As TEPCO began preparations for the cleaning of the drainage system with tons of leaked radioactive water at the Fukushima power plant,a former employee reveals the reason for so many leaks was cost cutting measures such as using duct tape,Asahi reported.
Yoshitatsu Uechi, auto mechanic and tour-bus driver, worked at the devastated nuclear power plant between July 2 and Dec. 6, 2012, according to Asahi Shimbun report. He was one of the 17 workers from Okinawa Prefecture sent to work at the crippled nuclear plant in 2012 to create new places to store contaminated water.
The earthquake in March 2011 triggered a tsunami that hit Japan’s coast, damaging the Fukushima Daiichi plant. The catastrophe caused the meltdown of three nuclear reactors at the facility, leading to the worst nuclear disaster since Chernobyl.
The water used to cool the reactors has been leaking into the soil and contaminating the ground water on the premises of the nuclear facility, with some escaping into the Pacific Ocean.
The 48 year old Japanese man said that workers were sent to various places in Fukushima, including an area called H3 with high radiation levels.
In one of those cases in October 2012, Uechi was given a task to cover five or six storage tanks without lids in the “E” area close to H3 as it was raining, the Japanese paper reported. When he climbed to the top of the 10-meter-high tank Uechi found white adhesive tape covering an opening of about 30 centimeters. After using a blade to remove the tape he applied a sealing agent on the opening and fit a steel lid fastening it with bolts. According to instructions he was to use four bolts, though the lid had eight bolt holes.
According to the employee, his colleagues later told him that the use of adhesive tape was a usual practice to deal with the problem of sealing in radioactive water.
