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 Cs2LiYCl6:Ce3+ (CLYC) scintillator is being widely employed in nuclear physics, planetary science, radiation environmental monitoring, nuclear security, and nonproliferation communities. The time resolution of a 1 × 1-in. CLYC scintillation detector is reported in this paper. It was measured by the use of a high sampling rate DRS4 waveform digitizer and an EJ-309 liquid scintillation detector. The digitizer was first characterized with regard to its intrinsic time resolution and then the time resolution of the EJ-309 detector was investigated. It served as a reference detector in the time resolution measurements for the CLYC detector. The time pick-off techniques used were the constant fraction discrimination and leading edge discrimination methods. In addition, the Savitzky-Golay filter was used to further improve the measured time resolutions. This filter was shown to be an effective approach to improving time resolution when the signal-to-noise ratio is low.
