યુરેનિયમ: આવૃત્તિઓ વચ્ચેનો તફાવત

While uranium-238 has a small probability for [[spontaneous fission]] or even induced fission with fast neutrons, uranium-235 and to a lesser degree uranium-233 have a much higher fission cross-section for slow neutrons. In sufficient concentration, these isotopes maintain a sustained [[nuclear chain reaction]]. This generates the heat in nuclear power reactors, and produces the fissile material for [[nuclear weapon]]s. [[Depleted uranium]] (²³⁸U) is used in [[kinetic energy penetrator]]s and [[vehicle armour|armor plating]].<ref name="BuildingBlocks479">{{Harvnb|Emsley|2001|p=479}}.</ref>
