In order to ensure the long-term safety of the vitrified radioactive waste, the relationship between number of stirring and characteristics of material strength after melting the raw material glass and simulated vitrified radioactive waste were investigated by synchrotron radiation X-rays. As a result, it was clarified that the internal defects in simulated vitrified radioactive waste increased and the material strength of simulated vitrified radioactive waste was suitable as increasing the number of stirri...

The high level radioactive liquid waste is analyzed for the vitrification process control and the vitrified waste quality in the hot cell of Tokai Vitrification Facility, Tokai Reprocessing Plant. There are 8 Master-slave manipulators, 7 lighting equipment, an electronic balance, and an inductively coupled plasma-optical emission spectrometer used for remote operation, securing visibility, total oxide analysis, and elemental analysis in the analytical hot cell. These equipment and analytical apparatus must ...

In order to confine radioactive materials inside the building, buildings, hot-cells and vessels are maintained at a lower air pressure than the atmospheric environment in Tokai Reprocessing Plant. For this purpose, air exhausters are continuously operated. However, during the periodic maintenance of the electric substation in September 2011, the incident in which the vessel ventilation including the spare machine of the highly radioactive liquid waste storage tank have not been started. In this paper, the c...
