Abstract

CAPERUZA EXTREMA (50) DE AGARRADOR DE UNA BARRA DE COMBUSTIBLE NUCLEAR, MONTADA SOBRE UN ABARRADOR (40) DE BARRA DE COMBUSTIBLE PARA CUBRIR LAS PARTES EXTREMAS (48A) DE LAS PATILLAS (48) DE AQUELLA, Y REDUCIR AL MINIMO LOS IMPACTOS CON LAS PROTUBERANCIAS DE CELDA DE REJILLA. LAS PATILLAS (48) ESTAN DEFINIDAS POR UNAS RANURAS (46) EXTENDIDAS LONGITUDINALMENTE EN EL AGARRADOR (40), QUE PERMITEN A DICHAS PARTES EXTREMAS (48A) EXPANDIRSE Y RETRAERSE RADIALMENTE ENTRE CORRESPONDIENTES POSICIONES EXPANDIDA Y PLEGADA. LA CAPERUZA EXTREMA (50) INCLUYE UN CUERPO (52) QUE TIENE UNA PARTE ANTERIOR (56) DE ACCION DE LEVA Y UNA PARTE DE MONTAJE POSTERIOR (58). LA PARTE DE MONTAJE POSTERIOR (58) ESTA HUECA Y CONFIGURADA PARA AJUSTAR SOBRE LAS PARTES EXTREMAS (48A) DE LAS PATILLAS (48) DE AGARRADOR Y CUBRIRLAS, CON LA PARTE ANTERIOR (56) EXTENDIDA HACIA DELANTE DE AQUELLA. TAMBIEN, UNAS NERVADURAS (54) DE UNION, ESPACIADAS CIRCUNFERENCIALMENTE Y EXTENDIDAS LONGITUDINALMENTE, ESTAN DISPUESTAS POR DENTRO DELA PARTE DE MONTAJE HUECA (58) DEL CUERPO (52) SOBRESALIENDO RADIALMENTE HACIA DENTRO.
