LOCKING RING AND METHOD OF SECURING THE NUT OF A CONTROL ROD DRIVE HOUSING OF A NUCLEAR POWER PLANT |
摘要 |
A locking ring holds a control rod drive housing tube of a nuclear power plant when a pressure chamber having a contact wall is pressurized. The contact wall faces the control rod drive housing tube presses against it when the pressure chamber is pressurized. The locking ring can lock a threaded nut after it has been screwed onto the control rod drive housing tube. In a method for securing a threaded nut of a control rod drive housing tube of a nuclear power plant in the vicinity of the threaded nut, a body is attached to the control rod drive housing tube, as a result of a contact surface of the body engaging the control rod drive housing tube. A contact surface of the pressure chamber is pressed onto the control rod drive housing tube when the pressure chamber is pressurized. |
