Description

The pressure tubes of Wolsong-1 are made of cold-worked Zr-2.5%Nb. The operating temperature is about 260 .deg. C ∼ 310 .deg. C and neutron flux level at full power is about 3 x 10 17 n/m2s, which causes thermal creep, irradiation creep and irradiation growth. The creep and the growth result in the longitudinal elongation and diametral expansion of the pressure tubes, which have their design limit, respectively. The Wolsong-1 pressure tubes were confirmed by the inservice inspection that the longitudinal elongation and diametral expansion has been progressed. This paper shows the lifetime evaluation for Wolsong-1 pressure tubes against diameteral expansion due to creep and growth
