[en] The three distinct radiation-induced dimensional changes, radiation growth, void swelling, and radiation-enhanced creep, are closely related to the precipitation of the radiation-produced vacancies and interstitials on sinks, such as dislocations, voids, and grain boundaries. The void-formation phenomenon has demonstrated a preferential precipitation of interstitials on dislocations. This precipitation of excess interstitials causes a volume expansion if the corresponding number of vacancies precipitates as voids. However, if the vacancies precipitate on two-dimensional sinks such as grain boundaries, radiation growth will occur provided the distribution of dislocations and/or of grain-boundary orientations is anisotropic. Excess precipitation of interstitials on dislocations causes them to climb and, hence, may accelerate climb-controlled creep. Relations are derived between the rates of excess precipitation of interstitials on various types of sinks and the rates of anisotropic swelling, and radiation-enhanced creep. It is shown that growth and creep can occur in both the presence and absence of voids. If the dominant defect sinks are voids and dislocations, the uniaxial growth rate and the creep rate become proportional to the swelling rate. (author)
