A Slovenian nuclear plant in the southestern city of Krsko was fully operational again on Wednesday after being shut down for a month for routine maintenance work.
The plant, east of the capital Ljubljana, had been closed since October 6 for regular inspections.
Insulation was added to the reactor building and 53 of the plant's 121 fuel elements were replaced, the plant's management said in a statement.
Improvements were also made to the plant's equipment and technological systems to increase security.
The Krsko nuclear power plant, which is jointly owned by Slovenia and neighbouring Croatia, was built by American-Japanese company Westinghouse and became operational in 1983.
NEK produces 20 percent of all electricity used in Slovenia and satsfies 15 percent of Croatia's power needs.
Slovenia announced last year that it planned to build a second nuclear reactor at Krsko by 2017.
