Finnish electricity company TVO said on Monday that an EPR nuclear reactor being built by Areva and Siemens may not be ready until 2016, contradicting Areva's claims that it would be completed in 2014. "Based on the recent progress reports received from the plant supplier ... TVO is preparing for the possibility that the start of the regular electricity production of Olkiluoto 3 nuclear power plant unit may be postponed until the year 2016," the company said in a statement.
