it particularly suitable for nuclear weapons use. Plutonium and uranium in grades normally used in nuclear weapons are the most common examples. (These...

reactor designs. The fissile uranium in nuclear weapon primaries usually contains 85% or more of 235U known as weapons grade, though theoretically for an...

Nuclear Weapons on 20 September 2017, and ratified it on 25 February 2019. As of 2015, South Africa still possessed most of the weapons grade uranium extracted...

knowledge. While uranium enriched to 77 percent is usually not considered weapons-grade, it could theoretically be used to construct a nuclear weapon. Highly enriched...

235U and is known as weapons grade uranium, though for a crude and inefficient weapon 20% enrichment is sufficient (called weapon(s)-usable). Even lower...

test site. It was a uranium-235 implosion fission device made from weapons-grade uranium (U-235) enriched in a gaseous diffusion plant in Lanzhou. The atomic...

highly enriched weapons-grade uranium-235, led to its use in nuclear weapons and nuclear power plants. The fissioning of an atom of uranium-235 in the reactor...

Uranium-238 (238U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile...

programs and costs billions of dollars. Weapon-grade uranium obtained from nuclear weapons is diluted with uranium-238 and reused as fuel for nuclear reactors...

much easier to develop in secret than existing weapons. Separating weapons-grade uranium (U-235) or breeding plutonium (Pu-239) requires a substantial and...

weapons material, though it was only superior to plutonium in rare circumstances. It was claimed that if the existing weapons were based on uranium-233...

Further processing can yield weapons-grade uranium with U-235 levels usually above 90%, suitable for nuclear weapons. The uranium in yellowcake is almost exclusively...

Pakistan is one of nine states that possess nuclear weapons. Pakistan began developing nuclear weapons in January 1972 under Prime Minister Zulfikar Ali...

Reactor-grade plutonium (RGPu) is the isotopic grade of plutonium that is found in spent nuclear fuel after the uranium-235 primary fuel that a nuclear...

Korea has a military nuclear weapons program and, as of 2024, is estimated to have an arsenal of approximately 50 nuclear weapons and sufficient production...

Gun-type fission weapons are fission-based nuclear weapons whose design assembles their fissile material into a supercritical mass by the use of the "gun"...
