The European Commission issued a bloc-wide alert after a nuclear power plant in Krsko, Slovenia, began shutting down due to a technical problem with its cooling system. No damage was caused to the environment.
The environment has not been affected, said the European Commission
The plant's primary cooling system lost coolant, the Commission said in a statement on Wednesday, June 4.
"The plant has been stopped preventively for some hours to allow the personnel to determine the cause of the failure and fix it," it said, adding that there had been no discharge to the environment.
The European Community Urgent Radiological Information Exchange (ECURIE) immediately informed all 27 EU members of the incident. ECURIE requires early notification of all nuclear emergencies.
Located in Krsko about 100 kilometers (60 miles) east of the capital Ljubljana, the nuclear power plant was constructed in the late 1980s and is co-owned by Slovenia and neighboring Croatia.
