With concerns rising over Iran's reported 400 kilograms of uranium, experts analyze how much nuclear weapon-grade material ...

A byproduct of the process is uranium-238, which can be processed into plutonium-239. This is a more fissile product than uranium and can make lighter-weight weapons.

The stockpile of uranium enriched to 60 per cent – part of an overall stockpile of more than 8,400kg, the majority of it low-level purity – meant Tehran had the capacity to produce sufficient fissile ...

ON bombarding uranium with neutrons, Fermi and collaborators1 found that at least four radioactive substances were produced, to two of which atomic numbers larger than 92 were ascribed. Further ...

It either must be enriched—made more concentrated in a rare form of uranium (U-235)—or converted into plutonium (Pu-239). Heavy water can play a role in breeding weapons-grade plutonium from ...

The uranium enrichment impasse threatens to collapse diplomatic efforts. As Iran continues advancing its nuclear capabilities, the timeline for Tehran to potentially develop a nuclear weapon shortens.

Uranium discovered in Chimney Hollow Dam, the largest built in United States in 20 years 03:41. Just weeks before completion of construction, Northern Water has confirmed uranium has been ...
