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.

For the purpose of application to volume reduction of tritiated hydrogen as gaseous waste, we carried out an experimental series of pressure swing adsorption (PSA) using a column packed with synthetic zeolite 13X (SZ-13X) at 77.4 K, where a cyclic PSA process was operated enriching D2 in a H2-D2 mixture while isolating H2 from this mixture. The result demonstrates successive reduction of a volume of this mixture with successively separating purified hydrogen volumes. It is reported here that the operational efficiency of volume reduction in the PSA process using the SZ-13X column is higher than that in the same PSA process using the same column but packed with SZ-5A. The latter is already obtained in a previous work. Comprehensively, the experimental results suggest that the PSA process is applicable to the volumetric reduction for regulating the storage inventory in a tritium waste management system.
