Workers Entered Fukushima II (Daini) Reactor 4

While the attention is on Fukushima I, TEPCO has been quietly working on Fukushima II Nuclear Power Plant located in Naraha-machi and Tomioka-machi.

On August 29, workers entered the Containment Vessel of Reactor 4 at Fukushima II for the first time since March 11. No details of the work inside the Containment Vessel have been released by TEPCO yet.

From NHK News (8/29/2011):


Workers entered the Containment Vessel of Reactor 4 at Fukushima II Nuclear Power Plant to check the damages if any and measure radiation levels.


It is the first time after the accident that anyone entered the Containment Vessel of any reactor at either Fukushima I or Fukushima II.


At Fukushima II, after the automatic shutdown of all 4 reactors after the March 11 earthquake, part of the cooling systems that use seawater to cool the reactors was broken by the tsunami in three of the reactors including Reactor 4, and the reactors were not cooled sufficiently.


Reactor 4 was brought to a cold shutdown 4 days after the quake using the cooling system with external power supply. TEPCO determined that the condition of the reactor was stable, and sent about 10 workers inside the Containment Vessel to conduct the survey of the inside.


The reactor pressure rose temporarily in Reactor 4 after the quake. TEPCO is going to check for damages as well as measure the radiation levels and temperature inside.


It is the first time since the accident that anyone entered the Containment Vessel in Fukushima I or Fukushima II. TEPCO says it will decide on the necessary work to be done inside the Containment Vessel, once it gets the result of the survey on August 29.

TEPCO is not just working on the Containment Vessel at Fukushima II by the way. It's been working on the heat exchanger for Reactor 4 also, as evidenced by TEPCO's announcement that one worker from a TEPCO affiliate company fell ill due to excess heat in the heat exchanger building while he was re-routing the temporary cable.

What is TEPCO up to? Restart Fukushima II? That's what the mayor of Naraha-machi wants TEPCO to do.

I also wonder whatever happened to the 3000 tonnes of contaminated water in the basement of the plant.

All this danger with nuclear power is too deadly for everyone....especially the workers!

Fukushima II Nuclear Power Plant will not be restarted. since it is not official disaster and time has passed it is probably ok for yakuza to get workers in there
