North Korea ramps up uranium enrichment, enough for six nuclear bombs a year: experts

SEOUL (Reuters) – North Korea will have enough material for about 20 nuclear bombs by the end of this year, with ramped-up uranium enrichment facilities and an existing stockpile of plutonium, according to new assessments by weapons experts.

The North has evaded a decade of U.N. sanctions to develop the uranium enrichment process, enabling it to run an effectively self-sufficient nuclear program that is capable of producing around six nuclear bombs a year, they said.

The true nuclear capability of the isolated and secretive state is impossible to verify. But after Pyongyang conducted its fifth and most powerful nuclear test last week and, according to South Korea, was preparing for another, it appears to have no shortage of material to test with.

North Korea has an abundance of uranium reserves and has been working covertly for well over a decade on a project to enrich the material to weapons-grade level, the experts say.

That project, believed to have been expanded significantly, is likely the source of up to 150 kilograms (330 pounds) of highly enriched uranium a year, said Siegfried Hecker, a leading expert on the North’s nuclear program.

That quantity is enough for roughly six nuclear bombs, Hecker, who toured the North’s main Yongbyon nuclear facility in 2010, wrote in a report on the 38 North website of Johns Hopkins University in Washington published on Monday.

Added to an estimated 32- to 54 kilogram plutonium stockpile, the North will have sufficient fissile material for about 20 bombs by the end of 2016, Hecker said.

North Korea said its latest test proved it was capable of mounting a nuclear warhead on a medium-range ballistic missile, but its claims to be able to miniaturize a nuclear device have never been independently verified. [nL3N1BL1ND]

Assessments of the North’s plutonium stockpile are generally consistent and believed to be accurate because experts and governments can estimate plutonium production levels from telltale signs of reactor operation in satellite imagery.

South Korean Defence Minister Han Min-koo this year estimated the North’s plutonium stockpile at about 40 kilograms.

But Hecker, a former director of the U.S. Los Alamos National Laboratory, where nuclear weapons have been designed, has called North Korea’s uranium enrichment program “their new nuclear wildcard,” because Western experts do not know how advanced it is.

PAKISTAN CONNECTION

Jeffrey Lewis of the California-based Middlebury Institute of International Studies said North Korea had an unconstrained source of fissile material, both plutonium from the Yongbyon reactor and highly-enriched uranium from at least one and probably two sites.

“The primary constraint on its program is gone,” Lewis said. Weapons-grade plutonium has to be extracted from spent fuel taken out of reactors and then reprocessed, and therefore would be limited in quantity. A uranium enrichment program greatly boosts production of material for weapons.

The known history of the uranium enrichment project dates to 2003, when the North was confronted by the United States with evidence of a clandestine program to build a facility to enrich uranium with the help of Pakistan.

Former Pakistani President Pervez Musharraf said in his memoirs that A.Q. Khan, the father of that country’s nuclear program, transferred two dozen centrifuges to the North and some technical expertise around 1999.

“It was also clear that the suspected Pakistani connection had taken place, as the centrifuge design resembled Pakistan’s P-2 centrifuge,” Hecker said in a report in May.

Hecker reported being shown around a two-story building in the Yongbyon complex in November 2010 that a North Korean engineer said contained 2,000 centrifuges and a control room Hecker called “astonishingly modern.”

By 2009, the North had likely acquired the technology to be able to expand the uranium project indigenously, Joshua Pollack, editor of the U.S.-based Nonproliferation Review, has said.

North Korea has not explicitly admitted to operating the centrifuges to produce weapons-enriched uranium, instead claiming they were intended to generate fuel for a light water reactor it was going to build.

Despite sanctions, by now North Korea is probably largely self-sufficient in operating its nuclear program, although it may still struggle to produce some material and items, Lewis said.

“While we saw this work in Iran, over time countries can adjust to sanctions,” he said.

North Korea says it has resumed plutonium production: Kyodo

TOKYO (Reuters) – North Korea says it has resumed plutonium production by reprocessing spent fuel rods and has no plans to stop nuclear tests as long as perceived U.S. threats remain, Japan’s Kyodo news agency reported on Wednesday.

