March 24 Watching TV images of workers
frantically dousing the reactors of Japan's earthquake-wrecked
nuclear plant with water, one man realised he was uniquely
placed to help out: he had on hand a truck-mounted pump bigger
than any other in the land.
By Wednesday this week a bright red Putzmeister pump
normally used to pour concrete was towering 58 metres (190 feet)
over the burnt-out remains of reactor No. 4 at the Fukushima
Daiichi plant, filling its spent-fuel pool with sea water at a
rate of 160 cubic metres (5,650 cubic feet) an hour.
But getting to that point in the chaotic days that followed
the March 11 earthquake and tsunami was no easy matter for
Hiroshi Suzuki, head of the Japan branch of a German firm that
makes the behemoths.
For one thing the pump was on a ship off Tokyo in transit to
a client when the disaster struck, knocking out the plant's
Then there was the problem of getting government permission
to take it up to the nuclear facility 240 km (150 miles) north
of Tokyo as concern mounted that it could spew radioactive
material into the atmosphere.
"I contacted the prime minister's office with information
about our equipment last Tuesday, but there was no response for
about two days," Suzuki said in a telephone interview. "They may
have thought they could manage with their water trucks and fire
Suzuki was eventually summoned to the prime minister's
office and given an emergency order allowing him to bring ashore
the pump truck, which is so large it is illegal on Japanese
roads in normal circumstances.
After the client was persuaded to part with the equipment,
he and a colleague drove the pump north of the exclusion zone
surrounding the unstable reactors, leaving Suzuki's worried
Australian wife, Juliane, and two teenage children in Tokyo.
There, he trained contractors for the plant's operators to
run the machine and stood by on tenterhooks until it finally
cranked into action.
"Honestly speaking, I just did what was necessary, but I was
relieved when I heard it was successful," he said. "We've been
told it went well today and yesterday, and radiation levels have
The mission was a peculiarly personal one for Suzuki, who
was born in nearby Sendai and has two relatives still
unaccounted for after the March 11 disaster, which has left
nearly 26,000 people dead or missing.
Coincidentally, Putzmeister concrete pumps were among those
used to seal in the Chernobyl reactor after it exploded in
Ukraine in 1986, and sightings of the truck led to media
speculation that Japan was planning to do the same in Fukushima.
Of course, Suzuki says, if the decision is ever made to go
ahead and build a similar sarcophagus at Fukushima, the
Putzmeister pump can help with that, too.
