LPMS(Loose Part Monitoring System)

Overall Confugiration

LPMS was installed at 8 site of Korea Hydro & Nuclear Power Co.,Ltd

LPMS can prevent accidents such as damage of reactor coolant system and structure, rod operation hindrance, and steam generator tube leakage; hence, an important system for higher power plant safety insurance.

This system judges the risk and confirms the existence of these loose parts by assessing risk of RCS's internal structure damage and breakdown of power plant for economical and safe operation of the power plant.

The metal loose parts inserted from outside of nuclear power RCS(DP) and generated internally within the system travels the inside of structure along with high-speed coolant could cause a critical damage to the inner structure of RCS.

LPMS is a monitoring device that detects the shock wave generated from the collision of loose parts and pressure limitation internal structure by mounting accelerometer(shock wave sensitive sensor), where loose parts gather naturally.
