I think I never, ever heard or read anyone saying this, and I think I follow/participate in the debates, before it was cool and everywhere.
Renewable people rather sound like this:
"Employing a variety of power generation methods will give you the most stable power grid."
Where of course quite many "green" people don't want nuclear at all in the mix. Rather more of long distance energy transport (HVDC). And otherwise any option that works and does not pollute, or pollutes less.
(And personally I am not antinuclear as long as the alternative are fossil fuels, so they should be used as a transition technology and long term rather reserved for other application, like powering things in space and remote important sites)
