Reactivity of Peroxynitrite: Implications for Hanford Waste Management and Remediation

PDF Version Also Available for Download.

Description

To provide quantitative mechanistic information relevant to: (i) the extent and nature of radiation-induced chemical modification of the nuclear waste that occurs during storage and (ii) the extent of accumulation of peroxynitrite in the waste and its potential use in remediation. Within this context, the specific goals are: To determine the radiochemical yields of peroxynitrite in mixtures simulating the various phases (salt cake, slurry, supernatant) of nuclear waste; Through mechanistic studies of metal-, proton-, and CO2-catalyzed oxidations by peroxynitrite, estimate the extent of peroxynitrite-mediated oxidative degradation of organic waste components and determine the feasibility of using peroxynitrite for the destruction ... continued below
