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.

Aqueous homogeneous reactor fuel solutions have been examined spectrophotometrically in the wavelength range 0.3 to 1.2µ as a function of time, temperature, and overpressures of hydrogen and/or oxygen. Using a cell that was designed for liquid-gas equilibration, and which were slightly catalytic for the recombination of hydrogen and oxygen, the course of reactions (reduction, hydrolysis, precipitation, oxidation, and re-solution) of uranium and copper were followed concomitantly. Degassed solutions of the UO2SO4-CuSO4-D2SO4-D2 O-H2O system lost uranium and copper very slowly above 200°C. In the presence of hydrogen, Cu(II) and U(VI) were reduced consecutively to Cu (metal) and to U(IV) species that were partially soluble at 25°C, but insoluble above 150 to 200°C. The changing spectrum was generally uncomplicated by turbidity, since reduction of Cu(II), as well as aggregation of U(IV) hydrolytic species, occurred at the cell wall. Hydrolysis of U(IV) was slowly reversible with decreasing temperature. Reoxidation of reduced solution with oxygen was comparatively rapid and complete at all temperatures.
