| DIMENSIONAL CHANGES IN GRAPHITE DURING HIGH-TEMPERATURE IRRADIATION IN THE HIGH FLUX REACTOR RCN, PETTEN. Project DRAGON. | |
| Blackstone, R.; Graham, L.W. | |
| 英文摘要 | The dimensional changes observed in a range of graphitic materials following irradiation at 600, 900, and 1200 deg C are reported. The results are discussed in the light of current models for irradiation damage in graphite and it is concluded that for conventional materials the dimensional behaviour can be related to the material properties. Further confirmation of the extreme dependence of the dimensional changes on the crystallite size has been obtained. The way in which the rate of dimensional change varies with temperature is compatible with this effect being caused by vacancy loss at crystallite boundaries. For a given crystallite size there appears to be a breakaway temperature above which the rate of dimensional change accelerates rapidly. (auth) |
