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.

The report presents the recent results of experiments with deuterium neutral beam injection in the Gas Dynamic Trap (GDT) device. The experiments were to demonstrate the peaking up of the DD reaction near the fast ion turning points that represents the essential feature of the GDT-based neutron source (GDT-NS). The critical assumption for feasibility of GDT-NS is that the fast ion relaxation in the warm target plasma is to be determined by two-body Coulomb collisions without considerable increase of the scattering rate caused by instabilities, otherwise the neutron flux peaks may strongly flatten out. The comparison of the measured axial profile of the DD reaction intensity with simulation results allows to validate this assumption for the plasma parameters of GDT device
