Assessment of Long-Term Safety

The waste repository will be the final reservoir for all radioactivity generated by nuclear power. It will remain radioactive for a very long time, with some radioactivity even remaining for millions of years. As yet, complete safety analyses of waste repositories are not available. However, several attempts to approach the problem are known, and a number of systematic programs are on their way in various countries. 

Proceeding from the assumption that water will be the only vehicle that possibly can carry 

The geologic containment fails and water is allowed to enter the repository and to find its way to the solidified waste, or brine present in the repository may contact the waste. 

Radioactivity is released from the repository through contaminated water or brine entering an aquifier which is connected to circulating groundwater. 

The radioactive material released from the repository is carried to a drinking water well or
