Belgium’s Doel nuclear reactor went offline on Saturday, after it was restarted just three days ago, the plant’s spokesperson said. Meanwhile, Germany has stepped up criticism on operational safety of its neighbor’s aging nuclear facilities. Doel 1 nuclear reactor, located in northern Belgium, was taken offline automatically, RTL broadcaster quoted the communications manager Els De Clercq as saying. At this point there is no safety risk, AFP reported, citing power utility company Electrabel, which operates the plant.
