Westinghouse is known as a global industry expert in decontamination processes, based on its proven abilities in past and ongoing decontamination work.
The company has an exceptionally skilled resource base and continues to build on that skill set through relationships with expert groups and research organizations.
Chemical decontamination was developed for commercial use in the late 1970s and early 1980s and has been used by Westinghouse for more than 20 years. It can be defined as the use of chemical reagents to remove radioactivity containing corrosion products from the internal surfaces of piping and equipment.
Westinghouse’s expertise in Canada complements and enhances our global decontamination capabilities such as the application of chemical reagents to remove radioactive corrosion products from the pressure boundary surfaces of piping and components. The intent of the process is to minimize exposure to workers by removing radioactive impurities trapped in a thin surface oxide layer by first dissolving the oxide layer and then concentrating the impurities through filtration and ion exchange.
Westinghouse specializes in a variety of applications ranging from individual component to full system decontaminations, and offers the following benefits:
- Significant reduction in personnel and site radiation exposure
- Reduction in radwaste volumes and costs using the Electric Power Research Institute DFDX process
- Free release of materials
- Improved productivity
- Improved conditions and schedules for facility decommissioning
