At 11 am Mar 16 JST (10:00:00 p.m. Tuesday March 15 ET) JAIF issued a status update on the Fukushima Daiichi reactors.
The difference I noticed from the earlier JAIF report 3 hours ago is that the fuel integrity of the fuel rods in Unit 4 spent fuel pool (SFP) is shown as "SFP Level Low damage to fuel rods suspected". That might explain the hydrogen explosion reported at Unit 4.
