At around 12:42 pm on March 27, 2012, during the work to receive samples (water) for performance verification test of ALPS (Advanced Liquid Processing System) which were carried in from Fukushima Daiichi Nuclear Power Station, at Service Building of Unit 3 and 4 of Fukushima Daini Nuclear Power Station (uncontrolled area*), our employee has found the pollution due to radioactive materials on the table next to the small monitor in the check point to check the pollution of the goods when leaving controlled area.

Investigation for cause is currently underway.

The table where pollution was found and the area where pollution is suspected are set as a restricted area to prevent expansion of the pollution and are under control.

* uncontrolled area
Uncontrolled area is an area where control is necessary to prevent unnecessary exposure to radiation and to prevent expansion of the radioactive pollution by radioactive materials and it is outside the controlled area.

 

* We would like to make corrections to the press release published on March 27, 2012. We apologize for any inconvenience and would like to correct from the expression of "for analysis" to "for performance verification test of ALPS (Advanced Liquid Processing System)". (April 13, 2012)
