Flaw Distribution in Pressure Vessel Material (248)
Problem: Need estimates of fabrication flaw distribution in vessel material to support structure integrity modeling
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Integrated Systems
PNNL Solution:
- Obtain representative pressure vessel material for evaluation
- Perform laboratory ultrasonic evaluations to characterize flaws
- Validate ultrasonic data with complimentary NDE, SEM, metallography, and X-Ray Spectroscopy
- Flaw distribution data served as input to probabilistic fracture models
Capabilities Employed to Meet Client Needs: Ultrasonic inspection methods, test procedure development, embedded software (data acquisition, transmission, and storage, visualization, user interface), system integration, material science, statistical analysis data sets.
