Remote Monitoring of Piping Systems in Power Plant

Piping in nuclear power plants is exposed to severe environmental conditions. For safety rating it is mandatory to inspect the piping systems thoroughly. However, inspection of piping systems in nuclear power plants is not easy in practice because of their length and the radioactive environment.

Korea Hydro & Nuclear Power selected m+p international’s Coda data acquisition system for remote piping monitoring in real-time at their Wolsong Power Plant in Gyeongju, South Korea. The Coda system measures the static and dynamic data of all steel pipes throughout the plant: in the turbine room, in the reactor, etc. The networked monitoring system consists of the Coda acquisition software installed on a standard PC and DAQ instruments which are located directly at the pipes.

Coda supports more than 250 channels to measure the thermal expansion, temperature, pressure, vibration and weight of the pipes at Wolsong Power Plant. These measurements are taken by using thermocouples, LVDT (Linear Variable Differential Transformer) sensors, pressure transducers and strain gauge load cells.
