There are limits to economically extending the life of an aging instrumentation and control (I&C) system. For example, spare parts management or retro-engineering of obsolete electronic printed circuit boards create both effort and risks. Incorporating the latest safety requirements can also be quite challenging and costly with an aging system. In addition, any new system components must be compatible to the old ones.


Optimized I&C upgrade package designed to secure safety 
The most economical approach for long-term operation (LTO) is often to refurbish or to replace the upper layers of the I&C chain. Depending on the complexity of the functional evolutions the utility needs to achieve, it can opt for a complete digital system, an analog system or an optimized combination of both. Based on its nuclear power plant (NPP) manufacturer experience in safety and as a developer and integrator of I&C systems, AREVA NP can provide full I&C system packages that include the most suitable solution in accordance with customer and safety authorities latest requirements. The offer includes supply, integration, installation and commissioning of new I&C systems.
