This paper presents the TRANSURANUS burnup model for light and heavy water reactors. The light water reactor (LWR) version has been verified against a large database containing the results of electron probe microanalysis (EPMA) measurements of LWR fuels with enrichments in the range 1.38% to 8.25% and for burnups between 20000 MWd/tU and 85000 MWd/tU. Recently, this model has been extended to heavy water reactor (HWR) conditions. In total 12 radial caesium profiles, 2 neodymium profiles, 7 plutonium profiles and 22 xenon profiles were available for the verification of the new TRANSURANUS-HWR burnup model. The TRANSURANUS burnup model has been validated with great care. It models different conditions such as geometry and fuel composition for LWR and HWR in a consistent manner and the predictions made for the radial distributions of Xe, Cs, Nd (burnup) and Pu are in good agreement with the experimental evidence. The TRANSURANUS burnup model is simple and can be incorporated easily into any fuel rod analysis code.
