✦ Synopsis

The paper presents some preliminary results of diagnostic analysis of the simulated primary circuit of the THTR-300 nuclear power plant, based on the fuzzy sets theory. Two methods are used: the solution of the fuzzy relational equations and its extension to fuzzy logic. The first stage of the diagnostic system is the identification of the plant in the sense of fuzzy relations and the second stage is the failure or disturbance recognition. According to the fuzzy logic, lower and upper bounds of the failure vectors are obtained. Such an expert system can supply the operator in a correct recognition of the current state of the complex plant.
