We put the nuclear "waste" in breeder reactors. Problem solved. What's left decays fairly quickly and needs a couple of warehouses every fifty years.

No form of energy generation causes zero deaths. Chernobyl was a reckless expirement that went wrong. Fukushima is in no way comparable to Chernobyl regarding the amount of radiation released. We could increase security by stopping to demonize nuclear power and make it possible to build modern plants instead of running decades old designs with known flaws.
