摘要
本文针对紧凑型压水堆提出了一种可代替固体控制棒束的反应性控制方法—"液态金属控制",该控制方法不仅可以避免固体控制棒因机械传动带来的诸多技术问题、大幅简化堆芯结构设计,而且还具有布置灵活、反应性控制能力强等特点。计算结果表明:对于热功率为180MW、平均功率密度为91.2MW/m3的紧凑型压水堆,堆芯寿期可以达到1 000EFPD。
A new reactivity control method for compact PWRs-"Liquid Metal Control" has been proposed in this paper, which can be instead of the conventional control rod bundles. This method can entirely avoid these technical issues caused by the control rod mechanically-driven, and simplify the core structural design. The liquid metal reactivity control system can be deployed flexibly and control much more excess reactivity. For the compact PWR with the rated thermal power of 180 MWt and average power density of 91.2 MW/m^3 , the core lifetime can be achieved to 1 000 EFPD.
