From operator to entrepreneur: David Garcia applies outage management lessons
David Garcia
If ComEd’s Zion plant in northern Illinois hadn’t closed in 1998, David Garcia might still be there, where he got his start in nuclear power as an operator at age 24.
But in his ninth year working there, Zion closed, and Garcia moved on to a series of new roles—including at Wisconsin’s Point Beach plant, the corporate offices of Minnesota’s Xcel Energy, and on the supplier side at PaR Nuclear—into an on-the-job education that he augmented with degrees in business and divinity that he sought later in life.
Garcia started his own company—Waymaker Resource Group—in 2014. Recently, Waymaker has been supporting Holtec’s restart project at the Palisades plant with staffing and analysis. Palisades sits almost exactly due east of the fully decommissioned Zion site on the other side of Lake Michigan and is poised to operate again after what amounts to an extended outage of more than three years. Holtec also plans to build more reactors at the same site.
For Garcia, the takeaway is clear: “This industry is not going away. Nuclear power and the adjacent industries that support nuclear power—and clean energy, period—are going to be needed for decades upon decades.”
In July, Garcia talked with Nuclear News staff writer Susan Gallier about his career and what he has learned about running successful outages and other projects.

An analytical study is performed to determine the threshold value of the Peclet number below which conventional Nusselt number relations are invalidated by the effect of streamwise heat conduction. The investigation encompasses the Prandtl number range of liquid metals. Consideration is given to pure forced-convection boundary layer flow on a flat plate and to the forced-convection boundary layer on a vertical plate with superposed free convection. If Pex, Rex, and Grx, respectively, denote the Peclet, Reynolds, and Grashof numbers, all based on the streamwise coordinate x, then the threshold value of Pex is found to range from 12 to 7 as Grx/Rex2 ranges from 0 (pure forced convection) to 1.0. The present analysis does not provide Nusselt number results for very low Peclet numbers, where streamwise conduction effects play a decisive role.
