Translation by Fukushima Diary
From the picture of Tepco, they are removing the brace of reactor 4. If another earthquake hits the plant now, it can’t stand the horizontal oscillation.
[Fukushima Diary: He also points out the pillar for the pool may weaken the building itself.]
About reactor 4. The pillar might help to support the spent fuel pool but might add too much weight to the building.
It’s rational for them to take away the ceiling truss, but they look like they are taking out even the horizontal joist. Without a proper reinforcement, it is almost like a gamble. If another earthquake hits the reactor 4, it could collapse the building.
Considering the explosion, radiation, heat and humidity, the constructional material must have been so weaken because of oxidation. and it’s leaning. If Tepco outsource it all to a construction company, they might not take those risks into consideration.
