Summary
Many models have been proposed to explain and predict in-pile creep of cladding materials. Our purpose is to consider the relative merits of models based on diffusion of irradiation-induced point defects and to apply those models to zirconium-base alloys. At intermediate stresses, creep is believed to be due to dislocation glide between irradiation-produced obstacles and controlled by climb over those obstacles. The two primary models to predict dislocation climb are based on (1) the alleged increased attraction dislocations have for interstitials over vacancies and (2) statistical fluctuations in the arrival rate of vacancies and interstitials produced in equal numbers. Both models are considered in detail. In addition to creep caused by edge dislocation glide and climb, creep due to preferred nucleation of dislocation loops and their subsequent growth is considered. Such creep is believed to be dominant at low stresses.
