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.

Macroscopic behavior of a high-beta and supersonic plasma flow produced by a magneto-plasma-dynamic arcjet (MPDA) was investigated in the HITOP device. A macroscopic instability was observed as a bulk rotation of the plasma plume eccentrically around the center axis of the vacuum vessel. We investigated whether it was caused by current-driven or pressure-driven instability. A plasma current circulating in the plasma plume was controlled by changing discharge current, magnetic field configuration and mass flow rate and by inserting a copper-mesh grid. It was found that the plasma plume was macroscopically stable when the current extending into the plasma plume was low and the safety factor was more than unity. This indicates that the observed macroscopic instability was mainly caused by a current-driven one.
