Abstract

CONJUNTO DE COMBUSTIBLE NUCLEAR DOTADO DE UNA PLURALIDAD DE REJAS SEPARADORAS (16) DE LAS BARRAS DE COMBUSTIBLE (18) Y DE UNOS FIADORES (46, 48) DISEÑADOS PARA APLICAR A CADA BARRA DE COMBUSTIBLE (18) UNA FUERZA PREDETERMINADA CAPAZ DE IMPEDIR EL DESPLAZAMIENTO Y LA VIBRACION LATERALES DE DICHAS BARRAS (18). LA FUERZA PREDETERMINADA DISEÑADA PARA LOS FIADORES DE LA REJA DE EXTREMIDAD (16 U) SITUADA MAS CERCA DE LA ESTRUCTURA DE EXTREMIDAD DE SALIDA DE REFRIGERANTE (22) DEL CONJUNTO DE COMBUSTIBLE ES INFERIOR A LA FUERZA PREDETERMINADA DISEÑADA PARA LOS FIADORES DE LA REJA DE EXTREMIDAD (16 L) SITUADA MAS CERCA DE LA ESTRUCTURA DE EXTREMIDAD DE ENTRADA DE REFRIGERANTE (12) PARA PERMITIR LA ELONGACION RECTILINEA DE LAS BARRAS DE COMBUSTIBLE QUE TIENDEN A CRECER AXIALMENTE. ESTA INVENCION CONTRIBUYE A EVITAR EL PROBLEMA DE LA CURVATURA DE LAS BARRAS DE COMBUSTIBLE.
