Abstract

EN UN SISTEMA DE IDENTIFICACION DE BARRAS DE COMBUSTIBLE NUCLEAR, SE PROPORCIONAN SEÑALES SOBRE LAS BARRAS DE COMBUSTIBLE NUCLEAR EN DOS ETAPAS. EN LA PRIMERA ETAPA, MEDIANTE EL USO DE UN RAYO LASER, SE APLICA DIRECTAMENTE UN CODIGO DE BARRAS AL TUBO DE RECUBRIMIENTO DE LAS BARRAS DE COMBUSTIBLE ANTES DE CARGARLAS CON COMBUSTIBLE NUCLEAR Y SE FIJAN UNAS ESPITAS EN LOS EXTREMOS OPUESTOS DE ESTAS PARA PROPORCIONAR UNA BARRA DE COMBUSTIBLE ENSAMBLADA. EN LA SEGUNDA ETAPA, DESPUES DE CARGAR EL COMBUSTIBLE NUCLEAR Y FIJAR LAS ESPITAS EN LOS EXTREMOS OPUESTOS DEL TUBO DE REVESTIMIENTO DE LA BARRA DE COMBUSTIBLE CON EL CODIGO DE BARRAS APLICADO PARA PROPORCIONAR UNA BARRA DE COMBUSTIBLE ENSAMBLADA, MEDIANTE EL USO DE UN RAYO LASER, SE APLICAN SIMBOLOGIAS DE ENRIQUECIMIENTO E IDENTIFICACION RESPECTIVAMENTE AL EXTREMO LATERAL DE UNA DE LAS ESPITAS DE LA BARRA DE COMBUSTIBLE ENSAMBLADA.
