Abstract

Rejilla para conjunto de combustible de reactor nuclear que incluye una pluralidad de tiras dispuestas en un marco periférico e intercaladas las unas con las otras para formar una estructura de rejilla que incluye compartimientos individuales adaptados para recibir barras de combustible y tubos de guiado de barras de control, y unos muelles que forman parte integrante de dichas tiras y sobresalen hacia el interior en cada compartimiento para mantener dichas barras de combustible separadas las unas de las otras, estando dicha rejilla caracterizada porque cada uno de dichos muelles (22, 26) consiste en una sección troquelada en una tira (12, 14) y ondulada de modo que presente una forma generalmente sinusoidal, constituyendo por lo menos un saliente central (38, 40) destinado a entrar en contacto con la superficie de una barra de combustible (18) adaptada para situarse a través de un compartimiento (16), en un lado de una tira (12, 14), y por lo menos dos salientes de soporte (34) en las extremidades opuestas de dichos saliente central y que se extienden en un compartimiento (76) en el otro lado de dicha tira (12, 14).
