Fattahi, Z. Andriambololona] The aim of the present work is to quantify the influence of alpha radioactivity of 225Ac doped UO2 on the dissolution rate under reducing conditions at pH 6. The doped or undoped material was prepared by precipitation and the size of particles was about 3nm. The total alpha activity of the doped material was about 2000MBq g-1 UO2, about 4 times higher than that of 15years old spent fuel. The solution was kept under reducing conditions during the experiment by permanent electrochemical reduction under inert atmosphere. The results showed that the dissolution rate of doped material was a function of alpha activity and thus a function of the dose. © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Mennecart Thierry aut Grambow Bernd aut Fattahi M. aut Andriambololona Z. aut Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/9-11/2004(2004-11-01), 611-615 0033-8230 92:9-11/2004<611 2004 92 ract https://doi.org/10.1524/ract.92.9.611.55010 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.92.9.611.55010 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Mennecart Thierry aut NATIONALLICENCE 700 1- Grambow Bernd aut NATIONALLICENCE 700 1- Fattahi M. aut NATIONALLICENCE 700 1- Andriambololona Z. aut NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/9-11/2004(2004-11-01), 611-615 0033-8230 92:9-11/2004<611 2004 92 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
