Measurements and experiences during conversion of DR 3 to low enriched silicide fuel
Description
DR 3 has been operated with 8 U3Si2 19, 75% enriched 180g U235 fuel elements in the core from October 14, 1988 to May 5, 1990, the remaining part of the core being 150g U235 HEU fuel elements. From May 5, 1990, LEU fuel elements, only, have been loaded for fuel replacement. Full LEU-core will be reached December 1990. During every mixed core operation cycle predictions of flux-, power- and burn-up distributions have been performed by means of the 3-dimensional DR3-SIM code and the calculations have been verified by measurements of thermal and fast flux distributions in each fuel element and reactivity changes by each fuel element replacement. Statistics and trends deducted from this comprehensive material is presented in the report. No major problem connected to the conversion has been experienced so far
