Study on Reactor Coolant Temperature Channel Calibration Test in Digital Control Nuclear Power Plants

The paper introduces the content of the TP RCP63 test simply, and analyzes the effect on the test due to the abroad application of digital control systems. Furthermore, the paper emphasizes the study of the difference and corresponding problems in the test comparing with the nuclear power plants with the analogue technology. As to the problems, the corresponding design solution are provided for the temperature difference, the coefficient of average temperature summer and the temperature signals calibration in TP RCP63 test of the digital nuclear power plants.
