启明星Ⅱ号双堆芯零功率装置

Venus-Ⅱ Dual-core Zero Power Reactor

启明星Ⅱ号是针对我国新型先进核能系统基础性研发及工程化设计验证而研制的双堆芯零功率装置。启明星Ⅱ号拥有两个堆芯,水堆堆芯侧重于开展热中子能谱环境下的原理性验证实验研究,铅堆堆芯侧重于重金属冷却的快中子反应堆及加速器驱动的次临界系统(ADS)等先进核能系统的中子物理特性实验研究。启明星Ⅱ号通过一套仪控系统实现了两个堆芯的集成化控制和测量数据采集,每个堆芯均配备了多套非能动安全停堆系统,固有安全性强。在启明星Ⅱ号上获取了多种堆芯的基准性临界实验数据,可为我国轻水堆的技术创新、重金属冷却反应堆工程化设计及新型核能系统的集成研发提供支持。

Venus-Ⅱ is a dual-core zero power reactor aiming on the fundamental research and engineering design validation of new advanced nuclear energy systems in China.Venus-Ⅱ has two cores,the water core mainly focuses on principle validating experimental research in thermal neutron environment,while the lead core building the special material and neutron energy environments for lead based reactor,focuses on neutron physics characteristic experimental research for advanced nuclear energy systems such as heavy metal coolant reactor and accelerator-driven subcritical system (ADS).Two cores in Venus-Ⅱ are controlled and measured by one instrument and control system,and each core has multiply passive safety shut-down systems leading to high inherent safety.Multiply series of benchmark critical experiment results were obtained from Venus-Ⅱ,which will support the fundamental research and engineering design validation of new advanced nuclear energy systems in China.
