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.

This paper discusses thermal design of a segmented high-temperature superconducting (HTS) magnet depending on geometry of HTS conductors, cooling system (indirect cooling or partial forced flow cooling), cooling techniques and joint resistance. For the purpose, three-dimensional heat conduction analysis was carried out with a finite element code, modeling geometry and operating condition of helical coils in a helical fusion reactor, FFHR as an example. In this analysis, liquid neon was assumed to be used as a coolant at an operating temperature of 25 K. As a heat removal technique for the joint, cooling system of a cryogenic liquid coolant with metal porous media has been proposed and it was also modeled in the heat conduction analysis. The numerical results showed that stainless steel jacket and a low thermal conductivity insulator determine temperature distribution and any cooling techniques cannot contribute to prevent the temperature rise when joint resistance increases in the case of the indirect cooling system. On the other hand, a high performance cooling technique such as metal porous media-inserted channel is effective to reduce temperature rise in the partial force cooling system.
