【 摘 要 】

The performance level of instrumentation control system of nuclear power plant has great influence on the safety and reliability of nuclear power units. Rod control system (RGL) is one of the main control systems of PWR nuclear power plants. In the upstream phase of nuclear power plant overhaul, the RGL rod position channel performance re-evaluation test is the key test of the rod control system. The purpose is to collect the command rod position of the control rod during the rod lifting and inserting period to measure the rod position change. Then calculate the deviation, and then judge whether it is qualified according to certain rules. In this paper, a test system for RGL rod channel performance re-evaluation test is designed, which can automatically calculate the measurement information of all rod positions and automatically determine whether the rod position is out of tolerance. Ensure that the control rods are available during operation.
