Primary 1 Fukushima: the possibility of containment of the hole and the No. 2 No. 1, Mainichi, May 25, 2011:
The first nuclear power plant 24, TEPCO announced Hukushima few reports in which there was a meltdown in the No., 1 No. 7 cm in diameter, equivalent to a hole in the containment vessel outside the reactor pressure vessel, two The first rocket was shown it is possible that more than one hole 10 inches in diameter, equivalent to the containment. [...]
In Unit 2 from the measured pressure data, equivalent to more than one hole in the containment of 10 cm, has floated the possibility of a considerable hole in the No. 1 7 cm. [...]
Multiple 10-Centimeter Holes in Reactor 2 Containment Vessel at #Fukushima I Nuke Plant, EX-SKF, May 24, 2011:
[...] From Mainichi Shinbun Japanese (2:30AM JST 5/25/2011)
[...] In the report that TEPCO disclosed on May 24 regarding the core meltdown in the Reactors 2 and 3, the possibility of holes in the Containment Vessels of the Reactors 1 and 2 is mentioned for the first time. The Reactor 1 Containment Vessel may have a hole 7-centimeter in diameter, and the Reactor 2 Containment vessel may have multiple holes 10-centimeter in diameter.
According to the Mainichi article, TEPCO came to the conclusion of multiple 10-centimeter holes in the Reactor 2 Containment Vessel and one 7-centimeter hole in the Reactor 1 Containment Vessel from the analysis of the pressure data.
