Definitions
- the present invention relates to a control rod drive upper shroud in which a four-channel control rod position transmitter is accommodated, and more particularly, to a control rod drive upper shroud in which a four-channel control rod position transmitter including a four-channel control rod position transmitter is increased.
- a control rod position transmitter (RSPT) is installed in each control rod upper shroud (1) so that the reed switch clamp (4) of the control rod position transmitter (5) operates when the permanent magnet on the control rod extension shaft moves. Generates output voltage proportional to the position of control rod and transmits position information of control rod.
- the control rod position transmitter 5 is installed at the top of the reactor by 2 channels on the 4 finger control rod. If the control rod position transmitter 5 fails, the control rod position transmitter 5 should be replaced after the reactor stops. .
- the circular top plate 2 on the upper shroud 1 is provided with two channel control rod position transmitters 5 on two paired Reed Switch Clamps 4. It is.
- the upper pressure housing 6 may vibrate and shake. If the earthquake load is large, the permanent magnet on the upper part of the control rod extension shaft may move and be spaced apart from the control rod position transmitter 5. In this case, the position transmission function of the control rod position transmitter 5 may be temporarily lost.
- the present invention was devised to solve the problems described above, in case the control rod position transmitter of the control rod position transmitter is stopped in case of an earthquake, such as a stable stationary earthquake, the control rod position transmitter is stopped.
- the purpose of the present invention is to provide an upper shroud of a control rod drive device in which a four-channel control rod position transmitter is configured to increase the control rod position transmitter to four channels.
- control rod drive device upper shroud accommodating the four-channel control rod position transmitter according to the present invention is provided with a protruding circular plate on the upper shroud, and four reed switch clamps are installed on the protruding circular plate.
- Four control rod position transmitters are installed on the reed switch clamp.
- the upper rod of the control rod drive device accommodating the four-channel control rod position transmitter according to the present invention has the following effects.
- the present invention can improve the power generation stop due to a channel failure according to the increase in the number of channels of the control rod position transmitter during an earthquake such as a safety stop, and the reliability of the position information transmission function of the control rod position transmitter is improved.
- the present invention can secure the space to accommodate the four-channel control rod position transmitter by improving the upper plate structure of the upper shroud to the protruding circular plate, and by changing the shape of the reed switch clamp due to the failure of the control rod position transmitter There is an advantage in minimizing the triggering of the reactor.
- FIG. 1 is an exemplary view showing a state in which a control rod drive upper shroud is installed in a conventional two-channel control rod position transmitter;
- Figure 2 is an exemplary view showing a state in which the control rod drive upper shroud is installed four channel control rod position transmitter according to the present invention.
- control rod position transmitter 6 upper pressure housing
- Figure 2 is an exemplary view showing a state in which the control rod drive upper shroud accommodated four-channel control rod position transmitter according to the present invention is installed.
- control rod drive device upper shroud accommodating the four-channel control rod position transmitter according to the present invention is provided with a protruding circular plate 3 on the upper shroud 1, the protruding circular plate 3
- Four reed switch clamps (4) are installed on the top, and four control rod position transmitters (5) are installed on the reed switch clamps (4).
- the reed switch clamp 4 has a hollow portion 7 formed at the center thereof, and at the same time, four reed switch clamps 4 are integrally formed with respect to the hollow portion 7.
- the control rod position transmitter 5 is configured to surround the upper pressure housing 6 therein.
- the control rod position transmitter 5 of the control rod position transmitter 5 becomes inoperable in the event of an earthquake such as a stable stationary earthquake.
- the upper shroud 1 is mountable on the reed switch clamp 4 in a four-channel control rod position transmitter 5, and the control rod position transmitter 5 surrounds the entire upper pressure housing 6. .
- the upper rod of the control rod driving device accommodating the four-channel control rod position transmitter according to the present invention having the structure as described above improves power generation stop due to a channel failure due to an increase in the number of channels of the control rod position transmitter 5 during an earthquake such as a safety stop. It is possible to improve the reliability of the position information transmission function of the control rod position transmitter (5).
