Scram of electromagnetic control rod drive mechanism with various flow velocities 不同流速下電磁驅(qū)動控制棒的落棒特性
Behavior of hydraulic control rod drive systems for weightlessness or excess weight conditions 水力驅(qū)動控制棒的失重和超重工況運動特性
The three dimensional flow field of the step cylinder in hydraulic control rod driving system ( hcrds ) is calculated and analyzed with the computational fluid dynamics program cfx5 in detail 摘要應(yīng)用計算流體力學(xué)程序cfx5對水力驅(qū)動控制棒步進缸內(nèi)部的三維流場進行了計算和分析。
The reactor can be shutdown during emergency by cutting off the power supply to the control rod driving mechanism which then causes the control rods to drop down to the reactor core by gravity quickly and thereby stopping the nuclear fission immediately 在需要緊急停堆時, ?須切斷控制棒驅(qū)動機械的電源,控制棒便會因地心吸力而快速下墜至反應(yīng)堆堆芯,立即停止核裂變。
Each control rod assembly consists of a number of absorber rods attached to a spider assembly and coupled to the control rod drive mechanism . the absorber rods are made up of neutron absorbers such as silver , indium and cadmium . hence , by adjusting the position of the control rods , the number of neutrons and thus the fission rate in the reactor can be controlled 及控制反應(yīng)堆的核裂變,部份燃料組件裝配有控制棒,控制棒組件由星型架及多根含銀( ag ) 、銦( in )和鎘( cd )的中子吸收體棒所組成,因此移動控制棒的上下位置就可以控制反應(yīng)堆內(nèi)中子的數(shù)目與及核裂變。
And allow control of the fission rate inside the reactor , some fuel assemblies are fitted with control rods . each control rod assembly consists of a number of absorber rods attached to a spider assembly and coupled to the control rod drive mechanism . the absorber rods are made up of neutron absorbers such as silver , indium and cadmium 及控制反應(yīng)堆的核裂變,部份燃料組件裝配有控制棒,控制棒組件由星型架及多根含銀ag銦in和鎘cd的中子吸收體棒所組成,因此移動控制棒的上下位置就可以控制反應(yīng)堆內(nèi)中子的數(shù)目與及核裂變。
