Digital Rod Control System (NuRIC), referred to as the "Rod Control System", is independently developed by SNPAS. The system uses FPGA+MCU technology to develop the core control-rod current regulation cards and builds the rod control logic using the NuCON platform. Based on these core components, it realizes complete monitoring and control functions for the control rods. The system is equipped with dedicated test devices for laboratory or on-site testing.

Digital Rod Position Indication System (NuRIC), referred to as the "Rod Position System", is independently developed by SNPAS. The system is used for control-rod position detection and implements rod position indication and alarm functions via the NuCON-based logic control system. It also provides control-rod drop-time measurement capability. The system is equipped with a complete set of test devices for laboratory or on-site testing.
