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.

A unified formalism is presented, which is applicable to a wide class of problems related to fast-neutron multiplying systems. Such problems are the search for asymptotic and transient space-energy modes in fast reactors and exponential or wave experiments and the analysis of pulsed or modulated bare systems. This formulation is based on the use of a Laplace transformation with respect to time and of a Fourier transformation with respect to space. It is greatly simplified, if it is assumed that the fission spectrum is independent of the energy of the incident neutron and of the nuclide that underwent fission. This assumption, which does not affect the results appreciably, makes it possible to describe the whole neutronic process in terms of a single scalar variable, the fission neutron source, (instead of the energy-dependent flux) without any loss of information. Furthermore, the solution can be found by convolutions over the neutronic processes between successive generations of fissions, which involve only simple slowing-down kernels.
