Abstract

CONJUNTO REFLECTOR DE NEUTRONES. EN EL ESPACIO IRREGULAR (13) DE UN REACTOR NUCLEAR SE POSICIONA EL CONJUNTO REFLECTOR DE NEUTRONES ENTRE UNA FORMACION (5) DE CONJUNTOS DE COMBUSTIBLE (3) ALARGADOS RECTILINEOS A TRAVES DE LOS CUALES CIRCULA EL REFRIGERANTE DEL REACTOR Y UN BARRIL CILINDRICO DE NUCLEO (7) QUE RODEA LA FORMACION; SE CARACTERIZA POR VARIOS MODULOS (15) CADA UNO DE LOS CUALES INCLUYE UN TRAVESAÑO ALARGADO (21) Y DE PLACAS ALARGADAS (23) UNIDAS A LO LARGO DE SUS BORDES LONGITUDINALES PARA FORMAR UN RECINTO ALARGADO. ESTOS RECINTOS ESTAN INSERTADOS DE FORMA MOVIL EN EL ESPACIO IRREGULAR ENTRE LA FORMACION DE CONJUNTOS DE COMBUSTIBLE Y EL BARRIL CILINDRICO DE NUCLEO LLENANDO DICHO ESPACIO.
