Half of Russia's nuclear generation in 2015 came from units which had been upgraded for long-term operation, Oleg Chernikov of Rosenergoatom told the 11th Public Forum-Dialogue in Moscow. Twenty four of 34 operable reactors have been upgraded, he said, adding 3 GWe of generating capacity - roughly equivalent of three new reactors. The same kind of upgrades are currently being made at five further units, while the remaining five reactors are new. Chernikov said the country's VVER units could potentially justify operation beyond the age of 60, subject to further knowledge and experience.
