The outage team pulled the core barrel and several new techniques were implemented to shield personnel from the increased radiation. Control Element Drive Mechanism High Temperature Coil Design Award Type: Westinghouse Combustion Engineering TIP Vendor Award. Company: Arizona Public Service Company, Palo Verde Generating Station. Team: Joshua Gates, Senior Engineer, Palo Verde Generating Station; Charlie Fox, Senior Engineer, Palo Verde Generating Station; Gregory E. Falvo, WEC Principal Design Engineer Reactor Mechanicals Products II; William S. Struzenski, WEC Principal Design Engineer Reactor Mechanicals Products I; Bruce F. Allen, WEC CRDM Engineering Technical Lead, Fellow Engineer Reactor Mechanical Products. TheWestinghouse High Temperature (HT) Control Element Drive Mechanism Gripper coil was developed at the request and funding of Palo Verde Generating Station. Palo Verde and Westinghouse foresaw the need and envisioned the benefits a HT gripper coil would provide to the entire Combustion Engineering fleet of System 80 nuclear power plants. Westinghouse redesigned the Westinghouse gripper coil in order to replace the original Combustion Engineering gripper coil with a superior model. Due to the rigorous design phase, testing and quality manufacturing, the Westinghouse HT coil offers significant improvements to qualified design life and temperature as well as operating parameters at an equivalent cost. Parts Quality Initiative Drives Equipment Reliability Improvement Award Type: NEI TIP Award. Company: Exelon Corporation, Exelon Generation and BSC Supply. Team: John Makar, Scott Danehower, Meghan McQuiston. The Exelon Parts Quality Initiative (PQI) involves pre-receipt inspections and testing of critical component spare parts to identify and segregate manufacturing defects prior to being issued or installed in the plant. An innovative database and work management tool, OneLab ® , allows real-time trending and program management of more than 2,000 testing templates for specific manufacturers, models and part numbers for components in use throughout the nuclear industry. Exelon has realized a 69 percent decrease in MWe capacity losses due to manufacturing defects. Other utilities have recently started using the Exelon PQI process to drive their capacity losses down as well. Wireless Vibration Sensor Award Type: NEI TIP Award. Company: Tennessee Valley Authority. Team: Andy Pawley, TVA; Joshua Berry, TVA; Tim Bowman, TVA; Tom Fischer, TVA; John Kaplan, TVA; Brandon Schwartz, TVA; Eric Swift, TVA; Will Walker, TVA; Chris Welch, TVA. To proactively prevent plant and equipment issues by improving data flow to its Central Monitoring Center, TVA developed a remote, wireless vibration sensor that can easily be installed on nuclear plant pumps, motors and fans. The vibration sensor attaches magnetically, transmits data wirelessly using existing networks and is battery powered. It requires no cabling, mounting hardware or significant design changes (HT) Control Element Drive Mechanism Gripper Coil.
