Abstract

LA REJILLA ESTA COMPUSTA DE TIRAS INTERFOLIADAS PARA FORMAR UNA MATRIZ DE BARRAS DE COMBUSTIBLE, QUE CONTIENEN CELULAS DE REJILLAS, DEFINIDA CADA UNA POR SECCIONES DE TIRAS QUE TIENEN ESTRUCTURAS QUE SOPORTAN Y ENCAJAN BARRAS DE COMBUSTIBLE FORMADAS INTEGRAMENTE CON ELLAS. LAS ESTRUCTURAS (60, 78) QUE ENCAJAN Y SOPORTAN BARRAS DE COMBUSTIBLE EN LAS DISTINTAS SECCIONES (52) DE TIRAS QUE DEFINEN CELULAS INCLUYEN HOYUELOS (78) ARQUEADOS QUE ESTAN SESGADOS, DE MANERA QUE HACEN MINIMO EL RIESGO DE DEFORMACION DE LOS HOYUELOS DURANTE LA INSERCION DE LAS BARRAS DE COMBUSTIBLE, Y LA IMPEDANCIA DE FLUJO PRESENTADA POR LOS HOYUELOS AL FLUJO DE REFRIGERANTE A TRAVES DE LAS RESPECTIVAS CELULAS DE REJILLA. LAS ESTRUCTURAS QUE ENCAJAN Y SOPORTAN LAS BARRAS DE COMBUSTIBLE, PREFERIBLEMENTE INCLUYEN MUELLES DE REJILLA (60), QUE TIENEN PARTES (64) DE MUELLE QUE ENCAJAN LAS BARRAS DE COMBUSTIBLE, QUE TAMBIEN SON SESGADAS.
