Abstract

SE PRESENTA UNA ESTRUCTURA DE REJILLA PARA SOPORTAR VARILLAS DE COMBUSTIBLE EN UN REACTOR NUCLEAR, QUE ESTA FORMADA DE UNA PLURALIDAD DE BANDAS DE REJILLA DE METAL FINAS INTERCONECTADAS (4) QUE ESTAN SOLDADAS ENTRE SI PARA SUMINISTRAR UNA RED ESTRUCTURAL DE CELDAS DE REJILLAS ABIERTAS, INTERCONECTADAS, SIMILAR A UN "DISTRIBUIDOR DE CANASTA DE HUEVOS". LAS BANDAS DE LA REJILLA ESTAN DISPUESTAS A INTERVALOS REGULARES, QUE SE CORRESPONDEN CON EL ANCHO DE UNA CELDA DE REJILLA, CON PARES DE PROYECCIONES (7) VERTICALMENTE SEPARADAS, SUBSTANCIALMENTE HORIZONTALES, EN FORMA DE MUELLES RANURADOS, Y UNA PROYECCION SUBSTANCIALMENTE EN FORMA DE X, SIMILAR A UN MUELLE (8) VERTICALMENTE INTERMEDIA A LAS PROYECCIONES HORIZONTALES. LAS PROYECCIONES EN FORMA DE MUELLE ESTAN DISEÑADAS PARA SOPORTAR Y SUJETAR LAS VARILLAS DE COMBUSTIBLE DENTRO DE LAS CELDAS DE LA REJILLA BAJO FUERZAS TANTO EQUILIBRADAS COMO DESEQUILIBRADAS QUE ACTUAN SOBRE LA VARILLA DE COMBUSTIBLE MIENTRAS ESTA EN SERVICIO, RODEADA POR REFRIGERANTE EN EL REACTOR NUCLEAR.
