Press Release (Apr 30,2011)
Detection of Radioactive Materials from Subsurface Water near the Turbine Buildings of Fukushima Daiichi Nuclear Power Station
On March 28th 2011, we were advised from Nuclear Safety Commission of
Japan to enhance the sampling survey regarding water in underground floor
of the turbine building of Fukushima Daiichi Nuclear Power Station. In
order to verify any leakages to underground and sea, and safety, we have
been implementing the sampling survey of subsurface water and seawater.

Regarding sampling surveys of sub-drains, based on the instruction from
NISA on April 14th, we continue to conduct same kind of sampling survey
three times a week, and inform the result on the next day of the survey.
                                                  (Previously announced)

On April 29, 2011, we had conducted sampling surveys regarding sub-drains
(subsurface water obtained and managed in the site) near the turbine
buildings of Fukushima Daiichi Nuclear Power Station. Today, we informed
Nuclear and Industrial Safety Agency (NISA) and the government of
Fukushima Prefecture of the results, since radioactive materials were
detected as shown in the attachment.
