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.

We have investigated the neutron generation characteristics of discharge-type fusion neutron source by experiments and computer simulations for several years. The cylindrical inertial electro-static confinement device used for these studies has been considered to be a point source where neutrons emitted isotropic. The aspect ratio (length divided by diameter) of the device is 1∼2. For neutron applications, a beam shape where neutrons are emitted in a specific direction may be more convenient.In this paper we describe recent results of neutronic calculations for making a beam-type neutron source by increasing aspect ratio of the device and by locating reflecting material around the device. It is found that the increase of aspect ratio of 2∼5 does not strongly affect the neutron flux distribution, but that neutron fluxes in the axial direction becomes 2∼3 times larger than those without reflectors and more than 1 order stronger than the radial direction by adding reflector.
