AbstractFracture toughness is a key parameter for evaluating the structural integrity of reactor pressure vessels (RPV). In this paper, fracture toughness K-Jc of different sized RPV specimens is tested at different temperatures. Master Curve method was used to model K-Jc and the ductile-brittle transition reference temperature T-0 is obtained. It is shown that the smaller the specimen size is, the lower the T-0 value is. The small specimen is not able to completely replace the standard 1CT specimen in the irradiation surveillance program to obtain T-0 and material toughness. J-Q theory is employed to study size effect and crack tip constraint effect on K-Jc. It is shown that Q (constraint) decreases as the specimen size decreases. A prediction model to transfer the reference temperature T-0 of different specimens is developed considering constraint effect by means of Q.
