I read that the total amount of fuel at Fukushima is about 2000 tons and that the six reactors contained 100 tons.
It's complicated to compare the contamination potential of a bomb with that of the Fukushima incident, but there's certainly a lot of "stuff" at Fukushima. What an incredible mess.
The two of you are aware that the fuel rods there contain only 3% enriched uranium when installed, correct? I’ve seen photos of people sitting on fuel rods before delivery to a nuclear facility, and they can do that because the radioactivity is so low. Not true after a runthrough.
The resulting plutonium after fissioning isn’t all that great an amount but it is still ‘hot’. After a few years in a spent fuel pool it can be stored in the open air.
