Introduction  This article aims to overcome the shortcomings of commissioning techniques for reactor protection systems and improve the efficiency and quality of reactor protection system commissioning.

  Method  A set of automation commissioning tools was specifically designed for the reactor protection system of the HTR-PM. The tools which adopted advanced technology could automatically complete the commissioning of the reactor protection system, and could greatly improve the efficiency and quality of commissioning.

  Result  This article mainly elaborates on the R&D and application of the commissioning tools for the reactor protection system of HTR-PM (High-Temperature Gas-cooled Reactor—Pebble-bed Module). It introduces the R&D process, difficulties, and contents of the commissioning tools, as well as the design ideas, implementation methods, and results of automatic commissioning functions such as signal output, signal acquisition, data processing, and information display. Through the actual commissioning and application of the reactor protection system of the HTR-PM in terms of function and performance verification, these tools are able to quickly and accurately identify and solve problems during the commissioning process, demonstrating the effectiveness and usability of the tools.

  Conclusion  The results show that automatic commissioning tools can improve the efficiency and quality of reactor protection system commissioning, and enhance the reliability and safety of the reactor protection system. At the same time, further research and improvement of automatic commissioning tools are still needed to meet the different commissioning needs of the reactor protection system.
