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.

Temperature dependence of oxide layer formation on hydrogen isotope retention in stainless steel type 316 was studied by TDS and XPS. The shape of TDS spectrum was clearly changed by the oxide formation temperature. The chemical states of iron, chromium and oxygen were also evaluated by XPS. The surface oxide layer was composed of iron and oxygen and the contribution of chromium was quite low. The ratio of oxide layer on stainless steel increased as increasing the annealing temperature. The deuterium retention trapped by the oxide layer, which corresponded to the desorption temperature of 600-800 K, was governed by the ratio of oxide layer, especially iron hydroxide. All of the iron was not oxidized and the saturation ratio of iron oxide to pure iron existed in the stainless steel. It was concluded that the saturation of deuterium retention trapped by the oxide layer was controlled by the amount of iron oxide in the oxide layer.
