From the BBC:
A nuclear power station being built in Somerset is on track for its next major milestone, the firm behind it has said.
The construction of Hinkley Point C began two years ago after the government signed a deal with French firm EDF and its Chinese partner CGN.
It is expected to provide 7% of the UK's electricity needs for 60 years.
The oldest functioning nuclear power plant will be fifty years old next year. Assuming we've learned more than we've forgotten since 1969, a sixty year life span seems perfectly plausible.
