The Netherlands, March 11, 2021 – AEG Power Solutions, a global provider of power supply systems and solutions for industrial, critical infrastructure and innovative power electronic applications announced its selection to deliver the power back-up for the Local Crisis Centers ( CCL) of 11 nuclear power plants in France. Contract was signed with Valiance, a subsidiary of the Fayat group, focused on nuclear power applications, which has been granted the complete electrical and control systems package of the crisis centers.

Designed to withstand accident levels (earthquake, flood, tornadoes, etc.) of a great magnitude, the CCLs are built to enable the management of a facility independently and safely in any situation. The initiative derives directly from the additional safety assessment which concluded a large audit carried out by The French Nuclear Authority (ASN) and EDF after the Fukushima accident. The utility operator implemented a set of measures aimed at ensuring the sustainability of the French installed base of nuclear power plants by guaranteeing their integrity in any situation. The installation of local crisis centers is one of the important measures of this post-Fukushima era. EDF implemented a first center in Flamanville Nuclear Power Plant as a prototype. The final concept of the other CCL and the schedule of their implementation are a result of this first experience.

The centers are planned to be built in Belleville, Blayais, Bugey, Cattenom, Civaux, Chinon, Cruas, Dampierre, Gravelines, Saint-Laurent and Tricastin. Six others are planned as a second step to cover all existing plants.

Located outside the site, the CCL provides everything required for a comprehensive crisis management with independent telecom resources, a decontamination zone, water and electricity autonomy, air purification and life logistics. It can accommodate the team members of crisis management autonomously for three days.

Continuity of power supply in such situation is not an option. AEG Power Solutions is providing the power supply back-up of the sites with a solution combining Profitec S N1 rectifier, Transokraft N1 inverter and VRLA batteries. Both systems are fully analog and class 1E certified. Beside the obvious requirements for seismic or flood resistance, which both systems are designed to meet, the main challenge was to provide a battery autonomy significantly expanded compared to standards. AEG Power Solutions team engineered a solution so that the charger could handle an increased battery capacity and grow up the autonomous supply up from the 70mn initially specified to the 4 hours finally required.

“We are very proud to contribute to the CCL projects. Our analog systems have proven track records in the field as our technology has been used in plants nuclear power around the world for about 50 years and AEG Power Solutions nuclear team has also a very sound experience in project management , explains Frédéric Perdigal, Area Sales Director”.

The first center to be equipped will be in Tricastin at the very beginning of 2022.
