The plant
operator described No. 3 -- the
only reactor at that uses
plutonium in its fuel mix -- as
the "priority". Plutonium, once
absorbed in the bloodstream, can
linger for years in bone marrow
or liver and lead to cancer.
If cooling
operations do not proceed well,
the situation will "reach a
critical stage in a couple of
days", said an official with the
government's Nuclear and
Industrial Safety Agency.
The situation
at No. 4 reactor, where the fire
broke out, was "not so good",
TEPCO added, while water was
being poured into reactors No. 5
and 6, indicating the entire
six-reactor facility was now at
risk of overheating.
"Getting
water into the pools of the No.3
and No.4 reactors is a high
priority," Said Hidehiko
Nishiyama, a senior official at
Japan's Nuclear and
Industrial Safety
Administration.
"It could
become a serious problem in a
few days," he said.
UNPRECEDENTED
CRISIS, SAYS EMPEROR
Japanese
Emperor Akihito, delivering a
rare video message to his people
on Wednesday, said he was deeply
worried by the crisis which was
"unprecedented in scale".
"I hope from
the bottom of my heart that the
people will, hand in hand, treat
each other with compassion and
overcome these difficult times,"
the emperor said.
Panic over
the economic impact of last
Friday's massive earthquake and
tsunami knocked $620 billion off
Japan's stock market over the
first two days of this week, but
the Nikkei index rebounded on
Wednesday to end up 5.68
percent.
The Tokyo
Stock Exchange and the Financial
Services Agency plan to keep the
stock market open despite calls
for a halt to trading, mainly
from foreign financial
institutions, the Nikkei
business daily said.
TSE President
Atsushi Saito said the exchange
"will continue to provide
investors with an opportunity to
trade", calling it "an important
piece of social infrastructure".
"If we put a
stop to trading, it will be seen
as a confirmation of the
concerns among foreigners and
could trigger panic," a senior
TSE official was quoted as
saying by the Nikkei.
Estimates of
losses to Japanese output from
damage to buildings, production
and consumer activity ranged
from between 10 and 16 trillion
yen ($125-$200 billion), up to
one-and-a-half times the
economic losses from the
devastating 1995 Kobe
earthquake.
Damage to
Japan's manufacturing base and
infrastructure is also
threatening significant
disruption to the global supply
chain, particularly in the
technology and auto sectors.
EMBASSIES
URGE CITIZENS TO LEAVE
Scores of
flights to Japan have been
halted or rerouted and air
travelers are avoiding Tokyo for
fear of radiation. On Thursday
the U.S. Embassy in Tokyo urged
citizens living within 50 miles
of the Daiichi plant to evacuate
or remain indoors "as a
precaution", while Britain's
foreign office urged citizens
"to consider leaving the area".
