Abstract: During the past half-century, the nuclear fuel cycle has generated approximately 1400 metric tons of plutonium and substantial quantities of the “minor” actinides, such as Np, Am, and Cm. The successful disposition of these actinides has an important impact on the strategy for developing advanced nuclear fuel cycles, weapons proliferation, and the geologic disposal of high-level radioactive waste. During the last decade, there has been substantial interest in the use of the isometric pyrochlore structure-type, A2B2O7, for the immobilization of actinides. Most of the interest has focused on titanate-pyrochlore because of its chemical durability; however, these compositions experience a radiation-induced transition from the crystalline-to-aperiodic state due to radiation damage from the alpha-decay of actinides. Depending on the actinide concentration, the titanate pyrochlore will become amorphous in less than 1000 years of storage. Recently, systematic ion beam irradiations of a variety of pyrochlore compo...

Journal ArticleDOI
TL;DR: In this paper, a review of the chemical behavior of fission products in steady-state operated nuclear oxide fuels is given, where the results of irradiation experiments results in the description of the release, the transport properties and the alloying and reaction behaviour of the fission product in their different chemical states.

Journal ArticleDOI
TL;DR: In this paper, a comprehensive review of radiation effects due to γ-, β- and α-decay events, as well as from actinide doping experiments and particle irradiations, on nuclear waste form glasses and crystalline ceramics was provided.

Journal ArticleDOI
TL;DR: In this article, the mechanism of the coupled anodic (fuel dissolution) and cathodic (oxidant reduction) reactions which constitute the overall fuel corrosion process is reviewed, and the many published observations on fuel corrosion under disposal conditions discussed.
