About two drops of water leakage per second has been detected since
last July by the leakage detection system of the PWR fuel storage pool
in our spent fuel acceptance and storage facility.
The pool's detection system has detected water presence every year since
1996. They have been regarded as dew condensation caused in a space
between the pool lining and concrete wall rather than leakage of pool
water because they stopped in about three or four months. This time,
as water presence is still detected after five months have passed, we
have decided to investigate the cause of water presence as described
in the attached document.
The findings of investigation will be reported to the central government
and the local governments concerned, and also publicly announced.
The water discharged from the leakage detection system has been properly
treated by our liquid waste treatment facility, causing no concern about
environmental impact.
