Utilization of PARCS/Serpent in small-scale reactor – Multiplication factor, rod worth, and transient

Popis výsledku v původním jazyce

Macroscopic cross-sections are generated by stochastic code Serpent (version 2.1.30) with ENDF/B-VIII.0 library and with a high emphasis on a wide range of utilization and reproducibility. Published cross-section generation approaches are used for analyses of 7 highly distinctive core configurations. This allows to asses their performance in a wider range than other papers aiming only at one specific core configuration. Even though predictions of a critical state are not sufficiently accurate for any actual usage (in case of the VR-1 reactor), calculated absorption rod worths reach a high potential for a fast and precise evaluation of safety criteria. Core kinetics parameters generated by Serpent with ENDF/B-VIII.0 library (for all three methods: Meulekamp, Nauchi, IFP) show a continuous underestimation of calculated power in all investigated transients during an insertion of a negative reactivity.
