The Perry Nuclear Power Plant (PNPP) experienced a catastrophic failure in their pressurized service water piping system resulting in an emergency shutdown and a two month outage. After careful inspection, evaluation, and selective repair and replacement of the fiberglass reinforced plastic (FRP) pipe, the cooling water system was returned to service. A permanent solution, however, was needed to structurally rehabilitate the pressurized piping system, and extend the operating life of the system, with the least amount of disruption to the daily operations of the plant. After evaluating various alternatives to resolve the problem, the Perry engineers choose Insituform East, Inc. (IEI) based on best value procurement practices. The project would require the development of a new cured in place (CIP) reinforced pressure product by Insituform Technologies to meet the structural and operating parameters specified by the customer. Additionally, the project presented unique planning, scheduling, and installation challenges all required to be performed in an industrial type setting with strict safety, quality, environmental, and security standards.
