38 NuclearPlantJournal.com Nuclear Plant Journal, May-June 2019 Dominion Energy Surry Power Station, Structural Technologies, and Simpson Gumpertz & Heger present an innovative, First-of-a-Kind (FOAK) upgrade of Safety-Related (S-R) piping systems using Carbon Fiber-Reinforced Polymer (CFRP). The project was successfully completed during the Spring 2018 Refueling Outage (RFO) at Surry Unit 1, and more repair phases are scheduled through 2025. The nstallation of CFRP provides a fully structural upgrade to critical, large diameter S-R piping systems, delivering long term benefits including a significant reduction in safety and operational risks, along with maintenance costs. This FOAK Project aligns with the Nuclear Promise ® by implementing an innovative solution to enhance reactor safety, operational efficiency and overall reliability. HawkEye HD™ Award Type: NEI TIP Award. Company: PSEG Nuclear, Hope Creek Generating Station, Framatome Inc. Team: Adam Burke, Sean Lund, Daniel Mostashari, Tony Oliveri, Michael Reed and Adam Zulauf, PSEG Nuclear. Framatome, in collaboration with PSEG, recognized the potential at Hope Creekforanautomatedvisualexamination tool to provide a versatile, high quality, efficient and most importantly, safer product. The vision of this tool came to realization with Framatome’s deployment of HawkEye HD™, the first-of–a-kind fully automated tool to provide remarkable cleaning capabilities and deliver High Definition (HD) video from a platform designed to operate in the harsh environment of a nuclear reactor vessel. A distinct advantage of HawkEye HD’s robust design is its ability to offer exceptionally stable HD images throughout the vessel including those areas where the high-flow rates of Shut Down Cooling prohibited conventional examination methods. Not only has the tool reduced exam time, but its versatility has minimized employee exposure to both radiological and industrial hazards by replacing the need to deploy multiple exam teams into the inspection platform installed under the Refueling Bridge. Ultrasonic Testing of Pre-Stressed Concrete Embedded Cylinder Pipe (PCCP) Award Type: NEI TIP Award. Company: STP Nuclear Operating Company. Team: Rick Stark, Lyle Spiess, Rob Frazee, Craig Younger, Brian Migl, STP Nuclear Operating Company. The STP project team, working together with NDT Corporation, developed and implemented a plan to perform a thorough assessment of STP’s Circulating Water (CW) Pipelines using ultrasonic testing. A low frequency stress wave was generated in the concrete pipe, then the ultra-sonic responses are collected and evaluated. Data was reviewed and anomalous pipe data is sent to a Subject Matter Expert (SME) for a structural assessment, finite element analysis (FEA), of the pipe relative to its design specification. A factor of safety is generated from the FEA. The use of this technology allowed engineers to understand the present condition of the pipe structurally, prioritize and schedule rehabilitation accordingly. This process, known as Shear Wave UT Testing, has afforded STP the ability to effectively identify, monitor and trend very complex and costly repairs on critical station infrastructure. 3D Printed Parts/Prototype Initiative Award Type: NEI TIP Award. Company: Talen Energy, Susquehanna Steam Electric Station. Team: Russell Karshick, Darryl Schwarz, Dustin Wertheimer, Erin Kovach and Manu Sivaraman, Talen Energy. Talen Energy’s Procurement Organization has taken an innovative approach to procuring obsolete parts by utilizing 3D printing/ scanning 2019 TIP... ( Continued from page 37)
