Nuclear Power Generation Systems Lab

Undergraduate Research Assistant | 2023-2024

Director: Dr. Rick Williams

I joined the NPGS Lab in Fall 2023 to design and implement a combination analog and digital control system for pump and valve simulator. While there I also assisted in outreach and instruction for nuclear power in the Auburn/Opelika area through K-12 engineering events and created documentation for facilities and lab curriculum within the Nuclear Power Generation Systems academic minor.

I also presented at the 101st Annual Alabama Academy of Science presentation and received first place honors for my presentation entitled "Troubleshooting Nuclear: A Student Centric Teaching Aid". The abstract for the presentation is included below:

In response to the critical need for systematic troubleshooting in nuclear power plant operations, we have developed a pump loop system designed to provide immersive training for college students. This system comprises an arrangement of four motor-operated valves, three centrifugal pumps, and one positive displacement pump, arranged in series and parallel configurations, as well as relevant sensing equipment. The system also features a heater, chiller, and filter to more closely mimic plant conditions. It is engineered to replicate common plant problems such as valve leakage, damaged pump impellers, and instrument failures, offering students a hands-on opportunity to diagnose and rectify issues.

Our system enables students to engage with both analog controls, including switches and hand-operated valves, and digital controls via LabVIEW, reflecting the complexity of real-world plant operations. This dual approach facilitates an understanding of the key concepts of defense in depth and redundant systems.  The system also emphasizes plant operation concepts like pump and system curves, the operational differences between positive displacement and centrifugal pumps, and the dynamics of pump flow in series and parallel configurations, along with interlock logic.

While the construction of the system is still nearing completion, its design philosophy emphasizes hands-on troubleshooting under simulated plant conditions. One such condition is the ability to conduct exercises with students positioned in a detached "Control Room," communicating with an operator stationed at the pump loop. This setup not only mirrors actual plant operation scenarios but also enhances teamwork and communication skills critical for future engineers.
