Keywords:Nuclear data adjustment method, Data assimilation, Unscented Transform, Deterministic sampling method

We developed a new nuclear data adjustment method using a deterministic sampling method based on the Unscented transformation. Compared with the conventional method using probabilistic sampling, the nuclear data adjustment is feasible with less computational cost.
