The estimated subcriticality by using the conventional inverse kinetics method has large uncertainty when one-point kinetics parameters (Λ,βeff) have large uncertainty. In order to address this issue, we try utilizing the particle filter method to estimate subcriticality. In this presentation, the inverse estimation result of subcriticality using the particle filter method will be presented for a preliminary experiment where only the subcriticality changes.
