The application of UWB1 nuclear fuel depletion code on a CANDU fuel bundle

Further improvement on the UWB1 code is ongoing. The results showed that UWB1 nuclear fuel depletion code is capable to calculate fuel depletion of CANDU fuel bundle with and without burnable absorbers. As expected, the accuracy of the UWB1 code is lower than the other codes. This paper recommends that UWB1 code be considered as a tool for supporting fuel design assessment, since discrepancies are comparable and the code is one to two orders of magnitude faster than other depletion codes.
