French power group EDF has awarded nuclear reactor maker Areva a contract worth more than $799 million to upgrade the monitoring and control systems of 20 reactors at power plants throughout France, Reuters reports.

The upgrade will guarantee the safety of its 1300 MW power plants.

“The work is an integral part of EDF’s industrial programme for the continuous improvement of its nuclear installations,” the company said in a statement on Friday.

“The aim is to enhance the performance of the monitoring and control systems, which guarantee nuclear safety.”

As the principal contractor, Areva will draw on its extensive expertise and will be working primarily with its partner, Rolls Royce, whose teams are based in Grenoble, to supply the majority of the technology associated with this contract.

According to Reuters the work will begin in 2015 to coincide with the third 10-yearly reactor inspections.
