The fire and explosion incident occurred at the Bituminization Demonstration Facility of the Tokai Reprocessing Plant on march 11th, 1997. For investigation of Bituminization Demonstration Facility Incident and prevention relapse, Investigation Group for Bituminization Demonstration Facility incident was set up. It has been investigated the situation at the time of incident was occurred. The result of investigated was presented for Science and Technology Agency. This report is arranged the result of investigated the situation for investigation and prevention relapse.

In order to establish deterioration diagnosis technology for surface coating materials, we examined the measurement method and analysis method. The local thermal diffusivity could be measured by the laser spot periodic heating radiation thermometry method. In addition, it was also measured the thermal diffusivity by the xenon flash method to compare that by the laser spot periodic heating radiation thermometry method. A two-layer analytical formula was constructed for the coating sample, because there is a possibility that single-layer analysis may not give accurate results. As a result of measurement at room temperature, the thermal diffusivity decreased remarkably in the thickness direction measurement when the coating surface was placed on the detection surface side. On the other hand, the thermal diffusivity kept remained when the coating surface was placed on the heating surface side.
