Deterioration in cooling system at Fukushima nuclear plant

Injecting water to reactor1 ~ 3 decreased again Fukushima Diary by Mochizuki   September 14th, 2012 ·   The coolant system of Fukushima plant is getting deteriorated. Tepco has been struggling to control water injecting system since 8/30/2012. (cf.Tepco struggling to control the coolant system, “Adjusted the valves 7 times for 2 days”)

They announced that they solved the problem by eliminating the suspended materials on 9/13/2012, but on 9/14/2012, they had the problem of decreasing water amount to inject again.

In reactor1, water injection decreased by 10% from 21:00 of 9/13 to 1:00 of 9/14/2012.

In reactor2, it decreased from 1:00 to 7:00 of 9/14/2012.

They are trying to increase the water amount.

Tepco is still assuming it is due to the substances which flowed into the buffer tank and got stuck in the flow rate adjustment valves in the downstream side, narrowing the water flowing channel as a result.

The false report that Tepco reported the problem was solved in is below. [Link]….. http://fukushima-diary.com/2012/09/injecting-water-to-reactor1-3-decreased-again/#.UFOKy52ScB4.facebook
