Abstract

Abstract

The Control Rod Drive Mechanism (CRDM) in nuclear reactor operates in the harsh environment of high temperature, high pressure, and high radiation for a long time. In order to effectively prevent the damage caused by excessive temperature, it is necessary to predict and estimate the temperature of internal components of CRDM to improve the safety and reliability of nuclear reactor. This paper proposes a temperature estimation method based on the equivalent thermal network method. First, the heat source parameters required for the temperature rise analysis are calculated. Then, the thermal resistances in different regions are solved to construct an equivalent thermal network model of the CRDM, enabling rapid and accurate estimation of the CRDM temperature. Finally, the results are validated using Finite Element Analysis (FEA). The validation results show that the proposed CRDM temperature estimation method has high accuracy, providing a theoretical basis for subsequent novel structural design and reliability analysis.
