Abstract

SE DA A CONOCER UN ESPACIADOR DE CASQUILLO MEJORADO PARA SU UTILIZACION CON DISPOSICION DE BARRAS DE COMBUSTIBLE DE ALTA DENSIDAD DENTRO DE HACES DE COMBUSTIBLE DE UN REACTOR NUCLEAR DE AGUA A PRESION. LOS CASQUILLOS ESTAN CONSTRUIDOS EN EMPAREJAMIENTOS QUE SE CORRESPONDEN. CADA CASQUILLO (42,44) ESTA DIVIDO EN MITADES SUPERIORES E INFERIORES (42A,42B,44A,44B). UNA MITAD (42B,44B) DEL CASQUILLO TIENE SUS LADOS QUE SE RETIRAN CON LAS PAREDES. LA OTRA MITAD (42A,44A) DEL CASQUILLO SE ENCUENTRAN EN SU LUGAR. LOS PARES DE CASQUILLOS ESTAN CONFRONTADOS CON UN CASQUILLO INVERTIDO CON RESPECTO AL OTRO Y CON CADA PARED DE CASQUILLO COMPLETA QUE SE ENCUENTRA YUXTAPUESTA CON LA OTRA MITAD DEL CASQUILLO Y A SU VEZ ESTA MITAD DEL CASQUILLO CON LA PARED FALTANTE. PREFERENTEMENTE, Y EN EL PUNTO DE TANGENCIA EN LOS PARES DE CASQUILLOS, SE DEFINE UNA APERTURA (62) PARA RECIBIR Y CONFINAR UN RESORTE (12) DE LAZO DOBLE DEL TIPO "H". EL CIERRE INCLUYE CASQUILLOS QUE DISPONEN DE UN CONTORNO CIRCULAR PARA LAS BARRAS DE COMBUSTIBLE Y CASQUILLOS QUE DISPONEN DE UN CONTORNO DE SECCION OCTAGONAL PARA LAS BARRAS DE COMBUSTIBLE. CADA ELEMENTO DEL PAR DE CASQUILLOS ESTA DISPUESTO DE FORMA SIMETRICA Y COMPLETAMENTE INTERCAMBIABLE PARA SUMINISTRAR UN CONJUNTO CONVENIENTE PARA AMBOS Y UNA DISPOSICION PEQUEÑA DE LAS PARTES ENSAMBLADAS.
