And therein lies the problem. The smarter of the environmental
whack jobs know that full well, and their intent is to kill of
nearly all (or all) of humanity so that it isn't needed. Some of
the smartest ones know better than to say that out loud.

There are _still_ five million people living in contaminated areas
around Chernobyl. Over a hundred thousand were evacuated right
away, and twice that over the next few years. Three quarters of a
*million* people took two years to put out the fire. 63,000 square
miles were contaminated.
And you're right: It *was* small scale - for a nuclear meltdown.
And you still haven't explained how to deal with the waste for
50,000 years.

And for the other 99.99% of humanity? Or would you rather they just
quietly die in the dark?

Precisely the point. There is _no_ solution they will not decry,
other than the extinction of humanity - but everybody else has to
go first.

That is not true. What was dug out of the ground was Uranium,
mostly U238, which is about as radioactive as you or me. That was
enriched, to concentrate the U235 to a high enough concentration to
be fissile (which is it *not* in nature, with the exception of one
deposit in Africa). That means a chain reaction, controllable, but
chain reaction nonetheless. And that means that what you end up
with is not what you started with, and some of it is a *lot* more
radioactive. Hell, spent fuel rods are so hot - temperature wise -
that they have to kept underwater for at least five years before
you can even contemplate what to do with the high level stuff.
According to the Nuclear Regulatory Commission[1], "High-level
wastes are hazardous because they produce fatal radiation doses
during short periods of direct exposure. For example, 10 years
after removal from a reactor, the surface dose rate for a typical
spent fuel assembly exceeds 10,000 rem/hour – far greater than the
fatal whole-body dose for humans of about 500 rem received all at
once."
The actual time it takes for waste to get back to the eqivalent of
the ore it was mined as is between 1,000 and 10,000 years,
depending on how enriched it was. Do you have a plan for storing it
for 10,000 years? Does anybody? And while we're on the subject,
what's the plan for 600 years?
Not to mention the chemical dangers of heavy metal toxins if they
should happen to get into ground water.
Now go take a look at the government's hanlding of such things so
far. Start with Hanford, with 53 million gallons of _high level_
radtioactive waste, 25 million cubic feet of solid radioactive
waste, and 200 square miles of contaminated ground water. The
cleanup has been going on since 1988 - that's nearly 30 years - and
most of that effort has involved pumping the liquid waste from
leaking single walled tanks to double walled tanks - that also
leak, because they were built by the lowest bidder. There really
isn't a plausible estimated cost for an actual cleanup (and nowhere
to store the stuff more long term anyway), but the best estimates
are in the hundreds of billions - for what's known to be needed.
