Calculation of NPP Krsko core design characteristics during 27th cycle

U radu je dan prikaz osnovnih karakteristika programa PARCS i načina formiranja ulaznih podataka. Posebno su analizirani udarni presjeci u PMAX formatu i detaljno u FAXS formatu. Proračunate su projektne vrijednosti jezgre tijekom izgaranja za vrijeme 27. ciklusa NEK. Određeni su podaci za model točkaste kinetike u programu RELAP5 za ciklus 27. Analizirana je mogućnost uključivanja izmjena napravljenih na FER ZVNE u novu verziju programa PARCS 3.2 kao način prevođenja podataka o udarnim presjecima iz formata FAXS u format PMAXS.The thesis gives overview of PARCS code main characteristics and describes procedure for input data preparation. The overview of the PMAX neutron cross section library format was given as well as detailed analysis of FAXS library format developed at FER ZVNE. The calculation was performed for NPP Krsko cycle 27 depletion and main core design data were determined. In addition, using PARCS zero power model, point kinetics data needed for RELAP5 calculation were obtained. The possibility for addition of FER ZVNE changes to last available PARCS version 3.2 was analysed, and way to translate FAXS data to PMAXS format was proposed
