I have a fascinating report from a well known investment bank that I can't post due to copyright issues, but I can quickly summarize.
1. The phrase "spent" fuel rods is potentially misleading, because the term spent doesn't mean inert/inactive. It means their usefulness is spent because they have accumulated additional neutrons from the fissioning process adn thus become MORE unpredictable and MORE radioactive. Spent rods have more radioactive particles than in the operating reactors.
2. A Brookhaven National Laboratory study using OLDER spent fuel than at Fukushima estimated that all water would boil away after 40 hours, a much shorter time than what has otherwise been posted on this thread.
3. The Fukushima spent fuel pools are near the top of the plant, which makes them harder to deal with, and a generally more dangerous situation. It's also not entirely clear what happens when you pour water on spent fuel rods if the zirconium casing has been compromised.
4. According to the newsletter, and something I haven't seen elsewhere, it's possible that all the power problems stem from having the fuel storage tanks for the backup generators sitting OUT IN THE OPEN ON THE FRICKING BEACH, with aerial photos suggesting the tsunami completely took them out to sea. If they had just had the fuel protected (underground or within sturdy structures), maybe none of this would be happening, comparing the situation at Daiichi to Daini, only 10 miles away, where the situation is stable (and where the fuel for the backup generators was not compromised).
