Some insights on issues related to specifics of the use of probability, risk, uncertainty and logic in PRA studies
The paper presents the main results of the insights to a gas cooled reactor from the perspective of the following notions: probability, uncertainty, entropy and risk. Some results of the ongoing comparisons between the insights obtained from three models are presented. The approaches consider the PBMR nuclear power plant (NPP) as a thermodynamic installation and as a hierarchical system with or without considering the information exchange between its various levels. The results indicate on the convergence on some conclusions and approaches adopted for this type of reactor.
