Abstract
UN CONDENSADOR DE VAPOR CON CIRCULACION NATURAL PARA SISTEMAS DE PROTECCION DE REACTORES NUCLEARES, EN LOS QUE EXISTE UN INTERCAMBIADOR DE CALOR CON VARIOS MODULOS FORMADO CADA UNO POR UN DISTRIBUIDOR SUPERIOR, UN CONJUNTO VERTICAL DE TUBOS, Y UN DISTRIBUIDOR INFERIOR SUMERGIDO EN UN ESTANQUE A PRESION ATMOSFERICA Y CONECTADO DIRECTAMENTE A LA FUENTE DE VAPOR PRESURIZADO DE REACTOR MEDIANTE UNA LINEA DE SUMINISTRO NORMALMENTE ABIERTA Y UNA LINEA DE RETORNO DE CONDENSACION NORMALMENTE CERRADA. EL INTERCAMBIADOR, QUE SE ENCUENTRA EN UNA POSICION MAS ELEVADA QUE LA FUENTE DE VAPOR, ASEGURA LA PRESENCIA DE UNA CABEZA HIDROESTATICA EN EL CIRCUITO QUE, CUANDO SE ABRE LA LINEA DE RETORNO, CREA UN FLUJO DE CONDENSACION DESDE EL INTERCAMBIADOR A LA FUENTE DE VAPOR Y UN FLUJO DE VAPOR HACIA EL INTERCAMBIADOR, Y LA CONDENSACION DEL MISMO. EL USO EN REACTORES NUCLEARES NECESITA LA COMPATIBILIDAD CON REQUERIMIENTOS DE FIABILIDAD Y SEGURIDAD, LO QUE SE CONSIGUE MEDIANTE UNA ESTRUCTURA MODULAR, COMPONENTES SIN SOLDADURA DE LOS CUERPOS BAJO PRESION, LIMITADORES DE FLUJO INTEGRALES, Y RESTRICCIONES ESTRUCTURALES UTILES PARA LA EXPANSION TERMICA.
