The general point is true - the fact that nuclear installations operate on a 60 year operational timescale does make them financially very vulnerable to disruptive innovation in energy production (altough electricity prices would have to fall very far indeed before they get turned off on economic grounds. The marginal cost of keeping an extant reactor operating is insanely low.) heck, a superior nuclear reactor design could completely wreck your financial return.

But predicting distributed solar is going to be the killer? In europe? Nuh-hu. Kite gen. Large scale storage. Conventional wind. Solar imports from the sahara? Sure, I can see those pushing prices down. Solar panels on your roof?

Eh. No. Just not happening.
