Oh, I should have added: this claim isn't really true either. The WHO estimates that a million people die each year due to air pollution from coal plants. This is many orders of magnitude higher than the annual average deaths related to nuclear energy.

The difference is, there isn't a worldwide push to ban coal because of this; instead, there's a push to scrub the plant emissions to remove the pollution. So again, nuclear is treated much more strictly than other power sources, relative to its actual risk.
