My point isn't that 'leftists' (a decreasingly useful categorisation in any case) aren't anti-nuclear. It's that this anti-nuclear stance has been causally impotent in most of the nations that haven't chosen to build much nuclear capacity. Australia is a great case in point - even its 'leftist' party is very right-wing (pro-coal, pro-asylum-seeker torture, etc), yet the population, right and left alike, simply will not countenance nuclear power.
There's a great tendency for political pundits to confuse the positions and divisions of lobbyists, politicians and insiders with those of the population at large. Anyone attributing lack of nuclear capacity to 'leftists' is doing just that.
Also, it does fall squarely on one side of the industrialist side of the industrialist-populist divide of the right.
