       | I don't mean to be negative about nuclear power, I just feel that
       | in recent years in online discussions nuclear power has become
       | this mythological source of power. We're discussing all the
       | challenges and issue with renewables in such detail. But the
       | discussion of nuclear is so surface level, focusing mainly on
       | public fear and regulations.

         | 
         | This isn't new. When nuclear was more cost effective than
         | solar/wind they turned the "environmental" lobby against
         | nuclear.
         | 
         | Now that wind/solar is more cost effective they're turning the
         | nuclear crowd against solar/wind.

         | 
         | Also its only specific to some reactors that are on the rivers,
         | the ones that are next to the sea doesn't have this limitation.
         | 
         | Meanwhile heat on solar panels can reduce their efficiency by
         | several percents per degC added. And heat also affect wind
         | turbine (less wind) by several percents as well when the Tdeg
         | is going up.
         | 
         | Annnddd there's exactly the same limitations for all the other
         | plants (coal and gas) that are built next to a river.
         | 
         | So yes the plants will have to limit their power more and more
         | in the future due to global warming and water limitation (if
         | they are on rivers), but it was already anticipated and doesn't
         | have that big of a impact for now.
