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.

Measurements of resonance absorption of neutrons were performed on single-absorber systems containing 238U and 232Th individually, and in binary systems containing mixtures of these two absorbers. The single-absorber measurements were made over a wide range of absorber concentrations and served as a check on the adequacy of resonance absorber calculations and/or resonance parameter data. The binary systems provided a situation in which the spacing of resonances is closer than in a single absorber, thus making questionable the usual assumption of separability of resonances. The measurements were performed by means of static reactivity techniques in the Advanced Reactivity Measurement Facility (ARMF-II) at the National Reactor Testing Station in Idaho. The calculated and measured values for the uranium dioxide systems are in good agreement over the wide range of absorber concentrations. The experimental results for the thorium dioxide samples are consistent with work by other experimenters but are in quantitative disagreement with resonance integrals calculated from a recent compilation of resonance parameters. The measured resonance integrals of the binary mixtures were smaller than the values predicted from the measurements on the single-absorber systems, indicating an interference effect of approximately 3% in the samples of highest absorber concentration. Calculations performed with a multiresonance version of Nordheim's ZUT code underestimated this interference effect between absorbers.
