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.

We researched the AIC (Alfvén Ion Cyclotron) instability. A magnetic probe using microchip-inductor is superior to size and easy to handle. In fluctuation measurement using the GNBP (Gold Neutral Beam Probe) the measured fluctuations may not be local density fluctuation because the beam ionization coefficient depends on not only the electron density but also the temperature, and the secondary beam is deflected by the magnetic field fluctuation, and the beam fluctuation is integrated along the beam trajectory. But we found by simulations such as the AIC fluctuation with small amplitude and high frequency these effects may be neglected. In initial experiment, the GNBP detected successfully the AIC fluctuations with high frequencies excited in the core plasma.
