Understanding BWXT's Failure Analysis Labs
BWXT Technologies, Inc.'s Failure Analysis Laboratory (FAL) is a state-of-the-art facility equipped with cutting-edge digital photography and metallurgical instruments aimed at supporting comprehensive failure analysis investigations. The FAL is staffed by a team of highly experienced engineers and technicians proficient in various failure analysis techniques such as microstructural characterization of metals, fractography, corrosion processes, welding metallurgy, and mechanical testing.
Key Projects and Expertise
Projects undertaken at the FAL typically involve identifying the root cause of damage or failure in components, recommending corrective measures to prevent reoccurrence, resolving material-related issues in manufacturing processes, pinpointing environmental impurities contributing to material degradation, and evaluating materials for compliance with specifications. The FAL's expertise primarily lies in radioactive components from pressurized water reactors and boiling water reactors, but they also handle non-radioactive samples. Recent projects include reactor vessel head degradation, instrumentation nozzle leaks, tube cracking, steam generator failures, filter debris analysis, and investigations into cracking in various components like springs, weldments, and valve hardware. The FAL is well-versed in a range of alloy systems used in nuclear facilities, including zirconium alloys, inconel alloys, stellite alloys, and stainless, carbon, and alloy steels.
Comprehensive Services Offered
The FAL provides a comprehensive array of metallurgical and failure analysis services for radioactive components taken out of service. These services include visual and stereovisual examinations, X-ray radiography, dimensional inspection, liquid penetrant inspection, machining and sectioning, Rockwell and microhardness testing, X-ray diffraction, microstructural examination, and scanning electron microscopy.
