Description
The pebble-bed High Temperature Gas-cooled Reactor (HTGR) can work continuously with high reliability. It has been listed in the national 11th five-year plan. The fuels handling system is an important part of HTGR. The fuel balls inspecting system is significant to the operation validity of fuels handling system. An inspecting system with outside fixed sensors is designed. The sensor can be installed or removed without destruction of the ball-passing pipes. This makes the handling system safer and easier to be maintained. The direct digital synthesis (DDS), ultrahigh speed phase/frequency discriminator and amplitude detectors are used to inspect the ball-passing signals. Experiments show that the system can inspect the discrete and continuous ball-pass accurately when the speed is between 0.1 m/s and 10 m/s. (authors)
