Pre-nuclear blasts in N Korea

North Korea has conducted 70 high-explosive tests linked to nuclear weapons development, South Korea's spy chief was quoted as saying last night.
The claim was made just hours after the Prime Minister, John Howard, began reining in Australia's tough talk on North Korea, amid warnings that military threats could provoke a nuclear confrontation.
A senior source in Seoul said that Ko Young-Koo, a National Intelligence Service director, had told parliament: 'We have also noticed high-explosive tests being conducted in Yongdok district in Gusong City in
North Pyongyang and we have been keeping track of the movement."
He also said that North Korea had apparently begun reprocessing spent nuclear fuel rods, a program that could yield enough plutonium for half-a-dozen atomic bombs within months.
Conventional high explosives are used to trigger atomic blasts. When detonated, they can compress a plutonium core and set off a compact nuclear blast.

SEOUL, South Korea (AP) - South Korea said Wednesday the communist North has reprocessed a small number of spent nuclear fuel rods, an important step in making weapons. The report came as North Korean envoys warned that the ``black clouds of a nuclear war'' are approaching.
The developments are likely to escalate the crisis over North Korea's suspected development of nuclear weapons.
South Korea's National Intelligence Service said in a report to the National Assembly that it believed North Korea has reprocessed ``a small portion'' of the 8,000 spent fuel rods at its nuclear facilities at Yongbyon.
