French Defence Minister Michele Alliot-Marie said
yesterday that the Democratic People's Republic of Korea (DPRK) reported nuclear
bomb test produced an explosion so small that if indeed nuclear, it was a
failure.

French experts have not yet determined the precise cause of the DPRK's
explosion, she told French radio, but French, US and other scientists detected
that it was of "relatively limited size."
"In any case, if this was a nuclear explosion, it would be a case of a failed
explosion," she said, adding "that doesn't change anything about the severity of
things" because it would still hurt efforts to bring stability to East Asia.
French experts, working from international seismological data gathered at the
time of the blast, say the explosion mustered a force equivalent to that caused
by 500-1,000 tons of TNT.
However, Russian Defence Minister Sergei Ivanov initially said the blast had
a destructive power of between 5,000-15,000 tons of TNT. The atomic bomb that
struck Hiroshima, Japan, on August 6, 1945, also had a force of about 15,000
tons.
Xavier Clement of France's Atomic Energy Commission said he could not explain
how the Russians could have come up with that figure.
"It's a hypothesis, not shared by us and other countries who also possess
this type of high-precision analysis," he said in a telephone interview. "(The
information) we are giving right now is credible."
Clement said the Comprehensive Nuclear Test Ban Treaty Organization, which
has some 200 stations worldwide that can monitor nuclear tests, has not yet
provided member country France with any radiological data that could help
determine the type of explosion.
"What's important is to determine is whether this was chemical or nuclear,"
Clement said, saying that seismological data was being collected to try to
differentiate between the two. "It's possible that we never will."
Alliot-Marie, who relies on the atomic commission for her information on the
test, on Monday was among the first Western policy makers to suggest it could
have been a dud.
The comments yesterday were her strongest so far about the possibility of a
failed test, suggesting that that theory was gaining credence among French
experts.
Although the blast from the nuclear weapons test was strong enough to send
seismic waves as far as Japan's main island, verifying exactly what happened
could take several more days, if not weeks, officials said yesterday.
"We are still currently investigating various matters and we will continue to
work on confirming the facts," said Japan's chief government spokesman, Yasuhisa
Shiozaki. Shiozaki has said officials are not even at the stage when they can
predict how long the verification process will take.
US military officials, meanwhile, remained quiet, confirming only that they
are monitoring the situation. The United States has WC-135 reconnaissance planes
deployed on the southern Japan island of Okinawa that can sniff out radiation in
the air and glean other data on the test.
Washington also regularly flies U-2 spy planes out of an air base in the
Republic of Korea (ROK).
Yesterday, a British Royal Air Force VC-10 refuelling plane arrived at Yokota
Air Base, just outside of Tokyo, to assist in the verification effort under the
auspices of the United Nations. It later flew to Kadena Air Base on Okinawa,
where the WC-135s are based.
"The UK is assisting in international operations in respect to verifying the
DPRK's nuclear tests," said Clive Hughes, the press attache for the British
Embassy in Tokyo. He refused to provide further details.
Though it would seem easy to confirm a nuclear explosion, the technical
challenges can be daunting.
The White House has acknowledged there is a "remote possibility" that the
world never will be able to fully determine whether the DPRK succeeded in
conducting the test.
A leading Japanese nuclear expert agreed.
"It is possible with a relatively small underground blast that there would be
no significant release of radiation," said Hideshi Takesada, of the National
Institute for Defence Studies, a branch of Japan's Defence
Agency.
