1. It activated an automatic safety system, sending control rods down into the core of the plant.

2. Connected with it is a control rod.

3. Horizontal Stabilizer, Tab Control Rod Fairing, 334PT.

4. Horizontal Stabilizer, Tab Control Rod Fairing, 344PT.

5. They consist of two switches and a control rod with two moveable collars.

6. The cross sections in the region that includes control rod and part reflector are homogenized by the weight of fluxes.

7. Electromagnetic movable coil control rod drive mechanism is a new type drive mechanism.

8. Their power was also increased by introducing a control rod which moved up and down with the beam .

9. The control rod is inserted into the containing via hole from top to bottom, and the lower end of the control rod supports against on the fusible body.

10. The relationship between the height of the control rod bank and excess reactivity was studied and explained.

11. To measure the calibrating curve of control rod more speedily.

12. This paper describes a kind of control rod position indication system with self-coding detector.

13. The cruciform control rod controlling is the main method to control reactivity in the nuclear heating reactor (NHR).

14. The control rod drive mechanism(CRDM) is one of the key equipment related to reactor normal operation, safety and reliability.

15. The hydraulic system of control rod drives is one of the key systems in a nuclear heating reactor. The unplanned outage will be directly caused by the system failure.
