Pulse radiolysis with spectrophotometric and conductometric detection was utilized to study the formation and reactions of radicals from benzene and dienes in aqueous solutions. The benzene OH adduct, *C6H6OH, reacts with O2 (k = 3 x 10(8) L mol(-1) s(-1)) in a reversible reaction. The peroxyl radical, HOC6H6O2*, undergoes O2*- elimination, bimolecular decay, and reaction with benzene to initia...

A 2-D model for the corrosion of spent nuclear fuel inside a failed nuclear waste container has been modified to determine the influence of various redox processes occurring within fractures in the fuel. The corrosion process is driven by reaction of the fuel with the dominant α radiolysis product, H2O2. A number of reactions are shown to moderate or suppress the corrosion rate, including H2O2 ...

Using a recently developed approach for numerical simulation of radiation-induced oxidative dissolution spent nuclear fuel, we have explored the impact three possible contributions to inhibiting effect molecular hydrogen. The are (1) on oxidant production in irradiated water, (2) reduction oxidized uranium catalyzed by noble metal inclusions (fission products) and (3) reaction with surface-boun...

1. Hydrated electrons produced by pulse radiolysis were used to study the interaction of polyanionic glycosaminoglycans and related compounds with the counterions Methylene Blue and cetylpyridinium chloride. 2. The effect of added salt (potassium chloride) on the interaction indicates that the relative binding affinities, with respect to the types of anionic site present, increases for both cou...

The radical reactions in the liquid phase y-radiolysis of propane have been studied from -130 to 35°C and compared with the gas-phase radiolysis at 35°C. Oxygen was used as a scavenger 10 separate thermal radical yields, and effects· of phase and temperature on the radical yields were assessed. The gas-liquid phase change (a) decreases total decomposition by about 14 %, (b) increMCs disproporti...

The radiolysis of purified water, its mixture with carbon dioxide, and also the addition salt potassium chloride isotope (40KCl) plant mass to this system were carried out in order study mechanism radiolytic processes taking place presence natural (40K) contained it. It revealed that 40KCl system, formation trace amounts molecular hydrogen is observed (in accord an insignificant dose radiation ...

Solvated electrons are typically generated by radiolysis or photoionization of solutes. While plasmas containing free electrons have been brought into contact with liquids in studies dating back centuries, there has been little evidence that electrons are solvated by this approach. Here we report direct measurements of solvated electrons generated by an atmospheric-pressure plasma in contact wi...
