Yesterday I speculated that Tokyo Electric Power Company probably installed their water radiation filters backwards.  Today NHK reporting that incorrect settings of the system are the cause of TEPCo’s problems.

At least twice TEPCo had to stop their decontamination of water, at Fukushima Daiichi, because they were getting the reverse effect; an increase in radiation levels in the water.  Another time they stopped because they broke a water pump.

It turns out all those problems were caused by the incorrect setting of valves.  The result was that less than half of the filter chambers were being used.  TEPCo blames their throwaway workers for misunderstanding the “open” and “shut” indicators on the U.S. designed system!
