Well today,
we are sold the EPR 2 as better because bigger and cheaper.
Cheaper because strangely French engineers found that by standardizing the SS tubes sizes and their supports, it costs less !?
Better because bigger, very basic male reasoning.. Don't believe that nuclear engineers today are the ultimate.. Enrico Fermi cannot be cloned ad infinitum.
These EPR 2 have vibration problems in the reactor vessel in relation to poorly controlled incoming and outgoing cooling flows. Experts are very concerned about this impact on the tubes resistance containing the fuel, which could degenerate into a reaction that over runs. In the daily newspapers, everything is fine. The EPRs are our national pride
EPR is running, though. Vogtle is a gigantic doorstop for now.
