| Abstract: |
| In-drum drying technology, as a volume reduction technology, has been used for conditioning radioactivity wastes in NPPs abroad. Research and application practice of in-drum drying equipments, including electrical heating, hot air heating, and microwave heating devices, were introduced from the aspects of process control, drying output, water content, and volume reduction rate. It was concluded from analysis that electrical heating and hot air heating devices has higher input-output ratio, which is only suitable for flowing and thermal conductive waste equipment; although microwave heating device has higher initial investment, it has wide application range, especially applicable for organic containing waste such as base mud. |
