Abstract

PROCEDIMIENTO PARA LA EXPLOTACION DE UN REACTOR NUCLEAR DE AGUA LIGERA. CARACTERIZADO PORQUE SE PREVEN LOS EQUIPOS INTERNOS DEL REACTOR DE MANERA QUE PUEDAN RECIBIR INDISTINTAMENTE CONJUNTOS COMBUSTIBLES DE UN PRIMER TIPO, QUE PERMITEN FUNCIONAR CON SUBMODERACION CON COEFICIENTE DE CONVERSION ELEVADO, Y CONJUNTOS COMBUSTIBLES DE UN SEGUNDO TIPO QUE PRESENTAN TUBOS-GUIA DESTINADOS A PERMITIR UNA VARIACION DE ESPECTRO DEL CAMPO TERMICO AL CAMPO INTERMEDIO; Y PORQUE SE REEMPLAZA AL MENOS UNA PARTE DE LOS CONJUNTOS DE UN TIPO POR CONJUNTOS DE OTRO TIPO, AL FINAL DEL FUNCIONAMIENTO DEL NUCLEO. DE APLICACION EN LOS REACTORES NUCLEARES DE AGUA LIGERA.
