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.

Complete evaluations of the (n,2n) and (n,3n) reaction cross sections were carried out for the stable isotopes of lead and for natural lead, that element being a potential neutron amplifier for fusion blankets. The method of computation used is based on the Segev simple formalism for compound nucleus decay without branching. This method, which was already checked for 204Pb, was used for cross-section computation for all other stable lead isotopes. From these results, evaluated cross sections could be derived for natural lead. The results of the evaluations were in good agreement with experimental data. Small discrepancies with the measured data for 204Pb, 207Pb, and 208Pb at low excitation energies above threshold are overcome through the introduction of an “effective” threshold energy slightly higher than the real one. This single correction is sufficient for matching the shape of the evaluated curves to the measured data over the entire energy range for the second neutron emission.
