Modeling and simulation in analyzing geological repositories for high level nuclear waste

Abstract

Nuclear energy is very often used to generate electricity. But first the energy must be released from atoms which can be done in two ways: nuclear fusion and nuclear fission. Nuclear power plants use nuclear fission to produce electrical energy. Electrical energy generated in nuclear power plants does not produce polluting combustion gases like renewable energy, an important fact that could play a key role helping to reduce global greenhouse gas emissions and tackling global warming especially as electricity energy demand rises in the years ahead. This could be assumed as an ideal win-win situation, but the reverse is that the production of high-level nuclear waste outweighs this advantage. Because the safe and sustaining storage of high-level nuclear waste is not solved yet and of high political and public concern.
