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.

Superconducting magnets have complex structures. The coil pack is made up of alternate layers of superconductor and insulator, which form an extremely unisotropic composite structure. For example, the MFTF magnet design, the transverse stiffness is quite soft as compared to the circumferential stiffness [1]. In this study, cylindrically wound superconducting magnets were modeled by two-dimensional multi-rings connected by soft springs, and the internal vibration and buckling of the system were studied both experimentally and analytically. Since the linear elastic theory used in the previous studies [2,3] has failed to predict buckling and vibration of internal turns in the bending mode, elastic ring theory was used in this study. A model based on ring theory and magnetic stiffness was developed to explain experimental observations and showed a fair to good agreement between experimental and theoretical values of the buckling current.
