John Kerry and Ernest Moniz: The case for the nuclear deal with Iran 2015-07-21T04:00:00Z The main benchmark by which analysts gauge Iran's ability to produce an atomic bomb is the "breakout" time — the time needed for Iran to produce enough weapons-grade enriched uranium for one nuclear bomb. The historic nuclear deal with Iran: How it works 2015-07-14T04:00:00Z Because of this deal, Iran will not produce the highly enriched uranium and weapons-grade plutonium that form the raw materials necessary for a nuclear bomb. Read President Obama's Remarks on Iran Nuclear Deal 2015-07-14T04:00:00Z February 2010 - Iran announces it has started to enrich uranium to near 20 percent, a technical step away from weapons-grade material. From covert Iran nuke program to final deal _ a timeline 2015-07-14T04:00:00Z Other agreements locked down or eliminated surplus inventories of weapons-grade uranium and plutonium to reduce the risk of nuclear terrorism. Future of nuclear arms control looks bleak, experts say 2015-07-09T04:00:00Z If Iran opts to return to enriching at levels just a technical step away from weapons-grade, it could have enough fissile material for one bomb within months. For world, limited options if Iran talks fall apart 2015-06-29T04:00:00Z The Obama administration argues that these limits would extend the time that Iran needs to enrich enough weapons-grade nuclear material for a bomb — called a “breakout time” — to a year.

Conflicting takes mean tough work ahead for Iran nuke deal 2015-04-15T04:00:00Z The accord would, for example, block Iran’s potential route to a plutonium bomb, by redesigning the country’s Arak heavy-water reactor to make it much less capable of producing weapons-grade plutonium. Close the deal 2015-04-13T04:00:00Z The Arak reactor would be redesigned and internationally certified to produce much less plutonium and no weapons-grade plutonium. A strong step toward a safer Iran 2015-04-12T04:00:00Z Both the United States and Iran agree that the Arak heavy-water reactor will be redesigned and rebuilt and will not produce weapons-grade plutonium. Differences Emerge in U.S., Iran Interpretations of Nuclear Deal 2015-04-09T04:00:00Z He says there's no risk of Iran amassing weapons-grade material because the stockpile is capped for a decade at 300 kilograms. Obama says Iran could cut nuke time to near zero in 13 years 2015-04-07T04:00:00Z “Moniz said this will not produce any weapons-grade plutonium,” said a senior American official, and that if the Iranians cheated it would be detectable right away. An Iran Nuclear Deal Built on Coffee, All-Nighters and Compromise 2015-04-03T04:00:00Z Much of its enriched stockpiles would be neutralized, and a planned reactor would be reconstructed so it can't produce weapons-grade plutonium.

Lawmakers Voice Skepticism on Iran Nuclear Deal 2014-07-29T04:00:00Z “Nothing is proliferation-proof in the nuclear field,” he said, but added that there were many technologies that were “proliferation resistant,” meaning they would not easily lead to weapons-grade fuel. Obama Likely to Seek Additional Time for Nuclear Negotiations With Iran 2014-07-16T04:00:00Z The U.S. believes that Iran could produce enough weapons-grade uranium to arm a single warhead in several months. Rep. Ed Royce pushes for new nuke sanctions on Iran 2014-07-15T04:00:00Z For some reason, professional, weapons-grade right-wing troll Ann Coulter doesn’t think her fellow Republicans should waste their time looking into issues of vote fraud. Ann Coulter’s voter fraud secret: Why she urged Republican not to push issue 2014-07-15T04:00:00Z From the ridge top, America’s most important storage facility for weapons-grade uranium no longer looked so intimidating. Nuns and Nuclear Security 2015-02-28T05:00:00Z But Ayatollah Khamenei, in describing Iran’s long-range needs, talked of a tenfold increase in enrichment capacity — so large that it would give Iran a “breakout time” of just weeks to produce weapons-grade fuel. Americans and Iranians See Constraints at Home in Nuclear Negotiations 2014-07-13T04:00:00Z That number could produce a bomb’s worth of weapons-grade material in just a few weeks, but Iran has nowhere near the ability to make that many centrifuges. Kerry to Join Talks on Iran as Deadline Draws Near 2014-07-10T04:00:00Z To the casual observer, a nuclear facility with weapons-grade uranium looks like a maximum-security prison, complete with armed guards and barbed wire.

Kerry Presses Iranians to Prove Nuclear Work Is for Peaceful Purposes 2014-01-25T02:24:27Z The higher the purity, the more dangerous – 90 percent is weapons-grade. Danger for Iran Deal 2014-01-15T16:05:29Z The country’s stockpile of uranium enriched to 20 percent, a step toward weapons-grade fuel, will be diluted or converted to oxide so that it cannot be readily prepared for military purposes. Negotiators Put Final Touches on Iran Accord 2014-01-13T02:02:54Z The six-month interim deal, which diplomats agreed on with Iran officials last month, temporarily stalls the nation from enriching uranium to produce weapons-grade material, the Associated Press . Obama's 50-50 Attitude About Iran Nuclear Deal 2013-12-07T23:05:19Z Acquiring the weapons-grade uranium was the hard part; detonating it was relatively easy. Nuns and Nuclear Security 2015-02-28T05:00:00Z AIPAC’s principal concern, shared by Israel and congressional opponents, is that the agreement allows Iran to continue low-level uranium enrichment that the group says could easily be ramped up to produce weapons-grade material. Obama, other administration officials reject criticism over interim Iran deal 2013-11-25T23:15:58Z That is because enrichment to a fissile concentration of 20 percent - compared to the 3.5 percent usually required for nuclear power plants - represents most of the work needed to reach weapons-grade uranium of 90 percent. Iran nuclear deal may reduce, not eliminate, any bomb breakout risk 2013-11-21T12:40:51Z Experts say Iran's 20%-enriched uranium could be enriched to weapons-grade, or 90%, in a relatively short time, while spent fuel from the Arak reactor will contain plutonium suitable for use in nuclear weapons.

