The United States and other Western nations have demanded that Iran stopped its uranium-enrichment program, which they perceive as a precursor to production of nuclear warhead-grade material.
Unfortunately for Kodak, not even weapons-grade nuclear power could save the company from its own irrelevance in the digital age.
The U.S. and its allies are seeking to gain Iran's willingness to suspend its production of near weapons-grade nuclear material at its uranium-enrichment sites in return for economic incentives.
WSJ: Iran Says It Is Set for Nuclear Talks, but West Is Skeptical
In 1994, North Korea agreed to stop making plutonium, in return for which America and its allies would supply the country with fuel oil and build two Western-designed light-water nuclear reactors (since it is a bit harder to produce weapons-grade materials from such reactors than from the ones North Korea had been building).
It is building a facility in South Carolina to transform excess weapons-grade plutonium into fuel for nuclear reactors.
That, Mr Netanyahu said, represented the point when Iran would have sufficient 20%-enriched uranium to produce enough of the weapons-grade variety needed for a nuclear warhead.
What if we could build a nuclear reactor that offered no possibility of a meltdown, generated its power inexpensively, created no weapons-grade by-products, and burnt up existing high-level waste as well as old nuclear weapon stockpiles?
FORBES: Is Thorium the Biggest Energy Breakthrough Since Fire? Possibly.
Experts including Duelfer and Anthony Cordesman, a military analyst at the Center for Strategic and International Studies in Washington, believe Saddam has the sophisticated triggers, weapon housings and everything else he needs to build a nuclear device--except for a sufficient supply of weapons-grade enriched uranium.
Russia and America finalised a decade-old deal to eliminate 68 tonnes of weapons-grade plutonium, enough for nearly 17, 000 nuclear devices.
Nuclear weapons, too, can be produced using either uranium enriched to weapons-grade or plutonium.
One reason why many people distrust nuclear power is because they believe it is impossible to separate civil reactors from weapons-grade fissile material.
As part of my job, I reported alarming inadequacies: in one case high-grade equipment (ASME III, class 1) was operated in nuclear power reactors with no accepted safety file, regardless of a previous accident and a half-dozen failures in achieving acceptable design results.
That reactor type is not ideal for producing weapons-grade plutonium, but all reactors produce plutonium that could be used in a nuclear explosion.
For uranium to work in a nuclear reactor it must be enriched to contain 2-3% uranium-235 while weapons-grade uranium must contain 90% or more uranium-235.
The MOX facility will blend surplus weapon-grade plutonium with depleted uranium oxide to make mixed oxide fuel for use in existing nuclear power plants.
