Look, just because it's a PWR, doesn't mean it's a bad design by default.

Fukushima was a Gen II reactor. These new reactors are Westinghouse AP1000's and they're classified as Gen III+. By comparison, Fukushima's reactors are archaic in design.

Gen III+ reactors are smaller, and are greatly simplified designs, and most importantly, have passive cooling features. Passive cooling is what Fukushima didn't have. If the external power gets cut to these new reactors for an extended period of time, AND the backup generators get knocked out too, they can leverage these passive features to cool the reactor and prevent a Fukushima-style event.
