This must be peak nuclear cultism? Trying to downplay that any evacuation was needed to happen when Fukushima was out of control actively melting down and going through hydrogen explosions.

You are also missing that the evacuation was expanded in stages:

- Accident day: Loss of cooling, 3 km evacuation.

- 1 day after: 10 km. Followed by extended to 20 km when unit 1 exploded. Followed by unit 3 and 4 exploding as well.

What did Japan's nuclear regulators do after Fukushima? They expanded the emergency planning zone from roughly 8 - 10 km to 30 km.
