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 ITER Electron Cyclotron Heating (ECH) system will produce a high-intensity beam of electromagnetic radiation for plasma heating. A total of 20 MW of power will be transferred from 170 GHz gyrotrons through multiple transmission lines. The transmission lines consist of evacuated, aluminum, circularly corrugated waveguides that will each transmit up to 1.5 MW for up to 3600 seconds. The waveguides, as well as mirror and polarizer components, will be actively water cooled in order to support the heat load from the long-pulse high-power radiation. Transmission lines will be as long as 200 meters, made up of individual lengths of 2 to 4 meter pieces that are joined by couplings. These couplings must retain high vacuum during operation, and maintain a very high degree of straightness between adjacent waveguide pieces. Analyses have been performed to examine various parameters of the design of these couplings, and confirm that stringent criteria are met during installation and operation. Further couplings are used to join the waveguide to other transmission line components, such as miter bends, expansion units, and switches. All of these are analyzed to confirm structural integrity during operation.
