Embodiment Construction

[0015]The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0016]The present invention provides a score-measured sample method of a zero power experiment device, and the experimental element is designed to be inserted with a fuel element, and the experimental element can be inserted into the core, and the sample sampling device provided by the present invention prior to the opening. take out. The experimental element is connected to the sample sampling device, and the launch of the experimental element is irradiated and simultaneously monitors the power level of the reactor through the power supervision device; the irradiation is closed, and the experimental element is pulled out from the core through the sample sampling device. And deliver to the position away from the core, then take out the experimental components from the resort, and measure the detection tab.

[0017]For power supervision equipment, a set of threshold fis...

Abstract

The invention relates to a method and device for energy spectrum measurement and sampling of a zero-power experimental device. The device includes a slide rail, and a roller movable along the slide rail is provided on the slide rail, and experimental components are connected with the roller; One end of the rail is located above the core, and the other end is away from the core. The rollers are connected to the motor located at the end of the slide rail away from the core through the connecting rope, and the rotation of the motor drives the rollers to move in the slideway of the slide rail. The invention can save the waiting time for shutting down and sampling, effectively improve the counting rate of activity measurement of irradiated samples, and avoid the damage of decay rays during sampling.

Description

Technical field[0001]The present invention belongs to neutron energy spectrum measurement techniques, and more particularly to a spectrum measurement sampling method and apparatus for a zero power experimental device.Background technique[0002]The accelerator drives the secondary system (ADS, Accelerator Driven Sub-critical System), producing a high-energy strong-active protruding target (such as lead, etc.) generated by the accelerator, producing a cracked neutron driving and maintaining a secondary pile operation It has inherent security. The neutron energy of the ADS system is high, the flux is large, the energy distribution is wide, and the evernel life is strong, which can significantly reduce the radioactivity of nuclear waste, and realize the least treatment of nuclear waste, and can also output energy, improve The utilization rate of nuclear resources is recognized as the most effective means of nuclear waste treatment. At present, there is no precedent for the engineering ap...
