CANDU fuel uses natural uranium or slightly enriched, and it achieves low burnup compared to LWR fuel. Typical discharge burnup for LWR fuel is on the order of 50 to 60 GWd/tU, while CANDU may get to 18 to 20+ GWd/tU, so has lower fission product inventory, but I've seen older numbers like 9-12 GWd/tU. javascript programiz online https://cervidology.com
