摘　　要：利用研制的铀丰度在线监测装置对铀浓缩厂工艺管道中精料和贫料铀丰度进行在线监测,同时利用孔板流量计在线监测浓缩厂精料端工艺管线UF_6精料流量,然后利用分离功率方程计算得到分离功率。现场实验表明:在均不考虑物料损耗情况下,分离功率在线监测结果与铀浓缩厂分离功率申报值的相对偏差小于2.0%。A separative power on-line monitor system at gas centrifuge enrichment plant was developed including two 235 U enrichment monitors and one uranium hexafluoride flow-meter,and a set of corresponding software was developed.The enrichment of UF6 flowing through the processing pipes in uranium enrichment plant was measured by enrichment monitors.The UF6 gas flow rate in production pipes was measured by the orifice flow-meter.Finally,the separative power was calculated by 235 U enrichment and UF6 gas flow rate in the pipes.The results show that the maximum relative standard deviation between monitoring result and declaration value is less than 2.0%.
