Abstract

APARATO PARA EL EXAMEN ULTRASONICO DE PERNOS DE FIJACION DE CUBIERTAS. LA INVENCION SE REFIERE A LA COMPROBACION ULTRASONICA DE LOS PERNOS DE FIJACION DEL SEPARADOR DE VAPOR DE UN REACTOR NUCLEAR DE AGUA HIRVIENDO (BWR). SE DESCRIBE UN APARATO PARA EL EXAMEN A DISTANCIA DE LOS PERNOS PERIFERICOS DE FIJACION DE CUBIERTA EN LOS SEPARADORES DE VAPOR EMPLEADOS EN LOS REACTORES BWR. LOS PERNOS DE FIJACION DE CUBIERTA RODEAN EL SEPARADOR DE VAPOR DE FORMA CILINDRICA EN LA CIRCUNFERENCIA EXTERNA Y SU LONGITUD ES LA MISMA QUE LA DEL SEPARADOR DE VAPOR, SIENDO DEL ORDEN DE 3,05 M. DURANTE LAS PARADAS DEL REACTOR, TODOS LOS PERNOS, CUYO NUMERO ESTA COMPRENDIDO ENTRE 24 Y 48, TIENEN LOS SALIENTES DE MANTENIMIENTO RECTANGULARES QUE ESTAN FORMADOS EN SU PARTE INFERIOR, ALINEADOS RADIALMENTE RESPECTO AL SEPARADOR DE VAPOR DE MODO QUE ESTEN ALEJADOS DE LOS SOPORTES CORRESPONDIENTES QUE ESTAN SITUADOS EN UNA CUBIERTASUPERPUESTA AL NUCLEO DE VAPOR.
