The Chernobyl exclusion zone is relatively safe... to short, limited tours. There are radioactive and toxic particulates all over the place. Things like Cesium-137, which is both radioactive and toxic. Artifacts irradiated in the initial meltodwn and radioactive release (eg vehicles, buildings) remain dangerous to this day, like there are machine graveyards that are absolutely forbidden to entry for safety reasons.

Yes, about a trillion dollars. That's the point.

As for technology, I believe the removal of fuel rods and irradiating sand bags has only begun (with robots) in the last year. I don't believe they've fully mapped out what needs to be removed. It's not just the fuel but also the structure, such as the concrete pedestal the reactor was on (and melted through to).

Otherwise, you kinda make my point: hand waving away serious and expensive disasters with fervor bordering on the religious to essentially dismiss me as some kind of heretic.
