Plutonium exists in the environment as a result of the nuclear fuel and weapons cycle and nuclear weapons testing. Carbonate and hydroxide are ubiquitous in the environment while chloride is a principal component in brines such as those native to the Waste Isolation Pilot Plant (WIPP) site. Thus, the characterization of plutonium complexes formed with CO[sub 3][sup 2-], OH[sup -], and Cl[sup -] is important for predicting the behavior of plutonium in the environment. Plutonium(VI) is known to form under oxidizing conditions, and we are investigating the structure, solubility and speciation of plutonium(VI) carbonates and hydroxides. © 2000 American Institute of Physics.

    Corrosion and pitting have been observed in headspace regions of stainless steel containers enclosing plutonium oxide/salt mixtures. These observations are consistent with the formation of a corrosive gas, probably HCl, and transport of that gas to the headspace regions of sealed containers. The...

    Polymeric Pu(IV) at concentrations from 10 to 10 M in solutions with pH ∼8, i.e., under the conditions close to those in natural waters, does not disproportionate, and its polymeric species are stable. If Pu(VI) is present in solution under these conditions simultaneously with polymeric...
