Om even nog verder te gaan :
http://en.wikipedia.org/wiki/Enriched_uraniumquote:
Enriched uranium is a kind of uranium in which the percent composition of uranium-235 has been increased through the process of isotope separation. Natural uranium (or NU) is 99.284% 238U isotope, with 235U only constituting about 0.711% of its weight. However, 235U is the only isotope existing in nature (in any appreciable amount) that is fissionable by thermal neutrons.
Enriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons.

The following countries are known to operate enrichment facilities: Argentina, Brazil, China, France, Germany, India, Japan, the Netherlands, Pakistan, Russia, the United Kingdom and the United States. Israel and North Korea are also suspected of having enrichment programs.
