Abstract

The necessity of modernizing current control systems for functional units of a nuclear power plant, as well as the development of new control systems with a high degree of reliability and speed, is substantiated. The advantages of using optical sensors and fiber-optic communication lines to solve these problems are noted. Cases for which it is necessary to develop new fiber-optic sensors for monitoring parameters, for example, the flow of coolant or feed water, are considered. In some of them, it is more expedient to use standard designs of fiber-optic sensors to control the operating parameters of various blocks, for example, to control the electric field strength. A device and a control scheme for the parameters of the units and systems of a nuclear power plant using fiber-optic communication lines have been developed. The results of measuring various parameters of a nuclear reactor are presented. They showed that our proposed fiber-optic control and monitoring system for nuclear power plants operates more reliably and efficiently than systems with analogue control and measurement channels. The use of fiber-optic systems allows real-time remote control and high-speed control in terms of issuing commands to devices. This is very important when servicing a nuclear power plant while it is operating in extreme conditions.

Summary

Introduction

Every year for the sustainable development of society requires more and more electric energy [1-14]. When operating nuclear power plants (NPPs) of various capacities, several tasks arise. One of them is the creation of control and monitoring systems that ensure the stable operation of equipment operating in continuous mode at nuclear power plants [25-32]. To provide reliable remote control of various systems and units of the station, for example, when the station is decommissioned, or in the “conservation” mode of a nuclear reactor [6, 9, 23-26]. The greatest difficulties arise in the development of these systems for nuclear power plants of medium and low power. When developing systems for nuclear power plants of medium and low power, difficulties arise due to the peculiarities of their operation - such stations can be located on mobile facilities, where both the space for them and the number of staff are limited [6, 9, 19-22]
