This lecture describes the fundamentals of reactor safety for both the operation and the decommissioning of nuclear power plants. The first part will be focused on reactor safety issues important for the operation of a NPP:

• Safety fundamentals as defense in depth, multi-barrier concepts
• Operational modes of nuclear power plants
• Main components for heat removal, safety systems of selected NPP designs
• Thermal characterization of the core and plant under normal operation conditions
• Accident analysis in nuclear power plants- initiation, methods of evaluations and safety implications

The second part of this lecture will be devoted to explain the neutron physical, radiation protection and safety aspects to be considered for the safe and economical decommissioning of nuclear power plants:

• Life cycle of a nuclear power plant and main strategies and challenges in the NPP decommissioning
• Physical processes responsible for the activation of reactor components during the operation of a nuclear power plant
• Radioactive waste generation in the core, classification and radiological relevance
• Waste classification, minimization methods and intermediate and final disposal
• Risk analysis and prevention, radiation protection issues and the regulatory framework for decommissioning
• Computational methods for the estimation of nuclei inventories, activation and dose rates of reactor components
