AbstractDuring spent nuclear fuel reprocessing ruthenium is liable to form black ruthenium deposits on the stainless steel walls of process equipments. These deposits promote corrosion and can eventually obstruct the off-gas lines. The results of decontamination of 304L stainless steel test specimens covered with RuO(OH)

SummarySeveral ruthenium species compounds are typically encountered in waste management from nuclear fuel reprocessing operations. Ozone acting as a strong oxidizing agent in aqueous alkaline medium has some advantages for dissolving solid ruthenium deposits formed in process equipments, without generating troublesome by-products or secondary waste. This study is focused on oxidative dissolution of ruthenium(IV) oxyhydroxyde deposited on 304L stainless steel by ozone in alkaline medium. Oxidative dissolution of these deposits under various experimental conditions shows an analogous behaviour to that observed in a previous study with RuO
