Abstract

LA REJILLA ESTA COMPUESTA DE FAJAS LAS CUALES ESTAN INTERPUESTAS PARA FORMAR UNA MATRIZ DE CELULAS RECEPTORAS DE VARILLAS COMBUSTIBLES,DEFINIDA CADA UNA POR SECCIONES DE FAJAS LAS CUALES FORMAN LAS PAREDES DE LA CELULA Y DE ESTE MODO CELULAS ADYACENTES Y LA CUAL ADMITE ELASTICAMENTE LAS VARILLAS COMBUSTIBLES USANDO ESTRUCTURAS DE RESORTE DE FORMA INTEGRADA CON ELLAS. CADA VARILLA COMBUSTIBLE EMPLEA ESTRUCTURA DE RESORTE (60) COMPRENDIENDO DOS BRAZOS ALARGADOS (62) LOS CUALES SE EXTIENDEN SUBSTANCIALMENTE PARALELOS A LOS EJES LONGITUDINALES DE LAS CELULAS RECEPTORAS DE VARILLAS COMBUSTIBLES ASOCIADAS, ESTANDO ESPACIADAS LATERALMENTE, Y ESTANDO CONECTADAS INTEGRALMENTE A LA ASOCIACION CELULA - PARED DEFINIENDO SECCIONES (52) BANDA SOLO EN OPOSICION A SUS EXTREMOS, Y UN MIEMBRO CRUZADO (64) EL CUAL SE EXTIENDE DIAGONALMENRTE, PREFERIBLEMENTE A ALREDEDOR DE 45 , ENTRE LOS DOS BRAZOS Y TENIENDO ESTOS LOS EXTREMOS OPUESTOS INTEGRALMENTE CONECTADOS A EL.
