Abstract:
The study of the issue of constructing a disposal facility for high-activity radioactive waste in the Republic of Belarus is associated with an assessment of the volume of radioactive waste to be deeply disposed of, generated as a result of the activation of structural materials of the VVER-1200 reactor of the Belarusian NPP. This paper presents the results of computational studies of the formation of solid high-level radioactive waste (HLW) and long-lived intermediate level radioactive waste (ILW-LL) during neutron activation of materials adjacent to the core of the VVER-1200 reactor structur

Abstract:
The significant impacts of burnable absorbers (UO2+Gd2O3) on reactivity, neutron multiplication factor (Keff), burnup, neutron flux distribution, power peaking factor, as well as safety criterions of the VVER-1200 reactor are discussed in this paper. Fuel economics have improved, resulting in increased enrichment of fuel & the need for better neutron flux distribution as well as reactivity controls. In order to achieve these enhancements in neutron flux distribution, burnable absorbers must be incorporated into the fuel matrix. To compute the 3D (three-dimensional) model for VVER-1200 fuel

Abstract:
The VVER-1000 thermal neutron reactor can operate on mixed uranium-plutonium fuel with a content of reactor-grade plutonium up to 5% with a 100% loaded core. In this case, plutonium burns up to 56% of odd isotopes. The energy potential of such plutonium is very low, and its further use in thermal reactors is impractical. However, such plutonium can be used in fast neutron reactors. The paper presents the results of investigating the possibility for such isotopic plutonium composition to be used in the BN-1200 thermal neutron reactor and its value be increased for the plutonium recycle in the r

Neutron irradiation damage is of the  most critical damagemechanisms in reactor vessel (RV) steel. Neutrons transfer theirkinetic energy to target atoms of RV steel that start to jumpcreating vacancies and interstitials known as Frenkel Pairs (FP).The FPs are responsible for formation of defected clusters andmicrostructural modifications. These effects deteriorate physicaland mechanical properties of the RV steels among  which results inlimiting the lifetime of reactor vessel.

Abstract:
Hydrogen production in severe nuclear accidents poses a significant threat to reactor safety, as exemplified by the Fukushima Daiichi disaster. This study investigates hydrogen generation in the VVER-1200 reactor under accident conditions, focusing on the zirconium-steam reaction responsible for hydrogen release in Zircaloy cladding. Using the SERPENT Monte Carlo simulation code, we model the reaction rates and hydrogen production volumes at elevated temperatures (1200°C), simulating a loss-of-coolant accident (LOCA). Results show substantial hydrogen production from the zirconium-steam reacti
