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.

An effective heat transfer enhancement scheme is required to compensate for the decrease in heat transfer due to MHD effects in FLiBe based blanket design of fusion reactor. In present study, a twisted tape is selected as a potential candidate for a turbulence promoter, and a thermohydraulic behavior of turbulent flow of an electrically conducting fluid in a non-conducting pipe with twisted tape insertion under a transverse magnetic field is investigated. As a result, significant decrease of heat transfer performance is not observed compared with the same flow without the tape insertion because the heat transfer is dominated by the strong helical flow which is not suppressed by the magnetic field.
