Don't build it near millions of people. See this map of the UK[2]; London, Birmingham, Liverpool, Sheffield are where the most people are, and where the nuclear power plants aren't.

Dramatic, sure, but nuclear power kills far, far, far fewer people than buckets of water or BIC lighters.
For Chernobyl the overall death toll is estimated between 50 and 4000. Nobody knows and nobody knows how to even count. How do you count the disabled and sick babies born after it?
For Fukushima 1600 fatalities were reported during evacution. I am not an expert, but I guess it's difficult to attribute because the whole area was devastated already by the tsunami.
There will be lucky outcomes also in the future. But if you have hundreds of thousands or millions of people around, some day we'll be out of luck.
If a Jumbo crashes you expect around 400 death. If 2 crash into each other it's twice as many (search for Tenerife if you are too young to remember). If you build 2 skyscrapers for 16,000 employees you risk 16,000 deaths if the worst happens ("Less" than 3000 died, so the cold facts aren't that bad after all.) If you build build a nuclear power station with millions of people around, you risk many more deaths. Not everyone of them immediately, but cancers caused by radiation will continue for decades. Building such things is engineer hubris and some day something worse than what we have seen so far will happen.
