The title of this presentation is “Physical start-up tests calculations for Dukovany and Temelín NPP using MOBY-DICK macrocode“. The presentation further extends topic presented on 27th Symposium of AER in Munich. Three tests are discussed: “SCRAM” test for Temelín NPP and “Weight of 6th group of control assemblies” test and “Thermal reactivity coefficient” test for Dukovany NPP. The first part describes MOBY-DICK macrocode and auxiliary functions used for calculations, as well as methodology of individual tests calculations, while the second part presents results of calculations and comparison with experimental values. “SCRAM” test calculation was performed for Temelín NPP Unit 1 Cycle 13 and Unit 2 Cycle 12, “Weight of 6th group of control assemblies” test calculation was performed for Dukovany NPP Unit 1 Cycle 33 and “Thermal reactivity coefficient” test calculation was performed for Dukovany NPP Unit 1 Cycle 29, Unit 2 Cycle 28, Unit 3 Cycle 27 and Unit 4 Cycle 27.
