Around 11:07 AM on September 22nd, while working on removing debris from atop the crippled reactor building, a heavy thousand pound steel frame was knocked into Reactor 3’s spent fuel pool.

The steel frame was located on the south-eastern pool side, and it was hit by the tip of a crane during debris removal work.

TEPCO workers used an underwater camera early Monday morning investigate and check if there is any fuel damage.