North Korea’s Atomic Energy Institute, which has jurisdiction over its main Yongbyon nuclear facilities, also told Kyodo it had been producing highly enriched uranium necessary for nuclear arms and power “as scheduled”.

“We have reprocessed spent nuclear fuel rods removed from a graphite-moderated reactor,” the institute told Kyodo in a written interview.

The institute did not mention the amount of plutonium or enriched uranium it had produced, Kyodo said.

The U.N. nuclear watchdog, the International Atomic Energy Agency (IAEA), said in June North Korea appeared to have reopened the Yongbyon plant to produce plutonium from spent fuel of a reactor central to its atomic weapons drive.

North Korea vowed in 2013 to restart all nuclear facilities, including the main reactor at its Yongbyon site that had been shut down.

North Korea had said in September that Yongbyon was operating and that it was working to improve the “quality and quantity” of its nuclear weapons.

North Korea conducted its fourth nuclear test in January.

According to Kyodo, the North Korean institute said it had already succeeded in making “lighter and diversifying” nuclear weapons, and that it had no intention of halting nuclear tests.

“Under conditions that the United States constantly threatens us with nuclear weapons, we will not discontinue nuclear tests,” the institute was quoted by Kyodo as saying.

North Korea will also build a 100,000-kilowatt light-water nuclear reactor for experimental use, the institute was quoted as saying, but it did not provide further details.

Little is known about the quantities of weapons-grade uranium or plutonium that North Korea possesses, or its ability to produce either, though plutonium from spent fuel at Yongbyon is widely believed to have been used in its nuclear bombs.

North Korea has come under tightening international pressure over its nuclear weapons program, including tougher U.N. sanctions adopted in March backed by its lone major ally China.

China Testing ICBM With Multiple Warheads

China has carried out a test of a long range missile that is capable of delivering multiple independent nuclear warheads.

The test of the DF-41 missile marks the longest range intercontinental ballistic missile in China’s arsenal.  It’s also the first missile in China’s fleet that is capable of delivering multiple warheads.

The development means that China will likely have a rapid, significant increase in the total number of large warheads available for missile launch.  The defense department estimates that China currently has around 240 very large warheads.

China had announced the likely power of the DF-41 in a report earlier this month.

“The DF-41, which could be deployed as early as 2015, may carry up to 10 MIRVs, and have a maximum range as far as 7,456 miles, allowing it to target the entire continental United States,” the report said. “In addition, some sources claim China has modified the DF–5 and the DF–31A to be able to carry MIRVs.”

Defense department officials say that China’s new missile would require the United States to upgrade its current ballistic missile defense systems.

Iranian Official Admits Country Sought Nuclear Weapons

In the first official confirmation of what’s always been assumed, an Iranian official has admitted his country was attempting to get their hands on nuclear weapons.

General Mohsen Rafiqdoost, a founder of Iran’s Revolutionary Guards, told an Iranian news outlet on Saturday that they had pursued ways to gain nuclear arms.  He said that when he approached Ayatollah Ruhollah Khomeini about the project, he said the Imam told him “do not pursue atoms” and he stopped the plan.

However, a letter that was shown from the 1980s showed that Khomeini had later approved of seeking the weapons.

Gen. Rafiqdoost was the first minister of the Revolutionary Guard and was tasked with obtaining weapons for the country on the black market.

Iran is refusing to dismantle centrifuges that could produce material for nuclear weapons claiming it is not part of the recently implemented temporary deal with western world powers.

Nuclear Missile Officers In Cheating Scandal

The men who have their fingers on the button have been cheating to keep them there.

Thirty-four nuclear missile launch officers have been stripped of their certification and duty after it was discovered they had been cheating on monthly required tests to maintain their positions.  The cheating was discovered during an unrelated investigation into drug use among Air Force officers.

Air Force Secretary Deborah Lee James told reporters Wednesday that the officers were texting each other answers.  The tests were monthly exams on the operation of the missile systems.  In addition to the officers who actually cheated, any officer aware of the cheating who did not report the situation to superior officers were also removed from duty.

Three of the officers involved in the cheating scandal were also arrested as part of a drug sting that covered six bases in the U.S. and England.

The missile command system covers 450 nuclear missiles.
