Design of Robot System for Grinding the End of Reactor Core in Heavy Water Reactor Nuclear Power Plant

The operation space for grinding the end of reactor core is very narrow in heavy water reactor nuclear power plant. The traditional manual grinding method are low efficiency, high radiation dose and poor grinding effect. This paper designed a teleoperation robot system for grinding the end of reactor core. The robot operates in a linear Delta configuration at the slave end. The robot system integrates irradiation camera and surface detection sensor which can provide compact configuration, real-time monitoring, precise positioning and good overall results. This design greatly reduces radiation risk and provides a safe and reliable automation system solution for grinding tasks.
