Who
Really Runs Fukushima Daiichi?
30
November, 2013
Much
has been made about the contractor system at Fukushima Daiichi, the
worker abuses and cut rate construction. This only looks at one
aspect of the contractor system at the plant. Tasks like tank
construction have been given out to layers of subcontractors but
these subcontractors only do some of the work at the plant. Much of
the work falls to what are called prime contractors. These are
companies like Toshiba, Hitachi-GE or Kajima. The work they do at the
plant is much more significant and frequently flies under the radar.
TEPCO
reports work done at the plant including some of the dangerous
inspection work to attempt to gain information about the melted down
reactors. TEPCO rarely says exactly who is doing this work, if they
are TEPCO employees or prime contractors. Workers Happy and Sunny
both worked for prime contractors at Daiichi. Both mentioned over
time the nature of the projects they worked on including varioius
efforts to run scopes into the reactor buildings and efforts to clean
off units 3 and 4. These two workers were at the plant through the
initial disaster but have reached their maximum exposure this year so
they are no longer involved in the hands on work at the plant.
Greenpeace
has called
for “GE” to be held accountable
for the flawed design of the reactors at Fukushima Daiichi. This
seems to ignore the reality that “GE” is still there and largely
in charge of the disaster response and profiting off of it.
Hitachi-GE
This
company has been a major player in the response at the plant.
Hitachi-GE is frequently names as just “Hitachi” but it is the GE
nuclear company as it exists today in both Japan and the US. This is
the company that designed and mostly built the reactors at Fukushima
Daiichi. They have also had a heavy presence in the maintenance and
repair of these reactors over the decades. This list of open
proposals on Hitachi-GE’s website shows the
considerable extent
to which they are running the response to the disaster and
decommissioning efforts. Hitachi is doing everything from inspection
efforts to decommissioning planning based on their requests for
proposals on their website. Hitachi is also frequently branded on
these efforts already underway though TEPCO declines to admit who is
doing the work. Hitachi developed the SoRa
robot.
They were involved in the boat
robot project.
Hitachi admits involvement in
just about every aspect
of the response at Daiichi. Hitachi-GE appears to admit their
involvement in the fuel removal work at Unit 4
in this detailed presentation they give at Oak Ridge.
Shimizu
Corp
This
large international construction company
installed the tent cover on unit 1
at Fukushima Daiichi. Shimizu was also involved
in supplying the defective bolt together tanks
for the plant, it appears much of the actual installation work was
done by the networks of sub contractors. Shimizu has also been
involved in the contaminated rubble removal
at the plant.
Kajima
Corporation
Kajima
is involved
in the contaminated rubble removal at
the plant. Kajima was involved in the
construction of dorms/shelters 2km from the plant
that did not meet radiation resistance standards or became
contaminated after they were built. The company is tasked with
constructing
the ice wall
to be installed at the plant. An autonomous
heavy equipment system
used to clean debris off of unit 3 was developed by Kajima. More
on this system
can be found here.
Taisei
Corporation
Taisei
is involved
in the contaminated rubble removal at
the plant. Taisei was also involved in the flawed bolt
together tank installations.
Mitsubishi
The
company provided the retrofitting
of the megafloat that
was used to hold contaminated water early in the disaster. Mitsubishi
created
shielded and remote control heavy equipment
to be used at the plant. They have also created some
of the robots in use
at the plant like the Super Giraffe.
Toshiba
Toshiba
is building
the ALPS water decontamination system.
The SARRY
cesium absorption system
was built by Toshiba. The reactor
cooling systems
put together after the disaster were built by Toshiba. Toshiba also
created
the quadruped robot and
a
vacuum robot in
use at the plant. The initial response work at the plant to
restore electricity and repair power panels
was done by Toshiba. This appears to include the
power trucks and systems that have been plagued by rats.
Pump
restoration and air filtration systems
were also done by Toshiba. Toshiba was also involved in the initial
response in huge ways with hundreds
of engineers and a partnership
with US companies Shaw
and Babcock
and Wilcox.
Both are major players in the US nuclear industry. The company also
built radiation
shelters/dorms for workers at the plant that
were found to not be sufficient in their radiation resistance.
Obayashi
Corp
Developed
a radiation
shielding seat
for heavy equipment. The company is heavily involved in some of the
decontamination efforts around the prefecture.
Chiba
Inst. of Technology
While
not a contractor, the institute
has been developing robots
used at the plant such as Quince and Sakura
