Abstract

Many physical and chemical properties ofnuclear fuel are currently modelled in the fuel performance codes with empirical correlations with several free parameters rather than exact models.On one hand,the macroscopic phenomena are so complex that it is difficult to come up with precise models forfuel performance codes, and on the other hand, the microscale physical and chemical phenomena are not understood well enough. We present here a concept for sinteringsimulated nuclear fuel samples for separate effect tests, which can help in the model development and understandingofunderlying physics and chemistry. We also review previous work done at VTT with simulated fuels that has been the basis for the current work.
