Made between two conditions: (i) one where chemical equilibrium is established and (ii) one where chemical equilibrium is not reached within the time frame considered. If equilibrium can be established, the fractionation is of thermodynamic origin and its extent is governed by the difference in vibrational energy levels of both reagent and reaction product as a function of isotope mass. DG values differ depending on whether the light or the heavy isotope is present and this affects the equilibrium constant, as: DG K ¼ eÀRT where R is the universal gas constant and T the prevailing temperature.

Evidence of fission in U deposits with much higher grades than Oklo but having ages about 300–400 million years younger has been sought, but was never found. For energy production in a light-water nuclear plant or for nuclear weapons, the fraction of 235U in natural uranium is too low. Therefore, several approaches have been developed to increase the relative abundance of this isotope. For the production of the first atomic bomb at Oak Ridge, TN (USA), 235U and 238U were separated from one another by “preparative” mass spectrometry using large magnetic sectors (calutrons) after conversion to UCl4 and electron ionization [62].
