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 study is intended to introduce an analytical approach to the transient problem of the nonlinear thermoelectric systems. The problem of predicting the output current as a function of time and that of predicting the temperature distributions in the thermoelectric elements as a function of both time and distance are determined with a given heat-input function. The analysis of the system is complicated by the following facts: 1) There exist several singularities in the system, and these singularities make the ordinary power expansions converge very slowly. 2) The boundary conditions of the initial transient and of the transient as the system approaches steady state yield two highly nonlinear differential equations of which the approximate solutions are very hard to obtain. The first problem is solved by using logarithmic and other transformations to remove the singularities. The second problem is overcome by applying the technique of the special expansion of Jacobi.
