Рассматриваются различные схемы размещения выгорающего поглотителя в системе компенсации избыточной реактивности в реакторе типа ВВЭР при удлиненных кампаниях с целью снижения максимальной концентрации борного поглотителя. На основе по вариантной оптимизации анализируется влияние способа размещения выгорающего поглотителя в твэгах (гомогенное и гетерогенное) и количество размещаемого выгорающего поглотителя в них, на максимальную величину запаса реактивности, компенсируемую системой борного регулирования.

The paper considers various schemes of placement of the burnable absorbers (BAs) in the system of compensation of excess reactivity in the reactor of WWER type at the extended campaigns for the purpose of decrease in the maximum concentration of the boron absorber. On the basis of the variant optimization the influence of the method of placing the burnable absorber in the fuel rods (homogeneous and heterogeneous) and the amount of the placed burnable absorbers in them on the maximum value of the reactivity reserve compensated by the boron control system are analyzed
