High-level waste bin nondestructive detector control system and method

Abstract

The invention discloses a high-level waste bin nondestructive detector control system and method, and the system is characterized in that a human-computer interface touch screen is connected with a first switch through the Ethernet, the first switch is connected with a main controller and an auxiliary controller through the Ethernet, the main controller is connected with the auxiliary controller through the Ethernet, the main controller and the auxiliary controller are connected with a second switch through an industrial bus, the second switch is connected with a main I / O module and an auxiliary I / O module through an industrial bus, the main I / O module and the auxiliary I / O module are connected with a third switch through an industrial bus, the third switch is connected with a plurality of drivers in series through an industrial bus. A safety special programmable logic gate array is connected with each driver through hard wiring, and each driver is connected with one servo motor through a cable. The controller redundancy, the I / O module redundancy and the safety function redundancy are designed for the high-level waste bin nondestructive detector, and the reliability and the safety of the nondestructive detector are further enhanced while the detection efficiency of the nondestructive detector is improved.

Description

technical field [0001] The invention relates to the field of control of non-destructive detectors for high-level radioactive waste barrels in spent fuel reprocessing plants, and in particular to a control system and method for non-destructive detectors for high-level radioactive waste barrels. Background technique [0002] The radioactive waste generated by nuclear facilities should be collected, pretreated, treated, and prepared to form sealed packaging waste packages, such as waste barrels or waste steel boxes, and then transported to the disposal site for disposal after storage. The waste generating unit needs to fill in the waste total activity, main radionuclides and their activity concentrations and other information in the waste bin file. Since waste bins are usually not sampled and analyzed after they are produced, nondestructive testing methods can only be used to measure waste bins to obtain nuclide and activity information. Therefore, the waste bin non-destructiv...

Problems solved by technology

[0003] The non-destructive testing room of the waste barrel is in a high radioactive environment. The existing domestic high-level waste barrel non-destructive testing instrument lacks or only has a single redundant design. When the waste barrel is in the non-destructive testing room, the staff cannot enter the testing room. Therefore, for high-level radioactive waste The reliability and safety design of the barrel non-destructive testing instrument should have higher requirements. At the same time, it is also necessary to take into account the high efficiency of the non-destructive testing process of high-level radioactive waste barrels, shorten the detection time, and improve the detection efficiency.
