西安脉冲堆额定功率运行考验和氙毒测量

Operation Trial at Rated Power and Measurement of Xenon Poison on Xi'an Pulsed Reactor

介绍了西安脉冲反应堆(XAPR)稳态堆芯2MW额定功率72h连续运行考验的概况,给出了额定满功率运行条件下,堆厂房环境辐射剂量水平、平衡氙毒和碘坑反应性深度等测量结果。试验表明,XAPR本体及各工艺系统运行正常,综合性能达到设计要求,且芯体温度有较大的热工安全裕度。

The article introduces the general situation of 72 hours continuous operation trial at rated power on Xi'an Pulsed Reactor(XAPR) steady-state core. The experimental results of environmental irradiation dose testing, measurement of equilibrium xenon poison and iodine pit reactivity depth while operating at rated full power are also given. The experimental results show that the main body and process systems of XAPR are working orderly, and that the synthetic performance has reached the design requirements, and that the fuel temperature has more safety margin.
