This article discusses the problem of ensuring the control of the state and strength of the device for handling radioactive materials at nuclear power facilities and proposes the development of a remote ultrasonic control system for continuous-periodic monitoring of the state of critical structural elements of the service traverse operating in a radiation hazardous environment. The basic principles of processing the results of ultrasonic flaw detection and obtaining characteristics are given.

Regular inspection of water supply and sanitation networks helps to reduce accidents that occur in engineering communications. To check the regulatory and technical documentation is recommended to use tele-inspection systems that allow you to get the most accurate information about the technical condition of pipelines in a short time. The article deals with the review and analysis of modern technical systems for tele-inspection and trenchless repair of pipelines. The article considers the requirements of regulatory and technical documentation for such systems. We consider the classification of tele-inspection systems for diagnostics and repair of pipelines by functional characteristics. A review of the current market of domestic and foreign-made technical equipment has shown that all devices for TV inspection of pipeline networks can be classified as follows: push-through TV inspection systems, robot-controlled TV inspection systems and TV inspection systems for trenchless repair. A review of the current market of domestic and foreign-made technical equipment has shown that all devices for tele-inspection of pipeline networks can be classified as follows: push-through tele-inspection systems, tele-inspection systems with remotely controlled robots, and tele-inspection systems for trenchless repair
