LDALL QUAKE 2
Combating the risk of overheating at No.3 reactor's
storage pool, technicians were trying to fix a high-power line
from the national grid to No.2 even as dumping of cool water
continued from helicopters and water cannon trucks.
The Tokyo Fire Department was also roped in to spray
water and the pools storing spent fuel rods.
Radiation readings at the plant have followed a downward
path today but TEPCO stopped short of calling the move a
trend, Kyodo reported.
The radiation level at 11 am dropped to 265.0
microsievert per hour from 351.4 microsievert per hour at
12.30 am on Thursday. The latest radiation levels are 500
microsiever per hour, the threshold beyond which the operator
is required to report an emergency to the government, the
agency said.
Chief Cabinet Secretary Yukio Edano said the radiation
amounts near the plant "do not pose immediate adverse effects
to the human body".
"We are simply doing our best to prevent the incident at
the Fukushima Daiichi Nuclear Power Station from affecting
public health and help as much as possible in preventing the
situation from deteriorating further," he said, adding that
authorities were coordinating with the US as to what help
Washington "can provide and what people really need."
Plumes of smoke or steam were seen rising from three of
the buildings, suggesting their pools situated outside reactor
containment vessels were boiling, Kyodo said quoting
authorities.
SDF fire trucks shot 50 tonnes of water at a spent fuel
pool of the No.3 reactor, a day after military helicopters
dumped water in an attempt to prevent a meltdown of fuel rods,
Kyodo news agency reported. The Tokyo Fire Department is also
expected to join the operation at the Fukushima plant.
On the efforts to cool down overheating reactors, Edano
said the fire department's trucks may be pressed into action
to help douse a spent nuclear fuel pool at the No.1 reactor.
Although it does not pose as imminent a threat as the No.3 and
No.4 reactors of releasing radioactive material into the air.
Edano said radiation levels near the Fukushima plant "do
not pose immediate adverse effects on the human body."
The confirmed death toll in the last week's disaster has
reached 6,911, exceeding the 6,434 marked in the 1995 Great
Hanshin earthquake, the National Police Agency said. The total
number of dead and unaccounted for in the largest natural
catastrophe in post-war Japan touched 17,227.
Meanwhile, 21 people died after being transferred to
evacuation centres in Fukushima Prefecture from a hospital in
accordance with an official directive issued due to the
trouble at the nuclear plant, Kyodo said, adding they included
elderly patients.
