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.

One suggested approach to decreasing preheat of Laboratory for Laser Energetics cryotargets is to add a silicon dopant ~4 to 6 at.% to normal plasma polymer. As in the case of pure CH and CD shells used previously, the physical properties of these shells are of utmost importance to allow proper fielding for cryogenic shots. We have fabricated and characterized two types of Si-doped glow discharge polymer (GDP) capsules: single-layer Si-doped GDP shells (SiGDP) and double-layer Si-doped GDP/SCD shells (SiGDP/SCD).The Si-doped GDP shells with an ~870-m diameter and 5-m-thick walls were fabricated to meet the cryogenic direct laser fusion experiment requirements. Si-doped GDP shells with <0.25-m wall variation and 5% silicon dopant level were delivered. These cryogenic shells can survive a 1000-atm D2 or deuterium-tritium fill and cryogenic cooling without bursting or buckling. With an average buckle strength of 70 psi, a half-life of 12 s, and a D2 permeability at 20°C of 2.4 × 10-14 (mol × m/m2 × Pa × s), Si-doped GDP shells meet the criteria for cryogenic experiments. A possible drawback of the SiGDP layer is its rapid OH pickup due to exposure to air, which can increase the amount of infrared light absorbed in the shell wall as compared to D2 ice and possibly result in a poor ice uniformity during the cryogenic layering process. The absorption coefficient of the SiGDP at 3160 cm-1 measured by Fourier transform infrared spectroscopy is ~48 cm-1 at 0.1 h to ~130 cm-1 at 167 h of air exposure.
