A proposal of safety indicators aggregation to assess the safety management effectiveness of nuclear power plants

This work develops an aggregation of proactive and reactive safety indicators in order to evaluate the effectiveness of the nuclear power plants safety management and to detect, in the early stages, signs of degradation of processes or activities used to establish, maintain and assure the safety conditions. The aggregation integrates indicators of the usual processes and is based in the manner the management activities are developed in the last decades, that is: Planning, Doing, Checking and Acting - known as PDCA cycle –, being applicable to integrated or dedicated safety management systems.
