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.

Dose as a function of depth in tissue has been calculated for the case of solar-flare protons incident isotropically on slab shields followed by tissue slabs. The flare used has a spectrum that is exponential in rigidity with a characteristic rigidity P0 of 80 MV. Only incident protons with energies between 0 and 400 MeV are considered. Slab thicknesses of 4 and 20 g/cm2 of aluminum are considered and a tissue thickness of 30 cm is used. In general, it is found that the secondary contribution to the dose is small unless thick shields are considered. In particular, the secondary neutrons from flare protons with energy of less than 50 MeV do not contribute appreciably to the dose in the cases considered here.
