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.

Refinements to consequence modelling for hypothetical accidents in Fusion Power Plants have been explored. This leads to improved accuracy and a reduction in some of the conservatism inherent in previous calculations. Assumptions made in previous analyses for the Safety and Environmental Assessment of Fusion Power (SEAFP) are examined, with particular emphasis given to aerosol modelling within the containment and dispersion and dose calculations. By employing a more realistic treatment of the time dependence in the aerosol model and introducing a procedure for accounting for the effects of wind meander, it is shown how to obtain results which may be used to adjust previously derived dose estimates. Further analysis assesses the possibility of aerosol particle removal by filtering in cracks in the containment barriers, as material leaks into the environment. The potential for mitigation by this mechanism has been neglected in previous calculations.
