Nuclear weapons can win a war decisively and ... It must be processed through high-performance centrifuges into uranium-235, which is more fissile. A byproduct of the process is uranium-238 ...

Naturally occurring uranium contains only about 0.7 percent U-235. Most of the remainder is the isotope U-238. To be used in a nuclear power plant, uranium must be enriched to contain more U-235.

The facility will use centrifuges to produce low-enriched fuel composed up to 8% of the powerful uranium-235 isotope ... licensing process with the U.S. Nuclear Regulatory Commission, which ...

The enrichment centrifuge is a device used to extract uranium-235 isotope from a sample of natural uranium. U-235 is fissile and thus useful to generate nuclear power and to build nuclear weapons.

Uranium 235 concentrations are below one percent ... which can reach over 90 percent enrichment for uses like nuclear weapons. “Historically, 20 percent has been considered a threshold ...
