That's bad of course. But after a short time people can live there again. If something like Chernobyl or Fukushima happens the land is lost for decades and has a very huge impact (fallout, radioactive waste, groundwater contamination, etc.).
You may argue that these are just two big incidents but with all the old plants with bad condition (e.g. Beznau, Fessenheim, etc.) in mind I'd say we'll see more bigger incidents in the next years.
In most discussions the time is ignored. Nuclear power plants already produced waste for many generations which is irresponsible.
