You can't really measure safety in terms of deaths. Chernobyl only officially killed a handful of people, yet rendered a huge chunk of land uninhabitable. When nuclear goes wrong, it goes really wrong.

And yes, you can argue that that Chernobyl was an old reactor design, Fukushima was complacency, but the reality is that technology always goes wrong. I'd rather have technology that catches fire (wind turbines) than technology that gives people cancer and forces entire cities to migrate (reactors) when it goes wrong.
