Fukushima Daiichi NPS Prompt Report 2013

Pump capacity and storage capacity have been increased, and other preventive measures have been taken

 
TOKYO-Oct. 25, 2013.  Typhoon No. 27 (Francisco) is expected to approach Japan and could affect Fukushima Daiichi NPS this weekend.  To prepare for the typhoon, TEPCO has increased water transfer capacity and water storage capacity to prevent overflow of the accumulated water in the dikes* by installing additional high-capacity pumps (60 m3×19 units) and utilizing underground reservoirs and other vacant tanks (approximately 9,000 m3).  In addition to these advance preparation, TEPCO has been taking extra caution in the tank areas where relatively higher contaminated water is accumulated in; such as installing iron plates on the top of the dikes to make the dikes taller and installing eaves trough on the top of the tanks to prevent rainwater fall down into the dikes.  TEPCO is confident that there will be no overflow from the dikes by the typhoon.
