Abstract
UN CONJUNTO DE BARRAS ABSORBENTES QUEMABLES PARA SU INSERCION EN SITIOS PREDETERMINADOS EN UN ELEMENTO COMBUSTIBLE DE UN REACTOR NUCLEAR. CONSTAN DE UNA SECCION TUBULAR INTERMEDIA HUECA (60) QUE CONTIENE MATERIAL ABSORBENTE QUEMABLE (72), CON TAPAS TERMINABLES (74, 76) EN SUS EXTREMOS, HABIENDO UN MUELLE (78) QUE SE SUJETA POR TAPAS. LAS SECCIONES TERMINABLES (68, 70) TIENEN TAPONES TERMINALES (54, 58) QUE LAS SELLAN. LAS SECCIONES DE CAPA BARRA PUEDEN TENER VALORES DIFERENTES MIENTRAS QUE LAS LONGITUDES SON ESTANDARIZADAS, DE FORMA QUE LA LONGITUD AXIAL COMBIANDA ES LA MISMA PARA TODAS LAS BARRAS. EL OBJETIVO DE LA INVENCION ES MAXIMIZAR EL FACTOR DE PICO EN EL NUCLEO DE UN REACTOR NUCLEAR MEJORANDO ADEMAS LOS TIEMPOS DE RESPUESTA EN SITUACIONES DE EMERGENCIA.
