The second of three planned versions of the COPERNIC fuel performance code is nearing completion. The COPERNIC code development effort was launched in 1992 as part of a larger Framatome effort to develop a new generation of fuel-management codes. The COPERNIC code was developed primarily to produce accurate steady-state and transient extended-burnup fuel performance predictions and incorporate advanced materials. The COPERNIC code predictions are applicable to UO{sub 2}, UO{sub 2}-Gd{sub 2}O{sub 3}, and mixed-oxide fuel types. The first version of the code, which was completed in 1995 and is currently being licensed in France, was extensively benchmarked to moderately high burnups. The second version contains several improved models and is also being benchmarked to moderately high burnups. The third version will be benchmarked to very high burnups. Model highlights and measured-to-predicted data comparisons for the second version are presented in this paper.
