Safety of industrial processes and systems

System analysis and process engineering nuclear

The obligatory high safety level in nuclear plants requires the reliable functioning of various processes, systems, and components. Their necessary interplay and effectiveness must be ensured during all stages of the life cycle of the plant. This implies that their states and properties as well as the suitability of the operational procedures need to be monitored continuously.

In this area, TÜV NORD Nuclear provides services which are based on a longstanding experience as a technical service provider.
