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...

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...
