| 31. | Control rods that are made of a neutron poison are used to absorb neutrons.
|
| 32. | The control rod channels are cooled by an independent water circuit and kept at.
|
| 33. | The remaining 20 positions are reserved to the control rods.
|
| 34. | Consequently, the reaction can be controlled with electromechanical control systems such as control rods.
|
| 35. | The boron in the control rods stopped the nuclear reaction.
|
| 36. | Moderator ejected during the Chernobyl disaster shows an intact control rod channel . ]]
|
| 37. | The vessel contains nuclear fuel and the control rod drive regulates the reactor's output.
|
| 38. | Numerous procedures were conducted to evaluate control rods to ensure they were operating properly.
|
| 39. | Twenty-one control rods were provided, long, across and thick.
|
| 40. | Either inserting the control rods or removing the heavy water moderator can stop the reaction.
