Article · Deutsch
Uran (benannt nach dem Planeten Uranus) ist ein chemisches Element mit dem Elementsymbol U und der Ordnungszahl 92. Im Periodensystem steht es in der Gruppe der Actinoide (7. Periode, f-Block). Uran ist ein Metall, dessen sämtliche Isotope radioaktiv sind. Natürlich in Mineralen auftretendes Uran besteht zu etwa 99,3 % aus dem Isotop 238U und zu 0,7 % aus 235U. Eine besondere Bedeutung erhielt Uran nach der Entdeckung der Kernspaltung im Jahre 1938. Das Uranisotop 235U ist durch thermische Neutronen spaltbar und damit – neben dem äußerst seltenen, aber aus Uran erzeugbaren Plutonium-Isotop 239Pu – das einzige natürlich vorkommende Nuklid, mit dem eine selbsterhaltende Kernspaltungs-Kettenreaktion möglich ist. Daher findet es Verwendung als Primärenergieträger in Kernkraftwerken und Kernwaffen.
