<p>PROBLEM TO BE SOLVED: To shorten the maintenance time of a control device by performing the investigation of cause and the support of repair from a remote place other than a plant when the control device or the like within the plant fails. SOLUTION: A data collection device 120 collects each signal in an alarm generation such as dip pipe control device alarm output signal (i), recirculating flow control device alarm output signal (h), failure display signal (j), dip pipe control failure display signal (k) or the like in the data collection part of the device 120. This system has a means for setting the device 120 for inputting the maintenance information related to a control device where a failure has occurred to the power plant side on the spot and transmitting the maintenance information to a maintenance center or the like in a remote place, and a means for setting a data transmitter-receiver 121 for receiving and displaying the maintenance information from the power plant to the remote place side. The device 120 receives the maintenance information and alarm output signal from each control device including the control device set within the management area of a nuclear power plant and selectively transmits the maintenance information where the alarm is issued to the remote place.</p> |
