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 thermal performance of multilayer PVD tungsten and molybdenum coatings on graphite was studied for the application of first wall in nuclear fusion devices. The coatings with a thickness of 5 μm and different numbers of W/Mo layer were prepared and a series of plasma thermal loads from 1.3 to 4.1 MWm-2 was applied. Microstructure changes caused by thermal loadings were analyzed. Scratch test was then conducted to quantify the changes in the adhesion. The microstructural analysis and scratch test results showed that the thermal performance of the coatings varied depending on the degree of heat loads and coating structure. A molybdenum interlayer improved the coating adhesion while the plasma heat resistance of the double-layer W/Mo coating was slightly better than the others.
