Resumen
La próxima puesta en operación del reactor RA-6 en el Centro Atómico Bariloche, como facilidad de entrenamiento, investigación e irradiación, impone la necesidad de contar con un modelo de cálculo neutrónico de conocida conflabilidad. Esto permitiría hacer las evaluaciones correspondientes tanto desde el punto de vista de seguridad como de factibilidad de los experimentos. En un trabajo anterior /1/ se presentó un modelo de cálculo desarrollado en el CAB; en el presente se han incorporado al mismo algunas modificaciones para lograr una mejor simulación. Para determinar la confiabilidad de éstas, se aprovecharon determinaciones experimentales y cálculos obtenidos por el Grupo de Proyecto RP-10 /2/ para el reactor RA-2, realizando las correspondientes comparaciones.

In a previous work /1/ a calculation model developed in the CAB was presented; At present, some modifications have been incorporated to it to achieve a better simulation.
