GAUGING INFORMATION SYSTEMS, MEANS OF TECHNOLOGICAL DIAGNOSTICS AND INTELLIGENT GAUGES IN NUCLEAR POWER ENGINEERING AND INDUSTRY.Current state and perspective views
Measuring information systems, process diagnostic facilities and smart sensors (automated nondestructive testing systems ANDTS) perform measuring, monitoring and control functions. They ensure safety use of NPP, nuclear power and industrial operations, and are extensively used in the defense industry, scientific research, medical care, agriculture and ecology.ANDTS are used for: ??NDT and diagnostics of units and devices ??material/facility component makeup control ??process automation. Use is made of hardware methods of measured parameter recording, automated control data decoding, documenting and long-term storage, including those for especially hazardous production control.ANDTS enable real-time bundled software-assisted detection and identification of a bomb or a pre-emergency facility status. Portable analyzers help identify especially hazardous materials and determine the content of heavy and toxic elements in aqueous media and atmosphere. In the process of establishment the nuclear industry has developed a new sustainable line of business nuclear instrumentation and measuring information technologies. They went through a number of stages and used a wide variety of the current achievements in instrument circuitry and design, development of detectors, recording hardware and methods and ramified control systems. Advanced measuring information systems are based on sensors that provide incoming initial information. Such sensors, too, have been through several development stages. The initial stage involves use of gages primarily to obtain data on physical quantity values that did not represent measurement information until processed by man. Sensor evolution led to creation of information collecting tools equipped with their own computers and based on state-of-the-art technologies (including Internet technologies) for data processing and transfer to top-level systems. Such sensors which in some cases handle process control tasks alongside information tasks are known as smart sensors. The specific character of the nuclear industry demanded a wide use of nondestructive testing and process diagnostics (NDT and PD) and some special features of sensors: provision of rational isolation from operating personnel, high resistance to destabilizing factors, and consistency with the process control system. All this required application of a system approach, high degree of automation, computer facilities and robotics, highwaymodule design method etc. in designing the sensors. A choice of an NDT method and instrument for the purposes of fault detection and technical diagnostics depends on the parameters of a tested object and inspection conditions.
