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.

Hydrogen reemission and retention from and in the inert gas plasma sprayed tungsten (IPS-W) exposed to the plasma are described. Two kinds of irradiation scenarios are investigated in continuous and cyclic exposures. In the later a recovery phase exists between plasma exposure phases, simulated to the regular tokamak discharges. The H retention at the surface temperature Ts of 600 ~ 900 K was evaluated from 4 × 1020 m-2 to 2 × 1022 m-2 at the fluence from 1 × 1024 m-2 to 1 × 1026 m-2 under continuous exposure conditions. For the cyclic exposure, two cases associated temperature variation during the cycle, large Ts > 100 K and small < 40 K, are investigated. The temperature rise Ts dependence of the reemission and retention is observed. When Ts > 100 K, the apparent reemission is triggered by both Ts and irradiation itself, and then after the exposure stops it turns to apparent retention. However, for Ts < 40 K no reemission and retention are observed in the cycle. This fact suggests that the hydrogen reemission is enhanced during the exposure via the surface recombination process depending on Ts or Ts gradient across the specimen.
