In the accident of Fukushima Daiichi nuclear power station, the release of Sr from fuel would be enhanced both by the formation of volatile SrCl₂ and steam starvation condition, which can lead to Sr chemical reaction with Zircaloy (Zry) cladding. This study aimed at investigating basic aspects of the Sr-Zry chemical reaction by experiment and chemical equilibrium calculation. The first result indicated that formation of SrZrO₃ could be limited in the case of SrCl₂ formation.
