Tesis doctoral de Salvatore Castagna
The nuclear energy, which was developed in the last century, is used both in the military and in the civil one. One of the most important application of this type of energy is for the production of electricity for civil use. the nuclear fuel is long-lasting: a few bars of uranium can produce electrical energy up to a decade. One of the fields of study of nuclear energy is the management of the radioactive waste. This problem emerged and started to be studied in the second half of the last century. This is a very complex aspect of the use of nuclear energy because, although the combustible lasts a decade, its decay takes centuries. this thesis is a small contribute to this new branch of nuclear science. It studies some aspects of the geotechnical behaviour of salt aggregates, which can be used as filling material in the final repository of the high level radioactive nuclear waste. the fundamental rule for a nuclear waste repository is that it must work without human or mechanical help and that the same nature has to protect man against the risk of radiation for centuries. Nowadays, the most widely accepted solution in the world is the disposal in deep repositories in rock formations, often old mines and, including salt mines. It is likely that by the end of the next decade a large number of these repositories will come into operation in the countries where research in this field is more advanced. in europe we are making a common effort to study the deep repositories for nuclear waste. Thanks to common research projects granted by the european union, it is possible to investigate both the behaviour and the development of the high level radioactive waste repositories in all the involved aspects. This facilitates the diffusion of the results of these studies among all the members of the european union. this thesis deals with the thermo-hydraulic behaviour of salt aggregates due to the high temperatures produced by the nuclear waste decay. This phenomenon creates
