Alstom to retrofit control systems at EDF's nuclear power plants

Alstom Thermal Power has been awarded a contract worth over €50 million ($62.8 million) to retrofit the Controbloc N20 units for the 20 nuclear power plants owned by Electricité de France (EDF). All of the nuclear units totaling 1300 MW are equipped with Alstom control systems that were installed during the construction of the plants.

Controbloc N20 is a control system for power plant operators, which enables them to improve the control of their plant with various sensors throughout the plant monitoring components such as valves, actuators of pumps, engines and electrical units. Alstom will modernize the current system, adding new technology, based on its latest ALSPA Series 6 control system, to the existing Controbloc N20. Deployment for the first retrofitted unit is scheduled for spring 2015.

The retrofits are part of the standard lifetime visits and life extensions plans for the nuclear fleet in France.
