Rather than pumping all the pollution and waste products of a coal-powered
plant into the atmosphere and rivers, imagine if you could just pack it all
up at the end of each year into a few cubic meters and store it somewhere.
Yet I'm sure some people would still argue the first option over the second.

I believe we'll need nuclear fusion power systems for quite a while.
And I think there's been considerable advance in our ability to make
them safe and much, much more efficient in their power output per unit
of radioactive fuel used.
Recent dual source reactors combine traditional nuclear reactors, run
sub-critical, with a second source, generally a linear accelerator
beam. This considerably increases safety. These critters also use a
stunt of using spent nuclear "waste" as a jacket for the fission
chamber, increasing neutron production.
This is just one of many improvements in fission plant design, many of
which do indeed use prior "waste" materials in innovative ways.
I've read that coal plants actually produce more radioactive
byproducts than nuclear plants do. Yet we hear little concern about
their radioactivity, only their pollution.
Politics also play a part. Breeder reactors are considered dangerous
due to producing waste that can be used in bombs. So we decide to be
less efficient with more traditional systems in order to be "safer".
I'd sure like better science and less emotion in the matter. If I
were told I had to have a power plant next door, I'd prefer a nuke.
