The use of composites and synthetic materials is growing rapidly in structural and civil engineering applications. In particular, composites have proven invaluable in repairing existing infrastructure. The commercial industry has used products such as carbon fiber reinforced polymer (CFRP) and sprayed in place pipe (SIPP) to repair pipelines for over two decades. More recently, the nuclear industry has begun exploring composite repair for its aging nuclear infrastructure. Specifically, the industry is pursing the use of CFRP to repair safety-related piping.

This presentation will provide an overview of the design, testing, installation, and inspection of CFRP in safety-related piping in nuclear power plants. We will not only discuss how engineers work with CFRP, but also how the industry is working to update codes and regulations around the relatively new material.
