 6), which are provided at branch sections of the branch route 10 for switching a flow path of the inspection target; and a control apparatus 20 for performing control to switch between the gates 5 and 6 based on an analysis result of the mass spectrograph 3.

Abstract: Under the granulating section 10a for performing fluidized-bed granulation coating of powder grains, a drying section 20a for drying powder grains granulated is provided. A drying section 30a for drying the powder grains that are not sufficiently dried is provided under the drying section 20a. A product discharging section 40a for discharging a dried product is provided under the drying section 30a. A fluidized-bed forming-gas is supplied downward to upward, and granulation and dryness are continuously performed by the fluidized-bed forming-gas, and the powder grains moved from the granulating section to the drying section located immediately thereunder are pneumatic classified.
