An improved model for the corrosion of used nuclear fuel inside a failed waste container under permanent disposal conditions
نویسندگان
چکیده
An improved model for nuclear fuel corrosion inside a failed waste container has been developed. The model considers the influence of the a-radiolysis products using a full radiolytic reaction set, and demonstrates that H2O2 is the dominant oxidant. Corrosion of the fuel is modelled considering both the direct oxidation of UO2 by H2O2 and the galvanically-coupled oxidation by H2O2 reduction on noble metal (e) particles. Corrosion has been found to be very sensitive to the corrosion products of steel container, Fe and H2. The surface coverage of e-particles can significantly influence the dissolution rate. 2014 Elsevier Ltd. All rights reserved.

A model for the influence of steel corrosion products on nuclear fuel corrosion under permanent disposal conditions
A model was developed to determine the influence of steel corrosion products on a-radiolytic corrosion of spent nuclear fuel inside a failed waste container. The model takes into account the a-radiolysis of water, the reaction of radiolytic H2O2 with UO2 both directly and via galvanic coupling with noble metal particles, the reaction with H2 via galvanic coupling, and the Fenton reaction. The d...
متن کاملInteractions between Carbon Steel and Uo2 Corrosion Fronts inside a Failed Nuclear Waste Container
The corrosion of carbon steel in the chloride-dominated groundwaters anticipated inside a failed spent fuel waste container has been studied in the presence of small concentrations of added hydrogen peroxide. Solutions with peroxide concentrations in the micro-molar range were found to accelerate steel corrosion slightly leading to the formation of Fe-containing corrosion product deposits but n...
متن کاملModeling the Radiolytic Corrosion of Fractured Nuclear Fuel under Permanent Disposal Conditions
A two-dimensional model has been developed to simulate the corrosion of nuclear fuel pellets under permanent waste disposal conditions in a steel vessel with a corrosion-resistant copper shell. The primary emphasis was on the corrosion behavior within cracks with various dimensions. It was shown that a simplified α-radiolysis model which only accounts for the radiolytic production of H2O2 and H...
متن کاملRoles of Radiolytic and Externally Generated H2 in the Corrosion of Fractured Spent Nuclear Fuel.
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 ...

Swelling clays play a major role in current concepts for the underground disposal of high-level nuclear waste in deep geological formations. In one of the multi-barrier concepts for preventing the escape of radioactive substances from a high-level nuclear waste repository, the barrier consists of a copper container, compacted bentonite as buffer and backfill (the engineered barrier), and the re...
