Ever since Tokyo Electric Power Company installed a water decontamination and recirculation system, they’ve had problems after problems. Now the entire system has crashed.
The system includes filters and pumps designed in the United States and France. The idea is to decontaminate the massive amount of radioactive water flooding into the basements of the reactor buildings, then re-use that water to cool the unstable reactors.
The most common problem, in the many weeks since it’s installation, has been the fact that the decontamination part is not working well, the radiation levels are not being reduced to a level TEPCo would like (this is another proof that radiation levels coming out of the reactors are much higher than TEPCo would like to admit).
The next most common problem is that pumps keep failing. This time all the pumps have failed, including the back up pumps.
Beginning Thursday, 04 August 2011, pumps began failing. By Saturday, 06 August, all the pumps were down. As usual TEPCo does not know why, and is investigation to find out why!!!
TEPCo is planning on hooking up a Japanese designed filters and pumps to the system, as if that’s the solution.
