Romania operator expects little change to 2013 nuclear output

It estimates the plant's two units will produce 11,471 gigawatt hours (GWh) of electricity in 2013 versus 11,466 GWh last year.

Output fell by more than 2 percent in 2012, the company said in an email.

Nuclearelectrica has two 706 megawatt reactors at Cernavoda, accounting for roughly one fifth of the country's power production. It aims to add two more units by 2020.
