Nuclear power plants (NPPs) play a significant role in ensuring the energy independence for many countries, as it is one of the most powerful and clean energy sources available. On the other side, NPPs are made up of very complex cyber physical systems that if compromised can result in potentially hazardous environmental consequences. It is, therefore, important to ensure the stability and reliability of NPPs by maintaining continual control and monitoring capabilities of equipment components that run the power units. In case of an accident, a special highly resilient and survivable monitoring system is needed to measure critical parameters of the reactor’s safety subcomponents and provide mechanisms to physically assess criticality levels. In addition, the monitoring system must also maintain the decision-making policies for NPP recovery and minimal start-up sequences. In general, these issues can be …
