This technology innovation improves nuclear safety, radiological safety, equipment reliability, labor efficiency and monitoring data quantity/quality at a significant cost savings over traditional handheld or retrofit vibration monitoring options. Volumetric Inspections of Inaccessible Piping via Robotic Crawler Award Type: NEI TIP Award. Company: Dominion Energy, North Anna Power Station. Team: Chris Allmond, Roger Galbraith, Ed Appel, Austin Bauer, Lauren Hembree, Aaron Huber, Jonny Minder, Berny Smith, Chris Wray. The Dominion Energy team tasked with inspecting auxiliary service water (ASW) piping at North Anna Power Station applied an innovative approach to determine the health of certain sections of buried piping. The approach used a robotic crawler to conduct ultrasonic examination inside critical, but uniquely configured, sections of the pipe. These line segments are a pipe-in-pipe configuration. Because these ASW line portions are sleeved, conventional excavation and ultrasonic testing cannot be completed to assure wall thickness meets minimum ASME Code compliance. By using the robotic crawler, the inspection of the ASW piping sections eliminated any human occupancy of the piping while yielding a complete volumetric examination; its use also reduced a cost of up to $3 million, including excavation, to less than $200,000. Control RoomGlasstop Simulator Award Type: NEI TIP Award. Company: Duke Energy Corporation, H.B. Robinson Nuclear Plant. Team: Dilip Sunthankar, Daniel Bacon, Terry Giese, Saeed Khalfay, Bryan Waldsmith. Duke Energy’s H.B. Robinson Nuclear Plant Simulator Group was instrumental in bringing to fruition their innovative vision of a full-scale Control Room Glasstop Simulator (CRGTS). The CRGTS is a replica of the Training Simulator in terms of form, shape, size and function; however, it was built at a fraction of the cost of the Training Simulator. The CRGTS uses the same simulation models and therefore provides dynamic responses that are identical to the Training Simulator. The CRGTS essentially provides a second simulator for the Robinson plant at a fraction of the cost of a conventional hard panel simulator. Digital Plant Viewer with Electronic Survey Award Type: NEI TIP Award. Company: Exelon Nuclear. Team: Brian Carroll, Kevin Burroughs, Eric Cota, Cliff Gray, Robert Holleran, Kim King, Chris Ledwich. Exelon’s Digital Plant Viewer is projected to save the organization $5million per year starting in 2019. It combines a variety of plant resources into an online interface including maps, plant data, video, virtual tours and electronic surveys. The system is available on desktop computers, on touchscreen kiosks and mobile devices in the Exelon Store. Plant maps have been used in combination with the Virtual Tours to provide orientation to personnel who are new to a site. Using the live video feeds to check status of work, supervisors and work crews have optimized their performance through better coordination. Electronic surveys are accessible through the Digital Plant Viewer and allow the user to perform timely self-briefs in the field without needing to consult RP for routine low risk work.
