High radiation means delays in decommissioning crippled Fukushima reactors
The decommissioning process at the Fukushima No. 1 nuclear power plant faces a further obstacle after Tokyo Electric Power Co. said radiation readings in the containment vessel of the No. 2 reactor were at fatal levels on March 27.
[...] 72.9 sieverts was recorded about 4.2 meters from the bottom of the vessel.
After the Fukushima nuclear disaster flared, the highest radiation level recorded was about 10 sieverts per hour last August around piping near the main exhaust duct of the No. 1 and No. 2 reactors.
[...] The latest reading is not only much higher but reinforces the possibility that the decommissioning process will be prolonged. [...]
Decommissioning was initially expected to take around 30 years, but that estimate will likely now have to be revised.
