Simulating the behaviour of the fast reactor JOYO

    Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review


    The benchmark concerning the series of experiments performed for Japanese experimental fast reactor JOYO to determine its basic features was calculated with two Monte Carlo neutron transport codes: MCNP4C and PSG. The purpose of the work was to compare the performance of the two codes to each other and the simulations to the measurements. The calculation tasks were based on two different accuracy levels of the geometry description, the homogeneous and heterogeneous models. It was observed that the codes provided quite consistent results with each other. But when compared to the experimental results, the reliability of the simulations was varying. Especially small changes of the multiplication factor caused a great loss of accuracy.
