The long-term behaviour of toxic and radioactive solutes in groundwater has become a subject of great interest in connection with investigation of environmental releases of hazardous chemicals and wastes. The transport, distribution and fate of contaminants in groundwater strongly depend on...

In the past few decades, the problem of dealing with inadvertently contaminated steel has turned out to be of real importance in several countries. Typically, this problem originates at a foundry which recycles scrap iron: indeed, in several instances it happened that the material to be smelted...

The methodologies employed in the probabilistic safety assessment (PSA) of hazardous engineering systems have reached a high level of maturity. However, a few issues are still worth of further investigation in order to increase the confidence in the results obtained. In this view, in the past...

Regulations for the long-term disposal of high-level radioactive wastes command that the performance of the disposal facility be assessed for very long periods of time and quite extensive spatial scales. By nature, then, the analysis of the performance of a disposal facility relies on the...

This paper addresses the problem of radionuclides transport through the artificial porous matrices constituting the engineered barriers of a permanent deposit for radioactive wastes under design by the Italian Agency for Energy and Environment (ENEA). The complexity of the phenomena involved,...
