Abstract

LA INVENCION SUMINISTRA UN PROCESO PARA LA OXIDACION DE HEXAFLUORURO DE URANIO INYECTANDO HEXAFLUORURO DE URANIO Y UN GAS OXIDANTE JUNTOS EN EL INTERIOR DE UN VASO DE REACCION PARA FORMAR UNA PLUMA QUE SE CARACTERIZA EN QUE UNA PLURALIDAD DE LAS PLUMAS SE FORMAN JUNTAS EN EL MISMO VASO, LAS PLUMAS CONTRIBUYEN MUTUAMENTE A LA FORMACION DE UNA CORRIENTE DE PRODUCTO CIRCULANTE EN EL VASO. EL PROCESO PUEDE INCLUIR EL ESTABLECIMIENTO DE TRES O MAS PLUMAS SIMULTANEAMENTE QUE CONTRIBUYEN A LA REACCION ENTRE LOS GASES EN EL VASO DE REACCION. EL GAS OXIDANTE PUEDE COMPRENDER VAPOR. EL PROCESO PUEDE SER UNO EN EL CUAL EL PRODUCTO SEA FORMADO EN FORMA DE PARTICULAS SOLIDAS. LAS PARTICULAS DEL PRODUCTO PUEDEN FORMARSE INICIALMENTE COMO PARTICULAS DENDRITICAS QUE PUEDEN HACERSE RECIRCULAR EN EL VASO DE REACCION PARA PROMOVER EL GERMEN, EL CRECIMIENTO, LA AGLOMERACION Y LA CONGREGACION DE LAS PARTICULAS DE PRODUCTOS REQUERIDAS, LAS PLUMAS CONTRIBUYEN DE ESTA FORMA AL PROCESO DE FORMACION DEL PRODUCTO ENEL VASO.
