Fukushima Daiichi - Update

Tokyo Electric Power Co. (TEPCO) estimates it will take up to nine months to stabilize the Fukushima Daiichi nuclear power plant. A plan released Sunday breaks the project into two steps, the first taking up to three months, the second up to six months more.

According to the company’s “Roadmap Towards Restoration,” TEPCO plans to:

•     Fill the containment vessels of reactors 1 and 3 with enough water to cover the fuel in the reactors while it decides the best course of action to repair the damaged containment vessel of reactor 2. The goal is to lower
the temperature of the water inside the reactors to below boiling.

•     Install heat exchangers to help cool the reactors. TEPCO continues to inject water into the reactors to prevent overheating. TEPCO also continues to spray water onto the used fuel storage pools as needed.

•     Use giant covers with filters to enclose the reactor buildings and control the release of radioactivity.

•     Install additional water storage tanks and purification facilities to process the highly radioactive water that has accumulated in the plant buildings and nearby concrete enclosures. The decontaminated water then
will be used to cool the reactors. Radioactive water that has accumulated in turbine room basements is  hampering work to restore cooling operations.


  1. thanks for the info as the news is pretty much silent about this now, as that new international disaster, known as the royal wedding, has upstaged everything else....


  2. Ken, thanks for the update. Just like Mrs. Miss A says, the media has turned to other things now.

  3. I believe they'll take all the steps they're promising.


Tell Me What You Think, Don't Make me go Rogue on you :o)
