As part of the effort to develop an analytical method to evaluate the effect of fuel fragmentation, relocation and dispersal (FFRD) for high burnup fuel on core coolability in a LOCA, simulations of Halden LOCA test using coupled TRACE/FRAPTRAN code were conducted. We present the results using different fuel cladding deformation models.
