Si source for Cs-bearing particle formed by Fukushima-Daiichi NPS accident has yet to be revealed. Stainless steel is possible Si source since it is used as structure material in the reactor and includes Si. In this study, Si vaporization behavior was evaluated by investigation of Si behavior in oxide layer formed in steam atmosphere at 1473 K.
