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 ratio of the neutron-capture cross section to the fission cross section (α) for U235 has been measured for incident neutron energies from 12 to 690 keV by a large gadolinium-loaded liquid-scintillator technique. Additional measurements at 30 and 64 keV were made by a method employing a liquid scintillator and a fission chamber. The experimental values of α can be approximately described by a linear decrease from 0.374 at 10 keV to 0.177 at 210 keV followed by a less rapid linear decrease to 0.095 at 700 keV. The results of these experiments are consistent and in reasonable agreement with other reported values of α in this energy range.
