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 electrical resistances and Hall coefficients of polycrystalline graphite, neutron irradiated graphite, chemically doped graphite, and neutron irradiated chemically doped graphite have been measured over a range of magnetic fields at liquid nitrogen and liquid helium temperatures. The empirical equivalence of acceptor concentrations in irradiated graphite and in chemically doped graphite obtained by matching Hall coefficients has been found to be a function of the temperature of measurement. This observation may be explained in terms of temperature dependent trapping efficiencies of the electron traps introduced chemically or by neutron irradiation. This explanation affords some understanding of the electrical properties of the complicated neutron irradiated chemically doped graphite. The temperature variation of the resistances and Hall coefficients of the graphites studied may be reasonably well understood on the basis of the phenomenological theory of transport properties. Anomalous variations with magnetic field of resistances and Hall coefficients were observed at low temperature in some of the graphites studied; no satisfactory explanation has been found for these effects, although a recently introduced theory provides a plausible explanation for the observed magnetoresistance of polycrystalline graphite at liquid helium temperature.
