Abstract

Abstract

Based on the power supply timing sequences of control rod drive mechanism (CRDM), the action characteristics of stationary gripper in CPR1000 nuclear power unit and the test results in 10 units, the effect law of primary loop liquid fluid temperature, pressure and with or without CRDM on the opening time of the CRDM stationary gripper during unit commissioning start-up and normal operation is found, and based on this, the acceptance criteria range of CRDM stationary gripper opening time under different working conditions is optimized. The conclusion can not only be used as a reference for the acceptance criteria of CRDM stationary gripper opening time in the other units with the same type during commissioning start-up and normal operation, but also can be used as a reference for the analysis of the theoretical force model of the opening process of CRDM stationary gripper.
