Re: Utterly unreliable nuclear power !
Interesting. It never ceases to amaze me that such complex systems of engineering, management politics and economics such as nuclear reactors (based on militarily-usable PWRs, natch) can even be built at all.
OTOH, if nuclear reactors show this kind of problem in manufacture, expect similar problems to occur in wind power installations. Long series of cracked shafts, broken wings and waterlogged alternators (as well as companies going titsup, nullifying expectations of investment paybacks) are likely to await in the future.
Incidentally, Paluel 2 has been offline since May 2015. Its maintenance period is continuing, following an incident on March 31, 2016, in which a 465-ton steam generator tipped over during removal.
OTOH, I have the impression the new generation of engineers is not up to snuff.
