On April 16th 2011, approx. 400ml of water was taken as sample from the
water flowed from the spent fuel pool to the skimmer surge tank*, to check
the condition of the water in the pool, in order to reflect to the design
of temporary cooling equipment which is being considered to introduce for
the spent fuel pool of Fukushima Daiichi Nuclear Power Station Unit 2.
From the result of nuclide analysis of the water of skimmer surge tank
which was sampled, radioactive materials have been detected as shown in
the attachment.

Detail valuation of the result will be conducted hereafter.

                                                                       End

*Skimmer surge tank
 Two tanks installed between pool and well, in order to store the water
 overflowed from the spent fuel pool and the reactor well.
 The tank has the role of collecting materials such as waste floating in
 the spent fuel pool and the reactor well
