Framework of Online Support System for Nuclear Power Plant Accident Management

Compared to other energy sources, nuclear power plants (NPPs) can provide clean and reliable electricity with relatively low operating costs. The NPPs are also associated with severe accidents, which are extremely rare. But once they occur, they put immense pressure on the accident management team and may cause great social and environmental impact. In this paper, we report on the ongoing development of an online support system for NPP accident management. This system combined accident diagnosis and online simulation to assess the damage state of NPP, predict possible accident progressions, and evaluate the available actions and their consequences. The system can be equipped in the Technical Support Center (TSC) or the emergency command center (ECC), which can effectively use the data from NPP and communicate with the main control room MCR and other staff immediately.
