“…The results of calculating the burnup of fuel assemblies with gadolinium for VVER-440 and VVER-1000 reactors are also presented in (Lötsch 2014, Novak et al 2017, Vnukov et al 2020. The burnup calculations for a VVER-1200 hexagonal fuel assembly (Abu Sondos et al 2019, Vnukov et al 2021) based on the Serpent code give sufficiently accurate results compared to the results obtained using other proven codes. Thus, the burnup calculations using the Serpent code lead to reasonable and sufficiently accurate characteristics of fuel assemblies, which makes the choice of software relevant (Stroganov et al 2014).…”

This article presents the results of neutronic calculations of a VVER-1200 fuel assembly carried out using the multi-purpose three-dimensional continuous-energy Monte Carlo particle transport code Serpent 2. The study compares neutronic characteristics during the fuel burnup process (1) with and (2) without fuel cooling. In the first option, the FA fuel campaign was simulated with 30-day cooling periods between reactor campaigns. The second option assumed simulating the FA fuel campaign without fuel cooling. In the course of the study, the authors determined the infinite neutron multiplication factors as well as the fuel burnup dependence of the concentrations of xenon, samarium and gadolinium nuclides. In addition, it should be noted that no differences were found in the change in the concentration of gadolinium isotopes, the discrepancy in the values of the multiplication factor, and the accumulation of samarium isotopes during the campaign.

Researches are done to improve parameters of nuclear reactors and reduce the cost of generated electricity directed towards determining of the most rational fuel usage. Different methods use different mathematical and physical models that results in some differences in received data. One of the methods is profiling of Nuclear Energy Reactors. In this paper the theory that is used in modeling and tallies in Serpent 2 is given, the methods of axial profiling of reactors are shown, comparison of received data and justification of their validity on intermediate state of the research are examined.
