摘要:
板状压水堆在长寿期反应堆中具有较好的应用前景。针对长寿期板状压水堆的需要,对中子学性能较好的4种可燃毒物:^(157)Gd_(2)O_(3)、^(167)Er_(2)O_(3)、^(231)Pa_(2)O_(3)和PACS-J开展可燃毒物装载形式选型研究,筛选出中子学性能较优的装载形式。研究结论为:针对不同可燃毒物采用不同装载形式,可以更好地满足长寿期板状压水堆的综合要求;对于中子学性能较优的可燃毒物,^(157)Gd_(2)O_(3)和^(167)Er_(2)O_(3)可采用可燃毒物与燃料均匀混合的装载形式;^(231)Pa_(2)O_(3)可采用包壳中掺杂可燃毒物的装载形式;PACS-J可采用可燃毒物以颗粒形式与燃料混合的装载形式。
摘要(英文):
Plate-shaped PWRs have good application prospects in long-life reactors. According to the needs of long-life plate-shaped PWRs, the four burnable poisons with better neutronics performance (157Gd2O3, 167Er2O3, 231Pa2O3 and PACS-J) were studied on the selection of burnable poison loading forms, and the loading form with better neutronics performance was screened out. The results show that: Different loading forms for different burnable poisons can better meet the comprehensive requirements of long-life plate-shaped PWRs; For burnable poison with...
