摘要：
Internal diameter measurements have been carried out on pressure tube S-07 of KAPS II and fifteen RAPS II pressure tubes. These data have been analyzed to derive empirical correlation for predicting diameter change in pressure tube during irradiation. The correlations are derived for the diametral strain rates in terms of the stress, temperature and fluence for KAPS II and RAPS II pressure tubes which indicated essentially same functional dependences with a slight change in the prefactor (8.55 vs 12.35). This paper presents the details of the study carried out on modeling of diametral creep in the pressure tubes.
