We have received directive document from NISA "Regarding Response to the
Accumulated Water Containing Radioactive Materials Found in Trench at
Fukushima Dai-ichi Nuclear Power Station (Direction)" on December 19 with
regards to the fact that we found the accumulated water in the trench
between process main building and miscellaneous solid waste volume
reduction treatment building(high temperature incinerator building) in the
centralized radiation waste treatment facility at Fukushima Daiichi
Nuclear Power Station on December 18, which contains radioactive materials.*1 
                                (Previously reported on December 19, 2011)

In accordance with the directive document, on January 6, we have reported
to NISA regarding the situation of "1. To promptly transfer the water
accumulated in the trench to the equipment that can appropriately manage
the water", "2. To investigate the inflow route of the water accumulated
in the trench and to consider the water stoppage measures" and "4. To
formulate and implement the patrolling visual inspection and checkup plan
to check the existence of accumulated water containing radioactive
materials in other trenches".
                                  (Previously reported on January 6, 2012)

Thereafter, while we have been implementing inspection of trenches within
the site of Fukushima Daiichi Nuclear Power Station and have been
determining existence of accumulated water and have been investigating
water level and density of radio active materials, today, we have received
directive document from NISA "Regarding Response to the Accumulated Water
Containing Radioactive Materials Found in Trench at Fukushima Dai-ichi
Nuclear Power Station (Further Direction)"*2 

In accordance with the further direction, we will take smooth response and
report to NISA in a timely manner.

                                                                       End

On December 18, 2011, the Nuclear and Industrial Safety Agency (NISA)
received a report from your company stating that the accumulated water
containing radioactive materials was found in a trench at Fukushima
Dai-ichi Nuclear Power Station.
In light of the event of a large amount of water containing radioactive
materials accumulated in the trench, NISA requests your company to take
measures as described below and to promptly report the results of the
measures to NISA in order of implementation.

Required Items
1.To promptly transfer the water accumulated in the trench to the
  equipment that can appropriately manage the water;
2.To investigate the inflow route of the water accumulated in the trench
  and to consider the water stoppage measures;
3.To investigate the cause of the event that radioactive materials are
  contained in the water accumulated in the trench as well as to take
  recurrence prevention measures to prevent the water containing
  radioactive materials from flowing into the trench;
4.To formulate and implement the patrolling visual inspection and checkup
  plan to check the existence of accumulated water containing radioactive
  materials in other trenches.
