Roselectronics, part of Russian State Corporation Rostekh, has developed a new generation of industrial television systems with high radiation resistance. They are designed to control technological processes in the reactor zone, as well as visual monitoring of its condition. This is necessary to maintain the operability of the key element of the nuclear power plant and prevent emergency situations. Experimental samples will be tested until the end of 2024.
The modernised video surveillance system was developed by Roselectronics Research Institute of Television. It is planned to be used to inspect the condition of reactor vessels and internal equipment, monitor the removal and installation of fuel assemblies, as well as monitor technological operations and fuel reloading processes in the reactor and cooling pool.
The complex includes a radiation-resistant chamber capable of operating in air and water environments with instantaneous gamma radiation up to 2 mrad/hour or accumulated gamma radiation up to 200 mrad. The company’s own lens makes it possible to obtain colour and black & white images with a resolution of at least 1000 television lines at ambient temperatures up to 120 degrees Celsius. The camera is controlled using a television system unit with a membrane keyboard. All controllers are “sewn” into the panel, which allows it to be safely used in reactor rooms and other nuclear facilities.
“The Research Institute of Television has unique expertise in the development and production of radiation-resistant video surveillance equipment,” said Institute Director General Alexei Nikitin. “The use of new optics and a minimum number of components inside the camera made it possible to achieve high performance and expand the conditions for using such systems. By the end of the year, we plan to test prototypes to confirm the characteristics laid down in the technical specifications.”
