On May 8th, 2011, we took approx. 40 ml of the water in the spent fuel
pool of Unit 3 at Fukushima Daiichi Nuclear Power Station using the
concrete pumping vehicle to check the condition in the pool.
As a result of the nuclide analyses of radioactive materials contained in
the sampled water, radioactive materials were detected as described in the
attachment. Accordingly, we have reported the result of the analyses to
Nuclear and Industrial Safety Agency and the government of Fukushima
Prefecture on May 10th.
We will make detailed evaluations later.
