“We have launched an in-house investigation. While shutdowns are not unusual, they have already reached the total number estimated for this year,” Lulache told a conference organized by Ziarul Financiar.

Nucleareletrica is majority owned by the state, through the Energy Department. The company operates two 700-megawatt reactors in Cernavoda, covering around 20% of Romania’s energy consumption.

The two reactors shut down unexpectedly several times in the past few months. The latest shutdown occurred in late October, when nuke 1 stopped due to a malfunction at the control system.
