“Note though, that this briefing says the reactor was destroyed before it was loaded with uranium fuel, on Monday but the chief of the IAEA confirmed that they had found traces of Uranium at the site”

The Israelis obviously had a guy on-site providing them with intelligence. The best time to destroy a nuclear reactor would be when the unactivated fuel rods were on site but not yet loaded into the reactor. The unloaded fuel rods would not have been activated thus containing almost no fission products. Waiting to destroy the reactor until after its fuel rods were loaded would have been ill advised. Doing so could easily have resulted in a Chernobyl situation with a horrific fall-out plume spreading out over hundreds of kilometers (particularly if the reactor used a graphite moderator as seems to have been the case). However destroying the reactor with the fuel nearby but unloaded effectively killed two birds with one stone.

This action by Israel was brilliantly done and represents another feather in their cap (right next to the one they earned for destroying Saddam’s Osirak Reactor). Too bad they can’t seem to do anything about the Iranians.
