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.

A hybrid quasi-optical waveguide resonating device providing millimeter-wave beam switching and combination at high power is described in this paper. It can be realized, starting from the beam-splitting properties of the rectangular corrugated waveguide with aperture much greater than the wavelength , by arranging the waveguides in a resonating ring configuration. This kind of waveguide, cut at an appropriate length, has been proposed for the remote steering (RS) system of the ITER upper electron cyclotron resonance heating (ECRH) launcher, because of its imaging properties. In fact, beam steering can be performed far from the plasma edge since an input beam is transformed into an output beam with the same angle with the waveguide axis as the input one. Multiple imaging properties, derived by the fractional Talbot effect, are applied at waveguide sections cut at fractional lengths and lead to 3-dB beam-splitting properties for a length equivalent to half the length of an RS waveguide. Ring-type resonant devices with two outputs are obtained by setting two or more waveguides in properly arranged loops. The power distribution in the two output channels available can be controlled either mechanically, moving the mirrors used to couple the different sections by fractions of the wavelength , or varying the source frequency by a fraction / << 1. The exploitation of a second input port allows beams of different gyrotrons with nearly the same frequency to be coupled to the same transmission line. This relatively compact device can be evaluated for application into the ITER ECRH transmission line, with advantages on beam routing control.
