| 1. | Scram of electromagnetic control rod drive mechanism with various flow velocities 不同流速下电磁驱动控制棒的落棒特性 |
| 2. | Behavior of hydraulic control rod drive systems for weightlessness or excess weight conditions 水力驱动控制棒的失重和超重工况运动特性 |
| 3. | 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 摘要应用计算流体力学程序cfx5对水力驱动控制棒步进缸内部的三维流场进行了计算和分析。 |
| 4. | Electrohydraulic push rod drives the two - way pump to output pressure oil with rotation of motor clockwise and counter - clockwise , by control of hydraulic valve , send to the hydraulic cylinder , to achieve the reciprocating movement of the piston rod 电液推杆以电动机正反转,带动双向泵输出压力油,经液压阀控制,送至液压缸,实现活塞杆的往复运动。 |
| 5. | 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 在需要紧急停堆时, ?须切断控制棒驱动机械的电源,控制棒便会因地心吸力而快速下坠至反应堆堆芯,立即停止核裂变。 |
| 6. | 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 及控制反应堆的核裂变,部份燃料组件装配有控制棒,控制棒组件由星型架及多根含银( ag ) 、铟( in )和镉( cd )的中子吸收体棒所组成,因此移动控制棒的上下位置就可以控制反应堆内中子的数目与及核裂变。 |
| 7. | 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 及控制反应堆的核裂变,部份燃料组件装配有控制棒,控制棒组件由星型架及多根含银ag铟in和镉cd的中子吸收体棒所组成,因此移动控制棒的上下位置就可以控制反应堆内中子的数目与及核裂变。 |
