Description

Impact of ultrasonic field action on the process of dissolution of nuclear fuel elements on the basis of U-Al-Si alloys in nitric acid and alkali media is studied. It is shown that application of ultrasonics essentially increases the velocity of alloy dissolution due to mechanical destruction of samples into fragments and their further erosion and dispersion. The supersonics facilitate destruction of the Al2O3 oxide film, which makes it possible to avoid application of generally used Hg(2) compounds

Abstract (Russian)

Исследовано влияние воздействия ультразвукового поля на процесс растворения твэлов на основе сплавов U-Al-Si в азотнокислых и щелочных средах. Показано, что применение ультразвука существенно увеличивает скорость растворения сплава благодаря механическому разрушению образца на более мелкие осколки и их дальнейшей эрозии и диспергированию. Ультразвук также способствует разрушению оксидной пленки Al2O3, что позволяет избежать использования обычно применяемых соединений Hg(2)
