N.Korea can build a nuclear bomb a year: ex US defence chief



Report: N.Korea increases flight drills despite fuel pinchSeoul (AFP) Dec 29, 2010 - A North Korean jet has crashed as the country intensified air force exercises following its attack last month on a South Korean frontline island which sent tensions soaring, a newspaper said Wednesday. A MiG fighter disappeared off radar screens last week as the impoverished communist state held unusually extensive winter flight drills, the Korea JoongAng Daily said, quoting a military source. North Korea usually keeps flight drills to a minimum because of severe fuel shortages. The paper said there had been a 150 percent increase in the number of military drills involving all three services compared to December 2009. "It shows that the North Korean military has been very tense after the attack on Yeonpyeong Island," it quoted the source as saying. A defence ministry spokesman declined to comment on military intelligence matters.

The North also carried out a corps-scale live-fire drill in response to a joint live-fire exercise by South Korea's army and air force last Thursday, Yonhap news agency said earlier this week. The news agency said the North has test-fired artillery and multiple-rocket launchers five times this month alone. The Korea JoongAng Daily said there have been frequent sightings of North Korean submarines near the disputed Yellow Sea border and artillery was moved nearer to the coast. The South has staged a series of military exercises, including one with the United States, since the North shelled the island near the Yellow Sea border on November 23 and killed four people, including two civilians.
http://www.spacedaily.com/reports/NKorea_can_build_a_nuclear_bomb_a_year_ex_US_defence_chief_999.html Tokyo (AFP) Dec 29, 2010 Former US defence chief William Perry said North Korea was capable of producing one nuclear bomb a year and that Washington should consider high-level talks to defuse tension, in an interview published Wednesday. Perry, who served as defence secretary under president Bill Clinton, told the Nikkei daily that the US government should review its policies towards North Korea and impose economic sanctions to reiterate its stance against Pyongyang's nuclear programmes.
Then, Washington should coordinate policies with Seoul and Tokyo before eventually sending a special envoy for direct talks with Pyongyang, Perry told the Nikkei.
Perry suggested former secretary of state Madeleine Albright and former US senator Sam Nunn, an expert on nuclear arms reduction, as possible candidates for such talks, the Nikkei said.
The interview was released in Japanese, with no original English text immediately available.
If North Korea dedicated all of its recently unveiled uranium enrichment facility to making weapons-grade fuel, it could build one nuclear bomb a year, Perry told the paper.
Perry said he had been briefed by American scientist Siegfried Hecker, who recently toured a new uranium enrichment plant with 2,000 uranium-enriching centrifuges at North Korea's Yongbyon nuclear complex.
The facility is likely designed for making fuel for a civilian reactor and not bombs, but there is no way to confirm whether North Korea has another facility to build nuclear weapons, Perry said.
The former defence chief said he still believed in diplomatic solutions to the North Korean crisis.

North Korea 'Enriching Weapons-Grade Uranium At A Number Of Sites' -- The Telegraph

North Korea has been enriching potentially weapons-grade uranium at up to four sites outside its main nuclear complex, South Korean intelligence has claimed.

The report of the secret additional enrichment facilities outside its Yongbon complex, first published by a South Korean newspaper, was confirmed by Seoul's foreign minister Kim Sung-hwan on Tuesday.

"It is a report based on what is still intelligence and let me just say that we have been following this issue for some time," Mr Kim said.

French enrichment plant to close in 2012 from World Nuclear News by Warwick Pipe

The Eurodif gaseous diffusion uranium enrichment plant will operate until the end of 2012 under a newly concluded agreement between Areva and Electricite de France (EdF) that sets the operating conditions for a gradual transition from production at the old plant to the new Georges Besse II centrifuge enrichment plant. The long-awaited agreement, reached under a joint strategic framework between the two companies, will see the 10.8 million SWU Eurodif plant start operating at its minimum technical capacity as soon as possible. The agreement will see EdF supply the plant's electricity for the next two years and also enables EdF to supply an additional 1000 MW of electricity to its customers over that period and guarantees a further 2000 MW beyond that date. The first stage of the first unit of Georges Besse II began operating at the end of 2009 and the second is due to start production in 2011, although the two units are not scheduled to reach full capacity until 2015 and 2016 respectively. Both groups expressed their delight that "a solution has been found to ensure the smooth transition between Eurodif and the Georges Besse II enrichment plant."

