Westinghouse is best positioned to design and deliver customized services using resins, for various applications, on nuclear sites. Resins are highly adaptable to specific customer needs.
Westinghouse develops processes and toolings using resins, in combination with the Westinghouse expertise in NDE, robotics solutions and nuclear field services experience. Each development is customized, to take into account the specified customer requirements.
Resins can be used to perform replica molding, for detection and characterization of defects or for dimensional measurements. Westinghouse can deploy remote replica molding solutions in contaminated and confined environments (pipes, etc.).
Weld inspection by replica molding and microscope analysis
A resin coating can be sprayed on surfaces or equipment and is easily peeled:
Example of decontamination application
Resin seals can be applied on all types of surfaces and pieces to provide chemical protection and/or leak tightness.
Examples of resin sealings on horizontal and vertical elements
Resin coatings can be used as a permanent protection against corrosion, for example for components located outdoors and/or in a saline atmosphere.
Example of the efficiency of the protection against corrosion on identical black steel plates located outdoors.

Resin injection can successfully be used for debris retrieval, where conventional debris retrieval solutions (vacuuming, gripping tools, etc.) might not be efficient (long pipes with elbows, etc.).
Debris retrieval by resin injection
Resin can be used for leak detection, as well as for permanent leak repairs, for example on the stainless steel liner welds of nuclear pools.
