"Global Nuclear Decommissioning Cost Seen Underestimated, May Spiral"

"German utility E.ON's breakup has led to worries that funds set aside for decommissioning reactors will not suffice, but globally the cost of unwinding nuclear is uncertain as estimates range widely.

As ageing first-generation reactors close, the true cost of decommissioning will be crucial for the future of the nuclear industry, already ailing following the 2011 Fukushima disaster and competition from cheap shale gas, falling oil prices and a flood of renewable energy from wind and solar.

The International Energy Agency (IEA) said late last year that almost 200 of the 434 reactors in operation around the globe would be retired by 2040, and estimated the cost of decommissioning them at more than $100 billion."
