Hendricks`s request stems from a report from Germany`s independent Reactor Safety Commission (RSK), which concluded that security reserves at the two reactors were sufficient for normal operation, but problems could arise in the event of a fault.
"Therefore, I think it is right to take the sites off the grid, at least until further investigations are concluded," said Hendricks, speaking during a stop on an official visit to China.
Tihange 2 and Doel 3, part of larger nuclear plants with three and four reactors, respectively, were taken offline in 2012 after it was found that there were defects in the reactor pressure vessels.
Belgian nuclear officials concluded toward the end of 2015 that the reactors were safe enough to be put back online.
Germany reacted nervously to the reactors being put back online, and a working group of officials from both countries met earlier this month to discuss the issue.
