Abstract
SE PRESENTA UN METODO Y UN DISPOSITIVO PARA GUIAR UN FLUJO DE REFRIGERANTE EN UN REACTOR NUCLEAR DE AGUA LIGERA. EL GUIADO DEL FLUJO DE REFRIGERANTE SE REALIZA DENTRO DE UNA SECCION DE CRUCE MEZCLADORA QUE COMPRENDE CUATRO SUB-REGIONES ORTOGONALMENTE DISPUESTAS (1, 1A, 1C), QUE A SU VEZ COMPRENDEN PARTES O LA TOTALIDAD DE MONTAJES DE COMBUSTIBLE (1). EN CADA SUB-REGION (1, 1A, 1C) SE DISPONE AL MENOS UN NIVEL QUE COMPRENDE SEPARADORES (7) QUE ESTAN PROVISTOS DE MIEMBROS DE CONTROL DEL FLUJO (12) ADAPTADOS DE MANERA QUE EL REFRIGERANTE SEA GUIADO DESDE UNA SUBREGION (1, 1A, 1C) A UNA SUB-REGION ADYACENTE (1, 1A, 1C), ECUALIZANDO DE ESTA FORMA LA ENTALPIA DEL REFRIGERANTE EN LA SECCION DE CRUCE MEZCLADORA.
