The units 5&6 of Bulgaria´s NPP Kozloduy, the only reactors still operating in Kozloduy, are currently licensed to 2017 and 2019 (30 years lifetime).
There are plans to extend the operating lifetimes of units 5&6 by 20 to a total of 50 years:
The potential lifetime extension up to 20 years will be examined by a consortium between Russia's Rosenergoatom and France's EDF under a contract signed in April 2012. The results of the study will show whether and for how long the units' operating lives could be extended.
Originally six reactors were built at the Kozloduy plant. Under commitments made by Bulgaria as part of its accession to the European Union units 1 and 2 were shut down in 2002 and units 3 and 4 were shut down in 2006 (all VVER-440 reactor models).
Question of the referendum: “Should Bulgaria develop nuclear energy through the construction of a new nuclear power plant?”
The results of the referendum on January 27 are hard to interpret: 61% said
“yes” and 38% “no”. Solely about 1,500,000 went to vote (20.2% of the last
parliamentary elections’ turnout), which is way below the required 4,350,000
to make the vote valid.
One month later, on February 27, the Parliament took a final decision for the end
of the "Belene" project. Since most of the votes at the referendum were positive,
it was decided to extend the life of reactors 5 and 6 and initiate the construction
of a new reactor at the Kozloduy NPP.
