» 20 or more second hand water tanks are used for storing contaminated water

Roughly 20 or more second water tanks holding radioactively contaminated water at the Fukushima No. 1 Nuclear Power Plant are used, according to TEPCO.

In August 2013, highly radioactive water was found leaking from one of the plant’s tanks. A TEPCO representative refused to comment on whether that tank was one of the used ones.

The secondhand tanks and the tank that leaked are all types assembled by bolting steel pieces together, known as “flange” models. TEPCO has said flange tanks can be used for five years.

However, an inside source with a Tokyo company that supplied TEPCO, “We don’t guarantee the tanks for five years as a company, and they are not made to be completely leak-proof in the first place.”

According to the source, TEPCO ordered tanks from the company in Tokyo’s Chuo Ward after the March 2011 Great East Japan Earthquake to store contaminated water, but since it would take too much time to make new ones, in around May 2011, the manufacturer supplied TEPCO with 20 to 30 used flange tanks — mud-storage tanks that it had been renting out to businesses such as construction firms.
