NRC's Operation Center Fukushima Transcript Audio Clips March 16 2011
Paraphrasing: With Mark 1, with station blackout you are going to lose containment.
Units 1 and 2 are "boiling down."
No walls on unit 4. "Lost geometry" on spent fuel pool #4. The "side of the reactor building" (4) are gone. No water in there at all.
Paraphrasing one person's articulation of worst case scenario: 3 reactors in meltdown with primary containment lost and up to 6 spent fuel pools in degraded condition possibly with spent fuel pool fires.
Another speaker (paraphrasing): It has progressed to 2 multiple reactors and multiple spent fuel pools and maybe 4 reactors and 4 spent fuel pools.
"We haven't seen any mitigation of any events."
"you got to assume it is going to go to the final event..."
