Description

Delayed neutron parameters of fast zero-power VENUS-F reactor core configurations are determined with Monte Carlo calculations using various nuclear data libraries. Differences in the calculated effective delayed neutron fraction and the impact of the delayed neutron data (6- or 8-group precursors) that are applied in the experimental data analysis on the measured reactivity effects are studied. Considerable differences (up to 15%) are found due to the application of 235U and 238U delayed neutron data from JEFF, JENDL and ENDF evaluations. (authors)
