Well, that's a false dichotomy, because no-one's (at least no-one reasonable and in good faith) is suggesting shifting the grid entirely to nuclear. Instead, a diverse set of generation sources is ideal, including solar, wind, nuclear and hydro.
Well, the point of this thread is that's only true until a sufficient level of availability is required, and then nuclear (and fossil thermal plants) all of a sudden become a viable option again.
