Abstract

APARATO Y METODO PARA MEDIR EL ESPESOR DE UNA CAPA-BARRERA SOBRE LA SUPERFICIE INTERIOR DE UN TUBO CILINDRICO DE COMBUSTIBLE NUCLEAR. UN APARATO QUE UTILIZA FLUORESCENCIA DE RAYOS X PARA MEDIR EL ESPESOR DE UNA CAPA-BARRERA DE ZIRCONIO EN LA SUPERFICIE INTERIOR DE UN TUBO DE COMBUSTIBLE NUCLEAR DE ALEACION DE ZIRCONIO ES DESCRITO EN LA INVENCION. UNA FUENTE DE RADIACION GAMMA COLOCADA COAXIALMENTE EN EL TUBO EMITE RAYOS GAMMA LOS CUALES EXCITAN RAYOS X K-ALFA Y B-BETA SN EN EL SUSTRATO DE ALEACION DE ZIRCONIO. LOS RAYOS X FLUORESCENTES QUE PASAN DE RETORNO A TRAVES DE CAPA-BARRA SON DETECTADOS POR UN DETECTOR DE RAYOS X COLOCADO EN EL TUBO. LA ATENUACION DE LOS RAYOS GAMMA DE EXCITACION Y LOS RAYOS X FLUORESCENTES POR LA CAPA-BARRERA ES UTILIZADA PARA DETERMINAR EL ESPESOR DE CAPA-BARRERA.
