This work deals with the experimental evaluation of the thermal conductivity of a\udconcrete matrix to be used for embedding LILW bituminised Wastes into the packaging system.\udSuch a type of packaging, identified with the acronym CP5.2, has been also qualified by\udexecuting at the Lab. Scalbatraio of Dep. of Civil and Industrial Engineering of the University\udof Pisa, an experimental test campaign accordingly to the IAEA regulations.\udIn particular, the knowledge of the thermal conductivity is important because of the fire or\udfurnace test to carry out in oven at 800 °C for 30 minutes. These data allowed to simulate pretest\udconditions and to set up safety and operational fire test procedures.\udThe concrete thermal conductivity was obtained by performing hot wire tests on cylindrical\udconcrete samples for temperatures ranging from 100° to about 800°C.\udThermal conductivity is determined at steady state condition. Results indicate a monotonically\udreduction of the thermal conductivity as the temperature increases. The comparison with\udconcrete thermal conductivity data available in literature indicates a quite good agreement.\udFinally, visual and X-ray inspection of sample did not highlight the presence of micro/macro\uddamages that would have affected the thermal performance of the concrete under study
