Separation of tritium from hydrogen by thermal diffusion
- 1. Los Alamos Scientific Laboratory of The University of California, Los Alamos, NM (United States)
Description
In many applications of tritium, a high degree of isotopic purity is necessary. The tritium obtained from neutron irradiation of lithium has associated with it varying amounts of hydrogen. Because of the large ratio of the masses of hydrogen and tritium, almost any separation system will give a large enrichment. In this paper, details are given of a thermal diffusion column to produce large amounts of 99.8% T2, routinely. Special handling techniques have been developed to pump, monitor and analyse the process gases without exposing the operating personnel to dangerous amounts of radiation. The He3 was periodically stripped from the tritium by differential adsorption on charcoal at liquid-nitrogen temperatures. Care M'as taken quantitatively to save this material because of its scientific value. (author)
Abstract (French)
Pour de nombreuses applications du tritium, un degre eleve de purete isotopique est necessaire. Le tritium obtenu par irradiation neutronique du lithium est associe a des quantites d'hydrogene variables. En raison du rapport important entre les masses d'hydrogene et de tritium, presque tous les procedes de separation donneront un enrichissement eleve. Les auteurs decrivent en detail une colonne de diffusion thermique permettant' de produire couramment de grandes quantites de T2 a 99,8% de purete. Des techniques de manipulation speciale ont ete mises au point pour pomper, controler et analyser les gaz traites sans exposer le personnel a des quantites de rayonnements dangereux. Le 3He a ete separe periodiquement du tritium par adsorption differentielle sur du charbon a des temperatures egales a celles de l'azote liquide. On s'est efforce de recuperer la totalite de ce produit en raison de sa valeur scientifique. (author)Abstract (Spanish)
En muchas de las aplicaciones del tritio se requiere una sustancia de elevada pureza isotopica. El tritio que se obtiene por bombardeo del litio con neutrones contiene cantidades variables de hidrogeno. Como la razon de la masa del tritio a la del hidrogeno es muy elevada, casi todos los metodos de separacion permiten alcanzar un alto grado de enriquecimiento. Los autores dan detalles de una columna de difusion termica con la que se obtienen regularmente grandes cantidades de T2 de 99,8 por ciento de pureza. Se idearon metodos especiales para el bombeo, monitoraje y analisis de los gases sin exponer al personal, a dosis peligrosas de radiaciones. El 3He se separaba periodicamente del tritio por adsorcion diferencial en carbon de lena a la temperatura del nitrogeno liquido. Debido a su valor desde el punto de vista cientifico, se adoptaron precauciones para lograr la recuperacion cuantitativa de esta sustancia. (author)Abstract (Russian)
Vo mnogikh sluchayakh primeneniya tritiya trebuetsya vysokaya stepen' izotopnoj chistoty. Tritij, poluchaemyj nejtronnym oblucheniem litiya, zakhvatyvaet s soboj razlichnye kolichestva vodoroda. Vvidu bol'shogo sootnosheniya mezhdu massami vodoroda i tritiya, kotoroe yavlyaetsya naivysshim vozmozhnym dlya izotopov, pochti vsyakaya sistema razdeleniya dast bol'shoe obogashchenie. Privodyatsya podrobnye dannye o kolonne teplovoj diffuzii dlya proizvodstvennoj vyrabotki bol'shikh kolichestv 99,8-protsentnogo T2. Byli vyrabotany osobye metody vykachivaniya, dozimetricheskogo kontrolya i analiza proizvodimykh gazov bez togo, chtoby podvergat' obsluzhivayushchij personal opasnomu kolichestvu radiatsii. He3 periodicheski otryvalsya ot tritiya posredstvom differentsial'nogo pogloshcheniya drevesnym uglem pri temperature zhidkogo azota. Vvidu bol'shoj tsennosti ehtogo materiala prinimalis' tshchatel'nye mery predostorozhnosti dlya ehkonomii ehtogo materiala. (author)Additional details
