Abstract | The article deals with the relevance of solving issues to improve the energy efficiency of the use of extracted hydrocarbon fuel, as well as the feasibility of developing and applying these measures in the economies of industrially developed countries. The necessity of having a permanent reliable source of electricity when using renewable and alternative sources of electricity is substantiated. As a permanent and reliable source of electricity, it is proposed to use operating and developing nuclear power plants. The use of these power plants requires the improvement of various systems for various purposes in them. To do this, the paper presents an analysis of the parameters of the steam and gas systems of pressure compensators to ensure the necessary pressure of the coolant in the first circuit of the nuclear power plant. Analysis of the parameters of operation of these systems is presented in tabular readable form. Based on the analysis, a "hybrid" pressure compensator system is proposed for detailed consideration, which includes the positive properties of the pressure compensator systems under consideration - steam and gas. An estimated calculation of the possible use of air (or gas) in the free volume of the pressure compensator with the provision of preliminary pressure is presented, followed by bringing the value of this pressure to the required value during operation. The advantages and disadvantages of the considered systems and some issues that require detailed study are noted. |
Keywords | nuclear power plant, pressure (volume) compensation system, steam pressure compensator system, gas pressure compensator system, initial pressure calculation, «hybrid» pressure compensator system. |

Abstract | The paper presents the results of a computational and theoretical analysis of the use of various burnable poisons placed in a fuel rod for the maximum reduction in the reactivity margin compensated by a liquid system based on a boron absorber for VVER-type reactors operating in extended campaigns. Various layouts of fuel rods placement in fuel assemblies and with different concentrations of burnable poisons are considered, which are considered natural gadolinium and erbium. The analysis is carried out using simplified models of fuel burnup at partial refueling. |
Keywords | Burnable absorber (BP), polycell, VVER, Serpent, multiplication factor (K∞), excess reactivity, gadolinium, fuel rod, erbium, boron regulation. |
