This work was conducted in order to validate the flaw evaluation criteria for class 2, 3, and balance of plant piping in nuclear power plants. A methodology was developed as part of the Battelle Integrity of Nuclear Piping (BINP) program for predicting fracture initiation transition temperature (FITT) for a surface crack in a pipe from the 85% shear area transition temperature from Charpy specimen data. The predictive relationship is described in a separate paper in this conference [1]. In order to validate this methodology a series of Charpy, dynamic tear test (DTT), compact (tension) (CT), single-edge-notch [tension] (SEN(T)), and full-scale circumferential surface-cracked pipe experiments were conducted at different temperatures. As part of this paper, the results from these tests, along with their potential impact on the validation procedure to predict the quasi-static brittle-to-ductile FITT will be discussed.
