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 results of studying efficiency of water detritiation by “hydrogen - water” chemical isotope exchange in laboratory-scale facility with membrane contact devices including perfluorosulfonic cationite Nafion-type membranes and platinum hydrophobic catalyst RCTU-3SM are presented. It has been shown that a decrease of detritiation efficiency caused by poisoning membranes with metal ions coming from equipment materials due to their corrosion after long-time operating the facility can be observed. It has been shown as well that modification of a membrane by metal ions followed by its regeneration allows not only to restore but also to increase significantly the efficiency of mass-transfer in membrane contact devices. For example, replacing membranes in contact devices of the laboratory-scale facility resulted in increasing the column separation degree by a factor of more than 7 in comparison to initial value obtained at similar conditions.
