Treated water of The Tokai Reprocessing Plant used for cooling water and fire fighting water, is supplied by the steel pipes. These pipes are laid down under the ground or in the trench. Treated water had leaked, because the part of the underground pipe flange corrosion. The cause of this breakage was presumed that the pipe flange has been loaded the stress continuously. The stress generated depend of that the underground pipes sank with the ground subsidence by influence of the 2011 earthquake of the ...

The automatic fire alarm system installed in the Tokai Reprocessing Plant consists of more than 5,000 detectors in about 40 facilities for the moment. In this system, 51 non-fire cases have occurred for about 8 years from January 2 001 to May 2009. and about half of these cases was due to the condensation of water vapor generated on the sensor. Therefore, the prevention of condensation is necessary to reduce such false alarms, and the measure for prevention o f condensation has been taken by installing a m...
