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 method and a laboratory facility were developed for the purpose of determining inflammation temperature of hydrogen-oxygen gaseous mixtures (HOGM). We have determined the inflammation temperature of HOGM containing the following impurities: Ar, Xe, H2O and tritium within the range of initial gas pressure from 3 to 13 kPa. The results agree well with the available reference and numerical simulation results. The inflammation temperatures of HOGM in the range of initial gas pressure from 2 to 13 kPa increases from 793 to 873 K. Average inflammation temperatures of hydrogen and deuterium mixtures differ no more than 1.6 %. Introduction of inert gases (argon and xenon) into gaseous mixture up to 45 volume percent does not change inflammation temperature significantly. Water introduction (in the range from 2.4 to 25 volume percent) does not cause gaseous mixture inflammation. The effect of tritium -radiation on temperature of GM inflammation within the range of tritium concentration concerned is insignificant and agrees with the results of numerical modeling obtained earlier.