Troubling birth of a nuclear plant By MICHAEL RICHARDSON

SINGAPORE — When U.S. nuclear scientist Siegfried Hecker was taken to a new uranium- enrichment facility in North Korea's nuclear complex at Yongbyon last month, he was stunned by what he saw.
From an "astonishingly modern" control room at the plant, he looked down on neatly ordered arrays of 2,000 gas centrifuges. These high-speed spinning machines, each nearly two meters high and 20 centimeters in diameter, can be used to produce uranium fuel for nuclear power plants that generate electricity. They can also be adjusted to make the fissile cores of the most powerful thermonuclear weapons.
North Korean technicians showing Hecker and two colleagues the industrial-scale enrichment cascades housed in a building about 100 meters long insisted that the facility was configured to make low-enriched fuel for a small nuclear power reactor being built nearby.

Seoul rules out redeployment of US nuclear weapons




http://www.spacewar.com/reports/Seoul_rules_out_redeployment_of_US_nuclear_weapons_999.html Seoul (AFP) Nov 23, 2010 South Korea's defence ministry Tuesday ruled out the redeployment of US nuclear weapons on its soil as a deterrent to North Korea, a day after its minister had raised the prospect. "Redeploying US tactical nuclear weapons in South Korea would cross the line set by the policy of denuclearising the Korean peninsula," Deputy Defence Minister Chang Kwang-Il told reporters.
"We've not considered redeploying US tactical nuclear weapons and there has been no consultation with the US over the issue," he was quoted as saying by a ministry spokesman.
The Pentagon also said Monday that the United States has no immediate plans to redeploy the weapons, which were withdrawn in 1991.
Revelations over the weekend about a new uranium enrichment plant in North Korea triggered alarm in Washington, Tokyo and Seoul.
Asked in parliament Monday whether the South would consider asking for a redeployment, Defence Minister Kim Tae-Young told a lawmaker that the government "will review what you said".
His comment made front-page headlines in most newspapers Tuesday.
Chang said that the minister's comment had been taken out of context and meant that the South could consult with the US on "all possible options".
The United States still stations 28,500 troops in the South, but pulled out the atomic weapons as part of a disarmament initiative.

Surprise! North Korea Unveils a Huge New Uranium Plant [Updated] from Danger Room by Spencer Ackerman


As if the possible collapse of the Obama administration’s nuclear-arms treaty with Russia wasn’t bad enough. North Korea just unveiled a new facility for enriching uranium, possibly for nuclear bombs, all as talks to disarm the rogue state are practically dead.
Earlier this month, North Korean officials invited a former Los Alamos National Laboratories director, Siegfried S. Hecker, to its Yongbyon nuclear complex, the major installation in the north’s nuclear apparatus. They were eager to show him an “ultra-modern and clean” uranium-enrichment facility with “2,000 centrifuges… said to be producing low enriched uranium” for a new, 25 to 30 megawatt-electric light-water reactor. Those facilities “could be readily converted to produce highly-enriched uranium (HEU) bomb fuel (or parallel facilities could exist elsewhere).”
The U.S. has known about North Korea’s switch from plutonium bombs to an effort at producing weapons from highly-enriched uranium since 2002. But over the past several years, U.S. intelligence has cast doubt on the North’s ability to successfully enrich uranium, as Pyongyang’s bombs have relied on old-school, less-powerful plutonium for their potency. “The 2,000-centrifuge capability significantly exceeds my estimates and that of most other analysts,” Hecker writes. Suddenly the North may have a viable option to a second type of nuke.
This new facility has been built in barely a year, suggesting a big crash program to build more-powerful bombs than the plutonium ones currently in the North’s arsenal — even while United Nations sanctions against the North have grown more severe. And that might indicate Yongbyon is just the tip of the iceberg in a uranium program that the international community didn’t detect. “To outfit a plant with 2,000 centrifuges this quickly suggests that this may not be the first gas centrifuge plant that North Korea has built,” blogged David Albright and Paul Brannan of the Institute for Science and International Security, a leading nuclear-security think tank. “It is possible that North Korea built another plant previously and either transferred it to Yongbyon or simply built another one based on its experience of bringing the first, perhaps smaller, one into operation.”

