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.

Using the sphere transmission and time-of-flight techniques, the neutron spectra emitted from 0.58 and 3.0 mfp of nitrogen and from 0.72 mfp of oxygen have been measured for a 14-MeV neutron source. The analysis of the data has been done using the Livermore Monte Carlo Neutron-Transport Program (SORS). Good agreement was obtained for nitrogen with a revised SORS calculation, where five inelastic levels are explicitly included in the computational routine for the (n,n′) cross sections. To obtain agreement between calculations and measurements for oxygen, the computational model had to be extended so that it could account for the presence of inelastic levels. A revision of the cross sections was also carried out. With these new versions of SORS, excellent fits to the experimental measurements for nitrogen and oxygen were obtained. Using the revised SORS program, calculations for the transport of neutrons in air from a 14-MeV point neutron source were obtained.
