Nuclear Power Plant Component Fractures

Engineering analyses were performed on the intergranular stress corrosion cracking (IGSCC) of the thermal sleeves and “safe ends” in a Boiler Water Reactor (BWR) type of nuclear power plant.

In this project, a detailed evaluation was performed on the propensity for IGSCC to occur in Inconel 600 components in nuclear power plants (Boiling Water Reactors). These particular components, the thermal sleeve and safe end, had shown significant cracking at other plants prior to startup. Plant management decided to remove and replace the components prior to startup. Intertek performed a historical document review to establish the necessity for such action and evaluated the likelihood of IGSCC in existing and alternate materials. Intertek also provided deposition and trial testimony for this project.
