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.

In the tandem mirror GAMMA10, confining potential is formed at the plug region in order to decrease the loss region which exists in the velocity space of ion. Furthermore to increase the confining potential effectively, the electron which flows into the plug cell from the central cell is decreased by forming a potential dip (thermal barrier potential) between the central cell and the plug cell. The electrostatic potential at the inner mirror throat (IMT) of the plug/barrier cell may decrease and act as effective thermal barrier potential because of the effects of the strongest magnetic field and the anisotropy of ion temperature in the central cell. Simultaneous measurements of both the potential and the density in the IMT region are important to investigate the potential formation mechanism.
