Abstract

LA REJILLA, UTILIZABLE EN UN REACTOR DE AGUA A PRESION, COMPRENDE DOS JUEGOS DE PLAQUITAS ENTRECRUZADAS Y FIJADAS EN SUS PUNTOS DE CRUZAMIENTO, QUE DELIMITA CELULAS DESTINADAS A SER ATRAVESADAS UNAS POR LAPICES DE COMBUSTIBLE Y OTROS POR TUBOS GUIAS PROVISTAS DE ALETAS (26) DE AGITACION DEL REFRIGERANTE PROLONGANDO LAS PLAQUITAS HACIA ABAJO Y ORIENTADAS DE MANERA A DESVIAR EL REFRIGERANTE TRANSVERSALMENTE A SU DIRECCION DE CIRCULACION, ESTANDO PROVISTA CADA PLAQUITA DE MEDIOS DE TOPE (28), (30) EN VOLADIZO HACIA EL INTERIOR A PARTIR DE CADA UNA DE LAS CARAS DE LAS CELULAS DESTINADAS A RECIBIR LAPICES DE COMBUSTIBLE QUE DELIMITAN UN PASO SUPERIOR A LA DIMENSION DE LOS LAPICES PERO SUFICIENTEMENTE PEQUEÑO PARA IMPEDIR QUE EL LAPIZ CONTENIDO EN LA CELULA ENTRE EN CONTACTO CON LAS ALETAS. ESTOS MEDIOS LLEVAN, EN CADA PARED DOS PARTES RECORTADAS Y DEFORMADAS EN FORMA DE CUEZO (28), DECOLADAS UNA RESPECTO DE LA OTRA EN EL SENTIDO DE CIRCULACION DEL REFRIGERANTE, CUYOS SALIENTES ESTAN EN SENTIDOSOPUESTOS, Y TIENDEN A DEJAR PASAR REFRIGERANTE DE UNA DE LAS CELULAS A LA OTRA.
