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.

A major challenge in nuclear fusion research is the coherent combination of measurements from heterogeneous diagnostics. Different measurement techniques for measuring the same subset of physical parameters provide complementary and redundant data for, e.g., improving the reliability of physical parameters, increasing the spatial and temporal resolution of profiles, and resolving data inconsistencies.The concept of integrated data analysis within the framework of Bayesian probability theory was applied to the combined analysis of lithium beam emission spectroscopy (LIB), deuterium cyanide laser interferometry, electron cyclotron emission (ECE), and Thomson scattering spectroscopy. The four heterogeneous diagnostics enable the simultaneous estimation of electron density and temperature profiles with high spatial and temporal resolution. The coherent analysis of the profile diagnostics allows one to consider diagnostic interdependencies correlating density and temperature profiles, e.g., ECE shine-through, and diagnostics alignment. The benefits of a combined analysis of diagnostics will be shown in a modular way by successively increasing the set of diagnostics starting with the LIB diagnostics.
