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.

It is shown that the most suitable boundary conditions connecting the moments of the angular flux at the two faces of an annular void surrounding the fuel in a reactor lattice cell are obtained from the consistent use of the transport-theory PN approximation in the void as well as in the other media, when N is not restricted to very low values. A different procedure, which is particularly appropriate in diffusion theory, had been used previously by Newmarch and extended to N = 3 and N = 5 by Tait and Clendenin. However, the algebraic difficulties are considerable, and, although their method is preferable to the systematic use of the PN approxi- mation in all media for the lowest values of N, it is not capable of generalization to higher N. Comparisons of the different approaches are given for the lowest-order approximations; the method based on applying the PN approximation to all regions is given in a form suitable for any odd value of N, and numerical results are presented up to N = 11 to show that it converges rapidly.
