The Belgian nuclear watchdog organization AFCN said Thursday that a reactor at one of the country's two nuclear power plants was shut down on Thursday night after a hydrogen leak began.
"The Doel 2 reactor was manually shut down on the night of July 14 to July 15 … after employees at Engie Electrabel noticed a rapid increase in generator hydrogen consumption, indicating a leak," the statement said.
One of Doel's two reactors was preemptively shut down to mitigate potential risks, the regulator said. The cause of the leak is unknown and the reactor will not be restarted until it is found.
The Belgian arm of the French energy giant Engie said it has also stepped up surveillance at the second nuclear power plant, Begium, at Tihang on the Meuse River, after it overflowed its banks.
"The risk of flooding around the Tihange nuclear power plant remains under control and there is no immediate danger to the nuclear power plant. Operator Engie Electrabel has preempted vigilance," AFCN tweeted.
Record rainfall has brought down several houses in Belgium and caused catastrophic flooding in neighboring Germany, resulting in the death of at least 60 people in Germany and more than 11 in Belgium, with 1,300 missing.