If there’s any silver lining, Hacker writes that Yongbyon’s plutonium facilities are still being dismantled, cold comfort as that may be.
Hecker and a colleague heard that the North set up the light-water reactor after the U.S. and the North’s neighbors failed to sufficiently bribe it into disarming with heavy fuel for electricity generation. “We are willing to proceed with the Six-Party Talks and the September 19, 2005 agreement, but we cannot wait for a positive agreement,” Hecker writes the plant’s senior technical adviser told him. “We are trying our best to solve our own problems. We will convert our center to a [light-water reactor] and pilot enrichment facility. It is a high priority to develop uranium enrichment.”
The reactor is supposed to be completed by 2012, but Hecker calls that “unreasonably optimistic.” North Korean officials also claimed that they’re already producing low-enriched uranium at Yongbyon, but Hacker couldn’t verify that.
There’s been lots of speculation in the Korean and Japanese press recently that the North is about to attempt its third bomb test since 2006. An imagery analyst at Jane’s told Global Security Newswire that there have been “notable signs of excavation” at the site of the North’s first nuclear test. All this comes months after the North torpedoed a South Korean ship, killing its crew of 46 sailors, and while successor-in-waiting Kim Jong-un appears to be ridding the ruling communist party of possible rivals.
The New York Times reports that the Obama administration has sent envoys to Russia, China, Japan and South Korea to plan what to do about the new uranium-enrichment plant. It wants China, North Korea’s major patron, to exercise its economic leverage over the North, as international sanctions have clearly failed to dissuade Pyongyang from moving forward with uranium enrichment.
Daryl Kimball, the executive director of the Arms Control Association, one of the most prominent anti-proliferation think tanks in Washington, blogged on Sunday that the new North Korean enrichment facility could represent “another nuclear proliferation tipping point.” Kimball urged Obama to restart talks with the North and “outline, again and in detail, the security assurances, trade benefits, and energy support that the U.S. and other regional allies would be prepared to provide if North Korea once again halted its nuclear and missile programs, ended its proliferation behavior, and dismantled its nuclear complex.”
Like Hecker, Albright and Brannan of the Institute for Science and International Security feared that a lot of the North’s uranium-enrichment work is hidden in secrecy. “[A] centrifuge plant does not exist in a vacuum,” they wrote. “It is still unknown where North Korea researches, develops, and manufactures centrifuges.” But they speculate that the U.S. may have a new weapon in its arsenal to use against the facility: “It is possible that the North Korean plant(s) could be vulnerable to the Stuxnet worm.”
Update, 8:45 p.m.: On the Sunday-show circuit, Admiral Michael Mullen, chairman of the Joint Chiefs of Staff, didn’t exactly say that U.S. intelligence was caught flat-footed by the new uranium facility. But he gestured in that direction: “This is something we’ve been concerned about for a significant period of time,” Mullen said, “and also penetration of — of the North Koreans, in terms of intelligence capabilities, is very, very difficult.” Other U.S. officials denied any such intelligence lapse to reporters on Sunday.

U.S. Official: New North Korean Nuke Plant 'Provocative,' Defiant


U.S. officials have been aware of North Korea's efforts to go nuclear for years, but the latest report of a new highly sophisticated uranium enrichment plant is a "provocative act of defiance," a senior administration official told Fox News late Saturday.

The "stunning" show of sophistication by the North Koreans -- as witnessed by U.S. scientist Siegfried Hecker, a former director of the U.S. Los Alamos Nuclear Laboratory who gets regularly glimpses of the North's secretive nuclear program -- has set off alarm bells in Washington.

New Pictures Indicate North Korean Nuclear Construction -- Global Security Newswire


http://www.globalsecuritynewswire.org/gsn/nw_20101119_4988.php

Image released by the Institute for Science and International Security. UPI


Satellite photographs taken earlier this month indicate building work at North Korea's Yongbyon nuclear site, seemingly substantiating the aspiring nuclear power's earlier promise to construct a light-water reactor, the Associated Press reported today (see GSN, Nov. 19).

In March, Pyongyang pledged to erect a light-water reactor that would operate on its own atomic fuel. Two U.S. experts on North Korea came back from a trip to the isolated state this month and said new work at Yongbyon had started.

