I never said there wasn't. The cleanup is ongoing and will take a very long time, but it still isn't "destroyed for good". At least the caesium eventually goes away. The Pb, Hg, and As in the 1.1 billion gallons of fly ash slurry that the Tennessee Valley Authority spilled[0] over homes and into the Emory and Clinch rivers doesn't have a half life.

The tsunami also did incredible damage to the economy and agriculture of Japan.
> Can you claim without flinching that this will never ever happen?
Absolutely. Even the idiotic RBMK design can be run safely after being modified to fix the void coefficient. I suggest actually reading my link[1] above, which explain in great detail the problems in the design of that reactor. Even with those problems, it took incredible effort[2] to trigger the steam explosion.

I'm give a lot of respect and thanks to those that had to deal with Chernobyl's immediate aftermath and the 600,000 liquidators that were part of the cleanup afterwords. In particular, the 3828 people that cleaned up the worst section of roof in two minute shifts. Their story - in their own words[3] - is something I will never forget.
