UO2/BeO interfacial thermal resistance (ITR) is calculated by diffuse mismatch model (DMM), and the effects of ITR on UO2-BeO thermal conductivity are investigated. DMM can predict UO2/dispersed-BeO ITR within the accuracy of orders of magnitude. However, UO2/continuous-BeO ITR is three to four orders of magnitude ... than DMM predictions. This indicates that UO2/dispersed-BeO ITR is mainly induced by the vibrational mismatch, while UO2/continuous-BeO ITR may be attributed to the contact resistance.
