Tepco struggling to control the coolant system, “Adjusted the valves 7 times for 2 days”

 

On 8/30/2012, the injection water for reactor 1~3 decreased all of a sudden. (cf. Sudden decrease of injecting water for reactor1~3, cause not known)
Tepco announced they fixed it but the sudden decrease of water injection happened once again on the same day.
Even on 8/31/2012, It’s still decreasing intermittently but they haven’t verified the reason yet.

Tepco adjusted the valves twice on 8/30/2012, but because the trouble was still going-on, they adjusted the valves 5 times from 0:00 to 15:00 of 8/31/2012.
According to Tepco’s report, water temperature has not changed. Because no water leakage is confirmed, they presume trashes are stuck in the valves to control water amount. They are to clean the inside of the valves.
