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.

The application in TEXTOR of an externally controlled radial electric field Er, imposed by means of an electrode, has allowed to ascertain many aspects of the physics of the creation of Er and of its effect on radial transport. Radial conductivity was shown to depend on parallel viscosity with the latter's nonlinear response to Er providing the basic ingredient for Er bifurcation, typical for L- to H-mode transitions. Simultaneous time and space resolved measurements of Er and of the plasma flows in the edge by means of a newly developed inclined Mach probe have allowed to further substantiate the role of parallel viscosity and of neutral collisions in the damping of rotation. The causal role of grad Er in bringing about the transport changes has been proven by showing that the field shear is spatially correlated with and temporally leads the density gradient, as well as by comparison with theoretical modeling.
