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.

Solutions obtained by expansion in a series of spatial modes and by an iterative method are compared for both space and space-time problems. In the space problem, the modal expansion is used to justify the iterative results. A useful nonlinear transformation is introduced to aid in solving multi-mode approximations. The space-dependent fast adiabatic excursion model, or Fuchs-Nordheim model, is solved by a novel iterative approach. This iterative solution is valid for large disturbances, as well as small, thus improving results obtained by approximate modal expansions. The derivation of the space-independent Fuchs-Nordheim model from the space-dependent equation is shown to follow in a more straightforward manner than derivations based on modal approximations.
