Abstract

Abstract

In this paper, a specific irradiation device in the High Flux Engineering Test Reactor (HFETR) is studied and analyzed. The Monte Carlo code is used to describe the heat release of different materials at different axial heights. The thermal model is established by using the code STAR-CCM+, and the accuracy of the model is verified by the measured data. Under given conditions, the deviation between the calculated temperature of thermocouple measuring point and the measured value is 2.3%. It is found that the temperature measurement deviation of 1%-4% may be caused in the process of low temperature differential flow heat transfer by changing the number and arrangement of thermocouples without considering the radial and axial position changes of the short tube of the plug assembly of the irradiation device. In this paper, the measurement deviation of low temperature difference flow heat transfer process in irradiation device is revealed, which can provide a key reference for improving the accuracy of temperature measurement and the safe operation and engineering design of HFETR.
