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.

Understanding and control of impurity transport is one of the important issues to reduce the impurity in fusion plasmas. Being based on the Binary Collision Monte-Carlo Model (BCM), a numerical model for classical/neo-classical cross field transport of impurity ions in magnetic fusion devices is being developed. The purpose of the present study is to examine, step by step, whether our proposed model correctly reproduces 1) classical and 2) neo-classical transport processes of impurity ions. The numerical results agree well with theoretical values by classical theory. Not only self-diffusion, but also impurity flow in the direction along the background density gradient has been reproduced. In addition, good agreement of diffusion coefficient with neoclassical theory has been obtained in the wide range of collisionality parameter in a simple tokamak magnetic configuration.
