* EDF declines to comment on BFM TV report
* France already outlined plans to cut down on nuclear
PARIS, May 22 (Reuters) - French state-controlled utility EDF plans to push back the target of cutting the share of nuclear generation in France's power production by 25 years to 2050, BFM television reported on Monday.
France's 2015 energy transition law outlined the country's ambition to curb its dependence on atomic power by cutting the share of nuclear in its electricity mix to 50 percent from over 75 percent currently, while developing more renewable power.
BFM said that according to an internal EDF plan, the share of nuclear generation in that mix will only be reduced to 50 percent by 2050, instead of 2025 as stipulated in the law.
It said EDF plans to extend the lifespan of some of the 58 nuclear reactors it operates in France by 10 to 20 years, increasing their lifespan of the reactors from the 40-year limit to 50 or 60 years.
BFM said also in the report that EDF plans to build 25 new generation EPR reactors between 2030 and 2050.
A spokeswoman for the company declined to comment.
However, a source familiar with the situation said there is no secret plan but added the company is working with several models for future electricity production and consumption.
Two other sources familiar with the situation denied there was a secret plan, but said that the 2050 deadline is in line with EDF's own thinking, and was a more realistic date to get to that 50 percent target.
Environmental activist Nicolas Hulot, the country's new Ecology Minister, confirmed last week that France would seek to reduce the share of nuclear in its power generation to 50 percent by 2025, and would close its oldest nuclear power plant.
