The integrity of electrical equipment and instrumentation and control (I&C) is vital for the safe and efficient long-term operation (LTO) of nuclear power plants (NPPs). Proactive approaches need to be adopted in order to deal with safety and performance concerns.

COMSY-ELEC (Condition-oriented Aging and Plant Life Management System) estimates the remaining life of active electrical equipment and I&C. 
The predictive tool is an efficient solution for aging management of electrical equipment and instrumentaion and control system (I&C). COMSY-ELEC supports surveillance programs compatible to the requirements of international and national rules. An analytical function compares equipment qualification parameters with the environmental parameter history in order to determine the remaining "qualified life".
