Abstract

EN UN REACTOR DE AGUA HIRVIENTE, UN APARATO Y UN PROCEDIMIENTO PARA INSPECCION ULTRASONICA DE LA GUIA SUPERIOR SON DESCRITOS A CONTINUACION. LA GUIA SUPERIOR CONSTITUYE UNA REJILLA DE BARRAS DE ACERO INOXIDABLE QUE SE ENCUENTRAN SOBRE LA PLACA DE NUCLEO Y QUE SON MONTADAS EN RANURAS ENFRENTADAS CON LA REJILLA MONTADA EN LOS BORDES LATERALES EN EL RECIPIENTE DE PRESION DEL REACTOR. ESTA REJILLA APUNTALA LOS EXTREMOS SUPERIORES DE LOS CONJUNTOS DE COMBUSTIBLE APOYADOS VERTICALMENTE EN SU ORIENTACION REQUERIDA Y ESPCAIADOS PARA PERMITIR, ENTRE OTRAS COSAS, QUE EL INTERVALO ESPACIAL REQUERIDO SEA MANTENIDO PARA MODERACION DE LA REACCION POR BARRA DE CONTROL. DEBIDO A LA PROXIMIDAD DE LA GUIA SUPERIOR A LOS CONJUNTOS DE COMBUSTIBLE, LAS BARRAS INDIVIDUALES QUE CONSTITUYEN LA REJILLA REQUIEREN SER VERIFICADAS EN CUANTO A GRIETAS, ESPECIALMENTE LAS GRIETAS PRODUCIDAS POR CORROSION DE GRIETA POR TENSION FAVORECIDA POR IRRADIACION. CON UNA CELDA DEFINIDA EN LA REJILLA VACIADA DE SUS CONJUNTOS DE COMBUSTIBLE CONTENIDO Y ADYACENTES, SE DESCRIBE UNA VERIFICACION ULTRASONICA DE GRIETAS. UN TRANSDUCTOR DE SONIDO EN UN PRIMER BASTIDOR ESPECIAL BARRE HORIZONTALMENTE A TRAVES DE LA PARTE SUPERIOR DE UNA BARRA INTERROGANDOLA CON ONDAS ULTRASONICAS VERTICALES PARA DETECTAR GRIETAS HORIZONTALES. ANALOGAMENTE, UN TRANSDUCTOR DE SONIDO EN UN SEGUNDO BASTIDOR ESPECIAL BARRE VERTICALMENTE EL LADO DE UNA BARRA INTERROGANDOLA CON ONDAS ULTRASONICAS HORIZONTALES QUE INCIDEN ANGULARMENTE PARA DETECTAR GRIETAS VERTICALES. SE PRODUCE LA VERIFICACION NO DESTRUCTIVA DEL CONJUNTO DE REJILLA SIN QUE SE REQUIERA EL DESMONTAJE.
