Heat Transfer Mechanism and Thermal Sleeve Performance of Control Rod Drive Mechanism
摘要
Abstract
The control rod drive mechanism (CRDM ) relies on forced cooling measure to maintain its operating temperature .For the complex issue of CRDM heat transfer mech-anism ,the thermo-siphoning natural heat convection analysis model was established based on the hypothesis w hich divides coolant inside CRDM into hot side and cold side , meanw hile ,the experiment to measure CRDM inside/outside temperature distribution and total heat dissipating capacity under different conditions was conducted .Through comparison of analysis results and experimental data , the analysis model based on hypothesis can correctly simulate CRDM heat transfer in real situation , the thermo-siphoning heat and mass transfer is the major way of CRDM axial heat transfer ,and the use of thermal sleeve can weaken thermo-siphoning and reduce heat dissipating capacity effectively .关键词
