[As
for the Fukushima Daini Nuclear Power Station]
After
the earthquake occurred at 5:18 pm on December 7, 2012, we have
conducted checkups at the Fukushima Daini Nuclear Power Station, and
have found there was no problem.
Since
we had found positive pressure in the reactor building of Unit 1, we
have started Stand by Gas Treatment System* (the pressure was 0.05
kPa at that time of the start), and confirmed negative pressure in
the reactor building. The negative pressure has been kept currently.
We will conduct inspections for the cause of this matter.
The
fluctuation of the monitoring post readings is being maintained
within the range of normal fluctuation before and after the
earthquake and currently no radiation impact to the outside of the
power station has been reported due to the earthquake.
