Metal corrosion studies with the fluorosulphonic acid–antimony pentafluoride superacid system

Autor: Scott A. Kinkead, R. J. Kissane, P. Gary Eller, Robert J. Hanrahan, Larry R. Avens, Kent D. Abney

Publikováno v: Journal of Alloys and Compounds. 365:134-137

Because of their rapid dissolution of many actinide metals and refractory oxides, superacids such as HSO 3 F/SbF 5 have potential applications in actinide processing. However, material compatibility must first be addressed because of the highly corro

Oxidation Chemistry of a Uranium(III) Aryloxide

Autor: Larry R. Avens, David M. Barnhart, Wayne H. Smith, Carol J. Burns, Steven D. McKee

Publikováno v: Inorganic Chemistry. 33:4245-4254

The oxidation chemistry of the uranium(III) aryloxide complex U(OAr){sub 3} (OAr=2,6-di-tert-butylphenoxide) has been explored with a variety of one-electron oxidants. Oxidation of U(OAr){sub 3} with either AgBF{sub 4} or AgPF{sub 6} produces the ura

Aqueous and pyrochemical reprocessing of actinide fuels

Autor: L. Mac Toth, Larry R. Avens, Walter D. Bond

Publikováno v: JOM. 45:35-39

Processing of the nuclear fuel actinides has developed in two independent directions—aqueous processing and pyroprocessing. Similarities in the two processes, their goals, and restraints are indicated in brief parallel descriptions along with disti

Publikováno v: Separations of f Elements ISBN: 9781489914088

Magnetic separation is a physical separation process that segregates materials in a mixture on the basis of magnetic susceptibility. Because all actinides and their compounds and fission products are paramagnetic, and most host materials such as wate