Alleged North Korean Reactor Flouts U.N., South Says


If North Korea is indeed constructing a light-water nuclear reactor, it would be in contravention to U.N. Security Council resolutions prohibiting the aspiring nuclear power from any nuclear work, South Korea's top diplomat said yesterday (see GSN, Nov. 15).
South Korean Foreign Minister Kim Sung-hwan said to journalists,"that would be running counter to U.N. resolutions and it is obvious that it wouldn't be conducive to the current situation," the Yonhap News Agency reported.
Siegfried Hecker, a former head of the Los Alamos National Laboratory in New Mexico, this week said the North was building the experimental reactor at its Yongbyon nuclear complex. Hecker was returning from a trip to the isolated state when he made the remarks.
Kim said additional time is required to probe Hecker's report as the Stalinist state has no background in constructing light-water reactors.
He also disputed Pyongyang's repeated assertion that it has the right to develop civilian atomic power, saying the North gave up that right when it withdrew from the Nuclear Nonproliferation Treaty in 2003 (Yonhap News Agency I, Nov. 15).
Responding to the light-water reactor report, the U.S. State Department yesterday again called on Pyongyang to demonstrate its commitment to denuclearization, Yonhap reported.
"We expect North Korea to live up to its international obligations," State Department spokesman P.J. Crowley said. "As it does, we are prepared to have conversations with North Korea about its long-term requirements. But first and foremost, North Korea has to live up to its stated commitment" (Hwang Doo-hyong, Yonhap News Agency II, Nov. 15).
The Obama administration has refused calls to return to the stalled six-nation talks -- which also involve China, Japan, the two Koreas, and Russia -- until Pyongyang shows it is sincere about nuclear disarmament. Washington fears a repeat performance from the North whereby Pyongyang takes some limited steps toward denuclearization only to reverse course once it has extracted some international concessions.
North Korea pulled out of nuclear negotiations in April 2009 and one month later detonated its second nuclear test device. That action earned it heightened U.N. Security Council sanctions that are thought to have left the already impoverished nation badly weakened.
Meanwhile, North Korea's state-controlled media yesterday announced former U.S. State Department official Morton Abramowitz had traveled to Pyongyang with a retinue of U.S. experts on North Korea. No further information was provided, Yonhap reported (Yonhap News Agency III, Nov. 15).

S.Korea voices concern at N.Korea nuclear report




http://www.spacewar.com/reports/SKorea_voices_concern_at_NKorea_nuclear_report_999.html Seoul (AFP) Nov 15, 2010 South Korea said Monday it could not confirm a report that North Korea is building a light-water nuclear reactor, but that any such move would run counter to disarmament hopes. A US scientist who travelled to the North last week said Saturday he had been told by officials there that work has started on such a reactor.
"They were saying that they are constructing a small experimental light-water reactor (at Yongbyon), eventually of the size of about 25 to 30 megawatts," Siegfried Hecker said in footage carried by Japanese public broadcaster NHK.
Light-water reactors are generally used for civilian nuclear purposes. Experts say it is relatively difficult to extract plutonium from them to make atomic weapons.
Some Seoul analysts say the North may be stressing its overall atomic expertise in hopes of prodding the United States into resuming stalled six-nation nuclear disarmament talks.
Foreign ministry spokesman Kim Young-Sun said the South has no information on its neighbour's capabilities in light-water reactors.
However, Kim said the project, if confirmed, "would be going contrary to expectations from members of the six-party talks and the international community."
The North promised to give up all nuclear weapons and nuclear-related programmes in a 2005 six-party agreement, Kim said.
"It is important for the North to sincerely carry out the promise and international obligations for peace and stability on the Korean peninsula."
The North quit the talks in April 2009 and staged its second nuclear test a month later.
In recent months it has expressed conditional willingness to resume talks, but in return it wants a lifting of sanctions and a US commitment to hold separate talks on a peace treaty.
The United States says the North must show willingness to denuclearise and mend ties with South Korea before the six-party talks can resume.
In 1994 the United States reached an agreement with the North Korea under which several countries were to build it two light-water reactors to generate electricity.
In return, the North was to shut down its plutonium-producing reactor at Yongbyon.
The deal broke down in 2002. The light-water reactors were never completed and the North restarted its original reactor.

North Korea Is Building Light - Water Reactor: Report

TOKYO (Reuters) - North Korea is building an experimental light-water reactor at its Yongbyon nuclear facility, Kyodo news reported on Saturday, citing Siegfried Hecker, former chief of the Los Alomos National Laboratory.
Hecker told reporters in Beijing that he was informed of the construction by North Korea and the output of the reactor was on a scale of 25 to 30 megawatts, according to the report.
Hecker recently visited North Korea, the report said.
He also said that the construction has just begun and it would take several years to complete it.
North Korea has tried to secure a light-water reactor for a number of years, claiming such a project would be for peaceful energy purposes.
The type of reactor is considered relatively proliferation-resistant, meaning it is unlikely to be diverted for an arms programme.
A 1994 deal between North Korea and the United States was intended to provide the destitute state with two 1,000-megawatt light-water reactors built by an international consortium, but the agreement fell apart in 2006 after the North was accused of pursuing a nuclear arms programme.
Analysts are skeptical of North Korea's ability to build a light-water reactor indigenously, because it requires key components that only advanced nuclear states such as the United States can provide.
North Korea froze its Yongbyon nuclear site under a 2005 deal with five regional powers in return for aid, but is reported to have restarted activities there recently as the six-way disarmament process remains stalled for two years.
A five-megawatt graphite-moderated reactor at Yongbyon has produced arms-grade plutonium that officials and experts believe the North used to build several nuclear bombs.
