(……) Modern automated technology process control systems and the chances of attacks on them are examined in this article. It studies worm virus, Stuxnet, and its detection at the Bushehr Nuclear Power Plant. It also analyzes ways of carrying out attacks on critically important objects, and provides analytical tools for the security of technological process systems. The ways for discovering nodes compromised by the Stuxnet virus are proposed. The article considers technological network of typical topology and its typical vulnerabilities; it analyzes the Modbus protocol, the routing system, and passwords on Cisco routers.

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.
