Abstract

The invention discloses a nuclear fuel burnable poison core block comprehensive size detection system which consists of a test desk, a capacitive displacement sensor arranged on a test desk support, a electric appliance control box, a foot-operated switch and a data processing system, wherein the electric appliance control box is respectively connected with the capacitive displacement sensor, thefoot-operated switch and the data processing system through respective transmission lines. The electric appliance control box includes a data conversion plate with a data conversion module and an input and output interface, a logic control plate and a power supply conversion plate respectively connected with the data conversion plate, and a transformer connected with the power supply conversion plate, wherein the logic control plate is a function control plate with acousto-optic alarm control and logic judgment control. The invention employs manual charging, automatically records, judges, counts and stores data, and prints output results. Compared with a detection using a manpower manual micrometer method, the invention has higher detection efficiency and detection quality, and resolves problems of batch detection and apportioned length assembling of core block.

Description

technical field [0001] The invention belongs to nuclear fuel measurement technology, and in particular relates to a detection system and a detection method for the comprehensive size of combustible poison pellets. Background technique [0002] Nuclear fuel combustible poison pellets are fuel element cores used in pressurized water reactors. The comprehensive size of the pellets (length, outer diameter, roundness, etc.) is an important technical indicator of the pellets. In mass production, a reasonable sampling inspection plan should be adopted , accurately measure the comprehensive size of the pellets, provide data for stack physics and thermal calculations, and have important significance for determining the use effect of fuel elements in the stack and the manufacture of pellets. In the process of pellet production, it is not only necessary to detect a large number of comprehensive dimensions of pellets, but also to feed back a large amount of statistical data and reports ...
