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.

The theory of Lane, Nordheim, and Sampson for the calculation of the effective resonance integral in media containing absorber in the form of small particles was tested by comparison with experiment. Measurements were made on samples containing gold particles in a range of volume fractions from 0.1 to 30%. Two diluent materials, lead and graphite, were used to test the effect of the type of material admixed with the absorber particles in the samples. Comparison of the theory and experiments was made on the basis of the calculated and measured decrease in effective resonance integral of the particle case relative to the corresponding homogeneous case with the same average absorber and diluent density. The results show that, for small absorber volume fractions, there is good agreement between theory and experiment, if the theory is suitably modified to describe the experiment. This agreement also extends to volume fractions above 10%, although the results of the theory are in question in this range.
