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.

Modifications of Rayleigh-Taylor instability growth by a gradual density increase instead of a step increase, finite fluid thickness, convection (or ablation), three-dimensional disturbances, nearby stable stratification or fixed boundaries, and nonlinear saturation are quantitatively assessed in typical model cases. To account for gradual density transitions, novel approximate but conservative correlations are given that can replace a hitherto widely used incorrect relation. The stabilizing effects of stable stratification, a fixed boundary (below), and a free surface (above) close to the instability zone are discussed in detail for the first time. For the effect of convection a new and simple derivation of Bodner’s formula is presented, which reveals that the formula describes a fictitious effect due to observation of the disturbance at a moving location. A half-analytical procedure is proposed that allows an account at the same time for several effects resulting from the actual density profile and the possible variations of this profile and its acceleration with time, for example, during ablative acceleration of thin foils.
