Keywords:Sodium shielding experiment, Sodium void reactivity, Data assimilation, Uncertainty

In our previous presentation, we described the results of a nuclear data sensitivity analysis of a sodium shielding experiment. In this presentation, we describe the result of a challenge to reduce the results in the sodium void reactivity by data assimilation technique using the results.
