Abstract

ENSAMBLAJE DE COMBUSTIBLE PARA UN REACTOR NUCLEAR DE AGUA LIGERA, QUE COMPRENDE UNA MULTITUD DE VARILLAS DE COMBUSTIBLE VERTICALES (10, 42), QUE SE DISPONEN, ESPACIADAS ENTRE SI EN LA DIRECCION LATERAL, ENTRE UNA PLACA DE SUJECCION (11, 44) Y UNA PLACA DE SUJECCION SUPERIOR (12, 43), ESTANDO PROVISTA LA PLACA DE SUJECCION DEL FONDO CON AGUJEROS DIRECTOS A PARTE PARA CONDUCIR EL AGUA A TRAVES DE LA PLACA DE SUJECCION DEL FONDO Y AL INTERIOR DE LOS ESPACIOS QUE HAY ENTRE LAS VARILLAS DE COMBUSTIBLE. CONFORME A ESTA INVENCION, LOS AGUJEROS DE PARTE A PARTE EN LA PLACA DE SUJECCION DEL FONDO TIENEN PARTES (50A, 50B, 70A, 70B) CUYAS LINEAS CENTRICAS ESTAN DESPLAZADAS ENTRE SI EN LA DIRECCION LATERAL O FORMAN UN ANGULO ENTRE SI (FIGURA 7).
