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.

As a part of the ARIES-CS compact stellarator power plant study, a modular, helium-cooled, T-tube divertor design that can accommodate a peak heat load of 10 MW/m2 has been proposed. Detailed analyses have been performed using the FLUENT[registered] CFD software package to evaluate the thermal performance at the nominal design and operating conditions. Extremely high heat transfer coefficients (>40 kW/(m2-K)) have been predicted. An experimental investigation has been undertaken to validate the results of the numerical simulations. A test module which closely simulates the geometry of the proposed He-cooled T-tube divertor has been tested using air as the coolant while maintaining the same non-dimensional parameter ranges as the He-cooled T-tube divertor design. Axial and azimuthal variations of the local heat transfer coefficient have been measured over a wide range of operating conditions. The experimental data closely match the model predictions. The results of this investigation show that the model can be used with confidence in future design analyses of the T-tube divertor, as well as similar types of gas-cooled high heat flux components.
