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 detailed experimental study on the kinetics of a 238U sphere is described. The measurements involve the use of nanosecond electronics and silicon solid-state detector with two fission conversion foils: 235U and 237Np. Thus, some information on the time-energy coupling was obtained. The results show a nonexponential behavior over all time ranges. At longer times, the space and time coupling was small. At early times, the coupling between energy space and time was strong. The early time behavior of the high-energy neutrons (above 237Np threshold) appears to be exponential. The decay constant, however, is a function of position. It is shown that this exponential behavior is a result of a “pseudo-trapping” of neutrons between the fast fission threshold in 237Np and the large step in the inelastic scattering cross section of 238U.
