Arnie Gundersen of Fairewinds Associates says:
Reactor 1's fuel melted and probably dropped to the Containment Vessel;
Reactor 2 is leaking like a sieve;
Reactor 3 may have another hydrogen explosion;
The plant has sunk about a foot, and the concrete foundation may have cracked.
So what was the "step forward"? That TEPCO was able to enter the Reactor 1 reactor building to install equipments to measure the true water levels.
He also refers to the ramification on the US nuclear regulations now that it has been proven possible for a Containment Vessel to get damaged. The Containment Vessels for the Reactors 1, 2 and 3 at Fukushima are all officially acknowledged to have been damaged.
Toward the end, he mentions a high school in the contaminated area 50-60 kilometers from the plant. He says it is unconscionable to keep the school open.
