| 英文摘要 | Although the qualitative mechanism of irradiation damage and dimensional change of graphite crystallites is quite well understood, the existing quantitative theories do not predict the irradiation shrinkage behaviour of a range of graphites with very good accuracy. It is suggested that this is because the effects of crystallite height, crystallite diameter crystallite shape and crystallite mechanical properties such as the shear modulus are not considered with respect to the magnitude of crystallite/crystallite dimensional interactions. A model which takes into account these effects is developed and the associated physical property parameter correlated against the initial irradiation volume shrinkage rates of fourteen different graphites. It is considered more logical that the volume change of a graphite should be first understood and the anisotropy taken into account at a later stage. (auth) |
