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.

Recent study of fusion reactions within an inertial electrostatic confinement (IEC) device revealed several significant modes of fusion: converged core, beam-target, beam-background, and charge-exchange reactions. In an attempt to understand the fusion product proton measurements in the IEC device, the advanced fuel D-D and D-3He fusion proton energy spectra were analyzed. For D-3He fusion, the beam-target reactions were found to dominate. Hence, the present study focuses on understanding the beam-target reactions and the corresponding proton energy spectra from such sources. This information helps in accurately calculating the proton flux for optimizing medical isotope production and other near-term applications, besides calibration of the proton detectors.A proton detector was used to measure the experimental data and the Monte Carlo stopping power and range in matter (SRIM) simulation code was used to explain the corresponding experimental observations. While the D-D proton spectrum from the IEC device showed combined Doppler and scatter broadening, the D-3He proton spectrum, besides showing the broadening, also shows some interesting characteristics such as a high-energy tail and a detector thickness-dependent energy spectrum. An extended high-energy tail occurs in the observed energy spectrum from the detector because some of the protons go through the wire before being detected, which reduces their total energy. Due to the higher proton stopping power in the detector at somewhat lower energies than the initial 14.7 MeV, these protons thus deposit a larger fraction of their energy and create the high-energy tail. These measurements show that the high-energy tail of the proton energy spectrum should be excluded from the total proton counts for an accurate proton rate measurement.
