Spent fuel pool of Reactor 5 suspended for coolant system failure / Tepco “We have 9 days to go”

On 7/6/2014, Tepco announced the coolant system of Reactor 5 had a leakage failure to stop cooling the spent fuel pool.

Reactor 5 is shut down with Reactor 6, however they still need to keep cooling down the reactors and the spent fuel pools.

From Tepco’s statement, the troubled coolant system is a seawater pump of a nuclear reactor auxiliary machine cooling system, which is to exchange the heat with the direct coolant water. They found approx. 1.3 t of coolant seawater leaked in Reactor5 building.

At 13:10 of 7/6/2014, Tepco suspended the coolant system of the spent fuel pool of Reactor 5 in order to stop the leakage.

The leaking point was a hole of 3mm diameter flow regulating valve.

The pool temperature was 23℃ when suspended. Tepco states they still have 9 days until it reaches the safety limit of 65℃.

However, it is not clear how they are going to fix the leaking point. Tepco hasn’t announced their next measures after the 10th day.
