Uranium 238

Uranium 238. In its natural state common uranium (U238) can’t generate destructive nuclear explosions It either must be enriched—made more concentrated in.

Enriched uranium is a type of uranium in which the percent composition of uranium235 (written 235 U) has been increased through the process of isotope separationNaturally occurring uranium is composed of three major isotopes uranium238 (238 U with 992739–992752% natural abundance) uranium235 (235 U 07198–07202%) and uranium234 (234 U 00050–00059%).

Enrichment requires uranium to be in a gaseous form and the simplest way to achieve this is to convert it to a different chemical known as uranium hexafluorideUranium needs to be in a gaseous form for enrichment due to the varying chemical and physical properties the different isotopes (U235 and U238) have.

Isotopes of uranium Wikipedia

Uranium238 has a halflife of an incredible 45 billion years Uranium235 has a halflife of just over 700 million years Uranium234 has the shortest halflife of them all at 245500 years but.

Uranium is a common naturally occurring and radioactive substance It is a normal part of rocks soil air and water and it occurs in nature in the form of minerals – but never as a metal Uranium metal is silvercolored with a gray surface and is nearly as strong as steelNatural uranium is a mixture of three types or isotopes called U234/234U U235/235U and U238/238U.
