Plutonium (Pu) in the subsurface environment can transport in different oxidation states as
an aqueous solute or as colloidal particles. The transport behavior of Pu is affected by the …

Abstract Tetravalent actinides, An (IV), are usually assumed to be little mobile in near-neutral
environmental waters because of their low solubility. However, there are certain …

▪ Abstract The nation has over 40,000 metric tonnes (MT) of nuclear waste destined for
disposal in a geologic repository at Yucca Mountain. In this review, we highlight some of the …

The influence of montmorillonite colloids on the mobility of 238 Pu, 233 U and 137 Cs
through a chalk fracture was investigated to assess the transport potential for radioactive …

This is the first book to cover actinide nano research. It is of interest both for fundamental
research into the chemistry and physics of f-block elements as well as for applied …

Plutonium is one of the most toxic components of spent nuclear fuel and of nuclear wastes,
which is characterized by very complex chemical behaviour both in engineering processes …

Migration of radionuclides via colloid-facilitated transport is an important component of
nuclear repository performance models. 137 Cs sorption to bentonite colloids follows multi …

Aqueous Pu concentrations and oxidation state transformations as a function of pH were
quantified and compared between sorption/desorption studies and literature solubility …

Laboratory batch sorption experiments were used to investigate variations in the retardation
behavior of redox-sensitive radionuclides. Water-rock compositions were designed to …

Increasing observations of subsurface actinide transport has reinforced the need for a basic
geochemical and hydrologic understanding of how these contaminants are transported in …
