Abstract
SE PRESENTA UN CONJUNTO INTEGRADO DE TORRE (14) DE UNA VASIJA DE REACTOR NUCLEAR (10) QUE INCLUYE UNA TAPA DE CIERRE (20) CON CONJUNTOS CRDM (22) QUE SE EXTIENDEN HACIA ARRIBA DESDE LA TAPA. SOBRE LA TAPA DE CIERRE SE DISPONE UN SOPORTE SISMICO CRDM (24) QUE PROPORCIONA EL APOYO LATERAL PARA LOS CONJUNTOS CRDM (22). EL SOPORTE SISMICO (24) TIENE TAMBIEN UNOS ORIFICIOS DE AIREACION (60, 62) COMUNICANTES CON EL INTERIOR DE UNA ENVOLTURA (32), DONDE SE HALLAN LOS CRDM (22), QUE SE EXTIENDE HACIA ARRIBA DESDE LA TAPA DE CIERRE (20) HASTA EL SOPORTE SISMICO (24). LA ENVOLTURA (32) TIENE UNA ABERTURA DE AIREACION (96) QUE COMUNICA DIRECTAMENTE CON LA ATMOSFERA, DE FORMA QUE LA TAPA DE CIERRE (20), LA PROPIA ENVOLTURA (32) Y EL SOPORTE SISMICO (24) DEFINEN UN CONDUCTO PARA EL PASO DIRECTO DEL AIRE A LA ATMOSFERA A TRAVES DE LA ABERTURA DE AIREACION, SIN LARGAS CANALIZACIONES Y POR TANTO CON MENOR CAIDA DE PRESION, REQUIRIENDO DE ESTA FORMA MUCHA MENOS ENERGIA.
