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 neutron transmission of 99Tc for neutron energies less than 1 keV has been measured with the Material Testing Reactor (MTR) fast chopper with a resolution of 0.04 to 1.8 µsec/meter. A total neutron cross section at 0.0253 eV of 24.7 ± 1.7 b was obtained. To fit the cross-section data in the thermal energy range, it was necessary to assume a contribution by a bound level together with contributions from measured resonances at positive energies. Resonance parameters are presented for levels observed in the energy region from 0.01 to 300 eV. Two additional resonances, not listed in the literature, have been measured and analyzed. Parameters of individual resonances below 300 eV and average parameters at higher energies, give a resonance absorption integral of 340 ± 20 b, and a value of (0.43 ± 0.14) × 10−4 for the s-wave neutron strength function.
