文摘

The influence of Mo contained in SS on CsOH chemisorption was investigated. Cs chemisorbed deposits were submitted to revaporization tests. CsFeSiO4 was the main chemisorbed compound and stable at high temperature. Cs2MoO4 and Cs4Fe(MoO4)3 were the Cs-Mo deposited phases detected. Cs-Mo deposits re-vaporization can contribute to the accident late stage release.
