Understanding Degradation Challenges
BWX Technologies, Inc. (BWXT) specializes in addressing the degradation of steam generator and heat exchanger tubing, caused by both mechanical and corrosion factors. This degradation has led to widespread repairs and replacements globally, impacting the reliability of power stations. The diverse range of degradation modes poses a significant challenge to the integrity of tubing, underscoring the importance of thorough inspections and monitoring for timely detection and characterization of issues to ensure tube integrity.
Advanced Probe Technology
BWXT employs a variety of cutting-edge probes designed for the detection, characterization, and sizing of indications in steam generator and heat exchanger tubing. Among these probes is the bobbin probe, primarily utilized for volumetric indications like pitting and fretting, and the X-probe, a transmit/receive array probe used to detect axial or circumferential indications as well as volumetric indications. The organization utilizes three types of X-probes, including a specialized tight-radius X-probe specifically engineered to navigate low row tubes with tight bends.
Sophisticated Analysis Techniques
Leveraging the latest available technology, BWXT conducts precise location, evaluation, and sizing of indications in steam generator and heat exchanger tubing. Highly skilled primary and secondary production and resolution analysts are employed for accurate data analysis. The analysis software utilized by BWXT offers multiple display modes, process channels, and multi-frequency mixes to determine essential parameters such as amplitude, phase, location, type of indication, and more.
Comprehensive Inspection Services
In addition to probe technology and analysis, BWXT provides a range of comprehensive inspection services including Eddy Current Inspection, CANDU PHWR Steam Generator Tube Prima® Inspection and Repair, Sludge Lancing, and Remote Visual Inspection. These services are essential for ensuring the safety, reliability, and efficiency of steam generators and heat exchangers in nuclear facilities.
