Abstract
In these studies the isotopic inventories and corresponding activities of important nuclides for different fuel cycles of a CANDU reactor have been compared. The calculations have been performed using the computer code WIMSD4. The isotopic inventories and activities have been calculated versus the fuel burn-up for the natural UO<sub>2</sub> fuel, 1.2% enriched UO<sub>2</sub> fuel and for the 0.45% PuO<sub>2</sub>-UO<sub>2</sub> fuel. It is found that 1.2% enriched uranium fuel has the lowest activity as compared to other two fuel cycles and vice versa for the 0.45% PuO<sub>2</sub>-UO<sub>2</sub> fuel.
