Slovenia is closing down its only nuclear plant temporarily following a leak in the cooling system. A spokesperson for the Krsko site said engineers were busy analysing the problem, but there is no danger to the population or environment.
The plant, east of the capital Ljubljana, was reopened last November after being shut down for a month for maintenance work.
In Brussels, the EU issued its European Community Urgent Radiological Information Exchange system, which alerts all 27 member states to any potential nuclear emergency.
The plant, jointly owned by Slovenia and Croatia, produces 20 percent of all electricity used in the country and provides 15 percent of Croatia’s power needs.
