The purpose of the research is developing mathematical models of the heat-carrier’s water-chemical mode at the first circuit VVER-1000 and their software implementation. A key aspect of the work is decision-making algorithms based on the models developed. The work investigates the heat-carrier’s water-chemical mode at the first circuit of the VVER-1000 reactor. The heat-carrier radiolysis processes’ mathematical modelling is carried out taking into account the change of temperature along the circuit. An algorithm for the steam detection in the heat-carrier at the first circuit of the reactor is proposed. Software modules is developed that implement the algorithms.
