Comparison of Zr-2.5Nb pressure tube fracture toughness and CCL using small-CT and large burst specimen
- 1. Korea Atomic Energy Research Institute, Taejon (Korea, Republic of)
Description
By using non-irradiated materials (quad- and double-melted) which had the same composition as irradiated materials of Zr-2.5Nb pressure tube (O-08, M-11) from the first domestic CANDU power reactor, Wolsung I the comparison analysis was carried out on the result derived from experiment of fracture toughness of the large and small specimen. The result showed that non-irradiated CCL had a tendency of decrease with temperature, while CCL of O-08 irradiated large sample maintained constant at room temperature and 250 deg. C. CCL of O-18 irradiated small sample showed higher tendency than that of M-11. Especially, in O-18 irradiated materials small specimen at room temperature had a tendency of more conservative than larger specimen. But at 250 deg. C the relative conservativeness in smaller specimen disappeared. (Hong, J. S.)
