A Slovenian nuclear power plant went back on line Monday, its managers said, after having been shut down last week in an incident that set off a Europe-wide alert.
The managers of the Krsko plant, 120 kilometres (75 miles) east of the capital Ljubljana, said in a statement that it was running again after a faulty valve in its main cooling system was replaced following last Wednesday's leak.
"Maintenance works of this kind are regularly carried out and that's why the repair could be completed quicker than expected," the statement said after the plant went back on line on Monday afternoon.
The site's managers said no radioactive material had leaked in the incident.
But the coolant leak triggered the European Union's radiation alert for the first time since the system was put in place in the aftermath of the Chernobyl disaster 22 years ago
