Each of the twenty 1,300 MW nuclear units in France are equipped with Alstom control system, installed during the construction of the power plants. Alstom has been servicing it ever since.
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 1,300 MW EDF Nuclear fleet in France.
