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.

Over the past few years SCKCEN has been focusing on the treatment of tritiated organic liquid waste. The experimental method that we are studying is a complete two-stage combustion with thermal and catalytic oxidation of the organic liquid into tritiated water for further treatment and tritium free off gases for discharge. Our first task involved the treatment of about 200 liters of tritiated organic solvent, with a total activity of around 17 TBq. We were able to completely treat this solvent with only limited discharges to the environment. The second application of this technology was a study to treat tritiated organic liquids from the Joint European Torus (JET). We started with cold tests using virgin and inactive oil and liquid scintillation cocktail. As a final step, batches of tritiated feedstock were treated to demonstrate the viability of the process and facility. We conclude that our technology is both technically feasible and safe and can be adapted for the treatment of various categories of problematic tritiated liquid waste, which will undoubtedly be produced in existing installations and in future fusion reactors.
