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.

Critical parameters are reported for uranium-solution systems consisting of equally spaced vertical cylinders arranged in a square array resting on the bottom of a 20.3-cm-high square slab tank. Some of these systems were reflected externally. Both the cylinders and the slab contained uranyl-nitrate solution having 490 g of uranium (93.2 wt% 235U)/liter. A system of an 87-cm-high array of sixteen 11.0-cm-diam cylinders on an 11.4-cm-thick solution slab was critical. The slab alone was critical at 12.8 cm. Another critical system was a single 22.4-cm-diam cylinder of effectively infinite height on a solution slab 10.8-cm thick. The 22.4-cm diameter is 93.7% of the critical diameter for an infinite cylinder. Monte Carlo calculations, simulating several typical experimental critical systems, yielded values for keff between 0.958 ± 0.012 and 0.986 ± 0.009.
