A new method is proposed to predict the irradiation induced property changes in nuclear; graphite, including the effect of a change in irradiation temperature. The currently used method; to account for changes in irradiation temperature, the scaled fluence method, is demonstrated.; The proposed method, which makes use of evolution equations to describe the rate of change; of the property of interest, is described in detail. The property value is obtained by integrating; the evolution equation. A sudden change in irradiation temperature instantaneously affects the; rate of change, but the property value itself remains continuous. Numerical examples are used; to demonstrate the increased accuracy of the proposed method.
