‘Duct tape, wire nets’ were used to mend Fukushima water tanks - worker

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.
“I couldn’t believe that such slipshod work was being done, even if it was
part of stopgap measures,” Uechi told The Asahi Shimbun.
Among other makeshift cost-cutting measures was the use of second-hand
materials. Uechi also said that wire nets were used instead of reinforcing
bars during the placement of concrete for storage tank foundations. In
addition, waterproof sheets were applied along the joints inside flange-type
cylindrical tanks to save on the sealing agent used to join metal sheets of
the storage tanks. Rain and snow had washed away the anti-corrosive agent
applied around clamping bolts, reducing the sealing effect, Uechi added.
According to the Fukushima worker, many of the tanks were later found to be
leaking contaminated water.
On Saturday, workers at Fukushima Daiichi began preparations for cleaning
the plant’s drainage system that contains more than 20,000 tons of water
with high levels of radioactive substances, according to Tokyo Electric
Power Company (TEPCO), the plant’s operator responsible for the clean-up.
In August, TEPCO detected 2.35 billion becquerels of cesium per liter in the
water located in underground passages which is leaking into the groundwater
through cracks in the drainage tunnels. The normal level is estimated at
150 becquerels of cesium per liter, according to EU.
The workers are to set up the special equipment to freeze the ground around
the reactors, according to TEPCO. The plan includes plunging tubes carrying
a coolant liquid deep into the ground that would freeze the ground solid so
that no groundwater could pass through it.
Fallout researcher Christina Consolo told RT that the contaminated water
issue at the plant is a very difficult problem to solve.
“The water build-up is an extraordinarily difficult problem in and of
itself, and as anyone with a leaky basement knows, water always 'finds a way
.’
She added that as “the site has been propped up with duct tape and a kick-
stand for over two years. Many of their 'fixes' are only temporary, as there
are so many issues to address, and cost always seems to be an enormous
factor in what gets implemented and what doesn't.” | l****i

这种事情也能给鬼子拍上，不得不佩服啊

维修。日本人精明就精明在这个地方了。 | J******n
发帖数: 183 | 6 能不能请西海岸各地的使领馆每天定时公布一下检测到的核污染指标啊？只用中文的也
行啊，也不会引起当地居民的恐慌。或者请其他国家的使领馆代为公布也可以啊。 |
