Abstract

CILINDRO DE CONTROL PARA REACTOR NUCLEAR QUE TIENE UNA CONFIGURACION CRUCIFORME CON CUATRO ELEMENTOS PLANOS (S4), DOTADO DE UNA MEMBRANA (70) CONTRA LAS FISURAS Y LA CORROSION. CADA UNO DE LOS CUATRO ELEMENTOS PLANOS (S4) DEL CILINDRO DE CONTROL ESTA FABRICADO MEDIANTE EL SOLDEO LADO A LADO DE ELEMENTOS TUBULARES (O A PARTIR DE PLACAS PLANAS PERFORADAS LONGITUDINALMENTE) QUE CONTIENEN VENENOS NUCLEARES SELLADOS ABSORBENTES DE NEUTRONES. LA MEMBRANA DE PROTECCION (70) ESTA ENVUELTA EN TORNO A CADA ELEMENTO ESTRUCTURAL PLANO. LA MEMBRANA DE PROTECCION RODEA AL ELEMENTO Y NO ESTA BAJO TENSION, SIENDO MANTENIDO PREFERENTEMENTE EL ELEMENTO PLANO BAJO COMPRESION POR LA PRESION AMBIENTAL DEL REACTOR. LA MEMBRANA PROPORCIONA UN MARGEN ADICIONAL CONTRA LAS FISURAS Y LA CORROSION EVITANDO QUE EL AGUA DEL REACTOR SE PONGA EN CONTACTO CON LOS ELEMENTOS TUBULARES SOLDADOS DE LADO A LADO (O PLACAS PERFORADAS). CUANDO LA MEMBRANA NO ESTA BAJO TENSION, ESTA NO SE HALLA SUJETA A LOS ESFUERZOS PRODUCIDOS POR LA IRRADIACION QUE PROVOCAN LA FISURA Y CORROSION NI A LOS ESFUERZOS CONVENCIONALES DE FISURA Y CORROSION.
