Title: TEPCO Soundness Report On Unit 4 Admits Larger Failures
Date: Sept 5, 2012
TEPCO released two reports in Japanese last week on order of NISA to explain the soundness of unit 4.
The new reports make some key admissions. The west and south walls are degrading and also may have been worse than TEPCO had previously admitted. Floor damage is also expanded from what was previously reported. Cracks on the inside of the west wall was also reported for the first time. It appears some of this is building degradation and some is new findings as they gain access to more areas of the building for closer inspections.
The August 2012 report in Japanese shows the west wall [...] 4th floor as failed with the entire 3rd floor now failed with half of the 2nd floor now partially failed. In May 2011 the 2nd floor was assumed sound. This newly declared partially damaged area is above the garage door opening TEPCO has attempted to photoshop out of recent images.
