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 slab is considered to be bombarded normally by a flux of gamma rays from a nuclear explosion. As a result of this bombardment, electrons are scattered from the slab with a distribution of velocities. An approximation to the velocity distribution is obtained with the Klein-Nishina theory of the Compton process, the Bethe formula for average energy loss per unit path length of an electron penetrating matter, and a correction factor accounting for the multiple scattering of the electrons. The theoretical study reveals that the electrons are scattered out of the slab predominantly into the direction of propagation of the incident gamma rays. The velocity distribution of the electrons upon emerging from the slab is peaked near the high velocity end of the spectrum; it is also shown to be independent of the slab thickness, provided the thickness is greater than the maximum range of the recoil electrons but less than the mean free path of the gamma rays. Numerical results are obtained that confirm the statements of Karzas and Latter.
