There's also, honestly, the fact that full-size nuclear plants look threatening. They have an imposing size and shape, they dominate the horizon, they look like "if that thing blew up it would be catastrophic" (I know that's not exactly what happens, but still)
So as dumb as it sounds, just making the thing smaller might be enough to soften public opinion
Another reason to move to GenIV reactors, because once you don't need cooling towers. So if you design it right, most people will not even get that it will be a nuclear plant.
Its really the cooling towers that make it clear what it is and those look absurdly big.
