Abstract

SE PRESENTA UN CONJUNTO RESORTE-Y-ESPACIADOR PARA MANTENER DERECHAS LAS BARRAS DE COMBUSTIBLE DE UN CONJUNTO COMBUSTIBLE NUCLEAR DE UN NUCLEO DEL REACTOR NUCLEAR. EL RESORTE TIENE LA FORMA DE UN BUCLE CONTINUO CON MIEMBROS PRIMERO Y SEGUNDO QUE TIENEN REGIONES DE CONTACTO CON LA BARRA DE MIEMBRO MEDIO. HAY ZONAS DE CURVATURA COLOCADAS A CADA LADO DE CADA REGION DE CONTACTO QUE SE EXTIENDEN HACIA EL INTERIOR DEL RESORTE EN BUCLE. EN LA MAYORIA DE LAS POSICIONES, EL RESORTE SE UTILIZA PARA CARGAR DOS BARRAS DE COMBUSTIBLE ADYACENTES. EN LAS CONFIGURACIONES EN QUE HAY UNA BARRA DE COMBUSTIBLE NO EMPAREJADA, HAY UNA PLACA QUE TIENE UNA LENGUETA PARA PONER EN CONTACTO EL RESORTE. EL RESORTE PROPORCIONA LA FUERZA DESEADA, POR EJEMPLO UNOS 1.124 KILOS POR BARRA DE COMBUSTIBLE EN UN PEQUEÑO ESPACIO BARRA-A-BARRA DE MENOS DE 3,45 CMS.
