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 neutron-capture cross section of 1.0-year Ru106 has been determined from the yield of 22-min Rh107 formed in reactor irradiations. The average of four measurements is 0.146 barns. The experimental error is about ±7% but when systematic errors are included, largely in gamma-ray abundances from Ru106 and Rh107 decay, the uncertainty is about 30%. Cadmium-ratio measurements were made and the resonance-capture integral, including the 1/υ part, was found to be 2.0 ± 0.6 barns for an effective cadmium cutoff of 0.54 eV. These results are relative to a cobalt thermal neutron-capture cross section of 37.5 barns and total resonance integral of 72.7 barns. It has been assumed that neutron capture by Rh106, Ru107 and Rh107 is negligible, that the cross section of Ru106 in the thermal region has a 1/υ dependence and that the neutron spectrum is 1/E in the resonance region.
