"MSTL" monitoring system for tension level of containment tendons is designed to provide measurements and monitoring the stress level of the tendons tension level in the containment prestressing system of VVER-1200 type reactor plants both during its commissioning and later throughout the entire service life of NPP.
The purpose of creating MSTL is to improve the reliability of containment prestressing system operation at NPP power units and, as a result, to enhance the level of nuclear and radiation safety of power units.
The principle of operation is based on measuring physical quantities (by primary transducers), converting them into electrical signals, converting the signals into digital codes and transmitting them to the workstation that processes measurement results, accumulates, stores and outputs information for further use.
The sensor-string signal converter transforms analog signal into digital code. The received data is sent to programmable server and transmitted to the workstation. The software processes received information and displays the results of force (tension) measurement and control on the monitor.
