The redundancies, which include temporary contracts and follow 1,500 cuts announced in 2011, will be discussed with trade unions, a spokeswoman for Areva said.
Areva Germany employs 5,100 people. Globally, the firm has 45,000 staff.
French daily Les Echos yesterday quoted union sources as saying Areva planned to cut 1,000 jobs in Germany between 2016 and 2017.
Wolfgang Niclas, representative for the German IG Metall trade union, said that there will be more negotiations in April.
He added that feared that some sites may close, particularly that at Offenbach in western Germany.
This month, Areva posted a record €4.8bn (£3.4bn) 2014 loss and announced a restructuring plan.
It said it would make savings of €1bn over the next few years and announce a finance plan by the end of this month.
