Abstract

LA CANTERA INFERIOR (10) SE COMPONE DE UN ELEMENTO TRANSVERSAL (12) QUE PRESENTA UNA ESTRUCTURA EN FORMA DE CAJON. EL ELEMENTO TRANSVERSAL VA DOTADO DE UNA ESTRUCTURA RETICULADA (13) RESISTENTE A LA FELXION, LIMITADA EXTERIORMENTE POR UN MARCO (14) CUYA SECCION CORRESPONDE SENSIBLEMENTE A LA SECCION TRANSVERSAL DEL CONJUNTO. LA ESTRUCTURA (13) PRESENTA CELULAS DE GRAN DIMENSION. EL ELEMENTO TRANSVERSAL LLEVA DOS O MAS UNA PLACA DE RETENCION (20) AGUJEREADA DE PEQUEÑAS ABERTURAS SUPERPUESTAS Y FIJADAS A LA ESTRUCTURA RETICULADA (13) PARALELAMENTE A ESTA Y CON UN ESPACIAMIENTO B, PARA CONSTITUIR LA PARTE SUPERIOR DE LA CANTERA (10) Y DELIMITAR UN ESPACIO LIBRE DE TRAMQUILIZACION DEL AGUA DE REFRIGERACION DEL REACTOR Y DE RECUPERACION DE RESIDUOS ARRASTRADOS POR EL AGUA, QUE CONSTITUYE LA PARTE CENTRAL HUECA DE LA ESTRUCTURA EN FORMA DE CAJON.
