Abstract

LA REJILLA DE TRAVESAÑO, UTILIZABLE ESPECIALMENTE EN UN REACTOR DE AGUA LIGERO, CONSTA DE VARIOS JUEGOS DE PLAQUITAS (11) ENTRECRUZADAS PARA DEFINIR UNAS CELDAS DE RECEPCION DE BARRAS DE COMBUSTIBLE Y UNOS RESORTES CORRESPONDIENTES, CONSTITUIDOS POR UNA BANDA REPLEGADA EN U QUE TIENE DOS BRAZOS ACTIVOS SITUADOS A AMBOS LADOS DE UNA PLAQUITA (11), DESTINADOS A APOYARSE EN LAS BARRAS QUE OCUPAN DOS CELDAS MUTUAMENTE ADYACENTES Y SEPARADAS POR LA PLAQUITA, ENLAZADAS POR UN CIRCUITO SUPERPUESTO A LA PLAQUITA Y SOLIDARIZADAS ENTRE SI POR SOLDADURA (20) EN LA BASE DEL CIRCUITO, A TRAVES DE UNA VENTANA (18) DE LA PLAQUITA. LOS BRAZOS DE CADA RESORTE ESTAN ENLAZADOS ENTRE SI, POR UNA PARTE, POR LA SOLDDURA SITUADA EN LA BASE DEL CIRCUITO Y, POR OTRA PARTE, MEDIANTE UNOS ELEMENTOS DE BLOQUEO PURAMENTE MECANICOS DE LOS BRAZOS, UNO EN RELACION AL OTRO, Y EN RELACION A LA PLAQUITA CORRESPONDIENTE, ESTANDO DICHOS ELEMENTOS SITUADOS OPUESTOS A LA SOLDADURA EN RELACION A LA PARTE ELASTICA DEL BRAZO CORRESPONDIENTE.
