В статье рассмотрены различные концентрации выгорающего поглотителя (ПВ) гадолиния (Gd) в системе компенсации избыточной реактивности реактора типа ВВЭР при длительных кампаниях. Здесь проанализировано влияние метода на полномасштабную и полиячеечную модели размещения выгорающего поглотителя в топливе с гадолиниевыми стержнями (твэг). Показано сильное влияние состава выгорающего поглотителя (ПВ) в топливе с гадолиниевыми стержнями (твэг) на зависимость коэффициента выгорания топлива.

The paper considers various concentrations of burnable absorber (BA) Gadolinium (Gd) in the system of compensation of excess reactivity in the reactor of WWER type at the extended campaigns. It is analyzed the influence of the method for the Full-scale and Poly-cells model placing the burnable absorber in the fuel with gadolinium rods (tveg). The strong influence of the BAs composition in the fuel with gadolinium rods (tveg) dependence on the multiplication factor of the fuel burnup is shown.
