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 scattering kernel for liquid diphenyl has been determined from a model for the diphenyl molecule in which the carbon and hydrogen atoms make harmonic oscillations about their equilibrium position. The hindered translations and rotations of the molecule as a whole, which are characteristic of the liquid state, were considred as free translations of the molecule to which an effective mass was associated. A set of interatomic force constants which describes the vibrational motions of the molecule was found and then used for a complete normal-mode calculation. These force constants were calculated, using a modified least-squares technique which gives the best fit for the vibrational frequencies of the molecule measured by optical techniques. The amplitude vectors calculated from the computed set of force constants were used, together with the measured vibrational frequencies, to construct the weighted frequency spectrum used in the slow-neutron calculations. The scattering law was computed, in the harmonic approximation, by means of the code GASKET. The code FLANGE was used to interpolate the scattering law and to produce the scattering kernel. The total scattering cross section, the single differential cross section, and other neutron parameters were calculated and compared with experimental data with gratifying results.
