Abstract

The role of freely migrating point defects during neutron irradiation in the defect structure development with the presence of permanent sinks is studied using rate equations. Three specific cases are examined as a function of the distance from the surface: (1) only interstitial cluster existing system, (2) interstitial cluster and vacancy cluster coexisting system, and (3) only vacancy cluster existing system. The obtained results are as follows. In case (1): easy formation of interstitial clusters in thin specimen, and near the surface and the grain boundary of thick specimen; no clusters in the deeper region of thick specimen. In case (2): easy formation of interstitial clusters in thin specimen, and near the surface and the grain boundary of thick specimen just the same as those in case (1); the growth of both types of clusters in the deeper region of thick specimen. In case (3): easy formation of vacancy clusters near the surface of the specimen. These results are compared with the experimental results.
