Abstract:

The need to develop an optical system for remote monitoring of the state of the coolant in the current flow in the first circuit of the nuclear reactor of a nuclear power plant has been substantiated. A method for monitoring the state of the coolant by changing the nature of the evolution of oxygen activity is presented. A fiber-optic system has been developed to study the nature of the change in the evolution of the oxygen activity of the coolant in the current flow.
The results of the study of the evolution of oxygen activity in the current flow of the coolant are presented. The nature of the change in the evolution of oxygen activity in the event of the ingress of foreign particles into the coolant (carbon steel particles from welded joints) is determined.
