10 July 2011, Tokyo Electric Power Company has stopped its water decontamination operation, again.  This time it’s due to chemicals leaking from the system.  The chemicals are used to absorb radiation from the water.

According to NHK, TEPCo is blaming the new leaks on “non-durable” materials used to build the decontamination unit.  Basically they used parts that could not withstand the pressure, radiation and chemicals in the system.

Many reports from Japan have been confusing, because they’ve referred to problems in the ‘cooling’ system, when they mean decontamination system.  This could be because the two systems are interconnected.
