Title: Camera inserted in Fukushima No.4 reactor
Date: Friday, March 16, 2012 21:21 (JST)
Debris from a hydrogen explosion and large volume of floating objects were observed inside the Number 4 reactor [...]
Wreckage, which included two pieces of long, thin sheets, was seen at the bottom of the reactor and a large number of floating white objects were also observed.
Similar floating matter was also found in the spent fuel pool inside the building, causing the pool’s visibility to fall from 5 meters last month to one meter now. [...]
It says removal of the spent fuel from the pool requires a visibility of at least 7 meters and that it will investigate how the floating matter was created.
