Detection of Fuel-Elements for the Fuel-Handling System in a High Temperature Gas-Cooled Pebble Bed Reactor

摘要

To detect the fuel elements in HTGRs, a new detection method based on the vibration signals of piping system in FHS has been developed. Based on large amounts of experimental data, a signal processing method has been proposed and the detection parameters have been optimized. The off-line and on-line detection systems based on above results have been built by virtual instrument technology. The detection system has been tested in various conditions. The experimental results show that the detection system works accurately and reliably.
