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.

Maintenance of the Joint European Torus (JET) reactor led to generation of soft housekeeping materials contaminated with tritium and comprising various polymeric materials. Some of the wastes fall into the category of intermediate-level waste and require processing to reduce the volume and/or change the category to low-level waste. Plasma arc centrifuge (PAC) combustion and countercurrent regime of gasification have been studied as candidates for a future waste treatment facility for JET tritium-contaminated wastes. This study was carried out for JET wastes that did not contain tritium. Mass reduction factors from 8 to 46 and from 35 to 143 for countercurrent regime of gasification and PAC combustion, respectively, have been demonstrated to be dependent on waste composition. Volume reduction factors from 20 to 100 and from 95 to 400 for countercurrent regime of gasification and PAC combustion, respectively, have been also estimated to be dependent on waste composition. The wastes and combustion products including chlorine-containing combustion products have been characterized using standard procedures and various analytical procedures developed for this study. The formation of water as a secondary waste was estimated for countercurrent regime of gasification, which was important for the ultimate processing of tritium-contaminated wastes.
