摘要

本文考虑了通过改变 VVER 燃料组件中含钆燃料元件的数量和燃料元件中的钆质量装载量来优化补偿过剩反应性的液体系统。利用简化的燃料加注模型，得出了反应堆临界状态下中子倍增因数与可燃吸收剂的理想关系，只使用可燃吸收剂即可保持临界状态。计算是使用 Serpent 中子物理程序代码 2.1.32 版（芬兰）进行的。据估计，在与理想方案类似的实际方案中，使用液体补偿系统所产生的未补偿反应性和低浓度液体放射性废物将大幅减少。

Use of burnable absorbers for reducing water exchange during the VVER liquid control

The paper considers the optimization of a liquid system for compensating excess reactivity by varying the number of gadolinium-containing fuel elements in a VVER fuel assembly and gadolinium mass loading into the fuel elements. Using a simplified refueling model, an ideal dependence of the neutron multiplication factor with burnable absorbers is obtained with reactor criticality, which is maintained using only burnable absorbers. The calculations were carried out using the Serpent neutron physics program code, version 2.1.32 (Finland). A significant reduction in uncompensated reactivity and low-level liquid radioactive waste generated using a liquid compensation system is estimated for real options similar to the ideal one.
