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.

As suggested by Brissenden, it is possible to analyze the reaction rate in the unresolved resonance region by generating sets of random resonance parameters that have the correct statistical properties. Since each set of parameters is itself a random variable, an estimate of the probable error in an average-group cross section or reaction rate can be made by averaging over many random sets. This we have done for a mixture representative of fast breeder reactors and for the energy range 700 to 900 eV. This region is a typical one for studying the Doppler effect. If we make the assumption (a great oversimplification) that the response in this small energy band is typical, not only for the mean but also for the variance, then we would conclude that, if all fine groups (of width 200 eV) have the same weight, the probable error in the fissile component of the Doppler coefficient is about equal to its mean value. For the fine group itself, the probable error in the difference in the relative changes of the fission and the absorption rates is about ten times the mean value.
