Abstract
SE PRESENTA UN APARATO Y PROCESO PARA EL MONTAJE Y CONSTRUCCION DE UNA BARRA DE CONTROL EN UN REACTOR NUCLEAR EN EL QUE LA BARRA DE CONTROL (FIG. 2A) TIENE UNA CONFIGURACION CRUCIFORME CON UN CONJUNTO DE, PREFERIBLEMENTE CUATRO, ELEMENTOS PLANOS COPLANARES (S) CADA UNO HECHO CON UN MONTAJE DE ELEMENTOS TUBULARES DE SECCION TRANSVERSAL CUADRADA (T). CADA ELEMENTO TUBULAR DE SECCION CUADRADA INCLUYE UN ELEMENTO CENTRAL CILINDRICO DEFINIDO (40) Y UNA CARCASA METALICA TUBULAR QUE LO RODEA (30) DE UN ESPESOR CONSTANTE (36) DEFINIENDO UNA VASIJA DE PRESION CONFORMADA CILINDRICAMENTE PARA CONTENER LOS MATERIALES ABSORBIENDO NEUTRONES. LA CARCASA TUBULAR DE ESPESOR CONSTANTE QUE LO RODEA TIENE CUATRO SECCIONES EN LAS ESQUINAS (31, 34) QUE SE AÑADEN PARA GENERAR UN PERFIL EXTERIOR CUADRADO MODIFICADO CON UN ESPESOR ADICIONAL EN LAS ESQUINAS. LOS ELEMENTOS TUBULARES DE SECCION TRANSVERSAL CUADRADA SON SOLDADOS JUNTOS PARA EXTENDER AXIAL Y LONGITUDINALMENTE LA LONGITUD DE LA BARRA DE CONTROL EN LADIRECCION DEL MOVIMIENTO DE LA BARRA DE CONTROL Y DEL FLUJO DE FLUIDO. LOS ELEMENTOS TUBULARES DE SECCION TRANSVERSAL CUADRADA (T) SE LLENAN CON UN MATERIAL DE ABSORCION DE NEUTRONES, METIDO POR AMBOS EXTREMOS. POR TANTO ELLOS FORMAN UN VOLUMEN MEJORADO CONTENIENDO SUSTANCIA PELIGROSA QUE SE TRADUCE EN UNA DIGNA BARRA DE CONTROL MEJORADA Y UN AUMENTO EN EL TIEMPO DE VIDA DE SERVICIO MODERANDO Y CONTROLANDO LAS REACCIONES NUCLEARES. LA CONSTRUCCION PRESENTADA SE PUEDE USAR PARA AMBOS TIPOS DE BARRAS DE CONTROL CONVENCIONALES ASI COMO TAMBIEN PARA BARRAS DE CONTROL CONFIGURADAS PARA COLOCACIONES DE CELDAS DE CONTROL.
