Abstract

Dan je pregled različitih izvedbi sagorivih apsorbera i kratak osvrt na razvoj i svojstva paketa računalnih programa FUMACS. Opisani su postupci modeliranja izgaranja sagorivih apsorbera. Transportnim kodom FA2D simulirano je izgaranje gorivnih elemenata koji sadrže gadolinij. Pomoću modificiranog koda PSU-LEOPARD/RBI određene su ekvivalentne koncentracije bora u ovisnosti o odgoru koje reprezentiraju izgaranje stvarnog integralnog sagorivog apsorbera sa gadolinijem. Dobivenim vrijednostima ekvivalentnih koncentracija bora unaprijeđen je paket računalnih programa FUMACS/FEEC 2005 kako bi se omogućilo modeliranje izgaranja integralnih sagorivih apsorbera koji sadrže gadolinij u sljedećim radnim ciklusima NE Krško. Nova opcija programa validirana je i verificirana za preliminarni 25. radni ciklus NE Krško, slučaj B.

Abstract (english)

An overview of the various types of burnable absorbers and an outline of the development and characteristics of the FUMACS code package have been given in this thesis. Depletion modeling of integral burnable absorbers has been presented as well. FA2D transport code was used in order to accurately model depletion of the integral fuel burnable absorbers containing gadolinium. New equivalent boron concentration values that will represent the absorbing effect of the real integral burnable absorber containing gadolinium have been calculated with the modified PSU/LEOPARD program code. The new options for modeling gadolinium depletion have been introduced into the FUMACS code package. The new, upgraded, FUMACS code package was verified and validated for NPP Krško hypothetical 25th operating cycle, case B.
