Abstract

Bastidor soporte de conjuntos de combustible, en un reactor nuclear, del tipo que tiene una pluralidad de rejilla axialmente espaciadas, cada rejilla teniendo una pluralidad de placas perimétricas rígidas substancialmente planas, que circunscriben una red de bandas entrelazadas, rígidas las bandas o tiras formando una estructura rígida de forma de cartón para huevos que define una disposición de aberturas, cada una adaptada para recibir una varilla de combustible nuclear transversalmente de la rejilla, caracterizado porque cuando menos una de las rejillas tiene una pluralidad de resortes anticurvatura formados integralmente sobre la superficie exterior de cada placa perimétrica y que se proyecta hacia afuera desde la misma a una distancia predeterminada, estando los resortes horizontalmente separados en forma alterna periódica con porciones substancialmente planas de la superficie externa de la placa.
