Abstract: 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.

Keywords: uncertainty; gas cooled thermal reactors; risk; entropy; pebble bed module reactors; PBMR; nuclear reactors; probability; nuclear power plants; nuclear energy; thermodynamics; probabilistic risk assessment; PRA.
