Sargent & Lundy’s Ty Holderbaum has been named to Nuclear News’ 40 Under 40 list of top young nuclear industry professionals. Holderbaum, a program manager with over 10 years of experience, was selected based on technical and professional achievements, leadership, and industry impact. His selection marks the second consecutive year a Sargent & Lundy nuclear professional has been named to the prestigious list.
“It’s an honor to be recognized alongside the other recipients on the 40 Under 40 list,” Holderbaum said. “This achievement would not have been possible without the dedication and support of my Sargent & Lundy colleagues on both the Dominion Energy and Duke Energy teams. I share this achievement with them.”
Holderbaum joined Sargent & Lundy in 2024 and has been leading the design and implementation for an extended power uprate program to increase output at two nuclear power stations by a combined 225 megawatts along with fuel-handling upgrades at two additional plants. He currently serves as the firm’s site representative managing and coordinating client and project needs at three plants.
Holderbaum, a second-generation nuclear professional, grew up around the industry and has been a strong advocate for growing and developing the workforce of engineers, skilled tradespeople, operators, and project leaders for the future. He founded and led the firm’s North American Young Generation in Nuclear – Charlotte chapter and received NAYGN’s 2024 Individual Achievement Award.
In 2025, Quinn Reynolds, a vice president with the firm was named to the 40 Under 40 list. The American Nuclear Society selects the honorees based on their work in academia, government, utilities, manufacturing, and professional consulting firms. An individual’s potential for future contributions to the nuclear community through influencing policy, engaging with the public, and pushing the field forward is also a consideration.
“Throughout his tenure with Sargent & Lundy, Ty has been a valued contributor to our team, strengthening client relationships by delivering excellent work products and meeting important deliverable milestones,” said Mike Breisch, a senior vice president who oversees many of the firm’s nuclear power projects. “Ty deserves this recognition based on his contributions to customer relationships, team cohesion, and dependable project execution.”
