Abstract
UNA REJILLA DE ESPACIAMIENTO PARA UN ENSAMBLAJE DE COMBUSTIBLE NUCLEAR TIENE VARIAS PLAQUETAS METALICAS (22) ENTRECRUZADAS QUE DEFINEN UNAS CELULAS INDIVIDUALES (24) DESTINADAS A RECIBIR CADA UNA UN LAPIZ DE COMBUSTIBLE (26). UNAS ALETAS (30) DE MEZCLA QUE SE EXTIENDEN A PARTIR DE UNA ARISTA, ALTERNATIVAMENTE A UNO Y OTRO LADO DE LA PLAQUETA (22), EN LAS CELULAS INDIVIDUALES (24). LAS ALETAS (30) TIENEN UNA FORMA TAL QUE NO REBASAN, EN EL SENTIDO AXIAL, LA ENVOLTURA VIRTUAL DE LAS PLAQUETAS.
