We've seen a few recent instances of reporters incorrectly stating the fuel in the pools melted. That's incorrect, as the AP reported earlier this year. However, the misconception persists. USA Today included the following in a story published earlier today:
UPDATE: USA Today has informed us that they'll run a clarification that the fuel rods didn't burn. The correction should be appended to the online version of the story and run on page 2A or 3A in the newspaper.
Spent nuclear fuel pools that burned during the crisis are now under control.The spent nuclear fuel assemblies at Fukushima never burned or melted, and in fact, were always underwater. Here's a more accurate description of the accident from the consultants at Advanced Nuclear Energy Systems. You can find this description on page 9 of the report:
Disablement of spent fuel pool cooling and the possibility of earthquake-induced damage to the pools were the cause of great concern, which spurred one-week-long unconventional cooling efforts with helicopters and water cannons. While it was later established that the fuel assemblies in the pools remained underwater throughout the accident, the Fukushima experience does underscore the importance of reliable long-term cooling and protection of the spent fuel pools at nuclear plants.We're sending a note to USA Today asking for a correction. Stand by for updates.

Comments
During early days, some folks though these fuel fragments laying around on site in between the units were from the fuel pools.
It wasn't until NRC's Gary Hollihan identified in one of those NRC Task Force public meetings that the iodine-131 signature on some of the fragments could only have come from a core ejection.
To get that kind of trajectory, it would seem that one of the reactor pressure vessel heads would have had to be dislodged by the explosion.
