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 Sallen-Key filter is frequently used to realize radiation detector pulse shaping. To improve the performance of the digital pulse-shaping algorithm, we establish the full parameter Kirchhoff’s Current Law equations of the analog Sallen-Key circuit. Synthesizing these equations, a second-order nonhomogeneous difference equation is obtained. By analyzing the symmetry degree of the response function of the difference equation, an optimal pulse-shaping algorithm is derived. Given any shaping time, the parameters needed by this algorithm can be calculated easily. As well, this algorithm has no limitation on gain parameter and no undershoot. Simulation and field-programmable gate array test results validate the feasibility of the new algorithm.