Rift widens on Iranian nuclear deal as Israel, Arabs warn against allowing enrichment 2013-10-23T23:41:55Z At the core of the dispute are Iranian efforts to enrich uranium to 20 percent fissile purity, a technological advance that brings it close to producing weapons-grade fuel. Iran says 'too soon to judge' if progress made at Geneva nuclear talks 2013-10-15T18:00:03Z If the Iranians had an industrial-scale enrichment facility, with tens of thousands of centrifuge machines enriching low-enriched uranium, they could pretty quickly convert that facility to producing large quantities of weapons-grade uranium. What to Expect From the Iran Nuke Talks 2013-10-14T10:50:24Z But it has also amassed stocks of low-enriched uranium gas that experts say would be enough for several bombs if processed much further to weapons-grade material. Iran rejects West's demand to ship out uranium stockpiles 2013-10-13T19:18:07Z But let’s review the three stages to making a reliable nuclear weapon – weapons-grade material, weaponization, and delivery. Iran's Dangerous Nuclear Bluff 2013-10-13T08:27:00Z Uranium refined to 20 percent of fissile purity brings it technically close to the weapons-grade level of 90 percent. Israel bleak about U.S.-Iran rapprochement at U.N. summit 2013-09-24T18:50:25Z Experts estimate that enough uranium for one bomb would correspond to 25 kg of weapons-grade uranium, or roughly 250 kg enriched to 20 percent. Despite thaw, resolving Iranian nuclear dispute a huge challenge 2013-09-22T09:41:27Z This stock is closely watched in the West as it represents a short technical step from weapons-grade uranium. Iran adds to atom capacity, holds down stockpile growth: diplomats 2013-08-26T14:48:00Z “A more realistic estimate,” the study concluded, is that the doubling of capacity would enable North Korea to produce enough weapons-grade uranium per year for two nuclear weapons. Study Suggests North Korea Is Doubling Area Devoted to Uranium Enrichment 2013-08-08T08:59:16Z Obtaining weapons-grade fissile material - highly enriched uranium or plutonium - poses the biggest challenge for militant groups, so it must be kept secure both at civilian and military facilities, experts say. Governments warn about nuclear terrorism threat 2013-07-01T18:14:13Z Obtaining weapons-grade fissile material - highly enriched uranium or plutonium - poses the biggest challenge for militant groups, so keeping it secure is vital, both at civilian and military facilities, experts say.

Tank at Washington state nuclear site may be leaking radioactive waste 2013-06-21T22:40:17Z But it wasn't until Kamran Loghman worked with the FBI to develop a weapons-grade pepper spray that teargas really caught on as an everyday control agent. Teargas: a booming market in repressing dissent 2013-06-07T12:40:07Z Iran had refused at the talks in April in Almaty to stop enriching uranium to levels that close a significant technological gap en route to making weapons-grade material. EU's Ashton to meet Iran's nuclear negotiator on May 15 2013-05-02T19:59:13Z At the core of the powers' concerns is Iran's enrichment of uranium to 20 percent fissile purity, a level that closes an important technological gap en route to making weapons-grade material. World powers await Iran's reaction to nuclear offer 2013-04-04T22:13:24Z It announced Tuesday that it was reopening a reactor complex used to harvest weapons-grade plutonium. Seoul Seeks Ability to Make Nuclear Fuel 2013-04-03T00:57:09Z Experts who have visited the Yongbyon facility say the small reactor is ill suited for power production and geared instead to produce weapons-grade plutonium. U.S. struggling to contain nuclear threats from North Korea, Iran 2013-04-02T20:59:51Z Iran would need such an amount—if processed further into weapons-grade fuel—to produce one atomic bomb, experts believe. Iran Cools Nuclear Work as Vote Looms 2013-04-02T03:04:50Z The International Atomic Energy Agency reports regularly on Iran and has no evidence of uranium enrichment to weapons-grade level. Yesterday: Iraq. Tomorrow: Iran? 2013-03-18T15:13:32Z But the U.S. and its allies are concerned that 20-percent purity is a major step towards producing weapons-grade uranium and that Tehran is covertly developing weapons capability, accusations Iran denies. Iran's leader condemns West for not making nuclear concessions 2013-03-07T13:36:56Z Now it blends an overwhelming amount of data with a weapons-grade ability to nurture and an exquisite organizational acumen. Confidence Woman 2013-03-07T12:00:15Z But 20 percent purity is far higher than that needed for nuclear power, and rings alarm bells abroad because it is only a short technical step away from weapons-grade uranium. Iran sees chance to improve ties with U.S.: minister 2013-03-01T11:12:00Z But it also represents most of the work required to reach weapons-grade material of 90 percent.
