Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
The Major Plant Parameters Table of the Status Report indicated that 1.5m to 2.25m of rods are exposed in each of reactors 1-3 and that the containment vessel of reactors 2 and 3 are at or near atmospheric pressure. This would be consistent with loss of containment vessel pressure. Unit 1 still has about 5 atmospheres of pressure while the readings for units 2 and 3 are confusing, as three of four readings show fractional atmospheric pressures, (with 100kPA being ~ 1 atmosphere.) Only reactor pressure vessel 1 has significant pressure above atmospheric or a reactor temperature close to design limit.

The supression pool in the torus appears to be intact on units 1 and 3 but there is no data on unit 2 where there were earlier reports of an explosion in the supression pool. The 46C reading for the temperature of the spent fuel pool in Unit 2 is consistent with other, earlier readings which are likely IR readings taken from helicopters or UAVs. The report only shows "indicator failure" for Units 1 & 3.
