In the event of abnormal accident conditions such as earthquakes or tsunamis at a nuclear power plant, it ensures safe reactor shutdown and unit safety.

The NuPAC platform is a new-generation reactor protection system platform based on field-programmable gate array (FPGA) technology. It adopts a distributed hardware architecture based on FPGA both functionally and physically, replacing microprocessor- and software-based solutions by hardware-implementing software functions, effectively defending against viruses and cyberattacks. SNPAS holds full independent intellectual property rights. It is the first nuclear power plant reactor protection system platform to receive administrative licensing from the nuclear safety regulatory authorities of both China and the United States.
