Lifespan extension of nuclear power plants

EDF Energy completed replacement and modernization of the Data Processing and Control Systems at Dungeness B nuclear power plant with Atos expertise

Paris, 28 June 2016 - When safety and security come first, one cannot afford to make mistakes, adoption and development require the utmost preparation and control. The life span extension of nuclear power plants that is happening worldwide, means the right expertise is needed to ensure modernization and replacement of obsolete systems to remain compliant to the latest regulations. Such a transition needs to be executed whilst guaranteeing productivity in all safety. Atos Worldgrid, an international subsidiary of Atos, is a unique player in smart energy with a strong footprint as a partner to accompany clients worldwide.

Smooth transition at EDF Energy
EDF Energy, the UK's largest producer of low-carbon electricity, wholly owned by EDF Group, commissioned Atos as prime contractor to lead the entire Data Processing and Control Systems (DPS)* replacement and modernization  project. Atos Worldgrid was responsible for the overall design and selection of replacement technologies, the implementation program and delivery at the Dungeness B nuclear power station in the UK. The replacement was carried out without interrupting plant operation and both legacy and replacement systems ran in parallel for ensured continuity prior to the actual switchover.

Training is critical
Under the contract, Atos Worldgrid managed the build, testing and commissioning of the new system.  The system is designed to meet EDF Energy's specifications supporting the operation of a nuclear plant. These specifications include adherence to stringent national and international standards. Atos worked closely with EDF Energy's design staff in achieving the necessary quality. Training for control room operators was critical, and Atos ensured that the new systems were fully integrated with the simulator environment well in advance of transition. This meant that all those affected by the change would be fully familiar with the new systems and interfaces before the switchover.

"Atos demonstrated strong technology capabilities through its extensive experience in the energy sector, together with the proven program management skills necessary to ensure the successful running of such a critical project," said Tony Williams, Group Head DPCS C&I Branch at EDF Energy. "We were particularly impressed by their strong partnership approach, as Atos Worldgrid experts worked side by side with us to achieve very high standards required for regulatory approval."
