Belgian police sent most of the staff home from the Tihange and Doel nuclear power plants after three bombs exploded in Brussels.
The plants are located just over an hour southeast of Brussels, where bombs blew up at the international airport and metro station, killing 34 and injuring 170. Only personnel who are strictly necessary for the plants' operation remain on site.
Plant operator Electrabel amped up security at both the Tihange and Doel plants following the attacks when authorities raised the security alert to level 4 in the country. In addition to normal security measures, security is also performing systemic checks of vehicles. There is no word on whether any threats were made against the plants.
