We have no reliably accurate data on deaths and illnesses caused by the nuclear power industry. From the mining to the waste disposal, and the plant operation - they all have very significant mishaps putting cancer-causing radioactive materials into the environment where it circulates for generations. There is no way you can honestly make such a statement because we have no way of knowing how many of the people dead from e.g. thyroid cancer are the result of nuclear energy related activities.

I strongly encourage you to watch [1]. Nuclear is such a disaster it's mind-boggling that anyone would still argue in favor of it today over the alternatives.
If motor vehicles were held to the safety standards of nuclear power, we would all be riding bicycles.
