What is uranium enrichment? Enrichment is a process that increases the capacity of uranium to fuel a nuclear chain reaction, either for use in nuclear power plants or for nuclear weapons. Uranium primarily occurs naturally as two isotopes : 99. 3% is uranium-238 and 0. 7% is uranium-235. Their atoms are identical except for the number of neutrons in the nucleus : uranium-238 has three more and this makes it less able to fission. Uranium enrichment is used to increase the percentage of the fissile U-235. 2, record 2, English, - uranium%20enrichment

El enriquecimiento de uranio es el proceso al cual es sometido el uranio natural para obtener el isótopo 235U conocido como uranio enriquecido. El uranio natural se compone principalmente del isótopo 238U, con una proporción en peso de alrededor del 0,7 % de 235U, el único isótopo en cantidad apreciable existente en la naturaleza que es fisionable mediante neutrones térmicos. Durante el enriquecimiento, el contenido porcentual de 235U en el uranio natural se incrementa gracias al proceso de separación de isótopos. 1, record 2, Spanish, - enriquecimiento%20de%20uranio

Dans un combustible pour réacteur à eau légère la matière fissile se présente sous forme de petits cylindres en oxyde d'uranium fritté dits «pastilles». Un certain nombre de ces pastilles est empilé dans un tube - dit tube de gainage ou gaine - scellé aux deux extrémités par des bouchons soudés afin d'isoler la matière fissile du milieu extérieur; cet ensemble forme ce qu'on appelle un crayon combustible. 1, record 13, French, - tube%20de%20gainage

In the seventies, the CEA, in collaboration with its subsidiaries Sfec and Technicatome, developed a fuel with a low level of enrichment, Caramel. The CEA used complete cores of Caramel in the Isis and Osiris reactors. It recently abandoned use of Caramel in Osiris to the benefit of silicide fuel. Caramel fuel was and, it seems, may still be, used in submarines. Caramel fuel is composed of flat pastilles of uranium oxide enriched to about 7. 5%. Each pastille has almost the shape and size of a true caramel, hence the name. 1, record 14, English, - Caramel%20fuel
