Our Nu-series products are China's first nuclear power instrumentation and control (I&C) systems with independent intellectual property rights and qualification for international market access.

NuPAC

NuPAC (Reactor Protection System Platform) is a nuclear power plant (NPP) protection system jointly developed by the SPIC subsidiary State Nuclear Power Automation System Engineering Co. (SNPAS) and the United States' leading companies. As a key NPP digital I&C system, it has the ability to answer the NPP emergencies such as earthquake, tsunami and other natural disasters immediately and to shut down the reactor safely. It serves as the bodyguard of nuclear power plants. NuPAC is the world's first case where the Field Programmable Gate Arrays (FPGA) technology is applied in commercial NPPs, and the first nuclear grade NPP I&C product that has obtained the administrative permission of nuclear safety regulatory authorities in both China and the United States.

NuCON

NuCON (Nuclear Power Plant Control System Platform) is an NPP control system independently developed by SNPAS. As a key system enabling control and monitoring during normal operation, it is crucial to ensure the reliable, stable and economical operation of an NPP.

NuBAC

NuBAC (Diverse Actuation System Platform) is a diverse actuation system in an NPP. A backup system for the reactor protection system, NuBAC is an important component to improve the defense in depth of an NPP.

NuSIM

NuSIM (Full-scope Simulator) is a trademark for full scope simulators. Independently developed by SNPAS, NuSIM is able to simulate normal operations and emergencies, whereby reactor operators receive training and apply for licenses.

NuRAD

NuRAD (Radiation Monitoring System Equipment) is an NPP radiation monitoring system independently developed by SNPAS. It monitors the level of radioactivity in the plant processes, discharges, airborne materials and adjacent areas, and feeds the radiation monitoring data to the plant control and reactor protection systems to ensure the safety of both human and the plant.

NuRIC

NuRIC (Rod Control and Rod Position Indication System Equipment) is a control rod position indication system independently developed by SNPAS. It controls the control rod drive mechanism, indicates the position of the control rods and supplies power to the drive mechanism, so as to control and allocate the output power of the reactor.

NuTEC

NuTEC (Nuclear Power Plant Special and Seismic Monitoring System Equipment) is an NPP special monitoring and seismic monitoring system. Independently developed by SNPAS, it is able to monitor the vibration of the reactor coolant pump and the cooling fans of the control rod drive mechanism, as well as seismic activities.

NuNIS

NuNIS (In-core Instrumentation/Ex-core Nuclear Instrumentation) is an in-core and ex-core instrumentation system jointly developed by SNPAS and the affiliates of China National Nuclear Corporation, capable of in-core and ex-core neutron fluence rate measuring and post-accident monitoring.
