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.

A model of parallel capillaries with different diameters has been developed to explain back-diffusion experiments on four rather different graphites both impregnated and unimpregnated. The transport phenomenon has been taken as an interaction between diffusional and molecular flow on one hand, and viscous and slip flow on the other, to cover the whole range of diameter to mean-free-path ratios possible in graphite. It can be shown that only by assuming at least three bundles of capillaries with different diameters can these experiments be adequately explained. It is further possible to relate the material constants, the viscous flow component B0, and the slip flow component K0 to the pore-size distribution obtained. When we consider the complexity of porous capillaries in graphite, the agreement is found to be good, about 30%.
